A large study found that people who are overweight or obese when diagnosed with dementia have a significantly lower risk of death than those at a normal weight. A higher body weight at the time of a dementia diagnosis may be linked to longer survival, according to a large study of older Americans. Researchers found […]
One-Third of Older Adults With Cognitive Disorders Take Drugs That Could Harm Them
As the population ages, medication safety is becoming increasingly important for people with cognitive decline. Older adults with dementia and other cognitive disorders are less likely than they were a decade ago to receive medications that can worsen memory, balance, and coordination. But nearly one in three still takes at least one potentially inappropriate drug. […]
The Fossil Record May Be Missing 200 Million Years of Animal History
By the time animals left their first unmistakable fossils, they may already have had up to 200 million years of evolutionary history behind them. A fossil deposit in Mongolia preserves microscopic organisms in extraordinary detail, down to cells inside specimens that resemble embryos. Yet none of the fossils examined can confidently be identified as an […]

Scientists Predicted Humanity Would End on November 13, 2026. Should We Be Worried?
For decades, a doomsday equation predicted population growth better than most experts, until falling birth rates undermined its forecast of catastrophe in 2026. In 1960, Science, one of the world’s leading science journals, published an article with an unambiguous title: Doomsday: Friday, 13 November, A.D. 2026. It predicted that on this future date—just over a […]
Experimental Heart Drug Helps Patients Exercise More and Feel Better
In a new trial, an experimental drug helped patients with an inherited heart muscle condition feel better and exercise more. Two new studies found that aficamten improved exercise capacity and reported health in people with nonobstructive hypertrophic cardiomyopathy (nHCM). This inherited condition thickens and stiffens the heart muscle, often causing shortness of breath and limiting […]
