The rise of doorbell cameras have become a powerful tool for law enforcement, but they also pose a risk. These same cameras can be used against them by allowing suspects to see the cops coming, possibly causing harm to them. It happened in South Florida when two FBI agents were killed by suspects who saw them coming on their Ring doorbell cam. Privacy issues also arise as millions of people are being recorded without their knowledge or consent. Drew Harwell, technology reporter at the Washington Post, joins us for more.
Next, scientists have been talking to people in their sleep and they are answering back. Researchers have been able to establish two-way communication with people while they were in a lucid dreaming state. Participants in the study were asked math questions and responded back with eye movements and facial expressions. Researchers hope that one day some sort of “dream therapy” could be possible in helping people out. Karen Konkoly, Ph.D. students at Northwestern University and one of the researchers on the project joins us for how it all works.
