Models that inform how magma moves and volcanic eruptions unfold may need an update, according to a new study. It reports that gas bubbles in magmas can form through the mechanical forces of shear as magmas flow and deform–  a new physical mechanism for magma bubble nucleation that challenges conventional degassing models. The formation of gas bubbles within magma – also known as nucleation – is a fundamental process that shapes how volcanic eruptions unfold. The timing and rate at which these bubbles appear and expand influences key magma features, including its buoyancy, viscosity, and explosive potential. Understanding nucleation is therefore vital for ...

Arctic sea ice has declined by more than 42% since 1979, when regular satellite monitoring began. As the ice grows thinner and recedes, more water is exposed to sunlight. Ice reflects sunlight but dark water absorbs it, advancing warming and accelerating ice loss. Climate models indicate that the Arctic will see ice-free summers within the coming decades, and scientists still aren’t sure what this will mean for life on Earth.  Researchers have known for some time that fine-grained dust from space blankets the surface of Earth, falling from the cosmos at a constant rate and settling into ocean sediments. A study published Nov. 6 in Science shows that tracking where cosmic dust has ...

Superconductors are like the express trains in a metro system. Any electricity that “boards” a superconducting material can zip through it without stopping and losing energy along the way. As such, superconductors are extremely energy efficient, and are used today to power a variety of applications, from MRI machines to particle accelerators.  But these “conventional” superconductors are somewhat limited in terms of uses because they must be brought down to ultra-low temperatures using elaborate cooling systems to keep them in their superconducting state. If ...

For decades, scientists have generally thought that rivers emit more carbon dioxide, a greenhouse gas, than they take in. But a new analysis of every river network in the contiguous United States — including underrepresented rivers in deserts and shrublands — challenges this assumption, uncovering hints that many Western waterways may be soaking up carbon dioxide from the atmosphere. The findings were published in Science and led by Taylor Maavara, an aquatic biogeochemist at Cary Institute of Ecosystem Studies. “Rivers ...

(Vienna, 6 November 2025) Inside every cell, a finely tuned metabolic network determines when to build, recycle, or stop producing essential molecules. A central part of this network is folate metabolism, a process that provides vital chemical units for the synthesis of DNA, RNA, and amino acids. When this system is disturbed - for example through genetic mutations or a lack of dietary folates - the consequences can range from developmental disorders to cancer. Now, researchers from CeMM, the Research ...

New research has used purchasing data to map areas of London where residents may be suffering from a nutritionally inadequate diet, pinpointing where there are ‘food deserts.’ Researchers from the University of Nottingham and Adelaide analysed Tesco food purchasing records from 1.6 million people across London to understand how food purchase patterns vary and what they reveal about health. Their results, published today in PLOS Complex Systems, show clear differences in the nutritional ...

New research has confirmed that West Coast transient killer whales who live between British Columbia and California are two distinct subpopulations: inner and outer coast transients. Based on 16 years of data from more than 2,200 encounters, the study published in PLOS One challenges previous assumptions about this group of mammal-eating killer whales. “I've been thinking about this possibility for 15 years,” says first author Josh McInnes, who conducted the research as part of his masters at UBC’s Institute for the Oceans and Fisheries (IOF). “Now our findings show the West Coast ...

Lasers that emit extremely short light pulses are highly precise and are used in manufacturing, medical applications, and research. The problem: efficient short-pulse lasers require a lot of space and are expensive. Researchers at the University of Stuttgart have developed a new system in cooperation with Stuttgart Instruments GmbH. It is more than twice as efficient as previous systems, fits in the palm of a hand, and is highly versatile. The scientists describe their approach in the journal Nature. (DOI: 10.1038/s41586-025-09665-w) Eighty percent efficiency is possible “With our new system, we can achieve levels of efficiency ...

A widely prescribed diabetes drug may be sabotaging one of the most trusted strategies for preventing the disease: exercise. That is the conclusion of a Rutgers-led study published in The Journal of Clinical Endocrinology & Metabolism, which found that metformin blunts critical improvements in blood vessel function, fitness and blood sugar control that normally come from working out. Since 2006, doctors have been advised to tell patients with high blood sugar to take metformin while engaging in exercise. Two proven therapies should deliver better results together, they reasoned. But Rutgers researchers ...

Tambet Teesalu, University of Tartu Professor of Nanomedicine, has been awarded an ERC Synergy Grant to study the blood-nerve barrier – the interface between blood vessels and nerve cells – in search of solutions to shortcomings in pain treatment.  Teesalu’s research group, in collaboration with colleagues from the United Kingdom, Italy and France, will focus closely on the peripheral nervous system to create a detailed molecular and spatial map of the blood-nerve barrier and therapeutic approaches that could influence ...

A new dataset released via the Human Climate Horizons (HCH) data platform by the United Nations Development Programme (UNDP) Human Development Report Office, in collaboration with the Climate Impact Lab, warns that climate change is set to dramatically undermine agricultural productivity, with some of the greatest risks concentrated in countries least able to adapt. The dataset, sourced from a Nature study released in June by the Climate Impact Lab and collaborating institutions [press release], finds every additional degree Celsius of global warming ...

