Scientists separate plasma from blood with working biochip

Disposable biotech sensors won't let you diagnose your own diseases quite yet, but we've taken the first step -- a research team spanning three universities has successfully prototyped a lab-on-a-chip. Called the Self-powered Integrated Microfluidic Blood Analysis System (or SIMBAS for short, thankfully), the device takes a single drop of blood and separates the cells from the plasma. There's no electricity, mechanics or chemical reactions needed here, just the work of gravity to pull the fluid through the tiny trenches and grooves, and it can take as little as ten minutes to produce a useful result. It's just the first of a projected series of devices to make malady detection fast, affordable and portable. Diagram after the break!

4 Free Apps For Discovering Great Content On the Go

1. StumbleUpon The granddaddy of discovering random cool stuff online, StumbleUpon will celebrate its 10th anniversary later this year — but its mobile app is less than a year old. On the web, its eight million users have spent the last decade recommending (or disliking) millions of webpages with a thumbs up / thumbs down system on a specially installed browser bar. The StumbleUpon engine then passes on recommendations from users whose interests seem similar to yours. Hit the Stumble button and you’ll get a random page that the engine thinks you’ll like. The more you like or dislike its recommendations, the more these random pages will surprise and delight. Device : iPhone , iPad , Android 2. iReddit Reddit is a self-described social news website where users vote for their favorite stories, pictures or posts from other users, then argue vehemently over their meaning in the comments section. In recent years, it has gained readers as its competitor Digg has lost them.

‘Wireless’ humans could backbone new mobile networks

People could form the backbone of powerful new mobile internet networks by carrying wearable sensors. The sensors could create new ultra high bandwidth mobile internet infrastructures and reduce the density of mobile phone base stations.Engineers from Queen’s Institute of Electronics, Communications and Information Technology are working on a new project based on the rapidly developing science of body-centric communications.Social benefits could include vast improvements in mobile gaming and remote healthcare, along with new precision monitoring of athletes and real-time tactical training in team sports, an institute release said.The researchers are investigating how small sensors carried by members of the public, in items such as next generation smartphones, could communicate with each other to create potentially vast body-to-body networks.The new sensors would interact to transmit data, providing ‘anytime, anywhere’ mobile network connectivity.Simon Cotton from the i
