A new digital ecology is evolving, and humans are being left behind

Incomprehensible computer behaviors have evolved out of high-frequency stock trading, and humans aren't sure why. Eventually, it could start affecting high-tech warfare, too. We spoke with a researcher at University of Miami who thinks humans will be outpaced by a new "machine ecology." » 9/11/13 10:28am 9/11/13 10:28am

Is your brain actually running a computer algorithm while you sleep?

It's no surprise that computers function a little bit like human minds — after all, humans built them using ourselves as models. But recent research into neural networks suggests that there is an uncanny connection between computer learning algorithms, and what your brain does when you're asleep. » 7/25/13 12:26pm 7/25/13 12:26pm
