The oldest animal DNA ever recovered reveals mammoths’ evolution
Mammoths evolved to handle the cold over hundreds of thousands of years and North America may been home to a hybrid species, a new study finds.

Immunity to COVID-19 may persist six months or more
Even after recovery, the body continues to improve its antibody response to the coronavirus — perhaps thanks to viral bits hiding in the intestine.
