Just When You Thought Magnets Weren’t Magic; Magnets Are Mechanisms This is magic, big news, both, or neither. It’s so exciting to see magnets behave in this bizarre and wonderful way that we think it’s hard to forecast where this will go. Shown above is a pair of magnets that have several modes of operation.
MIT researchers can listen to your conversation by watching your potato chip bag Imagine someone listening in to your private conversation by filming the bag of chips sitting on the other side of the room. Oddly specific, I know, but researchers at MIT did just that: They’ve created an algorithm that can reconstruct sound (and even intelligible speech) with the tiny vibrations it causes on video. When sound hits an object, it makes distinct vibrations. “There’s this very subtle signal that’s telling you what the sound passing through is,” said Abe Davis, a graduate student in electrical engineering and computer science at MIT and first author on the paper. But the movement is tiny – sometimes as small as thousandths of a pixel on video.

These Battery-Free, WiFi Devices Run On Radio Waves In the last decade, mobile devices have become radically smaller and more powerful. The list of tech-related tasks that the miniature black monolith we all tote around has grown longer by the year. The next step in technology’s great disappearing act? Absorption into our clothes, body, and environment. The question of how best to power that next step, however, remains an open one. Wearable and Internet-of-Things technologies need to be ‘on’ all the time.
Researchers develop new lens for terahertz radiation Terahertz radiation is a relatively unexplored slice of the electromagnetic spectrum, but it holds the promise of countless new imaging applications as well as wireless communication networks with extremely high bandwidth. The problem is that there are few off-the-shelf components available for manipulating terahertz waves. Now, researchers from Brown University's School of Engineering have developed a new type of lens for focusing terahertz radiation (which spans from about 100 to 10,000 GHz). The lens, made from an array of stacked metal plates with spaces between them, performs as well or better than existing terahertz lenses, and the architecture used to build the device could set the stage for a range of other terahertz components that don't currently exist.
Liquid Metal Makes Stretchable Circuits Electronic circuits are sensitive little buggers. Bend, flex or twist them and they typically snap in half. That’s because electronics are made from brittle metals. But scientists at EPFL in Switzerland have found a way to turn liquid metal, an alloy of gold and gallium, into a flexible circuit that can be stretched to four times its original size. 10 Shapeshifting Techs: The Morph, the Merrier The potential applications are wide-ranging and incredibly useful.
Robotic-Farming Grows With the Ladybird My following article below was originally published by SERIOUS WONDER: Robots are going to steal your job, but that’s okay, because they’ll be liberating us away from boring, strenuous and monotonous labor and give us far more time in doing what we truly want to do. Agriculture will not be an exception, and is in fact moving fast in becoming a model of what the entire workforce will eventually transform into.
Goodyear unveils spherical concept tires for autonomous cars Goodyear has taken the wraps off two new concept tires designed specifically for autonomous vehicles. The most interesting of the two is the Eagle-360, a spherical concept tire that can move in any direction using, in part, a magnetic levitation system. As exciting as the Eagle-360 is, it isn’t reasonable for the upcoming fleet of self-driving cars. To meet present-day needs, Goodyear has also introduced its new IntelliGrip concept tires.
Siri’s Inventors Are Building a Radical New AI That Does Anything You Ask Viv was named after the Latin root meaning live. Its San Jose, California, offices are decorated with tchotchkes bearing the numbers six and five (VI and V in roman numerals). Ariel Zambelich When Apple announced the iPhone 4S on October 4, 2011, the headlines were not about its speedy A5 chip or improved camera. Instead they focused on an unusual new feature: an intelligent assistant, dubbed Siri. At first Siri, endowed with a female voice, seemed almost human in the way she understood what you said to her and responded, an advance in artificial intelligence that seemed to place us on a fast track to the Singularity.
