Astronomy: The heavens at your fingertips p262
A small but growing group of astronomers wants to put the night sky on the Internet. But will staring at a computer screen ever replace peering through a telescope? Geoff Brumfiel logs on.

Reproductive immunology: Immunity's pregnant pause p265
If we can understand why a woman's body does not reject her fetus, it could help us to treat infertility and prevent problems in pregnancy. Helen Pearson reports.

惑星科学：小惑星が衝突すると
Planetary science: Intermediate impact factors p273
No statistical documentation of objects of a certain size that enter Earth's atmosphere has hitherto been available. Analysis of data from US government satellites has bridged the gap.

発生生物学：大腸の形成
Developmental biology: Colon construction p274
It is no mean feat for organisms to make and maintain their organs. The complex cellular and molecular processes involved are illustrated by two studies of the proteins that participate in producing a colon.

材料科学：レーザー光と結晶生成
Materials chemistry: Crystals in a flash p277
If laser light is shone on a solution, the crystal structure that forms depends on the light polarization, and the more intense the laser, the greater the probability of crystal nucleation. The challenge now is to work out why this is.

分子進化：生命体を立ち上げる
Molecular evolution: Booting up life p278
A key question about evolution is how the first informational molecules — thought to be an early form of life — could generate efficient self-replication machinery. The problem is tackled in new computer simulations.

Earth science: Ancient mantle in a modern plume p281
Osmium isotopes record evidence for 2.5-billion-year-old mantle beneath the Azores. The origin of this ancient mantle has implications for the nature and timescale of mantle convection.
