Comments: 73 +-   Program To Detect Smuggled Nuclear Bombs Stalls on Monday November 23, @06:11PM

Pickens writes "The NY Times reports that a program to detect plutonium or uranium in shipping containers has stalled because the United States has run out of helium 3, a crucial raw material needed to build the 1,300 to 1,400 machines to be deployed in ports around the world to thwart terrorists who might try to deliver a nuclear bomb to a big city by stashing it in one of the millions of containers that enter the United States every year. Helium 3 is an unusual form of the element that is formed when tritium, an ingredient of hydrogen bombs, decays — but the government mostly stopped making tritium in 1989 after accumulating a substantial stockpile of Helium 3 as a byproduct of maintaining nuclear weapons. 'I have not heard any explanation of why this was not entirely foreseeable,' says Representative Brad Miller, chairman of a House subcommittee that is investigating the problem. Helium 3 is not hazardous or even chemically reactive, and it is not the only material that can be used for neutron detection. The Homeland Security Department has older equipment that can look for radioactivity, but it does not differentiate well between bomb fuel and innocuous materials that naturally emit radiation like cat litter, ceramic tiles and bananas — and sounds false alarms more often. In a letter to President Obama, Miller called the shortage 'a national crisis' and said the price had jumped to $2,000 a liter from $100 in the last few years. With continuing concern that Al Qaida or other terrorists will try to smuggle a nuclear weapon into the United States, Congress has mandated that, by 2012, all containers bound for the US be inspected overseas."

Comments: 182 +-   LHC Has First Collisions After Years of Waiting on Monday November 23, @04:43PM

An anonymous reader writes "Only four days after the first attempt to send a particle beam around the LHC, we have arrived at the point when all four experiments got their first real collisions from the machine. This was met by celebrations and champagne, as people have been waiting years and years for this moment. It is a testament to the engineering of the machine that collisions were reached already, so few days after restarting. The LHC had already demonstrated ca 10h stable beams, and now also stable beams in both directions at the same time. In the coming weeks, we need only wait for increased intensity and the first attempts at acceleration."

education
In a speech at the White House today, President Obama launched a new campaign, "Educate to Innovate," designed to get American students fired up about science, technology, engineering, and math (STEM). The full text of the speech is also available on whitehouse.gov. "The new campaign builds on the President's Inaugural Address, which included a vow to put science 'in its rightful place.' One of those rightful places, of course, is the classroom. Yet too often our schools lack support for teachers or the other resources needed to convey the practical utility and remarkable beauty of science and engineering. As a result, students become overwhelmed in their classes and ultimately disengaged. They lose, and our nation loses too. The partnerships launched today aim to change that. They respond to a challenge made by the President in April, when he spoke at the annual meeting of the National Academy of Sciences and asked the nation's philanthropists, professional and educational societies, corporations, and individuals to collaborate and innovate with the goal of reinvigorating America's STEM educational enterprise. The partnerships announced today — dramatic commitments in the hundreds of millions of dollars, generated through novel collaborations and creative outreach activities — are just the first wave of commitments anticipated in response to his call."

Comments: 236 +-   After 35 Years, Another Message Sent From Arecibo on Sunday November 22, @10:11PM

0xdeadbeef writes "Two weeks ago, MIT artist-in-residence Joe Davis used the Arecibo radio telescope to send a message to three stars in honor of the 35th anniversary of the famous Drake-Sagan transmission to M13 in 1974. It was apparently allowed but not endorsed by the director of the facility, and used a jury-rigged signal source on what will now be known as the 'coolest iPhone in the world.' The message encoded a DNA sequence, but no word yet on whether it disabled any alien shields. You can get the low-down on Centauri Dreams: Part 1, Part 2."

