(AP) -- Think you can do better than Stan Lee? Launching next month, the new massively multiplayer online role-playing game "Champions Online" will let gamers create their own virtual superheroes. Sorry, no Spider-Men or Batmen allowed. http://www.physorg.com/news168849859.html Technology Fri, 07 Aug 2009 08:50:02 EST news168849859 A well-groomed man gets out of a Mercedes. He's holding a Smartphone and wearing a slick business suit and what appear to be $400 Kenneth Cole shoes. You only catch a glimpse, but you've already drawn conclusions about him. A new study in the Journal of Consumer Research examines children's tendencies to draw conclusions about social roles from the products they see. http://www.physorg.com/news167325677.html Other Sciences Mon, 20 Jul 2009 16:40:08 EST news167325677 Researchers at the University of Illinois report that a toxic molecule known to damage cells and cause disease may also play a pivotal role in bird migration. The molecule, superoxide, is proposed as a key player in the mysterious process that allows birds to "see" Earth's magnetic field. http://www.physorg.com/news164892904.html Biology Mon, 22 Jun 2009 12:35:51 EST news164892904 While children look up to and aspire to be like a positive family member or peer, they are more likely to imitate traits of other role models -- including negative role models, which can lead to behavioral problems, according to a Kansas State University researcher. http://www.physorg.com/news154879882.html Medicine & Health Thu, 26 Feb 2009 14:12:07 EST news154879882 In the real world, tracking a person's social network -- which could include hundreds of contacts that serve different purposes -- is nearly impossible. http://www.physorg.com/news153833424.html Other Sciences Sat, 14 Feb 2009 11:31:12 EST news153833424 Canadian researchers have identified a new protein in the progression of breast cancer. According to a recent study from the Université de Montréal and the University of Alberta, published in the Journal of Biological Chemistry, the protein ARF1 plays a critical role in cancer cell growth and the spread of tumours. Targeting this protein with drug therapy may provide hope to women with breast cancer. http://www.physorg.com/news151151667.html Medicine & Health Wed, 14 Jan 2009 10:34:27 EST news151151667 American teens are embracing the subjects of science, technology, engineering and mathematics (STEM) with increasingly positive attitudes; yet many lack the necessary encouragement from mentors and role models in these fields, according to this year's Lemelson-MIT Invention Index. The annual survey, which gauges Americans' perceptions about invention and innovation, also reveals teens' altruistic intentions and feelings of preparedness to pursue careers in STEM fields. http://www.physorg.com/news150542652.html Other Sciences Wed, 07 Jan 2009 09:24:12 EST news150542652 Scientists at Burnham Institute for Medical Research (Burnham) have demonstrated important new roles for the protein kinase complex Cdc7/Dbf4 or Cdc7/Drf1 (Ddk) in monitoring damage control during DNA replication and reinitiating replication following DNA repair. Since Ddk is often deregulated in human cancers, this new understanding of its role in DNA damage control could help shape new cancer therapies. The research was published in the December 24 issue of Molecular Cell. http://www.physorg.com/news150397201.html Biology Mon, 05 Jan 2009 17:00:01 EST news150397201 In a study to be published in the January 09 issue of Experimental Biology and Medicine, Hoover-Plow and co-workers in seeking to define a role of apo(a) in leukocyte recruitment have identified a novel activity of apo(a) apolipoprotein that may function as a natural and cell specific suppressor of the inflammatory response in vivo. In addition, a mechanism for this novel function of apo(a) was also identified: its selective regulation of cytokine production. These effects of apo(a) are independent of its molecular mimicry of Plg. http://www.physorg.com/news149345421.html Medicine & Health Wed, 24 Dec 2008 12:50:21 EST news149345421 Employees with high levels of job autonomy and control over their schedules are more likely to bring their work home with them, according to surprising new research out of the University of Toronto. http://www.physorg.com/news148132322.html Other Sciences Wed, 10 Dec 2008 11:52:02 EST news148132322 In conventional macroeconomic thinking, the money supply is considered the main determinant of long-run inflation. A variety of monetary aggregates have been proposed to measure the money supply. Yet, nowadays, monetary aggregates play little role in monetary policy deliberations at most central banks. A new study in the Journal of Money, Credit and Banking examines the leading arguments for assigning an important role to tracking the growth of monetary aggregates when making decisions about monetary policy. The analysis finds that none of the arguments provides a compelling reason to assign a prominent role to monetary aggregates. http://www.physorg.com/news147529690.html Other Sciences Wed, 03 Dec 2008 12:28:10 EST news147529690 (PhysOrg.com) -- Where would we be without our ability to remember important information or, for that matter, to forget irrelevant details? Thanks to the flexibility of the nerve cell's communication units, called synapses, we are good at both. Up to now, only the receiving side of a synapse was believed to play an active role in this reorganization of the brain, which is thought to underlie our ability to learn but also to forget. An incorrect assumption, as scientists at the Max Planck Institute of Neurobiology in Martinsried could now show. http://www.physorg.com/news146926167.html Medicine & Health Wed, 26 Nov 2008 12:49:27 EST news146926167 When it comes to sex roles in society, what you think may affect what you earn. A new study has found that men who believe in traditional roles for women earn more money than men who don't, and women with more egalitarian views don't make much more than women with a more traditional outlook. http://www.physorg.com/news141278122.html Medicine & Health Mon, 22 Sep 2008 04:55:22 EST news141278122 For years, researchers have known that high blood pressure causes blood vessels to contract and low blood pressure causes blood vessels to relax. Until recently, however, researchers did not have the tools to determine the exact proteins responsible for this phenomenon. http://www.physorg.com/news140952052.html Medicine & Health Thu, 18 Sep 2008 10:20:52 EST news140952052
