Firefly Aerospace’s Blue Ghost landed in Mare Crisium at 3:34 a.m. Eastern time on March 2, 2025. It arrived upright, deployed its communications hardware and began a surface campaign that lasted from lunar morning to lunar sunset.

That sequence made Blue Ghost the first fully successful commercial Moon landing, but not the first commercial soft landing. Intuitive Machines’ Odysseus had reached the surface a year earlier and continued transmitting from its side. The distinction matters because Blue Ghost’s achievement was not just surviving touchdown. It was remaining in the attitude required to use its power, communications and instruments as designed.

There is also a language trap in the phrase “lunar day.” At one place on the Moon, sunrise to the next sunrise takes about 29.5 Earth days. Blue Ghost operated through the daylight half of that cycle, logging 346 hours in sunlight, then continued for just over five hours after sunset. That is the approximately 14-Earth-day surface mission that lunar engineers often call one lunar day.

Three private attempts had reached the surface first

Before 2025, three privately led landers had reached the Moon. SpaceIL’s Beresheet crashed in April 2019 after a failure during descent. Japan’s ispace lost HAKUTO-R Mission 1 in April 2023 when its navigation software concluded too early that the spacecraft was at the surface. The lander exhausted its propellant and fell.

Odysseus changed the category in February 2024. It made the first commercial soft landing and returned engineering and science data for more than 160 hours, but it came to rest on its side. NASA’s lunar mission catalogue records both parts of that result: a soft landing and a posture that interfered with communications.

Astrobotic’s Peregrine is not part of this count because a propulsion failure prevented it from reaching the lunar surface. Government missions such as Japan’s SLIM are also outside a comparison about privately built landers. “Private” describes the organisation that built and operated the spacecraft, not the origin of every dollar. Blue Ghost’s customer was NASA, and its ten payloads flew through NASA’s Commercial Lunar Payload Services programme.

One of those earlier failures has acquired a second history. Space Daily’s account of Beresheet examined the tardigrades carried inside its lunar library. That unusual cargo should not obscure the engineering result: the lander reached the Moon at destructive speed.

Upright was an operational condition

A lander’s posture determines which solar cells see the Sun, whether its high-gain antenna can point toward Earth and whether instruments can deploy into clear space. A tipped vehicle may remain alive, as Odysseus showed, but its mission becomes an improvised recovery exercise. Power, heat flow and radio links no longer match the geometry tested on Earth.

Blue Ghost launched on January 15 and spent 45 days travelling to the Moon. It descended near Mons Latreille in the Mare Crisium basin, using terrain-relative navigation and hazard avoidance to compare camera images with stored maps and select safe ground. After touchdown, images of the deck, horizon and lander’s shadow confirmed that it was stable.

Standing up did not guarantee a successful mission, but it preserved the design assumptions needed for one. Space Daily’s pre-landing coverage described the flight software and photovoltaic assemblies supporting the journey. On the surface, those systems could finally work in the orientation for which they had been built.

The daylight clock started at landing

The landing was timed near local sunrise. That gave the solar-powered spacecraft almost the maximum useful interval before the Sun disappeared. As the Sun climbed, the thermal problem changed from cold to heat. Firefly reported surface temperatures around 121 degrees Celsius near lunar noon and temporarily powered down some systems as part of planned thermal management.

The Moon turns once relative to the Sun in about 29.5 Earth days. A point near the equator therefore receives roughly two weeks of daylight followed by roughly two weeks of night. Blue Ghost’s mission record gives the precise operational tally: 346 hours of daylight, or 14 days and 10 hours, followed by just over five hours in lunar night.

In this context, returning data “throughout” a lunar day means that the campaign extended across the full sunrise-to-sunset interval. It does not mean that every instrument transmitted without interruption every second, nor that the lander survived an entire day-and-night cycle.

Ten NASA payloads used the time

All ten NASA science and technology payloads powered on, collected data and operated on the surface. Lunar PlanetVac used compressed nitrogen to lift, move and sort regolith without a conventional scoop. LISTER drilled below the surface to measure thermal conductivity and heat flow. The six SCALPSS cameras photographed how the descent engine plume disturbed the ground, then continued observing through sunset.

The Lunar GNSS Receiver Experiment, or LuGRE, acquired GPS and Galileo signals at lunar distance and calculated navigation fixes in lunar orbit and on the surface. Space Daily reported the result when NASA confirmed it, noting that satellite navigation signals designed for Earth could still be detected far beyond their intended service region.

The Electrodynamic Dust Shield used electric fields to remove abrasive grains from test surfaces, while the Lunar Magnetotelluric Sounder measured electric and magnetic fields to probe the Moon’s interior. These were not all-or-nothing demonstrations. Each generated data that still required calibration and analysis after the lander stopped transmitting.

Sunset was a planned finish

Blue Ghost was not designed to survive the lunar night. When sunset arrived on March 16, falling solar input began the expected end of the mission. The lander kept operating for a little more than five hours into darkness. Firefly received the final data at about 6:15 p.m. Central Daylight Time.

This was power loss in the literal sense, but not an unexpected electrical failure. The vehicle had reached the boundary built into its energy and thermal budgets. As Space Daily has explained, a typical lunar night lasts about 354 hours and exposed surface temperatures can fall toward minus 173 degrees Celsius. Surviving it requires heaters, insulation and stored energy that add mass to a lander.

Firefly’s end-of-mission release reported more than 119 gigabytes returned during the trip and surface campaign, including 51 gigabytes of science and technology data. Blue Ghost also photographed a total eclipse from the Moon and recorded lunar sunset. Those images are part of the data, not merely souvenirs; researchers can use them to investigate dust behaviour and reports of horizon glow.

A successful landing is more than the touchdown

Blue Ghost did not make commercial lunar landing routine. Four days later, Intuitive Machines’ Athena landed near the south pole but ended on its side, sharply limiting operations. ispace’s Resilience crashed during its June 2025 attempt. The title’s pre-2025 boundary is important: the mixed record continued after Blue Ghost.

Nor should the mission be treated as privately financed exploration detached from government. NASA purchased the delivery and supplied the payloads, while Firefly supplied the lander, flight team and mission operations. CLPS deliberately divides responsibility that way in an attempt to buy lunar delivery as a service while companies develop reusable institutional knowledge.

Blue Ghost’s place in the record rests on the whole chain: controlled descent, upright touchdown, stable power and communications, ten operating payloads and a planned shutdown after sunset. The landing lasted seconds. The evidence of success accumulated over the next 346 daylight hours.

For a few years in the early 1990s, a lot of New York streets sparkled. Picture a Manhattan avenue at dusk, wet from a passing shower, the streetlights and headlights catching something in the road surface itself. Not the usual dull black, but a faint, restless glitter, as if the asphalt had been dusted with something. That shimmer was crushed bottles. The city had figured out how to grind its glass waste into the road.

The material had a name that told you exactly what it was: glassphalt. It went from a curiosity nobody trusted, to something people demanded outside their own buildings, and then it quietly disappeared. And it’s a small case study in why good recycling ideas so often don’t stick.

The glittering street, and why the city made it

Asphalt is mostly sand and gravel held together by a black binder. Glassphalt is what you get when crushed glass replaces part of that sand and gravel.

The Federal Highway Administration, in its guidelines on waste glass in pavement, says road-surface mixes with roughly 10 to 15 percent crushed glass perform fine. From 1989, the city’s transportation department started putting the glass content of its mix at about 10 percent.

The FHWA called the New York program the “most aggressive” glass-recycling paving effort in the country. From 1990 through 1995 the city used roughly 225,000 metric tons, about 250,000 tons, of glass in resurfacing. By 1991, crews had already laid glassphalt on nearly 900 lane-miles of Manhattan and Brooklyn streets.

What made the idea clever, as far as we can tell, is the kind of glass it used. Bottle recyclers want clean glass sorted by color. They won’t buy the mixed-color material that piles up at the bottom of a recycling stream. Glassphalt didn’t care about color. It could swallow exactly the low-value waste glass that nobody else wanted and turn it into road. The city reported saving about $500,000 a year by using crushed glass in place of some sand and gravel, and keeping 38,000 tons of glass out of landfills in the process.

From public suspicion to actual demand

People did not warm to it right away. A road that shimmers looks, at first glance, like something is wrong with it. But the turnaround, if the accounts from the time are right, was fairly complete.

Harold Watson, the transportation department’s assistant commissioner for asphalt operations, had become something of an in-house champion for the material. Watson said in 1991: “Now, when we do a road, if we don’t have glass on it, people come in and start complaining.”

That’s a nice story about public mood, not a measured fact, and it comes from a fan of the material, so we’d hold it loosely. Watson was clearly frustrated by a quieter resistance too. In his telling, “There’s a lot of people who can’t find anything wrong with glassphalt but won’t say anything good about it.” Read that as one supporter’s view rather than a neutral account, but it captures the odd spot the material was in: hard to fault, hard to fully endorse.

The Plaza, and a request for more sparkle

The clearest sign that the public had come around involved one very visible stretch of Fifth Avenue. After the city resurfaced the section in front of the Plaza Hotel with glassphalt, the hotel’s owner, Donald Trump, wanted the surrounding streets given the same treatment. A recycled-glass road surface had become something worth lobbying for outside a luxury hotel.

There’s something funny in that. The exact same crushed bottles a bottle plant would reject as worthless were, when spread across Fifth Avenue and lit up after rain, a selling point. The sparkle did real marketing work that the engineering never asked for.

Why the biggest glass-paving program in the country faded

None of the appeal saved it. The program’s central weakness was that its raw material came from curbside recycling collection, and collection is expensive.

During a budget crisis, Mayor David Dinkins floated suspending the recycling operation to save about $65 million a year, which would have cut off the glass supply. Commissioner Lucius Riccio said at the time: “That would be a shame. We’re doing a record amount of paving and we could use all the glass they could give us.” That tension is the whole story in miniature. The paving side wanted all the glass it could get, and the collection side that fed it was the first thing on the chopping block when money got tight.

What we take from a road paved with bottles

New York didn’t invent glassphalt. Baltimore had paved at least 17 streets with it from the mid-1970s through the mid-1980s, chasing the same sparkle.

What New York proved was that the idea could run at real scale, absorb hundreds of thousands of tons of the exact glass nobody else wanted, and win over a skeptical public along the way.

The sparkle was arguably the least interesting thing about it. It got the headlines, it got Trump lobbying, it made a wet avenue look faintly enchanted. But the real achievement was much plainer: a workable use for low-value mixed glass that would otherwise cost money to bury.

The reason it faded had nothing to do with whether the roads glittered, and everything to do with the fragile system behind it, the collection network and the raw cost of glass against dirt-cheap gravel. A recycling idea can be sound as engineering and still lose to logistics. That, more than the shine, is what a road made of bottles has to teach.

The post Beginning in 1990, New York City repaved streets with asphalt containing crushed recycled glass. By 1995, crews had used 250,000 tons of glass in resurfacing applications across the city, including a section of Fifth Avenue in front of the Plaza Hotel. appeared first on Space Daily.

