Study highlights importance of mRNA translation in aging process

When researchers at the Buck Institute dialed back activity of a specific mRNA translation factor in adult nematode worms they saw an unexpected genome-wide response that effectively increased activity in specific stress response genes that could help explain why the worms lived 40 percent longer under this condition.

Neurochemical-producing probiotics can promote healthy gut and mind

Probiotics, often referred to as 'good bacteria', are known to promote a healthy gut, but can they promote a healthy mind? Exploring the new world of neurological probiotics, researchers in BioEssays present new ideas on how neurochemicals delivered directly to the gut, via probiotic intestinal microbiota, exert their beneficial effects in maintaining gastrointestinal health and even psychological well-being.

Johns Hopkins team reconstitutes single stem cells' family tree

A Johns Hopkins team has discovered in young adult mice that a lone brain stem cell is capable not only of replacing itself and giving rise to specialized neurons and glia - important types of brain cells - but also of taking a wholly unexpected path: generating two new brain stem cells.

Teens regardless of ethnic backgrounds retain religious identity

High school is a turbulent time for adolescents. Every parent knows these are the years when teens begin to spread their wings, develop their own self-awareness and confirm their identification with specific social groups and cultures. In short, they find their niche.

Scientists discover enzyme that can regulate breast cancer development

Researchers at Cold Spring Harbor Laboratory (CSHL) have identified an enzyme that appears to be a significant regulator of breast cancer development. Called PTPN23, the enzyme is a member of a family called protein tyrosine phosphatases, or PTPs, that plays a fundamental role in switching cell signaling on and off.

Research sheds light on well-documented 'other-race effect'

Northwestern University researchers have provided new biological evidence suggesting that the brain works differently when memorizing the face of a person from one's own race than when memorizing a face from another race.

Brain stem cells shown to generate multiple new brain stem cells

A Johns Hopkins team has discovered in young adult mice that a lone brain stem cell is capable not only of replacing itself and giving rise to specialized neurons and glia – important types of brain cells – but also of taking a wholly unexpected path: generating two new brain stem cells.

Early life adversity and prior depressive episodes make people become depressed more easily

We all know people who are able to roll with life's punches, while for others, every misfortune is a jab straight to the gut. Research examining this issue has found that although most people require significant adversity to become depressed - the death of a loved one, say, or getting fired - roughly 30 percent of people with first-time depression and 60 percent of people with a history of depression develop the disorder following relatively minor misfortunes.
