If your child won't sit still at the dentist, the doctor, or the kitchen table, you need the PediSedate Helmet. The device consisting of a colorful headset that connects to a game component or a portable CD player. After a snorkel attachment goes into the child's mouth, the helmet will monitor respiratory function and distribute nitrous oxide or anesthetic gas. The company website states, "The child comfortably becomes sedated while playing with a Nintendo Game Boy system or listening to music. This dramatically improves the hospital or dental experience for the child, parents and healthcare providers."

KentuckyFC writes "Cosmologists have been scratching their heads over the discovery of a pattern imprinted on the cosmic microwave background, the radiation left over from the Big Bang. This pattern, the so-called Axis of Evil, just shouldn't be there. Now an independent researcher from Canada says the pattern may be caused by the boundary between the Solar System and interstellar space where there is a sharp change in pressure, temperature and density of ions in space. Known as the termination shock, astronomers had thought this boundary was spherical. But last year, data from the Voyager spacecraft which have crossed the boundary, showed it was asymmetric. The new thinking is that the termination shock acts like a giant lens, refracting light that passes through it. Any distortion of the lens ought to show up as a kind of imprinted pattern on an otherwise random image. But the real eye-opener is that as the shape of the termination shock changes (as the Solar Wind varies, for example), so too should the pattern in the microwave background. And there is tentative evidence that this is happening too (abstract)."

An anonymous reader writes "After the astronauts on the International Space Station finished up their communications with Space Shuttle Atlantis yesterday, the crew on the Space Station did something that no other astronaut has ever done before — drank recycled urine and sweat. The previous shuttle crew that recently returned to Earth brought back samples of the recycled water to make sure it was safe to drink, and all tests came back fine. So on Wednesday, the crew took their recycled urine and said 'cheers' together and toasted the researches and scientists that made the Urine Recycler possible. After drinking the water, they said the taste was great! They also said the water came with labels on it that said 'drink this when real water is over 200 miles away.'"

Hugh Pickens writes "The Telegraph reports on the revolutionary 'STAIR' (St Andrews Air) battery could now pave the way for a new generation of electric cars, laptops and mobile phones. The cells are charged in a traditional way but as power is used an open mesh section of battery draws in oxygen from the surrounding air that reacts with a porous carbon component inside the battery, which creates more energy and helps to continually 'charge' the cell as it is being discharged. The battery has a greater storage capacity than other similar-sized cells and can emit power up to 10 times longer. 'The key is to use oxygen in the air as a re-agent, rather than carry the necessary chemicals around inside the battery,' says Professor Peter Bruce of the Chemistry Department at the University of St Andrews. 'Our target is to get a five to ten fold increase in storage capacity, which is beyond the horizon of current lithium batteries.'"

coondoggie writes "When it comes to satellites sometimes less is more. In the next ten years the government expects to see fewer but ever larger satellites flung into space. Specifically, the folks who monitor such things, the Commercial Space Transportation Advisory Committee (COMSTAC), said in a draft report today that an average 20.8 satellites could be launched from 2009 through 2018, a decrease of one satellite when compared to the 2008 forecast of 21.8 and the 2007 forecast of 21.0 satellites per year. Actual launches per year were above 20 for the first time since 2002 and the highest total since 2000, with 23 satellites launched in 2008. As for the weight, the group said there has been steady growth in satellite mass since 1993 and the trend will continues as satellite mass is expected to remain near or slightly above 100,000 kilograms (220,400 lbs) forecast for the coming years with an all-time high of nearly 116,500 kg (257,000lbs) in 2009, the COMSTAC report stated."

gabrlknght writes "An old element just learned a new trick under pressure. When cooled and squeezed very hard, the soft metallic element europium turns into a superconductor, allowing electrons to flow unfettered by resistance, a study appearing May 13 in Physical Review Letters shows. The results make europium the 53rd of the 92 naturally occurring elements to possess superconductivity, which, if harnessed, could make for more efficient energy transfer."

wjousts writes "As I'm sure many Slashdot readers live almost exclusively on cola drinks, a new warning from doctors: 'Doctors have issued a warning about excessive cola consumption after noticing an increase in the number of patients suffering from muscle problems, according to the June issue of IJCP, the International Journal of Clinical Practice. ... 'Evidence is increasing to suggest that excessive cola consumption can also lead to hypokalaemia, in which the blood potassium levels fall, causing an adverse effect on vital muscle functions.' And sorry, diet colas aren't any better."

langelgjm sends in an update to a story we discussed over the weekend about an extremely well-preserved fossil of an ancient primate, Darwinius masillae, that sheds light on an important area of evolution. The 47 million-year-old specimen has now been officially unveiled, and while many media outlets are stumbling over themselves with phrases like "missing link" and "holy grail," it's clearly a very impressive find. "Discovered two years ago, the exquisitely preserved specimen is not a direct ancestor of monkeys and humans, but hints at what such an ancestor might have looked like. According to researchers, 'The specimen has an unusual history: it was privately collected and sold in two parts, with only the lesser part previously known. The second part, which has just come to light, shows the skeleton to be the most complete primate known in the fossil record.' The scientific article describing the find was published yesterday in the peer-reviewed, open-access journal PLoS ONE. Google's home page is also celebrating the find with a unique image." Science blogger Brian Switek offers some criticism of the academic paper and the media swarm, saying, "I would have hoped that this fossil would receive the care and attention it deserves, but for now it looks like a cash cow for the History Channel. Indeed, this association may not have only presented overblown claims to the public, but hindered good science, as well."

Hugh Pickens writes "The National Geospatial-Intelligence Agency, part of the Department of Defense, is using satellites to track the activities of drug cartels operating along the US-Mexican border. The agency is supplying photos to pinpoint Mexican narcotics operations and anticipate smuggling attempts into the United States. During a conference on border security held in Phoenix last week, Scott Zikmanis said his agency already has supplied some data to the El Paso Intelligence Center, a federal clearinghouse for investigating drug cartels. Any border-security surveillance will be done over Mexico, not the US says Zikmanis because a federal law, the Posse Comitatus Act, strictly limits US military operations on American soil unless such operations are authorized by Congress. Civil rights attorneys question the use of satellite technology in law enforcement. 'We are in the midst of a really dangerous time in terms of technology,' said Chris Calabrese, an attorney with the American Civil Liberties Union. 'The idea that such a powerful tool might be turned on US citizens is really troubling.'"

Al writes "Researchers at the University of Pennsylvania have immunized monkeys against the simian immunodeficiency virus, the animal model that is closest to HIV. They did so by shuttling a gene into the monkeys' muscles, making the muscle cells produce antibody-like molecules that work against SIV. With both SIV and HIV, the chameleon-like mutability of the virus's surface changes so quickly that most antibodies made by the immune system are soon rendered ineffective. Philip Johnson and colleagues designed DNA sequences for two antibodies known to be effective against SIV. They used antibody-like molecules, called immunoadhesins, in which the functional part of an antibody is fused with a more stable section of another antibody. The same approach could be used to deliver antibodies that are effective against HIV, but which the body doesn't normally produce."
