For Jane's, Gustav Weißkopf's 1901 Liftoff Displaces Wright Bros. 267

Posted by timothy from the ahem-there's-been-a-development dept.
gentryx writes "Newly found evidence supports earlier claims that Gustave Whitehead (a German immigrant, born Gustav Weißkopf, with Whitehead being the literal translation of Weißkopf) performed the first powered, controlled, heavier-than-air flight as early as 1901-08-14 — more than two years before the Wrights took off. A reconstructed image shows him mid-flight. A detailed analysis of said photo can be found here. Apparently the results are convincing enough that even Jane's chimes in. His plane is also better looking than the Wright Flyer I." (And when it comes to displacing the Wright brothers, don't forget Alberto Santos Dumont.)

The Science of Hugo Chavez's Long Term Embalming 215

Posted by Unknown Lamer from the beyond-the-grave dept.
Hugh Pickens writes writes "Discover Magazine reports that Hugo Chavez will apparently get an embalming job designed to keep him looking alive for decades similar to that of Russia's Vladimir Lenin, whose body still lies in a mausoleum in Moscow's Red Square, nearly 90 years after his death. So how do you preserve a human body for decades without it turning into a pile of melted tissue? First, get to work quickly. Upon death, the human body starts decomposing immediately. The way to stop it is with formaldehyde, a preservative used for the past century, which inhibits the enzyme decomposition as well as killing bacteria. 'You pump the chemical in, and as the formaldehyde hits the cells of the body, it firms up the protein of the cell, or fixates it,' says Vernie Fountain, head of the Fountain National Academy of Professional Embalming Skills in Springfield, Mo. 'That's what makes them stiff.' With a body that will have to be on display for years, it's likely to require a top-shelf, super-strong solution. 'If I were doing Hugo Chavez, I would strengthen the solution and use more preservative product,' says Fountain. Next, get a good moisturizer. Formaldehyde preserves, but it also dries out the body. Vaseline or other moisturizers can preserve the look of skin, according to Melissa Johnson Williams, executive director of the American Society of Embalmers. Finally keep cool. Heat decomposes a body so for long term preservation, the body has to be kept at the temperature of a standard kitchen refrigerator, somewhere in the mid-40s. Lastly, if Venezuelans really want to keep Hugo Chavez around forever, like many other world figures, there's only one solution that works, according to Fountain. 'The best form of preservation is mummification.'"

Physicists Discover 13 New Solutions To Three-Body Problem 127

Posted by Unknown Lamer from the mystical-spheres dept.
sciencehabit writes "It's the sort of abstract puzzle that keeps a scientist awake at night: Can you predict how three objects will orbit each other in a repeating pattern? In the 300 years since this 'three-body problem' was first recognized, just three families of solutions have been found. Now, two physicists have discovered 13 new families. It's quite a feat in mathematical physics, and it could conceivably help astrophysicists understand new planetary systems." The paper is available at arxiv.

The Manti Te'o of Physics 101

Posted by Unknown Lamer from the international-man-of-intrigue-by-night dept.
theodp writes "When it comes to tales of fake girlfriends, Manti Te'o can't hold a candle to theoretical particle physicist Paul Frampton. In November 2011, writes the NY Times' Maxine Swann in 'The Professor, the Bikini Model and the Suitcase Full of Trouble,' Frampton met who he says he thought was Czech bikini model Denise Milani on Mate1.com. A Yahoo Messenger romance bloomed, at least in the 68-year-old Frampton's mind (Frampton's ex-wife was a self-described 'physics groupie'). But before starting their perfect life together, fake Denise asked Frampton for one little favor — would he be so kind as to bring her a bag that she had left in La Paz, Bolivia? Yep, bad idea. The UNC Louis D. Rubin, Jr. Distinguished Professor of Physics and Astronomy soon found himself in a Buenos Aries prison, charged with transporting two kilos of cocaine into Argentina. Currently serving a four years and eight months sentence under house arrest, Frampton reportedly continues to supervise his two current PhD students by phone, and still finds time to post to the Physics archive."

If Video Games Make People Violent, So Do Pictures of Snakes 161

Posted by timothy from the what-about-drones dept.
New submitter phenopticon writes with this nugget from an intriguing piece at Gamasutra that adds another voice to the slow-burn debate on the psychological effects of video games: "For nearly thirty years we've been having this discussion, asking the question: do violent movies, music or video games make people violent? Well according to Brad Bushman and Craig Anderson of Iowa State University, yes. Based on the results of their research they concluded in 2001 that video games and violent media can make people aggressive and violent. Based upon their data and their conclusions, however, it's safe to say that photos of snakes, crispy bacon, or a particularly rigorous game of chess can also make people aggressive and violent."

US CompSci Enrollment Leaps For 5th Straight Year 176

Posted by timothy from the they-heard-about-the-snacks-and-dancing dept.
dcblogs writes "The number of new undergraduate computing majors in U.S. computer science departments increased more than 29% last year, a pace called 'astonishing' by the Computing Research Association. The increase was the fifth straight annual computer science enrollment gain, according to the CRA's annual survey of computer science departments at Ph.D.-granting institutions. The survey also found that more students are earning a Ph.D., with 1,929 degrees granted — an 8.2% increase over the prior year. The pool of undergraduate students represented in the CRA survey is 67,850. Of that number, 57,500 are in computer science."

