Problem 61P BIO Surviving a Large Deceleration On July 13, 1977, while on a test drive at Britain's Silverstone racetrack, the throttle on David Purley's car stuck wide open. The resulting crash subjected Purley to the greatest "g-force" ever survived by a humanhe decelerated torn 173 km/h to zero in

The feather moss Pleurozium schreberi harbors species of symbiotic nitrogen-fixing bacteria. Scientists studying this moss in northern forests found that the percentage of the ground surface covered by the moss increased from about 5% in forests that had burned 35 to 41 years ago to about 70% in fore
