An anonymous reader quotes a report from Popular Science: On March 2, Firefly Aerospace's Blue Ghost made history, becoming the first commercial lunar lander to successfully touchdown on the moon's surface. The groundbreaking lander is wasting no time in getting to work. According to NASA, the joint public-private mission has already successfully demonstrated the ability to use Earth-based GPS signals on the lunar surface, marking a major step ahead of future Artemis missions. Accurate and reliable navigation will be vital for future astronauts as they travel across the moon, but traditional GPS tools aren't much good when you're around 225,000 miles from Earth. One solution could be transmitting data from the Global Navigation Satellite System (GNSS) to the lunar surface in order to autonomously measure time, velocity, and position. That's what mission engineers from NASA and the Italian Space Agency hoped to demonstrate through the Lunar GNSS Receiver Experiment (LuGRE), one of the 10 projects packed aboard Blue Ghost. [...]

"On Earth we can use GNSS signals to navigate in everything from smartphones to airplanes," Kevin Coggins, deputy associate administrator for NASA's SCaN (Space Communications and Navigation) Program, said in a statement. "Now, LuGRE shows us that we can successfully acquire and track GNSS signals at the Moon." LuGRE relied on two GNSS constellations, GPS and Galileo, which triangulate positioning based on dozens of medium Earth orbit satellites that provide real-time tracking data. It performed its navigational fix at approximately 2 a.m. EST on March 3, while about 225,000 miles from Earth. Blue Ghost's LuGRE system will continue collecting information over the next two weeks almost continuously while the lander's other tools begin their own experiments.

Australian company Cortical Labs has launched the CL1, the world's first commercial "biological computer" that merges human brain cells with silicon hardware to form adaptable, energy-efficient neural networks. New Atlas reports: Known as a Synthetic Biological Intelligence (SBI), Cortical's CL1 system was officially launched in Barcelona on March 2, 2025, and is expected to be a game-changer for science and medical research. The human-cell neural networks that form on the silicon "chip" are essentially an ever-evolving organic computer, and the engineers behind it say it learns so quickly and flexibly that it completely outpaces the silicon-based AI chips used to train existing large language models (LLMs) like ChatGPT.

"Today is the culmination of a vision that has powered Cortical Labs for almost six years," said Cortical founder and CEO Dr Hon Weng Chong. "We've enjoyed a series of critical breakthroughs in recent years, most notably our research in the journal Neuron, through which cultures were embedded in a simulated game-world, and were provided with electrophysiological stimulation and recording to mimic the arcade game Pong. However, our long-term mission has been to democratize this technology, making it accessible to researchers without specialized hardware and software. The CL1 is the realization of that mission." He added that while this is a groundbreaking step forward, the full extent of the SBI system won't be seen until it's in users' hands.

"We're offering 'Wetware-as-a-Service' (WaaS)," he added -- customers will be able to buy the CL-1 biocomputer outright, or simply buy time on the chips, accessing them remotely to work with the cultured cell technology via the cloud. "This platform will enable the millions of researchers, innovators and big-thinkers around the world to turn the CL1's potential into tangible, real-word impact. We'll provide the platform and support for them to invest in R&D and drive new breakthroughs and research." These remarkable brain-cell biocomputers could revolutionize everything from drug discovery and clinical testing to how robotic "intelligence" is built, allowing unlimited personalization depending on need. The CL1, which will be widely available in the second half of 2025, is an enormous achievement for Cortical -- and as New Atlas saw recently with a visit to the company's Melbourne headquarters -- the potential here is much more far-reaching than Pong.

EmagGeek shares a report: Scientists have genetically engineered mice with some key characteristics of an extinct animal that was far larger -- the woolly mammoth. This "woolly mouse" marks an important step toward achieving the researchers' ultimate goal -- bringing a woolly mammoth-like creature back from extinction, they say.

"For us, it's an incredibly big deal," says Beth Shapiro, chief science officer at Colossal Biosciences, a Dallas company trying to resurrect the woolly mammoth and other extinct species. The company announced the creation of the woolly mice Tuesday in a news release and posted a scientific paper online detailing the achievement. Scientists implanted genetically modified embryos in female lab mice that gave birth to the first of the woolly pups in October.

My editorial: One has to wonder why it is necessary or even a great idea to bring back species that nature long ago determined were a failure.

