New study finds genetically engineered crops could play a role in sustainable agriculture

...to human health and biodiversity, but few analyses exist that reveal the actual effects genetically modified plants have on other non-modified species. In an analysis of 42 field experiments, scientists found that this particular modification, which causes the plant to produce an insecticide internally, c...

New collaborative research reveals chimpanzees can sustain multiple-tradition cultures

...ltiple-tradition cultures many researchers believe exist in the wild, providing further evidence chimpanzees and humans shared a common ancestor five to six million years ago who had a similar level of cultural complexity. For years, primatologists have suggested different communities of chimpanzees acr...

They also found that, just as embryonic cells have been shown to do, these adult stem cells produced both C-peptide, a part of the insulin precursor protein, and insulin itself. Confirming the presence of the C-peptide was es...
