A new study suggests that reproducing a crucial sleep-like brain pattern in awake animals may help preserve memory and learning abilities. What if part of the brain could get some of the benefits of sleep without the rest of the brain ever going offline? A new NIH-funded study suggests that may be possible. Researchers found [...]

EEG studies suggest caffeine can reduce deep, restorative sleep even when sleep duration appears normal. Its effects vary by individual, and relying on caffeine for energy may come at the cost of nighttime recovery. Evening coffee has long been debated. Some people can drink it and fall asleep with no trouble, while others struggle to [...]

Researchers have created a model that follows food beyond traditional calorie calculations, incorporating the role of gut microbes in digestion. Food labels make calorie counts look straightforward. The number listed per serving is calculated from the food’s fat, carbohydrate, and protein content. In reality, the digestive process is much more complex. As food moves through [...]

People's daily steps might drop after starting a GLP-1 prescription, new research suggests.

Scientists found a concerning Alzheimer’s link involving glucosamine, a joint supplement used by millions. A widely used supplement marketed for joint pain relief may be linked to faster progression of Alzheimer’s disease, according to new research from University of Florida scientists. The study found that people with mild cognitive impairment (MCI) who reported taking glucosamine [...]

A surprisingly simple action can make a major difference.

The human heart is one of the hardest-working organs in the body. It never takes a day off and requires a continuous supply of energy to keep beating. To meet these enormous energy demands, heart cells mainly rely on fats as fuel. For decades, researchers have viewed this ability to burn fat as a sign […]

Doctors have long treated heart disease and cancer as two separate health problems. Heart specialists focus on the cardiovascular system, while cancer specialists focus on tumors and abnormal cell growth. However, scientists are increasingly finding that these two major diseases may be more closely connected than previously believed. A new study led by researchers at […]

A new soft ultrasound patch is designed to provide long-term, hands-free monitoring of fetal health in real time. Engineers at the University of California, San Diego, have developed a soft, wearable ultrasound patch that can continuously monitor a fetus for hours at a time while maintaining reliable performance even as the fetus and umbilical cord [...]

A newly identified vitamin K-dependent signaling pathway appears to help coordinate communication between key bone cells. Bones may seem like lifeless structures, but they are constantly being torn down and rebuilt. Every day, specialized cells remove old bone while others replace it with new material, a process that keeps the skeleton strong and adaptable throughout [...]

Researchers identified a strong association between GLP-1 medications and reduced rates of multiple substance use disorders, raising new questions about how these drugs may affect the brain’s reward system. What if some of the world’s most popular weight loss drugs are affecting more than appetite? A new study suggests that GLP-1 medications, a class of [...]

For decades, pacemakers have helped millions of people live longer and healthier lives. These small devices are implanted inside the body and send electrical signals to the heart when its natural rhythm becomes too slow or irregular. Pacemakers are considered one of the most successful medical technologies ever developed. They have saved countless lives by […]
