PULLMAN, Wash. — Promoting women’s ownership in wineries can boost sales among the largest group of U.S. wine consumers, who happen to be women. Messages like “proudly made by a woman winemaker” increased women’s intentions of purchasing wines, particularly when the label’s artwork reinforced the point with feminine gender cues such as flowers. Women were also willing to pay higher prices for those wines, according to the research from Washington State University and Auburn University. The findings are noteworthy because 59% of all wine purchases in the United States are made ...

Liquid crystal monomers (LCMs) are critical components of laptop, television and smartphone screens. Given their ubiquity in the environment, these compounds are considered persistent pollutants, posing threats to marine life that scientists want to understand. Research published in ACS’ Environmental Science & Technology provides initial evidence that LCMs from household electronics or electronic waste (e-waste) can accumulate in dolphin and porpoise tissues, including blubber, muscle, and brain, demonstrating ...

Over the years, cell biology has built a detailed picture of how cells compartmentalize their internal functions. Central to this organization is the nucleus, which houses the genetic material and is separated from the cytoplasm by a robust nuclear envelope. Traditionally, the nuclear membrane has been considered a strict barrier, maintaining nuclear integrity except during carefully controlled processes such as mitosis. As a result, the release of nuclear material has largely been associated with cellular damage or ...

Wearable sensors are rapidly advancing, becoming smaller yet more capable than ever of tracking physiological signals in real time. Recent studies have focused on developing skin patches that analyze sweat to monitor the concentration of important compounds, such as lactate and glucose. Sweat-based sensing is particularly attractive because it offers a noninvasive way to assess changes in metabolism. However, these devices require external batteries to function. Interestingly, to avoid relying on batteries, scientists have come up with self-powered alternatives. Enzymatic ...

Statement Highlights: Over the next 25 years, the number of women living with cardiovascular disease is expected to rise sharply, as nearly 60% of women in the U.S. could have high blood pressure by 2050, up from about 5 in 10 previously reported for 2020, according to projections outlined in a new scientific statement from the American Heart Association. Nearly a third of all women 22-44 years of age will have some type of cardiovascular disease, compared to less than 1 in 4 currently. The rise in cardiovascular disease will also be fueled ...

Embargoed copy of the research paper available on request While air-conditioning protects people from dangerous heat, it also significantly worsens global warming – by 2050 potentially producing more carbon dioxide than the current annual emissions of the United States, a new study reveals. Scientists have combined climate science, energy modelling, and inequality analysis to create a unique framework using a set of well‑established global ‘storylines’ — Shared Socioeconomic Pathways and Representative Concentration Pathways (SSP and RCP scenarios) — a set of ‘futures’ ranging from strong climate action to high emissions. The study reveals ...

To be healthy, conventional wisdom tells us to exercise and limit fatty foods. Exercise helps us lose weight and build muscle. It makes our hearts stronger and boosts how we take in and use oxygen for energy — one of the strongest predictors of health and longevity. But people with high blood sugar often don’t achieve those benefits from exercise, especially the ability to use oxygen efficiently. They’re at higher risk for heart and kidney disease, but high blood sugar can prevent their muscles from taking up oxygen more effectively in response to exercise.  For them, a new study ...

Solutions to the plastic waste crisis are often pitched using words that can skew value judgements, new research argues. The paper, authored by the Sustainable Materials Innovation Hub at The University of Manchester, explores the consequences of terminology choices on end-of-life solutions for plastic waste.  While recycling has long been touted as a solution for plastic sustainability - it comes in many forms, and can sometimes serve as a smokescreen for genuine discussions around sustainability. The researchers, Seiztinger, Lahive, and Shaver, ...

MIAMI — A new study provides a comprehensive global synthesis of how vessel traffic affects large marine wildlife, including whales, dolphins, seals, manatees, sea turtles, sharks and rays. Drawing on over four decades of published scientific research, the meta-analysis combined findings from more than 200 peer-reviewed studies conducted around the world. In total, nearly 1,900 comparisons were compiled between scenarios with and without vessel presence, allowing for a robust assessment of how vessels impact marine wildlife. The analysis examined documented responses to vessel activity across various ...

Researchers at IMDEA Networks Institute, together with European partners, have found that tire pressure sensors in modern cars can unintentionally expose drivers to tracking. Over a ten-week study, they collected signals from more than 20,000 vehicles, revealing a hidden privacy risk and highlighting the need for stronger security measures in future vehicle sensor systems. Most modern cars are equipped with a Tire Pressure Monitoring System (TPMS), mandatory since the late 2000s in many countries for their contribution to road safety. This system uses ...

According to a new study by the Museo Nacional de Ciencias Naturales (MNCN-CSIC) and the National University of Colombia, chronic ocean warming is driving a nearly 20% annual decline in fish biomass. However, the researchers found that extreme marine heatwaves can sometimes mask this trend by causing temporary population increases in certain areas. The research, conducted in the waters of the Mediterranean, the North Atlantic, and the Northeastern Pacific, is based on the analysis of 702,037 estimates of biomass change from 33,990 fish populations recorded between 1993 and 2021 in the Northern ...

Green hydrogen is considered to be an important part of the global climate transition, especially as a fuel and energy carrier for heavy transport and industry. However, large-scale green hydrogen production requires sustainable ways of managing water resources to avoid giving rise to water shortages and conflicts with agriculture over access. This has been shown in a unique study from Chalmers University of Technology in Sweden, that connects local water supply with a range of scenarios for future hydrogen needs in Europe. Replacing fossil fuels with hydrogen ...

Researchers at University of California San Diego School of Medicine have developed a new, easy-to-use blood test score that can help identify when fatty liver disease is being driven by excessive alcohol use, an important distinction that often goes unrecognized in routine care. The study results, published in the February 25, 2026 online edition of Gastroenterology, found that a new blood test score could help clinicians determine when liver injury is likely driven by alcohol rather than metabolic factors, providing clearer guidance on when additional alcohol testing may be needed. The tool, called the MetALD-ALD Prediction Index (MAPI), uses five standard lab values that are ...

Almost half of patients hospitalised for acute heart failure in Europe are readmitted within a year, according to a new study led by researchers at Karolinska Institutet and published in the European Heart Journal. The risk of death also remains high, especially for those with more severely reduced heart function. Heart failure is a common condition affecting over 64 million people worldwide. The new study, conducted by an international team and coordinated by Karolinska Institutet in Sweden, analysed data from more than 10,000 patients ...

A study in Health Economics uncovers a major unintended consequence of abortion‐related regulations: a measurable decline in the availability of obstetricians and gynecologists. Since 2010, increasing numbers of states across the US have enacted Targeted Regulation of Abortion Providers (TRAP) laws that require abortion clinics to adhere to stringent and often medically unnecessary standards. By analyzing 2010–2021 data, investigators found that TRAP laws significantly reduced the supply of obstetricians and gynecologists—particularly older and newly trained doctors—without corresponding increases in midwives, nurse practitioners, and physician ...

Muscle loss, or atrophy, due to inactivity is common after illness, injury, hospitalization or falls, and becomes increasingly frequent with aging. New research published in Advanced Science shows that skeletal muscle retains a “molecular memory” of repeated disuse—and that this memory differs markedly between young and old muscles. For the study, researchers combined repeated lower‑limb immobilization in young adults with an aged‑rat model to enable age comparisons. In young adults, repeated disuse resulted in a similar amount of muscle atrophy during both periods; however, the molecular response showed a protective memory. Oxidative and mitochondrial ...