One family in Port Washington, Wisconsin sold 173 acres for $10.2 million. On the county’s books, that same ground was valued at $590,000. That comes to roughly $59,000 an acre, about 17 times the assessed figure, according to a Wisconsin Watch analysis of Ozaukee County property records. 

It is tempting to read it as pure luck. Somebody’s farmland turned out to be worth twenty times what the tax roll said, the buyers overpaid, and a few landowners got rich. Parts of that are true. But the 17x gap is telling you something more specific, and the distance between what the assessor saw and what a data center developer would pay is the real story.

This article is for general information only, not financial, tax or real estate advice, and it is not a property appraisal or valuation. The prices discussed reflect particular transactions and should not be used to estimate what your own land is worth. Consult a qualified local appraiser or adviser before making property decisions.

What a 17x number is really measuring

A fair market value on a tax roll estimates what a buyer would pay for a parcel used the way it has always been used. In Port Washington, that meant farmland priced as farmland. It was never meant to capture what the same dirt is worth to a company assembling a site for a giant computing campus a mile inland from Lake Michigan.

The developer is Denver-based Vantage Data Centers, which broke ground on a 672-acre campus called Lighthouse on the city’s north side. It is the Midwest site of OpenAI and Oracle’s Stargate project. Vantage describes it as 2.5 million square feet of building, with completion targeted for 2028. A project that size does not want scattered plots. It wants one large, continuous block, locked down before a rival gets there.

That is why the assessed value and the sale price split so far apart. They answer different questions. One asks what the land is worth as land. The other asks what it is worth as the last missing piece of a $15 billion build.

The claim worth pushing back on

The idea that a price this high is just free money is where we’d push back. Not because nobody profited, plainly some people did, but because it treats the gap as proof the buyers were foolish or the sellers simply blessed.

The mayor’s version of the lucky-landowner story is memorable. Ted Neitzke, the project’s most prominent supporter, told Wisconsin Watch that the sellers “woke up one day and they just happened to live in the right spot.”

Right spot, yes. But “happened to” undersells what was being bought. Wisconsin Watch notes that, nationally, data center developers are often willing to overpay for land near electric power, to beat rivals in what has become a land rush. The premium is not a mistake. It is the price of speed and certainty in a market where losing one parcel can strand an entire campus.

Adam Mauro, a valuation director at Altus Group, put this plainly in a study of 80 data center land deals. The high price for well-placed land, he wrote, “is compensation for immediacy and certainty, not an indicator of superior underlying real estate.” That is one firm’s view rather than settled fact, but it fits Port Washington closely. The buyers were not paying for better dirt. They were paying to not lose.

Why single parcels commanded outsized prices

That $10.2 million deal did not happen alone. Wisconsin Watch found developers spent at least $125 million assembling 1,500 or more acres around the project, buying from individual owners at many times the assessed value. Members of the Karrels family and their farming business earned at least $20 million across their deals.

When you have to stitch together that much neighboring ground, every last holdout gains power. As Scott Finfer, a Texas land developer writing for HousingWire, put it, “data centers typically require hundreds of contiguous acres to deploy capital at scale.” If your farm sits in the middle of the block a developer needs, its value is not what farmland trades for. Its value is what the whole project is worth without it, which is nothing.

Altus Group’s numbers show the same dynamic from the other side. Its analysis found a roughly 120-fold spread in per-acre prices depending on parcel size: a median near $3.3 million an acre for sites under 25 acres, versus about $28,000 an acre for tracts over 1,000 acres. Small, well-placed pieces cost far more per acre precisely because the buyer cannot walk away from them.

What the sale price doesn’t capture

The land is the cheap part. A campus this size runs on water and power, and those carry costs the purchase prices never show. Vantage says it is funding a minimum of $175 million in regional infrastructure: water and wastewater capacity, mains, sewer lines, a new water tower and power hookups. Against numbers like that, a $125 million land bill looks more like a down payment than the main event.

The residents’ side is more mixed than either the windfall story or the horror story allows. Ryan Nowak sold his 65-acre Lake Drive property for $1.75 million and now lives about 10 miles north. “On paper it looked OK,” he told Wisconsin Watch, “until you go to replace what you had.”

Curtiss Smith, a crane operator who sold a four-acre property assessed at $258,000 for $895,000, described the strange feeling afterward: “After the fact, you hear what everybody else got.” Neither man says he was cheated. They are describing what it feels like to put a price on something that had never been priced before.

Port Washington is not unusual, which is part of why the multiples look the way they do. Land purchases for future US data centers reached about $6 billion in the first half of 2026, up 79% from a year earlier, according to figures from Avison Young reported by CNBC. Data centers now make up 27% of US development sites, second only to apartment buildings. A local land rush and a national one are the same thing at different scales.

What a fair-market figure can and can’t tell you

An assessed value is a good measure of what land is worth for the use it already has, and a poor measure of what it is worth to a buyer who needs that exact acre right now. The 17x figure does not mean the land was secretly premium. It is the price of speed, of buying a continuous block, of being the one parcel a $15 billion project cannot route around.

In 2021, the average transaction recorded on the Bitcoin blockchain carried an estimated water footprint of roughly 16,000 litres, once the water used to generate the electricity behind the mining process and to cool the machines doing the work is added up. That figure, drawn from a peer-reviewed study published in the Cell Press journal Cell Reports Sustainability, works out to roughly 6.2 million times the water footprint of a single credit-card swipe, based on de Vries’ own estimate — discussed in a later interview with Greenpeace rather than the paper itself — that one card transaction carries a footprint of around 2.6 millilitres.

The research, titled “Bitcoin’s growing water footprint,” was published online in late November 2023 by Alex de Vries, a data scientist with a background in financial economics who tracks the industry’s resource use. De Vries built his estimate around two components. The larger of the two, accounting for roughly 80 to 90 percent of the total, is indirect water use: the water consumed at power plants to generate the electricity that miners buy, whether through evaporative cooling at thermoelectric plants, hydropower reservoir evaporation, or other generation methods. The paper calculates this by combining data on where Bitcoin’s computing power is located with regional water-intensity figures, expressed in litres of water per kilowatt-hour of electricity produced on that grid.

The remaining share, direct water use, covers cooling and humidification equipment on-site at mining facilities, measured using an industry metric called water usage effectiveness, or WUE. For large-scale US mining operations, the study estimated a weighted-average WUE of between 0.25 and 1.03 litres per kilowatt-hour, depending on climate and facility design. Location matters enormously to the total: the study estimated Kazakhstan accounted for 63 percent of Bitcoin’s 2021 water footprint while hosting only around 14 percent of its computing power. Average water intensity across Bitcoin’s power mix rose from 8.63 litres per kilowatt-hour in 2020 to 15.0 litres per kilowatt-hour in 2021, the paper found.

What the comparisons mean

News coverage of the study, including reporting by ScienceDaily and Fast Company, popularized the comparison that a single Bitcoin transaction’s water footprint is roughly equivalent to filling a backyard swimming pool. The 6.2-million-times-a-credit-card-swipe comparison, cited in de Vries’ own commentary and repeated across outlets covering the paper, follows from dividing the 16,000-plus-litre figure by that credit-card baseline, and it moves with Bitcoin’s price. When the market fell during the 2022 downturn, mining activity and its associated electricity and water use fell with it, only to climb back toward record levels as the price recovered in 2023. Because a higher Bitcoin price makes mining more profitable and draws more computing power onto the network, the water footprint tracks the price cycle instead of holding steady. De Vries projected the network’s total 2023 water footprint at roughly 2,237 gigaliters, an increase over 2021 despite the intervening price crash.

Extrapolated to the United States, which absorbed a large share of mining capacity after China’s ban, de Vries estimated domestic mining operations consume water at a scale comparable to roughly 300,000 US households, or a city on the order of Washington, DC, a comparison he discussed in an interview with Greenpeace.

Where the estimate is contested

The methodology has drawn pushback. Critics covered in a DL News investigation note that per-transaction water figures are largely independent of transaction count — a block can bundle thousands of individual payments, so dividing total resource use by the number of on-chain transactions can make the per-transaction number swing based on how the network happens to be used that day — a shift in usage patterns, not a genuine efficiency change.

Bitcoin advocate Daniel Batten has gone further, arguing in commentary covered by the same report that the swimming-pool framing overstates the case by counting indirect water use from power generation that would occur with or without Bitcoin mining, and that applying the same accounting method to other electricity-intensive industries — banking, AI, search engines, construction, or media — would produce similarly large-sounding numbers. Separately, a UN-affiliated water researcher, Kaveh Madani, flagged in the same report that “water footprint” and “water consumption” are technical terms with distinct meanings in hydrology, and that using them interchangeably in public communication risks overstating the case. The Register’s coverage of the dispute frames it as a live disagreement between the paper’s author and its critics — not a settled question.

Why it matters beyond the headline number

The debate sits inside a larger and less disputed trend: much of Bitcoin mining has moved into regions and grids with high water intensity, including coal-heavy and drought-prone areas, since China’s 2021 mining ban scattered the industry’s computing power across new jurisdictions. That shift, documented in mining-location data tracked separately by the University of Cambridge, means Bitcoin’s water footprint is now heavily influenced by decisions about where mining farms are sited and what power sources they draw on, in addition to how much Bitcoin is worth on any given day. For a network whose environmental accounting has focused almost entirely on carbon and electricity for over a decade, the 2023 paper marked one of the first attempts to put a number on the water side of the ledger as well.

The post A single Bitcoin transaction carried an average water footprint of about 16,000 litres in 2021 once the electricity and cooling behind it were counted — roughly 6.2 million times the water behind one credit-card swipe, and the figure rises and falls with the price of Bitcoin itself appeared first on Space Daily.

A man’s voice reads a date onto a plastic disc. “The date, 7 March, 1949,” he says, as reported by Smithsonian Magazine. Underneath the announcement there is something else: a low, looping sound with a shape to it, rising and falling. It came up through the water off Bermuda into an experimental rig the researchers had lowered over the side.

They did not know what it was. They kept it anyway.

What they had captured, as noted by Woods Hole Oceanographic Institution, was the song of a humpback whale and it sat in a drawer for the better part of a century before anyone could say so.

A sound nobody could place

The recording came out of ordinary work. In March 1949, researchers aboard WHOI’s research vessel, the R/V Atlantis, were off Bermuda testing sonar for the U.S. Office of Naval Research.

The gear was makeshift by later standards: an early underwater setup and a Gray Audograph, an office dictation machine that etched sound onto thin plastic discs. Into that they fed noises coming up from below that they could not explain.

WHOI’s announcement in February 2026 identified that March 7, 1949 disc as what may be the earliest preserved recording of a whale. The hedging in that sentence matters, and we’ll come back to it. The striking part, for now, is the gap. The people at the rail heard the sound as they made it. The people who understood it were born, in some cases, decades later.

Why it sat unheard for seventy-seven years

The disc survived partly by luck of material. Magnetic tape from that era tends to break down; plastic holds up better. As Ashley Jester, WHOI’s director of research data and library services, put it, “these audograph discs survived because of their material and careful preservation.”

