In the 18th century, German philosopher Immanuel Kant had described nebulae as “higher universes,” or, “so to speak, Milky Ways.” By the early 1900s, most astronomers thought that drawing that parallel was ridiculous. They were wrong.  https://t.co/bRSLXS4w7F

With global COVID-19 cases on the rise, finding ways to protect millions of immunocompromised people who are at high risk for severe disease is crucial. A third dose may be one option. https://t.co/yJU4EE26Fm https://t.co/7bFdSsELXo

In southern Alaska, the Arctic has been getting noticeably greener. New research shows this holds true of the north, too.

Somewhere off southeastern Japan’s coast around 3,000 years ago, a shark mauled a man to death. The victim’s comrades presumably brought the body, minus its sheared off right leg and left hand, back to land for burial.
