NEWS & VIEWS
----------------------
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
Maria T. Zuber
doi:10.1038/476036a
http://www.nature.com/nature/journal/v476/n7358/full/476036a.html?WT.ec_id=NATURE-20110804

High-temperature superconductivity: The great quantum conundrum pp37-39
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
Paul Michael Grant
doi:10.1038/476037a
http://www.nature.com/nature/journal/v476/n7358/full/476037a.html?WT.ec_id=NATURE-20110804

Anthropology: Shades of the savannah pp39-40
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
Craig S. Feibel
doi:10.1038/476039a
http://www.nature.com/nature/journal/v476/n7358/full/476039a.html?WT.ec_id=NATURE-20110804

Neuroscience: Heat-thirsty bats pp40-41
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
M. Brock Fenton
doi:10.1038/476040a
http://www.nature.com/nature/journal/v476/n7358/full/476040a.html?WT.ec_id=NATURE-20110804

50 & 100 years ago p41
doi:10.1038/476041b
http://www.nature.com/nature/journal/v476/n7358/full/476041b.html?WT.ec_id=NATURE-20110804

Oceanography: Forecasting the rain ratio pp41-42
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
David A. Hutchins
