When not caring for COVID-19 patients—her latest was a man with bacterial lung and blood infections superimposed on SARS-CoV-2 pneumonia—Krutika Kuppalli has been helping oversee the rollout of pandemic vaccines at the Medical University of South Carolina (MUSC), where she’s an infectious disease physician. She has also been meeting with vaccine-hesitant hospital staff, sitting on a committee that reviews all planned COVID-19 clinical trials at MUSC, applying for funding to study patients with Long COVID, and handling online harassment that has followed her numerous media appearances and two rounds of congressional testimony last summer.
Marine animals are swimming in circles, and the scientists who discovered the strange behavior don't know why.
Researchers have now observed green sea turtles, tiger sharks, penguins and Antarctic fur seals swimming in consecutive circles at a constant speed — a mystery the scientists think could be tied to the animals' ability to navigate by magnetism.
WHO report on coronavirus origins 'only scratched the surface,' scientists sayThe research team stressed that it could be months, or even years, before scientists have a clearer picture of how the pandemic started.
A joint investigation by the World Health Organization and China into the origins of the coronavirus released Tuesday offered little in the form of concrete findings about how the pandemic started — something scientists say will take months and maybe years of work.
A severe thunderstorm cloud that formed over the Pacific Ocean in 2018 reached the coldest temperatures ever recorded, according to a new study.
The very top of the storm cloud reached a bone-chilling minus 167.8 degrees Fahrenheit (minus 111 degrees Celsius), colder than any storm cloud measured before. Thunderstorms and tropical cyclones, a circular low-pressure storm, can reach very high altitudes — up to 11 miles (18 kilometers) from the ground — where the air is much cooler, according to a statement from the U.K.'s National Center for Earth Observation.
