In Alzheimer’s disease, proteins like amyloid beta form clumps, known as plaques, that damage the brain.

But in some people, immune cells called microglia break down these proteins before they can cause harm. This leads to fewer and smaller clumps — and much milder symptoms.

Researchers at UC San Francisco identified a…

The new substance repels both water and grease about as well as standard non-stick coatings — but it contains much lower amounts of per- and polyfluoroalkyl substances (PFAS), a family of chemicals that have raised environmental and health concerns.

“The research community has been trying to develop safer…

Dementias such as Alzheimer’s disease are estimated to affect more than 57.4 million people worldwide, a number that is expected to almost triple to 152.8 million cases by 2050. The impacts on the individuals, families and caregivers and society at large are immense.

While there are some…

il 7000 steps, at which point the benefits began to taper off

A major new study led by the University of Sydney suggests that walking 7000 steps a day offers similar health benefits across several outcomes as walking 10,000.

Led by Professor Melody Ding from the School of Public Health, the study was published in The Lancet Public…

Sexual satisfaction may be one of the most overlooked predictors of healthy aging, and new research suggests it plays a far greater role in longevity and emotional well-being than most people realize. In a 2024 analysis published in Sexuality Research and Social Policy, scientists found that sexual fulfillment is strongly linked to how well adults adjust to aging, influencing key markers of vitality, such as purpose, physical self-perception,…

If motivation feels harder to access, sex drive has dipped, or attention span is fleeting, dopamine could be the missing piece. Dopamine, often dubbed the “motivation molecule,” is paramount to how we experience pleasure, learn new behaviors and pursue goals.

But in our hyper-digitized world, we may be numbing the very system we rely on to feel engaged, alive and alert. From endless algorithmic feeds to…

Complex economic forces shape the U.S. healthcare landscape, with private equity (PE) firms promising efficiency and growth in the medical sector while simultaneously sparking debate. On June 9, 2025, Oregon Governor Tina Kotek signed Senate Bill 951 (SB 951) into law, representing the most recent and stringent legislative effort to restrict private equity investment in healthcare.

What does the rise of private equity mean for healthcare?…

The researchers published their findings in the International Journal of Molecular Sciences.

“Globally, the incidence and mortality rates of pancreatic cancer continue to rise, with a five-year survival rate of less than…

By drawing on genetic data from over five million people, an international team of researchers has created a genetic test called a polygenic risk score (PGS) that predicts adulthood obesity already…
