Deer proliferation disrupts a forest's natural growth Posted: 08 Mar 2014 06:55 AM PST Researchers have discovered that a burgeoning deer population forever alters the progression of a forest's natural future by creating environmental havoc in the soil and disrupting the soil's natural seed banks.

Establishing standards where none exist; researchers define 'good' stem cells Posted: 06 Mar 2014 10:04 AM PST A set of 64 crucial parameters has been identified by researchers from more than 1,000 by which to judge stem cell-derived cardiac myocytes, making it possible, for perhaps the first time, for scientists and pharmaceutical companies to quantitatively judge and compare the value of the countless commercially available lines of stem cells.

Sickle cell trait: Neglected opportunities in the era of genomic medicine Posted: 06 Mar 2014 08:22 AM PST While acknowledging the potential of genomics to prevent and treat disease, researchers believe it is long past due to use current scientific data and technical advances to reduce the burden of sickle cell disease, one of the most common serious single gene disorders. According to the researchers, few individuals of child-bearing age born in the United States know their SCT status.

'Most complete' picture of gene expression in cancer cell cycle caught Posted: 06 Mar 2014 07:39 AM PST Uncontrolled cell growth and division is a hallmark of cancer. Now a research project has provided the most complete description to date of the gene activity that takes place as human cells divide. Researchers have managed to gather data which details the behavior of protein molecules encoded by over 6000 genes in cancer cells, as they move through the cell cycle. The team has used advances in technology and data analysis to study how genes work over time in cancer cells, as opposed to capturing a `snapshot' of activity -- a leap forward they describe as akin to `jumping from still photography to video'.

Mental health care model reduced symptoms in those most affected by BP oil spill Posted: 06 Mar 2014 06:55 AM PST A model of care to provide mental health services after the Deepwater Horizon Gulf Oil Spill reduced both mental health and general medical symptoms in people affected by the tragedy. The novel approach embedded psychiatrists, psychologists, social workers and telemedicine resources into primary care clinics in the most affected areas.
