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?

Hopes of keeping quantum mechanics 'real' have been dashed by new measurements of neutrons' quantum behaviour. Despite what our classical sensibilities require, the world is indeed fundamentally random.

Newly developed ultrathin silicon membranes can filter and separate molecules much more effectively than conventional polymer membranes. Many applications, of economic and medical significance, stand to benefit.