The 1949 disc is one of more than 200 audograph discs in WHOI’s archives, only a handful of which have been listened to so far. Digitizing the collection was funded by a $10,000 award from the National Recording Preservation Foundation. It took someone deliberately going back through old plastic, disc by disc, for the unexplained sound of 1949 to become the humpback song of 2026.

Made before we knew what whale song was

What makes the timing land is what came after it. The idea that humpbacks sing structured, repeating songs is usually traced to the 1960s. Navy engineer Frank Watlington recorded humpbacks off Bermuda in 1964 and shared his tapes with Roger and Katharine Payne. That work led to the album “Songs of the Humpback Whale,” which put the idea into the public mind that these animals compose.

The 1949 disc predates all of that by fifteen years. The researchers who saved it had no framework to hear it with. To them it was noise worth keeping, not song worth studying, because the idea of humpback song as a thing to study did not yet exist.

That gap is also what gives the old recording its value now. Laela Sayigh, a marine bioacoustician at WHOI, framed the scarcity plainly: “Data from this time period simply don’t exist in most cases,” she said. Her point, as we read it, is not that no mid-century ocean audio survives anywhere, but that this window is close to blank, which is what makes a single clean disc worth so much.

Sayigh suggested the recording “can provide insight into how humpback whale sounds have changed over time, as well as serving as a baseline for measuring how human activity shapes the ocean soundscape.” 

Peter Tyack, an emeritus research scholar at WHOI, made the same point about what the disc lets you hear beyond the whale. The recordings, Tyack said, “not only allow us to follow whale sounds, but they also tell us what the ocean soundscape was like in the late 1940s,” adding, “That’s very difficult to reconstruct otherwise.”

Why “may be the oldest” is the careful phrasing

WHOI has been careful, and we think that care is worth keeping. “May be the earliest preserved recording of a whale” is not the same claim as “is the oldest whale recording.” Older discs could be sitting unlistened-to in the same collection, or in someone else’s. The institution is describing what it has found and verified, not making a claim about everything that ever existed. When a headline flattens that into a superlative, it drops the part of the sentence that’s actually accurate.

That caution reflects how thin the evidence is. For context, WHOI points to other archives, including the Ocean Alliance collection of more than 2,400 recordings of whale and ocean sound from the 1950s through the 1990s. Even so, the 1940s remain close to silent in the record. A hedge isn’t weakness in a claim like this. It’s the accurate shape of what’s known.

The case for keeping what you can’t explain

Nobody in 1949 filed that disc thinking they’d captured the oldest whale song on record. They filed it because it was data, and you keep data. The understanding arrived seventy-seven years late, delivered to people the original researchers never met.

Jester put it plainly. “These recordings remind us why we collect data, even when we don’t immediately know what it means,” she said, and framed it as a duty across time: “preserving data when it is created is an investment in the future of science.”

The post In 1949, researchers testing underwater acoustics off Bermuda lowered an early recording system into the water and kept the unexplained sounds it picked up. Seventy-seven years later they were identified as what may be the oldest preserved recording of a whale singing, made before scientists understood humpback whale song. appeared first on Space Daily.

You want to put fish into a high mountain lake, one with no road and no short trail to it. Fish need water to travel in, water is heavy, and no truck can get up there. So how do you do it?

Utah’s answer, worked out over decades, is to skip the ground entirely. The fish arrive by air, and for the final stretch they arrive through open air, falling out of an airplane into the lake below.

The method: a Cessna, seven chambers, and a low pass

The plane doing this work is a small single-engine aircraft, and its cargo hold is the clever part. The Utah Division of Wildlife Resources describes a plane that “can carry the pilot and a copilot, plus one fish tank that has seven chambers, allowing the aircraft to stock seven different lakes in one flight.” Seven chambers, seven lakes, one loop through the mountains before the plane comes back to reload.

The plane comes in low and slow over the lake, about 50 to 150 feet above the water, and releases the fish from one chamber so they tumble the last stretch down. Then on to the next lake, the next chamber. A single flight can carry over 10,000 fish before anyone needs to land and refill.

Why the fish survive a fall from a plane

This is the part that stops most people. A fall from a hundred feet or more, into water, sounds like the end of the fish. It mostly isn’t, and the reason comes down to size.

The fish being dropped are tiny. They are fingerlings, young fish only 1 to 3 inches long, and at that scale the physics works in their favor. The DWR’s own explanation is that “the young fish — called fingerlings — are so small (ranging from 1-3 inches long) that the air slows their drop. The slower fall allows the fish to survive.” A body that small weighs very little for its size, so air resistance slows it fast. Instead of dropping like a stone, the fish flutter down more the way a leaf does.

We are not fish biologists, and this is the agency’s account of its own program rather than an independent study, so it reads better as the DWR’s reasoning than as settled fact. The agency is clear about the size limit, though. If you tried this with bigger fish, the DWR says, “if the fish were larger, the survival rate would not be as high.” The whole method depends on keeping the fish small enough to fall gently.

How long this has gone on, and how far it reaches

Dropping fish from planes is not a recent experiment. Utah has done it since as early as 1956, and it wasn’t the first method anyone tried. Matt McKell, a biologist with the DWR’s Northern Region, has written about the earlier, more awkward approaches. In the early days, McKell has written, the fish were carried up in metal milk cans on horseback. A horse can only carry so much water so far up a mountain.

Aircraft solved the reach problem, and they stuck. McKell writes that “by the 1950s, small airplanes became the preferred method for stocking fish into backcountry lakes, which is actually still the case today.” Seventy years on, the plane handles the long-distance work, while backpacks, buckets, and four-wheelers still cover the lakes a person can walk or drive to.

The scale now is large. The DWR reports that “more than 300 lakes are aerially stocked in Utah each year. These lakes range in size from smaller than 5 acres up to 500 acres.” Independent reporting puts the figure at roughly 300 high-elevation lakes as well, so the number is not just an agency talking point.

Why bother stocking a barren lake at all

There is a fair question underneath all of this. Many of these high lakes hold no fish naturally. Steep outlets and long winters mean fish often can’t reach them or can’t breed once there, which is exactly why they require frequent stocking rather than a one-time drop. So why put fish in a place that can’t keep them going on its own?

The plain answer is recreation. These are backcountry fishing spots, and a lake with no fish is a long hike to nothing for an angler. Stocking keeps hundreds of remote lakes worth the walk.

What makes the whole operation possible circles back to the fingerlings. The airplane, the seven chambers, the low pass over the water, all of it works only because the fish are small enough that falling a hundred feet does them little harm. Grow them a few inches and the physics turns against you. The program depends, in the end, on dropping a creature light enough to be caught by the air on the way down.

The post Young fish are dropped from a small airplane over Utah’s mountain lakes, poured out of one tank divided into seven chambers so the fish fall the last stretch through open air. More than 300 lakes inaccessible by vehicle are stocked this way each year, a practice Utah has used since 1956. appeared first on Space Daily.

One amateur naturalist, working in a modest backyard outside Boston, kept a colony of caterpillars behind his house. A windstorm scattered some of them into the woods and a little over a century later, the descendants of those loose larvae had become one of the most expensive forest pests on the continent, able to chew bare more than a million acres of trees in a single bad year.

How does one careless moment on a residential lot in 1869 turn into that?

The short answer: it took twenty years to look like anything at all. That delay is what makes the story worth telling. So let us walk it forward from the yard.

Who Trouvelot was, and what he was trying to do

The man in the yard was Étienne Léopold Trouvelot, a French amateur naturalist and artist who had settled in Medford, Massachusetts. He was not trying to unleash anything. He was experimenting with silk production. Trouvelot wanted to breed a silk-spinning caterpillar more resistant to disease than the domesticated silkworm.

For that he turned to the European gypsy moth, a species the Entomological Society of America formally renamed the “spongy moth” in 2022.

As the education service EEK tells it, some of Trouvelot’s moths escaped in 1868–1869 and subsequently multiplied in a vacant lot next to his home in Medford, Massachusetts. Not a secret rogue experiment. A hobbyist’s version of a reasonable farming bet, gone wrong in the most ordinary way imaginable.

The escape

It is often said that eggs got loose. The record does not quite support that. Trouvelot had imported clumps of eggs, but what escaped were the caterpillars he was actively raising behind his house.

According to historical accounts, a windstorm damaged his nets and scattered the caterpillars. Smithsonian magazine’s account of the episode traces the whole invasion back to insects escaping from nets and cages in that backyard.

Two things about the insect made the accident far worse than it should have been. It had few natural predators in North America. And the female of this species cannot fly, which sounds as though it should have limited the spread. But the young caterpillars compensate by floating on threads of silk carried by the wind, giving the moth almost nothing eating it and a quiet, wind-driven way of moving across the landscape.

The twenty-year fuse

For roughly two decades, not much visibly happened. That is the part that trips up our intuition. We expect consequences to arrive on the same timescale as the mistake, and invasions rarely oblige. The population built generation after generation until it crossed a threshold.

The first recorded major outbreak came around 1889, about twenty years after the escape. Caterpillars stripped the leaves off fruit and shade trees across a 360-square-mile area around Medford. 

Massachusetts launched a campaign to wipe the moth out, and the methods of the day were blunt. Ken Gooch, forest health program director at the Massachusetts Department of Conservation and Recreation, described that early era to the Daily Hampshire Gazette: “They did an incredible amount of really, really toxic pesticide spraying.” 

The effort failed. The moth kept moving, spreading through the Northeast, the Mid-Atlantic and the Midwest over the following century. Reporting from Grist puts that historical march at roughly 13 miles per year for over a century, and the total damage between 1970 and 2013 at 81 million acres stripped of leaves.

Why it still matters

The caterpillars are not fussy eaters. The USDA notes they feed on more than 300 species of trees and shrubs, which is a large part of why the damage scales the way it does.

Losing leaves for one summer does not usually kill a mature tree. Repeated years do real harm. Brian Eshenaur, a plant pathologist with Cornell University’s Integrated Pest Management Program, explained the strain to Grist: “When trees are defoliated like this right at this time of year, they are using reserves that are in the trunk and in the roots to put out a second flush of growth.” A stripped tree burns through its stored energy to grow a new set of leaves. Drain those reserves year after year and the tree weakens.

The same reporting notes that after two straight years of feeding, up to 80 percent of the trees in a hardwood forest can die. That is a cited figure, not a guarantee, and how far it plays out depends on drought, tree species and how healthy the forest was to begin with.

The financial toll is large too. Missouri’s Department of Conservation puts the yearly cost of damage nationwide at an estimated $868 million.

Wiping the moth out is off the table now. The goal is containment, run through the federal Slow the Spread program. It pairs a network of traps with two other tools: chemical scents that disrupt mating, and treatment sprayed from aircraft. A natural ally also arrived on its own in 1989, when a fungus, Entomophaga maimaiga, was found attacking the caterpillars and has since helped knock back some outbreaks.