Quantum computers are powerful, lightning-fast and notoriously difficult to connect to one another over long distances.  Previously, the maximum distance two quantum computers could connect through a fiber cable was a few kilometers. This means that, even if fiber cable were run between them, quantum computers in the University of Chicago’s South Side campus and downtown Chicago’s Willis Tower would be too far apart to communicate with each other.  Research published today in Nature ...

NEW ORLEANS (Nov. 6, 2025) —Fewer than half of young adults with severely high low-density lipoprotein (LDL-C), or “bad” cholesterol, levels start taking a statin within five years of first high LDL-C measurement, according to a study published in JACC, the flagship journal of the American College of Cardiology, and presented at the American Heart Association’s 2025 Scientific Sessions. The 2018 ACC/AHA Cholesterol Guideline recommends a statin in patients with LDL-C over 190 mg/dL and these ...

HERSHEY, Pa. — In June 2022, the U.S. Supreme Court’s decision in Dobbs v. Jackson Women’s Health Organization ended the federal constitutional right to abortion and returned authority to individual states to regulate abortion. A new study from researchers at Penn State, Albany Medical Center, University of South Florida and University of Tennessee Medical Center revealed that the change in abortion policies appears to have a trickle-down effect, influencing reproductive health and family planning decisions. The research team found that the number of women undergoing tubal ligations — ...

Current U.S. immigration enforcement and deportation policies are producing widespread harm to physical and mental health, with family separation and the specters of fear and intimidation affecting the well-being of immigrant and non-immigrant communities. That’s the warning from several longtime public health researchers, who also outline proven community and policy actions that could reduce harm and strengthen health in communities across the nation. Professors from five prestigious U.S. research universities called for health care professionals and researchers to advocate for the end of deportations and restrictive immigration policies. Their insights appear in the ...

Toronto, ON, November 6, 2025 – Adults diagnosed with a concussion may be at about 50 per cent higher risk of a subsequent traffic crash, finds a new study from researchers at ICES and Sunnybrook Research Institute. Concussions can temporarily affect brain function, with symptoms including insomnia, dizziness, depression, brain fog, and slowed reaction times that can linger for weeks. These symptoms could alter driving skills and increase the risk of a motor vehicle accident. “I worry ...

When Linda Moslow, A16P, A18P, entered perimenopause in her early 40s, she was blindsided. “I’d always been healthy and grounded in wellness,” she says. “Suddenly, I couldn’t recognize myself.” The months of anxiety, sleeplessness, and confusion that followed left her feeling unmoored until she found a team of doctors who helped her understand what was happening. The experience was both personal and galvanizing. Realizing that millions of women lacked the support she’d been lucky to find, Moslow started ...

Plant biologists have developed a method for growing transgenic and gene-edited plants that cuts the slow and expensive process down from months to weeks. Publishing November 6 in the Cell Press journal Molecular Plant, the method takes advantage of plants’ natural ability to regenerate after being wounded or pruned. By injecting bacteria carrying genetic instructions for wound healing and regeneration into a pruned plant’s wound site, the researchers triggered the plant to grow new shoots, some of which were transgenic and gene edited. The method shows potential even in species that ...

Type 1 diabetes is caused by an insufficient production of the hormone insulin by cells in the pancreas called beta cells and estimated to affect 9.5 million people worldwide. Low insulin levels allow glucose levels to remain elevated, which in the long term can damage organs such as the kidneys, the eyes, and the cardiovascular system. People with diabetes require lifelong monitoring of blood sugar levels coupled with insulin injections to keep blood sugar levels at a stable, healthy level. A potential new treatment option ...

A new high resolution digital dataset and map — named Itiner-e — of roads throughout the Roman Empire around the year 150 CE is presented in research published in Scientific Data. The findings increase the known length of the Empire’s road system by over 100,000 kilometres. At its height in the second century CE, the Roman Empire included over 55 million people and stretched from modern day Britain to Egypt and Syria. Although a network of roads throughout the Empire facilitated ...

About The Study: In this large, diverse sample of first-time mothers in the U.S., 1 in 27 participants reported feeding their infants shared human milk. Prior work indicates that families engage in many, but not all, recommended milk sharing risk mitigation measures and fear disclosing their milk sharing to practitioners. Given the prevalence in this study, pediatric practitioners should be aware that milk sharing occurs across demographics; they can counsel families considering or using shared milk on risks and risk-reduction strategies ...

Over-the-counter pain medications work as well or better than opioids after wisdom tooth extraction for both men and women, according to a Rutgers Health-led follow-up to a landmark paper on comparative pain relief. That first paper on the collective experience of more than 1,800 trial patients found that the combination of ibuprofen and acetaminophen provided better pain relief than hydrocodone with acetaminophen for the first two days after surgery and greater satisfaction over the post-operative period. The new subgroup analysis, published in JAMA Network Open, demonstrated that the results held for both ...
