### A new model for capillary rise in nano-channels offers insights into improved hydraulic fracturing (fracking)

With fracking, scientists have calculated the expected level of capillary rise with the Lucas-Washburn equation, a mathematical model whose earliest parameters were first devised nearly a century ago. The challenge, however, is that that the equation has not been completely accurate in predicting the actual rise observed in nano-capillary laboratory experiments. more...

### Numerosity in humans, birds and fish based in brain's subcortex

A cognitive neuroscience, through study, has addressed basic research questions about how our brains process number and magnitude and how such processes give rise to more complex mathematical thinking, answering the question: where in the brain is numerical quantity evaluation processed? more...

### New twist on sofa problem that stumped mathematicians and furniture movers

With some help from 3-D printing, a UC Davis mathematician is trying to crack a problem that frustrates both mathematicians and furniture movers: What's the largest sofa you can fit round a corner? more...

### Mystery of how sperm swim revealed in mathematical formula

Researchers have developed a mathematical formula based on the rhythmic movement of a sperm's head and tail, which significantly reduces the complexities of understanding and predicting how sperm make the difficult journey towards fertilizing an egg. more...

### From the butterfly's wing to the tornado: Predicting turbulence

Remember the butterfly-triggers-tornado adage? Chaos theory says calculating turbulence to find out if that's true must be impossible. Now, physicists are latching onto turbulent patterns with digital optics and math. Their resulting forecasts jibe with actual turbulent flows. more...

### Mathematical modeling predicts student success, dropout rates

A researcher has used mathematical modeling to demonstrate that negative peer pressures can spread in a high-risk setting, influencing students' decisions to drop out of school. more...

### Profiting from the fight against corruption

Governments get richer when NGOs band together to fight official corruption, game theorists at HEC MontrĂ©al find. more...
