What a conventional particle accelerator needs kilometres to achieve, a compact 'plasma wakefield' accelerator has just mastered in less than a metre. So is it adieu to the era of the gargantuan mega-accelerator?

Wakes — the areas of fluid turbulence most commonly seen around the pontoons of bridges and behind moving boats — have long excited human curiosity. Leonardo da Vinci carried out some of the first scientific investigations into wakes in the early sixteenth century by placing obstacles in fast-moving water (Fig. 1
