Time to cut regulations that protect only regulators p379
Researchers and their live subjects in US universities are valuably protected by some regulatory processes but pointlessly undermined by others. It is time to streamline or scrap the latter.

Parasites go the full monty p401
Energy metabolism is an essential function of life. Yet a resourceful parasite with a minimalist genome has discarded much of its metabolism, developing a unique alternative in the process.

Cosmology: The matter with density p402
Theories of how the Universe developed structure assume a similar distribution of matter in small and large structures. But observations of gas densities in galaxy clusters suggest that this is not the case.

Evolution: Tides of tolerance p403
Humans, and many other species, have a tendency to cooperate and help each other. But how does such behaviour evolve? Some new computer simulations provide a plausible answer.

Surface chemistry: Catalysis frozen in time p405
Modern microscopes are not just for imaging. In the right hands they can be used to follow and control catalytic reactions on a metal surface — one atom at a time.

Ecology: The guts of seed dispersal p406
Some plants have evolved delicious fruits to entice animals and birds into dispersing their seeds. But the seeds' dormancy and germinability are affected by which bird they pass through.

Palaeontology: On being vetulicolian p407
Some curious fossils from the Cambrian period have been grouped into a new phylum, the Vetulicolia. All of its members are extinct, and their unusual anatomy tempts evolutionary speculation.