What stays with us is the shape of the timeline. Slow-fuse invasions teach the hardest lesson precisely because there is no alarm at the moment it matters. A colony scattered by a storm in 1869 sat almost invisibly in the woods for two decades before it announced itself across 360 square miles. More than 150 years later, a multi-state partnership is still spending money and effort to hold the line against it. The gap between the small careless moment and the long tail of its consequences is enormous, and nothing about the yard in 1869 would have let anyone see it coming.

Near the base of the Dallol hydrothermal field in Ethiopia’s Afar region sits a pond barely 60 meters long, its water tinted pale yellow by dissolved iron. Chemists who sampled it found a total dissolved solids concentration of 433 grams per kilogram — 43.3 percent by weight — making it, by current measurement, the record for saltiest lake documented anywhere on Earth. The pond is known locally as Gaet’ale, and the figure comes from a 2017 study by Pérez and Chebude of Addis Ababa University’s Department of Chemistry, published in the journal Aquatic Geochemistry.

For context, the world’s oceans average about 35 grams of dissolved salt per liter, according to NOAA ocean salinity data and the USGS salinity reference — putting Gaet’ale at roughly twelve times ocean salinity. That figure is also higher than the Dead Sea, whose salinity is commonly cited around 340 grams per liter in recent measurements, though older or differently calculated figures put it lower — Guinness’s own comparison table, for instance, lists it at 23.1 percent by weight.

Ordinary seawater’s salt is mostly sodium chloride, or ordinary table salt. Gaet’ale’s brine is instead built around calcium chloride and magnesium chloride, at concentrations of roughly 2.72 moles per kilogram and 1.43 moles per kilogram respectively, according to Pérez and Chebude’s analysis, with trace sodium, potassium, nitrate and iron(III) complexes responsible for the water’s yellow cast. The researchers noted the pond’s chemistry closely resembles that of Don Juan Pond in Antarctica’s Dry Valleys, another calcium-chloride-dominated hypersaline pool long studied as one of Earth’s most extreme aquatic environments, though Gaet’ale’s higher temperature allows it to hold even more dissolved salt before reaching saturation.

The pond itself is shallow and crescent-shaped, sitting at around 50 to 55 degrees Celsius, with no inflowing or outflowing stream. According to the Gaet’ale Pond entry, local accounts attribute the pond’s formation to a January 2005 earthquake that reactivated a dormant thermal spring. The broader depression sits more than 100 meters below sea level in places, part of a tectonically stretched landscape laced with active volcanoes, sulfur vents and salt flats left behind by an ancient sea that repeatedly flooded and evaporated over geological time. The nearby Dallol hydrothermal field, roughly four kilometers northwest of the pond, is famous for acid ponds in shades of green, orange and yellow, produced when magma-heated groundwater dissolves the buried salt and mineral layers and pushes the resulting brine back to the surface.

A natural laboratory for other worlds

The combination of heat, acidity and salinity has made the region a working laboratory for scientists who study the outer edges of habitability. A multinational research effort coordinated through the Europlanet research infrastructure has sent microbiologists, geologists and planetary scientists to the depression in recent years. Karen Olsson-Francis and Vincent Rennie of the Open University sampled acidic, saline channels there for signs of microbial survival; Hugo Moors and Mieke De Craen of Belgium’s SCK CEN nuclear research center used the site to test methods relevant to how microbes might behave around deep nuclear waste repositories; and planetary geologists Daniel Mège of the Polish Academy of Sciences and Ernst Hauber of the German Aerospace Center studied Danakil’s salt-and-magma hydrothermal structures as an analog for Martian rift systems, work feeding into ongoing observations from the ExoMars Trace Gas Orbiter.

Jani Radebaugh of Brigham Young University and Ralph Lorenz of Johns Hopkins University’s Applied Physics Laboratory have separately used terrain models from the depression to interpret surface roughness data relevant to Saturn’s moon Titan.

Where even extremophiles give up

The scientific interest in the region’s brine pools goes beyond geology. A 2019 study led by Purificación López-García of the French National Centre for Scientific Research (CNRS), working with researchers from Spain’s Geological and Mining Institute and the Autonomous University of Madrid, searched the most extreme pools in the Dallol field — hyperacidic, near-boiling and saturated with salt simultaneously — for any trace of microbial life. Using genetic sequencing, culturing attempts, flow cytometry and electron microscopy, the team reported finding none, a result summarized by Phys.org as evidence that liquid water alone does not guarantee habitability. The researchers concluded that the pools’ combination of high magnesium and calcium concentrations, extreme acidity and heat produces a “chaotropic” chemical environment that actively breaks down biological molecules instead of simply placing them under stress.

That finding matters for astrobiology because it complicates a common assumption: that any environment with liquid water, however extreme, should host at least some microbial life. A separate 2021 study of nearby, slightly less extreme hypersaline lakes in the Danakil Depression, published in Environmental Microbiology by researchers including members of the same French-Spanish collaboration, found the opposite — diverse communities of salt-loving archaea thriving right up to the edge of what those less punishing pools could support. Gaet’ale itself is hot and dominated by chaotropic calcium and magnesium salts, not the sodium chloride of ordinary seawater. Pérez and Chebude’s 2017 paper focused on the pond’s chemistry rather than a dedicated search for microbial life, but a separate 2021 metagenomic study of Gaet’ale specifically found it dominated by bacteria — unlike the sterile conditions found in Dallol’s most extreme pools.

Together, the pond’s chemistry and its surrounding hydrothermal field illustrate why the Danakil Depression continues to draw researchers from chemistry, microbiology and planetary science alike. A 60-meter pool of scalding, mineral-saturated brine is, on its own, a curiosity of extreme terrestrial chemistry. Set inside a landscape already used to model early Earth, present-day Mars and the hydrocarbon lakes of Titan, it becomes a reference point for a broader question: how much stress a chemical system can absorb before it stops being able to host life at all.

The post A pond in Ethiopia’s Danakil Depression has a measured salinity of 433 grams per kilogram — roughly twelve times saltier than the open ocean and saltier than the Dead Sea — sitting inside one of the hottest, most hostile landscapes on the planet appeared first on Space Daily.

When a pipeline company condemns a strip of your land and the pipeline is already going in, what are you actually fighting for? Not the land.

By the time the Terry family walked into federal court in Roanoke, that had been decided somewhere else, and it was never going to be reopened in front of a jury. All that was left on the table was money.

That distinction is the whole story of what happened to a 560-acre tract on Bent Mountain, in Roanoke County, Virginia, land the family had held for seven generations. It helps explain how a four-day trial ended with a $523,327 verdict, and why that number then moved twice before it stuck.

We’re not lawyers, and this article is for general information only—not legal advice. It summarises a particular dispute; eminent-domain rules and compensation depend on the jurisdiction and the facts of each case. If a pipeline or other project affects your property, consult a qualified lawyer in your jurisdiction.

What actually gets taken, and why the pipeline stays

An easement is not the same as buying land outright. Mountain Valley Pipeline took permanent and temporary easements totaling about 8.37 acres across the 560-acre tract, plus a wide strip to lay and maintain the line. The family still owns the ground. What they lost was the right to control that corridor, and, in the family’s telling, some of the value of everything around it.

The power to do this comes from the Natural Gas Act, which lets an approved interstate pipeline use federal eminent domain. An explainer from the University of Maryland’s Agriculture Law Education Initiative lays out the two things a landowner can contest: whether the taking is really for a public use, and how much they are owed. The Terrys had lost the first fight before this trial began. The pipeline already had its public-use certificate, so the corridor was staying no matter what a jury decided. Only the second question, the amount, was live.

That is the constitutional floor the whole dispute sits on. The Fifth Amendment protection against taking private property without just compensation, the Supreme Court held in Armstrong v. United States, “was designed to bar the Government from forcing some people alone to bear public burdens which, in all fairness and justice, should be borne by the public as a whole.” The land goes to a public purpose. The public, through the taker, pays what it’s worth. Deciding that last figure was the entire job of the court.

Why it came down to two appraisers

When the only question is money, an eminent domain trial tends to collapse into a contest between valuation experts. In this case, these were not slightly apart. They were looking at the same land and describing two different properties.

The family’s appraiser valued the whole tract at $1.9 million, resting that figure in part on the land’s potential use as a commercial wind farm. From there the family asked the jury for $570,000, roughly a 30% loss in value.

Mountain Valley’s appraiser, Joseph Thompson, put the property at about $1.2 million before the taking and figured the damage at a much smaller reduction. At trial, the company’s attorneys argued the Terrys were owed about $153,000.

Back in 2018, Mountain Valley’s original offer for the roughly eight-acre easement was about $119,000. The family refused, the company condemned the corridor and began cutting trees, and four years later a jury was asked to sort out the gap between the company’s figure and the family’s.

How a jury lands on $523,000

The verdict, $523,327, sat much closer to the family’s number than the company’s. Juries in these cases don’t have to pick one appraiser’s total and adopt it whole. They weigh what they find believable from each side and can settle on a figure neither party explicitly proposed. That flexibility is exactly what turned into the next fight.

After the verdict came in, the judge decided the jury had gone too far. U.S. District Judge Elizabeth Dillon set the $523,327 aside, finding it ran against the clear weight of the evidence. In her 2023 opinion, she concluded the award was more than twice the highest loss in value anyone had presented, and she entered a reduced judgment of $261,033 instead.

Why the final figure moved twice

The number the jury spoke was not, for a while, the number that counted. The family appealed, and in May 2024 the U.S. Court of Appeals for the Fourth Circuit reversed the district court and ordered the full $523,327 verdict reinstated. The panel held the award fell within the range of testimony the jury was allowed to believe, and that the property’s residential values alone could support it.

Three numbers, then, for one strip of ground: the pipeline comapany’s $153,000, the judge’s $261,033, and the jury’s  $523,327. The verdict survived, but only after a second round of litigation over whether the jurors had been allowed to reach it.

What strikes us, reading the case from start to finish, is how narrow the argument always was. Four days of trial, dueling appraisers, a $1.9 million valuation against a $1.2 million one, a wind farm that will never be built, and two more years of appeals, all of it about one thing: the size of a check.

The corridor was cut, the trees were down, and the pipeline was going where the pipeline was going. The only thing anyone could still win was a number, and the number was never going to buy the land back.

The post In 2018, a gas pipeline company took an easement across a Virginia family’s 560-acre property on Bent Mountain. After years of fighting over compensation, the family won a $523,000 jury award—but the company kept its right to use the land. appeared first on Space Daily.

If you told most people that a country’s public health strategy involved deliberately breeding and releasing millions of mosquitoes a week, they would assume something had gone terribly wrong. Mosquitoes are the enemy. You spray them, you drain their breeding sites, you cover yourself in repellent. You do not, under any circumstances, run a facility that produces them by the millions and sends employees out on scheduled morning shifts to let them loose in residential neighbourhoods.

But that is exactly what the Singapore government has been doing since 2016, and the results are now peer-reviewed, published in the New England Journal of Medicine, and genuinely stunning. Once you understand the trick, this becomes one of the most elegant pieces of public health engineering you will ever come across.

