• Freshwater sustainability challenges shared by Southwest and Southeast

    Twenty-five years ago, environmentalist Marc Reisner published Cadillac Desert: The American West and Its Disappearing Water, which predicted that water resources in the West would be unable to support the growing demand of cities, agriculture, new research offers new support for most of Reisner’s conclusions, using data and methods unavailable to him in 1986

  • Safety concerns remain about Westinghouse AP1000 reactor design

    The United States and the United Kingdom are yet to approve the latest reactor design from Westinghouse; regulators in both countries are not convinced that the reactor can effectively withstand man-made or natural disasters; these concerns notwithstanding, China is pushing forward with an ambitious nuclear energy program which will see sixty AP1000 reactors built by 2010; the scope and pace of the Chinese program, and the fact that at its core is a reactor with possible design weaknesses, are a cause of more concerns

  • Flood control projects in Las Vegas

    Las Vegas is the middle of the desert, and as other desert cities it falls victims to flash flooding during the rainy season; the city has launched a $30 million project to protect local roads and businesses from floods

  • Thirteen Georgia dams could be reclassified as high risk

    The number of dams designated high risk under Georgia’s Safe Dams Act could more than double in two counties in the state, but a backlog in state enforcement because of budget cuts could drag the reclassification process out years longer than scheduled

  • Scientist: change behavior to give mitigation technologies time to emerge

    One of the world’s foremost authorities on environmental says that there are only three options when it comes to climate change; mitigation, adaptation, and suffering; currently there are no technological quick fixes for global warming, so “Our best hope is to change our behavior in ways that significantly slow the rate of global warming, thereby giving engineers and scientists time to devise, develop, and deploy technological solutions where possible”

  • New kind of blast-resistant glass -- thinner and tougher -- developed

    Current blast-resistant glass technology — the kind that protects the windows of key federal buildings, the president’s limo, and the Pope-mobile — is thicker than a 300 page novel — so thick it cannot be placed in a regular window frame; DHS-funded research develops thinner, yet tougher, glass; the secret to the design’s success is long glass fibers in the form of a woven cloth soaked with liquid plastic and bonded with adhesive

  • WikiLeaks reveals U.S. anxious over infrastructure vulnerability

    Among the leaked documents released by WikiLeaks is a secret list of infrastructure-related facilities and topics, from pipelines to smallpox vaccine suppliers, whose loss or attack by terrorists could “critically impact” U.S. security in the view of the State Department; the February 2009 cable from the State Department requested overseas U.S. missions update a list of infrastructure and resources around the globe “whose loss could critically impact the public health, economic security and/or national and homeland security of the United States”; the list includes undersea cables, communications, ports, mineral resources, and firms of strategic importance in countries ranging from Austria to New Zealand

  • ICx Technologies: comprehensive, layered approach to security

    At the recent ASIS exhibition and seminar, Homeland Security Newswire took the time to walk through the ICx Technologies booth and speak to some of their subject matter experts; CommandSpace® & ThreatSense™, solutions which provide a comprehensive, layered approach to perimeter security and chemical, biological, radiological and nuclear security for critical facilities, respectively, were on display

  • New strategy for UAVs: emulate the soaring approach of peregrine falcons

    UAVs could fly for longer using less power if they copied the counter-intuitive flying patterns of peregrine falcons, say researchers; falcons, instead of spiraling in one direction to stay with a single thermal, constantly change the direction of their spirals

  • Artificial tornadoes created to test Japanese homes

    Japan suffers from many natural disasters, and over the past few years the number of tornados hitting the country has been on the rise; researchers have built a tornado simulator which can generate maximum wind velocity of 15 to 20 meters per second, enough to simulate an F3-size storm; on Japan’s Fujita Scale, an F3 storm is one powerful enough to uproot large trees, lift and hurl cars, knock down walls, and destroy steel-frame structures

  • It's official: asteroids did kill the dinosaurs

    The prevailing scientific consensus is that at least one asteroid — possibly more — hit the earth about sixty-five million years ago, showering the planet with dust and debris, blocking sunlight, causing firestorms, and marking the end of the Cretaceous Period and the beginning of the Paleogene Period; most scientists believe the impact was directly responsible for the mass extinction of many species of plants and animals — most famously, the dinosaurs; geological evidence buried deep in the soil of New Jersey offers support for the impact theory of dinosaur extinction

  • Desalinating water, producing hydrogen, treating wastewater -- simultaneously

    Fresh water and reusable energy: humans are on a constant hunt for a sustainable supply of both; trouble is, water purification requires a lot of energy, while utility companies need large amounts of water for energy production; researchers from the University of Colorado Denver College of Engineering and Applied Science may have discovered an answer

  • Fusion power nears

    The long-sought goal of a practical fusion-power reactor has inched closer to reality with new experiments from MIT’s experimental Alcator C-Mod reactor, the highest-performance university-based fusion device in the world; MIT advance helps remove contaminants that slow fusion reactions

  • Container heist unrelated to Port of Los Angeles

    Investigators in Los Angeles described the heist of three containers as “terminal robbery” — but the heist had nothing to do with the Port of Los Angeles / Long Beach; the facility where the robbery occurred is located miles inland from the port, is not part of a federally regulated port area, and is not governed by the Maritime Transportation Security Act (MTSA) protocol; since stricter port regulations came into effect following the 9/11 attacks, zero containers have been stolen from the Port of Los Angeles
