Researchers at Caltech have obtained the first recordings of brain-cell activity in an actively flying fruit fly. The work—by Michael Dickinson, the Esther M. and Abe M. Zarem Professor of Bioengineering, with postdoctoral scholars Gaby Maimon and Andrew Straw—suggests that at least part of the brain of the fruit fly (Drosophila melanogaster) "is in a different and more sensitive state during flight than when the fly is quiescent," Dickinson says.

For decades, science texts have told a simple and straightforward story about a particular protein—a transcription factor—that helps the embryo of the fruit fly pattern tissues in a manner that depends on the levels of this factor within individual cells. Now Angelike Stathopoulos and her Caltech colleagues have called that paradigm into question.

Caltech and UCLA have announced the establishment of the Joint Center for Translational Medicine (JCTM), which will advance experimental research into clinical applications, including the diagnosis and therapy of diseases such as cancer.

Have you ever found yourself struggling to get your order taken at a crowded bar or lunch counter, only to walk away in disgust as more aggressive customers elbow their way to the front? It turns out that flies do much the same thing, according to biologists from Caltech.

Researchers from Caltech have been able to view in detail, and for the first time, the previously mysterious process by which long chains of a protein called ubiquitin are added by enzymes called ubiquitin ligases to proteins that control the cell cycle. Ubiquitin chains tag target proteins for destruction by protein-degrading complexes in the cell. Their findings, and the innovative process by which they were obtained, are described in this week's issue of Nature.

Scientists at the California Institute of Technology (Caltech) have uncovered evidence of a primitive emotion-like behavior in the fruit fly, Drosophila melanogaster. Their findings, which may be relevant to the relationship between the neurotransmitter dopamine and attention deficit hyperactivity disorder (ADHD), are described in the December issue of the journal Neuron.

The Defense Advanced Research Projects Agency (DARPA) has selected Julia R. Greer, assistant professor of materials science, and Doris Tsao, assistant professor of biology, to participate in its Young Faculty Award (YFA) program. Greer and Tsao are among the 33 "rising stars" from 24 U.S. universities who each will receive grants of approximately $300,000 to develop and validate their research ideas over the next 24 months.

Researchers at Caltech have shown that a highly specific intrabody (an antibody fragment that works against a target inside a cell) is capable of stalling the development of Huntington's disease in a variety of mouse models. "Gene therapy in these models successfully attenuated the symptoms of Huntington's disease and increased life span," notes Paul Patterson, the Anne P. and Benjamin F. Biaggini Professor of Biological Sciences.

Researchers at the California Institute of Technology (Caltech) have proposed a novel model that differs from a widely held hypothesis about the mechanisms by which developing animals pattern their tissues and structures.
