Photosensitive alternative splicing of a malt fly circadian clock gene varies between northern and southern populations. Over the course of a day, most organisms undergo profound changes. Over the course of a season, the changes can be even more dramatic. For example, insects’ responses to the brisk nights and cooler days of fall and winter…

The Y chromosome has an unanticipated role in sex-biased intron retention in Drosophila. Differences between males and females in sexually dimorphic species stem in part from disparities in gene expression. This sex-biased expression can be achieved through numerous means, one of which is alternative splicing. In a recent study, Wang et al. investigated differences in one…

Guest post by Thomas Kaufman in memory of Kathy Matthews. The original Drosophila Stock Center was housed at Cal Tech in Pasadena and was established by Calvin Bridges and Alfred Sturtevant—students of Thomas Hunt Morgan. On Morgan’s and Bridges’ deaths, the responsibility for the collection fell to Sturtevant, who subsequently passed it to his student…

Monomethylated H3K27 is more than just an intermediate. We often talk about biological traits as if they’re written in our DNA, but some of them aren’t in our DNA at all—instead, they’re on it in the form of chemical tags on the histone proteins our genomic DNA is wrapped around. During development, each cell’s genome…

Don’t miss out on this year’s Annual Drosophila Research Conference; check out the fantastic lineup of invited speakers below! The conference will be held April 11–15, 2018 at the Philadelphia Marriott Downtown, covering a diversity of topics, from genetics, to molecular biology, cell biology, development, immunology, physiology, neuroscience, evolution, and more.

Take a deep dive into the latest topics in our field over lunch at the 59th Annual Drosophila Research Conference. Each discussion at the Community, Connections, & Lunch event will be moderated by established and up-and-coming community leaders, who will explore the latest scientific findings, such as presentations from the conference and hot topics in…

GSA is pleased to announce the recipients of the 2018 Victoria Finnerty Undergraduate Travel Award. This award, which honors the memory of Victoria Finnerty, supports travel costs for undergraduates engaged in research to attend the 59th Annual Drosophila Research Conference. Congratulations, undergrads! We’ll see you in Philadelphia. Leah Anderson The Ohio State University “I’m studying the binding properties…

Fruit fly mutants can sometimes be grisly. Ecdysteroid hormones control aspects of fly development, including molting and metamorphosis; because aberrations in these genes lead to embryos with a ghastly appearance, they have been collectively dubbed “Halloween genes.” In a study published in GENETICS, Uryu et al. investigated how the expression of these genes is regulated.…

Whether it’s a battle over territory or a brawl over a sports game, aggressive behavior is a hallmark of the animal kingdom. The influence genetics has on aggression is undeniable—but the process of determining the genes involved has been frustratingly slow. To better understand genetic factors involved in aggression, some researchers have turned to male…

The Genetics Society of America (GSA) is pleased to announce that Professor Mariana Wolfner of the Department of Molecular Biology and Genetics at Cornell University is the recipient of the 2018 Genetics Society of America Medal for her work on reproduction. Wolfner and her colleagues have identified proteins in the seminal fluid of fruit flies…

When a noni fruit ripens, it stinks like old cheese—or even vomit. Familiar to many in the form of expensive juices sold as health supplements, this pungent fruit is engaged in a slow-motion arms race with would-be insect pests. Fruit flies are unable to feast on noni—scientific name Morinda citrifolia—because the fruit is dosed with…
