Researchers have remotely activated genes inside living animals, a proof of concept that could one day lead to medical procedures in which patients' genes are triggered on demand. The work, in which a team used radio waves to switch on engineered insulin-producing genes in mice, is published today in Science1.

While smartphones are awesome little computers, one of the things that really makes them useful is their built-in sensors - many apps are made possible via a phone's accelerometer, gyroscope, GPS, microphone, camera, or some combination of the bunch. The thing is, though, all of those sensors are stuck in the smartphone. What if you want to use your phone to monitor another device? Well, that's where NODE comes in. The proposed gadget could be placed on or near a device, and would wirelessly relay data from multiple onboard sensors, via Bluetooth.

If you pay for web hosting in order to run any kind of web-based application-from your WordPress blog to a nameplate site to a file-sharing service to a social media data archive-you need to back up your web server's data the same way you back up your computer's data. On database-driven web sites, there are two kinds of data you want to preserve and restore in case of disaster: the files that make up your site (the PHP/Perl/Python, JavaScript, CSS files, etc), and the contents of your database. Further, any good backup system should make both a local copy and a remote copy of the backed-up data.

The kinds of drones making the headlines daily are the heavily armed CIA and U.S. Army vehicles which routinely strike targets in Pakistan - killing terrorists and innocents alike. But the real high-tech story of surveillance drones is going on at a much smaller level, as tiny remote controlled vehicles based on insects are already likely being deployed. Over recent years a range of miniature drones, or micro air vehicles (MAVs), based on the same physics used by flying insects, have been presented to the public. The fear kicked off in 2007 when reports of bizarre flying objects hovering above anti-war protests sparked accusations that the U.S. government was accused of secretly developing robotic insect spies.
