Down's syndrome: Paradox of a tumour repressor p21

Having three copies of chromosome 21 reduces the incidence of solid tumours in people with Down's syndrome. Studies in mice provide clues to why, and highlight a complex gene–function relationship.

Magnetism: Freedom for the poles p22

Magnetic poles always come in twos, a north and a south. That received wisdom has not stopped physicists from searching for 'monopoles' in accelerators and cosmic rays. Theory now indicates a better place to look.

Aquaculture: The price of lice p23

Wild salmon stocks in Canadian coastal waters are being severely affected by parasites from fish farms. So intense are these infestations that some populations of salmon are at risk of extinction.

Neuroscience: Love hangover p24

In many species, males have developed strategies to safeguard their genetic material from dilution by that of competing males. Fruitflies achieve this by altering the behaviour of their partners.

Carbon cycle: Sources, sinks and seasons p26

Changes in the phasing of seasonal cycles of carbon dioxide in the atmosphere mark the time when a region becomes a source or a sink of CO2. One study of such changes prompts thought-provoking conclusions.

Optics: Watch your back p27

A proposal for transporting photons invisibly between two unconnected points in space seems worthy of a Star Trek plot. But it is in principle wholly realizable, and could open up new vistas — literally.

News and Views Q&A

Astronomy: Extrasolar planets p29

Hundreds of planets are known to orbit stars other than the Sun, and unprecedented observations of their atmospheres and structures are being made. It's an invaluable opening for understanding the planets' diverse natures, the formation of our Solar System, and the possibility of habitable planets beyond our home.

Has the gamble paid off?

I was pretty nervous when I first arrived in Johannesburg for my postdoc 10 months ago, and not just because I had not set foot in Africa before agreeing to work there for a couple of years.
