A new study reveals that gut bacteria may play a key role in triggering ALS and frontotemporal dementia. Harmful sugars produced by these microbes can spark immune responses that damage the brain. This breakthrough explains why some genetically at-risk people develop the
A week after astronaut Jeremy Hansen blasted off on the historic Artemis II mission to the moon, his wife Catherine recalled the anxiety and thrill of witnessing the journey from afar.
Before NASA’s moon mission launched, experts sounded the alarm over the Orion capsule’s heat shield and reentry. Now splashdown is just one day away
Lunar love knows no bounds. Now hurtling home from the moon, the Artemis II astronauts took a poignant page from Apollo 8 earlier this week, proposing deeply personal names for a pair of lunar craters.
A shallow 4.9-magitude earthquake struck eastern Indonesia overnight, damaging dozens of homes and injuring multiple people, an official said Thursday.
Halting and reversing the global decline in biodiversity is now urgent to avoid destabilizing Earth's vital systems that support human well-being. That's the stark message of a new paper published today in Frontiers in Science. The authors warn that without protecting remaining
Researchers at Bar-Ilan University have discovered that changing just one letter in DNA can completely alter sex development in mice. In the new study, published in Nature Communications, a single-letter insertion in a non-coding regulatory region caused XX mice, which would
March's persistent unseasonable heat was so intense that the continental United States registered its most abnormally hot month in 132 years of records, according to federal weather data. And the next year or so looks to turn the dial up on global warmth even more, as some
Not all parts of our genetic code are equal, even when they appear to say the same thing. Scientists have discovered that cells can detect less efficient genetic instructions and selectively silence them. A protein called DHX29 plays a key role in this process by identifying
Canadian astronaut Jeremy Hansen told Prime Minister Mark Carney on Wednesday that "teamwork is willingness" during an Earth-to-space call celebrating the achievements of the historic lunar journey.
After a successful trip around the moon, everything has been going smoothly on the Orion spacecraft's journey back to Earth—except for the $23 million toilet, which has gotten clogged.
There is an explosion of color beneath the surface in Raja Ampat, a remote archipelago in eastern Indonesia where sharks, mantas and sea turtles glide alongside vast schools of fish through sea fan coral formations, some of which are only found in its waters.
Listening to one-minute-long audio recordings of forests had positive effects on people's short-term well-being, especially when the recordings were from local temperate forests. Study participants residing in Germany perceived soundscapes as more awe-inspiring and restorative
Weight loss drugs and bariatric surgery may work differently, but they lead to surprisingly similar results inside the body. Both significantly reduce fat while also causing a modest loss of muscle, reshaping overall body composition. Since muscle helps protect against early
Chronic inflammation often works quietly in the background but can fuel serious diseases like diabetes, heart disease, and cancer. New research reveals that everyday plant compounds—like menthol from mint, cineole from eucalyptus, and capsaicin from chili peppers—can team up
Scientists have uncovered compelling evidence that humans reached New Guinea and Australia around 60,000 years ago—earlier than some recent theories suggested. By tracing maternal DNA lineages, the team discovered that these early travelers likely used at least two different
The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology and Astroparticle Physics, which aims to redefine how we search for dark matter, showing that it may not be necessary to find the same "clues" everywhere
Scientists have developed a clever new way to trap “forever chemicals” in water using nano-sized cages that lock onto PFAS molecules. Unlike current methods, this approach can capture short-chain PFAS—the hardest type to remove. Tests show it can eliminate up to 98% of these
Scientists have uncovered a surprising new player in Alzheimer’s disease: a protein called CSE that helps produce tiny amounts of hydrogen sulfide gas in the brain. In experiments with genetically engineered mice, removing this protein led to memory loss, brain damage, and
Australians don't need an economist to tell them they're hurting at the petrol pump. They feel it every time they pull into a service station, every time they rethink a planned holiday, or every time they've had to squeeze another household bill to fill the tank. But the cost
A new survey reveals a striking disconnect in how Americans think about autism research. While nearly everyone agrees that studying the autistic brain is essential, most people are unaware that brain donation after death is a key part of making that research possible. Unlike
On a calm summer's morning in southern Australia, the water can look deceptively clear, until you see thousands of gelatinous shapes washing ashore. In January, thousands of pink lion's mane jellyfish washed into Port Phillip Bay, prompting beach warnings and startling swimmers
Some 39 Australian mammals have gone extinct since Australia was colonized in 1788.
