Study has revealed new insights into Stone Age life and death, showing that stone tools were just as likely to be buried with women and children as with men. The discovery, from Zvejnieki cemetery in northern Latvia, one of the largest Stone Age burial sites in Europe, challenges the idea that stone tools were strictly associated with men. The site was used for more than 5,000 years, and contains over 330 graves, but until now, stone artefacts found in burials had not been studied, with stone tools at Zvejnieki and ...

FOR IMMEDIATE RELEASE, September 10, 2025 Contact: Gina DiGravio, 617-358-7838, ginad@bu.edu Protein Found in the Eye and Blood Significantly Associated with Cognition Scores May serve as a biomarker for the detection of mild cognitive impairment, early dementia (Boston)—Neurocognitive impairments are classified by pathological changes with potential for destruction of neural tissue. One change known to occur in neurodegenerative disorders is an accumulation of proteins causing pathological damage.   While prior reports have suggested a link between Slit Guidance Ligand 2 (SLIT2) protein levels and late-onset ...

Key takeaways: Hormones matter for the voice: Falling estrogen and progesterone during menopause can cause hoarseness, vocal fatigue and instability, with major impact on singers, teachers, actors and other voice professionals. An overlooked women’s health issue: Many women with vocal changes are dismissed or misdiagnosed, underscoring the need for stronger collaboration between gynecologists and voice specialists. Promising new solutions: From AI-powered voice biomarkers to hormone therapy and vocal fold injections, innovative approaches are emerging to detect and treat menopause-related ...

Artificial intelligence is changing how we shop online, but when it comes to selling products through livestreams, humans still have the edge. A new study from the UBC Sauder School of Business shows that AI-powered “digital streamers”—virtual salespeople who appear in livestreams to promote products—don’t perform as well as human streamers. In fact, they barely outperform having no streamer at all. “People assume that if businesses are using digital streamers, they must be doing well. But they aren’t, at least not in their current incarnation,” said UBC Sauder associate professor Dr. Yanwen Wang, a co-author ...

A quicker, cheaper MRI scan was just as accurate at diagnosing prostate cancer as the current 30-40 minute scan and should be rolled out to make MRI scans more accessible to men who need one, according to clinical trial results led by UCL, UCLH and the University of Birmingham. The PRIME trial, funded by the John Black Charitable Foundation and Prostate Cancer UK, and published in JAMA, confirms that a two-part MRI scan is just as effective at diagnosing prostate cancer, whilst cutting scan time to just 15-20 ...

Strict embargo: not for publication or external distribution until 10 September 2025 at 16:00 (London time), 10 September 2025 at 11:00 (US Eastern Time)  For centuries, astronomers have puzzled over the origins of one of the universe’s oldest and densest stellar systems, known as globular clusters. Now, a University of Surrey-led study published in Nature has finally solved the mystery using detailed simulations – while also uncovering a new class of object that could already be in our own galaxy.   Globular ...

CAMBRIDGE, MA -- A new study from MIT neuroscientists reveals how rare variants of a gene called ABCA7 may contribute to the development of Alzheimer’s in some of the people who carry it. Dysfunctional versions of the ABCA7 gene, which are found in a very small proportion of the population, contribute strongly to Alzheimer’s risk. In the new study, the researchers discovered that these mutations can disrupt the metabolism of lipids that play an important role in cell membranes.  This disruption makes neurons hyperexcitable and ...

NEW YORK — It’s natural to crave sugar when you feel tired and want a boost of energy. Now scientists at Columbia University’s Zuckerman Institute have linked a brain area in mice to the drive to consume not just sweets, but fats, salt and food. The findings show this area serves as a kind of dial that can amplify or repress consumption.  This discovery, detailed today in Cell, may inform novel treatments for both overeating and undereating. For instance, the results suggest that finding ways to modulate this brain circuit may help treat people suffering from the severe loss of appetite and muscle wasting often seen in large numbers of chemotherapy patients. “The ...

New York, NY [September 10, 2025]—Lung tumors don’t just evade the immune system. They reshape it at its source. Researchers from the Icahn School of Medicine at Mount Sinai and collaborators report in the September 10 online issue of Nature [10.1038/s41586-025-09493-y] that tumors rewire immune cells in the bone marrow before they even reach the cancer, suggesting a new target to enhance the durability of current immunotherapy. Immunotherapies, which rally the body’s defenses against cancer, have transformed care for many ...

Most of the Earth’s fresh water is locked in the ice that covers Antarctica. As the ocean and atmosphere grow warmer, that ice is melting at a startling pace with sea levels and global currents changing in response. To understand the potential implications, researchers need to know just how fast the ice is disappearing, and what is driving it back. The West Antarctic ice sheet, an unstable expanse bordering the Amundsen Sea, is one of the greatest sources of uncertainty in climate projections. Records indicate that it has been steadily shrinking since the 1940s, but key details are missing. Using environmental data gathered from ice samples, tree rings and corals, ...

