Research published in the New England Journal of Medicine shows an association between the average amount of chocolate each person in country eats, and the number of Nobel Prize winners that country produces. But as the author points out, an association doesn't necessarily mean that eating chocolate
Should I be worried about lead in chocolate?
Some chocolate contains lead. Is this safe? And does the ability to measure minute quantities of lead in chocolate make the product less safe? This week's Risk Bites is about the measurement conundrum -- what do you do when you can measure what's in the stuff you eat to the nth degree? It's not primarily about the risks of lead in chocolate, but if you want to find out more about this, please check the links below. [Lead Watch is a made-up app by the way -- just in case it isn't clear!] This week's Risk Bites team: David Faulkner (Script, post-production) Andrew Maynard (all the other stuff) Thanks to Mary Hall for the inspiration on using lead in chocolate as an example of the measurement conundrum.

Risk is not just a number -- it also involves how we feel about things. This week Risk Bites introduces Dr. Brian Zikmund-Fisher, who will be talking more in future videos about how we perceive and feel about risk, and what this means about the risk decisions we make. This week's Risk Bites team:
We'll be tackling the risks of nanoparticles and other particles more fully when Risk Bites launches formally in November. But until then, here's a roller-coaster ride of a video on what might be important when thinking about the risks and benefits or nanoparticles - or any other particles for that
