Details of calcium 'safety-valve' in cells explained Posted: 06 Jun 2014 03:54 PM PDT The atomic level structure of a protein that regulates the level of calcium in cells has been detailed by scientists, providing clues about a key signaling agent that can trigger programmed cell death and potentially leading to new anticancer drug targets.

Argument with dad? Find friendly ears to talk it out, study shows Posted: 06 Jun 2014 03:54 PM PDT Adolescents' well-being can improve when conflicts with their father are adequately explained -- by mom, a friend or even dad himself. Adolescents who receive an reason for the father's behavior or a better understanding of who is at fault feel better about themselves and about dad as well. Those feelings about dad, in turn, are linked to a lower risk of depression for youth.

Better tissue healing with disappearing hydrogels Posted: 06 Jun 2014 03:49 PM PDT When stem cells are used to regenerate bone tissue, many wind up migrating away from the repair site, which disrupts the healing process. But a research team makes use of a technique that keeps the stem cells in place, resulting in faster and better tissue regeneration.

Brain traffic jams that can disappear in 30 seconds Posted: 06 Jun 2014 03:48 PM PDT Motorists in Los Angeles, San Francisco and other gridlocked cities could learn something from the fruit fly. Scientists have found that cellular blockages, the molecular equivalent to traffic jams, in nerve cells of the insect's brain can form and dissolve in 30 seconds or less.

Vitamin D and the nursing mother Posted: 06 Jun 2014 03:48 PM PDT The not-often-discussed issue of Vitamin D deficiency in nursing mothers is discussed by an expert, and how it can affect the infants in their care. An "adequate" intake for nursing mothers is not the 400 IU/d the IOM recommends, but is instead in the range of 5,000-6,000 IU/d, taken daily. If they get that much, they will meet not only their own needs, but their infant's as well.
