ULA’s Vulcan rocket still doesn’t have the Space Force’s seal of approval

11 February 2025 at 15:55

Last October, United Launch Alliance started stacking its third Vulcan rocket on a mobile launch platform in Florida in preparation for a mission for the US Space Force by the end of the year.

That didn't happen, and ULA is still awaiting the Space Force's formal certification of its new rocket, further pushing out delivery schedules for numerous military satellites booked to fly to orbit on the Vulcan launcher.

Now, several months after stacking the next Vulcan rocket, ULA has started taking it apart. First reported by Spaceflight Now, the "de-stacking" will clear ULA's vertical hangar for assembly of an Atlas V rocket—the Vulcan's predecessor—to launch the first batch of operational satellites for Amazon's Kuiper Internet constellation.

22 states sue to block new NIH funding policy—court puts it on hold

10 February 2025 at 21:20

On Friday, the National Institutes of Health (NIH) announced a sudden change to how it handles the indirect costs of research—the money that pays for things like support services and facilities maintenance. These costs help pay universities and research centers to provide the environment and resources all their researchers need to get research done. Previously, these had been set through negotiations with the university and audits of the spending. These averaged roughly 30 percent of the value of the grant itself and would frequently exceed 50 percent.

The NIH announcement set the rate at 15 percent for every campus. The new rate would start today and apply retroactively to existing grants, meaning most research universities are currently finding themselves facing catastrophic budget shortfalls.

Today, a coalition of 22 states filed a suit that seeks to block the new policy, alleging it violated both a long-standing law and a budget rider that Congress had passed in response to a 2017 attempt by Trump to drastically cut indirect costs. The suit seeks to prevent the new policy or its equivalent from being applied—something that Judge Angel Kelley of the District of Massachusetts granted later in the day. While that injunction only applies to research centers located in the states that have joined the suit, a separate suit was filed in the same district by a group of medical organizations, some of them (such as the Association of American Medical Colleges), have members throughout the country. As a result, Judge Kelley issued a separate ruling that extended the injunction to the remaining states.

After Trump killed a report on nature, researchers push ahead with release

10 February 2025 at 19:45

The first-ever National Nature Assessment—which was based on significant public feedback and strove to reveal how nature loss influences climate change and impacts humanity—may still see the light of day after the Trump administration abruptly ended the ambitious project.

Researchers involved told The New York Times that the nature report was "too important to die" and that an "amazingly broad consensus" remains among its mostly volunteer authors, so the expansive report must be completed and released to the public.

The first draft of the report was due on Tuesday, so the bulk of the initial work appears mostly done. Although the webpage for the project has been deleted, an archived version shows that researchers had expected to spend the rest of 2025 seeking external review and edits before releasing the final report in late 2026.

National Institutes of Health radically cuts support to universities

8 February 2025 at 00:17

Grants paid by the federal government have two components. One covers the direct costs of performing the research, paying for salaries, equipment, and consumables like chemicals or enzymes. But the government also pays what are called indirect costs. These go to the universities and research institutes, covering the costs of providing and maintaining the lab space, heat and electricity, administrative and HR functions, and more.

These indirect costs are negotiated with each research institution and average close to 30 percent of the amount awarded for the research. Some institutions see indirect rates as high as half the value of the grant.

On Friday, the National Institutes of Health (NIH) announced that negotiated rates were ending. Every existing grant, and all those funded in the future, will see the indirect cost rate set to just 15 percent. With no warning and no time to adjust to the change in policy, this will prove catastrophic for the budget of nearly every biomedical research institution.

Return of the California Condor

The spring morning is cool and bright in the Sierra de San Pedro Mártir National Park in Baja California, Mexico, as a bird takes to the skies. Its 9.8-foot wingspan casts a looming silhouette against the sunlight; the sound of its flight is like that of a light aircraft cutting through the wind. In this forest thick with trees up to 600 years old lives the southernmost population of the California condor (Gymnogyps californianus), the only one outside the United States. Dozens of the scavenging birds have been reintroduced here, to live and breed once again in the wild.

Their return has been captained for more than 20 years by biologist Juan Vargas Velasco and his partner María Catalina Porras Peña, a couple who long ago moved away from the comforts of the city to endure extreme winters living in a tent or small trailer, to manage the lives of the 48 condors known to fly over Mexican territory. Together—she as coordinator of the California Condor Conservation Program, and he as field manager—they are the guardians of a project whose origins go back to condor recovery efforts that began in the 1980s in the United States, when populations were decimated, mainly from eating the meat of animals shot by hunters’ lead bullets.

In Mexico, the species disappeared even earlier, in the late 1930s. Its historic return—the first captive-bred condors were released into Mexican territory in 2002—is the result of close binational collaboration among zoos and other institutions in the United States and Mexico.

