People who have ADHD traits at age 10 are more likely than those without such traits to have physical health problems and to report physical health-related disability at age 46, according to a study led by University College London (UCL) and University of Liverpool researchers. The researchers say the findings likely reflect the impact of a wide range of risk factors for poor health that are linked to attention deficit hyperactivity disorder (ADHD) and society’s response to people with ADHD across adulthood. The new JAMA Network Open paper is one ...

Despite guideline recommendations and improved access to care, individuals with hypertension are unlikely to measure their blood pressure at home as often as recommended, according to data from researchers at Mass General Brigham. In a retrospective cohort study, investigators found that even with free blood pressure devices, education, and personalized support, patient engagement with at-home blood pressure monitoring remained low — highlighting the need for more convenient, less burdensome monitoring tools. The findings were published in JAMA Cardiology. Previous research suggests that at-home blood pressure measurements are often more accurate than clinic readings. Current American ...

Demand for lithium is skyrocketing as factories across the world churn out electric vehicles and the massive batteries that make wind turbines and solar panels reliable sources of energy. Unfortunately, current methods for producing lithium are slow and require high-quality feedstocks that are found in relatively few locations on the planet. Ironically, the environmental costs are also significant: refining the mineral behind clean energy requires large amounts of land and pollutes water supplies that local communities depend ...

A research team led by Prof. LI Bing from the Institute of Metal Research of the Chinese Academy of Sciences, together with collaborators, has overcome a longstanding bottleneck in refrigeration technology. Their findings, published in Nature on January 22, introduce a novel cooling method based on the "dissolution barocaloric effect," which offers a promising zero-carbon alternative to traditional refrigeration. Modern civilization relies on refrigeration but at a heavy cost. Traditional vapor-compression cooling consumes large quantities of electricity and produces substantial carbon emissions. Although solid-state cooling has long been considered ...

The atmosphere is an important transport medium that carries microplastics to even the most remote parts of the world. These microplastics can be inhaled and pose a health risk to humans and animals. They can also settle out of the atmosphere and contaminate oceans and soils worldwide. A new study by the Department of Meteorology and Geophysics at the University of Vienna estimates microplastic emissions from land-based and oceanic sources into the atmosphere based on global measurement data and model simulations. The results: over 20 times more microplastic ...

Quantum computers have immense potential because they could perform highly complex calculations much faster than current supercomputers. However, the hurdle to the practical application of quantum computers is just as immense today: the error-prone nature of their hardware. Researchers around the world are therefore working on quantum error correction methods to make the calculations of quantum computers more reliable. Against this backdrop, neQxt GmbH, the Fraunhofer Institute for Applied Solid State ...

Metabolic dysfunction-associated steatotic liver disease (MASLD) and its progressive form, metabolic dysfunction-associated steatohepatitis (MASH), represent the most common chronic liver diseases in Western populations, driven largely by obesity and insulin resistance. MASH can progress to cirrhosis and hepatocellular carcinoma (HCC), with the incidence of MASH-related HCC rising rapidly. While lifestyle modification remains foundational, pharmacological intervention is increasingly important. This review explores the emerging ...

Most research on the health effects of stress focuses on adults, but a new review looks at how stress uniquely affects children. In the most comprehensive review of its kind to date, UC San Francisco researchers found robust evidence that stress occurring as early as before birth or as late as adolescence can affect multiple conditions in kids, from asthma to mental health to cognitive functioning. The results appear Jan. 20 in the Annual Review of Psychology. Among the most important findings: Stress can impact many areas at once — mental ...

Flue gas is exhausted from home furnaces, fireplaces and even industrial plants, and it carries polluting carbon dioxide (CO2) into the atmosphere. To help mitigate these emissions, researchers reporting in ACS Energy Letters have designed a specialized electrode that captures airborne CO2 and directly converts it into a useful chemical material called formic acid. The system performed better than existing electrodes in tests with simulated flue gas and at ambient CO2 concentrations. “This work shows that carbon capture and conversion do not need to be treated as separate steps. By integrating both ...

Ammonia is an essential chemical used across many industries worldwide. Beyond its traditional role as a fertilizer, it is also a promising liquid hydrogen carrier and low-carbon fuel that could help reduce reliance on fossil fuels. However, conventional ammonia production based on the Haber–Bosch (HB) process requires considerable energy and contributes significantly to greenhouse gas emissions, accounting for roughly 1–1.3% of global emissions annually. Given its growing importance, there is an urgent need to reduce the environmental burden of ammonia production. Recently, ...

Physical rehabilitation and symptom management still remain the mainstay of treatment for stroke, as clot removal or dissolution is effective only within a narrow time frame after the stroke. After that, many patients are left with long-term problems like difficulty in walking, speaking, and memory decline. Exercise has been beneficial in preventing strokes and improving recovery. However, the majority of these patients, being elderly, are too frail to exercise enough to gain these benefits.   In an ...

Thermal management is essential for reducing future heating and cooling energy consumption. Notably, the near-infrared (NIR) component of sunlight is closely associated with heat absorption. Hexagonal tungsten oxide nanorods are promising NIR-blocking electrochromic materials that change their color, transparency, and opacity upon the application of a small electric voltage. Their hexagonal tunnels, known as optically active sites, can effectively accommodate electrolyte ions and enable dynamic NIR ...

The language used to describe conflicts naturally reflects assumptions about how different forms of violence emerge and develop. “For instance, we think that 'civil wars' are the result of internal strife, and we debate whether wars should be characterized as matters of 'invasion' or 'defense.' In a similar way, experts also label conflicts to indicate important properties and to make patterns across conflicts comparable for use in systematic analysis, early warning, and ...

Highlights: According to the American Heart Association’s 2026 Heart Disease and Stroke Statistics Update, heart disease remains the leading cause of death in the U.S. and stroke has moved up to the #4 spot. Together, heart disease and stroke accounted for more than a quarter of all deaths in the U.S. in 2023, the most recent year for which data is available. Cardiovascular diseases, including all types of heart disease and stroke, claim more lives in the U.S. each year than all forms of cancer and accidental deaths — the #2 and #3 causes of death — combined.

Scientists from the RIKEN Center for Emergent Matter Science and colleagues have developed a new way to fabricate three-dimensional nanoscale devices from single-crystal materials using a focused ion beam instrument. The group used this new method to carve helical-shaped devices from a topological magnet composed of cobalt, tin, and sulfur, with a chemical formula of Co₃Sn₂S₂, and found that they behave like switchable diodes, meaning that they allow electricity to flow more easily in one direction than the other. Creating ...

Organic chemistry is packed with rules about structure and reactivity, especially when it comes to making and breaking chemical bonds. The rules governing how these bonds, which hold atoms together in molecules, form and the shapes they give molecules are often thought to be absolute, but UCLA organic chemists are pushing the boundaries of the possible.   In 2024, Neil Garg’s lab violated Bredt’s rule, a 100-year-old rule stating that molecules cannot have a carbon-carbon double bond at the “bridgehead” position (the ring junction of a bridged bicyclic molecule). Now, they’ve developed the chemistry of ...