AmiMoJo shares a report: Europe's biggest battery storage project has entered commercial operation in Scotland [alternative source], promising to soak up surplus wind power and prevent turbines being paid to switch off.

Zenobe said the first phase of its project at Blackhillock, between Inverness and Aberdeen, was now live with capacity to store enough power to supply 200 megawatts of electricity for two hours. It is due to be expanded to 300 megawatts by next year, enough to supply 3.1 million homes, more than every household in Scotland.

The government's Clean Power 2030 action plan sets a target capacity of up to 27 gigawatts of batteries by 2030, a sixfold increase from the 4.5 gigawatts installed today. This huge expansion is seen as critical as Britain builds more renewable wind and solar power, since batteries can store surplus generation for use when the wind does not blow and the sun does not shine.

China's highest court has called for a crack down on the activities of paper mills, businesses that churn out fraudulent or poor-quality manuscripts and sell authorships. Nature: Some researchers are cautiously optimistic that the court's guidance will help curb the use of these services, while others think the impact will be minimal. "This is the first time the supreme court has issued guidance on paper mills and on scientific fraud," says Wang Fei, who studies research-integrity policy at Dalian University of Technology in China.

Paper mills sell suspect research and authorships to researchers who want journal articles to burnish their CVs. They are a significant contributor to overall research misconduct, particularly in China. Last month, the Supreme People's Court published a set of guiding opinions on technology innovation. Among the list of 25 articles, one called for lower courts to crack down on 'paper industry chains,' and for research fraud to be severely punished. Further reading:

Firefly Aerospace's Blue Ghost lander successfully touched down on the moon, making it the first private company to achieve a stable lunar landing without crashing. The craft is carrying various NASA-funded experiments, including a "vacuum to suck up moon dirt for analysis and a drill to measure temperature as deep as 10 feet (3 meters) below the surface," reports the Associated Press. There's also "a device for eliminating abrasive lunar dust -- a scourge for NASA's long-ago Apollo moonwalkers, who got it caked all over their spacesuits and equipment." From the report: A half hour after landing, Blue Ghost started to send back pictures from the surface, the first one a selfie somewhat obscured by the sun's glare. The second shot included the home planet, a blue dot glimmering in the blackness of space. Blue Ghost -- named after a rare U.S. species of fireflies -- had its size and shape going for it. The squat four-legged lander stands 6-foot-6 (2 meters) tall and 11 feet (3.5 meters) wide, providing extra stability, according to the company.

Launched in mid-January from Florida, the lander carried 10 experiments to the moon for NASA. The space agency paid $101 million for the delivery, plus $44 million for the science and tech on board. It's the third mission under NASA's commercial lunar delivery program, intended to ignite a lunar economy of competing private businesses while scouting around before astronauts show up later this decade.

Firefly's Ray Allensworth said the lander skipped over hazards including boulders to land safely. Allensworth said the team continued to analyze the data to figure out the lander's exact position, but all indications suggest it landed within the 328-foot (100-meter) target zone in Mare Crisium. The demos should get two weeks of run time, before lunar daytime ends and the lander shuts down.

NASA used specialized Schlieren photography to capture an image of Boom Supersonic's XB-1 demonstrator aircraft breaking the sound barrier on February 10, 2025 and producing shock waves as it exceeded Mach 1. The flight produced no audible sonic boom, marking progress toward the goal of quiet supersonic travel. CNN reports: "This image makes the invisible visible," said Blake Scholl, founder and CEO of Boom Supersonic, in a press release. In order to capture the Schlieren images, Boom chief test pilot Tristan "Geppetto" Brandenburg positioned XB-1 at an exact time in a precise location over the Mojave Desert.

As the aircraft flew in front of the sun, NASA's team documented the changing air speeds as speeds over Mach 1, the speed of sound (761.23 miles per hour or 1,225.1 kilometers per hour). The images were captured during ground telescopes with special filters that detect air distortions. You can view the photo here.

How confident are we about the safety of commercial space tourism? Long-time Slashdot reader theodp writes: It's one thing for Microsoft to boast that they dare to use Outlook instead of Gmail. But it took a whole other level of commitment for Jeff Bezos to join his brother Mark aboard Blue Origin's first passenger-carrying mission in July 2021.

So, while Bezos is unhesitant about sending himself and other celebrities and loved ones into space aboard Blue Origin, how confident are you about the current state of space travel safety?

