Single Trapped Atom Captures Science Photography Competition's top prize - EPSRC website
An image of a single positively-charged strontium atom, held near motionless by electric fields, has won the overall prize in a national science photography competition, organised by the Engineering and Physical Sciences Research Council (EPSRC).

‘Single Atom in an Ion Trap’, by David Nadlinger, from the University of Oxford, shows the atom held by the fields emanating from the metal electrodes surrounding it. The distance between the small needle tips is about two millimetres.

When illuminated by a laser of the right blue-violet colour the atom absorbs and re-emits light particles sufficiently quickly for an ordinary camera to capture it in a long exposure photograph. The winning picture was taken through a window of the ultra-high vacuum chamber that houses the ion trap.

Transitioning from Google Reader to feedly
xpecting for some time: We have been working on a project called Normandy which is a feedly clone of the Google Reader API – running on Google App Engine. When Google Reader shuts down, feedly will seamlessly transition to the Normandy back end.


Excellent stuff -- I've just tried feedly and it's looking good -- in fact it may be a better UI overall anyway.
