Computer chip, brain cells and mating frogs among winning science photos
Stunning images of microscopic brain cells, mating leaf frogs and a robot teacher are among the finalists in the Engineering and Physical Sciences Research Council Photography Competition.
The winning entry, by Diana Craik at the University of Oxford, shows a micro-fabricated chip in a quantum computer.
A photograph of neurological connections between developing brain cells, which could help stem cell research to treat Parkinson's and other neurodegenerative diseases, won second place.
