Making memories stronger and more precise during aging

Making memories stronger and more precise during aging

When it comes to the billions of neurons in your brain, what you see at birth is what get -- except in the hippocampus. Buried deep underneath the folds of the cerebral cortex, neural stem cells in the hippocampus continue to generate new neurons, inciting a struggle between new and old as the new attempts to gain a foothold in memory-forming center of the brain.

Rotten egg gas could help protect diabetics from heart complications

A gas that was formerly known for its noxious qualities could help people with diabetes recover from common heart and blood vessel complications, concludes research led by the University of Exeter Medical School.

Parental psychiatric disease linked with elevated risks of attempted suicide and violent offending during adulthood

In the first study to consider these two adverse outcomes in the same cohort, researchers have shown a strong correlation between parental psychiatric disorder and the increased risk of suicide attempts and violent behaviour in their children.

When silencing phantom noises is a matter of science

With a clever approach, researchers point to the first gene that could be protective of tinnitus -- that disturbing ringing in the ear many of us hear, when no sound is present.

Strain differences in Zika infection gene patterns

Strain differences in Zika infection gene patterns

Scientists have revealed molecular differences between how the African and Asian strains of Zika virus infect neural progenitor cells.

The results could provide insights into the Zika virus' recent emergence as a global health emergency, and also point to inhibitors of the protein p53 as potential leads for drugs that could protect brain cells from cell death.

Parents' math skills 'rub off' on their children

PITTSBURGH--Parents who excel at math produce children who excel at math. This is according to a recently released University of Pittsburgh study, which shows a distinct transfer of math skills from parent to child. The study specifically explored intergenerational transmission--the concept of parental influence on an offspring's behavior or psychology--in mathematic capabilities.

Wounds from childhood bullying may persist into college years, study finds

Wounds from childhood bullying may persist into college years, study finds

CHAMPAIGN, Ill. -- Childhood bullying inflicts the same long-term psychological trauma on girls as severe physical or sexual abuse, suggests a new survey of college students.

The threat of group extinction proves a powerful motivator

Charles Darwin was right: Groups enjoy an advantage whose members are "ready to aid one another and to sacrifice themselves for the common good," according to a new study by researchers at Rice University, Texas A&M University and the University of East Anglia.

Using variations of the public goods game, the researchers showed that when no other mechanism is present to reinforce group cooperation, the threat of group extinction is sufficiently powerful to motivate and increase cooperation within a group.

Address systemic issues to change toxic health care environment, SLU commentary says

Address systemic issues to change toxic health care environment, SLU commentary says

ST. LOUIS - A multipronged approach that improved mental health among Saint Louis University students during their first year of medical school could serve as a model for reducing stress and depression later in their training, says the author of a commentary in the September issue of Academic Medicine.

"It's an antiquated idea that what doesn't kill you makes you stronger," Stuart Slavin, M.D., M.Ed., associate dean of curriculum for SLU School of Medicine, says. "For far too many in medical school it simply makes them burned out, anxious and depressed."

Want to hit your target? Good luck, short stuff

COLUMBUS, Ohio - Tall quarterbacks might have more going for them than a clear view over the offensive line.

New research shows that tall people are better than shorter people at correctly identifying the location of targets in their middle-distance vision - between three and 20 meters away. (In football, that would be about three to 22 yards away.)

And that visual superiority holds true even when tall people sit down and their shorter counterparts stand on a box or stool, found a first-of-its-kind study.