The mosquitoes on purpose

Singapore’s National Environment Agency runs the whole thing under the name Project Wolbachia. At its production facility, technicians breed Aedes aegypti mosquitoes at industrial scale. These are the same mosquitoes that transmit dengue, Zika, and chikungunya. The ones being bred here, however, have been infected with a bacterium called Wolbachia pipientis, specifically the wAlbB strain, which occurs naturally in many insect species but is not typically found in Aedes aegypti.

Once the mosquitoes reach the pupal stage, the facility sorts them by sex. Only males get released, twice a week on weekday mornings, into the residential neighbourhoods where the programme is running. Here is the key point that catches everyone off guard: male mosquitoes do not bite. Only females do. Males feed on nectar. So releasing them by the million into your neighbourhood adds precisely zero to the local biting-mosquito problem.

If you like the idea of a country quietly engineering its own wildlife, this one goes further. Singapore spent sixty years turning itself into the greenest city on earth — and then had to deal with what actually moved in. Worth a watch:

What happens when they mate

The Wolbachia trick works through something called cytoplasmic incompatibility. When a male carrying Wolbachia mates with a wild female that does not carry the bacterium, her eggs get fertilised, they look normal, she lays them, and then nothing hatches. The bacterium disrupts the very first cell division in the developing embryo. Every egg is a dead end.

You can see where this is heading. Do this twice a week for months on end across an entire neighbourhood, with millions of released males competing for every wild female’s attention, and the wild mosquito population starts collapsing. The females run out of viable mates. The next generation shrinks. Eventually you are looking at a neighbourhood where the mosquitoes that could give you dengue have effectively been erased from the local landscape.

The numbers, which are extraordinary

The peer-reviewed results were published in the New England Journal of Medicine in February 2026, and they held up under the most demanding trial design available. Fifteen residential clusters across Singapore, holding a combined 724,428 people. Eight got the Wolbachia releases. Seven got nothing. The researchers tracked every dengue test result from those 15 clusters for two years, from mid-2022 to late 2024.

In the treated clusters, adult female Aedes aegypti populations dropped by roughly 78 per cent, from a baseline abundance index of 0.18 down to 0.041. In the untreated control clusters, the population actually rose over the same period, from 0.19 up to 0.277. And the dengue outcomes matched: residents in the release areas were 71 to 72 per cent less likely to contract dengue than residents in the untreated areas. The effect held across every age group, both sexes, and every year of the trial.

Where it is going next

You might reasonably wonder how much of Singapore is covered. According to the NEA’s latest update in March 2026, Project Wolbachia is protecting about 35 per cent of Singapore households, on track to hit 50 per cent by the end of 2026, with new release sites launching this year in Bukit Panjang, Little India, Pioneer, Toa Payoh, and Ang Mo Kio. Total household coverage will exceed 800,000 homes.

The programme is not officially a silver bullet. Singapore’s environment minister has been careful to emphasise that Wolbachia releases complement rather than replace the traditional approach of source reduction, insecticide spraying, and public education. But the picture is shifting fast. What started as a small phase 1 trial in 2016 is now a nationwide vector control programme that other tropical cities are studying carefully.

What this actually is

Look, I know this sounds like science fiction. A city that fights mosquitoes by breeding more mosquitoes. Eggs that never hatch because a bacterium interferes with cell division. Millions of male insects released weekly into apartment blocks where no one notices because males never bite. Every piece of it is real, all of it has been through the highest tier of peer review, and it is working better than any dengue intervention that came before it.

The reason it works is that the technique does not try to poison the mosquitoes, trap them, or block them from breeding. It just gives the wild females a whole lot of male suitors whose reproductive contribution is zero. The wild population outcompetes itself. That is judo. And Singapore, of all places, turned out to be exactly the right setting to prove it works.

The post Dengue cases have fallen by about 70 percent in the parts of Singapore where the government releases mosquitoes on purpose. It breeds 5 million males a week, none of which bite, and the females they mate with lay eggs that never hatch. appeared first on Space Daily.

Marine biologists have documented five species of wrasse in the western Atlantic using rocks, coral rubble and shells as makeshift anvils to crack open crabs, mollusks and other armored prey — a foraging technique already documented in fish from the Indo-Pacific but never before filmed in the Atlantic. A study published in Coral Reefs in March 2025 provides the first evidence of anvil use in three of the five species and the first video documentation of the behavior in the other two.

The wrasses behind the discovery

The research, led by Dr. Juliette Tariel-Adam of the Fish Lab at Macquarie University’s School of Natural Sciences in Sydney, focused on New World wrasses in the genus Halichoeres: the slippery dick (H. bivittatus), the Brazilian wrasse (H. brasiliensis), the yellowhead wrasse (H. garnoti), the black-ear wrasse (H. poeyi), and the puddingwife wrasse (H. radiatus), documented at Fernando de Noronha Island off Brazil’s northeast coast.

The paper lists co-authors Jaqueline G. Toledo, C. E. O’Brien, Sergio R. Floeter and Professor Culum Brown alongside Tariel-Adam. Anvil use in fish is not new to science. Since it was first documented in an orange-dotted tuskfish roughly fifteen years ago, researchers have logged the behavior in roughly two dozen of the more than 550 known wrasse species, almost all of them in the Indo-Pacific and Indian Ocean. What sets this study apart is geography and scale: it is the first systematic documentation of anvil use among wrasses native to the western Atlantic, and it draws on the largest video dataset yet assembled for the behavior in this ocean basin.

The team built that dataset by turning to citizen scientists. Divers, snorkelers and underwater photographers working across the Caribbean, the Caicos Islands and Brazil submitted footage and written accounts through a public call for observations, contributing 16 new records to the study. Combined with existing records, the dataset gave researchers close, repeated looks at details of the behavior that had previously been described only impressionistically.

How the fish crack their prey

Fish in the study grabbed a hard-shelled item — in most cases a crab, mollusk, sea urchin or hermit crab — and swam it to a chosen surface before repeatedly slamming it against that surface to crack it open. Successful cracking attempts required an average of six or more strikes and took at least a minute to complete, and prey was successfully accessed and consumed in 12 of the 19 documented events, according to the published paper. One of the study’s more striking findings involves anvil choice. 

The wrasses used a range of materials as anvils — rock outcrops, coral rubble, reef platforms and shells — without sticking to a single preferred striking surface, switching anvils mid-attempt in 53 percent of observed strikes.

Researchers interpreted this flexibility as a sign the fish are actively assessing which surface will most efficiently break a given prey item rather than relying on a classic bite-and-swim mechanism regardless of the target.

Researchers make the case for fish cognition

Tariel-Adam framed the findings as part of a broader case for taking fish cognition seriously. “Tool use is typically associated with humans, but this behaviour is proof that fish are far cleverer than they get credit for,” she said, in comments reported by Phys.org. Senior author Culum Brown, who has spent much of his career studying fish behavior and welfare, added that the wrasses “demonstrate flexible and dexterous tool use, expanding our understanding of tool use evolution in the animal kingdom.”

The paper situates the discovery within debates over how and why tool use evolves. Because anvil use has now turned up independently in wrasse lineages on opposite sides of the globe, the behavior increasingly looks like a foraging strategy that several unrelated reef fish lineages have independently evolved — one that is easily missed by divers not specifically watching for it, which is part of why the researchers built their dataset largely around community-contributed footage, supplemented by only a handful of controlled observations.

Coverage of the paper by Scimex and Oceanographic magazine both note that the research team is continuing to solicit new footage from divers and underwater photographers, on the expectation that further observations will clarify how widespread the behavior is among western Atlantic reef fish and whether other genera beyond Halichoeres practice it as well.

Further detail on the study is available via the Macquarie University research profile and additional reporting from ZME Science.

Karen Baker runs the Yolo Food Bank in Northern California’s Yolo County, which she describes as the most food-insecure county in the state. When CBS News California Investigates told her, on camera, that California had been sitting on money that belonged to her organisation, she asked one question: was it really hers? It was.

Tens of millions of Americans are in the same position, without a journalist on hand to tell them.

Where the money comes from

Every US state runs an unclaimed property program, which is essentially a lost and found for cash. The National Association of Unclaimed Property Administrators, the body that coordinates those programs across all fifty states, estimates that about one in seven Americans has something waiting. Searching costs nothing.

Nothing glamorous, mostly. Dormant savings accounts, uncashed payroll cheques, utility deposits from a flat someone moved out of in 2009, insurance payouts nobody told the family about, share dividends posted to an address three moves ago, and the contents of safe deposit boxes whose renters died or forgot.

Companies do not get to keep this stuff. State law obliges banks, insurers and other holders to hand it over once an account has gone quiet for a set period, typically three years in California, as the State Controller’s unclaimed property division explains. The state then holds it. There is no deadline to claim, and no fee.

The scale of the pile

California alone is minding about $15 billion in unclaimed property, per the State Controller’s Office, spread across tens of millions of individual records. New York is worse, or better, depending on your perspective: the Office of the New York State Comptroller oversees $19 billion in unclaimed funds, some of it dating back to 1943, and returned $504 million of it in a single fiscal year.

Nationally, the numbers move. NAUPA’s own annual report put total returns at $4.49 billion to Americans in fiscal 2024. That sounds like a lot until you set it against what is still sitting there.

What the states do while they wait

So what happens to the money while it waits to be claimed? In many states, it flows straight into general operations, and the state keeps whatever it earns until someone comes looking.

Citing the California Legislative Analyst’s Office and state budget documents, CBS News reported that unclaimed property is one of California’s top General Fund revenue sources, generating around $1 billion a year, while the state has returned roughly 3.5 per cent of what it holds. The original sum comes back when the owner claims it. The interest does not.

That reporting comes from a single news investigation focused largely on one state, not a national audit.

Washington notices

Sam Liccardo and Mike Lawler agree on very little. Liccardo is a Democrat, Lawler a Republican, and together they have introduced the Safeguarding Americans’ Fairly Earned Retirement Act, which would sharply limit when states can take custody of securities, digital assets and investment accounts. Senator Elizabeth Warren has separately written to NAUPA requesting state-by-state data on how these systems work and how the rules are changing.

Whether any of that passes is anyone’s guess. The databases are already open.

Where the records sit

NAUPA’s search hub links out to every participating state’s official database, alongside MissingMoney.com, the multi-state tool covering 49 states, several Canadian provinces and Puerto Rico. Hawaii runs its own system separately.

Property is reported by the company holding it, which means records often sit in a state the owner left years ago.

Old savings bonds now follow the same route. The Treasury retired its Treasury Hunt tool on 30 September 2025, and unredeemed bonds are handled through state unclaimed property offices instead.

A market has grown up around all this. Private recovery firms, legal in most states, charge a percentage to locate money that sits in the same public databases the states publish for free.

A dollar surrendered to a state in 1994 comes back as a dollar. Not a dollar plus thirty years of compounding, not a dollar adjusted for what groceries cost now, just the dollar. Whoever holds it in the meantime is the only party earning anything.

This article is journalism, not financial or legal advice. Unclaimed property rules, dormancy periods and claims procedures vary by state and change over time. Anyone dealing with a substantial claim, an estate, or a disputed entitlement should consult a qualified professional.

