What is a scientific model and what is it good for? As a prelude to talking about dose-response models on Risk Bites, this week's video is a primer on models -- what they are, and why they are useful. This is part of a series of Risk Bites videos that tackle dose response and response models. Ch
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.

A California judge is requiring cancer warning labels on coffee. So we thought we’d take look at some of the other highly improbable risks associated with your cup of joe. We love a good cup of coffee at Risk Bites. So we were rather dismayed to discover that California judge William le Jeunesse ha
