Ancient DNA Elizabeth Pennisi
By comparing the mitochondrial genomes of 18 ancient canids with modern dogs, wolves, and coyotes, researchers conclude that dogs were domesticated first in Europe from a lineage of gray wolves that no longer exists.
Infectious Diseases Jon Cohen
Impressive gains against HIV have led to the concept of an AIDS-free world, but a San Francisco meeting maps the challenging route ahead.
Particle Physics Adrian Cho
Researchers hoped an unexpected surplus of positrons measured in space would reveal the particles behind dark matter, but new work shows the purported excess simply might not exist.
Genomics Lizzie Wade
Mexican and U.S. researchers are teaming up to study the Mexican genome, with the hope of developing new diagnostics and drugs targeted to Latin American populations.
Biomedicine Mitch Leslie
A new clinical trial is gauging whether rapamycin, a drug that increases longevity in mice, alleviates infirmities of old age in people.
