A tropical fruit best known for its sweet flavor may also help tackle one of the world’s most common nutritional problems. Regularly drinking guava juice could be a simple and affordable way to help reduce the risk of anemia among women in low and middle income countries, according to a review of existing research published [...]A new evolutionary analysis suggests that modern blood and immune cells may preserve a 700-million-year legacy inherited from ancient single-celled ancestors. Long before humans, dinosaurs, or even fish existed, ancient single-celled organisms may have already carried the genetic blueprint for one of the body’s most important systems: blood. A new study from Kyoto University suggests [...]Researchers say the isolated white dwarfs Gandalf and Moon-Sized define a new class of stellar remnant because they share five traits, including X-ray emission. Across the immense scale of the Universe, a single unusual object can prompt astronomers to look for others like it, sometimes leading to the recognition of an entirely new class of [...]Parents in rural, low-income households who maintained strong family routines reported fewer behavior problems and ADHD symptoms in their children. Starting elementary school is an important step for children, but the shift can be challenging. Some children experience separation anxiety, while others have difficulty adjusting to classroom rules and daily school structure. A Penn State-led [...]GPS is commonly treated as a way to find a route or track a delivery. In critical infrastructure, its quieter function is often more consequential: it distributes precise time that helps far-flung systems agree on when something happened. That shared time base supports cellular and broadband networks, parts of the electric grid, and regulated timekeeping […]

Researchers in Switzerland claim to have built a perfect random number generator from two quantum superconducting chips, a 30-meter-long pipe, and some software. The resulting device could be used to generate cryptographic keys, or to offer a “public randomness service” for lotteries or blockchain applications, they say.
They’re not the first to make the claim.
Many sources of randomness are biased. For example, coins or dice tend to favor one side. “Even modern random number generators, which are based on quantum mechanical effects like the reflection of photons from beam splitters, are not entirely immune to such a systematic error or ‘bias’,” said Andreas Wallraff, one of the leaders of the research team at ETH Zurich.
Similar biases can be found in purely software-based pseudo-random number generators. This has led to security problems in IoT devices and WhatsApp, among other applications.
To get around that, the researchers set up of two supercomputing chips, each representing one qubit, cooled to near absolute zero. The chips are connected by a 30-meter-long microwave guide, similarly cooled, and the microwave photons flying between them create a situation of quantum entanglement.
The results produced by this process are then transformed via a special algorithm to generate perfect randomness. “The resulting sequence of zeros and ones is now really perfectly random, and we can even certify that,” said Renato Renner, the other team leader. “The technical improvements allowed us to create random numbers that will remain perfectly random for all eternity.”
The team published their results this week in an article entitled “Experimental randomness amplification” in Nature.

Cape Canaveral Space Force Station (CCSFS) in Florida resumed operations Friday following the explosion of Blue Origin’s New Glenn rocket during a test Thursday night. Space Launch Delta 45 (SLD 45), which manages the U.S. Space Force’s Eastern Range and oversees all East Coast rocket and missile launches, said Friday that a SpaceX Falcon 9 rocket deployedContinue reading "New Glenn explosion: what it means for Blue Origin and SpaceX"

After completing what it said was a “thorough assessment,” the FAA on Wednesday ordered SpaceX to investigate anomalies that its Super Heavy booster experienced during the 12th test flight of its behemoth Starship rocket. The aviation regulator on Tuesday was ambiguous about whether an investigation would be required into Starship Flight 12, which launched Friday evening fromContinue reading "FAA grounds SpaceX Starship after V3 debut"

