(McGill University) Researchers at The Neuro and the University of Maryland have figured out the mathematical calculations that specific neurons employ in order to inform us of our distance from an object and the 3-D velocities of moving objects and surfaces relative to ourselves.

DNA sequencing to detect genetic mutations can aid in the diagnosis and selection of treatment for cancer. Current methods of testing DNA samples, Sanger sequencing and pyrosequencing, occasionally produce complex results that can be difficult or impossible to interpret. Scientists have now developed a free software program, Pyromaker, that can more accurately identify such complex genetic mutations.

The collapse of the Soviet Union in 1992 brought an influx of Soviet mathematicians to US institutions, and those scholars' differing areas of specialization have changed the way math is studied and taught in this country, according to new research.
