Got something on your chest?

At Plus, we would love to hear what you have to say.

On our news page, you can add comments to all our news and blog articles, ask further questions arising from the stories, and engage in discussion with other Plus readers. Violently disagree with the author of an article? Here is where you can get your opinion across.

Plus is also proud to bring you the Mathematics forum on the Nature Network. The Nature Network was developed by science journal giant Nature as an online meeting place for scientists to gather, talk and find out about the latest scientific news and events. In the maths forum, you can connect with other mathematicians to ask your questions or post your news and events.

Got a burning maths question you need answering? Can't quite solve that equation? Ask all your confusing, baffling and confounding maths questions at Ask NRICH.

Happy posting.

Love maths and think you've got what it takes to be a designer? The Further Mathematics Network and Rolls-Royce plc are inviting entries for a new UK national poster competition for undergraduate and PGCE mathematics students. The academic year 2007-8 is the first year that the competition has been run, and there is a £100 prize awarded for the design of each winning poster — it is likely that two posters will be selected. The winning designs will be sent to schools and colleges around the UK, meaning that your poster may be exposed to tens of thousands of teachers, students and parents — the potential audience is over 2000 schools and colleges.

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.

Apart from that you will find the usual Editorial, Outer space, puzzle and book and film reviews.

Bacon sandwiches, drinking while pregnant, obesity — health risks are a favourite with the media. But behind the simple numbers quoted in the headlines lies a huge and sophisticated body of statistical research. We talk to Professor Sheila Bird of the Biostatistics Unit in Cambridge about her work in public health and its impact on policy, and discuss bias in pharmaceutical studies, as recently highlighted by the controversy around antidepressants.

Recent research suggests that generalists can thrive in society, even though most theories of evolution, and even Greek philosopher Plato, argue that individuals who perform specialist tasks are more likely to succeed.

Happy Valentines Day from Plus

Mathematics is the tool we use to solve our problems. But can maths uncover the secrets behind love? Given that love is a game, and mathematical game theory can be used to find the best strategies to win at games, why not try and apply maths to love?

So here, on Valentines Day, are some Plus stories from society's most lucky in love, the mathematicians:

  • Love's a gamble — Delve into the application of game theory to love. Is it really in your best interests to buy an expensive present for the object of your affection, or will they merely find your show of ostentatiousness pretentious?
  • Maths, love and man's best friend — Finding your perfect partner, it seems, is simply a mathematical process. Dr Peter Todd, of the Max Planck Institute in Munich, says that by the time you have met 12 potential partners, you have enough information to make a good choice as to who should be your life-long love.
  • 'Calculus' — Why sex is like mathematics? Because both can lead to productive results but that is not what we are thinking when we conduct it....
  • 2007 Nobel Prizes won by mathematicians — The maths behind one of last year's Nobel Prizes ensures happy marriages!
  • Symmetry, dance and sexual selection — There are not many concepts that are fundamental to both maths and sex, but symmetry is one of them. In maths the study of symmetry forms the basis of a vast field called group theory and can be exploited to understand the patterns inherent in nature and the abstract world. On the other hand, scientists have long suspected that the symmetry of a person or animal's body is an indicator of health and strength and therefore desirability as a potential mate. Does it make us more attractive?
  • And finally, does the Golden Ratio really have anything to do with beauty?
From everyone here at Plus, have a great Valentines Day and we hope all your sexy mathematical dreams come true.
