Sequencing quality and read have improved greatly, but new research in GENETICS asks whether assemblies match the estimated genome size for their species.

New work published in GENETICS suggests that mitochondria could have unique pathways to repair or respond to UV damage to their DNA.

Chromosome-level assembly of the North American wolverine sets a new standard for the weasel (Mustelidae) family.

Guest post by Nina Wolff pays tribute to long-standing GSA member Margaret Lieb. Margaret (Peggy) Lieb died on March 8, 2018 in South Pasadena, California at the age of 94. After attending schools in New Rochelle, NY, she graduated magna cum laude from Smith College, and subsequently studied with  H.J. Muller at Indiana University and…

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.…

When a mutation arises in an egg or sperm cell, it could be evolutionarily important. But if a mutation occurs in somatic tissue instead, the result could be cancer. Mutations in the germline and soma not only have contrasting consequences, they also arise at different rates that may reflect the balance of DNA damage and…

In the ruins of the Chernobyl Nuclear Power Plant—an area deemed unsafe for humans for the next 20,000 years after a catastrophic failure—life thrives. Fungi that reside there, along with other organisms that can survive large radiation doses, must have strategies to cope with the DNA-damaging effects of living at a meltdown site. In the…

Short-read sequencing has fueled the acceleration of genetic research But though these next-generation methods are fast and efficient, they can’t do everything well. One important area in which short-reads fall short is detecting structural variants (SV), where chunks of the genome are deleted, inserted, repeated, inverted, or in some other way shuffled around compared to…

If you’ve ever watched a procedural crime-solving show on television, you’re sure to have seen a lab tech magically produce results from a complicated assay in mere minutes. If you’re a wet lab scientist, you’ve probably found yourself wishing that “CSI technology” were real so you didn’t have to spend your whole day running PCRs…

When sharp-eyed 20-year-old Calvin Bridges entered Columbia University in 1909, the word “gene” had just been coined. At that time, the term was profoundly abstract, referring to “factors” or “conditions” that could be glimpsed only through the window of statistical analysis. Seven years later, Bridges and his colleagues had brought these mysterious factors firmly down…
