Particle Physics: The first axion? p31

For almost 30 years, the hunt has been on for a ghostly particle proposed to plug a gap in the standard model of particle physics. The detection of a tiny optical effect might be the first positive sighting.

Cell biology: Divining cancer cell weaknesses p32

Tumour cells tend to carry many gene mutations, but at a potential cost to their overall fitness. Studying the interactions between genes on a large scale could be a way of identifying the chinks in the tumour cell armour.

Planetary Science: A new spin on Saturn p34

Measuring the rotation of a gaseous planet is no easy task. For Saturn, do observations of its magnetic field — which indicate that it is spinning more slowly than thought — mark a revolution in our understanding?

Molecular biology: Chromosome guardians on duty p35

Curiously, in cell division the proper separation of chromosomes into daughter cells needs set periods when they are stuck together. So how do they come apart at the right time and place? Their 'guardian spirits' intercede.
