Scientists have uncovered sweeping changes in how the human brain controls and organizes its genome beginning in midlife, offering new clues to why aging sharply increases the risk of Alzheimer's and other neurodegenerative diseases. One of the ...

The flesh eating New World screwworm has returned to the United States, threatening livestock, wildlife, pets and potentially people as it spreads north. A new UC San Diego tracking system aims to predict where the parasite could strike next while .. ...

A major analysis of 139 clinical trials involving nearly 10,000 people suggests that some of the simplest treatments may work best for knee osteoarthritis. Knee braces ranked highest overall for reducing pain, stiffness, and mobility problems, while ...

A newly discovered communication system in the microscopic "antennae" of cells may help explain how some congenital heart defects develop. When genetic mutations disrupt this system, the effects may extend beyond the heart to organs including the ...

Ancient DNA reveals that plague was already killing hunter-gatherers in Siberia 5,500 years ago, long before cities and flea-driven epidemics. The prehistoric strains may have been especially dangerous because they carried a genetic factor capable of ...

Cancer rates are rising in adults under 55, and new research suggests accelerated biological aging may be one piece of the puzzle. Scientists found that people from more recent generations tended to have bodies that appeared biologically older than . ...

Scientists have discovered that the brain's short-range wiring may help protect cognition even as gray matter shrinks with age. Healthier connections just beneath the brain's surface were linked to better language skills and appeared to weaken the .. ...

A wearable device has revealed nighttime hormone surges that may expose a frequently missed cause of high blood pressure. The discovery could help explain why primary aldosteronism often escapes standard blood tests and point toward a more accurate . ...

Low vitamin D levels may make recovery from breast cancer surgery more painful, according to a study of 184 women undergoing mastectomy. Patients with vitamin D deficiency were three times more likely to experience moderate to severe pain during the ...

Scientists discovered that aging cells can use malfunctioning mitochondria to unlock inflammatory genes and keep the immune system stuck in a prolonged state of alert. Blocking one part of this process reduced inflammation and improved healthy aging ...
