When squeezed, electrons increase their ability to move around. In compounds such as semiconductors and electrical insulators, such squeezing can dramatically change the electrical- and magnetic- properties. Now scientists have manipulated electron mobility and pinpointed the mechanism controlling the strength of magnetic interactions — and hence the material’s magnetic ordering temperature.

Scientists have found Yellowstone alga that detoxifies arsenic. The alga — a simple one-celled algae called Cyanidioschyzon — thrives in extremely toxic conditions and chemically modifies arsenic that occurs naturally around hot springs.
