Choosing the diet version of a favorite soda often means consuming non-nutritive sweeteners. These additives provide sweetness without the calories found in sugar. However, some health organizations have begun raising questions about their possible long-term effects, including whether they may disrupt energy metabolism and eventually contribute to a higher risk…
Scientists at the University at Buffalo have developed an injectable hydrogel designed to keep osteoarthritis treatments inside the joint for much longer than conventional injections. After a single minimally invasive injection, the material changes from a liquid into a smooth, lubricating semisolid depot at body temperature. Once in place, it…
A simple measurement around the waist could reveal important health risks that weight alone may miss, according to new research from Rutgers Health. The study, published in JAMA Network Open, found that measuring waist circumference, either by itself or together with body mass index (BMI), was about as effective as…
Uncovering this hidden structure could eventually allow researchers to design superconducting materials and devices with greater control and precision. As scientists pursue quantum computers, ultra-efficient electronics, and other advanced technologies, a detailed understanding of how electrons behave inside superconductors will become increasingly important. ng-standing puzzle about their behavior and offers…
Future quantum computers may depend on the ability to connect widely separated modules through distributed entanglement. Until now, creating this kind of connection has generally required active control and repeated measurements. Physicists at the Institute of Science and Technology Austria (ISTA) have now demonstrated a fully autonomous alternative based on…
A long-standing picture of brain evolution as newer, rational layers stacked on top of an ancient “lizard brain” may be deeply misleading. Researchers found that evolution instead appears to balance two competing styles of brain wiring, expanding one while shrinking the other depending on what an animal needs to survive.…
New research suggests that whatever scientists ultimately discover about the last common ancestor of humans and chimpanzees, one characteristic may be difficult to dispute: it was probably capable of climbing trees. Humans and chimpanzees went their separate evolutionary ways between 6 and 7 million years ago, when they diverged from…
Excessive alcohol use can interfere with one of the liver’s most remarkable abilities: repairing and rebuilding itself after injury. New research suggests that alcohol related damage can leave liver cells trapped in an abnormal middle state, unable to function normally or complete the regeneration process, even after a person stops…
NASA’s Nancy Grace Roman Space Telescope has begun a three-month journey covering roughly one million miles as it travels toward its final orbit. The observatory lifted off at 7:26 a.m. EDT Sunday aboard a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Once…
The ingredients needed to build rocky planets may have appeared as early as 100 million years after the Big Bang, according to new research from the University of Portsmouth. That would place the beginnings of planet formation remarkably close to the dawn of the Universe, even before the first galaxies…
Researchers at the University of Hong Kong (HKU) have discovered that ultrathin, highly flexible diamond membranes can produce a measurable piezoelectric response, challenging a scientific assumption that has stood for more than a century. The work was led by Professor Zhiqin Chu, Associate Professor in the Department of Electrical and…
A remarkable set of fossil footprints from northern Kenya is offering scientists a rare glimpse of how an extinct human relative may have moved and interacted about 1.4 million years ago. The tracks, preserved near an ancient lakeshore, appear to record eight Paranthropus boisei individuals occupying the same place at…
Physics allows for black holes far smaller than the enormous objects typically found at the centers of galaxies or created when massive stars collapse. Under the right conditions, microscopic black holes could also form when spacetime enters an unusual critical state and organizes into a repeating, crystal-like pattern. Researchers from…
A combination of omega-3 and low-dose acetylsalicylic acid (ASA) performed about as well as antibiotics in a yearlong study of people with severe periodontitis, raising the possibility of an alternative treatment for some patients. The research was conducted by scientists affiliated with Albert Einstein Israelite Hospital, Guarulhos University (UNG), the…
Scientists used a new error correction strategy to encode 70 logical qubits and tackle a problem considered classically intractable. The quantum computation was completed in about 15 minutes, while leading classical computing methods would require an impractical amount of time to perform the same task. IBM and researchers at the…
