Surprise slow electrons are produced when intense lasers hit clusters of atoms
Scientists found that relatively slow electrons are produced when intense lasers interact with small clusters of atoms, upturning current theories. Intense laser cluster interactions occur when small clusters of atoms, nanometres (billionths of a metre) in size, are struck with intense lasers. This happens, for example, when imaging biomedical samples on ultrafast timescales.

Size matters: if you are a bubble of volcanic gas
The chemical composition of gases emitted from volcanoes - which are used to monitor changes in volcanic activity - can change depending on the size of gas bubbles rising to the surface, and relate to the way in which they erupt. The results , published Geoscience, could be used to improve the forecasting of threats posed by certain volcanoes.  At first, we couldn't understand how the gases could emerge much colder than the molten lava sloshing in the lake.
