Concurrent physical frailty and depression likely boost the risk of dementia in older people, with the interaction of these 2 factors alone contributing around 17% of the overall risk, suggest the findings of a large international study, published in the open access journal General Psychiatry.   Globally, some 57 million people are living with dementia—a figure that is expected to triple by 2050, note the researchers.    Previously published research has primarily focused on the individual associations between physical frailty or depression and dementia risk, despite the fact ...

Children living in substandard housing in England miss 15 more school days and achieve worse test scores in English and maths than their peers living in better quality housing, suggests research published online in the Journal of Epidemiology & Community Health.   Improving their living conditions—specifically reducing overcrowding and damp, and upgrading heating systems—may not only benefit their health, but also their grades,conclude the researchers.   One in 7 families in England live in homes that fail to meet the official decent homes standard, point out the researchers. Housing is a key determinant of child health, yet relatively little is ...

There is little awareness, particularly among clinicians, of the medical and psychological complexities of ‘topical steroid withdrawal’—the body’s adverse response to the prolonged use of these powerful creams to treat inflammatory skin conditions when they are either tapered or suddenly stopped—warn doctors in the journal BMJ Case Reports.   The condition, also known as ‘TSW syndrome,’ ‘steroid addiction,’ and ‘red burning skin syndrome,’ is poorly ...

Most (79%) of NHS trusts in England are treating patients in corridors or makeshift areas in emergency departments including “fit to sit” rooms, x-ray waiting areas, and in one case a café, finds an investigation published by The BMJ today. Data obtained by The BMJ show that such practices have resulted in at least half a million patients being cared for in temporary spaces and that in some trusts one in four patients in accident and emergency (A&E) departments were cared for in corridors last year. Corridor care refers to the practice of providing care to patients ...

Scientists using NASA’s James Webb Space Telescope have observed an entirely new type of exoplanet whose atmospheric composition challenges our understanding of how this type of planet forms.  This bizarre, lemon-shaped body, possibly containing diamonds at its core, blurs the line between planets and stars.  Officially named PSR J2322-2650b, this object has an exotic helium-and-carbon-dominated atmosphere unlike any ever seen before. It has a mass about the same as Jupiter, but soot clouds float through the air—and deep within the planet, these carbon clouds can condense and form diamonds. It orbits a rapidly ...

The gut microbiome is intimately linked to human health and weight. Differences in the gut microbiome—the bacteria and fungi in the gut—are associated with obesity and weight gain, raising the possibility that changing the microbiome could improve health. But any given person’s gut contains hundreds of different microbial species, making it difficult to tell which species could help. Now, research at the University of Utah has identified a specific type of gut bacteria, called Turicibacter, that improves metabolic health and reduces weight gain in mice on a high-fat diet. People with obesity ...

Electronic medical records (EMRs) have been a tremendous benefit in exam rooms across the country, creating secure patient history databases that clinicians can easily access and update. Yet, they can also detract from the doctor-patient experience, as physicians must type notes into the system rather than devote their complete attention to patients. To help put physicians back in front of their patients — and away from their keyboards — UC Davis Health has adopted an artificial intelligence (AI) scribe, which automatically records and ...

NEW ORLEANS — The oceanic conditions that churn up the very strongest of hurricanes and typhoons are heating up in the North Atlantic and Western Pacific, fueled by warm water that extends well below the surface. Human-caused climate change may be responsible for up to 70% of the growth of storm-brewing hotspots there, according to new research.   These hot spots are making it more likely that stronger Category ‘6’ tropical cyclones may hit landfall in highly populated areas.   “The hot spot regions ...

Once the domain of buttons and knobs, car dashboards are increasingly home to large touch screens. While that makes following a mapping app easier, it also means drivers can’t feel their way to a control; they have to look. But how does that visual component affect driving? New research from the University of Washington and Toyota Research Institute, or TRI, explores how drivers balance driving and using touch screens while distracted. In the study, participants drove in a vehicle simulator, ...

St. Louis, MO — Researchers at Saint Louis University School of Medicine say deaths from alcohol-related liver disease have surged in recent years, and the increase is hitting people without a college degree the hardest. While nearly every demographic group is seeing higher death rates—including those with college degrees—the gap between economically disadvantaged groups and more affluent ones is growing, according to new research published in Alcohol: Clinical & Experimental Research. Alcohol-related liver disease is one of the leading causes of death in the U.S. Experts say its growing impact ...

