Communication breakdown p545
The UK Medical Research Council seems to have alienated a sizeable minority of the researchers that it supports. Building bridges with these disaffected individuals must be a top priority for the agency's next chief executive.

There are two sides to biodefence p545
A mystery epidemic of pneumonia serves as a timely reminder that Mother Nature is the ultimate bioterrorist.

Negative results: Null and void p554
Many scientific studies produce negative results that never see the light of day. Is progress in some disciplines being hampered by researchers' tendencies to consign these data to the bin? Jonathan Knight investigates.

Holographic data storage: The light fantastic p556
A decade ago, holographic systems promised to revolutionize data storage. The early hype may have evaporated, but the technology quietly progressed, and working devices are now on the market. Mark Haw reports.

Superconductivity: Pebbles in the nodal pond p569
Rippling patterns of electron waves in a copper oxide match the expectation for a certain kind of excitation — another step towards understanding why copper oxides superconduct at far higher temperatures than other materials.

Developmental biology: How neurons avoid derailment p570
During development, neurons extend thin protrusions that must choose between alternative routes. A study of this process in fruitflies unites two previously disparate protein families.

Mathematics: Regime change in meteorology p571
Sudden transitions between large-scale atmospheric circulation patterns — kinds of 'punctuated equilibria' — have a deterministic component that can be exploited to identify preferred dynamic cycles.

Neurobiology: Dopamine as chicken and egg p573
State-of-the-art technology has allowed pulses of the neurotransmitter dopamine to be measured on a subsecond timescale in the brains of rats. It seems that dopamine both precedes and follows the pursuit of rewards.

Atomic physics: A new spin on magnetometry p574
The capability to measure small, localized magnetic fields is valuable in biology as well as physics. A new device, based on spin-polarized alkali atoms, achieves better sensitivity and resolution than before.

Nitrogen cycle: Solution to a marine mystery p575
The anammox reaction, a microbial process that was first observed in waste-water treatment plants, looks as if it may be a key player in the nitrogen cycle in certain parts of the oceans.
