Adaptive Zoom Riflescope Prototype Has Push-Button Magnification

razar.jpg

Sandia National Laboratories has developed a prototype Rapid Adaptive Zoom for Assault Rifles (RAZAR). At the push of a button, RAZAR can toggle between high and low magnifications, enabling users to zoom in without having to remove their eyes from their targets or their hands from their rifles. The RAZAR prototype uses a patented active optical zoom system, called “adaptive zoom.” Adaptive zoom changes the focal lengths of two or more lenses by varying the curvature of the lenses’ surfaces to provide optical zoom without changing their overall positions relative to one another, allowing the user to view either a wide-angle image or zoom in on an area of interest with a compact, low-power system.

Middle-Aged Adults Were More Susceptible to the Flu Last Year Because of a New Viral Mutation

Wistar researchers have identified a new mutation in the H1N1 influenza virus that made it easily transmitted in middle-aged adults--those who should be able to resist the viral assault--during the 2013-2014 influenza season. .
