Sunita Williams and Butch Wilmore’s Return to Earth Confirmed: Know How and When NASA Astronauts Will Return After 9 Month Extended Stay in Space; Here’s Details

NASA has confirmed that Sunita Williams and Barry Wilmore will return to Earth in late March 2025 after spending over nine months aboard the ISS. Their return is scheduled to take place once the Crew-10 mission successfully arrives at the space station. Crew-10, carrying four new astronauts, will launch on March 12, 2025, at 7:48 PM EDT and undergo a week-long handover process before Williams and Wilmore begin their journey back. The decision to return them aboard a SpaceX Crew Dragon capsule was made due to ongoing technical issues with Boeing’s Starliner. NASA has assured that all necessary preparations are in place to facilitate a safe return.

Williams and Wilmore’s return capsule, the SpaceX Crew Dragon, will follow a carefully planned re-entry trajectory before making a splashdown in designated waters. NASA has shortlisted landing sites in the Atlantic Ocean and the Gulf of Mexico, with the final decision depending on weather and oceanic conditions at the time of descent. SpaceX recovery teams will be stationed near the landing zone, ready to retrieve the capsule and transport the astronauts back to shore. After landing, Williams and Wilmore will undergo a thorough medical assessment before heading to NASA’s facilities for debriefing.

Sunita Williams’ return to Earth marks the end of an unexpectedly extended mission that was originally planned for just ten days but stretched to over nine months. The delay was primarily due to technical issues with Boeing’s Starliner, which faced multiple failures, including propulsion system malfunctions and propellant leaks. NASA, prioritising astronaut safety, decided to postpone their return until a reliable alternative was arranged.

Move Over Smart Rings. MIT’s New Fabric Computer Is Stitched Into Your Clothes

That’s what prompted MIT engineers to create a fabric computer that can be stitched into regular clothes. The device features sensors, processors, memory, batteries, and both optical and Bluetooth communications, allowing networks of these fibers to provide sophisticated whole-body monitoring.

“Our bodies broadcast gigabytes of data through the skin every second in the form of heat, sound, biochemicals, electrical potentials, and light, all of which carry information about our activities, emotions, and health,” MIT professor Yoel Fink, who led the research, said in a press release.

“Wouldn’t it be great if we could teach clothes to capture, analyze, store, and communicate this important information in the form of valuable health and activity insights?”

Powered by renewable energy, microbes turn CO2 into protein and vitamins

It turns out acetate-fed yeast produces about the same amount of vitamin B9 as those that eat sugar. Just 6 grams, or 0.4 tablespoon, of the harvested dried yeast meets the daily vitamin B9 requirement. The vitamin levels were measured by a team led by co-author Michael Rychlik at the Technical University of Munich, Germany.

For protein, the researchers found that the levels in their yeast exceed those of beef, pork, fish, and lentils. Eighty-five grams, or 6 tablespoons, of yeast provides 61% of daily protein needs, while beef, pork, fish, and lentils meet 34%, 25%, 38%, and 38% of the need, respectively. However, the yeast should be treated to rid compounds that can increase the risk of gout if consumed excessively. Even so, treated yeast still meets 41% of the daily protein requirement, comparable to traditional protein sources.

This technology aims to address several global challenges: environmental conservation, food security, and public health. Running on clean energy and CO2, the system reduces carbon emissions in food production. It uncouples land use from farming, freeing up space for conservation. Angenent also stresses that it will not outcompete farmers. Instead, the technology will help concentrate farmers to produce vegetables and crops sustainably. The team’s yeast may also help developing nations overcome food scarcity and nutritional deficiencies by delivering protein and vitamin B9.

It seems like something out of a movie — they successfully achieve the first quantum teleportation in history

The future is coming and much faster than we think. Let’s do an exercise of imagination, imagine, for a moment, being able to send information from one point to another without the need for cables, Wi-Fi or traditional signals, more or less like something telepathic, right? Well, that is precisely what scientists have recently achieved at the University of Oxford: teleporting data between two quantum computers. Although it may seem like science fiction or just news, the world.

