Compound of manganese sulfide compressed in diamond anvil cell undergoes dramatic transition
As a compound of manganese sulfide is compressed in a diamond anvil cell, it undergoes dramatic transitions. In this illustration, the interaction between the manganese atomic ions (purple circles) and disulfur molecular ions (figure eights) increases from left to right until the overlap is ...This is an NSF Multimedia Gallery item.

All living things need metals to survive. At the host/pathogen interface, bacteria must acquire those metals from within. While host and microbe battle over metals like iron and manganese, not all host utilized metals are desirable for bacteria. In fact, copper is largely toxic to them; a fact that is exploited by the host. As such, bacteria devote significant ...

Fractal patterns may be key to semiconductor magnetism
A Princeton University-led team of scientists has observed electrons in a semiconductor on the brink of the metal-insulator transition for the first time. On the brink of the metal-insulator transition, the electrons in a manganese-doped gallium arsenide semiconductor are distributed across the ...This is an NSF Multimedia Gallery item.
