From Scientific American: “Human echolocation has at times allowed people to ride bikes or play basketball despite being completely blind from a very young age. These echolocators typically perceive their environment by clicking sharply with their tongues and listening to differences in the sounds reflected off objects. Brain-imaging studies reveal that expert echolocators display responses to sound in their brain’s primary visual region, and researchers have speculated that long-term input deprivation could lead to visual regions being repurposed. “There’s been this strong tradition to think of the blind brain as different,” said Lore Thaler, a neuroscientist at Durham University in England. Thaler co-led a 2021 study showing that both blind and sighted people could learn echolocation with just 10 weeks of training.”
Tracking a serial killer: The bodies behind the walls at 10 Rillington Place
From the LRB: “On 24 March 1953, 43-year-old Beresford Wallace Brown was trying to put up a shelf on which to perch his radio while redecorating the ground-floor kitchen of 10 Rillington Place, where he was an upstairs tenant. The wall sounded hollow behind Beresford Brown’s hammer. He stripped off a sheet of wallpaper and spotted a hole in the wooden panel behind it: an alcove. He shone a torch in, and saw the white torso of a woman, her head covered. He and a fellow tenant went to a kiosk to call the police. The police found two more bodies stashed away behind the first one. All three women in the alcove, Kathleen Maloney, Rita Nelson and Hectorina Maclennan, were in their twenties. They had died between January and March.”
