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…
For decades, many evolutionary biologists have believed that most genetic changes shaping genes and proteins are neutral. Under this view, mutations are usually neither helpful nor harmful, allowing them to spread quietly without being strongly favored or rejected by natural selection. A new study from the University of Michigan challenges…
Engineers from Stanford University, Carnegie Mellon University, University of Pennsylvania, and the Massachusetts Institute of Technology worked with SkyWater Technology, the largest exclusively U.S. based pure play semiconductor foundry, to create a new multilayer computer chip. The team says its architecture could mark a major shift in AI hardware and…
A global research team led by the company Aivocode, working with scientists from the Institute for Advanced Chemistry of Catalonia (IQAC) of the Spanish National Research Council (CSIC), reports that a small compound has a strong protective effect in mouse models of traumatic brain injury. The compound is a peptide…
Researchers led by RMIT University have developed extremely small particles called nanodots that can destroy cancer cells while largely leaving healthy cells unharmed. The particles are made from a metal-based compound and represent a possible new direction for cancer treatment research. The work is still in its early stages and…
The genes of your roommate may be shaping the bacteria in your gut, and your genes may be influencing theirs, according to a rat study published on December 18 in Nature Communications. By examining more than four thousand rats, researchers found that the makeup of the gut microbiome is affected…
In 1798, officer and physicist Benjamin Thompson (a.k.a. Count Rumford) made a simple but powerful observation while watching cannon barrels being drilled in Munich. The metal heated up continuously during the process, leading him to conclude that heat is not a physical substance. Instead, it can be produced endlessly through…
Researchers at the University of Iowa have identified a new way to “purify” photons, a development that could improve both the performance and security of light based quantum technologies. By refining how single particles of light are produced, the approach aims to overcome long standing limitations in optical quantum systems.…
A research team from MIT and Stanford University has developed a new technique designed to push the immune system to go after tumor cells. The strategy is aimed at helping cancer immunotherapy succeed in far more patients than it does today. At the center of the work is a way…
The Hațeg Basin in Transylvania has long been known around the world for its dinosaur fossils, uncovered at dozens of sites over the last hundred years. Even so, complete dinosaur discoveries are usually uncommon across the region. That pattern changed with the identification of a newly studied site where scientists…
Scientists have identified a genetic mechanism that could point to new ways of treating a rare but deadly fungal infection that has forced multiple hospital intensive care units to shut down. The finding offers early hope against a pathogen that has been difficult to control and nearly impossible to treat…
