A research team led by scientists at the University of Ottawa has produced a new set of detailed 3D models that map temperatures deep beneath Greenland and northeastern Canada. These models shed light on how the region formed over millions of years and help explain how Greenland’s massive ice sheet…
Scientists have now clarified how deuterons form under extreme conditions. Protons and neutrons needed to create these tiny nuclei are released when extremely short-lived, high-energy particle states decay (so-called resonances). Once freed, the particles can join together to form deuterons. The same process also explains how antideuterons, made of antimatter,…
Researchers at Stanford Medicine have identified the biological steps that explain how mRNA-based COVID-19 vaccines can, in rare cases, lead to heart inflammation in some adolescent and young adult males. Their work also points to a potential strategy for lowering that risk. By combining modern laboratory techniques with previously published…
Researchers at UBC Okanagan have figured out how plants make mitraphylline, a rare natural substance that has drawn attention for its potential role in fighting cancer. Mitraphylline is part of a small and unusual family of plant chemicals known as spirooxindole alkaloids. These molecules are defined by their distinctive twisted…
Neutrinos are extraordinarily difficult to detect, yet they are among the most abundant matter particles in the Universe. According to the Standard Model of particle physics, there are three known kinds. That picture changed when scientists discovered neutrino oscillations, a phenomenon showing that neutrinos have mass and can switch between…
The DNA inside our cells is under constant attack. One of the most dangerous forms of damage is a double-strand break, which happens when both strands of the DNA helix are cut at the same time. Under normal conditions, healthy cells rely on highly accurate repair systems to fix this…
Before humans can make the long trip to another world, scientists must identify a safe and practical place to land. New research led by a University of Mississippi scientist suggests one region on Mars may meet many of the requirements for future human missions. Erica Luzzi, a planetary geologist and…
An international group of astronomers has uncovered strong evidence suggesting that the material surrounding supermassive black holes has not remained the same throughout the history of the universe. The findings indicate that the structure and behavior of this matter may have shifted over billions of years. Led by researchers at…
Scientists at the University of Otago, Faculty of Medicine — Christchurch Ōtautahi, have identified a direct connection between how much vitamin C people eat and how well their skin produces collagen and renews itself. The findings show that skin health responds measurably to dietary vitamin C, not just topical treatments.…
Something unexpected is happening inside a material called platinum-bismuth-two (PtBi2). According to a new study from researchers at IFW Dresden and the Cluster of Excellence ct.qmat, this shiny gray crystal may look ordinary, but the electrons inside it behave in ways scientists have never observed before. In earlier work published…
Researchers have achieved a significant step forward in quantum computing by developing a device that is almost 100 times thinner than the width of a human hair. The work, published in the journal Nature Communications, introduces a new type of optical phase modulator designed to precisely control laser light. This…
An international research team from NIMS, The University of Tokyo, Kyoto Institute of Technology, and Tohoku University has shown that ultra-thin films of ruthenium dioxide (RuO2) display altermagnetism. This property defines what scientists now recognize as a third fundamental category of magnetic materials. Altermagnets are drawing growing interest because they…
People constantly take in information from their surroundings, including visual details and background sounds. Over time, the brain learns to connect these cues with what usually happens next. For example, a familiar sign, sound, or setting can signal whether a choice is likely to lead to a reward or a…
Researchers from the Institut Pasteur and Inserm have found that when mother mice consume dietary emulsifiers, it can negatively affect the gut microbiota of their offspring. These early changes in gut bacteria are linked to a higher risk of chronic inflammatory bowel conditions and obesity later in life. The findings…
Astronomers at the University of Hawaiʻi Institute for Astronomy (IfA) have pieced together the dramatic history of a distant red giant by studying subtle changes in its light. Tiny fluctuations in brightness reveal that the star may have collided and merged with another star long ago, a violent event that…
Around 4.6 billion years ago, Earth looked nothing like the calm, blue world we see today. Repeated and powerful impacts from space kept the planet’s surface and interior in a turbulent, molten state. Much of Earth was covered by a global ocean of magma, with temperatures so extreme that liquid…
Temporal lobe epilepsy causes repeated seizures and often interferes with memory and thinking. New research now suggests that this condition is also tied to early aging in certain brain cells. Scientists at Georgetown University Medical Center report that eliminating these aging cells in mice led to fewer seizures, better memory,…
Scientists have confirmed the rediscovery of Moema claudiae, a rare seasonal killifish species in Bolivia that had been considered possibly extinct. The finding renews hope for protecting this unusual fish and the fragile wetland ecosystems it depends on. The species had not been observed for more than 20 years. Its…
A large review of existing research suggests that tramadol, a strong opioid commonly prescribed for chronic pain, does not provide much meaningful relief. The analysis, published online in BMJ Evidence Based Medicine, found that while tramadol can reduce pain, the improvement is modest and falls below levels typically considered clinically…
Ocean regions that fuel the planet’s most powerful hurricanes and typhoons are heating up in the North Atlantic and Western Pacific. These changes are being driven not just by warmer surface waters, but by heat that now extends far below the ocean surface. New research suggests that human-caused climate change…
An international research team led by the University of Oxford has identified one of the largest rotating structures ever observed. The object is a razor thin chain of galaxies embedded within a vast cosmic filament located about 140 million light years from Earth. The results were published in Monthly Notices…
This Christmas, the universe shows off its own glowing Christmas tree, built from newborn stars deep in the Milky Way. Credit & Copyright: Michael Kalika NGC 2264 is a large and active region of space where new stars are forming, located about 2,700 light years from Earth. It lies within…
A potential new way to treat reduced brain blood flow and certain forms of dementia is beginning to emerge. Scientists at the University of Vermont Robert Larner, M.D. College of Medicine have uncovered new details about how blood circulation in the brain is controlled and how vascular problems might be…
Scientists still have much to learn about what small asteroids are made of. These rocky bodies may contain valuable metals, ancient material left over from the formation of the solar system, and chemical clues that reveal the history of their original parent bodies. Because of this, they are increasingly viewed…
A research team at Rice University, working with international collaborators, has created the first environmentally friendly technology that can quickly trap and break down toxic “forever chemicals” (PFAS) in water. The results, published recently in Advanced Materials, represent a meaningful advance against one of the most stubborn pollution threats worldwide.…
A study reveals that restoring the brain’s energy balance may not just slow Alzheimer’s — but actually reverse it. For more than a century, Alzheimer’s disease has been widely viewed as permanent and untreatable once it begins. As a result, most research has focused on preventing the disease or slowing…
eople, the holidays often bring joyful indulgence, followed by regret and ambitious New Year’s resolutions to eat better. A recent study from the University of British Columbia suggests moderation should not be a seasonal goal but a long-term one. The research found that 44 percent of the global population would…
Today’s arguments about consciousness often get stuck between two firm camps. One is computational functionalism, which says thinking can be fully described as abstract information processing. If a system has the right functional organization (regardless of the material it runs on), it should produce consciousness. The other is biological naturalism,…
After ChatGPT became widely available in late 2022, many researchers started telling colleagues they could get more done with these new artificial intelligence tools. At the same time, journal editors reported a surge of smoothly written submissions that did not seem to add much scientific value. A new Cornell study…
Roughly three centuries ago, Swedish naturalist Carl Linnaeus set out to catalog and name every living organism he could find. He is now widely regarded as the founder of modern taxonomy after introducing the binomial naming system and formally describing more than 10,000 species of plants and animals. Scientists have…
