    Buying a handgun in Connecticut means waiting - lots of waiting. First comes an eight-hour safety course. Then picking up an application at a local police department. Review of the application (which includes a background check and fingerprinting) can take up to eight weeks. If approved, the state issues a temporary permit, which the buyer trades in at state police headquarters for a permanent one. Then it’s back to the store for the gun.

    Neither a giant asteroid nor a gradual die-out can take full blame for dinosaurs’ demise. Rather, the culprit may be both, two new studies suggest. Tens of millions of years before the asteroid delivered its killer blow some 66 million years ago, the number of dinosaur species had already begun to drop, researchers report. But not all dino groups were in decline.
