Researchers in the U.K. and Germany have succesfully demonstrated the use of lasers to tackle radioactive waste. The researchers used a 360J laser pulse—with a duration of 0.7 picoseconds and an intensity of 5 × 1020 W/cm2—that helped form gamma rays as it ionized a gold target behind which was a sample of nuclear waste. Transmutation occurred when the gamma rays ejected a neutron from an iodine-129 nucleus to leave behind iodine 128, whose half-life is only 25 minutes, compared with 15.7 million years of iodine 129.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
