DARPA promised prosthetic limbs that produce realistic sensations, and it’s making good on its word. The agency’s researchers have successfully tested an artificial hand that gave a man a “near-natural” level of touch. The patient could tell when scientists were pressing against specific fingers, even when they tried to ‘trick’ the man by touching two digits at once. The key was to augment the thought-controlled hand with a set of pressure-sensitive torque motors wired directly to the brain — any time the hand touched something, it sent electrical signals that felt much like flesh-and-bone contact.

There’s still a lot of work left to go before this hardware is truly realistic, of course. The sensors don’t cover the entire hand, and they don’t account for temperature or other factors you’ll likely worry about when grabbing objects. Still, this should represent a big step forward. Provided the technology takes off, both amputees and paralysis victims could regain some of the tactility they once had.

The man-made “plant” can create endless oxygen using light and water!

Pioneers have been dreaming about living in outer space for eons, but there’s always been one major roadblock: securing a long-term oxygen supply. Toting around an indefinite supply of O₂ isn’t feasible, and obtaining oxygen from plants in space is difficult, as green vegetation does not thrive in zero gravity environments.

But thanks to graduate student Julian Melchiorri, long-term space travel could soon be a reality. Melchiorri worked with Dezeen and MINI Frontiers to produce the Silk Leaf, an invention capable of sustaining life.

Solar power has been gaining more and more popularity worldwide since the efficiency of solar panels has significantly increased during the recent years, along with the dramatic decrease in the costs. However, its popularity is not only due its affordability to a wider audience but also to the growing awareness about the benefits of clean sources of energy. Yet, the costs of transportation and production often make it extremely difficult to implement solar technology in developing countries. Printed solar cells could offer a solution to this problem.

Thanks to the advances in printed solar cell technology during the past few years, its energy efficiency has increased from 3% to 20%.

“Its success is due to its cost-effectiveness and simplicity. A 10×10 cm solar cell film is enough to generate as much as 10–50 watts per square meter,” said Scott Watkins from the Korean company Kyung-In Synthetic.

Why is cancer so deadly? It spreads and consumes in a process called metastasis. If it stayed put we’d have an easier fight on our hands. Researchers hope this sponge-like implant could offer an intriguing solution, sucking up circulating cancer cells and warning you of their presence early on.

9 out of 10 cancer deaths are caused by spreading to other organs

Time is often cited as ‘our most precious resource’. Beating cancer is no exception to this; if we caught every cancer early success rates would be vastly improved. Curing cancer therefore requires more than simply destroying these cells. It also means improving diagnosis.

Researchers at the University of Massachusetts Medical School are the first to show that it’s possible to reverse the behavior of an animal by flipping a switch in neuronal communication. The research, published in PLOS Biology, provides a new approach for studying the neural circuits that govern behavior and has important implications for how scientists think about neural connectomes.

New technologies have fueled the quest to map all the neural connections in the brain to understand how these networks processes information and control behavior. The human brain consists of 10¹¹ neurons that make 10¹⁵ connections. The total length of neuronal processes in the human brain is approximately 4 million miles long, similar in length to the total number of roads in the U.S. Along these networks neurons communicate with each other through excitatory and inhibitory synapses that turn neurons on or off.

The neuronal roadmap, or connectome, however, doesn’t include information about the activity of neurons or the signals they transmit. How stable are these neural circuits in the brain? Does their wiring constrain the flow of information or the behaviors they control? The complexity of the human brain makes it almost impossible to address these questions.

The concept of artificial intelligence got it’s start at a conference at Dartmouth in 1956. Optimism ran high and it was believed that machines would be able to do the work of humans within 20 years. Alas, it was not to be. By the 1970’s, funding dried up and technology entered the period now known as the AI winter.

Slowly, however, progress was made. Computers became increasingly able to do human tasks, such as character recognition, making recommendations on Amazon and organizing itineraries on travel sites. We didn’t see the algorithms at work, but they were there, computing on our behalf.

So the answer to our technological dilemma is, in fact, all too human. While the past favored those who could retain and process information efficiently, the future belongs to those who can imagine a better world and work with others to make it happen.
