FEAST YOUR EYES ON THIS

Sean Andrist, a PhD student at the University of Wisconsin-Madison, has been researching social gaze with robots. He’s developed algorithms that help robots look at people at the right times and in the right ways. It’s not just making the robots less creepy, but more helpful as well.
THERE'S MOORE TO COME

Today’s technology makes a 1-exaflop supercomputer capable of performing 1 million trillion floating-point operations per second almost inevitable. But pushing supercomputing beyond that point to 10 exaflops or more will require major changes in both computing technologies and computer architectures.

The most organic and eco-friendly way of dealing with weeds is the old-fashioned way: physically removing them. And the best way to do that might just be to just smash the weeds way down into the ground, which is faster, easier, and something a robot can do excellently.
IT'S UNCERTAIN

Quantum computing could potentially solve certain problems much faster than today’s classical computers while using comparatively less power to perform the calculations. Yet the energy efficiency of quantum computing still remains a mystery.
TRAFFIC COP

Whenever someone sends a website request or email, Internet data packets crossing the world can run afoul of data censorship or modification in certain countries, such as China. A new system provides a way for Internet users to route their data around specified “forbidden” countries.
HARD TO GET STAINS OUT

Unless you’re a teenage wizard, making things invisible involves some challenges — cloaking devices tend to be bulky and absorb some of the light they’re trying to reroute. Now a new design may lead to invisibility cloaks that are thinner and don’t lose brightness, rendering them more practical for certain uses.
