Newly created cancer stem cells could aid breast cancer research
...s. Ince confirmed this behavioral difference by taking a single human breast tissue sample, splitting it in two and growing the cells in the two culture mediums, which select for different cells. Next, he transformed the two populations with the same tumor-initiating genes, injected them in mice and watc...MIT creates 3-D images of living cell
...so the researchers instead created their images by taking advantage of a property known as refractive index. Every material has a well-defined refractive index, which is a measure of how much the speed of light is reduced as it passes through the material. The higher the index, the slower the light travels....European Science Foundation's Forward Look reaches out beyond the endless frontiers

... life. In 2002, the number of elderly American men taking testosterone replacement therapy was nearly 819,000, and the number is growing. The increased use has occurred despite the fact that the cardiovascular effects of chronic testosterone treatment in aging males are largely unknown, and the safety of te...UC experts detail new standard for cleaner transportation fuels

Today, in Part 2, Sperling and Farrell examine many of the specific policy issues involved in designing a low carbon fuel standard. The LCFS, together with Californias vehicle greenhouse-gas standards, will advance automobil...COX-2 inhibitors delay pancreatic cancer precursors in mice
...esults, I certainly wouldnt say everyone should be taking COX-2 inhibitors to protect against cancer, said Eibl. However, with additional studies, we may find COX-2 inhibitors could help prevent pancreatic cancer in high risk populations. Pancreatic cancer is so deadly because it often goes undetected un......smarter breeding programs."