EMBARGOED UNTIL 8AM PACIFIC TIME/11AM EASTERN TIME, SEPTEMBER 10   On September 14, 2015, a signal arrived on Earth, carrying information about a pair of remote black holes that had spiraled together and merged. The signal had traveled about 1.3 billion years to reach us at the speed of light—but it was not made of light. It was a different kind of signal: a quivering of space-time called gravitational waves, first predicted by Albert Einstein 100 years prior. On that day 10 years ago, the twin detectors of the Laser Interferometer Gravitational-Wave Observatory ...

A new study co-authored by Texas A&M University geologist Dr. Michael Tice has revealed potential chemical signatures of ancient Martian microbial life in rocks examined by NASA’s Perseverance rover. The findings, published by a large international team of scientists, focus on a region of Jezero Crater known as the Bright Angel formation — a name chosen from locations in Grand Canyon National Park because of the light-colored Martian rocks. This area in Mars’ Neretva Vallis channel contains fine-grained mudstones rich in oxidized iron (rust), phosphorus, sulfur and ...

Vision happens when patterns of light entering the eye are converted into reliable patterns of brain activity. This reliability allows the brain to recognize the same object each time it is seen. Our brains, however, are not born with this ability; instead, we develop it through visual experience. Collaborating scientists at MPFI and the Frankfurt Institute for Advanced Studies have recently discovered key circuit changes that lead to the maturation of reliable brain activity patterns. Their findings, published in Neuron this week, are likely generalizable beyond vision, providing a ...

Researchers have uncovered a surprising role for electricity in keeping our body’s protective cell layers healthy. Cells bumping against one another use electricity to identify which of their neighbours has the least energy to kill them. The King’s College London study in partnership with the Francis Crick Institute provides insight into diseases including cancer and stroke, where cellular energy levels can be disrupted, preventing the maintenance of healthy cell numbers. Epithelial cells, which line all organs in the body, turnover rapidly to maintain a tightly packed protective layer. They undergo a process called ‘extrusion’ ...

WASHINGTON — Researchers have developed a motion-compensation method that allows single-pixel imaging to capture sharp images of complex dynamic scenes. The new approach could expand the practical utility of this computational imaging method by enabling clearer images of moving targets and improving the quality of surveillance images. Single-pixel imaging uses a single detector, rather than the traditional array of pixels, to acquire images. Although it offers several advantages, such as high sensitivity ...

As attention turns to this year’s New York City Marathon, observers will again ask a long-standing question: What do athletes draw upon when trying to complete this 26.2-mile run, especially at those stretches when finishing seems impossible?  Many might think that when fatigue sets in, the key to perseverance is reminding oneself why the effort is worth it or focusing on reasons why they set the goal—intuition that lines up with motivational posters, sports psychology clichés, and coaching advice. ...

URBANA, Ill. — Scientists from the University of Illinois Urbana-Champaign have developed a method to isolate genes from amounts of microbial DNA so tiny that it would take 20,000 samples to weigh as much as a single grain of sugar. In a new paper, the researchers discovered previously unknown antibiotic resistance genes in bacterial DNA isolated from human stool and from fish tanks at Chicago’s Shedd Aquarium. “With antibiotic resistance on the rise, it’s more important than ever to understand the full diversity of mechanisms bacteria may ...

PLYMOUTH MEETING, PA [September 10, 2025] — New research published in the September 2025 issue of JNCCN—Journal of the National Comprehensive Cancer Network validates the use of a specifically-curated tool for determining which medications may be causing harm for older patients with cancer. Researchers affiliated with the Veterans Affairs (VA) Healthcare System in Boston evaluated a tool based on information from the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for Older Adult Oncology, called the “Geriatric ...

Washington, September 10, 2025—State school finance reforms designed to close funding gaps between high- and low-income districts did not reduce racial and ethnic funding inequities and in some cases increased them, according to new research. As school desegregation efforts slowed in the decades following the 1980s, these findings highlight the limitations of income-based approaches in addressing racial funding disparities in education. The study, by Emily Rauscher of Brown University and Jeremy E. Fiel of Rice ...

Endometrial cancer is a major gynecologic malignancy, with HGEC comprising aggressive variants such as Grade 3 endometrioid, serous, clear cell, undifferentiated/dedifferentiated carcinomas, carcinosarcoma, and mesonephric-like adenocarcinoma. These tumors are characterized by poor prognosis and resistance to conventional therapies. The limitations of traditional histopathological diagnosis underscore the need for molecular refinement to guide clinical management. Histopathological Subtypes of HGEC FIGO Grade 3 Endometrioid Carcinoma (HG-EEC): Characterized ...

AMHERST, Mass. — Physicists have long believed that black holes explode at the end of their lives, and that such explosions happen—at most—only once every 100,000 years. But new research published in Physical Review Letters by physicists at the University of Massachusetts Amherst has found a more than 90% probability that one of these black-hole explosions might be seen within the decade, and that, if we are prepared, our current fleet of space and earthbound telescopes could witness the event. Such an explosion would be strong evidence of a theorized but never observed kind of black hole, called a “primordial black hole,” ...
