Battle-scarred flies help us understand the genetics of aggression
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…

Genetics Society of America honors Barbara Meyer with 2018 Thomas Hunt Morgan Medal
The Genetics Society of America (GSA) is pleased to announce that Barbara Meyer is the recipient of the 2018 Thomas Hunt Morgan Medal, which is awarded for lifetime achievement in genetics. This honor is given in recognition of her groundbreaking work on chromosome behaviors that govern gene expression, development, and heredity. Meyer’s studies of how…

Mariana Wolfner recognized with 2018 Genetics Society of America Medal
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…

A fly that thrives on a deadly diet
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…

Beyond BRCA: new players in breast cancer pathways discovered
Mutations that disrupt the gene BRCA2 dramatically increase the odds of developing breast and ovarian cancer—but such mutations aren’t enough to cause cancer on their own. To turn normal cells cancerous, some of BRCA2’s genetic interactors must also mutate. In an article recently published in GENETICS, Ding et al. sought to identify some of these genes.…

Zebrafish offer hope for understanding severe form of epilepsy
The prolonged and severe seizures suffered by those with pyridoxine-dependent epilepsy (PDE) can lead to brain dysfunction and death if not treated. Standard antiepileptic drugs are typically ineffective for people with this rare genetic disorder—instead, they need high doses of vitamin B6 in the form of pyridoxine or pyridoxal 5′-phosphate. But even with this supplementation,…

Sperm and eggs don’t always join at random
Choosing a mate is hardly random. During courtship in the diploid phase of our life cycle, we often employ elaborate rituals and biological signals to attract and assess potential mates. But after that, we usually assume that eggs and sperm choose each other randomly at fertilization. Or so says Mendel’s First Law. But sometimes, Joseph…

Benign yeast turn into filamentous pathogens in different ways
The yeast Candida albicans lives on and even inside many of us. Most of the time, its silent presence goes unnoticed, but this fungus can turn on its host, causing infections ranging in severity from annoying to life-threatening. For the yeast to become pathogenic, some of the C. albicans must transform from small, round cells…

Stressed-out worms hit the snooze button
When you catch a nasty cold, curling up in bed to sleep may be the only activity you can manage. Sleeping in response to stress isn’t a uniquely human behavior: many other animals have the same reaction, and it’s not clear why. While the circadian sleep that follows the pattern of the clock has been…

Why do so many Nobel Prizes go to scientists working on fruit flies?
As night fell, astronomer Jean Jacques d’Ortous de Mairan watched a plant’s leaves, symmetrically arranged side-by-side on a stem, clamp shut. It was 1729, and he was studying the dramatic nocturnal movement of Mimosa pudica. Strangely, he found that the plant behaved the same way even when it wasn’t exposed to natural cycles of light…

Clues to the innate drug resistance of a cocoa-fermenting pathogen
At first glance, the yeast Candida krusei seems as innocuous as microbes come: it’s used for fermenting cocoa beans and gives chocolate its pleasant aroma. But it’s increasingly being found as a pathogen in immunocompromised patients—and C. krusei infections aren’t always easy to cure. This yeast is naturally resistant to fluconazole, a first-line antifungal that’s…