Comments: 531 +-   Is That Sushi Hazardous To Your Health? on Sunday November 22, @07:18PM

pdclarry writes "A recent study by scientists at the American Museum of Natural History and Columbia University found that a piece of tuna sushi may not be tuna at all: 'A piece of tuna sushi has the potential to be an endangered species, a fraud or a health hazard,' wrote the authors. 'All three of these cases were uncovered in this study.' The study, published in PLoS ONE examined 68 samples of tuna sushi purchased from 31 restaurants in Manhattan (New York City) and Denver, Colorado. Some of these were from endangered species, others were not as labeled, and some were not tuna at all. Of these last, five samples labeled as 'white tuna' were from a toxic fish, Escolar, which is a gempylid species banned for sale in Italy and Japan due to health concerns. 'It can cause gastrointestinal symptoms ranging from mild and rapid passage of oily yellow or orange droplets, to severe diarrhea with nausea and vomiting. The milder symptoms have been referred to as keriorrhea [i.e. flow of wax in Greek].' Fraud in sushi is not new; Slashdot also reported study on mislabeling in 2008. This new study shows that some sushi can actually make you sick. The study was also covered by Wired."

ElectricSteve writes "Scientists at Cornell University report they can now use a light beam carrying a single milliwatt of power to move objects and even change the optical properties of silicon from opaque to transparent at the nanometric scale." As the article says, such an advancement "could prove very useful for the future of micro-electromechanical (MEMS) and micro-optomechanical (MOMS) systems."

jamie writes with this snippet from the UK's Independent: "The world is now firmly on course for the worst-case scenario in terms of climate change, with average global temperatures rising by up to 6C by the end of the century, leading scientists said yesterday. ... [The study] found that there has been a 29 per cent increase in global CO2 emissions from fossil fuel between 2000 and 2008, the last year for which figures are available. On average, the researchers found, there was an annual increase in emissions of just over 3 per cent during the period, compared with an annual increase of 1 per cent between 1990 and 2000. Almost all of the increase this decade occurred after 2000 and resulted from the boom in the Chinese economy. The researchers predict a small decrease this year due to the recession, but further increases from 2010."

Comments: 136 +-   WHO Says Swine Flu May Have Peaked In the US on Saturday November 21, @11:18AM

Hugh Pickens writes "The World Health Organization says that there were 'early signs of a peak' in swine flu activity in parts of the Northern Hemisphere, including the US. The American College Health Association, which surveys more than 250 colleges with more than three million students, said new flu cases had dropped 27 percent in the week ending on November 13th from the week before, the first drop since school resumed in the fall. Nonetheless, Dr. Anne Schuchat, the director of vaccination and respiratory disease at the CDC, chose her words carefully. 'We are in better shape today than we were a couple of weeks ago,' she says. 'I wish I knew if we had hit the peak. Even if a peak has occurred, half the people who are going to get sick haven't gotten sick yet.' Privately, federal health officials say they fear that if they concede the flu has peaked, Americans will become complacent and lose interest in getting vaccinated, increasing the chances of another wave. However, Dr. Lone Simonsen, a former CDC epidemiologist, says she expects a third wave in December or January, possibly beginning in the South again. Based on death rates in New York City and in Scandinavia, Simonsen argues that both 1918 and 1957 had mild spring waves followed by two stronger waves, one in fall and one in midwinter, adding that in the pandemic of 1889, the bulk of the deaths occurred in the third wave. 'If people think it's going away, they can think again.'"

Mr2001 writes "Consumerist reports that Apple is refusing to work on computers that have been used in smoking households. 'The Apple store called and informed me that due to the computer having been used in a house where there was smoking, [the warranty has been voided] and they refuse to work on the machine "due to health risks of second hand smoke,"' wrote one customer. Another said, 'When I asked for an explanation, she said [the owner of the iMac is] a smoker and it's contaminated with cigarette smoke, which they consider a bio-hazard! I checked my Applecare warranty and it says nothing about not honoring warranties if the owner is a smoker.' Apple claims that honoring the warranty would be an OSHA violation. (Remember when they claimed enabling 802.11n for free would be a Sarbanes-Oxley violation?)"

eldavojohn writes "Almost 6 years ago we discussed a vaccine to help people quit smoking as it entered human clinical trials. Now it looks like the finishing touches have been put on a deal that will go into effect once phase III testing of the drug now called NicVAX is completed. NicVAX was developed by Nabi Biopharmaceuticals, who have agreed to license it to GlaxoSmithKline Biologicals; it is expected to complete phase III testing successfully. Others have fallen short of this goal, in pursuit of a smoking-cessation market expected to hit $4.6 billion worldwide by 2016. Nabi has also sold an experimental vaccine for staph infections; and in 2008 we discussed news of a cocaine vaccine."
