We all get anxious from time to time, but what happens in the brain when this dreaded feeling looms? New research helps to answer this question.
In a study of monkeys, Ilya Monosov, Ph.D., of the Departments of Neuroscience and Biomedical Engineering at Washington University in St. Louis, MO, discovered specific...
Scientists have discovered a cell mechanism involving the hormone leptin that plays a key role in the formation of new blood vessels. The discovery may help to develop treatments that stimulate tissue repair following a heart attack, as well as treatments that stop abnormal tissue growth, such as in cancer.
A...
A recent meta-analysis published in the Journal of the American Geriatrics Society investigates tai chi as a way to reduce the risk of falling among older adults. This ancient art could help to improve the lives of modern at-risk individuals.
Falls are a serious risk for older adults. According to the...
Trouble getting enough sleep may be linked to a bigger risk of Alzheimer’s disease for some people, new research suggests.
The results of the small study hint that people with a higher-than-normal risk of Alzheimer’s disease who had worse sleep quality, more sleep problems and daytime sleepiness had more markers for...
It says that broccoli can help control diabetes
Some people don’t like to eat their vegetables, but for obese people with type 2 diabetes, broccoli could hold the key to slowing, and potentially reversing, the disease, according to a new study.
Scientists used both computational and experimental research to zero in on...
Heart failure patients are much less likely now to die from sudden cardiac arrest, new research shows.
Rates of sudden death from heart failure have declined by nearly half over the past two decades, according to data gathered from a dozen separate clinical trials.
Better heart medications used in effective combinations are...
The concept behind tissue engineering is simple: grow the patient’s stem cells in the laboratory, add them to a scaffold material, and you have a laboratory-grown organ. But few patients have benefited from this technology so far. Could change be on the horizon?
Scientific studies are frequently hailed as bringing novel,...
It’s a shocking reality for millions of people across the country: They go for a routine physical exam only to find out they’ve had a heart attack that happened days, weeks or months earlier.
About half of all heart attacks are silent, meaning the symptoms are so subtle, the person didn’t...
If you think preschool is all about playing with dolls and blocks, think again. There’s a growing trend toward more rigorous, scholarly preschools—and a new study supports the idea, finding that children who attended a year at an “academic-oriented” preschool were performing better academically by the end of kindergarten.
Specifically, the...
A moderate-intensity walking regimen may reduce symptoms of mild cognitive impairment that are linked to poor blood vessel health in the brain, a small study suggests.
Participants with vascular cognitive impairment, sometimes called vascular dementia, who walked three hours per week for six months had improved reaction times and other signs...
