Eron Lindenstrauss got the Fields Medal for developing tools in the area of dynamical systems and using them to crack hard problems in the seemingly unrelated area of number theory. 
Researchers have unveiled the first prototypes of robots that can
develop emotions and express them too.
If you treat these robots
well, they'll form an attachment to you, looking for hugs when they
feel sad and responding to reassuring strokes when they are
distressed. But how do you get emotions
into machines that only understand the language of maths?

Two computer geeks claim to have calculated the number pi to 5 trillion digits — on a single desktop and in record time. That's 2.3 trillion digits more than the previous world record held by the Frenchman Fabrice Bellard. 
The human genome is represented by a sequence of 3 billion As, Cs, Gs, and Ts. With such large numbers, sequencing the entire genome of a complex organism isn't just a challenge in biochemistry. It's a logistical nightmare, which can only be solved with clever algorithms. 
Helen Joyce is a former editor of Plus magazine who now works as a journalist for The Economist. In August she's off to Brazil to be the paper's Brazil Bureau Chief. In between packing and learning Portuguese she has found time to tell Plus all about her varied career and the role maths has played in it. 
One advantage of the UK voting system is that nobody could possibly fail to understand how it works. However, the disadvantages are wellknown. Differently sized constituencies mean that the party in government doesn't necessarily have the largest share of the vote. The firstpastthepost system turns the election into a twohorse race, which leaves swathes of the population unrepresented, forces tactical voting, and turns election campaigns into mudslinging contests. There are many alternative voting systems, but is there a perfect one? The answer, in a mathematical sense, is no. 
Lack of statistical detail leads to wrong conclusions 

Genomics is one of the fastest moving areas of science and Gavin Harper, a mathematician and statistician, has put himself right at its centre. He works for Oxford Nanopore Technologies, a company which is developing new technology for analysing molecules and sequencing DNA. With 75 employees from 18 different countries and all sorts of scientific backgrounds, Gavin's work environment is
nothing like the solitary paperandpencil affair traditionally associated with mathematics.
