Plus moved to a rolling publishing format rather than an issue based one after Issue 55 in June 2010

It's ten years since the first draft of the human genome was published and Plus is joining in the celebrations with a package on the maths of genes. We try and solve the genome puzzle, model cell suicide, and find out why DNA evidence in court isn't as straightforward as it seems. Genes aside, we assess small but lethal risks, create some fractal music, encounter a two box paradox, and find out how to win with coins and cards.

What are the chances of a monkey accidentally typing the complete works of Shakespeare? How can maths help reveal the secret of our genetic code? On what day of the week were you born? And what's a sweet spot? In this issue we reveal all this and more. Plus we return to our roots with a look at some intriguing integrals.

If you like your maths in unusual contexts, then this is the issue for you! We explore the power of origami to solve ancient (and very modern) problems, find the maths in fashion, and marvel at the complexities of church bell ringing. But it's not all fun and games, as we investigate the controversies surrounding breast screening and the maths behind drug-induced hallucinations, find out how to predict the impact of natural catastrophes, and answer some deep questions about the Universe.

If you have ever felt the need for speed, then this is the issue for you! Andy Green tells us how maths is going to help him break his own land speed record by driving a supersonic Bloodhound at 1,000mph. But if you prefer a more sedate pace, then why not try your hand at juggling, search for a Gömböc on the seashore, contemplate your bathroom floor or just gaze out at the horizon. And find out how probability can give you the winning edge, whether you are playing the markets, or the beautiful game.
This special double issue of Plus is cause for celebration: both of the endeavours of physics to understand our Universe, and of the writers of tomorrow who may help explain it. We explore the frontiers of modern physics: searching for alien life in space and exotic particles in the LHC, looking through the Hubble Space Telescope, imagining a holographic Universe, and wrestling with one of the biggest problems in modern physics. And the winners of the Plus new writers award 2009 explore the most beautiful equation of them all, explain the credit crunch, and unveil the curse of good looks. We raise a toast to mathematics and physics — to all the explorers of the new frontiers and the new writers who can take us there!
This is the 50th issue of Plus and to celebrate, we've made it especially big. We explore the incredibly life-like images generated by computers and fragile medieval frescoes, find chaos in fluid flows and prime numbers in a sieve, meet the "English Galileo" and a man who's into geeky pop, and learn about the dangers of bacon sandwiches. Plus the usual regular features including book reviews, puzzle and podcasts.
The two major events over the last couple of months have been the credit crunch and the US presidential election. We take a mathematical view of both of these, muse over the surprising effectiveness of maths when it comes to describing the world we live in, and scrutinise some mathematical philosophy. Plus the usual mix of news, reviews and podcasts.
How long will you live? How should you write down numbers? Who's your ideal partner? How good is our voting system? And what is a differential equation? These are difficult and momentous questions. This issue of Plus has some answers, along with a tour of digital art and the usual range of podcasts, news and reviews.

This is the biggest ever issue of Plus. We proudly present the winners of the Plus new writers award who explore, amongst other things, the mysteries of infinity, flight, love and Google. We also investigate the maths of tomography, catch some primes, and have a look at maths in the movies. Plus there's a choice of reviews and podcasts, as well as all the regular features of Plus.

Also in this issue...

Evolution is the main theme of this issue. With Darwin's anniversary year not too far off, we find out how to reconstruct the tree of life and how to spot the fingerprint of natural selection. We report on the rapidly melting Arctic, bound to destroy much of evolution's achievements, and explore the maths used in ice and ocean models. And we have a look at cellular automata, simple mathematical models that can evolve surprisingly complex behaviour. Plus you can learn how to best distribute money amongst your employees without evolving envy.
