Experiments suggest the particles that cover the surface of Saturn's moon, Titan, are 'electrically charged.' When the wind blows hard enough, Titan's non-silicate granules get kicked up and start to hop in a motion. As they collide, they become frictionally charged, like a balloon rubbing against your hair, and clump together in a way not observed for sand dune grains on Earth -- they become resistant to further motion.

Drugs containing gold have been used for centuries to treat conditions like rheumatoid arthritis. In addition, they might be effective against cancer and HIV. One mechanism by which they work could occur because gold ions force the zinc ions out of zinc fingers -- looped, nucleic acid binding protein domains. American researchers have characterized such 'gold fingers' using ion mobility mass spectrometry. They identified the exact gold binding sites.

Our understanding of the world is mostly built on basic perceptions, such as that events follow each other in a well-defined order. Such definite orders are required in the macroscopic world, for which the laws of classical physics apply. However, in the quantum world orders can be ‘scrambled’. It is possible for different orders of quantum operations to coexist in a superposition. New work by a team of physicists is the first experimental quantification of such a superposition.
