A low dose of digoxin may help people with heart failure avoid hospitalization and reduce the risk of death, according to three studies led by UMCG cardiologists Dirk Jan van Veldhuisen, Kevin Damman, and Peter van der Meer. The researchers believe the new findings could eventually influence heart failure treatment…
Physical activity and healthy blood sugar levels during midlife may be linked to a significantly slower decline in thinking abilities later in life, according to new research from UT Health San Antonio, the academic health center of The University of Texas at San Antonio. The findings suggest that exercise may…
Growing older has plenty of upsides – but achy joints is not one of them. As we age, the joints that once handled every bend and fall start to weaken. This is because the amount of cartilage, a tough but flexible kind of connective tissue, and fluid in your joints…
New findings from the STAR detector at the Relativistic Heavy Ion Collider (RHIC) are challenging a familiar picture of what gives protons one of their defining quantum properties. The results suggest that gluons, the particles that act as the glue holding quarks together, may play a key role in carrying…
New Australian research is shedding light on why walking often becomes slower and more tiring with age. The findings suggest that the body gradually gives up some movement efficiency in favor of staying stable and upright. Led by researchers at Flinders University and the University of Canberra, the study found…
Researchers at La Brea Tar Pits have identified a previously unknown amphibian that lived in Ice Age Los Angeles. The extinct spadefoot toad, now named Spea labreae, represents the first new extinct amphibian species discovered from the famous fossil site. The find is exceptionally rare. Only one other extinct Pleistocene…
A massive star has been torn apart and gradually consumed by a black hole in a spectacular event that scientists compared to “preparing a snack for lunch.” Astronomers around the world observed the extreme encounter, and the event was presented at the AAS conference in Phoenix, Arizona. Researchers described the…
Viruses that remain in the body for years, including Epstein-Barr, cytomegalovirus (CMV), and herpes virus, are extremely common. In many people, they cause no symptoms and appear to be harmless. But growing evidence suggests that when these dormant viruses become active again, they may play a role in autoimmune diseases…
Rising levels of carbon dioxide in the atmosphere may already be influencing human biology. New research has identified long-term changes in blood chemistry that appear to track rising atmospheric CO2, raising concerns that an important blood marker could approach the upper end of its healthy range within the next several…
Plant based diets support health in several ways, including benefits for the gut, immune system, metabolism, and cardiovascular system. Part of that effect comes from encouraging a diverse population of bacteria in the intestines. Scientists have long known that dietary fiber contributes to these benefits because gut microbes help break…
Researchers from Okayama University of Science, Tokyo City University, the Natural History Museum, Kishiwada City (Osaka Prefecture), and other institutions have uncovered four fossil bones that went unrecognized for roughly three decades. The bones were found inside rock containing mosasaur remains collected in Kishiwada City, Osaka Prefecture. One of the…
A chemical commonly used to preserve food has been linked to a recent increase in suicide deaths in the UK, with young people and boys and men accounting for a disproportionately large share of cases. The findings come from a comprehensive analysis of available data from 2019-24 published in the…
For more than six decades, evolutionary biologists have debated whether an unusual genetic system shared by ants, bees and wasps helped drive one of nature’s most sophisticated forms of social organization: eusociality. In eusocial colonies, reproduction is divided between queens and workers, creating highly cooperative societies with specialized roles. New…
Cambridge researchers have uncovered why both activating and blocking the same brain receptor can promote weight loss. The findings may help scientists develop obesity treatments that are more effective and potentially work better in combination. The mouse study, published in Nature Metabolism, found that the outcome depends on which part…
For decades, scientists have generally viewed the brain’s immune system as largely separate from the immune defenses operating throughout the rest of the body. The brain has its own specialized immune cells, along with the blood-brain barrier, which restricts many substances and cells from entering brain tissue. New research from…
Even after a nuclear reactor is switched off, activity continues deep inside its core. Long-lived radioactive fission products keep decaying for months or even years, releasing a weak stream of particles called antineutrinos. (Anti)neutrinos are the lightest and most elusive known particles in the Universe, and they can pass through…
A newly developed superconducting quantum heat engine could deepen our understanding of thermodynamics while helping advance technologies needed for quantum computers with very large numbers of qubits. Scientists are getting a clearer picture of how thermodynamics behaves in the quantum world, and that progress could benefit both quantum technology and…
New research from the University of East Anglia and the Norfolk and Norwich University Hospital suggests that something as simple as choosing the stairs could contribute to a longer life. The large study found that people who regularly climbed stairs had a substantially lower risk of dying from cardiovascular disease.…
When laboratory mice experience brain damage, e.g., from an injection, Jan Deussing repeatedly notices the same response. A particular group of cells appears and becomes active around the damaged area. Although Deussing, a research group leader and experienced neurobiologist, had observed the phenomenon many times, he did not know exactly…
A large study has found that women who used hormone therapy later in life had a lower risk of developing dementia. The findings were published August 12, 2026, in Neurology, the medical journal of the American Academy of Neurology. Researchers emphasized that the results show an association and do not…
For decades, scientists generally assumed that fossilization destroyed the original organic molecules once present in bones, teeth, and other tissues. Under that view, proteins and other biological materials were not expected to survive for tens of millions of years. New research led by the University of Liverpool now provides strong…
For years, climate scientists have warned that the Atlantic Meridional Overturning Circulation (AMOC) could eventually shut down if global temperatures rise too far. New findings from researchers at Utrecht University suggest that temperature alone does not determine the fate of this major ocean circulation system. The speed at which the…
In 1989, Voyager 2 discovered six previously unknown moons around Neptune. Five of them are tiny satellites that travel just beyond the planet’s main rings. Their small size and distant location have made them extremely difficult to investigate from Earth. Now, NASA’s James Webb Space Telescope (JWST) has given scientists…
The Sloan Digital Sky Survey V has taken a major step toward mapping the sky on a truly global scale with Data Release 20. Known as DR20, the release includes the first optical (BOSS) SDSS-V spectra collected from the Southern Hemisphere, greatly expanding the survey beyond the groundwork established in…
A large study involving more than 5,500 adults over age 50 has identified a potentially dangerous combination of health risks. People who had both abdominal obesity and vitamin D deficiency faced a 123% higher risk of death compared with those who had neither condition. The findings, published in the journal…
Congenital heart disease is the most common birth defect, affecting about 1 in 100 babies born each year. The condition can have many causes, including changes involving TBX5, a gene that plays a critical role in building the heart. In some cases, a child has only one working copy of…
NASA’s Perseverance Mars rover has captured a remarkable celestial sight: Earth briefly vanishing behind Phobos in the evening sky of Mars. A newly released sequence of images shows Earth as a tiny point of light while Phobos, the larger of Mars’ two moons, moves across the sky and passes directly…
Astronomers from MIT and other institutions have identified an exceptionally bright red object dating back to the early universe. At first glance, it resembles an enormous star with dimensions comparable to our solar system. Its energy output, however, is extraordinary. The object is producing roughly 100 billion times more energy…
Most of us think of orange juice as a simple breakfast habit, something you pour without much thought. Yet scientists are discovering that this everyday drink may be doing far more in the body than quenching thirst. A recent study has shown that regular orange juice consumption can influence the…
Some cynodonts may have started giving birth to live young far earlier in evolutionary history than scientists once believed. A new study published in Frontiers in Mammal Science presents the first compelling evidence that at least some cynodonts may have been viviparous — meaning they gave birth to live offspring.…
