UK research agency backs drone-based internet service experiment with lasers, microwaves, and gravity waves used for wireless power — Britain invests $94 million into Starlink alternative

While China and Russia rush to build a SpaceX competitor, the UK is taking another route by developing an alternative to satellite internet that relies mostly on aircraft. Its Advanced Research and Invention Agency (ARIA) is funding 18 projects aimed at building aircraft that will deliver wireless communications to areas in the UK and the rest of the world that are not served by terrestrial networks. According to The Register, the program, called Enduring Atmospheric Platforms, aims to have a unit with a 300-watt communications payload aloft and holding station for a week.

These units are called high-altitude pseudo-satellites (HAPS), with ARIA allocating $94 million over three and a half years for these projects. There are three technical areas in focus at the moment: TA1, which aims to develop the underlying technologies; TA2, which looks into the integration and testing of the developed systems; and TA3, which will concentrate on actual deployment.

Two startups have proposed multiple drone systems that will cover the entire United Kingdom — Carousel, by Menapia, wants to build a constellation that can hover at altitudes of up to 12 miles, while Enduring Drone Networks, by VFP Aerospace, proposes a relay of units that automatically fly back to their ground station for charging and servicing, with a cost of about $67,000 per drone.

Two other proposals suggest wireless power — one is Scalable Laser Ltd, which is working on a laser-based technology that pairs high-power laser diodes on the ground with advanced photovoltaic receivers in the air. On the other hand, Space Solar Engineering Ltd wants to use radio frequencies, like microwave, to deliver power to airborne units. There’s also a more novel approach from the University of Bath, which plans to use atmospheric gravity waves — using the upward movement of air caused by weather fronts and geographical features and the subsequent pull of gravity that brings it back down — to extend the range and endurance of HAPS aircraft.

"This research expands the UK's leadership in high-altitude platforms to become the place where this industry is designed, built, and scaled," says ARIA program director Rico Chandra. "Getting there means backing bold ideas, from fixed-wing solar aircraft to designs nobody predicted, including aircraft that fly on spinning wings instead of propellers."

Rescuers race against time as fires ravage orangutan habitat inside Indonesian oil palm concession

JAKARTA — Conservationists are racing to rescue orangutans from a fire-ravaged peat-swamp forest inside an RSPO-certified oil palm concession in West Kalimantan, with smoke still rising and the ground remaining dangerously hot. The 657-hectare (1,623-acre) forest, designated as a High Conservation Value (HCV) area inside PT Kayung Agro Lestari (KAL), is home to around 60 Bornean orangutans (Pongo pygmaeus), one of three orangutan species in the world and the only one found on the island of Borneo, according to conservationists. The forest was also used in October 2015 to release four orangutans rescued by the Yayasan International Animal Rescue Indonesia (YIARI), a Borneo-based NGO working to establish and maintain sustainable orangutan populations. Nearly 11 years after four orangutans were released there, the peat-swamp forest that provided their habitat has itself been almost completely affected by fire, according to satellite analysis by technology consultancy TheTreeMap. This animation shows the progression of fire within and around the PT Kayung Agro Lestari concession in Ketapang (yellow lines), West Kalimantan, between 8 August and 12 September 2026. The sequence shows how fires progressively burned the HCV forests (turning from dark green to dark red) over the course of several weeks. Image courtesy of TheTreeMap/Nusantara Atlas. The analysis indicates that one of the major fires began on Aug. 8 along a canal at the edge of the oil palm plantation in Ketapang district, before spreading westward into the HCV forest. A team of conservationists, including staff from YIARI, is now trying to rescue orangutans still…This article was originally published on Mongabay

The answers to today's Strands, game #928, are…

  • PEANUTS
  • ZIPPY
  • MUTTS
  • PICKLES
  • ZITS
  • BLONDIE
  • SPANGRAM: THEFUNNYPAGES
  • My rating: Hard
  • My score: 3 hints

After missing out on getting an easy Spangram-first yesterday I was on a mission to spot it today and it ended up being far easier than I thought.

I was unsure exactly what the theme meant, but seeing the word 'funny' in the middle of the board and then the word 'the' in the top-left-hand corner helped me connect THEFUNNYPAGES.

This, though, was where my good fortune ended, as I needed three hints to find all of the comic strip names, being familiar with only Peanuts.

Comic strips were less of a big deal in the UK, where I grew up, although the cartoon strips on the back page along with the TV listings section were the only parts of the newspaper I read as a kid. Ours, though, were the adventures of a world-weary viking called Hägar.

