The Committee on Gene Drive Research in Non-Human Organisms convened by National Academies of Sciences, Engineering, and Medicine held an information gathering meeting on October 28, 2015, to consider the Science, Ethics and Governance Considerations for Gene Drive Research.  This meeting comes as a component of a large Gene Drive study, which is set to review the…

What if we could eradicate malaria by engineering a mosquito population that doesn’t transmit the disease? What if we could control invasive species that outcompete natural populations? What if we could get rid of insecticide-resistant pests not by developing new chemical treatments, but instead by changing the population itself and driving it toward extinction? Although…

Genes to Genomes asked Dr. Carolyn (Lindy) McBride (Princeton University), a recipient of the Rosalind Franklin Award for Young Investigators, to tell us about her research and what it means to receive the award. She was recognized for her Rosalind Franklin Award along with another recipient, Dr. Maria Barna, at the 2015 American Society of Human Genetics…

The federal regulatory policy in use today for biotechnology products, known as the Coordinated Framework for the Regulation of Biotechnology, was created in 1986 through a joint effort between the U.S. Department of Agriculture (USDA), the Environmental Protection Agency (EPA), the Food and Drug Administration (FDA), the National Institutes of Health (NIH), the National Science Foundation…

GSA is proud to congratulate GENETICS author John Novembre, who was recently named a 2015 MacArthur Fellow or “MacArthur Genius.”  Novembre is a computational biologist whose research focuses on understanding human evolutionary history. His research findings have improved the field’s knowledge of human migratory patterns and demonstrated a correlation between shared ancestral geography and genetic similarity among Europeans. These…

As ancient humans spread across the globe from their evolutionary birthplace in Africa, they tended to lose a little genetic diversity at each step along the way. New settlements were probably often founded by small groups that carried only a subset of the total diversity present in their homelands. Successive rounds of this “founder effect”…

A vast number of species depend on sexual reproduction for survival. Sex facilitates adaptation and rids populations of deleterious mutations. Despite the benefits of this process, sex can be remarkably costly and disrupt already advantageous genetic combinations. Only 20% of fungal species have been observed to reproduce sexually, and a long-standing mystery for researchers is…

Mark Blaxter (Institute of Evolutionary Biology, University of Edinburgh) reports on the “Caenorhabditis Genomes Project” workshop at GSA’s recent 20th International C. elegans Meeting. Caenorhabditis elegans, affectionately referred to as “the worm,” is one of the prettiest and most informative of the model organisms. It is see-through, has a simple lifecycle and a remarkably simple anatomy,…

The sticky fruit of the date palm has a tangled history. New research in G3 explores the palm’s genetic diversity and traces its earliest cultivation to at least two distinct regions in North Africa and the Arabian Gulf. The date palm (Phoenix dactylifera) is one of the world’s oldest cultivated trees and has close ties…

Bdelloid rotifers have been veiled in mystery for decades. Despite extensive studies of this class of tiny freshwater invertebrates, no one has observed any trace of sex: no proven males, hermaphrodites, mating, or meiosis. Unlike other asexual organisms, which tend to be short-lived in evolutionary history, the apparently asexual bdelloid rotifers have managed to persist…
