thebestsophist writes “A couple months ago, Scientists and Engineers for America, Science Debate 2008, and a bunch of other science organizations sent McCain, Obama, and all the Congressional candidates a bunch of questions on science and technology. Topics included biosecurity, genetics research, and national security, as well as the more common questions on research and education. Well, Senator Obama just answered.” Senator McCain has not responded to the questionnaire at this point in time, but the site has a profile of his views and actions relating to science policy, which provides a good basis for comparing the candidates’ stances. We’ve previously discussed the differences between the two candidates’ technology platforms. According to a current NPR story, both candidates intend to keep politics out of science.

Pickens writes “City officials ordered everyone to leave New Orleans beginning Sunday morning — the first mandatory evacuation since Hurricane Katrina flooded the city three years ago — as Hurricane Gustav grew into what the city’s mayor called ‘the storm of the century’ and moved toward the Louisiana coast. ‘This is the real deal. This isn’t a test. For everyone thinking they can ride this storm out, I’ve news for you: that’ll be one of the biggest mistakes you can make in your life,’ stated New Orleans mayor, C. Ray Nagin. Already, hundreds of thousands of residents had begun streaming north from New Orleans and other Gulf Coast areas stretching from the Florida Panhandle to Houston. Bush administration officials took pains not to be caught as flatfooted as they were in Hurricane Katrina, announcing that President Bush had called governors in the region to assure them of assistance and that top federal emergency officials were in the region to guide the response. ‘We could see flooding that is worse than what we saw with Katrina,’ stated Louisiana Governor Jindal.” The US Geological Survey will be running a real-time “Map of Hydrologic Impacts” to monitor flood levels, and the National Weather Service has charted direction and wind-speed probabilities. Reader technix4beos points out the need for IRC transcription of FEMA and NOAA feeds.

fahrbot-bot tips a story of mad cow disease, a private meat packer that wants to test all of its beef for the disease, and the USDA, which controls access to the test kits and just won an appeals court ruling that the government has the authority to block testing above and beyond the 1% the agency performs. Creekstone Farms Premium Beef sought to test 100% of its beef, in order to reassure its export markets, especially Japan and South Korea, that its beef is safe. Large meat packers opposed any such private testing, because they feared they would be forced into 100% testing and would have to raise prices. The appeals court ruled, 2 to 1, that under a 1913 law, test kits that are used only after an animal is killed still constitute “diagnosis” and “treatment” — this for a disease that has no treatment and is 100% fatal — and therefore fall under the USDA’s authority to regulate.

rjwoodhead writes “This past weekend, my entire family learned what it’s like to float in freefall aboard G-Force One (recently featured on the Mythbusters’ Moon Hoax show). Being science-lovers, we wanted to do some kind of original experiment. So we decided to test whether the Diet Coke & Mentos reaction was affected by the lack of bubble convection in microgravity. At the link you can find the story of how the experiment evolved and how we talked Space Adventures into letting us fool around with sticky and corrosive cola and candy inside their nice clean airplane, as well as high-speed video of the results.”

Anti-Globalism suggests an article at Science News on the passing of Henri Cartan, one of the founding members of a strange and influential group of French mathematicians in the twentieth century. “In the 1930s, a group of young French mathematicians led an uprising that revolutionized mathematics. France had lost most of a generation in the First World War, so the emerging hotshots in mathematics had few elders to look up to. And when these radicals did look up, they didn’t like what they saw. The practice of mathematics at the time was dry, scattered and muddled, they believed, in need of reinvention and invigoration… Using the nom de plume Nicolas Bourbaki (after a dead Napoleonic general), they wrote a series of textbooks laying out mathematics the right way. Though the young mathematicians started out only intending to write a good textbook for analysis…, they ended up creating dozens of volumes which formed a manifesto for a new philosophy of mathematics. The last of the founders of Bourbaki, Henri Cartan, died August 13 at age 104… Two of his students won the Fields medal…, one won the Nobel Prize in physics and another won the economics Nobel.”

Toren Altair mentions that the Rocket Racing League has video and photos available from their current flight tests of new Armadillo Aerospace liquid oxygen-alcohol engines. “Founded in 2005 by two-time Indianapolis 500 winning team partner Granger Whitelaw and X PRIZE Chairman and CEO Peter H. Diamandis, MD, the Rocket Racing League (RRL) is a new entertainment sports league that combines the exhilaration of racing with the power of rocket engines. To be held at venues across the country, the Rocket Racing League will feature multiple races pitting up to 10 Rocket Racers going head to head in a 4-lap, multiple elimination heat format on a 5-mile ‘Formula One’-like shut circuit raceway in the sky.”

KentuckyFC writes “We’ve long thought that nuclear decay rates are constant regardless of ambient conditions (except in a few special cases where beta decay can be influenced by powerful electric fields). So that makes it hard to explain two puzzling experiments from the 1980s that found periodic variations over many years in the decay rates of silicon-32 and radium-226. Now a new analysis of the raw data says that changes in the decay rate are synchronized with each other and with Earth’s distance from the sun. The physicists behind this work offer two theories to explain why this might be happening (abstract). First, some theorists think the sun produces a field that changes the value of the fine structure constant on Earth as its distance from the sun varies. That would certainly affect the rate of nuclear decay. Another idea is that the effect is caused by some kind of interaction with the neutrino flux from the sun’s interior which also varies with distance. Take your pick. What makes the whole story even more intriguing is that for years physicists have disagreed over the decay rates of several isotopes such as titanium-44, silicon-32, and cesium-137. Perhaps they took their data at different times of the year?”

mattnyc99 writes “There was plenty of chatter last week about an MIT announcement that researcher Angela Belcher had developed a way to create virus-based nanoscale batteries to power mini gadgets of the future. In a fascinating followup at Popular Mechanics, Belcher now says that her unpublished work includes full-scale models of the batteries themselves, and that they could power everything from cars and laptops to medical devices and wearable armor. Quoting: ‘We haven’t ruled out vehicles. That’s a lot of amplification. But right now the thing is trying to make the ideal material possible, and if we get a really great material, then we’ve to consider how do you scale it.’”

n2hightech writes “Harvard University scientists figured out how to activate a trio of dormant genes that commanded non-insulin producing pancreas cells to switch to the Beta type insulin producing cells. The method uses an engineered virus to infect the cells and deliver special proteins that activate the dormant genes. This technology has the potential to make all stem cell based methods obsolete because it does not pose the danger of rejection and cancer associated with stem cells. A simple injection into the area where cells need to be reprogrammed is all that is required.” Gospodin adds a link to coverage at the Washington Post.

An anonymous reader writes with this snippet from Wired: “After six Nobel Prizes, the invention of the transistor, laser and countless contributions to personal science and technology, it is the end of the road for Bell Labs’ fundamental physics research lab. Alcatel-Lucent, the parent company of Bell Labs, is pulling out of basic science, material physics and semiconductor research and will instead be focusing on more immediately marketable areas such as networking, high-speed electronics, wireless, nanotechnology and software.” Jamie points out this list of Bell Labs’ achievements at Wikipedia, including tiny things like the UNIX operating system.
