She has reported on her results in the International Journal of Approximate Reasoning. Aristondo has analysed the change in the levels of poverty between 2005 and 2011 in 25 European countries and has indicated what caused this change—variation in the number of poor people, intensity of poverty and the differences between poor people.

Mathematics Tue, 16 Aug 2016 07:40:01 EDTnews390551490The maths behind 'impossible' never-repeating patternsRemember the graph paper you used at school, the kind that's covered with tiny squares? It's the perfect illustration of what mathematicians call a "periodic tiling of space", with shapes covering an entire area with no overlap or gap. If we moved the whole pattern by the length of a tile (translated it) or rotated it by 90 degrees, we will get the same pattern. That's because in this case, the whole tiling has the same symmetry as a single tile. But imagine tiling a bathroom with pentagons instead of squares – it's impossible, because the pentagons won't fit together without leaving gaps or overlapping one another.

The unpopular answer is, in fact, Justin Gatlin. In 2011, he ran the 100 metres in 9.45 seconds, the fastest time a human has ever run that distance, smashing Usain Bolt's best time by a massive 0.13 seconds.

If the proof turns out to be verifiable, most in the field believe it will be a truly historical event.

In their paper published in the journal Science, Austin Benson and Jure Leskovec with Stanford University and David Gleich with Purdue University outline their framework ideas and offer real life examples of ways their techniques can be applied to help understand complex networks in simpler ways. Nataša Pržulj and Noël Malod-Dognin with University College London offer an analysis of the work done by the trio in a Perspectives piece in the same journal issue.

Mathematics Thu, 23 Jun 2016 13:41:53 EDTnews385908010New statistical approach will help researchers better determine cause-effectA common problem with some scientific research, particularly projects studying human health, is that it is often difficult, if not impossible, to prove that a specific action directly causes an effect. For example, scientists have found that those who smoke cigarettes also are more likely to suffer from depression. However, scientists cannot uniquely determine whether smoking directly causes depressive symptoms, or if those with depression are more likely to cause health damaging behaviors, including smoking.

Mathematics Tue, 24 May 2016 08:09:02 EDTnews383296100How the hidden mathematics of living cells could help us decipher the brainGiven how much they can actually do, computers have a surprisingly simple basis. Indeed, the logic they use has worked so well that we have even started to think of them as analogous to the human brain. Current computers basically use two basic values – 0 (false) and 1 (true) – and apply simple operations like "and", "or" and "not" to compute with them. These operations can be combined and scaled up to represent virtually any computation.
