- You have to admire any bureaucrat who'll go dumpster diving -- into a vat of processed-food parts -- to do his job. That was part of the research a former Food and Drug Administration commissioner conducted for a new book on why people overeat.
- One eye good, two eyes unnecessary. A new kind of robot has a single "eye," eliminating the need for processing images from two "eyes" set up for stereoscopic vision. Instead, the robot "sees" via a digital camera that can process 200 frames a second in real time to understand its environment.
