The runners-up (a tie for second), meanwhile, worked themselves to the bone and relied on "heavy metal" riffs. All three, narrowed down from a group of more than a dozen talented Harvard seniors, impressed the panel faculty judges with their performances (and of course, those colorful PowerPoint presentations).</p><p><a href="http://harvardscience.harvard.edu/engineering-technology/articles/engineering-idol">read more</a></p> Mon, 26 Mar 2007 06:26:49 -0400 70652986 3803 at http://harvardscience.harvard.edu http://harvardscience.harvard.edu/medicine-health/articles/getting-acl-tears-heal-themselves <!--paging_filter--><p>Orthopedic surgeon Martha Murray reports that a collagen gel enriched with blood platelets can stimulate natural healing of a partial anterior cruciate ligament (ACL) tear. Murray and colleagues at Harvard-affiliated Children's Hospital Boston found the gel can help regenerate the knee ligament and restore mechanical strength. Their findings are preliminary, but could lead to a shift away from thinking that the ACL has to be completely replaced after an injury, says Murray. More than 100,000 Americans a year suffer from the knee injury. <p>The research is published in the April 2006 Journal of Orthopaedic Research. The current study was funded by the National Institute of Arthritis and Musculoskeletal and Skin Diseases, the National Football League, the Orthopedic Research and Education Foundation and the Orthopaedic Foundation of Children's Hospital Boston.</p> Mon, 26 Mar 2007 06:25:55 -0400 70652986 3781 at http://harvardscience.harvard.edu
