Photographing Innerspaces

Makarand writes "In the past few days photographic techniques for recording phenomena at the molecular and atomic levels have been reported. Prepare to be amazed! (1) Scientists at UCLA were able to eavesdrop on cellular conversations between proteins. (2) Scientists at the University of Buffalo recorded on videotape and in real time a molecule of a particular DNA motor protein in the process of "unzipping" a double strand of bacterial DNA. A Quicktime movie is also available here. (3) Lastly, using ultrafast flash photography, scientists at the Vienna University of Technology (Austria), could for the first time ask Electrons to say "Cheese!". They could track the motion of electrons deep within atoms."
