Those fruit flies are pickier than you think
On your kitchen counter, it might seem as though fruit flies will show up for just about any type of fruit you leave around for them. But when given a choice about where to lay their eggs, those flies will ...
Fruit flies with better sex lives live longer
Sex may in fact be one of the secrets to good health, youth and a longer life – at least for fruit flies – suggests a new University of Michigan study that appears in the journal Science.
A new, flying jellyfish-like machine (w/ Video)
Up, up in the sky: It's a bird! It's a plane! It's a... jellyfish? That's what researchers have built—a small vehicle whose flying motion resembles the movements of those boneless, pulsating, water-dwelling creatures.
NASA's next 'top model,' the fruit fly
NASA finds the common fruit fly—Drosophila melanogaster—quite an attractive "model," but not in the way you might think. This tiny insect is a biomedical research model that can reveal the basis for he ...
Why do fruit flies live so long?
Queen's University professor Adam Chippindale (Biology) and PhD candidate Christopher Kimber appear to have revealed an anomaly in the evolutionary theory of aging.
Edited RNA + invasive DNA add individuality
The story of why we are all so different goes well beyond the endless mixing and matching of DNA through breeding. A new study in the journal Nature Communications, for instance, reports a new molecular mechan ...
Promiscuous fruit flies fight infection by boosting immunity before sex
(Phys.org) —Female fruit flies regulate their genes before having sex to help them fight off sexually transmitted infections (STIs), researchers from our Department of Biology & Biochemistry have revealed.
Dogonauts and Persian cats: Why send animals into space?
If you believe news reports last week, Iran plans to launch a Persian cat into space in the next six months or so.
Largest, most accurate list of RNA editing sites
A research team centered at Brown University has compiled the largest and most stringently validated list of RNA editing sites in the fruit fly Drosophila melanogaster, a stalwart of biological research. The ...
Biologists confirm role of sperm competition in formation of new species
Female promiscuity—something that occurs in a majority of species, including humans—results in the ejaculates from two or more males overlapping within her reproductive tract. When this happens, sperm ...
The 'in-law effect': Male fruit flies sleep around but females keep it in the family
Male fruit flies like to have a variety of sexual partners, whereas females prefer to stick with the same mate – or move on to his brothers.
Inheritance of lifespan is sex-dependent in fruit flies
Like mother, like daughter; like father, like son. Evolutionary biologists at the universities in Bielefeld and Uppsala (Sweden) have now shown that this proverb also applies to inheriting a long life – at least for fruit ...
Master regulators of embryonic development: Humans and fruit flies have similar Hox genes
Hox genes are the master regulators of embryonic development for all animals, including humans, flies and worms. They decide what body parts go where. Not surprisingly, if something goes wrong with these genes, the results ...
Biologists uncover mechanisms for cholera toxin's deadly effects
Biologists at the University of California, San Diego have identified an underlying biochemical mechanism that helps make cholera toxin so deadly, often resulting in life-threating diarrhea that causes people to lose as much ...
