People with pockets of fat hidden inside their muscles are at a higher risk of dying or being hospitalised from a heart attack or heart failure, regardless of their body mass index, according to research published in the European Heart Journal [1] today (Monday).   This ‘intermuscular’ fat is highly prized in beef steaks for cooking. However, little is known about this type of body fat in humans, and its impact on health. This is the first study to comprehensively investigate the effects of fatty muscles on heart disease.   The new finding adds evidence that existing measures, such as body mass index or waist ...

Ecologists from the School of Biological Sciences (SBS) and the Swire Institute of Marine Science (SWIMS) at The University of Hong Kong (HKU) have identified significant ecological risks associated with the release of hybrid groupers into Hong Kong’s coastal waters, a practice often linked to religious ‘mercy release’ rituals. Their study highlights how the Tiger Grouper-Giant Grouper hybrid (TGGG), also known as the Sabah grouper, disrupts local marine ecosystems by exploiting unique ecological niches and potentially becoming a dominant predator. This research, the first ...

The National Champion Tree Program (NCTP) announced its first Register of Champion Trees since 2021. The program moved from American Forests to the University of Tennessee School of Natural Resources in 2023 and has spent the past year working with state-level Champion Tree programs across the U.S. to update outdated records and verify the newly crowned champions. “We are thrilled beyond measure to share the list of the largest documented trees in the United States,” Jaq Payne, NCTP director, said. “These trees are more than just numbers on a website. They're living, breathing members of our community. I hope this register encourages folks to start ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have discovered a new superconducting material. They combined iron, nickel, and zirconium, to create a new transition metal zirconide with different ratios of iron to nickel. While both iron zirconide and nickel zirconide are not superconducting, the newly prepared mixtures are, exhibiting a “dome-shaped” phase diagram typical of so-called “unconventional superconductors,” a promising avenue for developing high temperature superconducting materials which can be more widely deployed in society.   Superconductors already play ...

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality globally, posing a particularly significant threat to people with HIV (PWH). To address this, CVD prevention plans rely on prediction models like atherosclerotic cardiovascular disease (ASCVD) risk scores to estimate the risk of heart disease. However, previous studies have called into question whether these commonly used prediction models perform well among people with HIV, and there remains a gap in understanding of what these scores mean for PWH in low- and middle-income countries (LMICs). Researchers from Massachusetts General Hospital, a founding member of the Mass General Brigham ...

Cultural traits — the information, beliefs, behaviors, customs, and practices that shape the character of a population — are influenced by conformity, the tendency to align with others, or anti-conformity, the choice to deliberately diverge. A new way to model this dynamic interplay could ultimately help explain societal phenomena like political polarization, cultural trends, and the spread of misinformation.  A study published in the Proceedings of the National Academy of Sciences outlines this novel approach. Presenting a mathematical model, SFI Complexity Postdoctoral Fellow Kaleda Denton with colleagues ...

A research team from NIMS and the Japan Fine Ceramics Center (JFCC) has developed a next-generation AI device—a hardware component for AI systems—that incorporates an iono-magnonic reservoir. This reservoir controls spin waves (collective excitations of electron spins in magnetic materials), ion dynamics and their interactions. The technology demonstrated significantly higher information processing performance than conventional physical reservoir computing devices, underscoring its potential to transform AI technologies. As AI devices become increasingly sophisticated, ...

By Shawn Ballard The complexity of the human brain – 86 billion neurons strong with more than 100 trillion connections – enables abstract thinking, language acquisition, advanced reasoning and problem-solving, and the capacity for creativity and social interaction. Understanding how differences in brain signaling and dynamics produce unique cognition and behavior in individuals has long been a goal of neuroscience research, yet many phenomena remain unexplained. A study from neuroscientists and ...

As the atmosphere continues to fill with greenhouse gases from human activities, many proposals have surfaced to “geoengineer” climate-saving solutions, that is, alter the atmosphere at a global scale to either reduce the concentrations of carbon or mute its warming effect. One recent proposal seeks to infuse the atmosphere with hydrogen peroxide, insisting that it would both oxidize methane (CH4), an extremely potent greenhouse gas while improving air quality. Too good to be true? University of Utah atmospheric scientists Alfred Mayhew and Jessica Haskins were skeptical, so they set out to test the claims behind this proposal. Their results, published on ...

ARLINGTON, Va.—A favorite childhood memory for Dr. Sandra Chapman was visiting the USS Arizona Memorial in Pearl Harbor with her father. They hung out at the memorial so often that they memorized lines to the movie playing prior to the boat ride to the memorial. So it’s appropriate that Chapman — a program officer in the Office of Naval Research’s (ONR) Warfighter Performance Department — is passionate about her involvement in the development of an innovative technology recently applied to efforts to preserve the area around the USS Arizona ...

