Genetic Engineers Work to Protect Wheat Crops from Deadly Pest
Currently, roughly 20 percent of humanity’s caloric intake comes from wheat. Agricultural strains, specialized for bread or pasta production, have been bred for high productivity and resistance to many agricultural…
Researchers push back the age of recoverable DNA, a major boon for the study of evolutionary history
Researchers have reconstructed an ancient genome that is 10 times as old as any retrieved so far, and they now say that DNA should be recoverable from animals that lived…
Snail genes reveal human migration to Ireland
A genetic similarity between snail fossils found in Ireland and the Eastern Pyrenees suggests humans migrated from southern Europe to Ireland 8,000 years ago. As Britain emerged from the end…
