The objections surrounding the use of embryonic stem cells in organ and tissue reconstruction could be silenced if clinical trials for a new strain of stem cells derived from liposuctioned fat get a nod of approval from the FDA.

Over 150 years after Snow essentially founded modern epidemiology, a team of American scientists are using remote satellite imaging to predict cholera outbreaks before they occur.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
