What’s new: Imagine going for dinner with a group of friends who switch in and out of different languages you don’t speak, but still being able to understand what they’re saying. This scenario is the inspiration for a new AI headphone system that translates the speech of multiple speakers simultaneously, in real time.
How it works: The system tracks the direction and vocal characteristics of each speaker, helping the person wearing the headphones to identify who is saying what in a group setting. Read the full story.

Your gut microbes might encourage criminal behavior
A few years ago, a Belgian man in his 30s drove into a lamppost. Twice. Local authorities found that his blood alcohol level was four times the legal limit. Over the space of a few years, the man was apprehended for drunk driving three times. And on all three occasions, he insisted he hadn’t been drinking.
He was telling the truth. A doctor later diagnosed auto-brewery syndrome—a rare condition in which the body makes its own alcohol. Microbes living inside the man’s body were fermenting the carbohydrates in his diet to create ethanol. Last year, he was acquitted of drunk driving.
His case, along with several other scientific studies, raises a fascinating question for microbiology, neuroscience, and the law: How much of our behavior can we blame on our microbes? Read the full story.
