Every so often, there’s a claim that the ivory-billed woodpecker is back from the dead. Pixelated videos go viral, blurry photos make the front page, and birders flock to the woods to get a glimpse of the ghost bird.
Last week, a controversial paper claimed there’s reason to believe that the lost bird lives. The authors say they have evidence, including video footage, that the bird still flies. The paper is ruffling feathers among the birding and research community.
This debate has been going on for decades, but the American Birding Association categorizes the bird as “probably or actually extinct,” and its last verified sighting was in 1944.
So is it any different this time? And what do we make of the claims that keep cropping up?
Guest host Flora Lichtman talks all things ivory-billed with Michael Retter, editor of the magazines North American Birds and Special Issues of Birding, from the American Birding Association.
Tracking Pain In Your Brain
When you stub your toe, that pain is registered by the peripheral nervous system. It shoots off signals that travel up your spinal cord and to your brain, where the signals tell you, “Hey, your toe hurts. Take care of it.” But chronic pain—defined as lasting three months or more—is processed differently, and your nerves are constantly firing pain signals to your brain.
Chronic pain is complex, and a lot of its basics are still unknown. But a new study from this week discovered another piece of the pain puzzle: the brain signals that cause chronic pain and the region they are processed in. Researchers hope that this is the first step in developing a brain stimulation therapy that can intercept those chronic pain signals and bring relief to patients.
Guest host and SciFri director Charles Bergquist talks with lead author Dr. Prasad Shirvalkar, neurologist and associate professor at the University of California San Francisco, about this new paper.
What Can We Learn From A Woman Who Feels No Pain?
There are a select few humans that can’t feel any pain. Really.
One of those people is Jo Cameron, who didn’t experience any pain during childbirth or need any painkillers after a hip replacement. She’s also never been anxious or afraid.
Researchers have been studying Jo Cameron and her brain in an effort to better understand her sensory experience. This week, researchers published a new study that looks at the genes and mutations responsible for Jo’s pain free existence. They hope to use what they learn to come up with better pain management treatments for the rest of us.
Guest host and Science Friday Senior Producer Charles Berquist talks with Andrei Okorokov, associate professor at the Wolfson Institute for Biomedical Research at the University of College London, about this fascinating new research.
Turning To Space While Processing Grief
When astronomers Michelle Thaller and Andrew Booth met, it was love at first sight. The couple married in 1994, becoming a power couple in the world of space and physics research. In 2019, the couple received shocking news: Booth was diagnosed with cancer in the brain. He passed away within a year of his diagnosis.
The death of a partner is one of the most devastating things a person can go through. Thaller felt unmoored, and like Earth was not her planet anymore. To help her move forward, Thaller turned to the universe for solace.
Thaller speaks with guest host Flora Lichtman about how the mysteries of the universe have made processing grief a little easier, and taking space and time with a grain of salt.
