Scientists have discovered genetic variants that are associated with biological aging, a finding that could explain why some people seem to age faster than others.

Biologists have identified plant enzymes that may help to engineer plants that take advantage of elevated carbon dioxide to use water more efficiently. The finding could help to engineer crops that take advantage of rising greenhouse gases.

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 in the family, the research supplies a theoretical underpinning for the protein’s possible use for combating diseases including cancer and macular degeneration.

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 conservation efforts for the endangered bear.

A new study involving data from more than 20,000 individuals has uncovered several DNA sequences linked to impaired pulmonary function. The research, an analysis that combined the results of several smaller studies, provides insight into the mechanisms involved in reaching full lung capacity. The findings may ultimately lead to better understanding of lung function and diseases like asthma and chronic obstructive pulmonary disease (COPD), the fourth leading cause of death in the United States.

Cells are not static. They can transform themselves over time — but change can have dangerous implications. Benign cells, for example, can suddenly change into cancerous ones.
