Fruit flies adapt activity to 'white nights'

Evolution takes place constantly, everywhere in nature. Nevertheless, it is always exciting for biologists to observe evolution "in real time." One such opportunity for observation is currently being presented by the internal ...

Coaxing jellyfish, flies and mice to regenerate body parts

Caltech researchers have discovered certain conditions that enable different laboratory animals to regenerate amputated appendages. Upon consuming a diet high in sugar and an essential amino acid, three different species—the ...

So-called 'junk' DNA plays a key role in speciation

More than 10 percent of our genome is made up of repetitive, seemingly nonsensical stretches of genetic material called satellite DNA that do not code for any proteins. In the past, some scientists have referred to this DNA ...

Controlling carbs and fat: Learning from the fruit fly

Incretins are hormones secreted by intestinal cells that regulate pancreatic insulin and glucagon to control sugar metabolism in mammals. Although counterparts of insulin and glucagon have been identified in invertebrates, ...

Choosy female fruit flies reproduce anyway

Choosiness will lead to the best offspring. Being too choosy, however, could in the end result in no offspring at all. Female fruit flies have a solution to this dilemma.

New method preserves viable fruit fly embryos in liquid nitrogen

Cryopreservation, or the long-term storage of biomaterials at ultralow temperatures, has been used across cell types and species. However, until now, the practical cryopreservation of the fruit fly (Drosophila melanogaster)—which ...