NYT Connections today (game #1194) - the answers

NYT Connections answers for game 1194 on a purple background

(Image credit: New York Times)

The answers to today's Connections, game #1194, are…

  • YELLOW: ELASTICITY: BOUNCE, FLEXIBILITY, GIVE, SPRING
  • GREEN: THINGS THAT ARE UNDERGROUND: MINE SHAFT, SEWER LINE, SUBWAY STATION, WELL
  • BLUE: HUGH JACKMAN MOVIES, WITH "THE": FOUNTAIN, PRESTIGE, SHEEP DETECTIVES, WOLVERINE
  • PURPLE: LOVE ____: HANDLES, LANGUAGE, TAP, TRIANGLE
  • My rating: Hard
  • My score: 2 mistakes

My first mistake could have been a group of ways to access water — SPRING, TAP, WELL and FOUNTAIN — but drew a complete blank.

Thinking of a different meaning for SPRING helped me find the other words describing ELASTICITY, but I flopped again, adding TAP instead of WELL to the group that became THINGS THAT ARE UNDERGROUND.

Finally, I did not know that I was collecting HUGH JACKMAN MOVIES, WITH “THE” but I knew that PRESTIGE, SHEEP DETECTIVES and WOLVERINE were all films and took a gamble that FOUNTAIN was too.

Yesterday's NYT Connections answers (Wednesday, September 16, 2026, game #1193)

  • YELLOW: ENDING IN METAL ELEMENTS: LATIN, LONG JOHN SILVER, MARIGOLD, STEAM IRON
  • GREEN: STARTING WITH U.S. COINS: DIMENSION, NICKELODEON, PENNYWISE, QUARTERBACK
  • BLUE: POETS' MIDDLE NAMES: BARRETT, CARLOS, ST. VINCENT, WADSWORTH
  • PURPLE: SAUSAGES PLUS A LETTER: BORAT, CLINK, FRANK-N-FURTER, WIDENER

What is NYT Connections?

NYT Connections is one of several increasingly popular word games made by the New York Times. It challenges you to find groups of four items that share something in common, and each group has a different difficulty level: green is easy, yellow a little harder, blue often quite tough and purple usually very difficult.

On the plus side, you don't technically need to solve the final one, as you'll be able to answer that one by a process of elimination. What's more, you can make up to four mistakes, which gives you a little bit of breathing room.

It's a little more involved than something like Wordle, however, and there are plenty of opportunities for the game to trip you up with tricks. For instance, watch out for homophones and other word games that could disguise the answers.

It's playable for free via the NYT Games site on desktop or mobile.

Xcode 27.2 Is Out, but 27.1 Is Not, Which Means Developers Still Can’t Get Started on Duo-Adapted Apps

A note flagged “Important” atop the Xcode 27.2 release notes:

The iOS SDK and simulator support for iPhone Duo will be available later this month in an upcoming release of Xcode 27.1.

Adapting apps for the Duo is not just a simple “recompile with the new SDK”. It’s different. For just about all apps it’s going to be a significant amount of work, and for some apps it’s going to be a lot of work. But without Xcode 27.1, developers cannot get started. Developers wanted this SDK a week ago. And when day one preorder buyers start using their Duos on October 23, they’re going to wish Apple had shipped this SDK last week too.

California may gut state net neutrality law to comply with Trump admin demand

California is on the verge of accepting $1.86 billion in federal broadband grant funds, despite the Trump administration telling states they cannot enforce net neutrality rules on any Internet service provider that gets a piece of the grant money.

When the Trump administration overhauled the $42 billion Broadband Equity, Access, and Deployment (BEAD) program last year, it ruled that states must agree not to enforce any rate regulation or net neutrality rule on ISPs that receive funding. This is particularly problematic for California, which previously won a yearslong court battle to defend its state net neutrality law.

Similar to federal net neutrality rules repealed during the first Trump administration, California's law prohibits ISPs from blocking or throttling lawful traffic and says ISPs may not require fees from websites or online services to deliver or prioritize their traffic to Internet users. While the first Trump administration lost its attempt to preempt state net neutrality laws, the second Trump administration is trying to achieve a similar result by making federal broadband money conditional on whether states agree not to enforce net neutrality.

Researchers swap in human brain cells for a mouse's cortex

In recent years, there has been a lot of excitement about the potential for studying human diseases in what are called "organoids." These small patches of tissue, formed using stem cells, appear to produce many of the same cell types and at least some of the structures normally formed in actual organs, and thus can provide a better model for diseases that rely on the sometimes complex interactions among multiple specialized cell types that are a feature of the human body.

But even the most sophisticated organoids lack a lot of the features of a real human body. This is especially true for brain organoids, which don't form any of the connections with specialized brain structures needed to behave "normally." On Wednesday, a research group at Stanford University described a possible way to study brain organoids in a somewhat more natural context: They genetically wiped out a large portion of the mouse brain and replaced it with human brain organoid cells.

The replacements

Organoids, because they adopt a three-dimensional tissue structure and consist of various specialized cells, provide a much better model for an intact tissue than simply having a bunch of disassociated cells lying flat on a culture dish. But they still have a lot of limitations—they're not hooked up to a circulatory system that allows the liver to process chemicals the organoid produces and don't have immune cells moving through them, to give just a couple of examples.
