Researchers make gains in understanding antibiotic resistance

...p yielded new information about the basic chemical principles that underlie binding of the antibiotic to the ribosome, as well as new data about how that mutation confers drug resistance. Steitz and his colleagues also analyzed the structure of five other clinically important antibiotics ?azithromycin, telithr...

Same-Sex Mating Discovered in a Toxic Fungus

...he same-sex mating might also help elucidate basic principles governing the evolution of sex, they said. "Sex is generally beneficial as a means to produce offspring with different gene combinations that can adapt more rapidly to new environments," said HHMI investigator Joseph Heitman, M.D., Ph.D., of Duke, s...

He and the other members of the international sequencing team found that there are more protein coding genes in the organism than they had thought and nearly twic...

Gap-climbing fruit flies reveal components of goal-driven behaviors

...back, and tiptoe. Studying the underlying control principles and neuronal circuits in invertebrates rather than in mice or cats involves fewer ethical problems and is less-expensive research. Using noninvasive neurogenetic techniques for the analysis of the underlying motor-control system, Pick and Strauss sh...

Fundamental discovery -- Bone fracture

...brils together, and this glue works along the same principles that our interdisciplinary research group found in abalone shells. This glue involves sacrificial bonds (with hidden length) that uncoil when the bone is stressed." That interdisciplinary research group included the research groups of Morse and Stuck...