A truck wedged under a bridge, its roof peeled back like a sardine can, is such a familiar sight that the Australian city of Melbourne turned one bridge into a folk legend. The Montague Street rail bridge has claimed so many trucks that someone built a website tracking how many days since it was last hit. Bridge strikes are not exotic. They are one of the most repetitive failures in road transport.

Which brings us to a stretch of Central New York in the spring of 2026, and a load that never should have been on the road at the height it was.

What happened over 60 miles of the Thruway

On March 18, 2026, a tractor-trailer hauling an over-height excavator on a flatbed struck multiple overpasses as it traveled west on the Thruway.

The scope is what makes it notable: more than a dozen overpasses hit across roughly 60 miles between Exits 30 and 36.

The driver, 38-year-old Oleksander Tarakanovskyi of North Carolina, was apparently unaware that his load had struck the bridges. After the Thruway Authority alerted State Police, troopers found the truck and stopped it at the Mattydale tandem lot in the town of Salina.

Tarakanovskyi was charged with reckless endangerment in the second degree and issued more than 20 traffic tickets, including violations of federal commercial motor vehicle safety regulations. He was released with an appearance ticket returnable to Salina Town Court on April 8.

The reaction from officials was blunt. Frank G. Hoare, executive director of the Thruway Authority, said, “How a tractor trailer driver could be unaware that his load hit more than a dozen bridges is beyond comprehension.” State Police Major Brian T. Ferrone added, “Reckless, egregious behavior will not be tolerated.”

Why bridge strikes keep happening

The public record does not explain how Tarakanovskyi failed to notice the impacts. But the larger bridge-strike problem often starts before a truck reaches the bridge: with the vehicle’s height and route.

A Network Rail survey in the UK, part of its “Wise Up, Size Up” campaign, found that 43 per cent of lorry drivers admitted they did not measure their vehicle before setting off, while 52 per cent said they did not take low bridges into account. That’s UK data, not a direct explanation for this New York incident, but it shows why height checks and route planning are central to bridge-strike prevention.

Where the safeguards are supposed to catch it

In the US, there is no single federal vehicle-height limit; state limits for standard commercial vehicles commonly run from 13 feet 6 inches to 14 feet. On the New York State Thruway, loads 13 feet 7 inches or higher require a special hauling permit.

Permits, approved routes, escorts and height poles are all meant to move the moment of discovery to before the trip, rather than after a bridge is hit.

Take the King Street Bridge over the Hutchinson River Parkway in Westchester County. It was 

The wider problem has been documented for years. A 2013 City College of New York study found that bridges in the state were experiencing roughly 200 strikes annually at the time, with many concentrated on a much smaller group of repeatedly hit bridges.

A solvable problem that stays unsolved

At a 2018 meeting about bridge strikes on the Hutchinson River Parkway, Westchester County Executive George Latimer captured the exasperation. “This is a solvable problem,” he said, adding, “If government can’t solve a problem like this, then government can’t do anything.”

The engineering measures are familiar: know the vehicle’s height, plan a legal route, use permits and escorts where required, and install detection systems where repeated strikes justify them. The hard part is making those checks work consistently across a large road network.

The 2026 Thruway incident stands out because one over-height load allegedly produced a 60-mile trail of damage before police stopped it. But the underlying failure was not new. Bridge strikes are repetitive precisely because the safeguards depend on measurements, route choices and warnings being acted on before the truck reaches the bridge.

A mother rinsed her baby’s dirty nappy in a bucket and tipped the water into the cesspool outside her front door. Within ten days, more than 500 of her neighbours were dead. If Henry Whitehead’s later reconstruction was right, hers was where it started.

The baby was five months old and lived at 40 Broad Street, Soho, in a district of tenements chopped into cheap rented rooms. Her death, on 2 September 1854, went into the records as diarrhoea rather than cholera, so she never appeared in the tally that made the street famous, as Gavi’s account of the outbreak notes.

Ten minutes’ walk away in Sackville Street lived a physician named John Snow, who had spent five years arguing that cholera travelled in water and getting nowhere. His 1849 essay on the subject was largely ignored by the medical profession. Respectable opinion held that epidemic disease rose off rotting matter as a poisonous vapour, a theory called miasma. Under miasma, the smell was the disease.

The map was made of black bars

Snow got the addresses of the dead from the General Register Office and walked them. He knocked on doors, asked survivors where they drew their water and worked out that the deaths clustered overwhelmingly around one public pump on Broad Street.

Months later he turned that investigation into the map that became famous, marking each known death as a short black bar at the address where it happened. By December he had tracked down 616 deaths, though only 574 could be placed on the map itself, the rest belonging to people who had died away from the district with no address on record. He published it in the second edition of On the Mode of Communication of Cholera in 1855.

He had no germ, no culture and no microscope image worth anything, only addresses.

The strongest evidence came from people who survived

Seventy men worked at the brewery on Broad Street and not one of them died. They drank a daily beer allowance, used a private well and never touched the public pump, per the Science History Institute’s account of the investigation. A workhouse squarely inside the death zone held over 500 people, lost only a handful and had its own supply.

Then there was the widow. A woman in Hampstead, miles to the north, died on 2 September, her visiting niece the day after. Neither had set foot in Soho for years. Snow went up to interview her son and learned she had once lived on Broad Street, liked the taste of the water and kept a servant carting bottles of it north. Her last delivery arrived on 31 August, the night the outbreak began.

Geography was the wrong variable and plumbing was the right one.

The parish agreed and the government did not

On the evening of 7 September, Snow put his case to the Board of Guardians of St James parish. They were sceptical of the theory and impressed by the arithmetic, and the handle was unscrewed the following morning.

Deaths were already falling by then, as Snow himself acknowledged. Thousands had fled the neighbourhood, and the contamination that triggered the outbreak had probably washed through days before.

The national verdict was blunter. England’s General Board of Health reviewed Snow’s theory through its Committee for Scientific Inquiries and rejected it outright: “After careful inquiry we see no reason to adopt this belief.” That committee, as Nigel Paneth and colleagues documented in the American Journal of Public Health, spent roughly a third of its 352-page scientific appendix on barometric pressure, wind direction, cloud cover and ozone levels. One of its own inspectors had handed Snow the Hampstead evidence.

The curate who found the first case

Henry Whitehead, assistant curate of St Luke’s on Berwick Street, had spent the outbreak climbing those stairs with food and last rites. He thought Snow was wrong, and joined the parish inquiry committee partly to clear the pump’s name. Snow gave him a copy of the monograph and he read it and stayed unconvinced, so he went out to disprove it. In April 1855, seven months after the last death, he traced the chain back to the baby at number 40, a case Snow had never counted, as S.P.W. Chave set out in Medical History.

The parish surveyor dug up the well and found the cesspool brickwork rotted through, inches from the well lining.

Whitehead also worked out what taking the handle off achieved. The baby’s father came down with cholera on 8 September, the morning the parish disabled the pump, and his waste would have gone the same way his daughter’s had.

Snow died in 1858, aged 45, with the profession still against him. In Florence that same autumn of 1854, an anatomist named Filippo Pacini had put cholera discharges under a microscope, seen comma-shaped organisms swarming in them and published. Italian medicine believed in bad air too, and Pacini’s finding went unnoticed by Snow, by Robert Koch and by almost everybody else until long after his death. Bacteriologists made it official in 1965, naming the organism Vibrio cholerae Pacini 1854.

Two men landed on the answer in the same year, in two cities, and the medical establishment believed neither of them. The handle came off anyway.

The post A London doctor traced hundreds of cholera deaths in 1854 to one neighborhood water pump and persuaded the parish to remove its handle — months later he mapped the outbreak, years before contaminated water was widely accepted as a cause of cholera appeared first on Space Daily.

For $995 you could buy a decent second-hand lawnmower, a mid-range mattress, or, if a government spreadsheet has a bad day, a piece of Apollo 11 with moon dust still caught in its seams.

That last one happened. In February 2015, an online auction held on behalf of the US Marshals Service listed a white zippered pouch stamped “Lunar Sample Return”. Nancy Lee Carlson of Inverness, Illinois, bid $995 and won. She knew it had flown on something. What she did not know was that it had ridden along on the first crewed landing on the Moon.

How a moon bag ended up in a garage in Kansas

Blame starts with Max Ary, who ran the Kansas Cosmosphere and Space Center in Hutchinson from 1976 to 2002 and was convicted in November 2005 on twelve federal counts, including theft of government property, wire fraud and money laundering. Investigators searching his garage two years earlier had found a box, and the bag was inside it. As documented by The Hutchinson News, Ary was ordered to pay more than $132,000 in restitution for the space artefacts he had taken, a mix of property belonging to NASA and the museum itself. He always maintained he had simply muddled his own collection with theirs.

His forfeited property went to auction to cover the bill. That is where the mix-up happened. Per the Associated Press, government officials later said two lunar bags had been merged into a single entry when their inventory numbers were combined on spreadsheets. One was from Apollo 17. The other had been to the Sea of Tranquility, and nobody caught the difference before the gavel came down.

What the fabric was hiding

Carlson did the sensible thing and posted the pouch to NASA’s Johnson Space Center for authentication.

Terrible idea, as it turned out. Curators tested the cloth, found lunar material embedded in the fibres, and established that the pouch had served as the outer decontamination bag around the first rocks Neil Armstrong scooped up during the Apollo 11 moonwalk. Then NASA kept it, arguing the bag was government property that should be on public display, not sitting in someone’s living room, and asking the Justice Department to reverse the forfeiture.

Carlson sued. Twice, in two states.

The ruling nobody at NASA wanted

In December 2016, Judge J. Thomas Marten of the US District Court for Kansas ruled that Carlson was “a good faith purchaser, in a sale conducted according to law,” as reported by Robert Pearlman at collectSPACE. Marten went out of his way to say NASA had done nothing wrong here, and that the bag only mattered at all because of what NASA’s own people had pulled off in 1969. He also said he had no power to unwind a sale that had already gone through. Space.com later reported that NASA handed the bag back in February 2017.

Sold at Sotheby’s, well short of the estimate

Sotheby’s offered the pouch on 20 July 2017, 48 years to the day after Armstrong used it. NPR put the hammer price at $1.5 million, or $1,812,500 once Sotheby’s premium was added, which sounds enormous until you notice the house had estimated $2 million to $4 million. The buyer stayed anonymous.

Plenty of people thought the sale should never have happened at all. Michelle Hanlon of For All Moonkind, a group campaigning to protect the Apollo landing sites, said in a statement carried by Smithsonian magazine that the bag belonged in a museum where the world could share in the achievement it represents. Carlson told CBS News she decided to sell because she no longer felt it was safe in her home.

The dust went on to have its own career

NASA’s testing had lifted particles off the bag onto carbon tape mounted on aluminium stubs, and the agency held on to them after returning the pouch. collectSPACE reported that Carlson sued again in January 2019, claiming the testing had damaged the bag, dragged down its market value and caused her real distress, and demanding the return of the lunar material itself. That dispute settled out of court, and the samples went to her.

