A molecular chink in the armor of tuberculosis
...m that causes tuberculosis (TB), has inadvertently tipped
off researchers to a potential chink in its armor. Researchers from the Howard Hughes Medical Institute (HHMI) have identified a lipid molecule that must be produced by M. tuberculosis if the bacterium is to infect the lungs of mice. "The unique l...

Chemical gradient steers nerve growth in spinal cord
...neurons in search of other nerve cells. Axons are tipped
with growth cones that can detect extracellular signals, such as Wnt4, and then grow toward or away from the source. The axon's journey from the cell body of a commissural neuron, found at the back of the spinal cord, up to the brain is a long and co...
