Between feeding everyone, picking up and dropping off kids at their various activities and tackling the seemingly never-ending heap of laundry, it’s hard for parents to carve out time for sleep, let alone for a hobby. But making time to do something you enjoy […]

Scientists show how brain circuit generates anxiety

Neuroscientists at Cold Spring Harbor Laboratory (CSHL) have identified a neural circuit in the amygdala, the brain’s seat of emotion processing, that gives rise to anxiety. Their insight has revealed the critical role of a molecule called dynorphin, which could serve as a target for treatment of anxiety-related disorders including post-traumatic stress disorder (PTSD). Though they are distinct, fear and […]

Impaired energy production may explain why brain is susceptible to age-related diseases

Defective energy production in old neurons might explain why our brains are so prone to age-related diseases. Salk researchers used a new method to discover that cells from older individuals had impaired mitochondria—the power stations of cells—and reduced energy production. A better understanding of the effects of aging on mitochondria could reveal more about the link between mitochondrial dysfunction and […]

A key switch in biological clocks

Just as we abide by an external time schedule to eat, sleep, and go to work, our body is similarly dictated by internal clocks. Known as circadian rhythms, these daily cycles keep us on a regular 24-hour day and are involved in numerous aspects of our well-being. When these biological clocks fail to work as they should, our bodies are […]

High protein diet associated with small increased heart failure risk in middle-aged men

For middle-aged men, eating higher amounts of protein was associated with a slightly elevated risk for heart failure than those who ate less protein, according to new research in Circulation: Heart Failure, an American Heart Association journal. Despite the popularity of high protein diets, there is little research about how diets high in protein might impact men’s heart failure risk. […]

Assessment of biomarkers of subconcussive head trauma

Researchers from The Sport Science Center at Texas Christian University, Texas Health Sports Medicine, and the University of Wisconsin-La Crosse evaluated the usefulness of biomarker testing in determining the potential extent of brain trauma suffered from repetitive subconcussive head impacts sustained over the course of a college football season. Their findings are reported today in the Journal of Neurosurgery, in […]

Report identifies characteristics of microorganisms most likely to cause a global pandemic

Infectious disease preparedness work focuses predominantly on an historical list of pathogens derived from biological warfare agents, political considerations, and recent outbreaks. That fails to account for the most serious agents not currently known or without historical precedent, write scholars from the Johns Hopkins Center for Health Security in a new report on the traits of microorganisms with high pandemic […]
