Scientists at the Salk Institute have discovered an on-and-off “switch” in cells that may hold the key to healthy aging. This switch points to a way to encourage healthy cells to keep dividing and generating, for example, new lung or liver tissue, even in old age. In our bodies, newly divided cells constantly replenish lungs, …

While LPPFusion’s research team expects to eliminate the major sources of electrode erosion, enough to get rid of significant impurities in the plasma, some erosion will still exist. It won’t be enough to bother us during the current experimental phase, but once they are engineering a generator that fires 200 times second, remaining erosion will …
India has 15000 tons of plastic waste every day. This amount should double in 5 years. 5,000 kilometers (3,000 miles) of plastic roads have been laid in India in at least 11 states. Solving India’s garbage problem requires more than a technological solution. In a country where throwing garbage onto the roads and littering in …
