Answer to Question 1

Titan, Europa, Ganymede, and Enceladus

Answer to Question 2

Because the planet passes directly in front of its star, it blocks some of the star's light. The more light that is blocked, the bigger the planet must be, so by measuring how much of the star's light is lost during such transits we can learn the planet's diameter. The time between transits reveals the planet's period, the size of its orbit and possibly its mass. Combining the mass and size of the planet can yield its density.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