If offered a free ride into space from Bezos's Blue Origin, or one of the other options like Virgin Galactic, Axiom Space, or Boeing's Starliner, would you accept or decline it?

Petawatt lasers have already allowed scientists to "manipulate materials in new ways, emulate the conditions inside planets, and even split atoms," reports Science magazine. "Now, accelerator physicists have matched that feat, producing petawatt pulses of electrons that could also have spectacular applications..." Described in a paper published Thursday in Physical Review Letters, the electron pulses last one-quadrillionth of a second but carry 100 kiloamps of current. "It's a supercool experiment," says Sergei Nagaitsev, an accelerator physicist at Brookhaven National Laboratory who was not involved in the work. Richard D'Arcy, a plasma accelerator physicist at the University of Oxford, adds, "It's not just an experimental demonstration of something interesting, it's a steppingstone on the way to megaamp beams." If achievable, those even more powerful beams might begin to perform extraordinary feats such as ripping particles out of empty space, he says...

[A]mped-up lasers would open the way to, for example, probing chemical processes as they happen, says Sergei Nagaitsev [an accelerator physicist at Brookhaven National Laboratory who was not involved in the experiment]. "These are the easy pickings." An ultraintense electron pulse could also be used to generate plasmas like those seen in astrophysics, such as the jets of matter and radiation that shoot out of certain stellar explosions at near-light-speed. Researchers need only fire the electron beam into the right target. "This is a fantastic relativistic drill," Ferrario says. "The interaction of this with matter could be very interesting."

Superintense electron bunches might someday even probe the nature of empty space. They produce a hugely intense electric field, so if one of them were to collide with an ultraintense laser pulse, which also contains a huge electric field, it would expose space to an incredibly strong electrical polarization, D'Arcy notes. If that field is strong enough, it should begin to rip particle-antiparticle pairs out of the vacuum, a phenomenon predicted by quantum physics but never observed. "You can access areas of particle physics that are inaccessible elsewhere," Darcy says.

Watch the "Blue Ghost" lunar lander attempt its moon landing.

The actual landing is scheduled to happen at 3:34 a.m. Eastern time, according to CNN, while "The first images from the mission should be delivered about a half hour after..." Success is not guaranteed... [B]roadly speaking, about half of all lunar landing attempts have ended in failure. Jason Kim, Firefly's CEO, told CNN in December that his company's experience building rockets has given him a high degree of confidence in Blue Ghost's propulsion systems. "We're using (reaction control system) thrusters that we've built, developed in-house, that are designed by the same people that design our rocket engines. That reduces risk," Kim said. "All that gives us high confidence when we have people that do rocket engines really, really well — some of the best in the world."
But the New York Times notes that Blue Ghost, built by Austin, Texas-based Firefly Aerospace, is just one of three robotic spacecraft "in space right now that are aiming to set down on the moon's surface." Blue Ghost has performed nearly perfectly. For the first 25 days, it circled Earth as the company turned on and checked the spacecraft's systems. It then fired its engine on a four-day journey toward the moon, entering orbit on February 13. The spacecraft's cameras have recorded close-up views of the moon's cratered surface...

On the same SpaceX Falcon 9 rocket that launched Blue Ghost to orbit was Resilience, a lunar lander built by Ispace of Japan. The two missions are separate, but Ispace, seeking a cheaper ride to space, had asked SpaceX for a rideshare, that is, hitching a ride as a secondary payload... Although Resilience launched at the same time as Blue Ghost, it is taking a longer, more fuel-efficient route to the moon and is expected to enter orbit around the moon in early May.
The third lunar lander heading to the moon is Athena (from Intuitive Machines), which launched Thursday on a SpaceX Falcon 9 rocket, "marking the first time humanity has had three lunar landers en route to the Moon at the same time," according to a statement from the company. Space.com notes that "To date, just one private spacecraft has ever landed successfully on the moon — Intuitive Machines' Odysseus, which did so in February 2024." Athena launched with several other spacecraft last night, including Odin, a scouting probe built by the asteroid-mining company Astroforge, and NASA's water-hunting Lunar Trailblazer. Lunar Trailblazer is also moon-bound, though it's headed for orbit rather than the surface...

Hidden layers of rock below the surface of Mars "strongly suggest" the presence of an ancient ocean, according to an international team of scientists including researchers at Penn State.

