Further Evidence That Reality is a lot more complicated than we think it is

Physicists have succeeded in confirming one of the theoretical aspects of quantum physics: Subatomic objects switch between particle and wave states when observed, while remaining in a dual state beforehand. Now, Dr. Andrew Truscott of the Australian National University has reported the same thing in Nature Physics, but this time using a helium atom, rather than a photon.
