A team of researchers at the University of Pennsylvania has found that it is possible to levitate very thin discs in conditions that mimic the mesosphere using laser light. In their paper published in the journal Science ...
The sky isn't falling, but scientists have found that parts of the upper atmosphere are gradually contracting in response to rising human-made greenhouse gas emissions.
