### An algorithm that knows when you'll get bored with your favorite mobile game

Researchers have developed a new algorithm that predicts when a user will leave a mobile game. This information is useful for game studios so that they can design strategies to maintain the player's interest. more...

### Brain cell simulations show critical tipping point for swelling

When brain cells donâ€™t get enough energy, caused by a stroke or trauma, they can start swelling rapidly. New mathematical models of this mechanism show a critical tipping point: at lower energy levels, there is no way back. more...

### 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...
