Worried about tainted food? A new pair of "smart chopsticks" will gauge whether you can safely tuck in, said Yang Jie at The Wall Street Journal. The utensils, unveiled recently by Chinese tech giant Baidu, feature built-in sensors that "can detect oils containing unsanitary levels of contamination." Called Kuaisou, the chopsticks link to a smartphone app, which displays a "good" or "bad" reading depending on the quality of the food’s cooking oil. Baidu says Kuaisou will also measure temperature, calories, and nutritional information.
