If you live in the UK or Ireland, write about science, and have not been paid for that work, then you are eligible to apply for the Wellcome Trust's Science Writing Prize. The Prize is aimed at fostering high quality writing among science communicators who are either just starting their careers, or who write mainly as a hobby. Student journalists are eligible. So are people who blog about science. There are separate categories for professional scientists, and interested laypeople. The deadline is April 25.
