Neurophysiology: Stressful pacemaking p1059
In Parkinson's disease, dopamine-secreting neurons die — perhaps because unrelenting calcium entry during spontaneous electrical activity puts them under unusual pressure.

Earth science: Silicon-enhanced core p1060
What elements, besides iron, make up Earth's core? Discrepancies in the isotopic ratios found in rocks from Earth's mantle and in undisturbed meteoritic material indicate strongly that one answer is silicon.

A carbon revolution has occurred — carbon atoms can be coaxed into several topologies to make materials with unique properties. Nanotubes are the vanguard of this innovation, and are on the cusp of commercial exploitation as the multifunctional components of the next generation of composite materials.
