Linnaeus at 300: We are family p247

Updating the tree of life needs both the skills of evolutionary biologists and the data from genome-crunchers — the two ignore each other at their peril. John Whitfield reports.

Linnaeus at 300: The species and the specious p250

For some, species are simply the things you save; but for taxonomists, the concept is much more complex. Emma Marris asks whether Linnaeus's legacy is cut out for conservation.

Linnaeus at 300: The big name hunters p253

Linnaeus in the information age p259

As we celebrate the visionary genius of Carl Linnaeus, it is time to analyse how professional taxonomy interfaces with the rest of biology and beyond. Where next for Linnaeus's heirs, asks H. C. J. Godfray?

Cell biology: Lost in mitotic translation p274

A protein called 14-3-3 inhibits the cell cycle and may act as a tumour suppressor. It now turns out that it is also involved in regulating protein synthesis from messenger RNA during cell division.

Quantum physics: Total surveillance p275

Trapped by mirrors, a photon can be monitored from birth to death by a stream of passing atoms. The technique could also be used to entangle the quantum states of many atoms — a possible boon for quantum computing.
