In a study published in the journal Neurology of almost 700 people born in 1936, researchers found physically active people showed fewer signs of brain shrinkage and other deterioration than those who got less exercise. At the same time, social and intellectual activities such as visiting family and friends, reading, playing intellectually stimulating games or…
Are you overcome by ophidiophobia when you come across a snake in the wild? As it turns out, the abnormal fear of snakes, or other phobias, can alter how we think and perceive the world. “Our results show that emotion and perception are not fully dissociable in the mind,” said Emory psychologist Stella Lourenco, Ph.D.,…
A University of British Columbia and Centre for Molecular Medicine and Therapeutics study has revealed that childhood poverty, stress as an adult, and demographics such as age, sex and ethnicity, all leave an imprint on a person’s genes. And, that this imprint could play a role in our immune response. The study was published in…
Creativity is often part of a mental illness, with writers particularly susceptible, according to a study of more than a million people. Writers had a higher risk of anxiety and bipolar disorders, schizophrenia, unipolar depression, and substance abuse, the Swedish researchers at the Karolinska Institute found.

Rapid urbanization will take a heavy toll on public health if city planning and development do not incorporate measures to tackle air pollution, warns a new study.

It’s been 3 years since the legality of federal funding for research involving human embryonic stem cells (hESC) was first brought to the US court system, and despite some tense moments, including a temporary ban on National Institutes of Health (NIH) funding for hESC research, the courts have continued to uphold the legality of such…
Like songbirds and humans, male mice have brain circuits and behaviors they may use to learn some of their sounds.
Two U.S. scientists shared the Nobel Prize for Chemistry for learning how cells respond to the world around them, a finding that underpins many prescription drugs on the market today, from beta blockers and antihistamines to various kinds of psychiatric medications. Brian Kobilka, 57, of Stanford University Medical School, and 69-year-old Robert Lefkowitz, of the…
John B. Gurdon of the U.K. and Shinya Yamanaka of Japan shared this year’s Nobel Prize in Physiology or Medicine for their work in so-called cellular reprogramming, which has unleashed a wave of advances in everything from cloning to the possible treatment of diseases using stem cells. The researchers’ experiments showed how specialized, mature cells…
Washington State University researchers have found that the great-grandchildren of pregnant rats exposed to low doses of dioxin develop diseases and reproductive abnormalities — even though they did not have direct exposure. The finding challenges the traditional explanation of how traits are passed from one generation to another.
