Diversity in food technology p473
A scientific review, farm-scale trials and extensive public consultations on genetically modified crops should pave the way for greater benefits and choice for consumers — provided that the organic movement abandons self-damaging dogmas.

Radiation: A dose of the bomb p495
Measurements of high-energy neutron exposure in Hiroshima validate estimates of the amount of radiation that survivors of the atom bomb received. Can we now predict the risks of radiation more reliably?

Global change: South dials north p496
Climate is greatly influenced by ocean circulation in the North Atlantic. But warming episodes, as glacial conditions turned into interglacials, may have been triggered by events far to the south.

Developmental biology: How to turn inside out p499
The discovery that a molecular motor of the kinesin family is involved in turning a multicellular green alga inside out might have implications for similar events in animal development.

Materials science: The road to diamond wafers p500
Diamond could rival silicon as the material of choice for the electronics industry, but has been held back by the difficulty of growing large enough wafers. This problem may now be solved.

Theoretical biology: Safeguards and spurs p501
Biological traits are buffered against genetic and environmental upset by a process called canalization. New work suggests this may be a general feature of regulatory gene networks, selected to survive gene loss.

Condensed-matter physics: Singular behaviour p504
Quantum fluctuations at absolute zero may push a system into a different phase or state. The 'quantum critical point' at which this happens in certain materials has now been probed in greater detail.

Cell biology: Moving inside membranes p505
The mechanism that inserts proteins into the membranes of cellular organelles was thought to be well understood. But studies in yeast reveal that this process is sometimes more complicated than had been suspected.

Success in an uneven market p597
Medicinal chemists are in demand more than ever before — but the vagaries of the drug-discovery market and a sluggish economy have dampened prospects temporarily, says Eugene Russo.
