Researchers create hollow fiber optic cable, almost reach the speed of light
Fiber optic cables are usually made of glass or plastic but those materials actually slow down the transmission of light ever so slightly. Researchers at the University of Southampton in the UK have created a hollow fiber optic cable filled with air that's 1000 times faster than current cables. Since light propagates in air at 99.7 percent of the speed of light in a vacuum, this new hollow fiber optic cable is able to reach data speeds of 10 terabytes (!) per second. Now that's fast. While the idea isn't new, it's previously been hampered by signal degradation when light travels around corners. This new hollow fiber optic cable reduces data loss to a manageable 3.5dB/km, making it suitable for use in supercomputer and data center applications. Isn't science wonderful?

Scientists investigating AI-based traffic control, so we can only blame the jams on ourselves
Ever found yourself stuck at the lights convinced that whatever is controlling these things is just trying to test your patience, and that you could do a better job? Well, turns out you might -- at least partly -- be right. Researchers at the University of Southampton have just revealed that they are investigating the use of artificial intelligence-based traffic lights, with the hope that it could be used in next-generation road signals. The research uses video games and simulations to assess different traffic control systems, and apparently us humans do a pretty good job. The team at Southampton hope that they will be to emulate this human-like approach with new "machine learning" software. With cars already being tested out with WiFi, mobile connectivity and GPS on board for accident prevention, a system such as this could certainly have a lot of data to tap into. There's no indication as to when we might see a real world trial, but at least we're reminded, for once, that as a race we're not quite able to be replaced by robotic overlords entirely.

In partnership with the University of Southampton, Sharp Labs Europe is developing a mobile lab-on-a-chip that spits out results in minutes, potentially putting the test result waiting game to an end. Using microelectronics found in LCDs, the programmable microfluidic square splits microliters of blood -- and potentially other fluids -- into smaller droplets which it subjects to controlled chemical reactions. A single blood sample can be used for multiple tests, so there's no need to endure a barrage of pricks. Folks anxious for snappier lab results may need to sit tight, however, as it could be five to ten years before the device settles into your doctor's office. In the meantime, head past the break to get the scientific lowdown from Sharp Research Supervisor Ben Hadwen.
