"Particle robot" works as a cluster of simple units

Taking a cue from biological cells, researchers have developed computationally simple robots that connect in large groups to move around, transport objects, and complete other tasks.

Fast, flexible ionic transistors for bioelectronic devices

A team has developed the first biocompatible ion-driven transistor that is fast enough to enable real-time signal sensing and stimulation of brain signals.

A step closer to self aware machines

Robots that are self-aware have been science fiction fodder for decades, and now we may finally be getting closer. Humans are unique in being able to imagine themselves—to picture themselves in future scenarios. Humans can also learn by revisiting past experiences and reflecting on what went right or wrong. While humans and animals acquire and adapt their self-image over their lifetime, most robots still learn using human-provided simulators and models, or by laborious, time-consuming trial and error. Robots have not learned to simulate themselves the way humans do.

How climate impacts solar and wind power supply

One of the challenges with solar and wind power is that, on any given day, the sun isn't always shining, and the wind isn't always blowing when we want it to. Now, zooming out, researchers at Columbia's Earth Institute have found that the same could be true on the scale of years to decades.

Seeking a new element in artificial intelligence: trust

For decades, the cybersecurity community has devised protections to fend off malicious software attacks and identify and fix flaws that can disrupt the computing programs that are central to all aspects of life. Now, a team of researchers has received a grant to develop some of the first tools to bring those same protections to artificial intelligence systems.

Dissecting artificial intelligence to better understand human brain

In the natural world, intelligence takes many forms. It could be a bat using echolocation to expertly navigate in the dark, or an octopus quickly adapting its behavior to survive in the deep ocean. Likewise, in the computer science world, multiple forms of artificial intelligence are emerging - different networks each trained to excel in a different task.

Capturing brain signals with soft electronics

A new technology for long-term stable neural recording. It is based on a novel elastic material composite, which is biocompatible and retains high electrical conductivity even when stretched to double its original length.

Custom carpentry with help from robots

Every year thousands of carpenters injure their hands and fingers doing dangerous tasks such as sawing. In an effort to minimize injury and let carpenters focus on design and other bigger-picture tasks, a team has created AutoSaw, a system that lets nonexperts customize different items that can then be constructed with the help of robots.

Flexible lithium battery for wearable electronics

The rapid development of flexible and wearable electronics is giving rise to an exciting range of applications, from smart watches and flexible displays—such as smart phones, tablets, and TV—to smart fabrics, smart glass, transdermal patches, sensors, and more. With this rise, demand has increased for high-performance flexible batteries. Up to now, however, researchers have had difficulty obtaining both good flexibility and high energy density concurrently in lithium-ion batteries.

Custom ink, ultraviolet light to repeatedly change an object's colour

3-D printing has come a long way since the first rapid prototyping patent was rejected in 1980. The technology has evolved from basic designs to a wide range of highly-customizable objects. Still, there's a big issue: Once objects are printed, they're final. If you need a change, you'll need a reprint.

Robotic network to explore Antarctic ice shelves

One of the biggest unknowns for the future of Earth's climate is Antarctica, where the West Antarctic Ice Sheet holds so much ice that if it collapsed could bring several feet of rising seas. A new partnership will use a robotic network to observe the conditions beneath a floating Antarctic ice shelf.

Floating solar fuels rig for seawater electrolysis

In a single hour, more energy from the sun hits the Earth than all the energy used by humankind in an entire year. Imagine if the sun's energy could be harnessed to power energy needs on Earth, and done in a way that is economical, scalable, and environmentally responsible.
