Ancient DNA offers new view on saber-toothed cats' past

Added: 20.10.2017 3:14 | 1 views | 0 comments

Researchers who've analyzed the complete mitochondrial genomes from ancient samples representing two species of saber-toothed cats have a new take on the animals' history over the last 50,000 years. The data suggest that the saber-toothed cats shared a common ancestor with all living cat-like species about 20 million years ago. The two saber-toothed cat species under study diverged from each other about 18 million years ago.

More sick, 1 possible death in Salmonella outbreak in Canada

Added: 19.10.2017 5:43 | 3 views | 0 comments

Canadian health officials are urging consumers to check their homes for certain frozen “Janes Pub Style” breaded chicken because DNA tests have matched Salmonella in the products to victims of a nationwide outbreak, which already may have killed one person. Consumers should not eat the products, according to a Wednesday update from the Public Health...

Duplications of noncoding DNA may have affected evolution of human-specific traits

Added: 18.10.2017 22:03 | 4 views | 0 comments

Duplications of large segments of noncoding DNA in the human genome may have contributed to the emergence of differences between humans and nonhuman primates, according to new results. Identifying these duplications, which include regulatory sequences, and their effect on traits and behavior may help scientists explain genetic contributions to human disease.
