How do you create dramatic film out of mathematics? We find out with writer and director Timothy Lanzone.

Mathematics plays a central role in understanding how infectious diseases spread. This collection of articles looks at some basic concepts in epidemiology to help you understand this fascinating and important field, and set you up for further study.

Find out why the formula we use to work out conditional probabilities is true!

- We talk about a play that explores the fascinating mathematical collaboration between the mathematicians GH Hardy and Srinivasa Ramanujan.
News stories have claimed they may have — but is this true?

'Relatedness' has little to do with how much DNA is actually shared, which is confusing. If a sexually reproducing organism has a new mutation, how likely is it that it will be passed down to a given child? 50% Granchild? 25%...and so on.

For Hamilton's rule at least, it's more like how much DNA is shared between two members of a population over and above the population average - which means you can actually get negative relatedness, and that relatedness is completely contextual! So perhaps you could have a high relatedness to 2 bananas - if only you, two bananas, and lots of bacteria lived in a population together.
