Discarded data may hold the key to a sharper view of molecules
There's nothing like a new pair of eyeglasses to bring fine details into sharp relief. For scientists who study the large molecules of life from proteins to DNA, the equivalent of new lenses have come in the form of an advanced method for analyzing data from X-ray crystallography experiments.

Researchers identify protein necessary for behavioral flexibility
Researchers have identified a protein necessary to maintain behavioral flexibility, which allows us to modify our behaviors to adjust to circumstances that are similar, but not identical, to previous experiences. Their findings, which appear in the journal Cell Reports, may offer new insights into addressing autism and schizophrenia—afflictions marked by impaired behavioral flexibility.

Scientists discover enzyme that could slow part of the aging process in astronauts -- and the elderly
New research published online in the FASEB Journal suggests that a specific enzyme, called 5-lipoxygenase, plays a key role in cell death induced by microgravity environments, and that inhibiting this enzyme will likely help prevent or lessen the severity of immune problems in astronauts caused by spaceflight. Additionally, since space conditions initiate health problems that mimic the agi

Scientists find the structure of a key 'gene silencer' protein
Scientists at The Scripps Research Institute have determined the three-dimensional atomic structure of a human protein that is centrally involved in regulating the activities of cells. Knowing the precise structure of this protein paves the way for scientists to understand a process known as RNA-silencing and to harness it to treat diseases.

Small molecular bodyguards kill HPV-infected cancer cells by protecting tumor-suppressor
Researchers at The Wistar Institute announce the discovery of small molecules that kill cancer cells caused by infection with human papillomavirus (HPV). Their results, in both cell and mouse models, demonstrate that the small molecule inhibitors protect a tumor-suppressing protein targeted by viral proteins, thus killing the infected tumor cells.
