Easter Island drug raises cognition throughout life span in mice Posted: 29 Jun 2012 06:19 PM PDT Rapamycin, a compound first isolated from soil on Easter Island, enhanced learning and memory in a study of young, middle-aged and older mice. The findings are from the School of Medicine and Barshop Institute at The University of Texas Health Science Center San Antonio.

New gene mutations that lead to enlarged brain size, cancer, autism, epilepsy identified Posted: 29 Jun 2012 06:18 PM PDT Scientist have discovered new gene mutations associated with markedly enlarged brain size, or megalencephaly.

Bees shed light on human sweet perception and metabolic disorders Posted: 29 Jun 2012 06:18 PM PDT Scientists have discovered that honey bees may teach us about basic connections between taste perception and metabolic disorders in humans. By experimenting with honey bee genetics, researchers have identified connections between sugar sensitivity, diabetic physiology and carbohydrate metabolism. Bees and humans may partially share these connections.

New properties of stem cells via simulated microgravity Posted: 29 Jun 2012 06:14 PM PDT A recent study set out to illustrate novel mechanical transduction properties of hematopoietic stem cells in relation to defining the expression of humoral factors by facilitating paracrine/autocrine signalling via microgravity.

'Ambient' bullying gives employees urge to quit Posted: 29 Jun 2012 11:25 AM PDT Merely showing up to work in an environment where bullying goes on is enough to make many of us think about quitting, a new study suggests.

Caffeine boosts power for elderly muscles Posted: 29 Jun 2012 09:04 AM PDT Caffeine boosts power in older muscles, suggesting the stimulant could aid elderly people to maintain their strength, reducing the incidence of falls and injuries, according to new research.

Unemployed Americans face greater risk of mortality Posted: 28 Jun 2012 10:10 AM PDT Employment policy is also health policy according to a new study that found that workers experienced higher mortality rates if they didn't have access to social protections like employment insurance and unemployment benefits.
