Planetary science: Making mountains out of a moon pp36-37
The Moon's cratered surface preserves the record of impacts that occurred during the late stages of its accretion. New simulations show that a collision with a companion moon may have formed the lunar farside highlands. See Letter p.69

Twenty-five years on from its discovery, high-temperature superconductivity remains without a satisfactory explanation. The latest studies on the electronic phase diagram of copper oxide compounds reveal why this is so. See Letter p.73

Whether African savannahs had an impact on the evolution of our early ancestors has been a matter of debate. A study of carbon isotopes from ancient soils provides fresh clues. See Article p.51

Vampire bats sense infrared radiation to locate places where blood flows close to their prey's skin. At a molecular level, this ability is underpinned by the intricate redesign of an ion channel on facial nerves. See Letter p..88

Marine algae known as coccolithophores produce much of the ocean's calcium carbonate. A large survey reveals how these organisms' calcification processes and species distribution change in response to carbon dioxide levels. See Letter p.80
