Shai Shaham and Sean Brady receive promotions
Shaham, head of the Laboratory of Developmental Genetics, studies the control of programmed cell death during animal development and the roles of glial cells in nervous system development and function. He has been awarded tenure and promoted to professor. Brady, head of the Laboratory of Genetically Encoded Small Molecules, looks for new genetically encoded small molecules from bacterial sources, chemicals that may play a role in the development of new pharmaceuticals. He has been promoted to associate professor.

Scientists show how a neuron gets its shape
For the brain to work, neurons have to be connected in the right places. Now, new research shows that rather than growing like the branches of a tree — extending outward — certain neurons work backward from their destination, dropping anchor and stretching their dendrites behind them as they crawl away.

Without glial cells, animals lose their senses
When it comes to picking up and bringing information into the brain, sensory neurons have always put on a star performance. But now they’ll need to share the credit. In groundbreaking research to appear in the October 31 issue of Science, scientists reveal that while neurons play the lead role, a second type of cell, the glial cell, pulls the strings behind the scenes. The work not only lifts a long-ignored cell out from obscurity but shows how it is a critical member in shaping sensory experience. More »

Glia guide brain development in worms
When the stakes are high, communication is crucial. In a landmark discovery, Rockefeller University scientists have identified a system in the C. elegans brain that allows them to study how brain cells, neurons and glia, talk to each other — the dialogue that shapes and guides the developing brain.

New method exploits old mechanism to turn genes on and off at will
When body heat rises to dangerously high temperatures, the heat shock response protects proteins from irreversible damage. Now, new research in C. elegans roundworms exploits this ancient mechanism to control when and where genes are expressed, an ability that helps determine which cells require the expression of certain genes during different stages of development. While existing techniques enabled scientists to achieve this feat, this new method provides them with the same information in a fraction of the time. More »

For dying cells, timing is everything
Conventional wisdom suggests that cells are at all times balanced precariously between life and death, with proteins that could kill the cell poised to strike at a moment’s notice. While this is certainly true in some cases, new research from Rockefeller University shows that it is not universal, and that several layers of regulation control cell death. More »
Researcher discover new cell death program
Though caspases are the accepted executioners of the cell world, new research shows that they may not be the only ones. By following the life, and death, of one cell, Rockefeller University researchers discover a new type of cell death. More »
