- Massive project reveals shortcomings of modern genome analysis
11-07-2007 · EurekAlert!
The sequencing and comparison of 12 fruit fly genomes -- the result of a massive collaboration of hundreds of scientists from more than 100 institutions in 16 countries -- has thrust forward researchers' understanding of fruit flies, a popular animal model in science. But even human genome biologists may want to take note: The project also has revealed considerable flaws in the way they identify genes.

- Scientists compare 12 fruit fly genomes
11-07-2007 · EurekAlert!
An international research consortium of scientists, supported by the National Human Genome Research Institute, part of the National Institutes of Health, today announced publications comparing the genome sequences of 12 closely related fruit fly species, 10 of which were sequenced for the first time. The analyses identify thousands of novel genes and other functional elements in the insects' genomes, and describe how evolution has shaped the genomes of these important models for genetic research.

- Exploring the dark matter of the genome
06-14-2007 · EurekAlert!
"Junk DNA" is what biologists used to call heterochromatin, the highly repetitive, gene-poor DNA concentrated near the centromeres and telomeres of chromosomes. With the publication of version 5.1 of the genome of the fruit fly, Drosophila melanogaster, led by scientists at Lawrence Berkeley National Laboratory and their colleagues, the term "junk" will be heard less often. Heterochromatin, it appears, is crucial to genome maintenance and cell biology.

- For the fruit fly, everything changes after sex
12-10-2007 · EurekAlert!
The females of many insect species change their behavior right after mating: mosquitoes look for a meal of fresh blood and flies begin to lay eggs. Researchers at the IMP managed to identify the molecular switches that are responsible for these behavioral changes. This could open up new possibilities to control agricultural pests or disease carriers. The science journal Nature reports on the discovery in its current online release.

08-21-2007 · EurekAlert!
A team of scientists reported findings today demonstrating the presence of Marburg virus RNA genome and antibodies in a common species of African fruit bat (Rousettus aegyptiacus). The work, appearing in the Aug. 22 issue of the open-access journal PLoS ONE, was done in collaboration between the Centers for Disease Control and Prevention, Atlanta, GA, the Centre International de Recherches Médicales de Franceville and the Institut de Recherche pour le Développement, Franceville, Gabon.

- Similar brain chemicals influence aggression in fruit flies and humans
04-22-2007 · EurekAlert!
Serotonin is a major signaling chemical in the brain, and it has long been thought to be involved in aggressive behavior in animals and humans. Another brain chemical signal, neuropeptide Y (aka neuropeptide F in invertebrates), is also known to affect an array of behaviors in many species, including territoriality in mice. A new study at The Neurosciences Institute (San Diego) shows that these two chemicals also regulate aggression in the fruit fly, Drosophila melanogaster.
