The HF Active Auroral Research Program (HAARP) (a Google Video) radio signals are clearly heard in the 40 meter band, echoing off the Moon. This video shows S-meter readings as seen on a Yaesu FT-1000MP amateur radio (ham radio) transceiver located in San Jose, California. And of course a thorough explanation of what you are watching/hearing can be found on About the HAARP - LWA Moon Bounce Experiment.
So apparently it's not the lack of oxygen which causes cells to die. Rather, getting oxygen back, which triggers the same cell death mechanism that guards against cancer, causes cell death.
Hey, bisexuals! Is your sweetheart terrified that you’ll have second thoughts after graduation? Are you trying to figure out how to tell your parents? Are presidential primary frontrunners lumping your orientation together with pedophilia and bestiality? Well, for the first two, at least, you can reassure them that bisexuality is not a phase ... by quoting SCIENCE! (pdf) (Side effects may include cheering at increasing cultural acceptance or eye-rolling at need to continue to demonstrate the obvious. Effects have been demonstrated in women only. Presidential primary frontrunners may be immune to science.)

In 1798, English economist Thomas Malthus promised "Famine ... the last, the most dreadful resource of nature." It took another 125 years for world population to double, but only 50 more for it to redouble. By the 1940s, Mexico, China, India, Russia, and Europe were hungry.
64-year-old Frank Pringle has figured out a way to extract oil and natural gas out of nearly anything.
Dr. President: "The next president of the United States of America will control a $150 billion annual research budget, 200,000 scientists, and 38 major research institutions and all their related labs. This president will shape human endeavors in space, bioethics debates, and the energy landscape of the 21st century." With the coming election, the AAAS has created a new website and devoted a section of their journal Science to the Democratic and Republican candidates' positions on science and technology issues. But to help further clarify their positions, some people are calling for the candidates to have a presidential debate on science and technology. [Via The Intersection and Wired Science.]
The scholarly literature forms a vast network of academic papers connected to one another by citations in bibliographies and footnotes. The structure of this network reflects millions of decisions by individual scholars about which papers are important and relevant to their own work. Therefore within the structure of this network is a wealth of information about the relative influence of individual journals, and also about the patterns of relations among academic disciplines. Our aim at eigenfactor.org is develop ways of extracting this information. [more inside]
"So by this analysis dead-tree magazines have a smaller net carbon footprint than web media. We cut down trees and put them in the ground. From a climate change perspective, this is a good thing" explains Chris Anderson, Wired Magazine's editor-in-chief. While some decry this type of carbon footprint accounting as "cheating", the paper industry has lately been eager to convince the public that they are carbon-neutral.

Parmenides. "The pre-Socratic philosopher sparked an intellectual revolution that still echoes today. Yet for philosophy and science to continue to progress in the 21st century, we may need to embark on an entirely new cognitive journey ."
The dangers of living in a zero-sum world economy - naked capitalism reprints (with added commentary) an FT article by Martin Wolf on why it's vital for (civilised) society to sustain a 'positive-sum' world, otherwise: "A zero-sum economy leads, inevitably, to repression at home and plunder abroad." Wolf's solution? "The condition for success is successful investment in human ingenuity." Of course! Some are calling for more socialism, while others would press on to build more megaprojects. For me, at least part of the solution lies in environmental accounting and natural capitalism :P

Darwin's Surprise. "There may be no biological process more complicated than the relationships that viruses have with their hosts. Could it be that their persistence made it possible for humans to thrive?" [Via Disinformation.]
Astronomers find a giant hole a billion light years across & located 8 billion light years away from us. They believe it could be evidence of another Universe at the edge of ours.
Could giant magnetically levitated windmills be the solution to the worlds energy problems? Chinese scientist have reported 20 percent increase in capacity over traditional wind turbines using maglev turbines, and now Arizona-based based Maglev Wind Turbine Technologies claims their turbines will have 1000 times the capacity of a traditional turbine. Not everybody is convinced.
What Makes Us Moral and The Morality Quiz. It's war time, and you're hiding in a basement with a group of other people. Enemy soldiers are approaching outside and will be drawn to any sound. If you're found, you'll all be killed immediately. A baby hiding with you starts to cry loudly and cannot be stopped. Smothering it to death is the only way to silence it, saving the lives of everyone in the room. Assume that the parents of the baby are unknown and not present and there will be no penalty for killing the child. Could you be the one who smothered it if no one else would?

