The Center for Biological Diversity wants to help put a polar bear in your pants with their endangered species condom campaign. They hope that giving away 100,000 free Endangered Species Condoms across the country will highlight how unsustainable human population growth is driving species to extinction, and instill the sexual prowess of the coquí guajón rock frog, nature's most passionate lover, in the condom users. From the article: "To help people understand the impact of overpopulation on other species, and to give them a chance to take action in their own lives, the Center is distributing free packets of Endangered Species Condoms depicting six separate species: the polar bear, snail darter, spotted owl, American burying beetle, jaguar, and coquí guajón rock frog."

KentuckyFC writes "In a truly frightening study, physicists at the University of Oxford have identified a massive miscalculation that makes the LHC safety assurances more or less invalid (abstract). The focus of their work is not the safety of particle accelerators per se but the chances of any particular scientific argument being wrong. 'If the probability estimate given by an argument is dwarfed by the chance that the argument itself is flawed, then the estimate is suspect,' say the team. That has serious implications for the LHC, which some people worry could generate black holes that will swallow the planet. Nobody at CERN has put a figure on the chances of the LHC destroying the planet. One study simply said: 'there is no risk of any significance whatsoever from such black holes.' The danger is that this thinking could be entirely flawed, but what are the chances of this? The Oxford team say that roughly one in a thousand scientific papers have to be withdrawn because of errors but generously suppose that in particle physics, the rate is one in 10,000."

RickRussellTX writes "The UN reports that a variety of the rust fungus originally detected in Uganda in 1999 has already spread as far north as Iran, threatening wheat production across its range. The fungus infects wheat stems and affects 80% of wheat varieties, putting crops at risk and threatening the food sources for billions of people across central Asia. Although scientists believe they can develop resistant hybrids, the fungus is moving much faster than anticipated and resistant hybrids may still be years away. Meanwhile, national governments in the path of the fungus are telling folks that there is nothing to worry about."

moon_monkey writes "According to New Scientist, Darpa is soliciting proposals for so-called Chemical Robots (ChemBots) that would be soft, flexible and could manoeuvre through openings smaller than their static structural dimensions. They suggest that it could be made from shape-memory materials, electro- or magneto-rheological materials or even folding components."

quant-guru writes "Man's domination of light continues. New Scientist is running a story that highlights recent theoretical proposals for a photonic insulator, an engineered material that could make photons solidify. From the article: "OK, it wouldn't be a material in the everyday sense of the word, like a solid you could touch, but it could behave like one in some important ways...photons interacting in a quantum material could give us insights into how real materials with quantum properties work." One proposal by Greetree et al. (Nature Physics) (preprint) imagines a device that will allow many photons to interact with each other simultaneously in diamond, with phases reminiscent of real materials (from superfluid to insulating). This could lead to novel devices based on quantum phenomena, for quantum communication or quantum computers as examples. Similar proposals were made concurrently by two other groups: Angelakis et al. and Hartmann et al. (Nature Physics) (preprint). University of Cambridge physicist Charlie Tahan has more information and links (with step-by-step pictures) on his site."

IAmTheDave writes "A California anti-pretexting bill that got unanimous support in the state senate with a vote of 30-0 was struck down after heavy last-minute lobbying by the MPAA. The bill aimed to make deceptive 'pretexting' (lying) to gain personal information on another person illegal. The MPAA told legislators 'We need to pose as someone other than who we are to stop illegal downloading,' and thus killed the bill when it came up for a final vote. California passed a much narrower bill that 'bans the use of deceit to obtain telephone calling records, and nothing else.' In a final 'think of the children' bid, the Califonia Association of Licensed Investigators also opposed the bill, saying it needed to be able to use pretexting to help find missing children, among other things."

Mantrid42 writes "Schools in the UK are getting rid of their WiFi network, citing health concerns from parents and teachers. The wireless emanations, parents fear, may be the root cause of a host of problems from simple fatigue to the possibility of cancer. A few scientists think younger humans may be more vulnerable to the transmissions, because of thinner skulls. From the article: "Vivienne Baron, who is bringing up Sebastian, her ten-year-old grandson, said: 'I did not want Sebastian exposed to a wireless computer network at school. No real evidence has been produced to prove that this new technology is safe in the long term. Until it is, I think we should take a precautionary approach and use cabled systems.'"
