| Nuclear receptors battle it out during metamorphosis in new fruit fly model Posted: 06 Oct 2011 09:54 AM PDT Growing up just got more complicated. Biochemistry researchers have shown for the first time that the receptor for a major insect molting hormone doesn't activate and repress genes as once thought. In fact, it only activates genes, and it is out-competed by a heme-binding receptor to repress the same genes during the larval to pupal transition in the fruit fly.  |
| Vectors of bluetongue get a name Posted: 06 Oct 2011 05:42 AM PDT Scientists of the Antwerp Institute of Tropical Medicine (ITG) have developed a molecular technique to easily and dependably identify the biting midges that spread bluetongue disease. Until know this identification was a problem. The technology helps to understand how the disease spreads, and how to control it. They report in the journal Medical and Veterinary Entomology.  |
