Researchers say they can predict epileptic seizures an hour in advance
Their wearable device uses machine learning algorithms to analyze EEG signals.
Researchers can 'steal' data by tracking a PC monitor's brightness
There are already ways to siphon data from computers without a network connection or old-fashioned physical theft, but this might be one of the cleverer examples. Researchers have found a way to steal data from "air-gapped" computers (that is, no way to connect to other devices) using an LCD's brightness. The approach has a compromised computer relay imperceptible changes in the LCD's RGB color values that a camera-equipped device can detect. You could theoretically trick someone into loading malware on the target system through a USB drive and use nearby hijacked security cameras to transmit that information.
Snail turned into living battery, should have taken the blue pill
You know how those mad scientists at DARPA are obsessed with generating power from insects? A team from Clarkson University, New York and Ben-Gurion University, Israel has gone one better by turning a Snail into a cybernetic power generator. A pair of Buckypaper electrodes were charged by the electro-chemical reactions in the slow-moving invertebrates "hemolymph," its equivalent to blood. Its hoped the Snails will provide a sustainable way to power listening devices for the Department of Homeland Security, so if you suddenly find your crawlspace full of gastropods, be careful what you say.

Ben-Gurion University's wall-climbing robots scale defenses, haunt nightmares, stain faux-finishes (video)
We've seen plenty of prototype mechanisms for autonomous dealies that can scale the straightest of walls, but never have we seen so many gathered together into what can only be called a festival of disconcerting feats of robotic ingenuity. One uses magnets, one has little claws, and one uses integrated hot glue guns that would leave you with no doubt that something sticky had been exploring your walls. They were all developed by a team of engineers working with Amir Shapiro at Ben-Gurion University in Israel, where he studies biomimetrics: technology that tries to do what animals do. Applications for all this? The Israeli military is apparently quite interested, a force that we will be working extra hard to stay within the good graces of from now on.
Researchers developing danger-sensing BioPen
Scientists at Ben Gurion University in Israel are out to make detecting dangerous biological agents as simple as a pregnancy test with their yet-to-be-completed BioPen, which they say could eventually be in use everywhere from the battlefield to the veterinary lab. The pen uses a modified form of Enzyme-Linked Immunosorbent Assay (or ELISA) antigen detection to detect potentially harmful compounds, and can apparently also be used to determine if water is drinkable, along with ratting out environmental toxins, Ebola, Hepatitis B and C, Dengue, West Nile virus, and bird flu, among other nasty things. It works by taking a blood sample with a disposable tip, which is then automatically processed in the non-disposable cap, delivering the verdict in twenty minutes or less. Of course, they haven't actually gotten it into pen size yet -- for that, they're looking for one or two million dollars of funding -- but when/if it gets fully developed, they foresee the BioPen being a fairly affordable option, costing about $15 per test.
