Northern Ireland's top science students are being asked to compete for awards set up in memory of two of the province's most famous scientists.
A-level and GCSE students will be recognised in the scheme, set up in memory of surgeon and collector Sir Hans Sloane.
The Killyleagh man promoted inoculation against smallpox and the health-giving properties of drinking chocolate mixed with milk. A Hans Sloane medal will be presented to the student with the highest combined marks in biology, chemistry and physics at A-level.
The Sloane McClay Award for the best Northern Ireland student at GCSE also commemorates the life of Sir Allen McClay, founder of pharma firm Almac. Frances Weldon of Almac said it was fitting to commemorate Sir Allen as 2018 marked the 50th anniversary of his business.
