The LHC and the Hunt for Hidden Dimensions In a talk at the SETI (Search for Extraterrestrial Intelligence) Institute last Wednesday, SLAC physicist JoAnne Hewett explained how the Large Hadron Collider can solve a puzzle that has vexed physicists for more than a century: the proposed existence of extra dimensions. Describing the exact location of Hewett's talk requires reference to the four dimensions that people experience: three spatial dimensions (to locate the SETI Institute in Mountain View, CA), and time (Wednesday, February 5). Theoretical physicists suggest that the universe includes up to six or seven additional dimensions too small to be observed. Finding evidence of these phantom dimensions would solve several of the biggest problems in modern physics, notably showing that all fundamental forces can be combined into one, and possibly providing evidence for string theory.

Wondering whether that jar of peanut butter in your pantry is safe? Web resources from the US Food and Drug Administration and Centers for Disease Control and Prevention can help. The FDA Web site includes access to a database of recalled peanut products (right). A single Web page from the CDC draws together sources of news and information, including Web pages, blogs, podcasts, video, e-mail lists—even a Twitter feed and a 3-D virtual world in Second Life. For that collection, see the CDC's Social Media Tools for Consumers and Partners: Peanut Butter and Peanut-Containing Product Recalls Related to Salmonella Infections.  Cyclotron KidsWith aid from Jefferson Laboratory, a group of high school students who attended space camp together are working to build a cyclotron. The students' goal is to be the first teenagers to produce antimatter. Click on the image at right to watch the YouTube video about the students and their project. Hollywood Comes to CERNCERN today hosted a visit from actors Tom Hanks and Ayelet Zurer and director Ron Howard as they unveiled exclusively some select footage from their new film adaptation of Dan Brown's novel Angels & Demons, set for worldwide release by Sony Pictures on May 15. When Sony Pictures first contacted CERN early in 2007 about filming part of Angels & Demons there, the laboratory quickly saw an opportunity and was excited to participate. "The fact that Angels & Demons is a best-selling novel and now a Hollywood movie gives us the opportunity to show how exciting the reality of antimatter research is," said CERN Research Director Sergio Bertolucci. "Both fiction and science want to take us from the ordinary to the extraordinary; the difference is that science has to operate entirely within reality." Read more on Interactions. |
