Fact Check My Feed: Finding The Falsehoods In ‘Plandemic’ Science Friday continues to weigh the truth and sift through the seemingly never-ending stream of misleading claims about the novel coronavirus. This week, virologist Angela Rasmussen joins Ira to help us decipher the uncertainties around this week’s COVID-19 headlines. While what we know and don’t know about COVID-19 changes daily, some things are certain: Rasmussen lays out some of the many falsehoods in the viral “Plandemic” video that

Have you ever had to learn something new and repeat it over and over—until it feels like you’re doing it in your sleep? Maybe you are. In research published this week in the journal Cell Reports, scientists monitored the brain activity of two people implanted with fine grids of neural electrodes as part of a brain-computer interface study for tetraplegia: paralysis of all four limbs. With the implants and a computer model to process the signals, the study participants were able to use their thoughts

Coronavirus is still hitting the U.S. hard. And breaking down infections by race shows a striking pattern: Black, Latino, and Native American people are hit much harder than other communities. National data shows black Americans account for nearly 30% of COVID-19 deaths, despite only being 13% of the population. In New York City, the epicenter of America’s epidemic, the death rate among black and Latino residents is more than double that of white and Asian residents. Coronavirus is spreading on

The Twists And Turns Of The Evolution Of Life On Earth In an evolutionary tree, neat branches link the paths of different species back through time. As you follow the forking paths, you can trace common ancestors, winding down the trunk to see the root organism in common. Evolution in the real world is a little messier—full of dead ends and changes happening beneath the surface, even before new traits and species appear. And the research and science that gave us a better picture about how life

Navigating COVID-19 By The Numbers Ever since the first news about a new virus in China, we’ve been seeing projections, or models predicting how it might spread. But how are those models created? There’s a lot of math that goes into understanding what might come next. Ira turns to a group of scientists who make their living in crunching the numbers—the people who make mathematical models to approximate different scenarios, trying to minimize loss of life.

Over 50 pharmaceutical companies and biotech firms around the world are now racing to develop vaccines for the coronavirus responsible for COVID-19. Anthony Fauci has said that it might be possible to develop a vaccine in as quickly as 12 to 18 months—but so far, researchers still don’t know which of several approaches might be most safe and effective. Paul Offit, head of the Vaccine Education Center at Children’s Hospital of Philadelphia, says that usually, the standard time to develop a new

When you think of fungal infections, you might think athlete’s foot or maybe ringworm—itchy, irritating reactions on the skin. But other fungal diseases can cause much more serious illness. One of them is Valley Fever, caused by the soil fungus Coccidioides. In 2018, over 15,000 people were diagnosed with coccidioidomycosis, commonly known as Valley Fever, in the United States, mainly in the American West, and in parts of Mexico, and Central and South America. But the numbers could be much higher:

In 2007, Australian eco-philosopher Glenn Albrecht described this feeling as homesickness “for a home that no longer exists,” which he called “solastalgia.” Others have settled on

2020/04/07

Quarantine has been on many of our minds lately. The phrases “shelter in place” and “self-quarantine” have filled up our news, social media, and conversations since the first inklings of the coronavirus pandemic. But this is far from the first time cities and countries have used the practice of physical separation to battle the spread of disease. You might think of Mary Mallon, who many know as “Typhoid Mary.” In the early 1900s, she spent nearly 30 years in a cottage on a small island in New

During the global COVID-19 pandemic, hospitals across the country are running low on PPE—personal protective equipment. This includes masks, gowns, face shields, and other important gear to keep healthcare workers safe. These supplies are the first line of defense between healthcare workers and potentially sick patients. Cloth masks are usually only advised as a last resort for healthcare workers, but an increasing number of hospitals are seeking them out. Some hospitals, including Barnes-Jewish

Cobalt has been hoodwinking people since the day it was pried from the earth. Named after a pesky spirit from German folklore, trickery is embedded in its name. In 1940s Netherlands, cobalt lived up to its name in a big way, playing a starring role in one of the most embarrassing art swindles of the 19th century. It’s a story of duped Nazis, a shocking court testimony, and one fateful mistake. Want more Science Diction? Subscribe wherever you get your podcasts, and sign up for our

Owen was an exceptionally talented naturalist, with over 600 scientific books and papers. But perhaps his most lasting claim to fame is that he gave these fossils a name: the dinosaurs

Now, Goodall travels the world as a conservationist, advocate for animals, and United Nations Messenger of Peace. She joins guest host John Dankosky to reflect on her years of experience in the field,
