This critical proof-of-concept addresses the ongoing controversy regarding the large amounts of oil found at the bottom of the Gulf of Mexico and will impact future oil slick modeling and clean-up strategies. The study is published in Environmental Engineering Science.

The difference is that men think they are much better at math than they really are. Women, on the other hand, tend to accurately estimate their arithmetic prowess, says Shane Bench of Washington State University in the U.S., leader of a study in Springer's journal Sex Roles.

Until now, the exact way in which they do this has puzzled researchers. A new study, led by the University of Bristol and published in Royal Society Open Science, found that while some are happy to slum it out in anything with a roof, others are so choosy that even the equivalent of a mansion will not satisfy them.

This is to be applauded by the scientific community as a step in the right direction, as it will produce a more scientifically literate society at a time of rapid technological change.

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.

Much of what I read and hear is couched in the language of science which to outsiders can seem little more than jargon and gibberish. But one word is rarely spoken or printed in science and that word is "proof". In fact, science has little to do with "proving" anything.

In their paper published in Proceedings of the National Academy of Sciences, the researchers describe how they studied the way long tailed crustaceans use their swimmerets and then developed a mathematical model to describe the most efficient way such swimmerets could be used to propel a creature—when compared, the real world method used by the crustaceans matched the optimized method found by the math models.

And, to the chagrin of loyal Mets fan Bukiet, New York's National League club looks to be in store for a disappointing year. Bukiet, who developed a mathematical model for calculating expected MLB win totals that was published in Operations Research, forecasts a mere 68 wins and a last-place finish for the Metropolitans.

The numbers in a matrix can represent data, and they can also represent mathematical equations. In many time-sensitive engineering applications, multiplying matrices can give quick but good approximations of much more complicated calculations.

The experts from the areas of robotics, mathematics and cognitive sciences want to study human locomotion as exactly as possible and transfer this onto technical equipment with the assistance of new mathematical processes and algorithms. The European Union is financing the three-year research project that started in October 2013 with approx. EUR 4.16 million. The scientific coordinator is Prof. Dr. Katja Mombaur from Heidelberg University.

It was a diagram of how species originate through time in a manner that, on paper, resembles a family tree. Since then, geneticists have been piecing together relationships among life's many creatures by DNA comparison to produce what is called the Tree of Life: a tree-shaped diagram of how everything on Earth is related. This type of diagram has dominated the perspective of evolutionary biologists for more than 150 years.
