How to Extend Your Mobile Battery Life

Have you ever frantically searched for an outlet to charge your phone? You are not alone. Mobile devices have a large number of different adjustable system settings, but the energy impact of those settings can be difficult to understand for average users, and even for experts. Now, a team of computer scientists from the University of Helsinki, Finland, have measured how long Android phone batteries last with different combinations of settings and environmental conditions. And yes, we are going to tell you how to get the most out of your…

Brain-like Computers from Optical Fibers

Computers that function like a human brain could soon become a reality thanks to new research using optical fibers made of speciality glass. This research has the potential to allow a faster and smarter brain-like computer that can learn and adapt. Researchers from the Optoelectronics Research Centre (ORC) at the University of Southampton, UK, and Centre for Disruptive Photonic Technologies (CDPT) at the Nanyang Technological University (NTU), Singapore, have demonstrated how neural networks and synapses in the brain can be reproduced with optical pulses as information carriers, using special fibers…

University of Vermont scientists Peter Dodds and Chris Danforth led a new Big Data study confirming that humans use more happy words than sad words. Uncategorized 

Preference for Positive, Happy Words

In 1969, two psychologists at the University of Illinois proposed what they called the Pollyanna Hypothesis–the idea that there is a universal human tendency to use positive, happy words more frequently than negative ones. “Humans tend to look on (and talk about) the bright side of life,” they wrote. That speculation has provoked debate ever since. Now, scientists at the University of Vermont have gathered a data set of billions of words to support the 1960s theory. People Use More Happy Words Than Sad Words The researchers collected samples of ten…

Holograms You Can Touch and Feel

Holograms that seem to have mass and can be touched have long been the stuff of science fiction. Now, they are science fact. Tactile technology which creates haptic feedback has been used for years in entertainment (such as game controllers), rehabilitation and even surgical training. Now, researchers from the University of Bristol’s Department of Computer Science have taken a leap forward by using ultrasound to develop a 3D shape in mid-air that can be touched and felt by human hands. The system could change the way 3D shapes are used.…
