Why Robots and Humans Struggled with DARPA’s Challenge

Tue, 06/09/2015 - 00:00

The falls and fumbles of robots in the DARPA Challenge point to the remaining hurdles for human-robot interfaces.

When some of the world’s most advanced rescue robots are foiled by nothing more complex than a doorknob, you get a good sense of the challenge of making our homes and workplaces more automated.

Quest to Mine Seawater for Lithium Advances

Mon, 06/08/2015 - 00:00

Predicted lithium shortages are leading to novel technologies for recovering the element, now found mostly in salt lakes in South America.

Researchers at Japan’s Atomic Energy Agency have come up with a new method of processing seawater to extract lithium—an element that plays a key role in advanced batteries for electric vehicles and one that, if current predictions for the EV market prove accurate, could be in short supply before the end of the decade.

Rebooting the Human Genome

Wed, 06/03/2015 - 00:00

The official map of the human genome can’t tell you everything about your genes. Does graph theory offer a better way?

AI Supercomputer Built by Tapping Data Warehouses for Their Idle Computing Power

Mon, 06/01/2015 - 00:00

Sentient claims to have assembled machine-learning muscle to rival Google by rounding up idle computers.

Recent improvements in speech and image recognition have come as companies such as Google build bigger, more powerful systems of computers to run machine-learning software. Now a relative minnow, a private company called Sentient with only about 70 employees, says it can cheaply assemble even larger computing systems to power artificial-intelligence software.

Power Sector Finds a New Set of Customers: Cars

Food Technology for All

Tue, 05/26/2015 - 00:00

We may be heading toward a new food economy that’s more competitive and innovative.


For years, the most important food technologies were all about scale. How could we feed a fast-growing population at less expense? By doing everything bigger: food grown on bigger farms was sold by ever-merging global food giants to grocery chains of superstore proportions.

Robots Start to Grasp Food Processing

Tue, 05/26/2015 - 00:00

Advances in robotics make it possible to automate tasks such as processing poultry and vegetables.

It is less striking than Deep Blue’s victory over chess champ Garry Kasparov, but Richard van der Linde says that his robotic hand’s mastery at picking up cabbage is something of a milestone for machines. With the aid of five cameras, plus sensors in its wrist to monitor the resistance it encounters, the three-fingered gripper can carefully pick up a cabbage, reorient it, and place it into a machine that removes the core. “In industry, only humans can do that at the moment,” says van der Linde.
