Hidden household toxin triples liver disease risk, study finds

Liver disease most often develops due to one of three major causes: excessive alcohol use, the buildup of fat in the liver associated with obesity, diabetes, and high cholesterol, or viral infections such as hepatitis B and C. Researchers from Keck Medicine of USC have identified another potential cause of…

New study finds Ozempic and Mounjaro protect the heart too

Weight-loss drugs Ozempic and Mounjaro deliver impressive heart protection for people with type 2 diabetes. Large real-world study finds new GLP-1 drugs help protect the heart in people with cardiovascular risk. Clear evidence shows these medications support heart health beyond their weight-loss effects. Semaglutide (Ozempic) and tirzepatide (Mounjaro) offer similar…

Scientists just found a material that beats diamond at its own game

Researchers at the University of Houston have achieved a major scientific milestone in the study of heat transfer. Their new findings overturn long-standing assumptions about thermal conductivity and reveal that boron arsenide (BAs) can conduct heat more effectively than diamond, which has long been considered the benchmark among isotropic materials.…

A 540-million-year-old fossil is rewriting evolution

Recently, Halloween may have brought thoughts of skeletons, but the true “skeleton age” began long ago during the early Cambrian Period, roughly 538 to 506 million years ago. During this transformative era, many of Earth’s major animal groups independently figured out how to create mineralized skeletons or shells. They typically…

Scientists find 15 gut bacteria that may drive heart disease

Heart disease remains the world’s top killer, claiming more lives each year than any other condition. Scientists are uncovering how gut microbes may influence coronary artery disease (CAD), one of the most common and serious forms of heart disease. A research team in Seoul has identified 15 specific bacterial species…

Wegovy and Ozempic tied to dramatically lower cancer deaths

A new study from the University of California San Diego suggests that glucagon-like peptide-1 (GLP-1) receptor agonists, a class of medications originally developed for type 2 diabetes, may have benefits that extend far beyond blood sugar and weight management. These drugs, which include semaglutide (sold as Ozempic and Wegovy) and…

NASA's Webb finds life’s building blocks frozen in a galaxy next door

In a finding that could change how scientists understand the spread of life’s ingredients across space, astronomers have detected large organic molecules frozen in ice around a forming star called ST6 in a galaxy beyond the Milky Way. Using the James Webb Space Telescope’s (JWST) Mid-Infrared Instrument (MIRI), the research…

Earth is slowly peeling its continents from below, fueling ocean volcanoes

Earth scientists have uncovered a slow and surprising process beneath our planet’s surface that helps fuel volcanic activity in the oceans. Researchers from the University of Southampton found that fragments of continents are gradually stripped away from below and drawn into the oceanic mantle — the hot, mostly solid layer…

Scientists shocked as bumblebees learn to read simple “Morse code”

Researchers at Queen Mary University of London have discovered that an insect, the bumblebee Bombus terrestris, can choose where to gather food by recognizing how long a visual signal lasts. In Morse code, short flashes or “dots” stand for the letter “E,” while longer flashes or “dashes” represent the letter…

Astronomers stunned by three Earth-sized planets orbiting two suns

An international group of scientists has confirmed the discovery of three Earth-sized planets within the binary stellar system known as TOI-2267, located roughly 190 light-years from Earth. The finding, published in Astronomy & Astrophysics, offers new insight into how planets can form and remain stable in double-star systems, which were…

What brain scans reveal about soccer fans’ passion and rage

Researchers studying the brains of soccer fans found that certain areas of the brain light up when people watch matches featuring their favorite team. These neural circuits trigger strong emotional reactions — both positive and negative — depending on how the game unfolds. The findings, published in Radiology (a journal…

The rarest element on Earth could revolutionize cancer treatment

Astatine is the rarest naturally occurring element on Earth and among the least explored in the periodic table. True to its Greek name meaning “unstable,” it exists only fleetingly in nature. Yet scientists at Texas A&M University have found a way to harness its potential. Using cyclotron beams and advanced…

Tiny implant wipes out bladder cancer in 82% of patients

A new targeted drug delivery system called TAR-200 has shown remarkable results in a phase 2 clinical trial, eliminating tumors in 82% of patients with high-risk non-muscle-invasive bladder cancer that had resisted prior treatment. In most cases, the cancer disappeared within three months of therapy, and nearly half of the…

Entangled spins give diamonds a quantum advantage

The quest to create useful quantum technologies begins with a deep understanding of the strange laws that govern quantum behavior and how those principles can be applied to real materials. At the University of California, Santa Barbara, physicist Ania Jayich, Bruker Endowed Chair in Science and Engineering, Elings Chair in…

This 14th century story fooled the world about the Black Death

Researchers have traced long-standing myths about the rapid spread of the Black Death across Asia to a single source from the fourteenth century. For centuries, depictions of the plague racing along the Silk Route, devastating cities and towns in its path, have been based on a misunderstanding of a rhyming…

Brain-like learning found in bacterial nanopores

Pore-forming proteins are widespread across living organisms. In humans, they are essential for immune defense, while in bacteria they often act as toxins that puncture cell membranes. These microscopic pores allow ions and molecules to move through membranes, controlling molecular traffic within cells. Because of their precision and control, scientists…

Scientists turn body fat into bone to heal spinal fractures

Researchers at Osaka Metropolitan University have developed a promising new method to repair spinal fractures using stem cells extracted from adipose tissue, or body fat. In animal studies, the treatment successfully healed spinal injuries in rats that mimic osteoporosis-related fractures seen in humans. Because these cells are easy to collect,…

Scientists uncover a hidden universal law limiting life’s growth

A team of researchers, including a scientist from the Earth-Life Science Institute (ELSI) at the Institute of Science Tokyo in Japan, has identified a new principle in biology that mathematically explains why the growth of living organisms slows down when nutrients become plentiful. This well-known phenomenon is referred to as…

Running on little sleep? You’re twice as likely to get hurt

If you’re one of the 620 million people who regularly go for a run, you probably like to get an early start. But if you haven’t slept well the night before, you could be putting yourself at greater risk of injury. A new study led by Professor Jan de Jonge,…

Clearing brain plaques isn’t enough to heal Alzheimer’s

Researchers at Osaka Metropolitan University in Japan, led by graduate student Tatsushi Oura and Dr. Hiroyuki Tatekawa, discovered that the Alzheimer’s treatment lecanemab, which removes amyloid plaques from the brain, does not improve the brain’s waste clearance system in the short term. The results indicate that even after treatment, the…

AI revives lost 3,000-year-old Babylonian hymn

A long-lost hymn of praise dating back to around 1000 BCE has been identified through modern technology. Professor Enrique Jiménez of LMU uncovered the text and linked it to 30 additional manuscripts using artificial intelligence. Working in partnership with the University of Baghdad, Professor Jiménez rediscovered a Babylonian text that…

Astronomers just solved the mystery of “impossible” black holes

An extensive series of computer simulations led by astrophysicists at the Flatiron Institute and their collaborators has revealed that magnetic fields are the missing factor behind the creation of black holes whose masses fall within a range once thought impossible. In 2023, astronomers witnessed a dramatic event: two extraordinarily massive…

Goodbye cavities? This new toothpaste made from hair can heal enamel

A new approach to oral care may come from an unexpected source: your own hair.
