This past year was a strange one for beekeepers. According to a survey from the nonprofit Bee Informed Partnership, U.S. beekeepers lost more than 40% of their honey bee colonies between April of 2019 and April of 2020. That’s significantly more than normal.
The Bee Informed Partnership has surveyed professional and amateur beekeepers for the past 14 years to monitor how their colonies are doing. They reach more than 10% of beekeepers in the U.S., so their survey is thought to be a pretty accurate look at what’s going on across the country.
That’s why these latest results are so important—and they raise a lot of questions for honey bee researchers. Honey bees are responsible for pollinating a lot of the food grown in the U.S. If they’re in trouble, we’re in trouble.
Nathalie Steinhauer, research coordinator for the Bee Informed Partnership in College Park, Maryland, joins producer Kathleen Davis to talk about the report, and what it means for our beloved pollinators.
As coronavirus cases spike in re-opened states like Arizona, Texas, and Florida, you may be wondering how to weigh the risks of socializing—whether it’s saying yes to a socially distant barbecue, going on a date, or meeting an old friend for coffee.
Many health departments and media outlets have offered guides to being safer while out and about. But when the messages are confusing, or you’re facing a new situation, how can you apply what you know about the virus to make the best choice for you?
Ira talks to Oni Blackstock, a primary care physician and an assistant commissioner at the New York City Health Department, and Abraar Karan, a physician at Brigham and Women’s Hospital in Boston, about minimizing risk, and why an all-or-nothing approach to COVID-19 can do more harm than good.
Imagine looking at an elementary school poster that shows the alphabet, and the numbers one through 10. The letters make perfect sense to you, as do the numbers zero and one. But instead of a curvy number “2,” or the straight edges of the number “4,” all you see is a messy tangle of lines. That’s the phenomenon experienced by RFS, a man identified only by his initials for privacy reasons.
In 2011, RFS was diagnosed with a condition called corticobasal syndrome, a progressive neurodegenerative disorder. Normally, that rare condition primarily affects motor circuitry in the brain. However, RFS had an additional symptom—while he was very skilled at math, he became unable to see the written digits 2 through 9. When RFS looked at one of those numbers, he saw in its place something “very strange” that he could only describe as “visual spaghetti.” Even weirder, other images placed on top of or nearby the digits also became completely distorted.
Teresa Schubert and David Rothlein, two scientists who studied RFS’ case as graduate students, discuss what this unusual phenomenon tells us about how the human brain processes incoming visual information.
