Using sound waves to levitate individual droplets of solutions containing pharmaceutical drugs and drying them in mid-air. Why do this? This is useful because most of the drugs on the market are either amorphous or crystalline and the crystalline form doesn't get absorbed by the body. So levitating the solution allows the drug to be made into an amorphous state (by evaporation) because if it were to touch any surface it would simply crystallize.
European Southern Observatory's Very Large Telescope Interferometer in Chile to observe the dust around the supermassive black hole at the center of the NGC 3783 galaxy, which lies tens of millions of light-years awayin the constellation Centaurus. The black hole, like many at the centers of galaxies, is gorging on a feast of mass that's fallen toward it from the surrounding area. As the dust falls in, it releases powerful radiation that can be spotted from across the universe.
