The electrical resistance of some manganese oxides takes a tumble when they become magnetic. Close examination confirms the interplay of conduction electrons and lattice vibrations that contributes to this effect.

The aquaporins are membrane channels that were originally identified as regulators of a cell's water balance. A member of the aquaporin family is now implicated as a central agent in controlling fat metabolism.

These smart bacteria 'photograph' a light pattern as a high-definition chemical image.
