Bar flies: fruit flies help unravel the genetics of alcohol sensitivity
10-30-2007 · EurekAlert!Research published in the online open-access journal Genome Biology this week has identified a number of genes that are associated with sensitivity to alcohol in fruit flies. It is hoped that these findings will help researchers uncover the genetic basis of drinking behavior in humans.

- 'Drunk' fruit flies could shed light on genetic basis of human alcohol abuse
10-19-2006 · EurekAlert!
Fruit flies get "drunk," just like humans, when exposed to large amounts of alcohol and may in future help to explain why some people are genetically predisposed to alcohol abuse. Humans and fruit flies respond to alcohol in a very similar way at the gene level, according to a study published today in the open access journal Genome Biology.

- With fruit fly sex, researchers find mind-body connection
11-30-2006 · EurekAlert!
The fruit fly gene "doublesex" is responsible for ensuring that male flies look male and females look female. New Brown University research led by biologist Michael McKeown shows that doublesex not only helps shape bodies but also shapes behavior, acting with together with the gene "fruitless" to guide flies' courtship routines and responses. The finding, published in Nature Genetics, shows that sexual development in flies -- and, perhaps, in humans -- is a more complicated proposition than previously thought.

- In fruit flies, homosexuality is biological but not hard-wired
12-09-2007 · EurekAlert!
A team of neurobiologists led by UIC researcher Dave Featherstone has discovered that homosexuality in fruit flies is controlled by a novel regulator of synapse strength. By harnessing this discovery, the researchers are able to use either genetics or drugs to turn fly homosexual behavior on and off within hours.

- Lush or lightweight?
10-31-2007 · EurekAlert!
Some fruit flies can drink others under the table. Now, scientists at North Carolina State University have a few more genetic clues behind why some flies are more sensitive to alcohol than others. And the results might lead to more knowledge about alcoholism in humans.

- 3-D fruit fly images to benefit brain research
09-04-2007 · EurekAlert!
In a paper published on September 5 in the online, open-access journal PLoS ONE, a team led by Mary O'Connell of the MRC Human Genetics Unit describe how they have already used an imaging technique called optical projection tomography (OPT) to image individual cavities within the brain of an aging fly and see the brain deteriorate. The OPT images could help to speed up genetic research into Alzheimer's and other human diseases affecting brain cells.

- Fruit fly gene from 'out of nowhere' is discovered
07-23-2007 · EurekAlert!
Scientists thought that most new genes were formed from existing genes, but Cornell researchers have discovered a gene in some fruit flies that appears to be unrelated to other genes in any known genome.

- Picky-eater flies losing smell genes
04-02-2007 · EurekAlert!
The specialist fruit fly Drosophila sechellia is losing genes for smell and taste receptors 10 times faster than its generalist relative Drosophila simulans. The findings could help researchers understand how some insect pests adapt to feeding on a particular plant.

- Tracing the pathways of neurofibromatosis
01-18-2007 · EurekAlert!
New research into the mechanisms of neurofibromatosis finds that flaws in the gene Nf1 can lead to a biochemical domino effect that results in tumors. The research, which appears in the January 10 issue of the Journal of Neuroscience, seeks to identify the biochemical pathway responsible for tumors in people with the genetic disorder. Researchers built their case based on evidence from dozens of painstaking experiments on genetically engineered fruit flies.

- Flies don't buzz about aimlessly!
04-03-2007 · EurekAlert!
How you ever stopped to wonder how a fruit fly is able to locate and blissfully drown in your wine glass on a warm summer evening, especially since its flight path seems to be so erratic? Mark Frye at the University of California and Andy Reynolds at Rothamsted Research in the United Kingdom have been pondering this very question.