Images EAST LANSING, Mich. – Our sun is essentially a searing hot sphere of gas. Its mix of primarily hydrogen and helium can reach temperatures between 10,000 and 3.6 million degrees Fahrenheit on its surface and its atmosphere’s outermost layer. Because of that heat, the blazing orb constantly oozes a stream of plasma, made up of charged subatomic particles — mainly protons and electrons. The sun’s gravity can’t contain them because they hold so much energy as heat, so they drift away into space as solar wind. Understanding how charged particles ...

As Donald Trump prepares to take office for a second term as President, research led by the University of California, Santa Cruz is demonstrating the important role nonprofits played during Trump’s first term as a counterforce that channeled public resistance to anti-immigrant policies. The new study, published in the journal International Migration Review, shows how nonprofits that provide legal services for immigrants ended up receiving increases in public contributions in the wake of Trump's attacks on immigrants.  Previously, there had been many reported examples of this backlash effect, sometimes called ...

Like many rare diseases, fibrolamellar hepatocellular carcinoma (FLC) mounts a ferocious attack against an unlucky few—in this case, children, adolescents, and young adults. Because its symptoms can vary from person to person, it’s often missed or misdiagnosed until it has metastasized and becomes lethal. Moreover, drug therapies for common liver cancers are not just useless for FLC patients but actually harmful. But new insights about the disease, coupled with a just-launched clinical trial of a promising drug treatment, could significantly improve health outcomes. Researchers in Rockefeller University’s Laboratory of Cellular Biophysics, headed by Sanford ...

Researchers at the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) have developed a new sorghum variant that can outperform soybeans in oil production, with great potential as a clean source of renewable fuel. Scientists have long worked to create new sustainable sources of vegetable oils, known as triacylglycerols (TAG), to meet the growing demand for renewable fuels like sustainable aviation fuel (SAF) and renewable diesel. Currently, oil palm and oilseeds such as soybeans provide most TAG for renewable ...

SAN FRANCISCO—Every 40 seconds, someone in the United States has a stroke. For survivors of the most common type of stroke, called an ischemic stroke, only about 5 percent fully recover. Most others suffer from long-term problems, including weakness, chronic pain, or epilepsy. Now, scientists at Gladstone Institutes and the regenerative medicine company SanBio have shown that a cell therapy derived from stem cells can restore normal patterns of brain activity after a stroke. While most stroke treatments must be administered in the immediate hours ...

Polymer editing can upcycle waste into higher-performance plastics   By editing the polymers of discarded plastics, chemists at the Department of Energy’s Oak Ridge National Laboratory have found a way to generate new macromolecules with more valuable properties than those of the starting material. Upcycling may help remedy the roughly 450 million tons of plastic discarded worldwide annually, of which only 9% gets recycled; the rest is incinerated or winds up in landfills, oceans or elsewhere.   ORNL’s ...

Tropical storms like hurricanes are not only terrifying, but also incredibly costly for coastal regions across the United States, Mexico, Central America and the Caribbean. Beyond the immediate devastation, these storms contribute to significant economic losses and human displacement. In 2023 alone, climate migration linked to such events saw 2.5 million individuals attempt to cross the U.S. southern land border. New research led by The University of Texas at Arlington emphasizes that studying ...

In the decades following the launch of NASA's Hubble Space Telescope, astronomers have tallied over 1 trillion galaxies in the universe. But only one galaxy stands out as the most important nearby stellar island to our Milky Way — the Andromeda Galaxy. It can be seen with the naked eye on clear autumn nights as a faint oval object roughly the size of the moon. A century ago, astronomer Edwin Hubble first established that this so-called "spiral nebula" was approximately 2.5 million light years away from our own Milky Way galaxy. Now, the space telescope named ...

LA JOLLA, CA—Many vaccines work by introducing a protein to the body that resembles part of a virus. Ideally, the immune system will produce long-lasting antibodies recognizing that specific virus, thereby providing protection. But Scripps Research scientists have now discovered that for some HIV vaccines, something else happens: after a few immunizations the immune system begins to produce antibodies against immune complexes already bound to the viral protein alone. They don’t yet know whether this chain reaction, described in Science ...

Scientists at Caltech and Princeton University have discovered that bacterial cells growing in a solution of polymers, such as mucus, form long cables that buckle and twist on each other, building a kind of "living Jell-O."   The finding could be particularly important to the study and treatment of diseases such as cystic fibrosis, in which the mucus that lines the lungs becomes more concentrated, often causing bacterial infections that take hold in that mucus to become life threatening. This discovery ...
