| Venus' transit and the search for other worlds Posted: 05 Jun 2012 02:10 PM PDT It's the final opportunity of the century to witness the rare astronomical reunion of the sun, Venus and Earth. On Tuesday, June 5 or 6, 2012, depending on your location, Venus will make its presence in the solar system visible from Earth's day side. Using special eye safety precautions, viewers may see Venus as a small dot slowly drifting across the golden disk of the sun. |
| Milk ingredient does a waistline good Posted: 05 Jun 2012 10:07 AM PDT A natural ingredient found in milk can protect against obesity even as mice continue to enjoy diets that are high in fat. The researchers liken this milk ingredient to a new kind of vitamin. |
| Keeping up with embryogenesis: New microscope tracks cells as they move and divide Posted: 05 Jun 2012 09:17 AM PDT The transformation of a fertilized egg into a functioning animal requires thousands of cell divisions and intricate rearrangements of those cells. That process is captured with unprecedented speed and precision by a new imaging technology that lets users track each cell in an embryo as it takes shape over hours or days. |
| Faster, more sensitive photodetector created by tricking graphene Posted: 05 Jun 2012 07:28 AM PDT Researchers have developed a highly sensitive detector of infrared light that can be used in applications ranging from detection of chemical and biochemical weapons from a distance and better airport body scanners to chemical analysis in the laboratory and studying the structure of the universe through new telescopes. |
| Splitting the unsplittable: Physicists split an atom using quantum mechanics precision Posted: 05 Jun 2012 07:28 AM PDT Researchers have just shown how a single atom can be split into its two halves, pulled apart and put back together again. While the word "atom" literally means "indivisible," the laws of quantum mechanics allow dividing atoms -- similarly to light rays -- and reuniting them. The researchers want to build quantum mechanics bridges by letting the atom touch adjacent atoms while it is being pulled apart so that it works like a bridge span between two pillars. |
