More of Isaac Asimov's weekly science columns for the Los Angeles Times and those his wife, Janet, wrote during his illness and after his death in April 1992. The Asimovs discuss how close we are to producing life in a lab, the latest revelations about dinosaur extinction, recent startling sightings of planets and stars, if we can establish colonies on Mars, if computer intelligence can ever surpass human intelligence, and the gravest dangers to our environment.
