This month 70 teenage girls from nineteen countries including Bulgaria, Saudi Arabia and Finland came to the University of Cambridge to participate in the inaugural European Girls' Mathematical Olympiad (EGMO).

The *Plus* office has opened in Barcelona! The weather is fine, the architecture is spectacular and everyone has been very friendly. And, importantly, the food is delicious! From the welcoming dinner with the conference organisers (and a delicious glass of port), to the focaccia de xocolata from the cafe round the corner to the pigs skin tapas we tried last night!

Today sees the launch of *The Aperiodical*, a new maths
magazine/blog aimed at people interested in mathematics who want to
read stuff. *Aperiodical* will post news stories related to maths, opinion pieces,
maths
videos, feature articles, as well as blog posts. It will also publish accounts of monthly MathsJams and host the Carnival of Mathematics, a monthly blogging carnival.

*Plus*postcards.

In our Science fiction, science fact project we asked you which question from the frontier of physics you'd most like to see answered on *Plus*. We have just closed the poll and with nearly 20% of your vote the winning question is *Does infinity exist?*.
