(Phys.org) —An international collaboration led by researchers from the NIST Center for Nanoscale Science and Technology (CNST) has demonstrated a novel temporal filtering approach that improves the performance of triggered single photon sources based on solid-state quantum emitters. The technique is compatible with a broad class of photon sources, and is expected to provide significant improvements in areas important for applications in photonic quantum information science. The team included researchers from the CNST, the University of Maryland, the University of Rochester, and Politecnico di Milano, Italy. http://phys.org/news287308609.html Physics Thu, 09 May 2013 08:56:55 EST news287308609 (Phys.org)—Our closest relatives, the great apes, are all endangered and particularly sensitive to infectious diseases. Both chimpanzees and western gorillas experience seasonal variations in fruit availability but little is know about the effect on their health. http://phys.org/news277108398.html Biology Fri, 11 Jan 2013 06:33:33 EST news277108398 Photovoltaic modules deliver power without risks to the environment and climate. But solar-power is expensive. Therefore, it is imperative that the modules last as long as possible, 25 years or more. Fraunhofer researchers in the USA are now investigating materials to protect solar cells from environmental influences to meet that goal. http://phys.org/news260533362.html Technology Tue, 03 Jul 2012 11:22:59 EST news260533362 In a new paper, published today in Science, Sinan Aral, NYU Stern Assistant Professor of Information, Operations and Management Sciences, and his co-author Dylan Walker, a research scientist at Stern, present a new method to measure influence and susceptibility in social networks. http://phys.org/news259512529.html Technology Thu, 21 Jun 2012 15:49:22 EST news259512529 Swiss researchers provide evidence that a protein in the cell nucleus responds to environmental stimuli like a kind of sensor, regulates genes accordingly and thus exchanges information with the cell memory. And that’s not all: cancer drugs that are currently being tested inhibit precisely this protein – and, thanks to new findings, soon maybe even more specifically. http://phys.org/news256894605.html Biology Tue, 22 May 2012 09:00:05 EST news256894605 As acreage of row crops managed with conservation tillage increases, more growers are encountering slugs, elevating their importance as crop pests. Slugs can eat virtually all crops, and they are challenging to control because of the limited number of management tactics that are available. http://phys.org/news250960538.html Biology Wed, 14 Mar 2012 16:15:48 EST news250960538 Scientists at IBM and ABB, the world's largest builder of electricity grids, are using supercomputers to study and potentially develop a new type of high-voltage insulator that will improve the efficiency of transmitting electricity. An improved insulator has the potential to transform the power grid by reducing energy loss and outages caused by material deterioration when exposed to weather. http://phys.org/news239442003.html Technology Wed, 02 Nov 2011 08:40:28 EST news239442003 Children who have a good relationship with their teacher may be protected from expressing aggression and being the target of aggression at school. That's the key finding in a new study of Canadian first graders that appears in the journal Child Development. http://phys.org/news238814707.html Other Sciences Wed, 26 Oct 2011 03:00:01 EST news238814707 Culture is not a trait that is unique to humans. By studying orangutan populations, a team of researchers headed by anthropologist Michael Krützen from the University of Zurich has demonstrated that great apes also have the ability to learn socially and pass them down through a great many generations. The researchers provide the first evidence that culture in humans and great apes has the same evolutionary roots, thus answering the contentious question as to whether variation in behavioral patterns in orangutans are culturally driven, or caused by genetic factors and environmental influences. http://phys.org/news238330487.html Biology Thu, 20 Oct 2011 12:00:12 EST news238330487 Hypothetically speaking, if someone told you that a hypothetical question could influence your judgments or behaviour, would you believe them? http://phys.org/news237115494.html Other Sciences Thu, 06 Oct 2011 10:25:26 EST news237115494 When the scientific and spiritual worlds collide, they do so in the most surprising ways. Classical meteorological and plant science has, in the last century, insisted that dew negatively affects plant life, leading to rot and fungus. But in the Judeo-Christian tradition, dew is most welcomed as an important source of vegetative and plant life, celebrated in poetry and prayer. http://phys.org/news204897823.html Space & Earth Tue, 28 Sep 2010 13:04:09 EST news204897823 For the first time, eye-witness identifications are to be studied to determine if people avoid pointing the finger at someone they like in a police line-up. http://phys.org/news203595249.html Medicine & Health Mon, 13 Sep 2010 11:40:05 EST news203595249 (PhysOrg.com) -- Marketers looking to tap into social influencers as a means to promote their products should recognize that popular people aren't always the trailblazers. http://phys.org/news185044388.html Other Sciences Wed, 10 Feb 2010 17:30:04 EST news185044388 (PhysOrg.com) -- Organizational norms and social cues, not communication overload, are the strongest predictors of whether individuals use their laptops or smart phones to electronically multitask during a meeting, according to researchers at The University of Texas at Austin. http://phys.org/news165685060.html Other Sciences Wed, 01 Jul 2009 16:40:49 EST news165685060 It's a curious paradox. Black adults are more likely to smoke than white adults and most smokers start as teenagers. But statistics show that fewer black youths than whites begin smoking as adolescents. http://phys.org/news161527908.html Medicine & Health Thu, 14 May 2009 13:52:34 EST news161527908 A study in the Feb. 1 issue of the journal Sleep was the first to use twin data to examine the longitudinal link between sleep problems and depression. Results of this study demonstrate that sleep problems predict later depression; the converse association was not found. These findings are consistent with the theory that early treatment of sleep problems may protect children from the development of depression. http://phys.org/news152721800.html Medicine & Health Sun, 01 Feb 2009 14:43:45 EST news152721800 (PhysOrg.com) -- Fishing and hunting are having broad, swift impacts on the body size and reproductive abilities of fish and other commercially harvested species, potentially jeopardizing the ability of entire populations to recover, according to the results of a new study that will appear in the January 12, 2009, online issue of the Proceedings of the National Academy of Sciences. http://phys.org/news151002984.html Biology Mon, 12 Jan 2009 17:16:24 EST news151002984 (PhysOrg.com) -- Genes talk to themselves and to each other to control how a given cell manufactures proteins. But variation in the control of the same gene in two different tissues may contribute to certain human traits, including the likelihood of getting a disease, said a team of geneticists and neuroscientists at Duke University Medical Center. http://phys.org/news149264483.html Biology Tue, 23 Dec 2008 14:21:23 EST news149264483 Research published today reveals for the first time that the different roles of mothers and fathers are influenced by genetics. The study, by the Universities of Exeter and Edinburgh, shows how variation in where males and females put their parenting effort reflects different genetic influences for each sex. http://phys.org/news144951765.html Biology Mon, 03 Nov 2008 16:22:45 EST news144951765