Rocket Report: Another hiccup with SpaceX upper stage; Japan’s H3 starts strong

7 February 2025 at 12:00

Welcome to Edition 7.30 of the Rocket Report! The US government relies on SpaceX for a lot of missions. These include launching national security satellites, putting astronauts on the Moon, and global broadband communications. But there are hurdles—technical and, increasingly, political—on the road ahead. To put it generously, Elon Musk, without whom much of what SpaceX does wouldn't be possible, is one of the most divisive figures in American life today.

Now, a Democratic lawmaker in Congress has introduced a bill that would end federal contracts for special government employees (like Musk), citing conflict-of-interest concerns. The bill will go nowhere with Republicans in control of Congress, but it is enough to make me pause and think. When the Trump era passes and a new administration takes the White House, how will they view Musk? Will there be an appetite to reduce the government's reliance on SpaceX? To answer this question, you must first ask if the government will even have a choice. What if, as is the case in many areas today, there's no viable replacement for the services offered by SpaceX?

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.

White House budget proposal could shatter the National Science Foundation

6 February 2025 at 22:38

Sometime during the next several weeks, the directors of federal agencies will receive a draft version of President Trump's budget request for the coming fiscal year, which begins on October 1. This "passback review" is a standard part of the federal budgeting process which ends in Congress writing a budget and the president signing it into law.

The budget request will be the first of President Trump's second term, and it will offer a clear window into the priorities of his new administration. Although widespread cuts are expected for much of the government's discretionary spending, the outlook for the National Science Foundation appears to be especially grim.

During an emotional all-hands meeting on Tuesday, the agency's assistant director for engineering, Susan Margulies, told agency employees to expect between a quarter and a half of its staff to be laid off within the coming months, E&E News reported.

The UK got rid of coal—where’s it going next?

6 February 2025 at 20:20

With the closure of its last coal-fired power plant, Ratcliffe-on-Soar, on September 30, 2024, the United Kingdom has taken a significant step toward its net-zero goals. It’s no small feat to end the 142-year era of coal-powered electricity in the country that pioneered the Industrial Revolution. Yet the UK's journey away from coal has been remarkably swift, with coal generation plummeting from 40 percent of the electricity mix in 2012 to just two percent in 2019, and finally to zero in 2024.

As of 2023, approximately half of UK electricity generation comes from zero-carbon sources, with natural gas serving as a transitional fuel. The UK aims to cut greenhouse gas emissions by 42 percent to 48 percent by 2027 and achieve net-zero by 2050. The government set a firm target to generate all of its electricity from renewable sources by 2040, emphasizing offshore wind and solar energy as the keys.

What will things look like in the intervening years, which will lead us from today to net-zero? Everyone’s scenario, even when based in serious science, boils down to a guessing game. Yet some things are more certain than others, the most important of these factors being the ones that are on solid footing beneath all of the guesswork.

Parrots struggle when told to do something other than mimic their peers

6 February 2025 at 19:24

There have been many studies on the capability of non-human animals to mimic transitive actions—actions that have a purpose. Hardly any studies have shown that animals are also capable of intransitive actions. Even though intransitive actions have no particular purpose, imitating these non-conscious movements is still thought to help with socialization and strengthen bonds for both animals and humans.

Zoologist Esha Haldar and colleagues from the Comparative Cognition Research group worked with blue-throated macaws, which are critically endangered, at the Loro Parque Fundación in Tenerife. They trained the macaws to perform two intransitive actions, then set up a conflict: Two neighboring macaws were asked to do different actions.

What Haldar and her team found was that individual birds were more likely to perform the same intransitive action as a bird next to them, no matter what they’d been asked to do. This could mean that macaws possess mirror neurons, the same neurons that, in humans, fire when we are watching intransitive movements and cause us to imitate them (at least if these neurons function the way some think they do).

Don’t panic, but an asteroid has a 1.9% chance of hitting Earth in 2032

6 February 2025 at 17:00

Something in the sky captured the attention of astronomers in the final days of 2024. A telescope in Chile scanning the night sky detected a faint point of light, and it didn't correspond to any of the thousands of known stars, comets, and asteroids in astronomers' all-sky catalog.

The detection on December 27 came from one of a network of telescopes managed by the Asteroid Terrestrial-impact Last Alert System (ATLAS), a NASA-funded project to provide warning of asteroids on a collision course with Earth.

Within a few days, scientists gathered enough information on the asteroid—officially designated 2024 YR4—to determine that its orbit will bring it quite close to Earth in 2028, and then again in 2032. Astronomers ruled out any chance of an impact with Earth in 2028, but there's a small chance the asteroid might hit our planet on December 22, 2032.

