They were seeking to identify the nature of the object responsible for the impact. Because noble gases collect in carbon particles, the scientists isolated the carbon in Cretaceous sediment taken from Denmark, Spain and New Zealand. To their surprise, all three samples contained carbon that had been deposited...

The mystery of his disappearance has been compounded by the suspicions of some Western scientists that the nuclear winter scenario was promoted by Moscow to give antinuclear groups in the U.S. and Europe some fresh...
