Ultrafast, light-sensitive video cameras are needed for observing high-speed events such as shockwaves, communication between living cells and a Usain Bolt sprint. To catch such elusive moments, a…

People are always going on about the life expectancy of babies and people in general.   Now quantum states are getting their due. For the first time, scientists have succeeded in measuring and…

The Institute of Quantum Electronics, School of Electronics Engineering and Computer Science at Peking University has proposed the concept, principles and techniques of an active optical clock.…

Researchers from the University of Melbourne and Princeton University have shown for the first time that the difference in reflection of light from the Earth's land masses and oceans can be seen on…

If you haven’t the infinite ammo of the late Hunter S. Thompson or the lightning-fast trigger finger (and impressive spray radius) of a recent Vice President, it actually takes considerable skill to…

The next time an overnight snow begins to fall, take two bricks and place them side by side a few inches apart in your yard.  In the morning, the bricks will be covered with snow and barely…

Scientists are harnessing the cosmos as a scientific “instrument” in their quest to determine the makeup of the universe.   Evalyn Gates calls from the University of Chicago calls it “Einstein’s…

Demands on telescope technology are rapidly increasing as astronomers look at fainter and fainter objects in the night sky. The large amount of light collection area required to view very dim objects…

Sliced light is how we communicate now. Millions of phone calls and cable television shows per second are dispatched through fibers in the form of digital zeros and ones formed by chopping laser…

'Cloaking' devices bend electromagnetic waves, such as light, in such a way that it appears as if the cloaked object is not there. In the latest laboratory experiments by Duke researchers, a beam of…
