A new UC Davis study reveals previously unknown cell types in the female reproductive tract of Drosophila fruit flies. The knowledge could help in studies of fertility in general, and in managing ...

Giant sperm may be the ultimate packers. Inside male fruit flies, thousands of sperm ­— each about as long as the fruit fly itself ­— cram into sacs roughly the size of a very fine pen tip. And ...

In arriving at their breakthrough, researchers at the University of Cambridge worked with over 220,000 fruit flies during the course of six years. To hunt down the genes responsible for virgin birth ...

Fungi-eating orchids were found for the first time to offer their flowers to fungi-eating fruit flies in exchange for pollination, which is the first evidence for nursery pollination in orchids. This ...

Osaka, Japan – For many of us, when we think of microbiomes, our first thoughts are probably about the beneficial microorganisms that live in our guts. But now, researchers from Japan and US have ...

For the first time, scientists have induced facultative parthenogenesis, a form of asexual reproduction, in an animal that usually reproduces sexually. An estimated 76 percent of fruit flies can ...

The cellular biology of reproduction is often depicted as an epic journey, in which millions of intrepid sperm fight to be the first to claim the ultimate prize: the chance to fertilize the egg, which ...

Drosophila is one of the most thoroughly studied lab animals -- with the exception of the female reproductive tract. Now a team of biologists has taken the first deep look at the Drosophila uterus and ...
