| More than a good eye: Robot uses arms, location and more to discover objects May 6th 2013, 15:40 A robot can struggle to discover objects in its surroundings when it relies on computer vision alone. But by taking advantage of all of the information available to it -- an object's location, size, shape and even whether it can be lifted -- a robot can continually discover and refine its understanding of objects, say researchers. | | More than a good eye: Robot uses arms, location and more to discover objects May 6th 2013, 15:40 A robot can struggle to discover objects in its surroundings when it relies on computer vision alone.

A young team of researchers investigated the opening and closing mechanisms of these channels. The time consuming calculations were performed using the high performance computer cluster, which is currently the fastest computer in Austria. | | Robots take part in a space simulation May 3rd 2013, 13:41 The two robots Flobi and Nao worked full time for three weeks in an isolation study in Cologne. Scientists were studying how these intelligent assistance systems can help astronauts to keep fit – both physically and mentally. However, it was not just the people who were on trial, but the robots as well. The scientists were testing both their suitability and their durability. The experiment ended on Saturday. | | How to get more followers on Twitter May 2nd 2013, 15:55 What do all Twitter users want? Followers – and lots of them. Looking at a half-million tweets over 15 months, a first-of-its-kind study has revealed a set of reliable predictors for building a Twitter following. | | Researchers look to mathematics, nature, to understand the immune system and its role in cancer May 1st 2013, 13:18 Can patterns in tree branches or the meandering bends in a river provide clues that could lead to better cancer therapies? According to a new study, these self-similar, repeating patterns in nature known as fractals help scientists better understand how the immune system is organized and may one day be used to help improve stem cell transplant outcomes in leukemia patients by predicting the probability of transplant complications. | | Why people quit and come back to Facebook Apr 30th 2013, 14:59 With more than a billion active accounts worldwide, it can be easy to forget that some people don't use Facebook. A new study suggests that "non-use" of the social networking site is fairly common – a quarter of Facebook users take breaks from the site by deactivating their account, and one in 10 completely quit. | |