From the university's announcement: The new research offers the clearest evidence yet that the planet once contained a significant body of water and a more habitable environment for life, according to Benjamin Cardenas, assistant professor of geology at Penn State and co-author on the study. "We're finding places on Mars that used to look like ancient beaches and ancient river deltas," Cardenas said. "We found evidence for wind, waves, no shortage of sand — a proper, vacation-style beach."

The Zhurong rover landed on Mars in 2021 in an area known as Utopia Planitia and sent back data on the geology of its surroundings in search of signs of ancient water or ice. Unlike other rovers, it came equipped with rover-penetrating radar, which allowed it to explore the planet's subsurface, using both low and high-frequency radar to penetrate the Martian soil and identify buried rock formations. By studying the underground sedimentary deposits, scientists are able to piece together a more complete picture of the red planet's history, Cardenas explained. When the team reviewed radar data, it revealed a similar layered structure to beaches on Earth: formations called "foreshore deposits" that slope downwards towards oceans and form when sediments are carried by tides and waves into a large body of water.

"This stood out to us immediately because it suggests there were waves, which means there was a dynamic interface of air and water," Cardenas said. "When we look back at where the earliest life on Earth developed, it was in the interaction between oceans and land, so this is painting a picture of ancient habitable environments, capable of harboring conditions friendly toward microbial life." When the team compared the Martian data with radar images of coastal deposits on Earth, they found striking similarities, Cardenas said. The dip angles observed on Mars fell right within the range of those seen in coastal sedimentary deposits on Earth...

The study also provided new information on the evolution of the Martian environment, suggesting that a life-friendly warm and wet period spanned potentially tens of millions of years.
Mars "was evolving," Cardenas says in the announcement. "Rivers were flowing, sediment was moving, and land was being built and eroded.

"This type of sedimentary geology can tell us what the landscape looked like, how they evolved, and, importantly, help us identify where we would want to look for past life."

CNN notes that the research was published Monday in the journal Proceedings of the National Academy of Sciences.

San Francisco-based biotech startup Loyal says a drug it developed to increase dogs' lifespan "has passed a significant milestone on the way to regulatory approval," reports the Washington Post: The Food and Drug Administration certified the daily pill as having a "reasonable expectation of effectiveness" at extending senior dogs' lifespans. The regulator's Center for Veterinary Medicine still has to certify that the drug is safe and that Loyal can manufacture it at scale before vets can prescribe the pill to dogs 10 years or older that weigh 14 pounds or more. Loyal's CEO, Celine Halioua, estimates that the process should be complete by the end of 2025 and called the FDA's initial recognition "a key step" to extending dogs' lives...

In the past decade, a subculture of tech entrepreneurship has focused on helping people stave off death, hawking custom-made dietary supplements and $2,500 full-body MRIs and investing in the development of antiaging drugs, among many other efforts. According to data firm Pitchbook, about $900 million in venture capital has been poured into antiaging and longevity start-ups in the past 12 months. Loyal has raised more than $150 million in venture funding since its 2019 founding to develop lifespan-extending drugs initially focused on canines.

Launching veterinary drugs is in some ways easier than winning approval for human treatments. Because dogs and humans have evolved alongside one another, Halioua hopes to eventually apply her findings about pets to help prolong their owners' lives. "If we can successfully delay the onset and severity of age-related diseases in dogs, it's extremely compelling evidence that it will also do that in humans," Halioua said. The biological processes of aging unfold faster in dogs because they live such short lives, she said, helping researchers and entrepreneurs probe how they work.
"Loyal's pill is a result of research into how to mimic the life-extending benefit of caloric restriction without the appetite suppression," according to the article, "and without the need for an owner to restrict their dog's food.

"The drug aims to improve a dog's metabolic fitness, or the body's ability to convert nutrients into energy and regulate hormones, which declines in humans and canines with age..."

Chinese scientists are developing a lightweight Mars drone capable of both rolling on the ground and flying using contra-rotating coaxial rotors. Space.com reports: The air-ground dual-purpose unmanned aerial vehicle (UAV) weighs only 10.6 ounces (300 grams), equivalent to the weight of an apple. The development team is at the School of Astronautics (SoA) of the Harbin Institute of Technology. Seen as showing promising potential in future Mars science work, the UAV can take off at any time, traverse obstacles, and boasts superb endurance, reports state-owned China Central Television (CCTV).

