Children's Hospital scientists achieve repair of injured heart muscle in lab tests of stem cells
Researchers at Children's Hospital of Pittsburgh of UPMC have been able to effectively repair damaged heart muscle in an animal model using a novel population of stem cells they discovered that is derived from human skeletal muscle tissue.   view more (2008-11-26)

NC State study shows bird population estimates are flawed
Most of what we know about bird populations stems from surveys conducted by professional biologists and amateur birdwatchers, but new research from North Carolina State University shows that the data from those surveys may be seriously flawed - and proposes possible means to resolve the problem.   view more (2008-11-21)

Antibiotics Can Cause Pervasive, Persistent Changes to the Microbial Community in the Human Gut, MBL and Stanford Scientists Report
Using a novel technique developed by Mitchell Sogin of the Marine Biological Laboratory (MBL) to identify different types of bacteria, scientists have completed the most precise survey to date of how microbial communities in the human gut respond to antibiotic treatment.   view more (2008-11-19)

Overfishing threatens European bluefin tuna
Bluefin tuna disappeared from Danish waters in the 1960s. Now the species could become depleted throughout the northeast Atlantic and Mediterranean, according to analyses by the Technical University of Denmark (DTU Aqua) and University of New Hampshire. The species is highly valued as sushi.   view more (2008-11-07)

In a last 'stronghold' for endangered chimpanzees, survey finds drastic decline
In a population survey of West African chimpanzees living in Côte d'Ivoire, researchers estimate that this endangered subspecies has dropped in numbers by a whopping 90 percent since the last survey was conducted 18 years ago.   view more (2008-10-14)

A link between mitochondria and tumor formation in stem cells
Researchers report on a previously unknown relationship between stem cell potency and the metabolic rate of their mitochondria -a cell's energy makers. Stem cells with more active mitochondria also have a greater capacity to differentiate and are more likely to form tumors.   view more (2008-10-13)
