Scientists use stem cells to regrow spinal cords

Research on rats could one day help paralyzed humans 29.03.2016 By Barry Eitel SAN FRANCISCO Scientists announced Tuesday that they have successfully regenerated the spinal cords of paralyzed rats using stem cells, a breakthrough that the researchers hope will lead to human trials. Researchers built tiny patches of stem cells collected from rats and humans. They

Nanospheres shield chemo drugs, safely release high doses in response to tumor secretions

July 14, 2015-Nanowerk News-Scientists have designed nanoparticles that release drugs in the presence of a class of proteins that enable cancers to metastasize. That is, they have engineered a drug delivery system so that the very enzymes that make cancers dangerous could instead guide their destruction. "We can start with a small molecule and build
