The International Institute for Species Exploration at Arizona State University and an international committee of taxonomists – scientists responsible for species exploration and classification – today announce the top 10 new species described in 2007.

Diabetes researchers at the John G. Rangos Sr. Research Center at Children’s Hospital of Pittsburgh of UPMC have identified a potential target for the development of new therapies to treat hypertriglyceridemia, a lipid disorder commonly seen in people who are obese and diabetic. Results of their study are published in the June issue of the Journal of Clinical Investigation.

Sea buckthorn (Hippophae rhamnoides) berries are well known for their cholesterol busting properties, but scientists in India say that its leaves are also rich in anti-oxidants and may help ward off liver disease, according to new research due to be published in the Society of Chemical Industry’s (SCI) Journal of the Science of Food and Agriculture.
