Researchers generate human-monkey chimeric embryos

Investigators in China and the United States have injected human stem cells into primate embryos and were able to grow chimeric embryos for a significant period of time—up to 20 days. The research, despite its ethical concerns, ...

Study finds evidence for existence of elusive 'metabolon'

For more than 40 years, scientists have hypothesized the existence of enzyme clusters, or "metabolons," in facilitating various processes within cells. Using a novel imaging technology combined with mass spectrometry, researchers ...

An enzyme to ease biofuel production

Limited availability of fossil fuels stimulates the search for different energy resources. The use of biofuels is one of the alternatives. Sugars derived from the grain of agricultural crops can be used to produce biofuel ...

Chimpanzee 'mini-brains' hint at secrets of human evolution

At some point during human evolution, a handful of genetic changes triggered a dramatic threefold expansion of the brain's neocortex, the wrinkly outermost layer of brain tissue responsible for everything from language to ...

Chemists engineer plants to produce new compounds

(PhysOrg.com) -- In work that could expand the frontiers of genetic engineering, MIT chemists have, for the first time, genetically altered a plant to produce entirely new compounds, some of which could be used as drugs against ...
