Platelets are vital for normal healing in the body, but if they clot in your arteries it can lead to a stroke or heart attack.
These small blood cells are important and clot to stop bleeding.
Research from Anglia Ruskin University, funded by the British Heart Foundation, is trying to understand what causes platelets to clot.
In the medical community it is well known that calcium has a key role in platelet activation, but biologist Nicholas Pugh thinks the metal ion zinc could be just as, if not more, important.
Join Nicholas in this talk exploring the 10-day life cycle of a platelet and the controversial research that could just lead to some fascinating discoveries in understanding these amazing little cells.