Which is how, in April 2022, five aluminium stubs, each topped with a 10-millimetre disc of carbon tape, came up in a New York saleroom. Bonhams sold them for $504,375, well under a pre-sale estimate of $800,000 to $1.2 million. Bidding opened at $220,000, seven bids came in, and the hammer fell at $400,000. Independent testing found four of the five stubs carried particles matching Armstrong’s first sample.

NASA still holds almost all of the 382 kilograms of rock, dust and core material brought home by the six Apollo landings. Its position on the rest hasn’t shifted in half a century: this material belongs to the public, not to private collectors. That stance holds up fine, right until two rows get merged on a spreadsheet.

Somewhere out there is a collector nobody can name, holding a cloth bag worth more than most houses, backed by a government receipt for $995 confirming the sale was done by the book.

The post The U.S. government accidentally sold an Apollo 11 bag still carrying traces of moon dust for just $995 in 2015 — the Illinois woman who bought it survived a legal fight with NASA, then sold the same bag at Sotheby’s two years later for $1.8 million appeared first on Space Daily.

A sailor burst into a small wooden railway station in the north end of Halifax on the morning of 6 December 1917 and told everyone inside to run.

Vince Coleman, the dispatcher on duty, walked back to his telegraph key instead. As the Maritime Museum of the Atlantic recounts, he was thinking about the overnight passenger train from Saint John, roughly 300 people aboard, due in at 8:55am on a line that ran straight past a burning munitions ship. He tapped out a warning to hold the train, then signed off: “Guess this will be my last message. Good-bye, boys.”

Minutes later the French cargo ship Mont-Blanc, packed with explosives bound for the war in Europe, detonated in Halifax Harbour.

A city with 2,000 dead and no spare hospital beds

Almost every building within half a mile of the water came down, and records held by the Massachusetts State Library put the immediate toll at 1,800 killed, 3,000 seriously wounded and another 10,000 needing medical attention. Later counts settle at close to 2,000 dead.

Halifax was in no position to absorb that. It was a wartime port, and as the medical journal Proto has documented, local hospitals were already carrying soldiers sent home to recover. Doctors worked through the first night and kept going.

Then it started to snow.

Boston did not wait to be invited

News crossed the wires and landed on the desk of Massachusetts governor Samuel McCall around 11am. What he had was fragmentary at best, a few lines about some sort of catastrophe up the coast. Writing in its account of that day, the Massachusetts Historical Society notes that McCall wired back a promise that his state would go the limit, and called an emergency meeting of the Committee of Public Safety.

By 10pm, twelve hours after the blast, a relief train loaded with doctors, nurses and supplies pulled out of Boston. Nobody in Halifax had yet told them what was needed.

A blizzard caught the train en route, hardly a surprise for Maine and New Brunswick in December. It did not turn back. Staff wired ahead for extra supplies while they were still stuck in the drifts, and the Halifax Municipal Archives documents the first American medical train arriving on 8 December, having pushed through snow for most of the trip.

The help kept arriving for years

That first train turned out to be the opening instalment. Author John U. Bacon, speaking to WBUR about his book on the disaster, counted two trains, two ships, 100 doctors, 300 nurses and about a million dollars in supplies, enough to stand up several temporary hospitals.

The medical unit went home on 14 December and formed the Massachusetts-Halifax Relief Committee on the journey back. The same archive shows it raised half a million dollars, refurnished more than 1,800 homes and set aside $25,000 for the care and education of people blinded by flying glass. Halifax named a block of temporary housing the Governor McCall Apartments, on a newly laid-out Massachusetts Avenue.

One tree in 1918, then a gap of fifty-odd years

Nova Scotia sent Boston a Christmas tree the following December as a thank you, and the tradition quietly lapsed.

It came back in 1971, and not purely out of sentiment. As reported by The Signal, the Lunenburg County Christmas Tree Producers Association revived the gift with one eye on the export market for Nova Scotian spruce. The provincial government took the job over a few years later and has handled it ever since, which is how a one-off act of gratitude became a line item.

What it takes to qualify as the tree

Anyone can nominate one. Criteria published by the Government of Nova Scotia ask for a white spruce, red spruce or balsam fir standing 12 to 15 metres, healthy, good colour, medium to heavy density, uniform and symmetrical, and easy to get a truck near. Officials narrow the field before checking their shortlist with Boston.

Boston’s 2025 tree was a 45-foot white spruce nominated by Ronald and Claire Feener of Lunenburg County. It reached the Common by flatbed truck under police escort, the City of Boston confirmed. Mayor Michelle Wu flew up for the cutting and, as CBC News reported, took a turn with the chainsaw herself on a 42-year-old spruce while a certified tree-felling instructor supervised.

That was a year of tariff threats and cross-border sniping, and the tree went south anyway.

Most international goodwill exists as paperwork nobody reads. This one gets scouted for months, felled in front of a crowd, driven hundreds of kilometres and switched on in a public park every December, all because a train once left Boston into a blizzard for a city that had barely had time to explain what was wrong.

The women walked home at night and glowed.

Radium dust settled in their hair and on their coats, so a dial painter leaving the plant in Orange, New Jersey, trailed a faint shimmer down the footpath. Plenty of them thought this was marvellous. They painted their fingernails with it and dabbed it on their teeth before a dance. Nobody in management suggested they stop.

The paint was branded Undark, a mix of radium and zinc sulfide developed by Dr Sabin von Sochocky. In its account of the digitised company files, the National Archives describes how the Radium Luminous Material Corporation opened its Orange factory in 1917, selling the glow to watchmakers and instrument firms. Radium dials were prized in the trenches of the First World War and fashionable everywhere else.

How the paint got into their bones

Brushes were the whole problem.

Camel-hair bristles lose their point after a few strokes, and the numerals on a wristwatch face are minute. So the painters were taught to roll the brush between their lips before each dip. Lip, dip, paint, several hundred times a shift. The Science Museum Group notes that the New Jersey women worked on paper dials with a water-based paint, applied with fine camelhair brushes rather than the metal stylus used elsewhere in the industry. A trace of radium went down the throat with every dial.

Radium behaves chemically like calcium, so the body lodges it in bone and leaves it there, decaying quietly, for a life that just got much shorter.

The doctor who worked it out

Dentists noticed first. From about 1922 they were pulling aching teeth from young women in Orange, finding that pieces of jawbone came away too. A dentist, Theodor Blum, described the condition in 1924 and named it radium jaw.

Harrison Martland, the Newark pathologist who became Essex County’s first medical examiner, took it further. Writing in the Journal of the American Medical Association in 1925, he measured radioactivity in the tissue of dead dial painters and in the exhaled breath of living ones. A retrospective in Brain credits that work with pioneering the measurement of radioactivity inside contaminated human tissue.

U.S. Radium hired its own experts to challenge his findings. Reasonable enough in 1925, when one man’s diagnosis was still just one man’s diagnosis, though the company kept denying any link to radium for another decade.

Five women, one settlement, no admission

Grace Fryer needed two years to find a lawyer who would take her case. Katherine Schaub, Edna Hussman, Quinta McDonald and Albina Larice joined her, and by the first hearing in January 1928 none of the five could lift an arm to swear the oath.

They settled that June for $10,000 each, an annuity of $600 for life and their medical bills covered. The company admitted nothing, and most dial painters received no compensation at all, the National Archives notes. In 1936, a federal court in New Jersey ruled that U.S. Radium had not fraudulently hidden the danger, a decision that pushed surviving claims outside a two-year limitation period and effectively ended them.

What happened in Ottawa

Meanwhile, in Ottawa, Illinois, the Radium Dial Company assured its painters that the Orange trouble had nothing to do with them, since the radium over there was impure. The firm had been medically screening its own workers since 1925 and keeping the results to itself. As History.com documents, Illinois workers lost in court through the mid-1930s, after which the state passed the Illinois Occupational Diseases Act, effective 1936, requiring employers to carry cover for industrial poisoning.

Catherine Donohue led fifteen women in a fresh suit in 1937. By a hearing the following February she weighed around 32 kilograms and had to be carried into the room, and, as Northern Public Radio reported, she arrived with a box of what she said were pieces of her own jawbone. Local papers took to calling the group the society of the living dead, NPR Illinois reports, and their lawyer, Leonard Grossman, took the case for free because his clients had nothing to pay him. Later hearings moved to Donohue’s home, where she testified from a couch because she could no longer travel.

The Illinois Industrial Commission ruled for Donohue in April 1938 and confirmed the award that July. She died on 27 July, three weeks later. Radium Dial fought on regardless. The Illinois Supreme Court threw out the company’s petition to overturn the award in June 1939, and the U.S. Supreme Court declined a further appeal that October, more than a year after Donohue’s death.

That refusal to intervene left the award standing, and with it the principle that an employer could be held liable for a disease that surfaced years, sometimes a decade or more, after the job ended. Grossman’s son, three decades a Department of Labor lawyer, traces a line from those hearings to the federal OSHA Act, which he dates to 1971.

The measurements they left behind

Many surviving painters later volunteered their bodies to researchers at Argonne National Laboratory, whose review of the radium cases sets out how those measurements shaped radiation protection limits for the nuclear age.

Radium-226 has a half-life of roughly 1,600 years, so the women are still faintly radioactive in their graves and will be long after everyone reading this is gone. A surprising amount of modern workplace law rests on that fact. None of them were trying to found a legal doctrine. They wanted someone to pay the dentist.

The post American employers told young women painting luminous watch dials that radium was harmless and instructed them to shape the radioactive brushes with their lips — the lawsuits that followed helped establish that employers could be held financially responsible for harm caused by their work appeared first on Space Daily.

America’s first professionally managed forest finished its first year in the red, and the man running it called that a good result.

The shortfall was $392.40. It sits in a table near the back of Gifford Pinchot’s account of the first year’s work at Biltmore Forest, a slim pamphlet printed in Chicago in 1893 as an exhibit for the World’s Columbian Exposition. Pinchot opened by pointing out that the attempt was the first practical application of forest management in the United States.

What Vanderbilt bought

George Vanderbilt had been assembling land south of Asheville since the late 1880s for a house the size of a small village. The ground came cheap because it was wrecked. As the Special Collections Research Center at NC State University documents, landscape architect Frederick Law Olmsted advised that the soils and terrain would never support a grand park, and suggested growing timber instead.

Pinchot’s survey put the estate at 7,282 acres, a little over half of it woodland. The families who had farmed the land before Vanderbilt bought it cut anything sellable as fuel, fencing or saw-logs, grazed cattle through the young growth, and burned the woods off for pasture. Asheville had been heating itself on those hillsides for years.

Pinchot summed up the condition of much of it in three words: “deplorable in the extreme.”

A card catalogue for a forest

Pinchot arrived on 2 February 1892, aged 26, trained in Europe because there was nowhere in America to train. NCpedia records that Olmsted put his name forward, and that he and Vanderbilt agreed on three objectives: sell timber at a profit, produce a steady yield every year, and leave the forest healthier than it was.

