Detecting tsunamis

Credit: Cardiff University Mathematicians have devised a way of calculating the size of a tsunami and its destructive force well in advance of it making landfall by measuring fast-moving underwater sound waves, opening up the possibility of a real-time early warning system. The sound waves, known as acoustic gravity waves (AGWs), are naturally occurring and…

Math can predict how cancer cells evolve

Cancer cells. Credit: Dr. Cecil Fox, National Cancer Institute Applied mathematics can be a powerful tool in helping predict the genesis and evolution of different types of cancers, a study from the University of Waterloo has found. The study used a form of mathematical analysis called evolutionary dynamics to look at how malignant mutations evolve…
