Kimura & Crow: Infinite alleles
For two weeks in the summer of 1953, Motoo Kimura enjoyed a welcome respite from loneliness and the austerity of post-war Japan. Crossing the Pacific from Yokohama to Seattle to commence PhD studies at Iowa State University, Kimura played deck golf, enjoyed full service meals, and napped to the soothing vibrations of the venerable passenger…

#TAGC16 Shorts: ancient roots of arthritis
#TAGC16 Shorts are brief summaries of presentations at The Allied Genetics Conference, a combined meeting of seven genetics research communities held July 13-17, 2016 in Orlando, Florida. Elbows, knuckles, and the other synovial joints in your body are mobile marvels of evolution. These joints allow a huge range of possible movements thanks to the presence of…

Primers: Make friends with a new model organism
We hope everyone at The Allied Genetics Conference this week will take the opportunity to attend some presentations outside their “home” genetics community. But we realize that sometimes listening to talks in a new field can feel like visiting a foreign country, with its own language, unfamiliar customs, and insider jokes. If only you had…

‘Omics’ data improves breast cancer survival prediction
Precise predictions of whether a tumor is likely to spread would help clinicians and patients choose the best course of treatment. But current methods fall short of the precision needed. New research in this month’s issue of GENETICS reveals that profiling primary tumor samples using genomic technologies can improve the accuracy of breast cancer survival predictions…

Learning & Doing: GSA Awardee Bill Wood interview in GENETICS
So much is easily accessible on the internet now, there’s no need to pack students’ heads with information; what’s important is that we teach students how to learn on their own. —William B. Wood Bill Wood has been a pioneer in the reform of science teaching. Along with his many scientific accomplishments, Wood’s leadership has been…

Fecal alchemy: Turning poop into genomics gold
When it comes to genotyping technology, poop genetics is stuck in the 1990s. While most geneticists are now awash in genome-scale data from thousands of individuals, those who depend on fecal and other non-invasively collected samples still rely on old-school, boutique panels of a dozen or so genetic markers. But feces — along with fur,…

Inbred Neanderthals left humans a genetic burden
The Neanderthal genome included harmful mutations that made the hominids around 40% less reproductively fit than modern humans, according to estimates published in the latest issue of GENETICS. Non-African humans inherited some of this genetic burden when they interbred with Neanderthals, though much of it has been lost over time. The results suggest that these harmful…

First gene linked to temperature-dependent sex determination
The sex of many reptile species is set by temperature. New research reported in the journal GENETICS identifies the first gene associated with temperature-dependent sex determination in any reptile. Variation at this gene in snapping turtles contributes to geographic differences in the way sex ratio is influenced by temperature. Understanding the genetics of sex determination…

Overly fastidious flies shed light on neurofibromatosis
Fruit flies that devote an excessive amount of time to grooming themselves could serve as a powerful tool for understanding the inherited disorder neurofibromatosis, type 1 (NF-1), report researchers in the latest issue of G3: Genes|Genomes|Genetics. NF-1 leads to the development of benign tumors in the peripheral nervous system. Common complications of NF-1…

Wine yeast genomes lack diversity
Sequencing the genomes of hundreds of strains of the wine yeast S. cerevisiae has revealed little genetic diversity and high levels of inbreeding. In many cases, yeast strains sold by different companies were almost genetically identical. The results, published in the April issue of G3: Genes|Genomes|Genetics, suggest that winemakers attempting to develop improved wine yeasts…

Nettie Stevens: Sex chromosomes and sexism
At the time of her death in 1912, Nettie Maria Stevens was a biologist of enough repute to be eulogized in the journal Science by future Nobelist Thomas Hunt Morgan and for her passing to be noted in The New York Times. In 1910 she had been listed among 1,000 leading American “men of science.”…
