In Horvath’s latest post for Nat Geo’s Instagram, researcher Maria Josefa Verdugo holds an ice core taken in the central Arctic Ocean in order to study methane in the Arctic Ocean and atmosphere.
COVID-19's link to Alzheimer’s: Memory loss. Disorientation. Personality changes. Symptoms that plague long COVID sufferers are all too familiar to the some 6 million Americans with Alzheimer’s (like photographer Cheryle St. Onge’s mom Francis, pictured above). On today’s World Alzheimer’s Day, scientists are digging into the cause of COVID-related neurological problems—and the research could lead to better treatment for both conditions.
Equinox time: Step outside an hour before sunrise tomorrow and Friday and look east for the waning crescent moon as it glides through Leo, the lion constellation. The super bright star Regulus should be easy to spot with unaided eyes, but try using binoculars to see if you can find the giant sickle pattern of stars that mark the neck, mane, and head of the lion figure. As the northern hemisphere marks the autumn equinox tomorrow at 9:04 pm ET, the brightest overhead star for those across the mid-northern latitudes will be Deneb in the constellation Cygnus the swan.
This is the way: You don’t need a Millennium Falcon to visit the otherworldly landscapes from Star Wars film sets.
