CT scan for molecules

Article Abstract:

Researchers at Canada's National Research Council in Ottawa have produced a three-dimensional scan of the outermost electron orbital around a nitrogen molecule. The 'shutter speed' of the imaging method is fast enough that scans might one day be taken of molecules caught in the middle of a chemical reaction.

Doubts on dinosaurs

Article Abstract:

An asteroid or comet 10 to 14 kilometers wide was believed to crash into the present-day Yucatan Peninsula 65 million years ago wiping out the dinosaurs. Most scientists consider the Chicxulub impact crater, which is 145 kilometers wide, to be the evidence of this Cretaceous-Territory extinction.
