NASA’s Crew-13 could set a new U.S. record by reaching the International Space Station in just 7 hours and 50 minutes. NASA will broadcast the major events surrounding its SpaceX Crew-13 mission to the International Space Station, including preparations before liftoff, the launch itself, and the spacecraft’s arrival and docking. Coverage will be available across [...]

Researchers have visualized two key stages of RNA processing in parasites that cause diseases such as sleeping sickness, Chagas’ disease, and leishmaniasis. For nearly 40 years, scientists have known that trypanosomatid parasites depend on an unusual system for processing RNA. Now researchers have captured that machinery at near-atomic resolution, showing how its components assemble and [...]

A mouse study suggests that neighboring visual areas may build agreement by sustaining shared activity patterns while mismatches fade. A shape in the dark might briefly resemble a face, or an orange might momentarily look like an apple. To make sense of what we see, the brain must coordinate information from regions with different specialties. [...]

Shielded from most of Earth’s magnetic field, fruit flies with faulty mitochondria lived about 20% longer, but their physical performance declined. Life on Earth has always operated within a constant, invisible background. The planet’s magnetic field continuously passes through every living cell, yet biologists still know very little about whether organisms actually need this environmental [...]

Binghamton researchers are examining brain patterns across different ages to identify where memories become mixed up. Memory errors do not always mean the brain failed to reactivate an earlier memory. In older adults, researchers found a more unexpected pattern: stronger reactivation of a memory pattern in the hippocampus was associated with a greater likelihood of [...]

Children’s nutritional needs deserve attention from the start of GLP-1 treatment, as a study found limited counseling and nutritional deficiencies, most commonly vitamin D deficiency, during crucial years of growth. Nearly one in six children prescribed GLP-1 medications for weight loss, prediabetes, or type 2 diabetes was diagnosed with a nutritional deficiency within a year [...]

A shorter daily eating window was linked to improved eating habits, with no clear advantage in measured appetite hormones or inflammation markers. Time-restricted eating asks people to fit their meals into the same eight- to 10-hour window each day. Because people may also eat less on that schedule, researchers at Johns Hopkins Medicine set out [...]

NASA and SpaceX are nearing launch of Crew-13, a four-person mission that could reach the International Space Station in less than nine hours. NASA and SpaceX are targeting 11:10 a.m. EDT on Thursday, October 1, as the earliest opportunity to launch the Crew-13 mission to the International Space Station. Before liftoff, teams will complete final [...]

Curiosity marked 5,000 days on Mars with a vivid new postcard showing its tracks across Gale Crater. NASA’s Curiosity Mars rover has captured a striking new view of the Red Planet while stopped at a sandy ridge nicknamed “Chocolatal.” Using its black-and-white navigation cameras, the rover photographed the surrounding landscape at two different times of [...]

Even planets billions of years older than Earth may host only microbes if photosynthesis supplies too little energy. Science fiction often imagines Earth’s galactic neighborhood teeming with hyper-advanced extraterrestrial civilizations, but the actual cosmos near us may be far quieter. A study published in the International Journal of Astrobiology, led by Chris Doughty, a professor [...]

‘Plasticorals,’ pieces of coral rubble fused with plastic, are lasting signs of human activity and may pose a threat to marine ecosystems. While widely manufactured materials like cement and steel degrade over millennia, plastic remains intact long enough that future geologists will likely identify the period from the 1950s onward as a distinct synthetic layer [...]

A nearly 2,000-year-old volcanic disaster is helping scientists refine the clocks used to reconstruct Earth’s history. Nearly 2,000 years after Mount Vesuvius buried Pompeii, the eruption is serving as a calibration point for one of geology’s most widely used dating methods. The key is that the disaster occurred within recorded history. Pliny the Younger described [...]

As glaciers retreat, steep Arctic fjords may face rising landslide-tsunami risks that could be reduced through better monitoring and faster warnings. On the evening of August 9, 2025, passengers aboard the Hanse Explorer had just finished photographing and filming South Sawyer Glacier before the vessel began its trip back through the fjord. About 12 hours [...]

By targeting the retina’s protective barrier, oral Danegaptide could help treat diabetic eye damage earlier, though its lasting benefits remain to be tested. For millions of people with diabetes, treating vision-threatening eye damage means waiting until vision loss has already begun, at which point doctors must deliver regular anti-VEGF injections directly into the eye. These [...]

Researchers found that potential breast cancer-related chemical exposures may come from far more sources than previously recognized. A new study from the Silent Spring Institute has identified hundreds of chemicals in pesticide formulations that could potentially increase breast cancer risk. The list includes both active pesticide ingredients and many so-called “inert” ingredients, which generally receive [...]

In a small study, a drug increased calorie burning without clearly switching on brown fat, the heat-producing tissue scientists hope to harness to help people lose weight. Brown fat burns energy to keep us warm, and researchers hope a drug could put that ability to work against obesity. In a small human study, the drug [...]

