Arizona State University professor Nancy Grimm is one of the authors of a new and authoritative federal study assessing the current and anticipated domestic impacts of climate change. The report, “Global Climate Change Impacts in the United States,” was released June 16 by the U.S.
WASHINGTON -- The current policy and legal framework regulating use of cyberattack by the United States is ill-formed, undeveloped, and highly uncertain, says a new report from the National Research Council. The United States should establish clear national policy on the use of cyberattack, while also continuing to develop its technological capabilities in this area. The U.S.
A team of scientists has determined that a coral reef discovered in 1999 is the deepest reef ever found off the continental U.S., the U.S. Geological Survey (USGS) announced today. The reef lies in approximately 250 feet of water off the coast of southwest Florida on a submerged barrier-island named Pulley Ridge. It is a significant discovery that may be unique. Besides hosting the reef, Pulley Ridge survived rising sea level and erosion from waves and currents.
New Scientist says that a military attack on Iraq could see the first use of an e-bomb designed to destroy electronics but not harm people. U.S. intelligence reports that Iraq has moved much of its military infrastructure underground or beneath civilian buildings like hospitals. As such, the magazine says, the role of non-lethal and precision weapons would be a critical factor in any conflict. The U.S. reportedly has in its arsenal High Power Microwave (HPM) devices that produce an electromagnetic field so strong they can destroy electronic equipment in hardened command, control, communications and computer targets. One mechanism for achieving this sounds like something out of "Back to the Future": An explosive pumped flux generator. That device is essentially a bomb which with a combination of explosives and electronics, sends out an electromagnetic wave of up to tens of millions of Amps. By comparison, a typical lightning strike --- which can wreak plenty of damage on its own --- carries just 30,000 Amps.
