Scientists identify cells for spinal-cord repair Jul 23, 2008 Coronal sections of injured adult spinal cord, anterior to posterior. The labelling shows recombined ependymal cells and their progeny (white) migrating out to the injury area in the dorsal funiculus, as a reponse to the ...

Researchers offer glimpse of rare mutant cells Jul 22, 2008 MIT engineers used a new imaging technique to pinpoint the locations of mouse pancreatic cells with a specific mutation. The blue dots represent pancreatic cell nuclei, and the cells within the yellow cluster express the ...

'Snow flea antifreeze protein' could help improve organ preservation Jul 21, 2008 By creating an antifreeze protein found in the Canadian snow flea, scientists are reporting a development that could extend the storage life of donor organs. The figure shows representations of the unprecedented structure ...

Glia guide brain development in worms Jul 14, 2008 Mind-blowing. In C. elegans, fluorescent images show that when brain cells called glia are zapped — and killed — with a microscopic laser, neurons (red) survive but are highly abnormal (right) compared to normal ones (left).
