Changing where the polyA tail is added to an mRNA transcript can fine-tune the tissue-specific expression of many genes, reports a Caenorhabditis elegans study published...


Fascinating discoveries sometimes emerge from the most daunting of experimental roadblocks. Designed to generate over 1,000 recombinant inbred mice lines for genetic mapping, the Collaborative...


Two highly similar genes that contribute to drug resistance in a pathogenic yeast have been co-evolving as tandem duplicates for the past 134 million years—while...


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...


In 1997, Ahna Skop approached her graduate advisor, John G. White, about adding a worm-themed art show to the International C. elegans Conference he was...


Constant mutation and shaping by natural selection can make the once-identical genomes of isolated populations of organisms very different from one another. This genetic divergence...


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...


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...


When geneticist Rob Unckless took his son to Lego Club at the local library, he was not expecting to start a new collaboration. The result...


Despite being covered by a massive, permanent ice sheet, Greenland has been continuously inhabited by humans for over a thousand years. Most modern Greenlanders are...
