Exploring the physics of chocolate fountains

A UCL mathematics student has found that the falling 'curtain' of chocolate in a chocolate fountain surprisingly pulls inwards rather than going straight downwards because of surface tension.

First direct sightings of low-energy positronium collisions

Positrons are the antimatter counterpart to electrons with which they annihilate releasing gamma-rays. In addition to their importance in our fundamental understanding of nature, studies of their interactions with ordinary everyday matter allow us, for example, to investigate crystal structures and to obtain functional images of human organs using the medical scan technique of positron emission tomography (PET). In many collisions of positrons with matter, positronium (Ps) is formed.
