Researchers found that a shortage of the genetic factor KLF4, which regulates endothelial cells lining the interior of blood vessels, makes the lining more prone to the buildup of plaque and fat deposits. Further, the deficiency made the blood vessel more susceptible to clot formation.Mon, 19 Nov 2012 11:43:43 ESThttp://www.sciencedaily.com/releases/2012/11/121119114300.htmhttp://www.sciencedaily.com/releases/2012/11/121119114249.htm A new tool for neuroscientists delivers a thousand pinpricks of light to individual neurons in the brain.

Unlike most other cloaking techniques that rely on transformation optics, this one is based on the influence of the ocean floor?s topography on the various ?layers? of ocean water. At the American Physical Society?s (APS) Division of Fluid Dynamics (DFD) meeting, being held November 18-20, 2012, in San Diego, Calif., Reza Alam, assistant professor of mechanical engineering at the University of California, Berkeley, will describe how the variation of density in ocean water can be used to cloak floating objects against incident surface waves.Mon, 19 Nov 2012 10:45:45 ESThttp://www.sciencedaily.com/releases/2012/11/121119104529.htmhttp://www.sciencedaily.com/releases/2012/11/121119104527.htm Sound waves are commonly used in applications ranging from ultrasound imaging to hyperthermia therapy, in which high temperatures are induced, for example, in tumors to destroy them.

This astonishingly rapid display of botanical movement has long fascinated biologists. Commercially, understanding the mechanism of the Venus fly trap's leaf snapping may one day help improve products such as release-on-command coatings and adhesives, electronic circuits, optical lenses, and drug delivery.Fri, 16 Nov 2012 08:52:52 ESThttp://www.sciencedaily.com/releases/2012/11/121116085204.htmhttp://www.sciencedaily.com/releases/2012/11/121116085201.htm What makes soccer star Christiano Ronaldo?s ?knuckleball? shot so unpredictable and difficult to stop?Fri, 16 Nov 2012 08:52:52 ESThttp://www.sciencedaily.com/releases/2012/11/121116085201.htmhttp://www.sciencedaily.com/releases/2012/11/121116085159.htm Small floating objects change the dynamics of the surface they are on. This is an effect every serious student of breakfast has seen as rafts of floating cereal o?s arrange and rearrange themselves into patterns on the milk. Now scientists have suggested that this process may offer insight into nanoscale engineering processes.Fri, 16 Nov 2012 08:51:51 ESThttp://www.sciencedaily.com/releases/2012/11/121116085159.htmhttp://www.sciencedaily.com/releases/2012/11/121116085157.htm To help planes fly safely through cold, wet, and icy conditions, a team of Japanese scientists has developed a new super water-repellent surface that can prevent ice from forming in these harsh atmospheric conditions. Unlike current inflight anti-icing techniques, the researchers envision applying this new anti-icing method to an entire aircraft like a coat of paint.Fri, 16 Nov 2012 08:51:51 ESThttp://www.sciencedaily.com/releases/2012/11/121116085157.htmhttp://www.sciencedaily.com/releases/2012/11/121116085155.htm As the nearly 8 million U.S. high school students who participate in sports every year suit up this season, scientists are encouraging them to focus on something more valuable than winning ? their health. New research shows fracture and ACL prevention programs are essential in ensuring injuries don?t sideline players.Fri, 16 Nov 2012 08:51:51 ESThttp://www.sciencedaily.com/releases/2012/11/121116085155.htm
