Conventionally, this involves electrodes stuck onto the head with conductive gel. The electrodes typically cannot stay mounted to the skin for more than a few days, which limits widespread use of EEGs for applications such as BCIs.</p><p><a href="http://spectrum.ieee.org/tech-talk/biomedical/bionics/a-braincomputing-interface-that-lasts-for-weeks">Read more</a></p><p><img src="/uploads/54ad19735dcd3_855.jpg" unselectable="on"></p><h4></h4><h4></h4><h4></h4><h4><a href="http://spectrum.ieee.org/tech-talk/biomedical/devices/wearable-vitals-tracker">Watch Heart Tissue Twitch on a Chip When Drugged</a></h4><p>By Charles Q.

Bioengineers have embedded pulsating human heart cells in a small microfluidic chip to model effects of drugs on real human hearts.</p><iframe width="560" height="315" src="https://www.youtube.com/embed/oTEp3DcPy-I" frameborder="0" allowfullscreen=""></iframe><p>Animal models are routinely used in the earliest stages of clinical trials, but they often fail to predict human reactions to new drugs because of fundamental differences in biology between species. For instance, the proteins through which ions flow in and out of heart cells can vary in both number and type between humans and other animals.</p><p>Instead, researchers at the University of California, Berkeley, hope that human heart cells grown on a chip could help replace animal testing. These cells are derived from human induced pluripotent stem cells, which are adult cells chemically modified to become many different kinds of tissue. Microfluidic channels around the cells simulate blood vessels, supplying the cells with nutrients and drugs.</p><p><a href="http://watch-heart-tissue-twitch-on-a-chip-when-drugged">Read more</a></p><p><img src="/uploads/54ad198cb3e7b_855.jpg" unselectable="on"></p><p><img src="/uploads/548a3e7b0c3f9_855.jpg" unselectable="on"></p><h4><a href="http://spectrum.ieee.org/video/consumer-electronics/portable-devices/google-glasss-thad-starner-wears-the-future">Google Glass Thad Starner Wears the Future</a></h4><p>Starner has built and sported his own augmented-reality glasses since 1990</p><h4></h4><h4><iframe width="560" height="315" src="https://www.youtube.com/embed/-9lOrqVAzD4" frameborder="0" allowfullscreen=""></iframe></h4><p>By Celia Gorman and Ariel Bleicher Posted <label>1 Jul 2014 | 20:00 GMT</label></p><p><a href="http://www.cc.gatech.edu/home/thad/">Thad Starner</a> has been living the future for more than two decades. As a graduate student at MIT in the early 1990s, he found it frustrating that he couldn’t fully attend to a lecturer and take careful notes at the same time. So he built one of the first wearable computers - a head-up display, which weighed as much as a textbook and connected to a one-handed keyboard called a <a href="http://www.handykey.com/">Twiddler</a>. The contraption let him keep his eye on the speaker while simultaneously typing up what he was learning.</p><p>He’s worn some version of the system ever since. The latest iteration is <a href="http://spectrum.ieee.org/consumer-electronics/gadgets/google-gets-in-your-face">Google Glass</a>, which Starner is helping develop as a technical lead while also keeping his full-time gig as a professor at the Georgia Institute of Technology, in Atlanta. He still uses the Twiddler to browse the Web and take notes on the go without ever pausing to look down at a screen. And because he has more than 20 years of experiences stored in the thumb-size, baby-blue computer at his temple, he can immediately call up relevant but not-quite-fully-remembered details to inform a conversation and almost never has to ask someone for the same information twice.</p><p><a href="http://spectrum.ieee.org/video/consumer-electronics/portable-devices/google-glasss-thad-starner-wears-the-future">Read More</a></p><h4></h4>
