Newborn brains grow vision and movement regions first

...e findings are intriguing, Gilmore said, they just scratch the surface of an area that has been little studied so far and in which much more research needs to be done. "This study gives us the first glimpse that there are regional differences in how quickly the brain is growing, and these regional differen...

Researchers create artificial enzyme that mimics the body's internal engine

...rate sequence of 32 chemical steps, was built from scratch and took several years to develop. The site contains the three active centers found in the naturally occurring enzyme: an organic molecule called phenol, an iron atom and a copper atom. Working together, these three centers provide the four electr...
