Researchers at Washington University School of Medicine in St. Louis have received an $80 million grant to continue research into the mysteries of exceptional longevity. The grant renews support for the Long Life Family Study, a long-running, international investigation of multiple generations of families with unusually high numbers of individuals who have lived much longer than statistical models predict, including some to age 100 and beyond. The work is supported by the National Institute on Aging of the National Institutes of Health (NIH). Launched in 2004, the Long Life Family Study has built on WashU Medicine’s ...

Researchers at the Indian Institute of Technology Gandhinagar (IITGN), in collaboration with international partners, have shown that ocean temperature patterns help limit the global spread of droughts. Published in Communications Earth & Environment, the study analysed climate data from 1901–2020 and found that synchronised droughts affected between 1.8% and 6.5% of global land, far lower than earlier claims that one-sixth of the planet could dry out at once. The study, led by Dr Udit Bhatia, with co-authors from IITGN and the Helmholtz ...

A team of scientists led by the German Centre for Integrative Biodiversity Research (iDiv), the Helmholtz Centre for Environmental Research (UFZ), and Leipzig University has developed a new method to track the Earth’s greenness – a key indicator of vegetation health and activity – by calculating its centre of mass. Lead author Prof. Miguel Mahecha explains: “Imagine holding a perfectly round globe in your hands and attaching small weights to it, each representing the green leaves at every point on the Earth’s surface. If you then carefully place this globe into calm water, the centre of mass will ...

Even people who are only barely altruistic still choose to self-isolate when infected, suggesting it may be a natural survival strategy, finds new University of Warwick led study. Reducing social contact is widely understood to slow disease spread, but because there is no personal health benefit gain from self-isolating, this would seem to require some concern for others. But how much do you have to care about others before you would choose to self-isolate when sick?  Published ...

EMBARGO February 23, 2026 at 3:00 PM U.S. Eastern time Over 40,000 years ago, our early ancestors were already carving signs into tools and sculptures. According to a new analysis by linguist Christian Bentz at Saarland University and archaeologist Ewa Dutkiewicz at the Museum für Vor- und Frühgeschichte (Museum of Prehistory and Early History) in Berlin, these sign sequences have the same level of complexity and information density as the earliest proto-cuneiform script that emerged tens of thousands of years later, around 3,000 B.C.E. Using a ...

CAMBRIDGE, MA -- Volcanoes and wildfires can inject millions of tons of gases and aerosol particles into the air, affecting temperatures on a global scale. But picking out the specific impact of individual events against a background of many contributing factors is like listening for one person’s voice from across a crowded concourse. MIT scientists now have a way to quiet the noise and identify the specific signal of wildfires and volcanic eruptions, including their effects on Earth’s global atmospheric temperatures. In a study appearing this week in the Proceedings of the National Academy of Sciences, the researchers report that ...

COLUMBUS, Ohio – Pickup basketball and neighborhood kickball are less common now than for generations past, giving way to more organized and formal youth sports intended to help kids get ahead, a new study suggests. Researchers found that compared to people born in earlier decades, youths born in the 1990s spent more of their recreational time playing formal sports – coached by adults and wearing uniforms – than with friends and neighbors playing informal matchups organized by kids. “Overall, there’s been a pretty healthy mix across generations and among our respondents in playing both informal and formally organized sports, ...

LEDs no wider than a human hair could soon take on work traditionally handled by lasers, from moving data inside server racks to powering next-generation displays. New research co-authored by UC Santa Barbara doctoral student Roark Chao points to a practical path forward. “We’re talking about devices that are literally the size of a hair follicle,” said Chao, who studies electrical engineering. “If you can engineer how the light comes out, those microLEDs can start to replace lasers in short-distance data communication.” The work builds on UCSB’s longstanding strengths in gallium nitride research and optoelectronics. Chao is co-advised by Steven ...

AURORA, Colo. (February 23, 2026) – A 13-year study led by the Colorado School of Public Health at the University of Colorado Anschutz reveals why a deadly parasitic infection targeted for elimination in China persisted in some areas even after decades of control. The research, which used artificial intelligence (AI) and classic “shoe-leather” investigations, investigated some of the last pockets of disease in the country. They found that farming practices and unsafe sanitation contributed to disease spread. Additionally, as the region approached ...

NEW ORLEANS – Ochsner MD Anderson Cancer Center at The Gayle and Tom Benson Cancer Center in New Orleans announces a milestone in advanced cancer treatment, as the first institution in Louisiana to provide an adult patient with tumor-infiltrating lymphocytes (TIL) therapy for advanced melanoma.   Advanced melanoma is classified as stage III or IV metastatic melanoma and is a form of skin cancer that has spread ...

