Science education: Doing it for the kids p286
A few brave postdocs are mixing science with school teaching. Mark Peplow asks them what they give to, and get from, the children.

Exobiology: It's life...isn't it? p288
Scientists find it hard enough to pin down evidence of early life on our own planet. How on Earth do we plan to determine whether life exists elsewhere? John Whitfield finds out.

Population ecology: A three-player solution p299
The seemingly unpredictable 'boom and bust' of insect-pest populations will be better understood with the advent of a deceptively simple model combining field and laboratory data with earlier theories.

Imaging techniques: Seeing single spins p300
Combining the imaging power of magnetic resonance and the sensitivity of atomic force microscopy has created a hybrid technique that can resolve single spins beneath the surface of a sample.

Embryology: Plane talk p301
In mammals, is the three-dimensional body plan ingrained in the egg at or before fertilization? The answer is 'maybe, but then again maybe not'. Less invasive techniques might help to resolve matters.

Plant biology: Good neighbours p302
Plants depend on structures called stomata to regulate gas exchange with the air, and their positioning is crucial. A key factor controlling stomatal development and arrangement has now been found.

Solar physics: Hidden magnetism p304
Observations of the Hanle effect have revealed the existence of small-scale 'hidden' magnetic flux on the quiet Sun. The magnetic-energy density of this hidden flux is much larger than previously thought.

Developmental biology: Heading away from the rump p305
How does our rump come to be separated from our head, instead of being right behind our ears? Studies of the elongation of the developing embryo reveal some remarkable underlying mechanisms.