Scientists discover fossilized claw of enormous ancient sea scorpion. They estimate this thing was 2.5 meters long. Sorry about the nightmares. [via]
After recent promising results demonstrating the ability to change mouse skin cells into stem cells, researchers have replicated this change in human skin cells in papers published in Science and Cell (access to full articles requires subscription) . The White House, somehow, is trying to take credit for this. The potential of all this: huge.

The Inner Life of an Intelligently Designed Cell? Remember The Inner Life of a Cell animation (discussed here)? Apparently the Discovery Institute (recently discussed here) is showing it in presentations with a new title and narration, and without attribution.
Theory of Humor. A scientific paper, written by Tom Veatch, describes his Theory of Humor. When is something funny? When is it not funny? When does it cross the line? Why are puns generally shitty? And the mysterious and magical powers elephant jokes have on children, revealed! A great data set to use for practice in applying the theories presented in the paper can be found here.
Remember that X-files episode? The one with the robot cockroaches from outer space? Well, scientists in Belgium have created robots that act like cockroaches, and are accepted by the real cockroaches because they smell sexy to them. Better yet, the scientists were able to use the robots to change how the cockroaches behaved. [more inside]

The forest preserve of Białowieza is considered to be the last primeval forest in lowland Europe. Because of its unique position on the border of the temperate and boreal climate zones, it contains a unique mixture of trees, such as Norway Spruce and oaks. It also contains an interesting mix of fauna, including the European Bison, beaver, wolves, and the Nazi re-creation of an extinct species. [more inside]
NASA proposes using a Stirling cooler (essentially a Stirling engine in reverse) to keep a probe cool on the surface of Venus, which has had a tendency to melt or smash previous probes. The cooler would maintain a 25cm sphere within the probe at 200°C -- 100°C above the boiling point of water but sufficiently cool for a high-temperature microcontroller to operate. The waste heat radiators on the exterior of the sphere would reach the temperature of 500°C, 40°C above the the normal Venusian surface temperature.
Jonah Lehrer is becoming one of the most interesting science writers around. The 26-year-old Rhodes scholar and former Le Bernardin cook just published his first book, Proust Was a Neuroscientist [first chapter excerpt - NYT], an investigation of the ways poets, novelists, and artists accurately modeled the brain and memory before science did. This week he hilariously reenacted Escoffier's distillation of umami-rich veal stock [hit the audio link] with NPR's Robert Krulwich of Radio Lab. He also just published a very insightful profile of Oliver Sacks in SEED (addressing the pioneering neurologist's own recent struggles with an eye ailment) and writes a wide-ranging science blog. A new writer to watch.
Sex Ratio Theory, Ancient and Modern - An 18th Century Debate about Intelligent Design and the Development of Models in Evolutionary Biology [pdf file]. The design argument for the existence of God took a probabilistic turn in the 17th and 18th centuries. Earlier versions, such as Thomas Aquinas’ 5th way, usually embraced the premise that goal-directed systems (things that “act for an end” or have a function) must have been created by an intelligent designer. This idea – which we might express by the slogan “no design without a designer” – survived into the 17th and 18th centuries, and it is with us still in the writings of many creationists. The new version of the argument, inspired by the emerging mathematical theory of probability, removed the premise of necessity. It begins with the thought that goal-directed systems might have arisen by intelligent design or by chance; the problem is to discern which hypothesis is more plausible. From Professor Elliott Sober.
Have You Eaten Your Dirt Today, Honey? A New Approach To The Hygiene Hypothesis. The hypothesis argues: The reason why there is so much asthma, eczema, allergies and maybe even childhood diabetes in the modern world is because we — well infants really — live in too clean a universe. What our baby immune systems need is a kickstart by exposure to viruses, bacteria, worms, pollutants and so on. If you don’t get an infant hit from these icons of uncleanliness, the immune system goes haywire and your body over-reacts to all sorts of invasive things that normally could be ignored. Via.

Yummy Science. Researchers unravel the complex combination of physical and emotional reactions that influence our perceptions of what tastes good. Once upon a time, flavor research was a matter of asking housewives to munch a few potato chips... Now it's about providing an exceptional flavor "experience." And as scientists learn to exploit the ways we perceive flavor, food manufacturers will be able to refine their products to appeal to us as individuals. Welcome to the world of personally tailored mass-produced food.
British diplomat William Hamilton (whose 2nd wife Emma is perhaps best known for having a scandalous public affair with Horatio Nelson) loved volcanoes. His 1776 book Campi Flegrei: Observations on the volcanoes of the two Sicilies* used stunning hand-coloured illustrations by Peter Fabris to demonstrate to the scientific world that volcanic processes can be beautifully creative as well as horribly destructive.
