Biologists determine genetic blueprint of social amoeba

...y researchers as a model genetic system, much like fruit flies and laboratory mice, to gain a better understanding of human diseases. The scientific details of this seven-year-long genetic sequencing effort, which involved 97 scientists from 22 institutions in five countries, are contained in a paper feat...

Scientists find that protein controls aging by controlling insulin

... phenomenon found in animals ranging from worms to fruit flies to mice. The mice with higher levels of Klotho had more insulin in their system than the normal mice, suggesting that the Klotho mice were resistant to insulin; they had to make more of it to make up for the resistance. The opposite was true ...

Pinpointing the cause of a neurodegenerative disorder

...1 can cause the pathology of SCA1. Turning to the fruit fly, Drosophila, a favorite of geneticists, Zoghbi and her colleagues showed that a particular domain of Ataxin-1 was responsible for causing the flies to lose sensory neurons, but the domain's function remained unknown. Then, a finding by co-author ...

Fruit fly studies open new window on cancer research

Scientists studying the humble fruit fly have found a family of proteins that enhances ... now looking at whether human equivalents of these fruit fly genes act in the same way. If they do, then new drugs or even dietary advice could block their a...

Gambling monkeys give insight into neural machinery of risk

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

...d structure of goal-oriented motor programs in the fruit fly Drosophila. The findings are reported in Current Biology by Roland Strauss, of the University of Wurzburg, and Simon Pick, of the University of Ulm, both in Germany. In their studies, the researchers presented freely walking flies with a chasm...

Carnegie Mellon University research reveals how cells process large genes

...process, which the investigators discovered in the fruit fly Drosophila, has been conserved over tens of millions of years of insect evolution and also appears likely to occur in humans, according to the investigators. "While some scientists have suspected that large introns might not be removed in one p...

Reversal of role for a viral protein associated with the development of lymphoma

Bacteria recognize antimicrobials, respond with counter-defenses

Many living things, from fruit flies to people, naturally produce disease-fighting chemicals, called antimicrobial peptides, to kill harmful bacteria. In a counter move, some disease-causing bacteria have evolved antimicrobial detectors. The bacteria sense the presence of antimicr...
