Argonne, Harvard research team probe mechanisms regulating bacterial cell division

A Midwest Center for Structural Genomics collaborative effort between Argonne and Harvard University researchers has investigated the control of certain cell division hydrolases, called amidases, required for Escherichia coli and other pathogenic bacteria cell division.

The behavior of magnetic moments in metal oxides such as layered iridium is dominated by strong spin-orbit coupling effects. In layered compounds such as Sr3Ir2O7 (shown on the left), the direction of these moments (blue arrows) is controlled at the quantum level by dipolar interactions that are akin to those of classical bar magnets. Another outcome is an unprecedented 'magnon gap' (shown at right), which was measured at the Argonne Advanced Photon Source and reveals that these underlying dipolar magnetic interactions are extremely strong.
Quantum spins mimic refrigerator magnets

Argonne researchers have identified a new design path for manipulating the orientation of an electron spin without using magnetic fields.

Scientists study bridge over troubled water

Over a hundred years ago, English aristocrat William Armstrong used electricity to build a bridge out of water. A new experiment performed at the Advanced Photon Source may shed light on the properties of the “flowing water bridge” and perhaps help resolve an old dispute about the physical nature of water.
