The findings suggest that feelings of social isolation are linked to alterations in immune system activity, which result in increased inflammatory signalling within the body. This is the first study to show an alteration in genome-wide transcriptional activity linked to a social epidemiological risk factor. It provides a molecular framework for understanding why social factors are linked to an increased risk of diseases where inflammation is thought to be a factor, such as heart disease (...). *  The Molecular Signature Of Loneliness, 2007/09/13, Innovations-report * Contributed by  Atin Das http://www.innovations-report.com/html/reports/life_sciences/report-90770.html ------------------- Primate Behavior Explained By Computer 'Agents' , ScienceDaily Excerpts: The complex behaviour of primates can be understood using artificially-intelligent computer 'agents' that mimic their actions, shows new research (...). Scientists using agents programmed with simple instructions to work out why some primate groups are 'despotic' whilst others are 'egalitarian' - overturning previous theories developed by primatologists. They have also found support for an existing theory of how dominant macaques make it to the safer positions at the middle of their troop without seeming to be pre-occupied with getting there. Using agents programmed with two rules (...) scientists found that their more dominant agents would make their way to the centre of the group.

Terrorists and extremists have set up shop on the Internet, using it to recruit new members, spread propaganda and plan attacks across the world. The size and scope of these dark corners of the Web are vast and disturbing. But in a non-descript building in Tucson, a team of computational scientists are using the cutting-edge technology and novel new approaches to track their moves online, providing an invaluable tool in the global war on terror. (...) This is where the Dark Web project comes in. Using advanced techniques such as Web spidering, link analysis, (...) *  Scientists Use the "Dark Web" to Snag Extremists and Terrorists Online, 07/09/10, NSF Press Release  http://www.nsf.gov/news/news_summ.jsp?cntn_id=110040&org=NSF Barry Wellman _______________________________________________________________________ S.D.
