### Understanding mudslides and other debris flows through mathematics

(Phys.org) —Mudslides. Landslides. Volcanic debris flows. Avalanches. Falling rocks. They can come along so suddenly that people, homes, roads and even towns are buried or destroyed without much warning. Recently, we've ...

### Computer generated math proof is too large for humans to check

(Phys.org) —A pair of mathematicians, Alexei Lisitsa and Boris Konev of the University of Liverpool, U.K., have come up with an interesting problem—if a computer produces a proof of a math problem that is too big to study, ...

### Mathematicians calculate that there are 177,147 ways to knot a tie

### New program simulates protein movements

Proteins are molecules involved in most of the biological processes that take place in our bodies. They have to move in order to fulfil many of their functions. For example, they open or close to keep and transport the molecules ...

### Generosity leads to evolutionary success, biologists show

With new insights into the classical game theory match-up known as the "Prisoner's Dilemma," University of Pennsylvania biologists offer a mathematically based explanation for why cooperation and generosity have evolved in ...

### Mathematician designs event cloaking device without using metamaterials

(Phys.org) —Miguel A. Lerma a mathematician at Northwestern University has uploaded a paper to the preprint server arXiv, in which he describes the design of an event cloaking device that doesn't require the use of metamaterials. ...

### The arithmetic of gun control

Aiming to quell heated national debate about gun control with factual answers, two UC Irvine mathematicians have designed parameters to measure how to best prevent both one-on-one killings and mass shootings in the United ...

### Questions for Heather Leslie: How can the market sustain fisheries?

Heather Leslie, assistant professor of environmental studies, says it's a mistake to assume market forces and sustainability must always be at loggerheads. In a recently published paper, Leslie and a group of researchers ...
