Fruit fly gene research may shed light on human disease processes
Those small fruit flies buzzing around your bananas are more than pests—they may be allies in a fruitful search for clues to human diseases caused when genes malfunction. view more (2007-03-28)
Gladstone scientists reveal the genetics of fat storage in cells
New research by the Gladstone Institutes of Cardiovascular Disease (GICD) and the University of California, San Francisco (UCSF), has revealed the genetic determinants of fat storage in cells, which may lead to a new understanding of and potential treatments for obesity, diabetes, and heart disease. view more (2008-05-22)
Honey bee chemoreceptors found for smell and taste
Honey bees have a much better sense of smell than fruit flies or mosquitoes, but a much worse sense of taste, according to researchers at the University of Illinois at Urbana-Champaign. view more (2006-10-26)
New paper offers key insights into how new species emerge
This year marks both the bicentennial of Charles Darwin's birth and the 150th anniversary of the publication of his seminal work "On the Origin of Species." view more (2009-02-06)
'Skinny gene' does exist, UT Southwestern researchers find
Researchers at UT Southwestern Medical Center have found that a single gene might control whether or not individuals tend to pile on fat, a discovery that may point to new ways to fight obesity and diabetes. view more (2007-09-05)
Daily alcohol use causes changes in sexual behavior, new study reveals
A team of researchers at Penn Sate has used an animal model to reveal, for the first time, a physiological basis for the effect of alcohol on male sexual behavior, including increased sexual arousal and decreased sexual inhibition. view more (2008-01-03)
Controlling body size by regulating the number of cells
Why are elephants bigger than mice? The main reason is that mice have fewer cells. Research published in Journal of Biology this week uncovers a key pathway that controls the number of cells in an animal, thereby controlling its size. Ernst Hafen and his colleagues from the University of Zürich used fruit flies to investigate the role of the... view more... (2003-08-05)
UT Southwestern researchers find gene mutation that leads to 'broken hearts'
Researchers at UT Southwestern Medical Center have identified a group of fruit fly gene mutations responsible for "broken hearts" in the embryonic stages of development, a discovery that could help identify genes that cause human heart defects. view more (2006-07-24)
Hard-wiring the fruit fly's visual system
Both vertebrate and fruit fly have so-called visual maps in the brain that represent the world they see. view more (2006-09-21)
Duke team finds compounds that prevent nerve damage
Duke University Medical Center scientists have made a significant finding that could lead to better drugs for several degenerative diseases including Huntington's disease and Alzheimer's disease. view more (2008-09-24)
Flies prefer fizzy drinks
While you may not catch a fly sipping Perrier, the insect has specialized taste cells for carbonated water that probably encourage it to binge on food with growing microorganisms. view more (2007-08-30)
Run amok enzyme causes same problems in both humans and fruit flies
An enzyme found at elevated levels in several human cancers has been linked to abnormal tumor growth in fruit flies, a discovery that provides a new model for understanding the link between stem cell biology and cancer, according to researchers at the University of Oregon. view more (2006-12-19)
Similar brain chemicals influence aggression in fruit flies and humans
Serotonin is a major signaling chemical in the brain, and it has long been thought to be involved in aggressive behavior in a wide variety of animals as well as in humans. Another brain chemical signal, neuropeptide Y (known as neuropeptide F in invertebrates), is also known to affect an array of behaviors in many species, including territoriality... view more...

Evolution of Old World fruit flies on three continents mirrors climate change
Fast-warming climate appears to be triggering genetic changes in a species of fruit fly that is native to Europe and was introduced into North and South America about 25 years ago. view more (2006-09-01)
Networking around the clock
A Brandeis University study published in Cell this week shows for the first time experimentally that the circadian cells in fruit flies function as a network that enables the insects to adapt their behavior according to seasonal changes. view more (2007-04-09)
The precise role of seminal proteins in sustaining post-mating responses in fruit flies
Successful reproduction is critical to pass genes to the next generation. In sexually reproducing organisms, sperm enter the female with seminal proteins that are vital for fertility. view more (2007-12-18)
Do fruit flies have free will?
Free will and true spontaneity exist - in fruit flies. This is what scientists report in a groundbreaking study in the May 16, 2007 issue of the open-access journal PLoS ONE. view more (2007-05-16)
Mechanism to Organize Nervous System Conserved in Evolution
A study led by University of California, San Diego biologists suggests that, contrary to the prevailing view, the process in early development that partitions the nervous system in fruit flies and vertebrates, like humans, evolved from a common ancestor. view more (2006-09-12)
Specific brain protein required for nerve cell connections to form and function
Neurons, or nerve cells, communicate with each other through contact points called synapses. When these connections are damaged, communication breaks down, causing the messages that would normally help our feet push our bike pedals or our mind locate our car keys to fall short. view more (2007-09-06)
Reverse evolution in real-time
In his book, Wonderful World, Stephen Jay Gould writes about an experiment of 'replaying life's tape', wherein one could go back in time, let the tape of life play again and see if 'the repetition looks at all like the original'. view more (2009-01-12)
