Cotton candy machines may hold the key for making life-sized artificial livers, kidneys, bones and other essential organs, researchers say. For several years, Leon Bellan, assistant professor of mechanical engineering at Vanderbilt University, has been tinkering with cotton candy machines, getting them to spin out networks of tiny threads comparable in size, density and complexity… Continue reading Cotton Candy Machines and Artificial Organs

Stopping Aging via Remote Control
An anti-aging process that involves remote control of cells? It sounds like science fiction, but it’s getting closer to reality thanks to biologists from UCLA. The scientists, working with fruit flies, remotely increased levels of a gene called AMPK. The gene, a crucial sensor of energy in cells, gets activated when cellular energy levels are… Continue reading Stopping Aging via Remote Control
