This chapter delves into connecting tiny songbirds' memories to barcodes and its implications for human memory. It then shifts to discussing a new robotic face named 'emo' that learns to smile by observing humans, exploring the complexities of human-robot interaction and the uncanny valley phenomenon.
Tiny, black-capped chickadees have big memories. They stash food in hundreds to thousands of locations in the wild – and then come back to these stashes when other food sources are low. Now, researchers at
Columbia University's Zuckerman Institute think neural activity that works like a barcode may be to thank for this impressive feat — and that it might be a clue for how memories work across species.
