The Apple Earphones with Remote and mic take the acclaimed Apple iPod Earphones and add a control capsule, located on the cable of the right earpiece, that includes a microphone and three buttons.

Participants were randomly assigned to either use green tea every day, as a beverage or capsule, or be part of "control" groups that took placebo capsules, drank a low-catechin tea or downed water.

Scientists simulated the ignition of the rocket and the in-flight moves of the capsule to test how the observation, control and communication systems at the Jiuquan Satellite Launch Center work.
