Particle Physics: Neutrons radiating decay p1014
That neutrons can be transmuted to protons, electrons and antineutrinos through the process of beta decay is old hat. That photons sometimes also get in on the act was suspected, but until now never confirmed.

Ageing: Too fast by mistake p1015
The intricate process of ageing involves numerous physiological pathways, together with genetic and environmental factors. Insight into this complex biology could come from studying a disorder that accelerates ageing.

Mathematics: Proof at a roll of the dice p1018
The PCP theorem encapsulates the idea that randomization allows the immediate verification of any mathematical proof. A simple route to this striking result was proposed earlier this year.

Structural biology: Dangerous liaisons on neurons p1019
Crystal structures show that botulinum toxins bind simultaneously to two sites on neurons. This dual interaction allows them to use a Trojan-horse strategy to enter nerve terminals, with deadly effect.
