What if the next gadget for sending messages to your friends wasn’t a watch strapped to your wrist or a phone stuffed in your pocket—but an electronic device embedded in your brain? Now, a new kind of flexible circuit has brought us one step closer to this science fiction future. Implanted via injection, a grid of wires only a few millimeters across can insinuate itself with living neurons and eavesdrop on their chatter, offering a way for electronics to interface with your brain activity.
When you bring home the wrong color of paint from the hardware store, it may not be your foggy memory at fault. A new study finds that while the human brain can distinguish between millions of colors, it has difficulty remembering specific shades.
According to new research, the fastest learners follow an old adage—”Don’t overthink it.” In a new study that analyzed brain activity of subjects while they tried to master a new task, scientists found the people who got it most quickly were the ones who shut off their higher-order, analytical cognitive processes.

And yet your brain — a nonstop multitasking marvel — runs on only about 20 watts of energy, the same wattage as an energy-saving light bulb.
