Contrary to prevailing wisdom, a new study from plant biologists at UC Davis shows that proteins of the Hsp70 family do indeed chaperone proteins across the membranes of chloroplasts, just as they do for other cellular structures.

DURHAM, N.C. – As good as laparoscopy is in preventing some of the stresses of open surgery on the body, it does have drawbacks, including reduced blood flow and organ dysfunction. Laparoscopy is a type of surgery in the abdomen done through small incisions.

The work provides insight into potential therapeutic for cancer and eye diseases
LA JOLLA, CA—December 10, 2009—Researchers at The Scripps Research Institute have solved a 10-year-old mystery of how a single protein from an ancient family of enzymes can have two completely distinct roles in the body. In addition to providing guidance for understanding other molecules [...]

What’s black and white and read all over? The giant panda genome. All 2.4 billion DNA base pairs of a 3-year-old female panda named Jingjing have been cataloged, researchers report online December 13 in Nature. The information will help researchers understand panda traits such as finicky diets. A thorough understanding of panda genetics may aid [...]

A new formulation of the vitamin E extract tocotrienol could play a key role in treating cancerous tumors without harming healthy tissue. Tocotrienol has anti-cancer properties, but when given intravenously it has secondary effects on healthy tissue; now researchers in the UK have found that delivering the compound encapsulated in transferrin-bearing vesicles can shrink tumors [...]

Neurologists in the US suggest irregular arm swings while walking could be an early sign of Parkinson’s disease and scientific measurement of such a suspected symptom could help diagnose the disease earlier, giving greater opportunity to slow brain cell damage and disease progression.
