Research collaborative unveils novel biomarker linked to stress, resilience

Concerned about the effect of stress on your health and well-being? If your answer is "yes," then Arizona State University Professor Doug Granger is doing research that could impact you. Granger is pioneering the field of interdisciplinary salivary bioscience using spit.

Eye contact may make people more resistant to persuasion

Making eye contact has long been considered an effective way of drawing a listener in and bringing him or her around to your point of view. But new research shows that eye contact may actually make people more resistant to persuasion, especially when they already disagree. The new findings are published in Psychological Science, a journal of the Association for Psychological Science.

Making eye contact doesn't always help your cause

New research shows that making eye contact, long considered an effective way of bringing someone to your point of view, may actually make people more resistant to persuasion, especially when they already disagree.

"There is a lot of cultural lore about the power of eye contact as an influence tool," says University of British Columbia Prof. Frances Chen, who conducted the research at the University of Freiburg in Germany. "But our findings show that direct eye contact makes skeptical listeners less likely to change their minds, not more, as previously believed."

Decoding sound's source: Mass. Eye and Ear researchers unravel part of the mystery

BOSTON (Oct. 1, 2013) — As Baby Boomers age, many experience difficulty in hearing and understanding conversations in noisy environments such as restaurants. People who are hearing-impaired and who wear hearing aids or cochlear implants are even more severely impacted. Researchers know that the ability to locate the source of a sound with ease is vital to hear well in these types of situations, but much more information is needed to understand how hearing works to be able to design devices that work better in noisy environment.

Smoking during pregnancy may increase risk of bipolar disorder in offspring

A study published today in the American Journal of Psychiatry suggests an association between smoking during pregnancy and increased risk for developing bipolar disorder (BD) in adult children.

New research reveals that oxytocin could make us more accepting of others

(New York, New York) October 1, 2013 - Oxytocin - often referred to as the 'love hormone' because of its ability to promote mother-infant attachment and romantic bonding in adults - could also make us more accepting of other people, as found in new research carried out by Neuropsychoanalysis Foundation research grantee Valentina Colonnello Ph.D. and published online in Psychoneuroendocrinology.

Notre Dame study: The face is the focus for a person wielding a gun

A person wielding a gun focuses more intently on the face of an opponent with a gun, presumably to try to determine that person's likelihood of pulling the trigger, according to a new study that builds on gun-in-hand research from the University of Notre Dame.

Bad luck? Knocking on wood can undo jinx: study

Knocking on wood is the most common superstition in Western culture used to reverse bad fortune or undo a "jinx." Other cultures maintain similar practices, like spitting or throwing salt, after someone has tempted fate. Even people who aren't particularly superstitious often participate in these practices.

A new study from the University of Chicago Booth School of Business finds that these superstitions actually do "reverse" perceived bad fortune.

Tests in mice identify compound that may keep survivors of brain aneurysms from succumbing to stroke

Johns Hopkins researchers, working with mice, say they have identified a chemical compound that reduces the risk of dangerous, potentially stroke-causing blood vessel spasms that often occur after the rupture of a bulging vessel in the brain.

They say their findings offer clues about the biological mechanisms that cause vasospasm, or constriction of blood vessels that reduces oxygen flow to the brain, as well as potential means of treating the serious condition in humans.

Telestroke service increases rates of 'clot-buster' treatment for stroke, reports Neurosurgery

Philadelphia, Pa. (October 1, 2013) – A telestroke service increases the rate of effective tissue plasminogen activator (tPA) therapy for patients with acute ischemic stroke treated at community hospitals, according to a report in the October issue of Neurosurgery, official journal of the Congress of Neurological SurgeonsCongress of Neurological Surgeons.

Statin medications may prevent dementia and memory loss with longer use

A review of dozens of studies on the use of statin medications to prevent heart attacks shows that the commonly prescribed drugs pose no threat to short-term memory, and that they may even protect against dementia when taken for more than one year. The Johns Hopkins researchers who conducted the systematic review say the results should offer more clarity and reassurance to patients and the doctors who prescribe the statin medications.

How to stay sharp in retirement

Montreal, October 1, 2013 – October is Canada's Healthy Workplace Month, but how does one stay mentally fit after the 40-hour workweek is traded in for the gold watch?

The more you want to use your brain — and the more you enjoy doing it — the more likely you are to stay sharp as you age. This is according to findings recently published in the Journals of Gerontology: Psychological Sciences by a team of Concordia University researchers.

The new study has three major findings that can help forecast cognitive ability in one's golden years:

UT Dallas researchers find early success in new treatment for stroke recovery

Researchers at The University of Texas at Dallas have taken a step toward developing a new treatment to aid the recovery of limb function after strokes.

In a study published online in the journal Neurobiology of Disease, researchers report the full recovery of forelimb strength in animals receiving vagus nerve stimulation.

ForWarn follows rapidly changing forest conditions

U.S. Forest Service and partner scientists are keeping a watchful eye on forest health. As fall colors replace the lush greenness of spring and summer, researchers recognize telltale signs of change in healthy forests.

A new publication highlights specific examples where researchers have used ForWarn, a state-of-the-art forest change recognition and tracking system, to detect disturbances and track forest recovery. ForWarn uses NASA satellite imagery to develop real-time maps that assist forest managers in the continental United States.

Clinician observations of preschoolers' behavior help to predict ADHD at school age

Don't rely on one source of information about your preschoolers' inattention or hyperactivity. Rather, consider how your child behaves at home as well as information from his or her teacher and a clinician. This advice comes from Sarah O'Neill, of The City College of New York, based on research she conducted at Queens College (CUNY), in an article published in Springer's Journal of Abnormal Child Psychology.