As microplastics accumulate in soils, waters, and even the human body, scientists are racing to understand how these persistent pollutants can be safely removed from the environment. A new review published in New Contaminants highlights a critical but often overlooked factor in this challenge: temperature. The study examines how high and extreme temperatures influence the ability of microorganisms to degrade microplastics. Drawing on evidence from laboratory studies, natural hot environments, and industrial systems, the authors show that heat can both accelerate and suppress microbial breakdown of plastic particles, depending on conditions ...

Plants do not rely only on their leaves to feed on carbon dioxide. A new study in Carbon Research reveals that maize roots can act as an active “second mouth” for carbon, taking up CO2 from the soil and helping regulate the carbon cycle between soil, plants and the air. A new look at plant carbon For decades, biology textbooks have emphasized that plants absorb CO2 only through chlorophyll containing leaves. The new research challenges this simplified view by showing that roots can also absorb CO2 from the soil atmosphere under certain conditions. This underground carbon intake ...

FAMU-FSU College of Engineering researchers are applying fuel cell technology to new applications like sustainable energy and water treatment. In a study published in Frontiers in Membrane Science and Technology, the researchers examined a type of membrane called a perfluorosulfonic acid polymer membrane, or PFSA polymer membrane. These membranes act as filters, allowing protons to move through, but blocking electrons and gases. In the study, the researchers examined how boiling these membranes — a common treatment applied to the material — affects their performance and helps them work as specialized tools for ...

The Global Initiative for Chronic Obstructive Lung Disease (GOLD) congratulates UN Member States for recognizing that chronic obstructive pulmonary disease(COPD) is a major cause of disability and death requiring urgent action and welcomes the call for increased access to diagnosis and inhaled medicines included in the Political Declaration.  480 million people live with COPD, and 3.7 million die each year.  COPD is the third commonest cause of death globally.  It also creates massive economic costs and a recent study estimated ...

(MEMPHIS, Tenn. – December 16, 2025) St. Jude Children’s Research Hospital scientists identified a promising combination approach to treat a rare, but catastrophic pediatric brain cancer called atypical teratoid rhabdoid tumor (ATRT). Reactivating and maintaining p53, a protein responsible for tumor suppression, using the drugs idasantulin and selinexor, respectively, was well-tolerated, reduced tumor burden and increased survival in a laboratory model. Further, the researchers identified a route by which cells may develop resistance to the combination and outlined strategies to offset this phenomenon. The findings were published in Neuro-Oncology ...

A new study led by scientists from the University of Hawaiʻi (UH) Mānoa Hawaiʻi Institute of Marine Biology (HIMB) Shark Lab reveals a critical link between seasonal seabird nesting and the movements of top marine predators in the remote Northwestern Hawaiian Islands. The research, published this month in the journal Ecosphere, found that the annual summer arrival of fledgling seabirds at French Frigate Shoals (FFS) concentrates tiger sharks in specific areas, forcing other species, including gray reef and Galapagos sharks, to drastically shift their own habitat use to avoid predation and competition. The discovery highlights a profound, indirect connection between terrestrial ...

Legalized sports betting comes with a hidden public safety cost: a measurable rise in violent and impulsive crime on game days––even in states without gambling, according to new research led by the University of Michigan.   Researchers from U-M and Rice University analyzed crime incident data from 2017 to 2021 and found that states that legalized sports betting after the 2018 Supreme Court decision in Murphy v. NCAA saw significant increases in assaults, larceny and vehicle theft during and immediately following professional sports games. Crime levels ...

Scientists at NYU Abu Dhabi have developed a powerful new artificial intelligence tool called LA⁴SR that can rapidly identify previously overlooked proteins in microalgae - tiny organisms that produce much of the Earth’s oxygen and support entire aquatic ecosystems. This breakthrough will allow scientists to speed up the search for new natural compounds and enzymes that could support future clean energy solutions. It will also help researchers better understand how microscopic life adapts to changing environments and open new possibilities for monitoring water quality and tracking how ecosystems respond to climate shifts. Microalgae are essential ...
