If you had one hundred unlabeled DNA samples, taken from people all around the world, could you use that DNA to determine where the original donors came from?
With major improvements in genotyping technology, geneticists are now getting better and better at this game, and a recent paper in Science reports the>
Over the course of evolutionary history, Greenlanders have benefited from a genetic variation that offers an incredible advantage; two copies of a gene variant make it so that they absorb sugar differently than other people do.A new study finds that up to 3 percent of Greenland residents, based on analyzed data from>
Diabetic foot infections are a serious complications of diabetes and a leading cause of lower-limb amputation but little is known about the specific pathogens involved in these chronic foot infections, particularly E. coli, despite its frequent detection in clinical samples.A new genomic characterization of E. coli>
A small marine worm, Olavius algarvensis, is faced with a scarce food supply in the sandy sediments it lives in off the coast of Elba, so it must deal with a highly poisonous menu: it lives on carbon monoxide and hydrogen sulfide.O. algarvensis can thrive on these poisons thanks to millions of symbiotic bacteria that>
Researchers from Washington University in St. Louis and the Israeli Institute of Technology (Technion) in Haifa have developed a technique called expected mutual information (EMI)to detect the ancestry of disease genes in hybrid, or mixed, human populations.
EMI determines how a set of DNA markers is likely to>
At two months of age, infants lack language and fine motor control but their minds may be understanding how things look and figuring out to which category they belong, which would push back earlier beliefs about the foundations of visual cognition.A new study recruited 130 two-month-old infants who were placed on>
