A lot of the debate about when modern humans became modern humans has to do with the head--when our brains evolved into the functional equivalent of that of modern mankind. But while that particular argument continues, a team of UK researchers using a new kind of statistical technique have analyzed ancient footprints at a site in Tanzania and found that if our feet are allowed to tell the tale, our early ancestors were becoming human-like as much as two million years earlier than we previously thought.

The military garb designed by mechanical engineer Homayoon Kazerooni at the University of California, Berkeley, is anything but standard issue. Kazerooni’s 90-pound battlesuit, dubbed BLEEX for Berkeley Lower Extremity Exoskeleton, consists of a pair of robotic legs and backpack-like frame. Wearing the prototype, a soldier can haul up to 75 extra pounds with little effort. BLEEX is still a far cry from the superhuman combat gear envisioned by the Defense Advanced Research Projects Agency, which is funding the research.
