A team of engineers at the University of California San Diego and La Jolla-based startup Nanovision Biosciences Inc. have developed the nanotechnology and wireless electronics for a new type of retinal prosthesis that brings research a step closer to restoring the ability of neurons in the retina to respond to light. The researchers demonstrated this response to light in a rat retina interfacing with a prototype of the device in vitro.

Social media can warn us about extreme weather events before they happen - such as hurricanes, storms and floods - according to new research by the University of Warwick. Nataliya Tkachenko, with her supervisors in the Department of Computer Science, has found that photographs and key words posted online can signal weather risks developing in specific locations and times - for example, posts about water levels rising can alert the authorities to a potential flood.

Just like real doctors and nurses, online health tools with good - but controlled - communication skills can promote healthier lifestyles, according to researchers. However, if their tone is conversational, these tools may lull users into a false sense of comfort, they add. In a study, people who experienced a back-and-forth interaction with an online health risk assessment website were more likely to follow the health behaviors suggested by the tool,

Great ideas so often get lost in translation - from the math teacher who can't get through to his students, to a stand-up comedian who bombs during an open mic night. But how can we measure whether our audiences understand what we're trying to convey? And better yet, how can we improve that exchange?

A University of Central Florida professor has invented a way to use light to continuously monitor a surgical patient's blood, for the first time providing a real-time status during life-and-death operations. The technology developed by UCF scientist Aristide Dogariu uses an optical fiber to beam light through a patient's blood and interpret the signals that bounce back.

We all know that practice makes us better at things, but scientists are still trying to understand what kinds of practice work best. A research team led by a Brown University computer scientist has found insights about how people improve their skills in a rather unlikely place: online video games.

Greek researchers demonstrated the potential of a self-administered virtual supermarket cognitive training game for remotely detecting mild cognitive impairment (MCI), without the need for an examiner, among a sample of older adults. MCI patients suffer from cognitive problems and often encounter difficulties in performing complex activities such as financial planning.
