Why falls are a hidden threat for middle-aged people with long-term disabilities (and what to do about it)

A new study found that middle-aged people living with long-term disabilities experience falls and related injuries at alarmingly high rates. The key insight: fall risk is strongly linked to common disability symptoms like pain, fatigue, and mobility issues — not just age. That means targeted strategies to manage these symptoms could help prevent falls and keep you active and independent longer.

The Silent Threat to Your Parents' Health in Hospitals (And the Simple Fix Doctors Are Missing)

This study across multiple European hospitals found that when medical staff are trained to spot malnutrition in elderly patients, they catch it far more often. The problem is huge—up to half of older hospital patients are malnourished—but most healthcare workers don't see it because they aren't looking. For you, it means that the next time your parent or grandparent is in the hospital, you can know exactly what to ask and advocate for better nutrition care.

A Smarter Way to Fix Cavities? New Material Could Make Fillings Last Longer

Researchers have developed a new material that forms a strong, protective layer on the inside of your tooth, helping fillings bond more tightly and last longer. It works by creating a kind of 'smart glue' that reacts with the tooth's natural surface. While still in early lab testing, this could one day mean fewer failed fillings and less tooth sensitivity.

Your bones might be getting weaker without you knowing it — here’s how to stop it

Osteopenia is a common condition where bones become less dense and more fragile, but it often goes unnoticed until a break happens. Aging, menopause, poor diet, and inactivity are key drivers, but the good news is that exercise, calcium, and vitamin D can slow or even reverse the decline. This matters because catching it early can prevent fractures and keep you active as you age.

You Probably Need More Protein Than You Think — And It Could Help You Stay Strong and Sharp for Decades

A new review of the science argues that current protein recommendations are too low for most people, especially as we age. Eating more protein — combined with regular exercise — may help preserve muscle, brain function, and overall healthspan. The goal isn't a six-pack; it's staying strong enough to enjoy life fully for decades longer.
