量子光学：光をその場で止める
Stopping light in its tracks p461
Using lasers and ultracold atoms, physicists have found a way to stop and start a pulse of light. This magic trick may one day be used to store data in a quantum computer.

太陽系外惑星：巨大惑星か矮星か？
Extrasolar planets: Giant giants or dwarf dwarfs? p462
An object at least 17 times the size of Jupiter, discovered orbiting a Sun-like star, has astronomers scratching their heads. Is it a giant planet or a failed star?

微生物学：O157のゲノム
Microbiology: Gastrogenomics p463
The genome of an Escherichia coli strain that is emerging as a severe threat to human health has been sequenced. Comparing it with that of a harmless strain suggests why some forms of this bacterium cause disease.
