Brain Protein "Rescues" Neurons From Atrophy
...or the first time, allows researchers to determine precisely which cells received the substance. The technique involved first coating minute fluorescent latex particles with the neurotrophins. The scientists then injected the neurotrophin-soaked beads into the ferrets' visual cortexes. The beads were taken up ...Heat-loving Microbe Repairs Its DNA With Light
... cells with UVradiation, whose effects on DNA are precisely known. As expected,the vast majority of cells were unable to reproduce followingthis treatment. If the cells were then exposed to visible light, however, asignificant fraction of the damaged cells revived.
