Key takeaways: By analyzing rare nitrogen isotopes in 5-million-year-old plankton fossils, researchers reconstructed past Pacific Ocean conditions to better forecast the future. Even during the warmer Pliocene Epoch, nutrient-rich upwelling in the tropical Pacific remained stable, sustaining marine productivity. The findings challenge predictions of a fisheries collapse. TAMPA, Fla. (Oct. 1, 2025) – A team of scientists has uncovered a rare isotope in microscopic fossils, offering fresh evidence that ocean ...

CAMBIRDGE, MA -- At the heart of all lithium-ion batteries is a simple reaction: Lithium ions dissolved in an electrolyte solution “intercalate” or insert themselves into a solid electrode during battery discharge. When they de-intercalate and return to the electrolyte, the battery charges. This process happens thousands of times throughout the life of a battery. The amount of power that the battery can generate, and how quickly it can charge, depend on how fast this reaction happens. However, little is known about the exact mechanism of this reaction, or ...

Polytetrafluoroethylene (PTFE) is a synthetic fluorine-based polymer with a wide range of applications, including non-stick cookware production and electrical and optical fiber cable coating, owing to its high durability, thermal stability, and low friction. Ironically, its durability also presents an environmental challenge for its disposal. PTFE is mainly disposed of via incineration, landfilling, and defluorination. However, incineration requires high energy and involves the release of hydrogen fluoride, which is highly corrosive. Meanwhile, landfilling leads to an environmental burden of undegraded PTFE. By contrast, defluorination, in ...

Bioengineers at the University of California San Diego have developed a powerful new technology that can map the entire network of RNA-protein interactions inside human cells — an achievement that could offer new strategies for treating diseases ranging from cancer to Alzheimer’s. RNA-protein interactions regulate many essential processes in cells, from turning genes on and off to responding to stress. But until now, scientists could only capture small subsets of these interactions, leaving much of the cellular “conversation” hidden. “This technology is like a wiring map of the cell’s conversations,” said ...

Adolescence is a period of social reorientation: a shift from a world centered on parents and family to one shaped by peers, schools, and broader networks. This expansion is critical for healthy development, but it also heightens susceptibility to social stressors. When those stressors lead young people to withdraw — choosing solitude more often than connection — the brain itself may be altered. Using brain imaging and behavioral data, Caterina Stamoulis, PhD, and her team in the Division of Adolescent/Young Adult Medicine at Boston Children’s Hospital have found that adolescents who are ...

When University of Texas at Arlington researcher Paul J. Fadel and his colleagues launched a study on vascular health in people with chronic kidney disease, they expected to better understand a long-standing belief. For years, scientists have pointed to a blood marker called ADMA—asymmetric dimethylarginine—as a warning sign for vascular problems. But the team’s findings, recently published in the American Journal of Physiology-Renal Physiology, told a different story. Instead, another blood marker, SDMA—symmetric dimethylarginine—long considered mostly inactive, showed a stronger connection to vascular health than ADMA. “The ...

Since 2022, American companies, consumers, and even the United Nations have used large language models—artificial intelligence (AI) systems such as ChatGPT that are trained to create text that reads like human-generated writing. In a study publishing October 2 in the Cell Press journal Patterns, researchers reveal that AI is used in an average of 17% of analyzed corporate and governmental written content, from job posts to press releases, and this rate will likely continue to increase.   “This is the first comprehensive review of the use of AI-assisted ...

The ‘big bad wolf’ fears the human ‘super predator’ – for good reason Fear of the fabled ‘big bad wolf’ has dominated the public perception of wolves for millennia and strongly influences current debates concerning human-wildlife conflict. Humans both fear wolves and, perhaps more importantly, are concerned about wolves losing their fear of humans – because if they fear us, they avoid us and that offers protection. A new Western University study shows that even where laws are in place to protect them, wolves fully fear the human ‘super predator.’ These findings ...

Chronic kidney disease (CKD) affects more than 700 million people worldwide and is caused by genetic and environmental factors, as well as existing medical conditions. Known genetic risk factors for CKD include mutations in a gene called APOL1.  These are rare in most populations, but two risk variants are present in as much as 13 percent of people with West African origin and another 38% possess one copy (carriers). The causes for APOL1-mediated kidney disease (AMKD) are currently not well ...

About The Study: This multicenter quality improvement study found that use of an ambient artificial intelligence (AI) scribe platform was associated with a significant reduction in burnout, cognitive task load, and time spent documenting, as well as the perception that it could improve patient access to care and increase attention on patient concerns in an ambulatory environment. These findings suggest that AI may help reduce administrative burdens for clinicians and allow more time for meaningful work and ...