Although, let’s lower the hype a little, the transmission distance of this experiment was less than two meters, but that doesn’t matter, what matters is having achieved this milestone of sharing information without the need for connections.

Scientists Find Never-Before-Seen Fat Cell Types That May Hold the Key to Fighting Obesity

A groundbreaking international study, led by scientists from Ben-Gurion University of the Negev, has mapped the diverse populations of fat cells across different human fat tissues. Using advanced technology, researchers identified distinct subpopulations of fat cells with more complex functions than previously understood. They also discovered variations in how fat tissues communicate at the cellular level.

Published in Nature Genetics, these findings lay the foundation for future research aimed at advancing personalized medicine for obesity.

The research team, led by Prof. Esti Yeger-Lotem and Prof. Assaf Rudich from the Department of Clinical Biochemistry and Pharmacology at the Faculty of Health Sciences at Ben-Gurion University of the Negev, in collaboration with Prof. Naomi Habib from the Hebrew University of Jerusalem, Profs. Matthias Bluher, Antje Korner and Martin Gericke from the University of Leipzig, Germany, and Prof. Rinki Murphy from the University of Auckland, New Zealand, studied the diversity of fat cells in subcutaneous and intra-abdominal (visceral) fat tissues in humans.

Common Fungal Compound May Be the Key to Fighting Deadly Flu Infections

Preclinical trial reveals how beta-glucan, a compound found in all fungi, can ‘reprogram’ immune cells to combat lung inflammation.

A recent study suggests that a common fungal component may help protect against flu-related lung damage.

Led by Professor Maziar Divangahi from McGill’s Faculty of Medicine and Health Sciences and the Research Institute of the McGill University Health Centre, the research team found that beta-glucan, when given to mice before influenza exposure, reduced lung damage, improved lung function, and lowered the risk of severe illness and death.

Understanding raw milk’s disease risk — and pasteurization’s importance

Raw milk has made headlines recently for widespread samples containing the virus that causes H5N1, or bird flu, with the U.S. Department of Agriculture launching a program in December to track the virus through milk testing. But bird flu is far from the only disease-causing pathogen lurking in raw milk: Unpasteurized milk can contain bacteria such as E. coli and Listeria, for instance.

New Stanford Medicine research has found that another virus affecting both animals and people — Rift Valley fever virus — can remain active in raw milk samples for roughly as long as someone might want to drink it. Rift Valley fever is an acute viral illness spread to people through mosquitoes or the bodily fluids of infected animals. These findings mirror recent Stanford research showing that flu virus can be infectious in refrigerated raw milk for up to five days.

While Rift Valley fever virus mostly impacts sub-Saharan Africa, these findings have important implications for understanding human disease risk from drinking raw milk, said Brian Dawes, MD, PhD. He is an infectious disease fellow and postdoctoral researcher in Stanford Medicine’s LaBeaud Lab and led the research. Desiree LaBeaud, MD, associate dean of global health, was the senior author. Alina De La Mota-Peynado of the USDA was co-lead author.

The Biggest AI for Biology Yet Writes Genomes From Scratch

A new algorithm, Evo 2, trained on roughly 128,000 genomes—9.3 trillion DNA letter pairs—spanning all of life’s domains, is now the largest generative AI model for biology to date. Built by scientists at the Arc Institute, Stanford University, and Nvidia, Evo 2 can write whole chromosomes and small genomes from scratch.

It also learned how DNA mutations affect proteins, RNA, and overall health, shining light on “non-coding” regions, in particular. These mysterious sections of DNA don’t make proteins but often control gene activity and are linked to diseases.

The team has released Evo 2’s software code and model parameters to the scientific community for further exploration. Researchers can also access the tool through a user-friendly web interface. With Evo 2 as a foundation, scientists may develop more specific AI models. These could predict how mutations affect a protein’s function, how genes operate differently across cell types, or even help researchers design new genomes for synthetic biology.