The fluid surrounding the brain may hold another clue to Alzheimer’s, with elevated levels of an enzyme called meprin-β raising the possibility of a new disease indicator. One of the defining features of Alzheimer’s disease is the buildup of beta-amyloid, a protein fragment produced when enzymes cut a larger protein called amyloid precursor protein into [...]

Consistently high and irregular levels of the stress hormone cortisol are linked to faster cognitive decline in older adults. Releasing the hormone cortisol is the human body’s natural way of responding to stress. Because cortisol can cross the blood-brain barrier and bind to receptors in regions responsible for cognition, researchers have long suspected that chronic [...]

Some of coffee’s most unusual effects have little to do with caffeine. Its other bioactive compounds can interact with the gut, medications, and nutrients in ways researchers are still trying to understand. Coffee is best known, and perhaps most valued, for its caffeine and its ability to make us feel more awake and alert. But [...]

A distant quasar’s distorted images could hold clues to what dark matter is made of. Simulations of dark matter behaving like waves now offer a closer match to where those images appear. When the gravity of a massive object bends light from a more distant source, it creates distorted, multiple images of galaxies in a [...]

New orbital evidence suggests the young Moon may once have generated its own magnetic field from deep within its interior. A buried volcanic structure on the Moon’s far side may provide some of the strongest evidence yet that the young Moon once generated its own magnetic field. Researchers combined gravity data from NASA’s GRAIL mission [...]

Two new studies suggest that Saturn’s moon Enceladus may be an even more compelling target in the search for extraterrestrial life. If scientists want to search an alien ocean for life, Enceladus offers a rare advantage: the ocean sends samples into space. Saturn’s icy moon hides a global ocean beneath its frozen surface, but researchers [...]

Researchers captured how a molecule and its surrounding water reorganize together during a rapid energy-transfer reaction that plays a key role in nature. A chemical process central to photosynthesis, metabolism, and other forms of energy conversion has now been captured in unusual detail, revealing how a molecule and the water around it change together as [...]

Researchers used nanoscale manufacturing techniques from the semiconductor industry to design a copper current collector that helps lithium build up evenly during battery charging. Electric vehicles could travel farther on a single charge if their batteries could store more energy without getting bigger or heavier. A promising alternative, known as an anode-free battery, eliminates materials [...]

Lutetium clocks have achieved record accuracy and comparison precision, making them promising candidates for future time standards and measurements of gravity. An atomic clock built from the element lutetium at the Centre for Quantum Technologies (CQT) at the National University of Singapore (NUS) has set a new benchmark for timekeeping accuracy. Results published in Nature [...]

Some brains appear to age faster than their owners, and clues to that difference may be hiding in the gut. A UCLA Health study links patterns of brain activity in generally healthy adults to gut bacteria and the chemicals associated with them. The findings raise the possibility that biological signs of brain aging can be [...]

A probable defensive structure at Oued Beht suggests communities in northwestern Africa coordinated large building projects about 4,000 to 3,500 years ago. At Oued Beht, an archaeological site in the hills of northwestern Morocco, a large, wall-like structure suggests that people were protecting their communities or asserting control over the surrounding landscape about 4,000 to [...]

By simulating a billion years of Earth’s history, researchers have identified a possible window for life’s earliest chemistry around 4.33 billion years ago. During its first few hundred million years, Earth was a hostile target. Asteroids, comets, and leftover planetesimals, smaller bodies remaining from planet formation, relentlessly battered the planet, generating intense heat that could [...]

A Yellowstone supereruption could set off a global survival crisis, with food shortages and damaged health systems extending the danger long after the initial blasts. Around 631,000 years ago—a geological blink of an eye—catastrophe unfolded in what is now northwestern Wyoming, US. During what is thought to have been a series of immense volcanic eruptions, [...]

Differences in brain activity are linked to difficulties using and adapting math problem-solving strategies in children with developmental dyscalculia. Choosing how to tackle a math problem can be a challenge of its own for children with developmental dyscalculia, a condition marked by persistent difficulty with math problem-solving. A Stanford University study connects these struggles with [...]

A pilot study suggests that oil from underused Hinoki roots could be used in scented products for relaxation. Falling asleep can be compared to easing down a dimmer switch, with brain activity gradually shifting as sleep deepens. Researchers studying Hinoki, or Japanese cypress, are exploring whether its scent could help smooth that transition for women [...]

Obesity may leave behind a cellular memory that pushes the body to regain lost weight. Researchers at the Harrington Discovery Institute at University Hospitals and Case Western Reserve University have uncovered a mechanism that could help explain two stubborn features of obesity: why lost weight so often returns and why heightened susceptibility can pass from [...]

After making history around the Moon, Victor Glover and Reid Wiseman are beginning a new chapter while helping NASA prepare for what comes next. NASA astronauts Victor Glover and Reid Wiseman are moving into emeritus roles at Johnson Space Center in Houston this September, months after completing the historic Artemis II mission. The emeritus program [...]