Quantum teleportation used to distribute a calculation

5 February 2025 at 20:42

Performing complex algorithms on quantum computers will eventually require access to tens of thousands of hardware qubits. For most of the technologies being developed, this creates a problem: It's difficult to create hardware that can hold that many qubits. As a result, people are looking at various ideas of how we might link processors together in order to have them function as a single computational unit (a challenge that has obviously been solved for classical computers).

In today's issue of Nature, a team at Oxford University describes using quantum teleportation to link two pieces of quantum hardware that were located about 2 meters apart, meaning they could easily have been in different rooms entirely. Once linked, the two pieces of hardware could be treated as a single quantum computer, allowing simple algorithms to be performed that involved operations on both sides of the 2-meter gap.

Quantum teleportation is... different

Our idea of teleportation has been heavily shaped by Star Trek, where people disappear from one location while simultaneously appearing elsewhere. Quantum teleportation doesn't work like that. Instead, you need to pre-position quantum objects at both the source and receiving ends of the teleport and entangle them. Once that's done, it's possible to perform a series of actions that force the recipient to adopt the quantum state of the source. The process of performing this teleportation involves a measurement of the source object, which destroys its quantum state even as it appears at the distant site, so it does share that feature with the popular conception of teleportation.

Scientists found a faster way to brew sour beer—with peas

5 February 2025 at 13:00

Do you long for that tart fruity flavor of a sour beer but wish the complicated brewing process were faster? Norwegian scientists might have the answer: field peas, as well as beans and lentils. According to a new paper published in the Journal of Agricultural and Food Chemistry, experimental beers made with the sugars found in these foods had similar flavor profiles to your average Belgian-style sour beer, yet the brewing process was shorter with simpler steps.

“Sour beer is the beer enthusiast’s alternative to champagne," said co-author Bjørge Westereng of the Norwegian University of Life Science. "By using sugars derived from peas that yeast cannot metabolize, we promote the growth of bacteria essential for producing sour beer.”

As previously reported, sour beer has been around for centuries and has become a favorite with craft brewers in recent years, although the brewing process can be both unpredictable and time-consuming. Brewers of standard beer carefully control the strains of yeast they use, taking care to ensure other microbes don't sneak into the mix, lest they alter the flavor during fermentation.

Gecko feet inspire anti-slip shoe soles

4 February 2025 at 16:07

Gecko feet have inspired many intriguing applications, including a sticky tape, adhesives, a "stickybot" climbing robot, and even a strapless bra design. Now, scientists have developed a new kind of anti-slip polymer that sticks to ice, inspired by the humble gecko. Incorporating these polymers into shoe soles could reduce the number of human slip-and-fall injuries, according to a paper published in the journal ACS Applied Materials & Interfaces.

As previously reported, geckos are known for being expert climbers; they're able to stick to any surface thanks to tiny hair-like structures on the bottoms of their feet. Those microscopic hairs are called setae, each of which splits off into hundreds of even smaller bristles called spatulae. It has long been known that at microscopic size scales, the so-called van der Waals forces—the attractive and repulsive forces between two dipole molecules—become significant.

Essentially, the tufts of tiny hairs on gecko feet get so close to the contours in walls and ceilings that electrons from the gecko hair molecules and electrons from the wall molecules interact with each other and create an electromagnetic attraction. That's what enables geckos to climb smooth surfaces like glass effortlessly. Spiders, cockroaches, beetles, bats, tree frogs, and lizards all have varying-sized sticky footpads that use these same forces.

Boeing has now lost $2B on Starliner, but still silent on future plans

4 February 2025 at 13:44

Boeing announced Monday it lost $523 million on the Starliner crew capsule program last year, putting the aerospace company $2 billion in the red on its NASA commercial crew contract since late 2019.

The updated numbers are included in a quarterly filing with the Securities and Exchange Commission. "Risk remains that we may record additional losses in future periods," Boeing wrote in the filing.

In 2014, NASA picked Boeing and SpaceX to develop and certify two commercial crew transporter vehicles. Like SpaceX, Boeing's contract, now worth up to $4.6 billion, is structured as a fixed-price deal, meaning the contractor is on the hook to pay for cost overruns that go over NASA's financial commitment.

Bonobos recognize when humans are ignorant, try to help

3 February 2025 at 22:28

A lot of human society requires what's called a "theory of mind"—the ability to infer the mental state of another person and adjust our actions based on what we expect they know and are thinking. We don't always get this right—it's easy to get confused about what someone else might be thinking—but we still rely on it for everything from navigating complicated social situations to avoiding bumping into people on the street.

