Under Pressure

Researchers at Carnegie Institution use X-ray diffraction to determine iron's elasticity at high pressures, which could explain seismic anisotropy in the inner core. The findings suggest the inner core is close to melting and may contain additional components with low shear-wave velocities.

It's About Time: Biological Clock Research Keeps Ticking

Recent discoveries in circadian rhythms research have identified a set of probably a dozen or so proteins that regulate the biological clock in flies and mammals. These proteins share a common molecular motif called the PAS domain, which instructs them to attach to other proteins and help set the clock's time.
