Craig Venter, Hamilton Smith, Claire Fraser, and colleagues at TIGR elucidate the first complete genome sequence of a microorganism - Haemophilus influenzae Rd. Since that time, the genome sequences of many important human pathogens, such as M. tuberculosis, Treponema pallidum, Campylobacter jejuni, Helicobacter pylori, Vibrio cholerae, and Legionella pneumophila have been determined.

Localization of cuticle collagens

The nematode cuticle is an extremely flexible and resilient exoskeleton that permits locomotion via attachment to muscle, confers environmental protection and allows growth by molting.

Different species of fruit flies exhibit remarkably different patterns of wing decoration. At the top is the familiar Drosophila melanogaster, the workhorse model organism of genetics, which differs markedly from other fruit fly species. Exploring a single gene that controls pigment deployment in fruit flies, a group led by UW-Madison biologist Sean Carroll has found the molecular switches that control where the pigmentation is deployed on the wing. The finding explains how common genes can be controlled to produce the seemingly endless array of patterns, decoration and body architecture found in animals.

Drug addicts’brain reward circuits often exhibit dulled responses, leading the addicts to seek more of the addictive substance to get their fix. Work in rats indicates that fatty foods may trigger similar responses. Paul Johnson and Paul Kenny at the Scripps Research Institute-Scripps Florida in Jupiter fed rats a high-fat diet, including bacon and sausages, and measured their responsiveness to reward. Animals given prolonged access to the fatty foods needed more stimulation than normal rats to reach a certain reward threshold over time, and gained more weight. Even when the rats were conditioned to associate a light signal with an electric shock to the foot, those with extended access to the high-fat diet continued to eat despite seeing the light, indicating the onset of compulsive-eating behaviour. When the researchers blocked the expression of a dopamine receptor that is downregulated in human drug addicts, rats consuming the rich diet became compulsive eaters more rapidly.
