Brain cell regeneration helps repair learning and memory after injury

Newborn nerve cells may help heal the brain after a traumatic injury. In a study in mice, blocking the birth of new neurons hindered the mice’s ability to learn and remember a water maze after a brain injury, researchers from the University of Texas Southwestern Medical Center at Dallas report in the March 30 Journal …

The quantum singularity – doing the first thing quantumly that classical computers cannot

A beam splitter is a device, like the one depicted here, that bifurcates a beam of light. An experiment proposed by MIT researchers, which relies on beam splitters, would exploit the strange behavior of quantum particles to perform calculations that are hopelessly time consuming on conventional computers. Graphic: Christine Daniloff A new experiment would use …
