How moon jellyfish get about
With their translucent bells, moon jellyfish (Aurelia aurita) move around the oceans in a very efficient way. Scientists have now used a mathematical model to investigate how these cnidarians manage to use their neural networks to control their locomotion even when they are injured. The results may also contribute to the optimization of underwater robots. more...
Brewing a better espresso, with a shot of math
Researchers are challenging common espresso wisdom, finding that fewer coffee beans, ground more coarsely, are the key to a drink that is cheaper to make, more consistent from shot to shot, and just as strong. more...
How human social structures emerge
What rules shaped humanity's original social networks? The earliest social networks were tightly knit cultural groups made of multiple biologically related families. That single group would then develop relationships with other cultural groups in their local area. Researchers used statistical physics and computer models common in evolutionary biology to explain the origin of common community structures documented by cultural anthropologists around the world. more...
Creating learning resources for blind students
Mathematics and science Braille textbooks are expensive and require an enormous effort to produce -- until now. A team of researchers has developed a method for easily creating textbooks in Braille, with an initial focus on math textbooks. The new process is made possible by a new authoring system which serves as a 'universal translator' for textbook formats. Based on this new method, the production of Braille textbooks will become easy, inexpensive, and widespread. more...
Mathematicians put famous Battle of Britain 'what if' scenarios to the test
Mathematicians have developed a new model to explore what the impact of changes to Luftwaffe tactics would actually have been. Their approach uses statistical modelling to calculate how the Battle might have played out if history had followed one of several alternative courses. more...
New mathematical model shows how diversity speeds consensus
Scientific literature abounds with examples of ways in which member diversity can benefit a group -- whether spider colonies' ability to forage or an industrial company's financial performance. Now, a newly published mathematical framework substantiates the seemingly counterintuitive observations made by prior scholars: interaction among dissimilar individuals can speed consensus. more...
Indeterminist physics for an open world
Classical physics is characterized by the equations describing the world. Yet our day-to-day experience is struck by this deterministic vision of the world. A physicist has been analyzing the classical mathematical language used in modern physics. He has thrown light on a contradiction between the equations that explained the phenomena and the finite world. He suggests making changes to the mathematical language to allow randomness and indeterminism to become part of classical physics. more...
