This lecture is the one primer you need on NSA surveillance technology

We know that the NSA has been monitoring millions of calls made in the United States. But what are they doing with that data? And how do they analyze it? Find out everything you need to know in this incredible lecture from Princeton computer science professor and government technology adviser Ed Felten. » 2/28/14 5:05pm 2/28/14 5:05pm

Watch the subversive version of spy tech conference RSA

Right now, downtown San Francisco is teeming with people attending RSA, the world's biggest conference devoted to "cybersecurity." But up the street, there's another tech conference. It's full of computer security analysts who want to stop the surveillance state. It's called Trustycon, and you can watch it here, live. » 2/27/14 9:20am 2/27/14 9:20am

Bots show how tough environments affect evolution

Animals come in sorts of shapes and sizes, but why they have to be so different from each other remains a mystery to evolutionary biologists. But a recent computer simulation suggests that body types remain simple when placed in simple environments, but evolve into complex shapes when things get challenging. » 1/03/14 8:40am 1/03/14 8:40am

​What will NASA be doing with its new quantum computer?

Earlier this year, NASA, in partnership with Google, acquired the world's largest quantum computer. But just what does the space agency plan to do with a device with such revolutionary potential? We talked to one of their lead researchers to find out. » 11/20/13 11:40am 11/20/13 11:40am

Quantum Computing Takes a Gigantic Leap Forward

An international team of scientists have just held a qubit's memory state for 39 minutes. That might not sound like much, but it's 100 times longer than the previous record. It's a groundbreaking achievement that could pave the way to freakishly fast computers. » 11/15/13 1:00pm 11/15/13 1:00pm

Ten Steps You Can Take Right Now Against Internet Surveillance

One of the trends we've seen is how, as the word of the NSA's spying has spread, more and more ordinary people want to know how (or if) they can defend themselves from surveillance online. But where to start? » 10/27/13 10:00am 10/27/13 10:00am

Breakthrough: The World’s First Carbon Nanotube Computer

It’s only got 178 transistors, but it’s an important proof-of-concept that’s poised to keep Moore’s Law right on track. The breakthrough, in which a basic computer was powered by microscopic chains of carbon atoms, means we may have finally found a viable alternative to silicon chips. » 9/25/13 12:00pm 9/25/13 12:00pm

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

We now have brain-to-brain interfaces that work between two humans

You may never become Xavier from the X-Men, able to read and control people's minds. But one day, using a computer interface, you could control somebody else's behavior and possibly even communicate using thought. The technology you see demonstrated in this video is the first step. » 8/29/13 11:07am 8/29/13 11:07am

A computer that can read letters directly from your brain

By using brain scan data and a set of computer algorithms, scientists from the Netherlands were able to determine which letters a person was looking at. The breakthrough suggests it'll soon be possible to reconstruct human thoughts at an unprecedented level of detail, including what we see, remember — and even dream. » 8/22/13 10:36am 8/22/13 10:36am

New Computer Programming Language Imitates The Human Brain

As we pointed out earlier this week, we’re still far from being able to replicate the awesome power of the human brain. So rather than use traditional models of computing, IBM has decided to design an entirely new computer architecture — one that’s taking inspiration from nature. » 8/09/13 3:21pm 8/09/13 3:21pm

This substance will let you turn your skin into a computer

Scientists have created "electronic foils" that will allow circuits to conform to any surface — or get stretched, bent, and crumpled. The electronics may someday become as common as plastic wrap, researchers say. » 7/25/13 3:59pm 7/25/13 3:59pm
