| Even with defects, graphene is strongest material in the world  | Engineering researchers demonstrate that graphene, even if stitched together from many small crystalline grains, is almost as strong as graphene in its perfect crystalline form. This resolves a contradiction between theoretical simulations, which predicted grain boundaries can be strong, and earlier experiments, which indicated they were much weaker than the perfect lattice. | Read More »  Circadian rhythms control body's response to intestinal infections  | Circadian rhythms can boost the body's ability to fight intestinal bacterial infections, researchers have found. | Read More » Lead acts to trigger schizophrenia  | Mice engineered with a human gene for schizophrenia and exposed to lead during early life exhibited behaviors and structural changes in their brains consistent with schizophrenia. Scientists say their findings suggest a synergistic effect between lead exposure and a genetic risk factor, and open an avenue to better understanding the complex gene-environment interactions that put people at risk for schizophrenia and other mental disorders. | Read More » Hubble sees the messy result of a galactic collision  | A new image from the NASA/ESA Hubble Space Telescope captures an ongoing cosmic collision between two galaxies -- a spiral galaxy is in the process of colliding with a lenticular galaxy. The collision looks almost as if it is popping out of the screen in 3-D, with parts of the spiral arms clearly embracing the lenticular galaxy's bulge. | Read More » | |