Superhydrophobic surfaces — those famously “never-wet” materials that make water bead up and roll away — have a stubborn weakness: hot water. Once temperatures climb above roughly 40 degrees Celsius, many superhydrophobic coatings abruptly lose their magic. Instead of skittering off, hot droplets start sticking, soaking into the surface texture and leaving behind wet patches and residue. A new study from mechanical engineers at Rice University describes a surprisingly straightforward ...

Research shows that as individuals learn and acquire a new skill, their brain structure and activity changes. But how do more complex skills involving multiple learning processes influence the brain? New from JNeurosci, researchers led by Erik Wing, from Baycrest Hospital, compared the brains of 29 expert birders with 29 age- and sex-matched beginners. Because birding requires a keen eye, attention, and strong memory, this work may have implications for ...

Researchers at the University of Waterloo have discovered a way to turn plastic waste into acetic acid, the main ingredient of vinegar, using sunlight.  The breakthrough offers a promising new approach to reducing plastic pollution through photocatalysis, while simultaneously creating a useful, value-added chemical product through a process inspired by nature.  “Our goal was to solve the plastic pollution challenge by converting microplastic waste into high-value products using sunlight,” said Dr. Yimin Wu, a professor of mechanical and mechatronics engineering and ...

An attractive influencer couple chats in a kitchen as they prepare dinner. A wine bottle sits on the counter. Someone takes a sip. It looks less like an ad than a slice of ordinary life, the kind of moment that can pass unnoticed during an aimless scroll on social media. But a randomized experiment from Rutgers Health and Harvard University suggests those casual cues matter. Young adults who viewed influencer posts with alcohol were significantly more likely to desire a drink than peers who watched similar posts – from the same influencers – with no alcohol involved. The study in JAMA Pediatrics, led by Jon-Patrick Allem, an associate professor at the Rutgers School ...

About The Study: Exposure to alcohol-promoting social media content was associated with desire to drink across varying levels of prior alcohol use, and social media influencers may contribute to normalization of alcohol consumption among young people. This experimental evidence adds to a growing body of research showing that exposure to alcohol-promoting content, particularly on social media, is associated with alcohol-promoting attitudes and behaviors in young adults.  Corresponding Author: To contact the corresponding author, Jon-Patrick Allem, PhD, MA, email jon.patrick.allem@rutgers.edu.

New research from UCLA Health suggests that certain inhalers used to treat chronic obstructive pulmonary disease (COPD) are not only less harmful to the environment but can also lead to slightly better patient outcomes. Inhalers are essential therapies for COPD and other lung conditions, but many commonly used devices rely on propellants that are potent greenhouse gases. The study, published in JAMA Internal Medicine, found that inhalers with a lower carbon footprint in one commonly used therapeutic class—the combined long-acting muscarinic ...

Plants have an immune system, like people, and when it is triggered by threats like disease or pests, a plant's defenses are activated. But there’s a downside to this protective mechanism: The plant’s growth is suppressed when its immune system is turned on. Colorado State University researchers have found a way to boost a plant’s growth while maintaining its immunity through a hormone treatment that shows promise for food production. A plant threatened by disease will defend itself by producing hormones that can keep the plant alive but also stunt its growth – which is a problem if the plant is needed for ...

FOR IMMEDIATE RELEASE In a new Johns Hopkins Medicine study, researchers found that male and female patients with early Lyme disease present with different signs of the disease in the symptoms they report, their physical exams and their laboratory test results. The study was published on February 7 in Clinical and Experimental Medicine. Researchers found that males were more likely to have a positive test and to have more obvious, severe disease indicators, including other laboratory abnormalities, at diagnosis, yet there were ...

Can students be the front lines of conservation? A new Canada-wide study, published in Metabarcoding and Metagenomics, suggests they can. The efforts of some 5000 students produced data detailed enough to reveal complex ecological networks hidden inside a small PVC and cardboard tube home. Cavity-nesting bees and wasps play key roles in pollination and pest control, yet their distributions and feeding relationships are often poorly known because they can be small, secretive and difficult to observe directly. As part of the Bees@Schools community science program, Sage Handler (University of Guelph), Nigel ...

SAN ANTONIO — February 23, 2026 — Southwest Research Institute (SwRI) continues to expand its unique drug synthesis capabilities and expertise to advance the scalable manufacturing of safer antidotes to combat exposure to organophosphorus nerve agents (OPNAs) and pesticides. Unlike existing manufacturing processes, SwRI’s novel approach avoids cancer-causing compounds during synthesis of oxime antidotes HI-6, Obidoxime and HLö 7. This makes for safer antidotes and supports the kilogram-scale manufacturing needed to sustain a domestic supply of OPNA antidotes for the United States military. End-to-end antidote production in the U.S. ...