"On the ground, it mainly rolls by shifting its center of gravity," said Zhu Yimin, a Ph.D candidate at SoA. "In the air, it relies on a pair of contra-rotating coaxial rotors, controlled by a steering engine to adjust the forward direction, to control torque and force, ultimately achieving stable flight," Zhu told CCTV. The UAV work entails multiple models of air-ground dual-mode robots with different configurations, CCTV reports. These robots move by rolling close to the ground, which reduces energy consumption, and can achieve a flight endurance time of more than six times that of traditional drones of the same size.

According to Zhang Lixian, a professor within the SoA, the hope is that the aerial vehicle can show off its long endurance and observational abilities on Mars. "Our second goal is for such machines to be suitable for construction in many underground spaces and for exploring unknown underground spaces. We also need robotic means for inspection and environmental detection. We have now materialized all these functions," said Zhang. A video of the drone can be found here.

Blue Origin on Thursday announced the crew for its next mission. "The crew most notably includes popstar Katy Perry and broadcast journalist Gayle King. They will be joined by two scientists -- Aisha Bowe and Amanda Nguyen -- as well as Jeff Bezos' fiancee, TV personality Lauren Sanchez and film producer Kerianne Flynn," reports TechCrunch. From the report: Blue Origin says this marks the first all-female space crew since Soviet astronaut Valentina Tereshkova's 1963 solo mission, which made her the first woman ever to go to space. For the company's New Shepard rocket, this is its 31st trip to space, and its 11th with a crew. This journey is expected to last around 10 to 12 minutes; and if you're willing to drop a $150,000 deposit, you too can reserve a future spot on a short space jaunt.

Google has received FDA clearance for the Pixel Watch 3's Loss of Pulse Detection feature, which will start rolling out to U.S. devices around the end of March. The Verge reports: The Loss of Pulse Detection feature is exactly what it sounds like: if the Pixel Watch 3 senses that you've lost your pulse through an event like a heart attack or an overdose, it'll send you a prompt. If you don't respond, it'll automatically call emergency services on your behalf. Back in August, Sandeep Waraich, Google's senior director of product manager for Pixel wearables, told The Verge that the Pixel Watch 3 is capable of differentiating between a genuine loss-of-pulse event and a person simply taking the watch off.

New research suggests that anthocyanins, the antioxidants responsible for the vibrant colors of fruits and flowers, may help counteract reproductive harm caused by microplastics. The Guardian reports: The new review of scientific literature on anthocyanins found that the compounds are probably protective against a range of plastic-induced impacts on hormones, reductions in testosterone and estrogen, decreased sperm counts, lower sperm quality, erectile dysfunction and ovarian damage. [...] Researchers said that mice exposed to microplastics, then treated with anthocyanins, showed increased sperm quality, including increased sperm count and motility, and the antioxidants overall reduced testicular damage. The new paper also pointed to research that found some microplastics reduce testosterone levels because they harm Leydig cells, which are responsible for the hormone's production. Anthocyanins seem to helped restore testosterone production and protect Leydig cells.

In women, impacts on fertility and sexual development could be mitigated by anthocyanins that seem to protect hormone receptors from plastic chemicals such as bisphenol, phthalates and cadmium. The chemicals can mimic hormones, or cause hormonal responses. Microplastics in ovarian tissue cause inflammation that seems to lower levels of estrogen and other hormones. Research found that treating rats exposed to microplastics protected the ovarian tissue and normalized levels of estrogen and other hormones. "Its antioxidant properties help preserve ovarian function and potentially maintain fertility, highlighting its therapeutic potential in managing ovarian damage," the authors wrote.

Asteroid 2024 YR4, once considered a significant impact risk, has been reassigned to Torino Scale Level Zero and therefore poses no hazard to Earth. "The NASA JPL Center for Near-Earth Object Studies (CNEOS) now lists the 2024 YR4 impact probability as 0.00005 (0.005%) or 1-in-20,000 for its passage by Earth in 2032," Richard Binzel, Professor of Planetary Science at the Massachusetts Institute of Technology (MIT) and creator of the Torino scale exclusively told Space.com. "That's impact probability zero folks!" From the report: Discovered in Dec. 2024, 2024 YR4 quickly climbed to the top of NASA's Sentry Risk table, at one point having a 1 in 32 chance of hitting Earth. This elevated it to Level 3 on the Torino scale, a system used since 1999 to categorize potential Earth impact events. Level 3, which falls within the yellow band of the Torino Scale, is described as: "A close encounter, meriting attention by astronomers. Current calculations give a 1% or greater chance of collision capable of localized destruction."

