Iowa State Engineers Develop Flexible Skin That Traps Radar Waves, Cloaks Objects
2016-03-08 04:23:20| rfglobalnet Home Page
Iowa State Universityengineershave developed a new flexible, stretchable and tunable “meta-skin” that uses rows of small, liquid-metal devices to cloak an object from the sharp eyes of radar.

Congressman Lamar Smith holds hearing on gravitational waves.
2016-02-26 14:31:15| Industrial Newsroom - All News for Today
OSA commends Chairman Lamar Smith (R-TX) for holding hearing on gravitational waves and research announced by the Laser Interferometer Gravitational Wave Observatory. LIGO's discovery of gravitational waves will impact the physical sciences for years to come and much of this discovery can be attributed to the use of advanced optical systems. Discovery reaffirms the crucial role that optics and photonics play in the most innovative discoveries in science today.

Searing Heat Waves Could Become Annual Threat
2016-02-23 14:48:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: The scorching, deadly heat waves that today strike only about once every 20 years could become an annual occurrence for more than half the world if nothing is done to curb emissions of heat-trapping greenhouse gases, a new study reported Tuesday. The work, detailed in the journal Climatic Change, also points to the worst heat waves of the future being much more intense. The results jibe with other research looking at how heat waves might change as the world warms, as well as those that have found...

Searing heat waves detailed in study of future climate
2016-02-23 13:00:00| LifeSciencesWorld
[NEWS] BOULDER — Sweltering heat waves that typically strike once every 20 years could become yearly events across 60 percent of Earth's land surface by 2075, if human-produced greenhouse gas emissions continue unchecked. If stringent emissions-reductions measures are put in place, however, these extreme heat events could be reduced significantly. Even so, 18 percent of global land areas would still be subjected yearly to these intense heat waves, defined as three exceptionall…
