Researchers at the LKS Faculty of Medicine of the University of Hong Kong (HKUMed) have developed an artificial intelligence tool that may help predict serious cardiovascular problems many years before symptoms appear. The system, known as CardiOmicScore, uses information from a single blood test to estimate a person’s future risk…
A PhD student in Sydney has produced cosmic dust from scratch by recreating a small piece of the universe inside a laboratory bottle. The experiment offers new clues about how some of the chemical ingredients associated with life could have developed before Earth even formed. Linda Losurdo, a PhD candidate…
Do you sometimes notice a deep buzzing or humming noise that seems to have no identifiable source? If so, you may be among the estimated 2-4 percent of people worldwide who experience this unusual sound. Researchers have spent decades trying to determine where it originates. For some, the noise is…
Coffee has repeatedly been associated with longer life and a lower risk of several chronic illnesses. Even so, scientists have not fully understood the biological processes that might explain those benefits. New findings from the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) point to one possible answer.…
A newly identified branch of the marsupial family tree is adding a surprising twist to the history of Australia’s most distinctive mammals. The finding suggests that their evolution was more complicated, and more mysterious, than scientists previously understood. Marsupials first reached Australia more than 55 million years ago. Since then,…
A rare type of meteorite known as a CO chondrite was likely the object that slammed into Earth 66 million years ago and triggered the extinction of about 75 percent of all species, including every non-avian dinosaur. Researchers from the University of British Columbia (UBC), Paris, Brussels, and Vienna reached…
A widely available antidepressant may provide meaningful relief for people experiencing persistent fatigue from long COVID, according to a global clinical trial co-led by McMaster University. Researchers found that fluvoxamine (sold under the brand name Luvox), an inexpensive medication already commonly used to treat depression and other conditions, reduced fatigue…
Several widely used sugar substitutes may be associated with faster declines in memory and thinking skills over time, according to research published in Neurology, the medical journal of the American Academy of Neurology. The study followed nearly 13,000 adults and examined seven sweeteners that contain little or no calories. People…
A violent collision in the main asteroid belt may have triggered a prolonged wave of impacts across the inner solar system about 800 million years ago, according to a study led by the Southwest Research Institute. The researchers propose that the breakup of the parent object that formed the Eulalia…
Scientists have discovered that one of the most extreme volcanic events in Earth’s history did more than build a massive underwater plateau. It also altered the structure and chemistry of the oceanic plate beneath it. A research team led by Lecturer Azusa Shito of Okayama University of Science, working with…
A 12 week intermittent fasting program may help people maintain weight loss for at least a year after the structured intervention ends, according to research involving the University of Granada (UGR). Published in Clinical Nutrition, the study followed 99 adults who were overweight or obese. Half of the participants were…
New observations from the James Webb Space Telescope, or JWST, are giving astronomers their clearest look yet at how supermassive black holes obtain the gas they need to grow. The images reveal long strands of gas linking a galaxy’s hot outer atmosphere to a rapidly rotating disk surrounding its central…
A Mediterranean-style diet may influence aging through an unexpected biological pathway involving tiny proteins produced inside mitochondria, according to a new study led by researchers at the USC Leonard Davis School of Gerontology. Mitochondria are best known as the structures that generate energy inside cells, but scientists increasingly recognize that…
Terraforming is the process of reshaping a planet or moon so it can support humans and other Earth-like life. In theory, that means changing an alien world’s atmosphere, climate, and surface to more closely resemble Earth’s by adding oxygen, creating stable bodies of liquid water, and producing temperatures suitable for…
Every summer, lawns fill with colorful “silly sprinklers,” whose looping and twisting tubes send water spraying in unusual patterns. Their designs may look playful, but researchers have now used these backyard devices to investigate a serious and decades-old question in physics. The mystery is known as Feynman’s Sprinkler Problem. It…
