Scientists uncover brain circuits behind putting up a fight or freezing in place: Study may provide clues to disorders including anxiety and phobias

In a study of mice, National Institutes of Health-funded researchers describe a new circuit involved in fine-tuning the brain’s decision either to hide or confront threats. The study, published in Nature, was partially funded by the NIH’s Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative. “Being able to manipulate specific circuits can uncover surprising relationships

Australian stores limit baby formula as China demand hits stocks

One of Australia’s biggest supermarket chains said Wednesday some stores were moving baby formula behind counters and restricting sales as it emerged customers were clearing shelves and selling it online in China for more than double the price. Coles’ decision to take the milk product off aisles follows complaints from worried mothers over supplies and

Trial shows chemotherapy is helping kids live with pulmonary vein stenosis: Adding chemotherapy to a treatment regimen including catheterization and surgery can deter abnormal cellular growth

Pulmonary vein stenosis (PVS) is a rare disease in which abnormal cells build up inside the veins responsible for carrying oxygen-rich blood from the lungs to the heart. It restricts blood flow through these vessels, eventually sealing them off entirely if left untreated. Typically affecting young children, the most severe form of PVS progresses very

Expert consensus finds that higher protein intake benefits adult bone health

A new expert consensus endorsed by the European Society for Clinical and Economical Aspects of Osteoporosis, Osteoarthritis, and Musculoskeletal Diseases (ESCEO) and the International Osteoporosis Foundation (IOF) has reviewed the benefits and safety of dietary protein for bone health, based on analyses of major research studies. The review, published in Osteoporosis International, found that a

Women need to know about the link between the pill and depression

The introduction of the contraceptive pill in the 1960s was a major milestone for female empowerment. It allowed women to separate sex from procreation, and to increase their participation in work outside the home. Now, more than 100 million women worldwide use the oral contraceptive pill to prevent pregnancy or control their menstruation. But the

Gun safety programs do not prevent children from handling firearms: Findings suggest that children do not retain safety skills when encountering a firearm in a real-world scenario

Children who participate in gun safety programs often ignore what they learned when encountering a real firearm, according to a Rutgers School of Nursing study. The report, published recently in Health Promotion Practice, reviewed 10 studies on the effectiveness of strategies for teaching gun safety to children ages 4 to 9. The researchers found such

Centralized infrastructure facilitates medical education research

The Council of Academic Family Medicine Educational Research Alliance has enabled a large number of research teams to conduct meaningful scholarship with a fraction of the usual time and energy. CERA regularly conducts omnibus surveys of key family medicine education leaders, a process that includes collaboration with experienced mentors, centralized institutional review board clearance, pilot

Research leads to medication reduction in aged care facilities

Effective intervention can reduce medication overuse in Residential Aged Care Facilities (RACF’s), the latest University of Tasmania research shows. Led by The Wicking Dementia Research and Education Centre’s Dr. Juanita Westbury, the research published in the Medical Journal of Australia (MJA) today focuses on the results of the RedUSe (Reducing Use of Sedatives) intervention aimed

Neuroscientists find first evidence animals can mentally replay past events: Discovery of episodic memory replay in rats could lead to better treatments for Alzheimer’s disease

Neuroscientists at Indiana University have reported the first evidence that non-human animals can mentally replay past events from memory. The discovery could help advance the development of new drugs to treat Alzheimer’s disease. The study, led by IU professor Jonathon Crystal, appears today in the journal Current Biology. “The reason we’re interested in animal memory

This is why allergy season can leave you feeling exhausted

Well, for the millions of people who suffer from seasonal allergies, the aforementioned springtime air, flora and fauna aren’t quite as much of a delight. In addition

Discovery of differences in the brains of rats classified as workers vs. slackers: Discoveries reveal the brain mechanisms involved in decision-making

A team of researchers led by Dr. Catharine Winstanley at the University of British Columbia have uncovered a network of regions in the brain that are involved in determining the choice of working harder to get a bigger reward, or putting in a lesser effort and receiving a smaller reward. Understanding how the brain makes

Could vitamin D help to fight diabetes?

Currently, there are around 30 million people in the United States living with type 2 diabetes, a lifelong condition that cannot yet be cured. Obesity, one of the major risk factors, is steadily rising, meaning that the number of people with type 2 diabetes is likely to follow suit. The condition is caused by faulty

Reversing atherosclerosis with one shot

Atherosclerosis is a condition in which plaque builds inside the arteries, stiffening and eventually clogging them. Plaque is a waxy substance that’s made of cholesterol, fat, fragments of cellular waste, calcium, and fibrin, an insoluble protein that helps the blood to clot. As plaque gradually builds up inside the arteries, it causes the vessels to
