(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://www.physorg.com/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://www.physorg.com/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://www.physorg.com/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://www.physorg.com/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://www.physorg.com/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://www.physorg.com/news144951765.html Biology Mon, 03 Nov 2008 16:22:45 EST news144951765