This conforms to the second part of the Torino scale level 3 description, which states: "Most likely, new telescopic observations will lead to re-assignment to Level 0. Attention by public and by public officials is merited if the encounter is less than a decade away." "Asteroid 2024 YR4 has now been reassigned to Torino Scale Level Zero, the level for 'No Hazard' as additional tracking of its orbital path has reduced its possibility of intersecting the Earth to below the 1-in-1000 threshold," Binzel continued. "1-in-1000 is the threshold established for downgrading to Level 0 for any object smaller than 100 meters; YR4 has an estimated size of 164 feet (50 meters)."

[...] While 2024 YR4 poses no threat, it will still have a major scientific impact when it passes Earth in 2028 and again in 2032. On Dec. 17, the asteroid will come to within 5 million miles of Earth. Then, on Dec.22, 2032, 2024 YR4 will pass within just 167,000 miles of our planet. For context, the moon is 238,855 miles away.

"Elizabeth Holmes' fraud conviction has been upheld by a federal appellate panel," writes Slashdot reader ClickOnThis. MSNBC reports: A three-judge panel of the 9th U.S. Circuit Court of Appeals on Monday affirmed the convictions, sentences and nine-figure restitution ordered against both Holmes and Theranos president, Ramesh "Sunny" Balwani. [...] Theranos was supposedly going to revolutionize medical laboratory testing with the ability to run fast, accurate and affordable tests with just a drop of blood from a finger prick. "But the vision sold by Holmes and Balwani was nothing more than a mirage," 9th Circuit Judge Jacqueline H. Nguyen wrote (PDF) for the panel, adding that the "grandiose achievements touted by Holmes and Balwani were half-truths and outright lies."

Holmes was convicted of crimes related to fraud against investors while the jury acquitted her or hung on other counts. Balwani was convicted on all counts at his trial. The federal panel rejected a slew of arguments from both defendants, including that their trials featured improper testimony from Theranos employees. While the ruling is a major setback for the defendants, they can further appeal to a fuller panel of 9th Circuit judges and the Supreme Court, which generally has broad discretion over whether to accept cases for review.

Long-time Slashdot reader schwit1 shared this observation from space/science news blogger Robert Zimmerman: Having now reached lunar orbit in preparation for its landing on March 2, 2025, an engineering test instrument on Firefly's Blue Ghost lunar lander has now proven that even from that distance spacecraft can use the multiple GPS-type satellites in Earth orbit to track their position.

[From NASA.gov]: The Lunar GNSS Receiver Experiment (LuGRE) acquired and tracked Global Navigation Satellite System (GNSS) signals for the first time in lunar orbit – a new record! This achievement, peaking at 246,000 miles, suggests that Earth-based Global Navigation Satellite System constellations can be used for navigation in transit to, around, and potentially on the Moon. It also demonstrates the power of using multiple GNSS constellations together, such as GPS and Galileo, to perform navigation.

After lunar landing, LuGRE will operate for 14 days and attempt to break another record – first reception of GNSS signals on the lunar surface.

This test is a very big deal. It tells us that operations on the Moon, at least those on the near side, will likely not require a GPS-type infrastructure in lunar orbit, thus allowing a lot of difficult missions to proceed sooner while saving a lot of money and time.

An anonymous reader shared this report from ABC News: Elon Musk called this week for the deorbiting of the International Space Station (ISS) "as soon as possible." "It is time to begin preparations for deorbiting the [ISS]," Musk wrote in a post on X on Thursday. "It has served its purpose. There is very little incremental utility. Let's go to Mars." In a follow-up post, Musk said he was planning to recommend to President Donald Trump that the station be brought down "as soon as possible" and that the 2030 timeline for deorbiting be moved up to two years from now.
Jordan Bimm, space historian and professor of science communication at the University of Chicago, told ABC News what he thinks was one of the most important findings to come out of ISS research: "that microgravity affects the body in lots of deleterious ways." "That leads to your bone loss, muscle loss, changes in the fluid inside our bodies that are normally being pulled down by Earth's gravity, changes to the eye and vision loss and things like that. We have gotten good data on how that progresses over time, and importantly, we have developed countermeasures for these things as well, including resistance training or running on a treadmill, things like that..."