Welcome to Edition 8.43 of the Rocket Report! A disclaimer: No one yet fully appreciates the ramifications of Blue Origin's New Glenn rocket explosion Thursday night on its launch pad at Cape Canaveral, Florida. What we know as of this writing is that much of Blue's sole orbital-class launch pad has been destroyed, and the New Glenn rocket will be grounded for an extended period of time. It is too soon for any hot takes, at least until the Sun rises at the Cape on Friday morning. One thing I am sure of is that we will be writing about this event for weeks, months, and years to come.
As always, we welcome reader submissions. If you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.
Charting China's contribution to space junk. There's a problem with the drastic uptick in Chinese space launches over the last decade. China appears to be ignoring long-established norms about disposing of the upper stages of rockets, Ars reports. These are the parts of the vehicle that separate from the first stage of a rocket and push a satellite or spacecraft into orbit. In the early decades of spaceflight, launch operators routinely left upper stages in orbit after they released their payloads. But most launch companies today reserve enough propellant in their rockets to remove them from orbit to avoid the risk of spent upper stages becoming a source of space debris. But China is not following this trend. There has been striking growth in China’s rocket body mass. In the past five years, the mass of Chinese rocket bodies in long-lived orbits has risen from less than 100 metric tons to 252, according to a new analysis by Space Domain Awareness expert Jim Shell.

On Thursday evening, Blue Origin attempted to test fire its massive New Glenn rocket at its Florida launch site, but something went very wrong after engine ignition. The super heavy lift rocket exploded in spectacular and disastrous fashion.
The static fire test was being filmed by NASASpaceflight.com on its Space Coast Live feed, which captured video of the conflagration that followed the destruction of the booster. The first stage of New Glenn, fueled with methane, produced a massive fireball above the launch site along the Florida coast, LC-36A. It is possibly the most dramatic and powerful rocket explosion since the Soviet Union's N1 rocket was destroyed during a launch attempt in 1969.

Tom Akers and Joe Tanner are finally in the same class.
The two veteran space shuttle crew members were inducted into the US Astronaut Hall of Fame together on May 16. They could also have been in the same NASA astronaut selection group, too, had history played out a little differently.
In 1984, Tanner reported to the Johnson Space Center (JSC) to fly as an instructor pilot and then applied for the next class of astronaut candidates.

Humans do not just visit space; they live there, but a major part of that is coming to an end. The platform that made the longest continuous human presence in space possible is becoming history.
With NASA and its partners beginning preparations for the destructive end of the International Space Station (ISS) as soon as 2030, those who collect, curate, and study the station are now asking how to preserve the historic and culturally significant artifact, given that it is far too large and complex to keep intact.
The Smithsonian National Air and Space Museum on Thursday hosted a three-part panel discussion, bringing together space program officials, museum curators, an archeologist, and an astronaut to begin answering the why, what, and how the ISS might be saved. The sessions were part of the American Institute of Aeronautics and Astronautics' (AIAA) ASCEND conference in Washington, DC.

NASA Administrator Jared Isaacman sent a long email to employees on Friday morning outlining several structural changes that are intended to make the sprawling agency more efficient and allow it to better accomplish major goals, such as returning to the Moon and building a base there.
"I believe it is imperative to concentrate resources towards the highest priority objectives in the National Space Policy and liberate the best and brightest from needless bureaucracy and obstacles that impede progress," Isaacman wrote in his 3,000-word letter.
Isaacman's message stressed that no one at NASA will lose their jobs, and no field centers will be closed as part of these changes. Rather, the overall intent is to improve operational efficiency and focus on the agency's core missions. Isaacman laid these out as: execute on the Artemis Program to return humans to the Moon; build an enduring Moon Base; develop a "Space Reactor Office" to get America underway on nuclear power in space; ignite an economy in low-Earth orbit; and build more X-planes and launch more science missions.

NASA confirmed Thursday that the Russian segment of the International Space Station has begun leaking atmosphere into space again. It's an old problem that NASA recently hoped was resolved.
For more than half a decade, engineers from Roscosmos and NASA have been tracking the leak rate from a small Russian module attached to the space station that leads to a docking port. The source of these leaks, microscopic structural cracks, have been difficult to find and address.
In January, NASA said that after multiple inspections and sealant applications, the pressure inside this segment, known as the PrK module, had reached a "stable configuration." The PrK module is essentially a transfer tunnel attached to the Zvezda Service Module on the Russian segment of the space station.

BHP has continued to spend hundreds of millions of dollars buying diesel trucks in the Pilbara despite internal documents suggesting it would increase emissions and be “misaligned” with its decarbonisation goals.
The mining giant is Australia’s biggest consumer of diesel and trucks are its biggest single source of diesel emissions. Replacing the fleet with battery-electric trucks is considered a critical step in the multinational’s efforts to decarbonise.
