This May Spark a Memory
Sending electrical currents through the brain from the scalp can improve elderly people's recall of words in a memory task for up to a month, according to a new study covered by Diana Kwon for Nature. Neuroscientists have been studying brain stimulation as a potential boost for memory for several years. In 2018, Jordana Cepelewicz wrote for Quanta about work that showed strategic shocks to the brain's cortex could enhance word recall.
You're Back!
Dogs really do miss their owners when they leave, according to new research. A study found that when dogs were reunited with their owner instead of a familiar non-owner, their eyes welled with happy tears, reports Ed Cara for Gizmodo. During the domestication of dogs from wolves more than 30,000 years ago, emotionally expressive traits may have evolved in dogs to help them bond with humans. Today, some scientists see hints of domesticity appearing in some wild dingoes that have a lot of human contact, as Carrie Arnold reported for Quanta in 2018. | |
