Efforts to connect human brains to computers have taken big leaps forward in recent years. Melding our minds with machines could provide the biggest single upgrade to human intelligence since our species evolved. But are we ready?

“Within five years, I have no doubt there will be robots in every Army formation.”
From the spears hurled by Romans to the missiles launched by fighter pilots, the weapons humans use to kill each other have always been subject to improvement. Militaries seek to make each one ever-more lethal and, in doing so, better protect the soldier who wields it. But in the next evolution of combat, the U.S. Army is heading down a path that may lead humans off the battlefield entirely.
Over the next few years, the Pentagon is poised to spend almost $1 billion for a range of robots designed to complement combat troops. Beyond scouting and explosives disposal, these new machines will sniff out hazardous chemicals or other agents, perform complex reconnaissance and even carry a soldier’s gear.

Cornell University engineers have designed a revolutionary 3D lithium-ion battery that could be charged in just seconds.
In a conventional battery, the battery’s anode and cathode (the two sides of a battery connection) are stacked in separate columns (the black and red columns in the left illustration above). For the new design, the engineers instead used thousands of nanoscale (ultra-tiny) anodes and cathodes (shown in the illustration on the right above).
