In the brain, as in business, connections are everything. To maintain cellular associates, the outer surface of a neuron, its membrane, must express particular proteins—proverbial…
Researchers at the University of Wisconsin-Madison have discovered that a protein called Munc13-4 helps cancer cells secrete large numbers of exosomes–tiny, membrane-bound packages containing proteins…
Like an island nation, the nucleus of a cell has a transportation problem. Evolution has enclosed it with a double membrane, the nuclear envelope, which…
A new method for monitoring interactions between cells, dubbed LIPSTIC by its creators, is much more than a cosmetic improvement over existing techniques. The breakthrough,…
Using geometry, scientists from the Laboratory of Stem Cell Biology and Molecular Embryology at Rockefeller University have coaxed human embryonic stem cells to organize themselves….
Scientists from MIT, Rockefeller University and the Medical College of Wisconsin are hoping to better understand why an infectious disease like hepatitis C has different…
