Neuroscientist Steve Ramirez used lasers to enter the brains of mice and edit their memories. He imagines a future where this technology might be possible in humans as well. Steve Ramirez is an assistant professor of neuroscience at Boston University. His work focuses on finding where single memories are located throughout the brain, genetically tricking the brain cells that house these memories to respond to brief pulses of light, and then using these same flickers of light to reactivate, erase, and implant memories.
No one could figure out why a North American woodpecker's feathers were changing color--until now. A northern yellow-shafted flicker with normal coloration flies out of its nesting hole. For the yellow-shafted northern flicker, "you are what you eat" has proven freakishly true. These eastern North American woodpeckers get their name from a thin vein of yellow that runs through the center of their dark feathers. In the past few decades, ornithologists have noticed some the birds' yellow feathers have mysteriously turned red.
Katie Ledecky won four gold medals and set two world records at the Olympics this summer. But on Wednesday, she had to concede what some 19-year-olds would consider an even more valuable prize -- a free waffle maker. In her appearance on The Ellen DeGeneres Show, Ledecky faced off against American Ninja Warrior's Grant McCartney in a game of "Foot Flickers." DeGeneres let both contestants know they'd be competing for a waffle maker. SEE ALSO: Make money or go to Stanford?
Trump, the trigger: Michelle Goldberg speaks with victims of sexual assault and finds that their memories, and fears, have been relentlessly stirred up by the Trump campaign. "It's as if Trump has shaken a psychic snow globe, and now flickers of half-remembered horror are floating through the atmosphere all around us," Goldberg writes.
