Sex chromosome evolution tracked in fruit fly
Fruit flies use alcohol as a drug to kill parasites
Fruit flies infected with a blood-borne parasite consume alcohol to self-medicate, a behavior that greatly increases their survival rate, an Emory University study finds.
Does promiscuity prevent extinction?
Promiscuous females may be the key to a species' survival, according to new research by the Universities of Exeter and Liverpool. Published today (25 February) in Current Biology, the study could solve the my ...
New insights into health and environmental effects of carbon nanoparticles
Carbon nanoparticles are widely used in medicine, electronics, optics, materials science and architecture, but their health and environmental impact is not fully understood.
Safe repellents that protect fruit from spotted wing Drosophila found
Insects destroy a very large fraction of the global agricultural output - nearly 40 percent. The spotted wing Drosophila (Drosophila suzukii), for example, feeds on ripening fruits. A nuisance especially in Nor ...
One simple molecule regulates sexual behavior in Drosophila
The common vinegar fly Drosophila melanogaster is a very well-studied animal. For decades, the fly has been used as a model organism in genetic research; its genome was fully sequenced in 2000. However, until ...
DNA with self-interest: Transposable element conquers new strain of fly
Transposable elements are DNA sequences that are capable of changing their genome position by cut and paste or copy and paste through the enzyme transposase. This ability can be harmful for hosts if transposable ...
Experiment reveals diet, immunity and gene links in fruit fly
A scientific finding in fruit flies on the interplay of genes, nutrition and immunity provides insights that may one day inform personalized medicine.
Microbes prevent malnutrition in fruit flies—and maybe humans, too
Microbes, small and ancient life forms, play a key role in maintaining life on Earth. As has often been pointed out, without microbes, we'd die—without us, most microbes would get along just fine.
Research accelerated with computerized system that analyzes animal videos
Studies of animal behavior have come a long way from the days when scientists followed their subjects around with pen and notepad. But although cameras have replaced clipboards, evaluating the resulting videos ...
Team develops a software able to identify and track an specific individual within a group
Researchers from the Spanish National Research Council (CSIC) have developed a software based on the discovery of some algorithms that enable the identification of each individual, therefore allowing their ...
'Breaking bad': Insect pests in the making
Of thousands of known species of Drosophila fruit flies, just one is known as a crop pest, depositing eggs inside ripening fruit so its maggots can feed and grow. New research from the University of Califo ...
Study of complete RNA collection of fruit fly uncovers unprecedented complexity
(Phys.org) —Scientists from Indiana University are part of a consortium that has described the transcriptome of the fruit fly Drosophila melanogaster in unprecedented detail, identifying thousands of new ...
New study shows a genetic link between feeding behavior and animal dispersal
New research from the University of Toronto Scarborough shows that animal dispersal is influenced by a gene associated with feeding and food search behaviours.
