Science ExpressFluorescently labeled sperm allow direct visualization of their activity within the female reproductive tract of flies. A structured photonic crystal can be used to cloak an object at optical wavelengths and over a wide viewing angle. An appreciable amount of variation in chromatin status and transcription factor binding has a genetic basis. Transcription factor binding sites vary among individuals and are correlated with differences in expression. Developmental flexibility within a stem cell system underpins the robust maintenance of spermatogenesis. |

Efforts have begun to make Illinois in general and Chicago in particular a powerhouse of biotechnology companies like areas on both coasts. Congress should scrap a plan to grant biologic drugs 12 years of protection from generic competitors. The European Commission began a new push to allow farmers in Europe to grow more biotech crops, despite persistent public opposition to the technology. Though scientists hit a wall in their search, a Duke geneticist has ideas on how to renew the hunt. |
