Scientists in Japan grew new mouse teeth from stem cells, reports the Times of India, paving the way for replacement human choppers somewhere down the line. The team pointed out that the new teeth were good for eating and sensitive to pain. At The Awl, Alex Balk remarks: "If they could knock them all out and put in a whole new model I'd be the first one to sign up for the procedure. (I assume they'd put me under for that, which, you know, bonus.) But hold up a second: "sensitive to pain"? WHY ON EARTH WOULD YOU WANT THAT?"
