Life, for most of us, ends far too soon — hence the effort by biomedical researchers to find ways to delay the aging process and extend our stay on Earth. But there’s a paradox at the heart of the science of aging: The vast majority of research focuses on fruit fl...
Many students of high school biology learned about fruit flies: the tiny, winged creatures with red or white eyes that teach us about chromosomes, DNA, and dominant and recessive genes. It’s the study of genetics at a basic level. But to understand complex gene interactions — the kind of...
As if there weren’t enough of them in the world already scientists have succeeded in cloning flies. The alike fruit flies are the first insects ever cloned says the Canadian team that created them. The question everyone asks is why anyone would want to clone flies in the first place. She...

N. MAJERUS Department of Genetics, Downing Street, Cambridge CB2 3EH, U.K. Maternally-inherited male killing microorganisms are known in a number of insect species. We here discuss the evolutionary reasons for such behaviour through examining the ongoing dynamics of these elements. In cases where...
Thomas Hunt Morganwas the first Nobel Laureate to win for research in genetics. He grew up in Lexington, Kentucky. This year, 2016, is the 150th anniversary of his birth – a notable milestone in biological science history. But it passed largely unnoticed. Nevertheless, Morgan was the first...
The flies used in the experiment were the F2 progeny of wild flies trapped in August 1980 [36], so the experiment must have been carried out sometime between October and February. Hence a wide range of temperatures would be possible. Given that we observed higher rates of polyandry at both...
True fruit flies (Diptera: Tephritidae) include over 4000 species, many of which constitute enormous threats to fruit and vegetable production worldwide. A number of Tephritidae are lekking species, forming aggregations in which males fight to defend a small territory where they court females and ...

Because handedness occurs in other species, we can study them to determine its genetic mechanism. This comparative approach underlies all model organisms; it is why, for example, we study the metabolism of fruit flies to understand the biology of deep underground mining and the genetics of chromo...
