• Border security advocates criticize wilderness area restrictions

    A proposal to consolidate a swath of 250,000 acres of wilderness study areas in New Mexico has sparked an outcry from groups fearing an influx of illegal immigrants and drugs from Mexico; the Border Patrol says the designation has little effect on its work

  • Closing of U.K. forensics research centers triggers protest

    The U.K. government announced that the Forensic Science Service — a leading research center based in Birmingham, United Kingdom — will be closed by 2012 because of budgetary reasons; law enforcement leaders and scientists calls on the government to reconsider the decision, saying that “The reputation of forensic science in the U.K. will undoubtedly diminish —- The lack of research means that we will be lagging behind the rest of the world, and justice will suffer”

  • China will cut rare earths export quotas yet again

    China produces 97 percent of the world’s rare earth elements; over the last three years it has been steadily reducing the exports of these metals; the Chinese say the reason is the need for growing domestic demand; critics say that China’s goal is to undermine the high-tech sectors of Western countries’ economies; earlier this year China stopped shipping rare earths to Japan following a dispute between the two countries over a couple of small Pacific islands

  • China, U.K. pursue major rail projects; U.S. does not

    Unlike almost every other developed nation, the United States has no national transportation strategy; the nation fails to raise taxes that are supposed to pay for roads and rails. Gasoline taxes, for example, cover only about 50 percent of road projects, much lower than in the past, according to recent Federal Highway Administration figures; once the U.S. recognizes that it needs diversified and integrated air, rail and road transportation, it could well end up importing the technologies, products and expertise it has failed to develop

  • U.S. rare Earth mine resumes active mining

    Colorado-based Molycorp resumed active mining of the rare Earth metal facility at Mountain Pass, California last week; the site had been shutdown in 2002 amid environmental concerns and the low costs for rare Earth metals provided by mining operations based in China

  • New camera technology may give soldiers eyes in the back of their heads

    DARPA is looking for ideas on how to develop a small and light device which will give the user zoom vision, various forms of night sight, and act as a heads-up display besides; perhaps best of all, the proposed kit would also offer “full sphere awareness” — that is, eyes in the back of your head

  • U.S. water contains large amounts of the carcinogen hexavalent chromium

    Drinking water in thirty-five American cities contains the carcinogen hexavalent chromium; in twenty-five of those cities, the levels exceeded the goal proposed in California, which has been trying aggressively to reduce the chemical in its water supply, a probable carcinogen; the chemical compound was first made famous in the hit 2000 Hollywood movie “Erin Brockovich”

  • The best place for a wind turbine: 30,000 feet above ground

    At altitude of 2,000 feet (610 meters), wind velocity is two to three times greater than at ground level; since power production goes up with the cube of that wind velocity, this means that at 2,000 feet above ground, wind produces 8 to 27 times the power produced by wind at ground level; if we send turbines farther aloft, into the 150 mph (240 kph) jet stream at 30,000 feet (9,150 meters), than power production grows from 500 watts per meter for ground-based wind turbines to about 20,000, 40,000 watts per square meter; this is very high energy density — and NASA is examining the project’s feasibility

  • Laws of traditional physics would foil Santa's effort to carry out mission

    Santa has 31 hours to visit 378 million Christian children; at the rate of 3.5 children per household, and assuming at least one good child per home, this comes to 108 million homes; if each child receives no more than a medium sized Lego set (two pounds), the sleigh would be carrying more than 500 thousand tons, not counting Santa himself; Santa would thus need at least 360,000 Reindeer to pull the sleigh; since Santa must visit 108 million homes in 31 hours, he will have to travel at 650 miles per second — 3,000 times the speed of sound; at that speed, the lead pair of Reindeer would absorb 14.3 quintillion joules of energy per second each and vaporize – indeed, the entire Reindeer team would be vaporized within 4.26 thousandths of a second; Santa himself would be subjected to forces of 17,500 Gs; a 250 pound Santa (which seems ludicrously slim) would be pinned to the back of the sleigh by 4,315,015 pounds of force, and be crushed

  • String theory explains Santa Claus

    Calculations maintain that the laws of physics should prevent Santa Claus from delivering all his gifts and that Santa would burn up in the atmosphere if he tried; the Norwegian Internet magazine, forskning.no, has put together a team of four top researchers to look into the case; the panel’s conclusion is clear: Santa can do the job and Christmas is saved!

  • LEMV surveillance airship taking shape

    The persistent-surveillance long-endurance multi-intelligence vehicle (LEMV) is designed to have an endurance when operating unmanned for 21 days at 20,000 ft. carrying a 2,500-lb. payload of sensors and communications equipment; the critical design review was completed at the end of November, final assembly is to begin in February, and first flight is planned for the end of July 2011

  • Giving crowds a lift with spiral escalator

    A monorail-inspired design could help create the world’s first continuous spiral escalator; the spiral escalator could transport larger numbers of people than a lift in a vertical space too narrow for a traditional escalator; this could reduce the floor space needed in buildings for personal transporters and cut the cost of putting escalators into underground railway stations

  • China's dominance in rare Earth elements to weaken

    China currently has a lock on the rare Earth elements market: in 2009 it provided 95 percent of the world’s supply, or 120,000 tons; other countries used to produce rare Earth elements, but environmental and economic considerations led to the near death of the industry outside of China; the growing unease with China’s dominance — and its willingness to exploit this dominance for political gain — have led to a renewed interest in reopening abandoned mines; U.S. company Molycorp has just secured the permits and funding to restart production at a mine in Mountain Pass, California, which would become the first U.S. source of rare Earth elements in more than a decade; full operations will start by the end of next year; by 2012, the revamped U.S. mine is expected to produce around 20,000 tons of rare Earth materials per year

  • Clinical psychology on how American Muslims cope with 9/11 aftermath

    A Tel Aviv University clinical psychologist examines how various Islamic beliefs and practices impact the psychological well-being of its adherents; among American Muslims, he is attempting scientifically to quantify how the after-effects of the 9/11 attacks — after-effects which included many stressors, such as increasing number of security checks, harassment, and verbal abuse — have affected mental well-being and what therapeutic role Islam plays, hoping to identify a clinical path for recovery; it is the first study of its kind and has findings applicable to other religions

  • Biting winters driven by global warming: scientists

    A string of freezing European winters scattered over the last decade has been driven in large part by global warming; the culprit, according to a new study, is the Arctic’s receding surface ice, which at current rates of decline could to disappear entirely during summer months by century’s end; the mechanism uncovered triples the chances that future winters in Europe and north Asia will be similarly inclement, the study reports
