| Twitter data used to track vaccination rates and attitudes Posted: 13 Oct 2011 03:48 PM PDT The first case study in how social-media sites can affect the spread of a disease has been designed and implemented by a scientist studying attitudes toward the H1N1 vaccine. The method is expected to be repeated in the study of other diseases.  |
| 'Robot biologist' solves complex problem from scratch Posted: 13 Oct 2011 01:29 PM PDT Scientists have taken a major step toward developing robot biologists. They have shown that their system, the Automated Biology Explorer, can solve a complicated biology problem from scratch.  |
| Aggressive piranhas bark to say buzz off Posted: 13 Oct 2011 05:52 AM PDT Piranhas are best known for their bite, but did you know they make sounds too?

However, scientists are now working on a textile coating which automatically seals small holes and tears in the surface layer of waterproof work-wear.  |
