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."

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."

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."

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."

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."

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."

feldhaus writes "The BBC reports that the first beams for over one year have been successfully sent around the complete circumference of the Large Hadron Collider. Engineers do not yet have a stable circulating beam but they hope to by 0600 GMT on Saturday."

huckamania was one of many readers to write with the news that the University of East Anglia's Hadley Climatic Research Unit was hacked, and internal documents released. Some discussion and analysis of the leaked items can be found at Watts Up With That. The CRU has confirmed that a breach occurred, but not that all 61 MB of released material is genuine. Some of the emails would seem to raise concerns about the science as practiced — or at least beg an explanation. From the Watts Up link: "[The CRU] is widely recognized as one of the world's leading institutions concerned with the study of natural and anthropogenic climate change. Consisting of a staff of around thirty research scientists and students, the Unit has developed a number of the data sets widely used in climate research, including the global temperature record used to monitor the state of the climate system, as well as statistical software packages and climate models. An unknown person put postings on some climate skeptic websites that advertised an FTP file on a Russian FTP server. Here is the message that was placed on the Air Vent today: 'We feel that climate science is, in the current situation, too important to be kept under wraps. We hereby release a random selection of correspondence, code, and documents.' The file was large, about 61 megabytes, containing hundreds of files. It contained data, code, and emails apparently from the CRU. If proved legitimate, these bombshells could spell trouble for the AGW crowd." Reader brandaman supplied the link to the archive of pilfered data. Reader aretae characterized the emails as revealing "...lots of intrigue, data manipulation, attempting to shut out opposing points of view out of scientific journals. Almost makes you think it's a religion. Anyone surprised?" And reader bugnuts adds, for context: "These emails are certainly taken out of context, whether they are legitimate or fraudulent, which adds to the confusion."

eldavojohn writes "Both the EU and US are using a strategy to merge what used to be two separate searches: the search for exoplanets that may harbor life and the search for dark energy. In an effort to develop 'robust, low-risk missions that maximize the scientific return,' the article analyzes how, without any changes, a space-based dark energy telescope could also check for microlensing events indicating an exoplanet."

Lucas123 writes "Scientists at Intel are working on developing sensors that would be implanted in a person's head in order to harness brain waves that could then be used to control computers, televisions, cell phones and other electronic equipment. Intel has already used Functional Magnetic Resonance Imaging (FMRI) machines to determine that blood flow changes in specific areas of the brain based on what word or image someone is thinking of. People tend to show the same brain patterns for similar thoughts. 'Eventually people may be willing to be more committed ... to brain implants. Imagine being able to surf the Web with the power of your thoughts.' said Intel research scientist Dean Pomerleau."

An anonymous reader writes "The Nuclear Regulatory Commission has taken pity on it's loverlorn engineers and is now offering to help find dates for them. From the article: 'Jim McDermott, chief human capital officer of the Nuclear Regulatory Commission, thinks he's found a foolproof way to convince young engineers to come to his agency: Find them dates. "There are incentives, and then there are incentives," McDermott told a crowd of human resources officials at the HCMF Conference in Arlington, Va., earlier today. "When we’re hiring, we say, 'Is there a significant other in the picture'; If there’s no significant other, I tell them, 'We can help.''"

Hugh Pickens writes "The Telegraph reports that 4,000 microscopic worms were onboard Space Shuttle Atlantis when it launched today. Their mission: to help experts in human physiology understand more about what triggers the body to build and lose muscle. The worms are bound for the Japanese Experiment Module 'Kibo' on the International Space Station, where they will experience the same weightless conditions which can cause dramatic muscle loss, one of the major health concerns for astronauts. 'If we can identify what causes the body to react in certain ways in space we establish new pathways for research back on earth,' says Dr. Nathaniel Szewczyk."

mmmscience writes "CT scans of mummies have revealed that heart disease was also a common problem 3500 years ago. The scans show calcification of arterial pathways, a preserved sign of atherosclerosis, the heart disease caused by hardening arteries. Of the 16 mummies that had intact arteries, nine showed signs of significant calcification. Dr. Gregory Thomas, co-lead author on the study, stated, 'The findings suggest that we may have to look beyond modern risk factors to fully understand the disease.'"

coondoggie writes "Some math problems are as old as the wind, experts say, and many remain truly unsolved. But a new open source-based site from the American Institute of Mathematics looks to help track work done and solve long-standing and difficult math problems. The Institute, along with the National Science Foundation, has opened the AIM Problem Lists site to offer an organized and annotated collection of unsolved problems, and previously unsolved problems, in a specialized area of mathematics research. The problem list provides a snapshot of the current state of research in a particular research area, letting experts track new developments, and newcomers gain a perspective on the subject."

mbstone writes "Aside from ending painful daily fingerpricking for millions, the invention of the color-changing blood sugar tattoo should also reduce the vast amount spent on glucose test strips ($1/test). Next, I want to see artistic diabetic tattoos that morph according to the wearer's blood sugar."

wiedzmin writes "DeCODE Genetics, a genetics research firm from Iceland, has filed for bankruptcy in the US, and Saga Investments, a US venture capital firm, has already put in a bid to buy deCODE’s operations, raising privacy concerns about the fate of customer DNA samples and records. The company hasn’t disclosed how many clients signed up for its service, but provides a number of customer testimonials on its site, including Dorrit Mousaieff, Iceland’s first lady."
