and that's where the f.b.i. today arrested hong minh troung. letters link him to the hoax mailings and the motive might be found in records revealing troung had a long grievance with federal law enforcement. in 2002 troung said he heard voices in his head, saying police were afterhim and beaming radar in his bod y. he is now held on a charge of sending hoaxes through the u.s. mail. no one

longer just on paper. los angeles supreme court judge ruled today the clippers would suffer a massive loss if the sail didn't go forward. at issue had been whether former nba team owner donald

to hit, but scientists are now telling us an asteroid hit the earth at an especially bad time for dinosaurs. otherwise, they say, they would still be here and we might not. here's dean reynolds. >> $66 million was a lousy time to be a dinosaur. volcanoes seemed to be erupted all the time, great seas died up and the planet's temperature fluctuated wildly. hard on the plants and the dinosaurs that at a time the plants and hard on the dinosaurs that ate the dinosaurs thattated the plants. if that wasn't bad enough, along came a six-mile-wide asteroid that smashed into the earth. >> the asteroid hit at the worst time for dinosaurs when they were specially vulnerable. >> we interviewed steve brusatte one of the authors at the field museum. >> if dinosaurs had had a few more years to cover that adversity, they may have been better equipped to deal with the astroid, maybe they would have survived and maybe mammals wouldn't have gotten their chance and we wouldn't be talking. >> brown: no time to gloat. a new study released last week that the earth is undergoing the sixth mass extension in history. don't look to the heavens to blame for this one. scientists say it's on us. while human population is rising, climate change and reckless land management have wiped out habitats for other animals and decimated their numbers. the new studies say various species of plants and animals are becoming extinct at least 1,000 times faster than before we showed up. >> dinosaurs tell us the groups that have been dominant for millions and millions of years can suddenly disappear when times go bad and i think there's a lesson in there for all of us. >> brown: if we're willing to learn it from those here before us. dean reynolds, cbs news, chicago. >> brown: and that's the "cbs evening news"