NASA’s Roman Space Telescope has powered up its 300-megapixel cosmic camera, bringing its first sweeping views of the universe closer than ever. NASA’s Nancy Grace Roman Space Telescope has reached an important milestone after successfully switching on its Wide Field Instrument, a 300-megapixel infrared camera designed to survey enormous areas of the universe quickly while [...]

Researchers at Queen Mary University of London helped identify a planet’s backward orbit, which could offer clues to how planetary systems form and evolve. When a star and its planets form from the same spinning disk of gas and dust, the planets are expected to orbit in the direction the star rotates. Astronomers have now [...]

Among several diets tested in a clinical trial, a ketogenic diet produced the greatest improvements in liver and metabolic health. Losing the same amount of weight does not necessarily produce the same metabolic benefits. In a randomized clinical trial, three very different diets helped adults with obesity lose about 10% of their starting weight, but [...]

Healthy habits may reduce some of the health burden associated with social isolation, but loneliness appears to be more resistant to lifestyle changes. Living longer is only part of the health equation. Another question is how many of those years are spent free from major physical and mental illnesses. New research suggests that the quality [...]

Atherosclerosis may begin shockingly early, with artery scans revealing hidden plaque in about one in 13 adults before age 30. An international study of 16,808 adults found that silent atherosclerosis is far more common than symptoms or routine risk assessments suggest. Advanced scans detected plaque in 57.1% of participants with no known cardiovascular disease, revealing [...]

A new study suggests that black-browed albatrosses may not evolve fast enough to keep pace with climate change. Cutting greenhouse gas emissions could give them a better chance of survival. Black-browed albatrosses, long-lived seabirds of the Southern Ocean and surrounding seas, may need more time to adapt to climate change than a warming world allows. [...]

The discoveries could help manage stick insect outbreaks and reduce their impact on forestry and agriculture. Australia’s coastal landscapes are home to large stick insects belonging to the genus Anchiale, a group of closely related species. For decades, scientists and nature enthusiasts have documented them, uploading more than a thousand observations to databases like iNaturalist [...]

The discovery could lead to more targeted treatments that reduce inflammation linked to high blood pressure. For nearly half of U.S. adults who have high blood pressure, controlling the condition can be a persistent challenge. Researchers at the University of Missouri are investigating whether a protein called TG2, found in blood vessels and certain immune [...]

Routine chest CT scans may contain clues about more than bone health. A scan taken to examine the chest may also reveal clues about how the brain is aging. Researchers at Johns Hopkins University found that people with lower bone mineral density in the spine tended to experience faster cognitive decline and more rapid changes [...]

New research suggests creatine may help adults ages 45 to 65 gain lean tissue and strength, even without a structured exercise program. Creatine, a naturally occurring compound that helps replenish cellular energy, is widely used to build muscle and improve athletic performance. Its effects may also be useful in middle age, when maintaining muscle becomes [...]

Scientists were surprised to discover a fossilized tooth from a capybara that lived almost 9 million years ago in what is now northern Chile’s Atacama Desert. Chile’s Atacama Desert is an unlikely place to find traces of capybaras, the world’s largest living rodents, whose lives revolve around water and wetland plants. Yet a fossilized tooth [...]

A newly identified amoeba from a volcanic region of California is challenging long-held assumptions about how much heat complex cells can withstand. Heat can quickly become destructive to complex cells. As temperatures rise, proteins can lose their shape, DNA can sustain damage, and essential cellular processes can begin to fail. This has made extreme heat [...]

Unusual fossils from an ancient North Sea delta may reveal where plesiosaurs fed. Fossilized vomit is not the kind of evidence paleontologists usually dream about finding. But it may have revealed an unexpected part of plesiosaur behavior. More than 20 fossilized masses recovered from rocks beneath the North Sea contain shells and other hard remains [...]

An analysis of more than 1,000 gene activity profiles from mouse brains reveals shared molecular patterns that vary by sex and respond differently to experimental drugs. Autism spectrum disorder (ASD), a condition involving differences in brain development, has been linked to more than 1,200 risk genes. Studying mutations individually has revealed many effects on the [...]

Ice baths, massage, compression gear, and supplements promise faster recovery, but the science shows that feeling less sore does not always mean your muscles have actually recovered. An ice bath may help sore muscles feel better after a hard workout, but using one too often could come with a trade-off. Less soreness now may also [...]

The search for effective anti-aging treatments has produced clear front-runners: healthy lifestyle changes and certain prescription drugs. Raghav Sehgal originally came to Yale hoping to apply computer science to cancer. With an engineering background and experience building a computational biology startup, he was well positioned to investigate the disease through data. His research direction changed [...]

Physicists have observed “Bethe strings” in an ultracold gas nearly a century after Hans Bethe predicted them, providing a controlled setting for further study. In 1931, physicist Hans Bethe predicted that particles in certain quantum systems could bind together into groups called Bethe strings. These groups could exist only in one dimension, where particles move [...]
