Quality of waking hours determines ease of falling sleep Posted: 17 Jun 2013 02:31 PM PDT The quality of wakefulness affects how quickly a mammal falls asleep, researchers report in a study that identifies two proteins never before linked to alertness and sleep-wake balance.

Study finds the sweet spot -- and the screw-ups -- that make or break environmental collective actions Posted: 17 Jun 2013 01:08 PM PDT Sustainability programs are a Goldilocks proposition -- some groups are too big, some are too small, and the environment benefits when the size of a group of people working to save it is just right. Scientists have found a sweet spot -- a group size at which the action is most effective. More importantly, the work revealed how behaviors of group members can pull bad policy up or drag good policy down.

Improving overall employee wellness could yield multiple benefits Posted: 17 Jun 2013 01:07 PM PDT Controlling health care costs is crucial for manufacturers to remain competitive. That's why researchers are working with manufacturers to determine if employee wellness programs will cut costs and improve productivity.

Testosterone improves verbal learning and memory in postmenopausal women Posted: 17 Jun 2013 11:20 AM PDT Postmenopausal women had better improvement in verbal learning and memory after receiving treatment with testosterone gel, compared with women who received sham treatment with a placebo, a new study found.

Chemical in antibacterial soap fed to nursing rats harms offspring, study finds Posted: 17 Jun 2013 09:21 AM PDT A mother's exposure to triclocarban, a common antibacterial chemical, while nursing her babies shortens the life of her female offspring, a new study in rats finds.

Prenatal exposure to BPA affects fat tissues in sheep Posted: 17 Jun 2013 09:21 AM PDT New research suggests that fetal exposure to the common environmental chemical bisphenol A, or BPA, causes increased inflammation in fat tissues after birth, which can lead to obesity and metabolic syndrome.

Planes, trains, or automobiles: Travel choices for a smaller carbon footprint Posted: 17 Jun 2013 08:13 AM PDT Planes, trains, or automobiles: what's the most climate-friendly way to travel? A new study by researchers from IIASA and CICERO brings better estimates of how much personal travel impacts the climate.

Too little sleep may trigger the 'munchies' by raising levels of an appetite-controlling molecule Posted: 17 Jun 2013 08:09 AM PDT Insufficient sleep may contribute to weight gain and obesity by raising levels of a substance in the body that is a natural appetite stimulant, a new study finds.

Excessive salt consumption appears to be bad for your bones Posted: 17 Jun 2013 08:09 AM PDT A high-salt diet raises a woman's risk of breaking a bone after menopause, no matter what her bone density is, according to a new study.

Adolescents' high-fat diet impairs memory and learning Posted: 17 Jun 2013 08:08 AM PDT A high-fat diet in adolescence appears to have long-lasting effects on learning and memory during adulthood, a new study in mice finds.

Babies seeing violence show aggression later Posted: 17 Jun 2013 08:07 AM PDT Aggression in school-age children may have its origins in children 3 years old and younger who witnessed violence between their mothers and partners, according to a new study.

Healthy, full-term babies use a different stress hormone than their mother Posted: 17 Jun 2013 07:46 AM PDT New research has identified how a steroid hormone may indicate infant distress during labor and delivery. The study suggests that a full-term, healthy baby preferentially secretes a different stress hormone than its mother does.

Sibling aggression linked to poor mental health Posted: 17 Jun 2013 06:11 AM PDT Fights between siblings are so common they're often dismissed as simply part of growing up.
