Scientists Grow Human Brain Tissue from Stem Cells

Scientists said Wednesday they had used stem cells to grow primitive human brain tissue for use in studying disorders and early development of this most complex of organs.

They used the cells to grow what they dubbed "cerebral organoids" -- pea-sized blobs of 3D brain tissue in a Petri dish, with characteristics of early embryonic brain tissue.

Study: China to Add 1,500 Gigawatts of Power Capacity by 2030

China will add some 1,500 gigawatts of power production capacity by 2030, or the equivalent of Britain's existing capacity every year, a study showed on Wednesday.

Although the world's biggest carbon emitter will continue to draw considerable capacity from coal-fired plants, about half of the new capacity will be generated from renewable sources, Bloomberg New Energy Finance (BNEF) said in its report.
