Researchers find new taste in fruit flies: carbonated water
08-29-2007 · EurekAlert!Scientists have found that fruit flies detect and are attracted to the taste of carbonated water, such as water found on rotting fruits containing yeast. This finding raises the question of whether taste in humans may be more complex than scientists have thought.

- Flies prefer fizzy drinks
08-29-2007 · EurekAlert!
Fruit flies like a splash of soda water in their drinks, according to researchers at the University of California, Berkeley. Kristin Scott and her colleagues discovered that the insect has specialized taste cells for carbonated water. This probably encourage flies to binge on food with growing microorganisms, since yeast and bacteria both produce carbon dioxide when they feast.

- 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.

- 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.

Researchers studying the fruit fly, Drosophila melanogaster, find that exposure to nutrient-derived odors can module lifespan and partially reverse the longevity-extending effects of dietary restriction.

- 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.

- 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.

03-01-2007 · EurekAlert!
For researchers who conduct studies in fruit flies, the logistics of housing and feeding the hundreds or thousands of flies needed for experiments can be daunting. To address this concern, the current issue of Cold Spring Harbor Protocols includes a series of articles for maintaining and manipulating flies in the laboratory.

- Fruit flies all aglow light the way to cancer prevention
01-14-2008 · EurekAlert!
A green glow from a fruit fly is giving researchers the green light when they are on the right path in their quest to develop compounds that help prevent cancer. The glow lets researchers know when powerful cancer-prevention signals similar to those spurred by protective chemicals in broccoli, cabbage, and other foods, have been turned on in the organism.
