Children's moral behavior and attitudes in the real world largely carry over to the virtual world of computers, the Internet, video games and cell phones. Interestingly, there are marked gender and race differences in the way children rate morally questionable virtual behaviors, according to Professor Linda Jackson and her team from Michigan State University in the US. Their research is the first systematic investigation of the effects of gender and race on children's beliefs about moral behavior, both in the virtual world and the real world, and the relationship between the two. The study was published online in Springer's journal, Sex Roles. http://www.physorg.com/news155220473.html Medicine & Health Mon, 02 Mar 2009 12:48:24 EST news155220473 My video-game addiction took on a new, smaller footprint after the holidays. Resigning myself to the fact that my four-year-old iPod was never going to die of its own accord, I proactively put the clunky, white model with the ugly monochrome screen out to pasture and treated myself to a 32-gigabyte iPod Touch ($399). Just doing my bit to jump-start the economy, you know. http://www.physorg.com/news154807601.html Electronics Wed, 25 Feb 2009 18:08:01 EST news154807601 We all love to waste time at work checking out a YouTube video or updating our Facebook profiles, but if you can't control yourself, there's keepmeout.com, a free service that lets you set limits on your Web browsing. http://www.physorg.com/news154199201.html Technology Wed, 18 Feb 2009 17:07:21 EST news154199201 LG Electronics today unveiled the world's first transparent design phone, the LG-GD900, at the Mobile World Congress 2009 in Barcelona, Spain. http://www.physorg.com/news154198449.html Electronics Wed, 18 Feb 2009 16:54:47 EST news154198449 During a research trip to Puerto Rico, ecologist James Porter took samples from underwater nuclear bomb target USS Killen, expecting to find evidence of radioactive matter - instead he found a link to cancer. Data revealed that the closer corals and marine life were to unexploded bombs from the World War II vessel and the surrounding target range, the higher the rates of carcinogenic materials. http://www.physorg.com/news154171806.html Space & Earth Wed, 18 Feb 2009 09:32:30 EST news154171806 Alcohol and iron are believed to have a synergistic effect in the development of liver injury. Furthermore, alcohol enhances iron absorption. Primary hemochromatosis is a genetic disorder, mostly resulting from mutations in the HFE gene, with a disturbance in the iron metabolism which leads to iron accumulation that may eventually result in liver disease. However, data regarding an association between iron metabolism, HFE mutations and alcoholic liver disease are inconclusive at present. http://www.physorg.com/news154096750.html Medicine & Health Tue, 17 Feb 2009 12:39:43 EST news154096750 Intentionally contaminated Chinese milk killed several children and sickened 300,000 more, causing concern around an increasingly connected world economy.

In addition, it remains a primary source for acquiring new knowledge on the liver pathology. Demand for precise evaluations of the fibrosis and inflammatory tissue detectable in liver biopsy samples has been fuelled by the need to understand the closest-to-real effects of new antiviral molecules on the lesions characterising the histological patterns of chronic viral, toxic, metabolic and autoimmune diseases. http://www.physorg.com/news149924141.html Medicine & Health Wed, 31 Dec 2008 05:35:41 EST news149924141 Ricin, a lectin from the castor bean plant Ricinus communis is considered one of the most potent plant toxins. Ricin poisoning can cause severe tissue damage and inflammation and can result in death. Most accidental exposures occur by ingestion of the seeds of castor beans whereby the toxin is released after the seed coat is damaged. The ingested toxin causes severe gastrointestinal damage with symptoms and death due to multiorgan failure or cardiovascular collapse. http://www.physorg.com/news149783869.html Medicine & Health Mon, 29 Dec 2008 14:37:49 EST news149783869 In recent years HIFU has been widely used for the treatment of solid tumors, such as liver tumor, bone tumor, and breast cancer. The mechanism for therapeutic actions of HIFU includes thermal effects and non-thermal effects with the latter dominated by cavitational effects. Adjusting acoustic parameters of pulsed high intensity focused ultrasound (PHIFU) can control thermal effects and non-thermal effects; short duty cycle and high intensity favors the occurrence of cavitation. Ultrasound contrast agent (UCA) can enhance cavitational effects. Lesions caused by non-thermal effects have characteristic pathological changes quite different from those of thermal lesions. http://www.physorg.com/news149769705.html Medicine & Health Mon, 29 Dec 2008 10:41:45 EST news149769705 (PhysOrg.com) -- For years, many physicists have accepted that dark matter is composed of weakly interacting massive particles (WIMPs). The fact that WIMPs can naturally explain the amount of dark matter in the universe - left over from the Big Bang - has been described as the `WIMP miracle.` http://www.physorg.com/news148316483.html Physics Fri, 12 Dec 2008 15:01:23 EST news148316483 Hackers beware.

World records tumbled at the Beijing Olympics. Usain Bolt shattered both the 100m and 200m world records, knocking tenths of a second off each. People have been getting faster and faster over the last few decades, which made marathon runner Mark Denny, from Stanford University, wonder whether last century's massive increase in population could account for these dramatic improvements. He also wondered whether there are absolute limits on running speeds and, if so, how close are we to them? http://www.physorg.com/news147080936.html Biology Fri, 28 Nov 2008 07:48:56 EST news147080936 (PhysOrg.com) -- The University of Manchester has teamed up with Manchester based licensed textile company Character World and brand management firm Brand 360 to produce an innovative range of 3D Spider-Man duvet covers and bed linen. http://www.physorg.com/news146930496.html Technology Wed, 26 Nov 2008 14:01:36 EST news146930496 The dream of using the internet to allow people to access as much computer processing and storage power as they need, when they need it, is a step closer thanks to European researchers. http://www.physorg.com/news146410563.html Technology Thu, 20 Nov 2008 13:36:03 EST news146410563 (PhysOrg.com) -- A research team, led by North Carolina State University's Dr. Mitzi M.
