With concerns often expressed about youth crime and violence in the UK, researchers have been investigating what young people really think about living in an inner-city neighbourhood that has high levels of deprivation, crime and gang activity. http://phys.org/news287835134.html Other Sciences Wed, 15 May 2013 11:12:39 EST news287835134 As people enter old age it can become increasingly difficult to maintain a good quality of life without help. Perhaps a faltering memory leads to missed meals or drinks, or a decrease in mobility leads to loneliness and social isolation. Many elderly people are lucky enough to have a carer, but sometimes that person - maybe a partner - is also of a similar age and may need help caring for the other. http://phys.org/news285576431.html Electronics Fri, 19 Apr 2013 07:47:17 EST news285576431 Hollywood-style robots able to shoot people without permission from their human handlers are a real possibility and must be banned before governments start deploying them, campaigners warned Monday. http://phys.org/news272554217.html Electronics Mon, 19 Nov 2012 13:30:25 EST news272554217 Robots are increasingly being used in place of humans to explore hazardous and difficult-to-access environments, but they aren't yet able to interact with their environments as well as humans. If today's most sophisticated robot was trapped in a burning room by a jammed door, it would probably not know how to locate and use objects in the room to climb over any debris, pry open the door, and escape the building. http://phys.org/news268996593.html Electronics Tue, 09 Oct 2012 10:16:41 EST news268996593 During the breeding season, polygynous male pectoral sandpipers that sleep the least sire the most young. A team of researchers headed by Bart Kempenaers from the Max Planck Institute for Ornithology in Seewiesen has now discovered this extraordinary relationship. During three weeks of intense competition under the constant daylight of the Arctic summer, males actively court females and compete with other males. Using an innovative combination of tags that monitored movement, male-female interactions, and brain activity in conjunction with DNA paternity testing, the authors discovered that the most sleepless males were the most successful in producing young. As the first evidence for adaptive sleep loss, these results challenge the commonly held view that reduced performance is an evolutionarily inescapable outcome of sleep loss. http://phys.org/news263735918.html Biology Thu, 09 Aug 2012 14:00:05 EST news263735918 How do dogs behave when their ability to exert self-control is compromised? Are they more likely to approach dangerous situations or stay well away? According to a new study by Holly Miller, from the University of Lille Nord de France, and colleagues, dogs that have 'run out' of self-control make more impulsive decisions that put them in harm's way. The work was just published online in Springer's Psychonomic Bulletin & Review. http://phys.org/news252583901.html Biology Mon, 02 Apr 2012 11:40:01 EST news252583901