Using an in-home HEPA purifier for one month spurs a small but significant improvement in brain function in adults age 40 and older. That’s the result of a new study we co-authored in the journal Scientific Reports. HEPA purifiers – HEPA stands for high efficiency particulate air – remove particulate…
Glacial earthquakes are a special type of earthquake generated in cold, icy regions. First discovered in the northern hemisphere more than 20 years ago, these quakes occur when huge chunks of ice fall from glaciers into the sea. Until now, only a very few have been found in the Antarctic.…
Researchers have uncovered a major temperature imbalance deep inside Mars, with the planet’s southern interior appearing significantly hotter than its northern half. Gravity measurements suggest that the interior beneath Mars’s southern hemisphere is about 200 to 400 degrees Celsius warmer than the north and may be partially molten. The finding…
Nanocrystals have become an important part of modern materials science, with quantum dots helping inspire the 2023 Nobel Prize in Chemistry. Yet despite their enormous potential, researchers have only been able to produce these microscopic crystals from a relatively narrow range of materials. Now, chemists at the University of Chicago…
An international research team has identified seven previously undescribed species of Madagascar’s elusive diamond frogs (Rhombophryne), adding new evidence that this unusual amphibian group is far more diverse than scientists once realized. Accurately identifying species and understanding where they live are essential for measuring biodiversity and protecting it. To sort…
For years, archaeologists have debated why some ancient Egyptian princesses were buried with weapons. The bows, arrows, daggers, and maces found in their tombs were often interpreted as ceremonial objects rather than equipment the women had actually used. A new examination of royal mummies from Egypt’s Middle Kingdom now suggests…
Scientists have found a way to grow Spirulina that produces biologically active vitamin B12 at levels comparable to beef, potentially overcoming one of the biggest nutritional limitations of this widely promoted algae. The research, published in the scientific journal Discover Food, was led by Dr. Asaf Tzachor, Founder and Academic…
A new seismic analysis of the Juan de Fuca tectonic plate beneath northern Oregon suggests the subducting slab lies closer to the surface than scientists previously believed. The finding could affect estimates of how strongly the region might shake during a future Cascadia megathrust earthquake. The Juan de Fuca plate…
Two remarkably successful theories explain nearly everything we observe in the universe, from tiny atoms and molecules to planets, stars, and galaxies. Quantum mechanics describes the behavior of matter at very small scales, while Einstein’s theory of gravity explains how stars and black holes move and how the Universe expands.…
Immunotherapies such as CAR T-cell therapy were originally developed mainly to fight cancer. But scientists are now investigating whether these personalized treatments, made from a patient’s own immune cells, could also help treat or even potentially cure autoimmune diseases. Researchers at Charité – Universitätsmedizin Berlin have now tested CAR T-cell…
A very low-carbohydrate, high-fat diet may provide stronger metabolic benefits for people with obesity than either a Mediterranean diet or a low-fat diet, according to a clinical trial published August 27 in the Cell Press journal Cell Metabolism. After four to five months on a ketogenic (or “Keto”) diet, about…
Dogs and humans may share some of the same biological patterns tied to lifespan, according to new research from the Dog Aging Project. The finding could give scientists a useful new way to investigate how aging works in both species. In a study recently published in The Journals of Gerontology,…
Virginia Tech chemist and chemical engineer Guoliang “Greg” Liu and his research team have developed a method for transforming polyvinyl chloride (PVC) into polyalphaolefin, an important ingredient used in lubricants including engine oil. Published Aug. 5 in Nature, the work could offer a way to address two separate environmental problems…
An international team of astrophysicists says the universe is still expanding at an accelerating rate, rejecting recent claims that cosmic expansion may have begun to slow. The researchers challenged a study published last year claiming the growth of the universe is slowing. They argue that the standard interpretation remains intact:…
Long-term use of melatonin, a widely used sleep supplement, was linked to a higher risk of heart failure, hospitalization for heart failure, and death from any cause among people with chronic insomnia, according to preliminary research presented at the American Heart Association’s Scientific Sessions 2025. The findings do not prove…
