Many marine species are no strangers to the depths of the oceans. Some animals, like certain sharks, tuna, or turtles, routinely perform extreme dives, whereas for other species such behavior has been observed less frequently. Now, an international team of researchers working in Peru, Indonesia, and New Zealand tagged oceanic manta rays – the largest species of ray – to learn more about the deep-diving behavior of these animals. They published their results in Frontiers in Marine Science. “We show that, ...

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by international pulsar timing array collaborations in 2023 could come from a stochastic gravitational-wave background—the sum of many distant sources—or from a single nearby binary of supermassive black holes. To tell these apart, Hideki Asada, theoretical physicist and Professor at Hirosaki University, and Shun Yamamoto, researcher at the Graduate School of Science and Technology, Hirosaki University, propose a method that exploits beat phenomena between gravitational waves at nearly the same frequency, searching for ...

Through controlled experiments and theoretical calculations, they explored the reaction mechanism, including the cleavage of both the π and σ bonds of the olefins, ...

POSTECH (Pohang University of Science and Technology) Professor Hyung Joo Lee’s research team, including integrated program students Min Young Shin and Na Rae Kim, has published the results of a study analyzing how the combined effects of droughts and wildfires influence fine particulate matter (PM2.5) in California, U.S., using 15 years of data. The study was published in the international environmental science journal Environment International.   PM2.5 refers to fine particles with an aerodynamic diameter of 2.5 micrometers (µm) or less. Because these particles can penetrate deep into the lungs when inhaled, causing respiratory ...

Uncontrolled bleeding during surgery remains one of the deadliest medical emergencies. Injuries to internal organs such as the liver or spleen are especially dangerous because bleeding is difficult to control and often life-threatening. To tackle this challenge, researchers at POSTECH (Pohang University of Science and Technology) have developed a composite bioabsorbable hemostatic sponge that can rapidly halt bleeding inside the body.   Conventional hemostatic agents often fail to adhere firmly to the bleeding site or remain in the body without degrading, which can cause secondary complications. To address this, the research team ...

Poorer health is linked to a higher proportion of votes for the populist right wing political party, Reform UK, indicates an analysis of the 2024 general election voting patterns in England, published online in the open access journal BMJ Open Respiratory Research. The findings should prompt policy-makers of all political stripes to step up efforts to improve public health and tackle health inequalities, suggest the researchers. Reform UK secured 14% of votes in last year’s UK general election, winning five of the English constituency seats available. And in May this year, it won a substantial number of council seats in local authority elections ...

Loneliness and social isolation are linked to a heightened risk of death from cancer as well as from all causes among those with the disease, finds a pooled data analysis of the available research published online in the open access journal BMJ Oncology. Globally, new cases of cancer are projected to rise to 35 million, and associated deaths to 18.5 million by 2050, note the researchers.  Loneliness is relatively common among people with cancer, and while loneliness is associated with various health issues, including cognitive ...

Sports footwear manufacturers need to ditch the ‘shrink it and pink it’ approach to women’s running shoes, because this is failing to differentiate their distinct anatomical and biomechanical needs across the life course from those of men, concludes a small qualitative study published in the open access journal BMJ Open Sports & Exercise Medicine. Female-, rather than male-based, designs might not only boost women runners’ comfort, but also enhance injury prevention, and their performance, say the researchers. Over the past 50 years, manufacturers have invested billions of dollars on developing running shoes that can prevent injury, maximise comfort, ...

Study outlines tactical playbook deployed by male abusers to “weaponise love” based on in-depth interviews with victims.   Current therapeutic approaches should move away from “victim pathology” and focus on “perpetrator strategy”, argues researcher. Before going on to commit violence, domestic abusers use a mix of intense affection and emotional cruelty, combined with tales of their own childhood trauma, to generate a deep psychological hold that can feel like an “addiction” according to some victims.  A new study by a University of Cambridge criminologist ...

Rapid and urgent action on food is needed if the UK is to reboot its flagging economy, save the NHS billions, ensure national food security, and meet climate commitments, according to a new report. The Roadmap for Resilience: A UK Food Plan for 2050, calls for radical transformation, at a scale and pace not seen since the Second World War. It says if we do not act now, change will be forced upon us by increasing pressures and the UK will lurch from crisis to crisis, including from food price shocks, climate disasters and weakening economic productivity. Acting now however, allows the UK to decide its own future, and must include ...

HOUSTON – (Oct. 14, 2025) – When doctors analyze a medical scan of an organ or area in the body, each part of the image has to be assigned an anatomical label. If the brain is under scrutiny for instance, its different parts have to be labeled as such, pixel by pixel: cerebral cortex, brain stem, cerebellum, etc. The process, called medical image segmentation, guides diagnosis, surgery planning and research. In the days before artificial intelligence (AI) and machine learning (ML), clinicians performed this crucial yet painstaking and time-consuming task by hand, but over the past decade, U-nets ⎯ a type of ...

