Just 200 face cells are required to identify a face, the biologists say. After discovering how its features are encoded, the biologists were able to reconstruct the faces a monkey was looking at just by monitoring the pattern in which its face cells were firing. The finding needs to be confirmed in other laboratories. But, if correct, it could help understand how the brain encodes all seen objects, as well as suggesting new approaches to artificial vision. "Cracking the code for faces would definitely be a big deal," said Brad Duchaine, an expert on face recognition at Dartmouth.

Consumers are still mixed about Siri, but according to an exclusive new poll for USA TODAY, they like her more than other personal assistants.

Alphabet's self-driving car company Waymo is testing autonomous truck technology, according to BuzzFeed. Waymo confirmed to BuzzFeed its move after the outlet learned of the move through a photograph. The company said it was manually driving the vehicle on a public road to collect data. "Self-driving technology can transport people and things much more safely than we do today and reduce the thousands of trucking-related deaths each year," a Waymo spokesperson told BuzzFeed. "We're taking our eight years of experience in building self-driving hardware and software and conducting a technical exploration into how our technology can integrate into a truck."
