We are pleased to announce the election of four new leaders to the GSA Board of Directors: 2024 Vice President/2025 President Brenda Andrews Professor, University of Toronto It’s an honor to continue my association with the Society by serving as Vice President of the Board of Directors. I have broad knowledge of the ongoing activities…

Bioinformatics—a scientific discipline that aims to curate, analyze, and distribute biological data—is facing a crisis: a deluge of data is overwhelming laboratories and existing infrastructure.  Biologists, especially those working in genome sciences, have recognized the importance of big data: in just two decades, the number of genome sequences has increased 10,000-fold (from 180,000 to 1.8…

Becoming the president of a world-class university isn’t something that typically happens “by accident,” but that’s exactly how Shirley Tilghman describes it. “I did not intend to be a university president,” Tilghman says. “I probably had the steepest learning curve of any university president ever.” In 2000, Tilghman was serving as founding director of the…

Scientists generated a karyotype, chromosome-scale genome assembly, and manual genome annotation for a common ctenophore. Ctenophores—beautiful marine invertebrates also known as “comb jellies”—have long fascinated and perplexed biologists. Phylogeneticists believe that either ctenophores or sponges were the first organisms to branch off from the tree of life, making them the “sister clade” to all other…

After giving a talk in Seattle about chromosome pairing, Chao-ting (Ting) Wu boarded the redeye flight back to Boston and settled in to read a new research paper on an odd new discovery in the human genome. “It was so exciting, I had to get up and walk around on the plane,” she says. “I…

Written by members of the GSA Early Career Scientist Communication and Outreach Subcommittee: Carla Bautista Rodriguez, Université Laval; Zach Grochau-Wright, University of Arizona; Angel F. Cisneros Caballero, Université Laval Disrupting the complex and delicate balance of a genome can have devastating consequences. In humans, for example, extra copies of individual chromosomes can result in diseases,…

Improved duplex sequencing identifies spontaneous mutations in bacteria without long-term culturing. Spontaneous mutations are the driving force of evolution, yet, our ability to detect and study them can be limited to mutations that accumulate clonally. Sequencing technology often cannot identify very rare variants or discriminate between bona fide mutations and errors introduced during sample preparation.…

Machine learning and access to ever-expanding databases improves genomic prediction of human traits. In theory, a scientist could predict your height using just your genome sequence. In practice, though, this is still the stuff of science fiction. It’s not only your genes that affect height—environment also plays a role—but the larger problem is that height…

A new genome assembly for Antarctic fur seals sheds light on their historic comeback after 19th century hunting. In the late 19th century, the Antarctic fur seal was thought to be effectively extinct. After over a century of overexploitation driven by demand for the seal’s prized pelt, populations at known breeding grounds seemed to have…

The recipient of the 2018 Crow Award reveals details of flu evolution at the smallest —and largest—scales. For many viral diseases, a vaccine can provide lifelong protection. But for flu, you need a new shot every year. The influenza virus evolves so fast it presents a constantly moving target for both our immune systems and…

A new study reveals genetic changes that affect social behavior in chickens. We have a number of phrases that relate human behavior to that of chickens; for example, when you accuse someone of acting “chicken,” you’re likely calling them a coward. If someone is running around like a chicken with their head cut off, they’re…
