Collecting nectar from a variety of flowers blooming in the UC Botanical Garden, biologists found low levels of alcohol in nearly all of them.

Recent ancient DNA analysis has identified domestic dogs at archaeological sites dating to the Late Upper Paleolithic, roughly 16,000 to 14,000 years ago. This discovery pushes back the earliest confirmed genetic record of dog domestication by approximately 5,000 years, firmly placing their emergence prior to the advent of agriculture.
