Unprecedented Shark Migration, Headbanging Woodpeckers, and the Brain’s Perception of ‘Not’

“From Metalhead Woodpeckers to Shark Named Genie: The Latest Science News Roundup with NPR’s Short Wave Podcast”

Scientists have recently conducted a study on how our brains process negation in language. Neuroscientist Arianna Zuanazzi led the study, which involved participants reading phrases with words like “not” and “really” next to adjectives like “good” or “bad.” Through neuroimaging and computer tasks, researchers found that negation does not invert meaning but rather mitigates it, leading to potential confusion in communication.

In another fascinating discovery, a shark named Genie, a 6-foot-long silky shark, made a record-breaking migration from the Galapagos Marine Reserve to halfway to Hawaii and back twice. This journey covered over 17,000 miles in a year and a half, making it the longest silky shark migration on record. Researchers named the shark after the late marine biologist Eugenie Clark, known as the “shark lady,” who dedicated her life to studying and improving the public image of sharks.

On a lighter note, researchers have observed woodpeckers exhibiting unusual behavior by drumming on metal surfaces instead of wood. Ornithologist Kevin McGowan explained that woodpeckers drum on metal to create the loudest noise possible during mating season to attract mates and mark territory. Urban woodpeckers have learned that metal surfaces produce a louder and more reverberant sound than wood, leading them to choose metal surfaces for drumming.

While the sound of woodpeckers drumming on metal surfaces may be annoying to some, there are ways to deter them without harming the birds. Scare tactics such as recordings of screeching hawks or physical deterrents like balloons or pinwheels can help discourage woodpeckers from drumming on metal surfaces. Overall, these scientific discoveries shed light on the fascinating behaviors and communication patterns of animals in their natural habitats.
