Proteins in histone group might influence cancer development, study shows Posted: 03 Sep 2013 04:42 PM PDT Spool-like proteins called histones play a crucial role in packaging the nearly seven feet of DNA found in most human cells. It has been thought that a particular group of histone isoforms were functionally identical. This study shows that these isoforms can have distinct functions, and that they might play a role in cancer development. The results provide a new mechanism for the regulation of chromatin structure.

Why parenting can never have a rule book: Children's genetics significantly affect how they are parented Posted: 03 Sep 2013 04:41 PM PDT Any parent will tell you that there is no simple recipe for raising a child. Being a parent means getting hefty doses of advice -- often unsolicited -- from others. But such advice often fails to consider a critical factor: The child. A new review of dozens of studies involving more than 14,600 pairs of twins shows that children's genetics significantly affect how they are parented.

Brain wiring quiets the voice inside your head Posted: 03 Sep 2013 04:40 PM PDT Researchers have developed the first diagram of the brain circuitry that enables a complex interplay between the motor system and the auditory system to occur.

Lessons from the worm: How the elderly can live an active life Posted: 03 Sep 2013 09:30 AM PDT When the tiny roundworm C. elegans reaches middle age —- at about 2 weeks old -— it can't quite move like it did in the bloom of youth. But rather than imposing an exercise regimen to rebuild the worm's body-wall muscles, researchers can bring the wriggle back by stimulating the animal's neurons. And, they say, pharmaceuticals might have a similar effect in mammals.

Aging really is 'in your head:' Scientists answer hotly debated questions about how calorie restriction delays aging process Posted: 03 Sep 2013 09:30 AM PDT Among scientists, the role of proteins called sirtuins in enhancing longevity has been hotly debated, driven by contradictory results from many different scientists.