There's some mixed evidence that other animals have a limited theory of mind, but there are alternate interpretations for most of it. So two researchers at Johns Hopkins, Luke Townrow and Christopher Krupenye, came up with a way of testing whether some of our closest living relatives, the bonobos, could infer the state of mind of a human they were cooperating with. The work clearly showed that the bonobos could tell when their human partner was ignorant.

Now you see it...

The experimental approach is quite simple and involves a setup familiar to street hustlers: a set of three cups, with a treat placed under one of them. Except in this case, there's no sleight-of-hand in that the chimp can watch as one experimenter places the treat under a cup, and all of the cups remain stationary throughout the experiment.

Let us spray: River dolphins launch pee streams into air

3 February 2025 at 20:14

According to Amazonian folklore, the area's male river dolphins are shapeshifters (encantade), transforming at night into handsome young men who seduce and impregnate human women. The legend's origins may lie in the fact that dolphins have rather human-like genitalia. A group of Canadian biologists didn't spot any suspicious shapeshifting behavior over the four years they spent monitoring a dolphin population in central Brazil, but they did document 36 cases of another human-like behavior: what appears to be some sort of cetacean pissing contest.

Specifically, the male dolphins rolled over onto their backs, displayed their male members, and launched a stream of urine as high as 3 feet into the air. This usually occurred when other males were around, who seemed fascinated in turn by the arching streams of pee, even chasing after them with their snouts. It's possibly a form of chemical sensory communication and not merely a need to relieve themselves, according to the biologists, who described their findings in a paper published in the journal Behavioral Processes. As co-author Claryana Araújo-Wang of CetAsia Research Group in Ontario, Canada, told New Scientist, “We were really shocked, as it was something we had never seen before.”

Spraying urine is a common behavior in many animal species, used to mark territory, defend against predators, communicate with other members of one's species, or as a means of mate selection since it has been suggested that the chemicals in the urine carry useful information about physical health or social dominance.

Greenland’s glaciers are falling apart faster than expected

A new large-scale study of crevasses on the Greenland Ice Sheet shows that those cracks are widening faster as the climate warms, which is likely to speed ice loss and global sea level rise.

Crevasses are wedge-shaped fractures and cracks that open in glaciers where the ice begins to flow faster. They can grow to more than 300 feet wide, thousands of feet long, and hundreds of feet deep. Water from melting snow on the surface can flow through crevasses all the way to the base of the ice, joining with other hidden streams to form a vast drainage system that affects how fast glaciers and ice sheets flow.

The study found that crevasses are expanding more quickly than previously detected, and somewhere between 50 and 90 percent of the water flowing through the Greenland Ice Sheet goes through crevasses, which can warm deeply submerged portions of the glacier and increase lubrication between the base of the ice sheet and the bedrock it flows over. Both those mechanisms can accelerate the flow of the ice itself, said Thomas Chudley, a glaciologist at Durham University in the United Kingdom, who is lead author of the new study.

It seems the FAA office overseeing SpaceX’s Starship probe still has some bite

1 February 2025 at 21:05

The seventh test flight of SpaceX's gigantic Starship rocket came to a disappointing end a little more than two weeks ago. The in-flight failure of the rocket's upper stage, or ship, about eight minutes after launch on January 16 rained debris over the Turks and Caicos Islands and the Atlantic Ocean.

Amateur videos recorded from land, sea, and air showed fiery debris trails streaming overhead at twilight, appearing like a fireworks display gone wrong. Within hours, posts on social media showed small pieces of debris recovered by residents and tourists in the Turks and Caicos. Most of these items were modest in size, and many appeared to be chunks of tiles from Starship's heat shield.

Unsurprisingly, the Federal Aviation Administration grounded Starship and ordered an investigation into the accident on the day after the launch. This decision came three days before the inauguration of President Donald Trump. Elon Musk's close relationship with Trump, coupled with the new administration's appetite for cutting regulations and reducing the size of government, led some industry watchers to question whether Musk's influence might change the FAA's stance on SpaceX.

To help AIs understand the world, researchers put them in a robot

1 February 2025 at 12:05

Large language models like ChatGPT display conversational skills, but the problem is they don’t really understand the words they use. They are primarily systems that interact with data obtained from the real world but not the real world itself. Humans, on the other hand, associate language with experiences. We know what the word “hot” means because we’ve been burned at some point in our lives.

Is it possible to get an AI to achieve a human-like understanding of language? A team of researchers at the Okinawa Institute of Science and Technology built a brain-inspired AI model comprising multiple neural networks. The AI was very limited—it could learn a total of just five nouns and eight verbs. But their AI seems to have learned more than just those words; it learned the concepts behind them.

Babysitting robotic arms

“The inspiration for our model came from developmental psychology. We tried to emulate how infants learn and develop language,” says Prasanna Vijayaraghavan, a researcher at the Okinawa Institute of Science and Technology and the lead author of the study.
