### Mathematics meets biology to uncover unexpected biorhythms

A novel mathematical approach has uncovered that some animal cells have robust 12-hour cycles of genetic activity, in addition to circadian or 24-hour cycles. more...

### What your cell phone camera tells you about your brain

Your brain is structured to make the best possible decision given its limited resources, according to new research that unites cognitive science and information theory -- the branch of mathematics that underlies modern communications technology. more...

### Researchers resolve a major mystery in 2D material electronics

Researchers have discovered a one-size-fits-all master equation that shall pave the way towards better design of 2D material electronics. more...

### Mechanism of biological noise cancellation revealed

Researchers report how a particular biochemical signaling pathway cancels biological noise, ensuring the proper stem cell differentiation during development. The conclusions are based on a combination of mathematical modeling and genetic experiments on fruit flies. more...

### Using physics to predict crowd behavior

Electrons whizzing around each other and humans crammed together at a political rally don't seem to have much in common, but researchers are connecting the dots. They've developed a highly accurate mathematical approach to predict the behavior of crowds of living creatures, using methods originally developed to study large collections of quantum mechanically interacting electrons. more...

### Mathematics can assist cities in addressing unstructured neighborhoods

New mathematical models can help guide changes to the layout of poor urban neighborhoods to improve access to resources with minimum disruption and cost. more...

### A better way to count boreal birds

Knowing approximately how many individuals of a certain species are out there is important for bird conservation efforts, but raw data from bird surveys tends to underestimate bird abundance. Researchers have now tested a new statistical method to adjust for this and confirmed several mathematical tweaks that can produce better population estimates for species of conservation concern. more...
