When a young gene known as sphinx is inactivated in the common fruit fly, it leads to increased male-male courtship, scientists report in the May 27, 2008, issue of the Proceedings of the National Academy of Sciences.

Fruit fly phlebotomy holds neuroscience promise

Drawing blood from a fruit fly may only be slightly easier than getting it from a proverbial stone or turnip, but success could provide substantial benefits for neuroscientists.

Researchers Create Mathematical Model of Fruit Fly Eyes

Many researchers have tried to create a mathematical model of how cells pack together to form tissue, but most models have many different complicated factors and no model is universal.

How do you know whether you are male or female?

New research published online this week in the open-access journal PLoS Biology investigates this basic and much-studied question in the fruit fly, and comes to a surprising new conclusion.

Fresh-cut washing practices can minimize food-borne illness risks

Researchers at the United States Department of Agriculture (USDA) recently examined the safety and quality of "wash techniques" used in the production of packaged produce. The study, published in the October 2007 issue of HortScience, simulated washing techniques to learn more about how industry practices affect quality and safety of pre-cut lettuce.

Tiny pest-eating insect fights fruit flies

Farmers and vineyard owners have a new weapon in their pest management arsenal. A commonly used parasitoid, or parasitic insect that kills its host, has proven to be quite effective in the control of fruit flies in vineyards.

Herbal extract found to increase lifespan

The herbal extract of a yellow-flowered mountain plant indigenous to the Arctic regions of Europe and Asia increased the lifespan of fruit fly populations, according to a University of California, Irvine study.

Flies' evasive move traced to sensory neurons

When fruit fly larvae are poked or prodded, they fold themselves up and corkscrew their bodies around, a behavior that appears to be the young insects’ equivalent of a “judo move,” say researchers reporting online on November 29th in the journal Current Biology, a publication of Cell Press.

Cold treatment opens doors for citrus exports to Japan

Citrus growers in eastern Australia now have greater access to the Japanese market as a result of research by the NSW Department of Primary Industries (DPI).

3-D fruit fly images to benefit brain research

harminka — Wed, 05 Sep 2007 01:26:17 -0500

The fragile head and brain of a fly are not easy things to examine but MRC scientists have figured out how to make it a little simpler. And they hope their research will shed light on human disease.

Flies prefer fizzy drinks

harminka — Wed, 29 Aug 2007 14:48:39 -0500

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. Yeast and bacteria both produce carbon dioxide (CO2) when they feast, and CO2 dissolves readily in water to produce seltzer or soda water.

Fruit fly research may clean up conventional impressions of biology

harminka — Thu, 19 Jul 2007 11:26:09 -0500

The metamorphosis of biology into a science offering numerically precise descriptions of nature has taken a leap forward with a Princeton team's elucidation of a key step in the development of fruit fly embryos - discoveries that could change how scientists think not just about flies, but about life in general.
