| Catastrophic climatic events leave corals facing a decade-long fight for recovery Posted: 01 Jun 2013 10:39 AM PDT Coral reefs can take more than a decade to recover from catastrophic climatic events, with some species taking up to 13 years to recolonise their original habitats, scientists have discovered.  |
| Hubble sees the messy result of a galactic collision Posted: 01 Jun 2013 09:39 AM PDT 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.  |

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.  |
