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.

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.

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.

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.

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.
