NIST Optomechanical Transducer links sound, light, radio waves.
2016-03-30 14:31:08| Industrial Newsroom - All News for Today
Published in Nature Photonics, researchers at NIST developed "piezo-optomechanical circuit" that converts signals among optical, acoustic, and radio waves. According to one of said paper's co-authors, Kartik Srinivasan, this device might enable detailed studies of interactions and foster development of phononic circuitry that can be modified with photons. "This work," said Srinivasan, "presents one platform for transducing information between different carriers."

Christian Science Monitor: For much of the United States east of the Rocky Mountains, the summer of 2012 brought a heat wave that smashed temperature records, triggered extensive crop failures, and helped fuel a powerful line of thunderstorms known as a derecho, which moved eastward out of Indiana to leave nearly 4 million customers without power as it eventually swept through the mid-Atlantic states. The heat wave and derecho accounted for more than 100 deaths. Inspired by that summer's events, a team of researchers says...

Ocean temps predict US heat waves 50 days out

ScienceDaily: The formation of a distinct pattern of sea surface temperatures in the middle of the North Pacific Ocean can predict an increased chance of summertime heat waves in the eastern half of the United States up to 50 days in advance, according to a new study led by a scientist at the National Center for Atmospheric Research (NCAR). The pattern is a contrast of warmer-than-average water butting up against cooler-than-average seas. When it appears, the odds that extreme heat will strike during a particular...
