The Weird and Wonderful World of 3D Printing
3D printing has been touted as being a manufacturing cure-all for a whole host of different applications. The reality is very different, but this doesn't stop the onslaught of news articles proclaiming 3D printing to be the answer. Here's a roundup of the weird and wonderful world of 3D printing in 2019.
Next-gen solar cells mimic photosynthesis with biological material
Next-generation solar cells that mimic photosynthesis with biological material may give new meaning to the term "green technology."
Primus Power (2019)
Founded in 2009, Primus Power is a Californian startup developing long-duration Zinc-Bromine Redox Flow Batteries for stationary energy storage applications.
Using artificial intelligence to detect discrimination
A new artificial intelligence tool for detecting unfair discrimination--such as on the basis of race or gender--has been created by researchers.
Simple 'smart' glass reveals the future of artificial vision
The sophisticated technology that powers face recognition in many modern smartphones someday could receive a high-tech upgrade that sounds — and looks — surprisingly low-tech.
Using 3D-printing to stop hair loss
Researchers have created a way to grow human hair in a dish, which could open up hair restoration surgery to more people, including women, and improve the way pharmaceutical companies search for new hair growth drugs.
Robots activated by water may be the next frontier
Imagine a robot that could be activated without a motor or electricity. Instead, the robot would be propelled into motion by the water content or humidity in its environment, with its movements controlled by a pattern set into its design.
"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.
