New stain may work where others don't

Researchers observe a new mechanism by which receptors enter hippocampal neurons

data that's essential for mathematical modeling of biological pathways.

A new tissue-engineering method tricks the body into growing its own bone grafts.

Researchers at Stanford University have miniaturized the chemostat, a device widely used as a steady culture environment for bacterial cultures.1 Using only 16 nanoliters of culture media (nearly 109 less volume than conventional chemostats), the "microchemostat" avoids the problem of biofilm, which grows on chemostat walls and ultimately leaks into the culture media, causing contamination.The group worked out a cleaning scheme in which one of the device's six independent reactors is closed off

Without a sufficient cell culture system, researchers have had little success designing and testing drugs for the treatment of the hepatitis C virus (HCV).

Researchers have spent decades determining how proteins interact with each other in complex signaling networks by studying these relationships one at a time in isolation.

© 2005 Center for Development BiologyResearchers at the University of Utah are among the first to use large-scale genetics to study the planarian Schmidtea mediterranea, which contains a genome thought to contain insight into adult stem cell pluripotency and tissue regeneration.1Because the organism does not reproduce sexually, it cannot be studied using traditional genetic techniques. But by using bacterial-fed RNA interference against 1065 planarian genes, the study "effectively makes an