A new study by the University of California, Davis, shows how cells work together to avoid a sudden drop in blood sugar. Understanding these feedback loops could improve the lives of people with diabetes and help them avoid dangerous hypoglycemia. The work was published Sept. 16 in Proceedings of the National Academy of Sciences.  People with diabetes must contend with the long-term risks of high blood sugar, such as blindness, kidney failure, and loss of circulation in the legs, which can ...

In a paper published in Nature Communications, researchers at Vanderbilt University Medical Center’s Department of Otolaryngology-Head and Neck Surgery leveraged two main studies — one focused on behavior and one focused on genetics — to highlight the correlation between participants’ musical rhythm abilities and developmental speech-language disorders.  These disorders include developmental language disorder, dyslexia and stuttering, among others.  Evidence showed that deficiency in musical rhythm perception is a “modest ...

PULLMAN, Washington -- More than half of survivors of the Sudan Ebola virus still suffer serious health problems two years post-infection and the virus can persist in semen and breast milk for months after recovery, according to the first study examining the virus’s long-term effects. The study, led by researchers at Washington State University, found 57.5% of the survivors of an outbreak in Uganda from 2022-23 reported ongoing and debilitating health issues that interfered with their daily lives. The detection of traces of the virus in semen and breast milk also raised concerns ...

Branching isn’t just for trees. This biological process occurs in animal development, enabling organs to perform complex functions. Branch-like structures form in lungs, kidneys, and breasts, among other places. Importantly, only in female mammary glands does most branching occur years after birth. It happens during puberty and again during pregnancy as milk ducts branch out in preparation for breastfeeding. Disturbances here have been linked to breast cancer. However, studying branching can be difficult and time-consuming. Now, Cold Spring Harbor Laboratory (CSHL) researchers have developed a tool to quickly quantify changes in the branches of mouse mammary glands. ...

Astronomers have identified an enormous ‘growth spurt’ in a so-called rogue planet. Unlike the planets in our Solar System, these objects do not orbit stars, free-floating on their own instead. The new observations, made with the European Southern Observatory’s Very Large Telescope (ESO’s VLT), reveal that this free-floating planet is eating up gas and dust from its surroundings at a rate of six billion tonnes a second. This is the strongest growth rate ever recorded for a rogue planet, or a planet of any kind, providing valuable insights into how they form and grow. “People may think ...

A young rogue planet about 620 light-years away from Earth has experienced a record-breaking “growth spurt,” hoovering up some six billion tons of gas and dust each second over a couple of months.  A team of international researchers have explored changes in the planet’s growth and immediate surroundings. The observations provide insight into how rogue planets—free-floating planetary-mass objects that do not orbit stars—behave and grow in their infancy.   “We’ve caught this newborn rogue planet in the act of gobbling ...

What if the presence of a well-known but misunderstood viral protein explains why some people living with HIV (PLWH) never recover their health, even with antiretroviral treatment? Dr. Madeleine Durand and Andrés Finzi, researchers at the CRCHUM, Université de Montréal’s affiliated hospital research centre, will explore this through the launch of a groundbreaking clinical trial this fall. Two studies, one approach With the publication of a remarkable study in 2023, the two scientists and Mehdi Benlarbi, a PhD student in Finzi’s lab, showed a keen interest in the HIV molecule gp120. The virus is known to infect ...

With the rollout of fifth-generation (5G) telecommunications networks and 6G looming on the horizon, the demand for advanced materials that can handle high-frequency signals is rising rapidly. These systems use electromagnetic waves ranging from tens to hundreds of gigahertz (GHz), where signals are highly sensitive to transmission loss, interference, and distortion. To address these issues, scientists and engineers rely on special insulating materials, known as dielectrics, which help guide signals with minimal loss. Polymer-based dielectrics are particularly attractive. ...

Residential heating, ventilation, and air conditioning (HVAC) systems constitute a significant proportion of energy usage in buildings, necessitating energy management optimization. In this context, occupancy aware HVAC control is a promising option with 20-50% energy savings in homes. However, occupancy sensing technology suffers from long payback times, privacy issues, and poor comfort. Moreover, there is an increasing need for further advanced technologies that help regulate indoor air quality in addition to energy control. To meet these expectations, scientists have recently turned to intelligent control methods such as ...

HOUSTON – Oct. 2, 2025 – Obesity has long been acknowledged as a risk factor for a wide range of diseases, but a more precise link between obesity and Alzheimer’s disease has remained a mystery – until now. A first-of-its-kind study from Houston Methodist found that adipose-derived extracellular vesicles, tiny cell-to-cell messengers in the body, can signal the buildup of amyloid-β plaque in obese individuals. These plaques are a key feature of Alzheimer’s disease. The study, “Decoding Adipose–Brain Crosstalk: Distinct Lipid Cargo in Human Adipose-Derived ...
