Companies and labs generate massive amounts of data associated with everything from weather to cell phone usage to medical records, and each data set may involve hundreds of variables.

Game intelligence is not necessarily something you are born with but something you can learn, according to the authors of the article "Game Intelligence in Team Sports". Co-author and former NHL player Nicklas Lidström embodies the evidence.

This has been demonstrated by a team of mathematicians after analysing the trails of a species of Argentine ant. Studies like this could be applied to coordinate the movement of micro-robots in cleaning contaminated areas for example.

However, many surfaces still look unnatural. Whether it is skin, stone or wax – on the computer screen, all materials look alike, as if the objects had all been cut out of the same kind of opaque material. This is about to change: TU Wien (Vienna), the University of Zaragoza and the video game company Activision-Blizzard have developed a new mathematical method which makes surfaces appear much more realistic by taking into account light scattering which occurs below the surface.

The previous time of 20 days is reduced to just 5 hours under the new method. Its efficiency and methodological rigour has now led to the algorithm's incorporation in the world's most widely-used DNA-analysis software. This momentous scientific breakthrough is the work of Daniel Taliun. Today at the faculty of Computer Science of the Free University of Bolzano, he discussed his doctoral thesis in information technology, completed at the EURAC Center for Biomedicine.

The report has been published in the Ruhr-Universität's science magazine "RUBIN".

Voters and math decideMathematical ideas and tools are often used to describe aspects of large macroscopic systems. Examples abound in areas as varied as finance to psychology. In a paper published last month in the SIAM Journal on Applied Mathematics, author Fabio Bagarello proposes mathematical models to analyze political decision-making. Using a dynamical approach which accounts for interactions between political parties and their constituents, the model tries to deduce whether parties should form coalitions under various circumstances.

Like most seasons, some teams look like they will continue to dominate their competition while others may spring some surprises. This is the 18th year that NJIT Mathematical Sciences Professor and Associate Dean Bruce Bukiet has published his model's projections of how the standings should look at the end of the regular season. Over the years, Bukiet has applied mathematical analysis to compute the number of regular season games each Major League Baseball team should win. Though his expertise is in mathematical modeling (rather than baseball), his projections have consistently compared well with those of so-called experts.

Most often, those we engage with on the popular social media site are like-minded, and the ensuing electronic maelstrom of 140-character missives most often serves to reinforce, pulling us and them further along in the direction we were already trending toward—so that at the end of the day, we all tweet to the converted.

In their paper published in Proceedings of the National Academy of Sciences, the team describes how they employed mathematical models that allow for adding in randomness to catastrophe prediction models and what they found by doing so.

This question is at the heart of the so-called poverty or development trap problem. Using mathematics on open data sets researchers now present new insights into this issue, and also suggest which countries can be expected to develop faster. The paper is published in the journal Big Data.

In a new paper, Omidyar Fellow Yoav Kallus takes a small yet significant step toward answering those questions while at the same time addressing an old conjecture about what packs least well.

In order to achieve this, she programmed a mathematical tool in which all stations had to be visited at least once and where all connections had to be ridden at least once as well. Her tool eventually provided a travel plan which, despite a heavy storm, in practice would be 1 hour and 57 minutes faster than the previous record. At every station she took a picture as proof. The record attempt has been submitted to Guinness World Records, for an official mention.
