Scientists identify a gene important for the daily rhythms of the sleep-wake cycle Northwestern University scientists have discovered a new mechanism in the core gears of the circadian clock. They found the loss of a certain gene, dubbed "twenty-four," messes up the rhythm of the common fruit fly's sleep-wake cycle, making it harder for the flies to awaken. The circadian clock drives, among other things, when an organism wakes up and when it sleeps. While the Northwestern study was done using...

Research published in the journal GENETICS suggests that being around the opposite sex activates genes in Drosophila melanogaster that cause them to perform certain courtship behaviors Scientists from Texas have made an important step toward understanding human mating behavior by showing that certain genes become activated in fruit flies when they interact with the opposite sex. This research, published in the January 2011 issue of the journal GENETICS (http://www.genetics.org), shows that...

Biologists at Texas A&M University have made an important step toward understanding human mating behavior by showing that certain genes become activated in fruit flies when they interact with the opposite sex. Their research, published in the January 2011 issue of the journal GENETICS, shows that courtship behaviors may be far more influenced by genetics than previously thought. In addition, this new understanding as to why and how these genes become activated within social contexts may...

Clues about how the human gut helps regulate our appetite have come from a most unusual source "“ fruit fly feces. Scientists at the University of Cambridge are using the fruit fly to help understand aspects of human metabolism, including why pregnant women suffer from bloating and constipation, and even the link between a low calorie diet and longevity. Although scientists have known for some time that there are as many as 500 million nerve cells in our gut, the sheer complexity that...

(Ivanhoe Newswire) "“ New genes that evolved a mere one million years ago- a blink in evolutionary history- can be just as essential for life as ancient genes, according to this study. Evolutionary biologists have always believed that the gene most important to life are ancient and conserved, handed down form species to species as the "bread and butter" of biology. New genes that arise in species split off from their ancestors and were thought to serve a less important role- the...

Scientists today published catalogs of the fruit fly and roundworm's functional genomic elements: DNA sequences in the genome that carry the instructions and determine which genes are turned on and off at various times in different cells. Initially sequenced as part of the Human Genome Project, the genomes of the fruit fly, Drosophila melanogaster, and the roundworm, Caenorhabditis elegans, are powerful models for understanding human biology and disease, as many functional genomic elements...

The most detailed annotation yet of the fruit-fly genome points the way to understanding the genomes of all organisms In the past decade researchers have made astonishing progress in the rapid and accurate sequencing of genomes from all realms of life. Yet the listing of chemical base pairs has gotten far ahead of understanding how the information they contain becomes functional. Even the best-understood genomes conceal mysteries. Genetic information carried by DNA and RNA operates together...

Using fruit flies as a model to study embryo formation, scientists report in Nature Cell Biology that molecular breakdown of a protein called Bicoid is vital to normal head-to-tail patterning of the insect's offspring. Published online by the journal Dec. 19, the study shows how Bicoid is targeted for molecular degradation by a newly identified protein the researchers named Fates-shifted (Fsd). Without the interaction between Bicoid and Fsd, fruit fly embryos are improperly formed and...

Surprise finding reverses core evolutionary biology assumptions on development New genes that have evolved in species as little as one million years ago "“ a virtual blink in evolutionary history "“ can be just as essential for life as ancient genes, startling new research has discovered. Evolutionary biologists have long proposed that the genes most important to life are ancient and conserved, handed down from species to species as the "bread and butter" of biology. New genes...

The brain, a complex network The human brain is composed of 100 billion individual nerve cells which communicate with each other via a complex network of connections. Errors in communications of these cells are often at the basis of brain and nerve diseases such as Alzheimer's and multiple sclerosis. In the search for possible solutions to these diseases, one important aspect is to understand how the connections between nerve cells develop. Drosophila as a model organism The fruit fly,...
