Beads of doubt: breaking the second law of thermodynamics
Scientists at the Australian National University (ANU) have carried out an experiment involving lasers and microscopic beads that disobeys the so-called Second Law of Thermodynamics, something many scientists had considered impossible. The law describess entropy: the tendency for all matter and energy in the universe to evolve toward a state of inert uniformity.
The finding has implications for nanotechnology - the design and construction of molecular machines. They may not work as expected.
It may also help scientists better understand DNA and proteins, molecules that form the basis of life and whose behaviour in some circumstances is not fully explained.