Nanoplastics are already a concern because people may ingest them directly, but new research points to another possible danger. These tiny plastic particles may also make harmful bacteria more difficult to control. In a study published in Water Research, Virginia Tech researcher Jingqiu Liao and an international team found that…
Human evolution is closely associated with the development of a much larger brain. New research suggests that greater exposure to estrogen before birth may have contributed to that expansion, and that a possible trace of this hormonal influence can be seen in the relative lengths of a person’s fingers. Professor…
A major genomic analysis is changing scientists’ understanding of koala evolution. The research indicates that koalas (Phascolarctos cinereus) underwent a severe population decline about 100,000 years ago, well before humans reached Australia. Every koala alive today appears to descend from a single ancestral population that endured dramatic environmental shifts, including…
Commonly used sweeteners can directly interfere with the growth of bacteria that help support a healthy gut, according to laboratory research from the University of Cambridge. The strongest effect appeared when researchers combined isosteviol, a sweetener used by the food and beverage industry, with the antidepressant duloxetine. Together, the two…
Some breakthroughs in physics come from brand new inventions. Others begin with a new theory. But many advances happen when researchers combine familiar technologies in an unexpected way and create something more powerful than the individual parts. That strategy could be especially valuable in the search for weakly interacting particles,…
Researchers at King’s College London have identified a promising new strategy for tackling Alzheimer’s disease by targeting several of the disease’s earliest biological changes at the same time. Their study found that KCL-286, an experimental drug originally developed for spinal cord injury that has already passed Phase 1 safety trials,…
Scientists have uncovered how a toxin produced by a common gut bacterium gains access to colon cells, solving a mystery that has puzzled researchers for more than 15 years. The discovery not only explains how the toxin begins damaging the colon, but also points to a possible new way to…
The U.S. Centers for Disease Control and Prevention (CDC) is working with state and federal health agencies to investigate several outbreaks of cyclosporiasis. Efforts to determine and confirm the sources of these outbreaks are still underway. A large outbreak of cyclosporiasis has been reported in at least four Midwestern states.…
Researchers at the City College of New York are charting a fast-growing area of quantum science centered on materials only a few atoms thick. In these systems, light, electric charge, and magnetism are closely connected rather than behaving independently. The work comes from physicist Vinod M. Menon’s Laboratory for Nano…
Imagine the year 2158. You’re pursuing a PhD in planetary volcanology at the University of Utopia Planitia on Mars, surviving on freeze dried ramen while searching for the perfect exoplanet to study. After finishing your research on Jupiter’s volcanic moon Io, you need a rocky world beyond our solar system…
People struggling with depression often continue to experience memory problems, poor concentration, and mental “brain fog” even after their mood improves. Now, researchers say an existing prescription drug approved to treat chronic constipation may also help improve those lingering cognitive symptoms. The findings, published in Psychological Medicine, come from an…
Brain cells continually pull material from the fluid around them, including nutrients, signaling molecules, and fragments of their own outer surfaces. This process, called endocytosis, supports learning, memory, and the routine maintenance of neurons. Penn State researchers have now identified a previously unrecognized structure that may control much of this…
A colorful pet gecko that is unusually prone to developing cancer could become an important new tool for researchers studying how tumors form and spread. Scientists say the animal’s naturally occurring cancers may offer valuable insights into why some species are highly vulnerable to the disease while others are remarkably…
The Black Sea, which lies between Europe and Asia and connects to the Mediterranean through a series of waterways, is known for its dark waters. But every spring and summer, it undergoes a remarkable transformation, with large areas turning a vivid turquoise. On June 22, 2026, NASA’s PACE (Plankton, Aerosol,…
Archaeologists working at the ancient Egyptian site of Oxyrhynchus have made a remarkable discovery: a papyrus containing a passage from Homer’s Iliad was found inside a Roman-era mummy dating back about 1,600 years. Researchers say it is the first known case in archaeological history in which a Greek literary text…