Using new genetic markers, fruit breeders can now tell whether grapes will be seedless and self-pollinating even years before vines bear fruit. The approach will save time and resources in the pursuit of creating flavorful new grape varieties, including the major challenge of
More than 3,000 fish species have been caught in bottom trawls, with estimates suggesting the true number could be nearly double, according to the world's first global inventory.
When a drought turns into an urban water crisis, a city's first step is often to limit lawn watering and launch a campaign to encourage everyone to conserve. It might raise water-use rates or offer incentives for installing low-flow devices.
A study published in Cell Research advances a central idea in stem cell biology by identifying a checkpoint that controls the identity of many different types of stem cells across developmental stages. For nearly two decades, scientists have understood that stem cell
Online comments can shape how social media content about politics is perceived, even when people's opinions are hard to change, a new study shows. The new research suggests that while attitudes may be stable, the way people interpret political messages can still shift depending
A shutdown of the Atlantic Meridional Overturning Circulation (AMOC) could trigger a substantial release of stored ocean carbon into the atmosphere over hundreds of years, according to a new study that simulated such a collapse under stable climate conditions. This would add
Sustainability has become something of a buzzword over the years. From the clothes we wear and the energy that powers our homes to the way we live our lives, the idea of sustainable production and consumption has become commonplace.
Tropical rainforests are home to almost two-thirds of all vertebrate species and three-quarters of all tree species: they are the most species-rich terrestrial ecosystem on Earth. However, over half of these diverse rainforests have already been cleared, and their area
Excavation of a council house at the major Lowland Maya center of Ucanal, Guatemala, reveals how the public gained some influence over Maya politics more than 1,000 years ago. These colonnaded, open halls were likely council houses, where political leaders met to deliberate on
Musicians around the world agree on one thing: streaming platforms are essential for their careers. Most also agree on another: they don't pay enough. A new report from the Oxford Internet Institute and the University of Groningen captures this contradiction across five
Every day, fish caught in oceans and seas around the world pass through a long journey before reaching supermarkets, restaurants, and home kitchens. Along the way, their freshness steadily declines, often in ways that are difficult to detect. Now imagine being able to measure
From space, Earth's populated areas glow on the otherwise "black marble" of the planet at night. For decades, scientists assumed this glow was steadily increasing as the world developed. However, a new study published in Nature flips this narrative.
An international team of researchers, led by scientists from the University of California, Irvine, has demonstrated a fundamentally new way to make silicon emit light—overcoming one of the most persistent limitations in modern electronics and photonics. In their work appearing
A specific protein controls mRNA transport in fungi and distinguishes important from unimportant binding sites in the transported mRNAs. Researchers from Würzburg and Düsseldorf have discovered this mechanism.
Earlier this year, I published a paper on the ethics of researching military populations. The core argument was straightforward: the standard rules researchers follow to protect participants—for example, informed consent and voluntary participation—don't work the same in an
The Artemis II spacecraft is due to splash down on April 10, and NASA officials and the astronauts onboard are gearing up for that return
A study of nearly 200,000 Amazon reviews shows that the usefulness of online product reviews depends not only on what is said, but on how the information is structured. The researchers, from the Universities of Cambridge and Queensland, studied Amazon reviews for products
Undergraduate students at Penn State Brandywine developed an environmentally friendly and easy method to synthesize compounds from plant-derived molecules for potential use in therapeutics. Their work, conducted under the supervision of Penn State Brandywine Assistant Professor
