Taking probiotics might be the latest health fad, but for people with inflammatory bowel diseases, the microbiome is a more serious matter. With these autoimmune diseases, the composition of the gut microbiome can have critical health consequences. In the June issue of GENETICS, Mistry et al. use fruit flies to determine whether immune system activity…

Multiparental populations (MPPs) have brought a new era in mapping complex traits, as well as new analytical challenges. To face these challenges and encourage innovation, the GSA journals launched the ongoing Multiparental Populations series in 2014. This month’s issues of GENETICS and G3 feature a bumper 16 MPP articles, timed to celebrate a new easy-to-use…

Thanks to more than a hundred years of working with Drosophila melanogaster, geneticists have many powerful tools for precisely manipulating its genes. It has also become a model system for studying speciation and molecular evolution together with the other members of the melanogaster species group: D. simulans, D. mauritiana, D. yakuba, and D. santomea. However,…

We are pleased to announce the GSA Poster Award winners from the 58th Annual Drosophila Research Conference! Undergraduate and graduate student members of the GSA were eligible for the awards, and a hard-working team of postdocs volunteered their time as judges. Congratulations to all! Undergraduate Students 1st Place: Cezary Mikoluk Institution: Penn State Berks Poster title: The…

In the genomic era, population geneticists are flooded with molecular data on the evolution of natural populations. This deluge started in 1966 as a trickle of data from protein electrophoresis studies, including the landmark GENETICS papers published by Richard Lewontin and John Hubby. As Lewontin is honored this week at the Annual Drosophila Research Conference…

Fruit fly larvae have one goal: eat as much as possible. After the tiny worm-like larvae hatch from eggs embedded into the flesh of rotting fruit, they eat their way out. After days of gorging, they find a good spot to pupate and then emerge as adults. Fruit flies cannot grow after this transformation, however,…

The arms race between pathogens and their hosts leaves clear genetic marks: the most quickly evolving parts of host genomes often include immune genes. But are these fast-movers the exception among immune genes, or do most genes in this class bear the genetic signature of strong selection? In the January issue of GENETICS, Early et…

Don’t miss out on this year’s Annual Drosophila Research Conference: The late abstract deadline is January 23, 2017 and the early registration discount ends February 3, 2017. Check out the fantastic lineup of invited speakers below! More details of the conference are available here, including details of special events like the PI Early Career Forum,…

Each year, emergency departments in the US treat almost 700,000 people for traumatic brain injury (TBI). The outcome depends largely on the severity and location of the injury, but these aren’t the only factors. Age also plays a role, with children often recovering more fully than do adults. The patient’s diet following the injury may…

The human brain is an amazing machine powered by electricity. Carefully controlled patterns of changing electrical charges in neurons allow us to to think, move, and speak. When this system is disrupted, very bad things happen. A seizure occurs when a sudden surge of electrical activity in the brain interrupts normal functioning. Seizures are accompanied…

In Kentucky 150 years ago today, a child was born who would—with the help of a hardy inhabitant of trash cans and fruit bowls— grow up to change the world. That boy was Thomas Hunt Morgan. By the 1900s, the energetic young Morgan had become a well-respected expert investigating questions in experimental embryology and animal regeneration.…
