Turkey freezes assets of gold trader testifying in U.S. sanctions case

World
Dec. 1 (UPI) -- Turkish prosecutors ordered the assets of gold trader Reza Zarrab to be seized Friday as he testified in Manhattan on his role in a scheme to evade U.S. sanctions against Iran.The Istanbul prosecutor's office froze Zarrab's assets as well as those of his close relatives and acquaintances, Turkey's state-run Anadolu Agency reported.The Turkish-Iranian testified in U.S. court earlier this week that he bribed Turkey's former economic minister, Mehmet Zafer Caglayan, as part of a scheme to smuggle gold for oil in violation of U.S. sanctions against Iran.Zarrab, 34, became the star witness when he agreed to cooperate with U.S. authorities to describe the details of the complex sanctions-busting operation to the court.He used markers and poster-board to draw diagrams explaining h...
Scientists witness huge cosmic crash, find origins of gold

Scientists witness huge cosmic crash, find origins of gold

Technology
It was a faint signal, but it told of one of the most violent acts in the universe, and it would soon reveal secrets of the cosmos, including how gold was created. Astronomers around the world reacted to the signal quickly, focusing telescopes located on every continent and even in orbit to a distant spot in the sky. What they witnessed in mid-August and revealed Monday was the long-ago collision of two neutron stars — a phenomenon California Institute of Technology's David H. Reitze called "the most spectacular fireworks in the universe." "When these things collide, all hell breaks loose," he said. Measurements of the light and other energy emanating from the crash have helped scientists explain how planet-killing gamma ray bursts are born, how fast the universe is expanding, and where h

Microlasers get a performance boost from a bit of gold

Science
Oct. 6 (UPI) -- Scientists have boosted the efficiency of microlasers using tiny gold particles, thus expanding the technology's real-world application possibilities.Researchers at the University of Southern California were able to create a tiny, energy-efficient frequency comb by attaching gold nanoparticles to the surface of a tiny laser.Frequency combs create a rainbow of light frequencies from a single color. The technology is used in a variety of fields, but is most often employed as a sensor capable of measuring the spectral properties of tiny targets, like potentially harmful chemicals.Today, the best commercial frequency combs are prohibitively expensive and require larges amounts of power, limiting their potential outside the lab. Scientists at USC were able to create a frequency ...
