California’s Bristlecones are the Oldest Recorded Trees in the World

Located in California’s Inyo National Forest, the most ancient tree on record—a bristlecone pine named ‘Methuselah’—is over 4,800 years old. Dendrochronologists (researchers who study the science of dating tree rings) discovered bristlecones are some of the oldest individual trees by taking core samples from trunks, which indicate the tree’s chemical, climate and growth history. This method is especially fruitful for future planning. “What we’re seeing …

Scientists Discover Female Condors Can Reproduce Without Males

Scientists in California have found that the female California condor (the largest flying bird in North America) can reproduce without males. This discovery is a culmination of work that dates back to the 1980s, when the San Diego Zoo began developing a test to determine the sex of condors. In 2021, that same test was instrumental in researchers finding a lack of male genetic material …