Then he counted. Crews broke the woods into more than 600 sections of about 5.7 acres each, describing every one in shorthand on a postcard-sized card and filing the cards as a catalogue of the whole property. He grouped the forest into 92 numbered compartments bounded by ridges, streams and old wood roads, then set a rotation of 150 years, meaning the second crop would be ready for the axe a century and a half after the first came out. Nobody involved expected to see it.

What the first year’s books showed

Labourers earned between 90 cents and a dollar a day, mules 75 cents.

The forest sold cordwood to the estate brickworks, ties to the railroad and lumber to anyone who wanted it, at open market prices. Expenses ran to $9,911.76. Receipts and stock on hand came to $9,519.36. Pinchot kept his own salary out of the accounts and conceded that supervision costs for fewer than 4,000 acres were far too high, arguing the same effort would have covered ten times the area.

Two findings mattered more than the balance. Large old trees could be dropped out of dense young growth with very little damage to the crop underneath, and the additional cost of careful work over ordinary destructive logging was small enough to be beside the point. Both were arguments about money, the case Pinchot had to make in a country that still treated trained forestry as a European specialty.

The German who built a school

Pinchot left in 1895 and went on to become the first chief of the US Forest Service. His replacement came from Germany. Biltmore’s own history of the estate credits Carl Alwin Schenck with running and expanding the plan over the next 14 years, and founding the Biltmore Forest School in 1898, the country’s first forestry school, which trained more than 300 of America’s earliest professional foresters before closing in 1913.

How a private estate became public land

In 1894 Pinchot came across the Pink Beds, a valley of rhododendron and mountain laurel in Transylvania County, and told Vanderbilt to buy it. That purchase and others became Pisgah Forest, and the holdings eventually stretched to roughly 125,000 acres.

Vanderbilt died in March 1914. Per NCpedia’s history of Pisgah National Forest, his widow Edith offered the federal government 86,700 acres at $5 an acre, around $200,000 below the price the family had asked a year earlier, and completed the sale in 1915. Combined with other purchases made under the Weeks Act, that land became Pisgah National Forest on 17 October 1916, the first national forest created under the act, as the Forest History Society documents.

Congress went further in 1968, setting aside 6,540 acres around the Pink Beds as the Cradle of Forestry in America, a site built around the remains of Schenck’s school.

The slow part of the work was never the trees. Pinchot enlarged his crews carefully, because the men he hired had only ever cut wood one season at a time, and the idea of protecting a crop nobody present would live to harvest had to be taught one foreman at a time. It took. More than half a million acres of North Carolina now run on a principle that began as a line item somebody had to justify to a very rich man.

A wind turbine blade is basically glass fibre set in hardened resin. The fibres give it strength, the resin holds them in place, and the two are bonded so tightly that a blade can survive wind, rain and stress.

That same toughness is the problem once the blade comes down. Thermoset epoxy does not melt back into a workable liquid, and its stable chemical bonds are difficult to break. So retired blades are typically cut into sections and sent to landfill.

That is the waste a group of researchers decided to work with. In a 2026 study published in ACS Applied Engineering Materials, a team at Xi’an Shiyou University, with collaborators at the Beijing Institute of Technology and Monash University, ground old blade material into powder and turned it into a lightweight, sponge-like insulation.

Here is what came out of the lab, and how it stacks up against the size of the problem.

It squashes to a fifth of its thickness and springs back

The most surprising thing about the material is how far you can crush it without wrecking it. The team reports it took a squeeze of over 80 percent and recovered, meaning you can press it down to roughly a fifth of its height and it bounces back. That matters because conventional silica aerogels are famously fragile. They insulate well but can be brittle. A material that can take a squeeze and spring back is far easier to handle and install.

The trick is in the structure. Instead of a solid block, the composite is a network full of tiny connected pores, with the blade powder stiffening a soft, springy scaffold. 

It combined low density with unusually high compressibility

Weight is where the main result sits. The material reached a density of 0.184 grams per cubic centimetre while sustaining more than 80 percent compressive strain. The authors say the composite showed “a superior combination of low bulk density (0.184 g cm–3) and high compressive strain (>80%), outperforming a wide range of reported silica-based or organic aerogels and composites.”

A caution is warranted: that line is the researchers describing their own work, not an outside verdict. “Outperforming” is their framing, and the comparison is against numbers from other published papers rather than a head-to-head test by a neutral lab. The figures themselves are measurable; whether the material performs as well in practice is the kind of thing other labs and larger-scale testing would need to settle.

It holds heat in about as well as ordinary insulation

Being light and squishy would not count for much if heat poured straight through it. It doesn’t. The composite measured a thermal conductivity of 0.068 watts per metre-kelvin, and lower is better here because it means less heat gets across. For comparison, ordinary glass wool building insulation sits around 0.04. So the blade composite is not a record-setting insulator, but it is in a sensible range for the job while remaining highly compressible.

It self-extinguishes instead of feeding a flame

Insulation lives inside walls and roofs, so how it behaves near fire matters. The team reports enhanced flame self-extinguishing capability, meaning it tended to stop burning once the flame source was removed rather than carrying the fire along. Again, this is one lab result on lab samples, though, and real fire-safety ratings require standardised testing. Read it as promising, not certified.

It turns a landfill problem into the raw material

The reason any of this is interesting is the sheer number of blades headed for the ground. Worldwide, the mass of blades expected to be discarded by 2050 may reach about 43 million tonnes. Right now, around 12,000 blades are retired across Europe and the US each year, and they are typically cut up and sent to landfill. A process that takes that same material and makes something useful flips the equation.

As the authors put it, reusing the blade waste “not only helps to reduce environmental burdens and resource waste but also opens up avenues for generating high-performing, useful materials.”

Where this actually sits

This is one study and one set of lab measurements. The chemistry is clever and the numbers look good, but the gap between a lab composite and a pallet of insulation shipped to a building site is wide. The paper doesn’t answer the questions that fill that gap: cost, batch-to-batch consistency, how the material holds up over years inside a wall, and whether grinding and processing old blades at scale actually makes economic sense.

That last question is the real hinge. Something has to make the recycled route cheaper or required before a lab result becomes a real supply chain.

None of that takes away from what the team built. This is a good answer to a narrow question, which is whether hard-to-recycle blade waste can be turned into a useful, light, tough insulating material at all. The evidence here says yes. The bigger question, whether it can be done by the tonne cheaply enough to matter, is still open.

The post In 2025, researchers ground retired wind turbine blades into powder, stirred it into a gel and set it into an insulation composite. The composite combined low density with much greater compressibility than many of the insulating aerogels and composites it was compared with, squashing to a fifth of its thickness without breaking apart. appeared first on Space Daily.

Fourteen adult whooping cranes wintered on the Texas coast in 1941. In the winter of 2024–2025, biologists flying the marshes and tidal flats around Aransas National Wildlife Refuge estimated 557 of them, including at least 41 tawny juveniles, according to the U.S. Fish and Wildlife Service’s survey announcement. The agency’s 2024–2025 whooping crane status report gives the estimate as including 193 adult pairs. It was the first time the agency had estimated the Aransas–Wood Buffalo population above 550 individuals.

The number is an estimate, not a hand tally. Whooping cranes are five feet tall and white enough to read against green cordgrass from a thousand feet up, but they move, they hide behind live oak motts, and no aerial pass catches every bird in every acre. What the Service publishes is a statistical estimate with uncertainty attached, and the 2024–2025 figure of 557 carries a 95% confidence interval of 478.7 to 645.1 birds, with a coefficient of variation of 0.137.

What the January flights measured

The survey work happened in a narrow window. Crews flew a Quest Kodiak over roughly 170,500 acres of primary survey area six separate times between January 22 and January 31, 2025, then covered about 85,250 acres of secondary area twice on February 1 and 2. The underlying Butler et al. survey report says abundance was estimated from the aerial surveys using hierarchical distance sampling, with the confidence interval expressing the uncertainty around that estimate rather than a simple difference between repeated passes.

Inside that estimate, the age and pairing structure matters as much as the total. The survey put the population at 193 adult pairs, with a 95% confidence interval of 167.5 to 221.4, and at least 41 juveniles, birds hatched in summer 2024 and still carrying rusty cinnamon feathering across the head and neck. Recruitment worked out to 8.1 chicks per 100 adults, with an interval of 6.3 to 10.5. Juveniles are the part of the count that cannot simply be carried over from an earlier winter estimate. Each one is a bird that hatched, fledged, and completed a first southbound migration.

The Canadian Wildlife Service reported at least 33 chicks fledged on the northern breeding grounds in summer 2024. The winter estimate of 41 juveniles sits above that. The joint status report says the discrepancy is likely caused by differences in survey methodology and detectability of young between the breeding-ground and wintering-ground surveys; the Butler report also notes that juvenile plumage can become less distinct by late January.

From 14 adults to a 4.33% climb

The 1941 low is the baseline against which the recovery is often described. Service biologist Matthew Butler, lead author on the survey, makes the point plainly in the agency’s announcement: today’s whooping cranes descend from the 14 adults that remained on the Texas coast that year. The species had been reduced to a single wild migratory flock wintering on a strip of Gulf coast marsh, with its northern breeding grounds not identified until later.

Those breeding grounds were in and around Wood Buffalo National Park, roughly 2,500 miles north in Canada. The Aransas–Wood Buffalo flock makes that roughly 2,500-mile migration twice each year, north toward the nesting grounds and south toward the Texas coast, threading the Central Flyway through the Great Plains.

Measured from the winter of 1938–1939 to the winter of 2024–2025, the population has grown at an average rate of 4.33% per year. That figure summarizes the long recovery record; it is an average across eight decades, not a claim that the flock grew at exactly 4.33% every year. Kevin McAbee, the Service’s Whooping Crane Recovery Coordinator, credits the long climb in the announcement to decades of cooperative work across the flyway rather than to any single intervention.

Beyond the survey box

Cranes do not restrict themselves to the polygons drawn on a survey map. During the 2024–2025 effort, observers documented 68 additional whooping cranes outside the designated primary survey area. Those birds are not simply added to 557, and the Service is careful about why. Some may represent birds not otherwise counted; some may have moved in and out of the survey boundary. The overlap is unknown, which is exactly the reason the 68 stays separate from the primary-area estimate.

What the beyond-area observations do suggest is that wintering whooping cranes are using ground beyond the refuge core, a pattern the Service has tracked as the population has grown. The annual survey itself is a cooperative operation, drawing on the Fish and Wildlife Service’s National Wildlife Refuge System Region 2, the Migratory Bird Program and Ecological Services, the Guadalupe-Blanco River Authority in Texas, and the Canadian Wildlife Service.

The recovery record still runs through a very narrow gate. Every one of the estimated 557 birds in the primary survey area in winter 2024–2025, every one of the 193 adult pairs, and every one of the at least 41 juveniles counted after arriving from Wood Buffalo traces back to the tiny remnant flock represented by those 14 adults on the Texas coast in 1941. Eight decades later, the same wild migratory population was being measured again from the air, with six passes over 170,500 acres between January 22 and January 31, 2025.
