Is the Universe finite or infinite? Is there infinity inside a black hole? Is space infinitely divisible or is there a shortest length? We talk to philosophers and physicists to find out.

Are there parallel universes? Universes in which, rather than reading this article, you are still asleep; in which you are happier, unhappier, richer, poorer, or even dead? The answer is "possibly". It's a controversial claim but one that has won more and more followers over the last few decades.

How do green algae manage a perfect breaststroke even though they haven't got a brain? Enter the maths of synchronisation.

We all now know about R, but sometimes it can be good to consider another number: the growth rate of an epidemic.

Mathematical models can help the nation return to (some sort of) normality.

Mathematicians are helping to develop an AI tool to help with diagnosing COVID-19 and making prognoses for infected patients.

How far can virus-carrying droplets fly in different environments — from buses to supermarkets? Maths can provide some answers.

We explore why you need to be extremely careful when combining the reproduction ratios of a disease in different settings, such as hospitals and the community.

How do people in different countries feel about the COVID-19 pandemic and the measures taken by their governments?

How do mathematical models of COVID-19 work and should we believe them? We talk to an epidemiologist, who has been working flat out to inform the government, to find out more.
