For the last 20 years we have connected our monitors to our computer systems having the confidence that upon turn-on, we could surf or create with never a consideration of whether the display would operate satisfactorily. VGA (Video Graphics Adaptor) technology enabled us to do that with CRTs as well...

An optical filter consisting of a multilayer spectral coating on a flexible membrane has been designed to be placed in front of the 200-in. (5.08-m) Hale telescope on Mt. Palomar. The filter is intended to protect the telescope against solar radiant flux and limit solar heating of the interior of the telescope dome...

Researchers from Princeton University have created an easy-to-produce material from semiconductors that has the rare ability to bend light in the opposite direction from all naturally occurring materials. This could lead to advances in high-speed communications, medical diagnostics, and detection of terrorist threats. The new...

For an estimated 10 million people worldwide who are blind due to cornea damage or disease, there may be hope in the form of an innovative artificial cornea design that reportedly overcomes the limitations of existing artificial corneas. Existing cornea implants need to be made larger to prevent excess corneal tissue from growing...
