Global water use may outstrip supply by mid-century
Population growth could cause global demand for water to outpace supply by mid-century if current levels of consumption continue. But it wouldn't be the first time this has happened, a Duke University study finds.
A duel between mathematical models supports the reigning theory of the genetics of altruism
It isn't that often that a scientific controversy is featured in the New Yorker, but in 2012 an article titled "Kin and Kind" describing a tempest over a biological theory appeared in its pages. ...
Study shows orangutans use their hands to make their voices deeper
Wind farms perform best when the sun is out
When set up in groups, wind turbines in the front rows cast a wind shadow on those behind them, lowering their performance. These effects dissipate fastest under convective conditions, say EPFL researchers ...
Math model helps explain how conformity works
Mathematicians model fluids at the mesoscale
When it comes to boiling water—or the phenomenon of applying heat to a liquid until it transitions to a gas—is there anything left for today's scientists to study? The surprising answer is, yes, quite ...
The building blocks of the future defy logic
Wake up in the morning and stretch; your midsection narrows. Pull on a piece of plastic at separate ends; it becomes thinner. So does a rubber band. One might assume that when a force is applied along an ...
We could all be worse off because of price comparison websites
The existence of price comparison websites may be bad for consumers, research by the University of Warwick's Department of Economics has found.
Minimizing 'false positives' key to vaccinating against bovine TB
New diagnostic tests are needed to make vaccination against bovine tuberculosis (bovine TB) viable and the number of false positives from these tests must be below 15 out of every 10,000 cattle tested, according ...
Mathematical model controls a micromanipulation system more accurately
A mathematical model can improve the accuracy and repeatability of a positioning system by learning to anticipate tiny errors in its movements, show A*STAR researchers.
Decision cascades in social networks
How do people in a social network behave? How are opinions, decisions and behaviors of individuals influenced by their online networks? Can the application of math help answer these questions?
Uncovering complex network structures in nature
The global spread of Ebola is due to the complex interactions between individuals, societies, and transportation and trade networks. Understanding and building appropriate statistical and mathematical models ...
The utility of mathematical models in evolutionary biology
Despite their important role as "proof-of-concept" tests in evolutionary research, mathematical models are commonly misunderstood in the biology research community.
Research could improve nuclear power plant safety – and stop your kettle furring up
Taking inspiration from nature, researchers have created a versatile model to predict how stalagmite-like structures form in nuclear processing plants – as well as how lime scale builds up in kettles.
