From Gesture to Language
Like any language, the natural sign languages (henceforth: SLs) of deaf communities differ from each other in their grammars and lexicons. A growing number of studies indicates that SLs make use of the gestures of hearing speakers to build linguistic structure. This implies that variation and similarities…

Important Effect Observed in Development of Quantum Storage
Rare-earth materials are prime candidates for storing quantum information, because the undesirable interaction with their environment is extremely weak. Consequently however, this lack of interaction implies a very small response to light, making it hard to read and write data. Leiden physicists have…