A new study in Biochar reveals that nitrogen-fortified nanobiochar could significantly improve soil fertility and rice yields while reducing dependence on synthetic fertilizers.

Nanobiochar, biochar particles engineered at the nanoscale, has attracted attention for its porous ...

ITHACA, N.Y. –  Art infusion theory – the idea that displaying art in retail settings can positively impact consumer behavior – can be applied to the metaverse with similar results, a Cornell design researcher has shown. Employing algorithm-fueled generative art, So-Yeon Yoon, professor of human centered design at Cornell University, found that the installation in a virtual store enhanced perceptions of exclusivity and aesthetic pleasure for both mass-market and luxury retailers. “When we think about art, we think it’s more closely aligned with the luxury market,” ...

Darwin Quiroz is exploring new frontiers in miniature lasers with major biomedical applications. When Quiroz first started working with optics as an undergraduate, he was developing atomic magnetometers. That experience sparked a growing curiosity about how light interacts with matter, an interest that has now led him to a new technique in optical imaging. Quiroz, a PhD student in the Department of Electrical, Computer and Energy Engineering at the University of Colorado Boulder, is co-first author of a new study that demonstrates how a fluid-based optical device known as an electrowetting prism can be used to steer lasers at high speeds for advanced imaging applications.  The ...

Trees are essential to cooling down cities. However, a study by Concordia researchers at the Next Generation Cities Institute and the Loyola Sustainability Research Centre shows how tree distribution influences how some residents benefit more from them than others. In a paper published Urban Forestry & Urban Greening, the authors studied the layout of Montreal’s vegetation — its trees, shrubs and grass — and compared it to daytime temperature readings on the ground, or land surface. Using ...

Ribosomal RNA (rRNA) is a type of molecule and a key building block of the ribosome, the cell’s protein-making machinery. rRNA accounts for much of the RNA in a cell, and it’s crucial for life. “It’s essentially one of the most important molecules that we have,” says Thomas Jefferson University researcher Isidore Rigoutsos, PhD. “But for nearly seven decades, we thought rRNA was only relevant to the ribosome.” Now, a new study from Dr. Rigoutsos’ lab ...

A new study has uncovered how tiny differences in boron atoms can help scientists better predict the long-term behavior of glass used to store hazardous waste. The findings, published in Environmental and Biogeochemical Processes, could improve forecasts of how radioactive materials are released from storage over thousands of years. Glass is often used to immobilize contaminants such as radionuclides and heavy metals, locking them safely inside a stable structure. However, when groundwater seeps into disposal sites, the glass can gradually dissolve. Understanding this process is crucial for ensuring the safety of geological ...

Mediterranean vineyards face a growing threat from heavy rains and soil degradation that strip away fertile topsoil. New research led by scientists at the University of Aveiro, Portugal, shows that adding biochar, a carbon-rich material made from plant waste, can dramatically reduce erosion and improve the soil’s ability to store water. The study, published in Biochar, is among the first to test biochar’s impact on the “soil sponge function” under natural rainfall in sloping Mediterranean vineyards. Over 18 months, researchers used outdoor lysimeters filled with vineyard ...

Manufacturing better batteries, faster electronics, and more effective pharmaceuticals depends on the discovery of new materials and the verification of their quality. Artificial intelligence is helping with the former, with tools that comb through catalogs of materials to quickly tag promising candidates.  But once a material is made, verifying its quality still involves scanning it with specialized instruments to validate its performance — an expensive and time-consuming step that can hold up the development and distribution of new technologies.  Now, a new AI tool developed by MIT ...

Catonsville, MD, Oct. 10, 2025 — A new study has tested whether hiding authors’ identities in the peer review process makes academic evaluations more fair, reliable and valid. The answer: it’s complicated. The research was published in the INFORMS journal Management Science in an article entitled, “Blinded versus Unblinded Review: A Field Study on the Equity of Peer-Review Processes.” The study was conducted by Timothy Pleskac of Indiana University; Ellie Kyung of Babson College; Gretchen Chapman of Carnegie Mellon University; and Oleg Urminsky of the University ...

A tiny worm that leaps high into the air — up to 25 times its body length — to attach to flying insects uses static electricity to perform this astounding feat, scientists have found. The journal PNAS published the work on the nematode Steinernema carpocapsae, a parasitic roundworm, led by researchers at Emory University and the University of California, Berkeley. “We’ve identified the electrostatic mechanism this worm uses to hit its target, and we’ve shown the importance of this mechanism for the worm’s survival,” says co-author Justin Burton, an Emory professor of physics whose lab led the mathematical analyses of laboratory experiments. “Higher ...
