New approach to treating gastrointestinal disease patches up leaky intestines
Researchers have discovered a new compound that helps fortify the intestine's inner lining, which becomes porous in inflammatory bowel diseases.  
New tool allows scientists to catch elusive protein in action
Scientists still have a lot to learn about the processes that trigger cell division, partly because they happen so quickly. A new chemical probe will make it possible to capture the workings of one of the key players.
Researchers discover a common link among diverse cancer types
Some cancers have been traced to changes in histones, proteins responsible for packaging DNA and regulating genes. Now, research from Rockefeller scientists shows that, among tumors, mutations to these proteins are a lot more common than previously suspected.
Enzyme structure reveals how DNA is opened up for transcription
DNA’s two strands must be separated before its code can be read, or transcribed. By studying the structure of the enzyme RNA polymerase, researchers have elucidated how DNA unwinds and becomes legible.
Study explains how geckos gracefully gallop on water
Geckos are amazingly agile. In addition to running across land and up trees, the animals can prance across the surface of water. A new study reveals how they do it.
Shape-shifting protein protects bacteria from invaders
Researchers have discovered how bacteria manage to destroy enemy DNA, while keeping their own genetic material safe.
First mapping of cells in the early human placenta to advance research on problem pregnancies
Scientists have made the first comprehensive inventory of cells present in the human placenta of the first trimester, a stage when many pregnancy complications are thought to arise. The findings could fuel new research on conditions such as preeclampsia and pre-term birth.
Enzyme structure helps to explain how protein factories are constructed
Researchers characterized the structure of Mdn1, an enzyme key to making ribosomes.
Sohail Tavazoie promoted to professor
Sohail Tavazoie, a physician-scientist who studies the genes that regulate a tumor’s ability to metastasize, has been promoted to professor.
Structural studies help explain how cancer cells resist chemotherapy
New research sheds light on how some cancer cells use molecular pumps to expel chemotherapy drugs before they have a chance to work.