NSF Audit Finds Numerous Cases of Alleged Plagiarism 44

Posted by Soulskill from the because-there-are-no-consequences-to-scamming-the-government dept.
sciencehabit writes "The National Science Foundation (NSF) is investigating nearly 100 cases of suspected plagiarism drawn from a single year's worth of proposals funded by the agency. The cases grow out of an internal examination by NSF's Office of Inspector General (IG) of every proposal that NSF funded in fiscal year 2011. James Kroll, head of administrative investigations within the IG's office, tells ScienceInsider that applying plagiarism software to NSF's entire portfolio of some 8000 awards made that year resulted in a 'hit rate' of 1% to 1.5%. 'My group is now swamped,' he says about his staff of six investigators."

Man Has 75% of Skull Replaced By 3D-Printed Materials 74

Posted by Soulskill from the i-wonder-if-they'll-do-customized-designs dept.
redletterdave writes "An un-named male patient in the U.S. has had 75 percent of his skull replaced with 3D printed materials. The undisclosed patient had his head imaged by a 3D scanner before South Windsor, Conn.-based Oxford Performance Materials (OPM) gained approval from US regulators to print the bone replacement. OPM's final skull replacement was built within two weeks, and inserted in the patient's skull in an operation performed earlier this week; this cutting-edge procedure was only just revealed on Friday. OPM's 3D-printed process was granted approval by the FDA back on Feb. 18, which means the company can now provide 3D printed replacements for bones damaged by trauma or even disease. The company says this technique could benefit more than 500 U.S. citizens each month, from injured factory or construction workers to wounded soldiers."

Caffeine Improves Memory In Bees 41

Posted by Soulskill from the able-to-find-their-bee-dentures-reliably dept.
sciencehabit writes "After a long day buzzing between flowers, even the most industrious worker bee could use a little help remembering which ones she wants to return to the next day. Some plants have a trick to ensure they end up at the top of the list: caffeinated nectar. A team of researchers bombarded honey bees with floral smells paired with sugary rewards, some of which contained the same levels of caffeine found in the nectar of coffee and citrus flowers. Three times as many bees remembered the odors associated with caffeine after 24 hours, when compared with the scents associated with sugar alone (abstract). When the researchers applied the stimulant directly to honey bee brains, it had a positive effect on the neurons associated with the formation of long term memories. Now, they want to see if bees go out of their way to feed on caffeinated nectar, perhaps even ignoring predators to do so—behavior that, if observed, could shed light on the neurological processes behind addiction."

Scientists Have Re-Cloned Mice To the 25th Generation 134

Posted by Soulskill from the time-to-locate-jango-fett dept.
derekmead writes "Dolly's mere existence was profound. It was also unusually short, at just six years. But scientists in Japan announced yesterday they have succeeded in cloning mice using the same technique that created Dolly with more or less perfect results: The mice are healthy, they live just as long as regular mice, and they've been flawlessly cloned and recloned from the same source to the 25th generation. Researchers claim it's the first example of seamless, repeat cloning using the Dolly method—known as "somatic cell nuclear transfer" (SCNT)—in which the nucleus from an adult source animal is transferred to an egg with its nucleus removed. Until recently, the process was fraught with failures and mutations. But the team led by Teruhiko Wakayama, whose results were published today in the journal Cell Stem Cell, was able to create 581 clones from the same original mouse. Scientists, including Dolly's creator, have long felt the process was still too unstable—and too wasteful of precious eggs, given the failure rate—to be used on humans any time soon. But perhaps it's not so far off, after all."

Global Temperatures Are Close To 11,000-Year Peak 416

Posted by Soulskill from the but-it-was-cold-yesterday dept.
ananyo writes "Global average temperatures are now higher than they have been for about 75% of the past 11,300 years, a study published in Science suggests. Researchers have reconstructed global climate trends all the way back to when the Northern Hemisphere was emerging from the most recent ice age. They looked at 73 overlapping temperature records including sediment cores drilled from lake bottoms and sea floors around the world, and ice cores collected in Antarctica and Greenland. For some records, the researchers inferred past temperatures from the ratio of magnesium and calcium ions in the shells of microscopic creatures that had died and dropped to the ocean floor; for others, they measured the lengths of long-chain organic molecules called alkenones that were trapped in the sediments. From the first decade of the twentieth century to now, global average temperatures rose from near their coldest point since the ice age to nearly their warmest, they report (abstract)."

Most Doctors Don't Think Patients Need Full Access To Med Records 659

Posted by samzenpus from the for-our-eyes-only dept.
Lucas123 writes "While electronic medical records (EMR) may contain your health information, most physicians think you should only be able to add information to them, not get access to all of the contents. A survey released this week of 3,700 physicians in eight countries found that only 31% of them believe patients should have full access to their medical record; 65% believe patients should have only limited access. Four percent said patients should have no access at all. The findings were consistent among doctors surveyed in eight countries: Australia, Canada, England, France, Germany, Singapore, Spain and the United States."

Ancient Flood Channels Cut Deep Into Mars 46

Posted by samzenpus from the high-water-mark dept.
astroengine writes "Relatively recently, water blasted out from an underground aquifer on Mars, carving out deep flood channels in the surface that were later buried by lava flows, radar images complied from NASA's Mars Reconnaissance Orbiter probe shows. The channels are at least twice as deep as previous estimates for Marte Vallis, an expanse of plains just north of the Martian equator that is the youngest volcanic region on the planet. "We see similar channels elsewhere on Mars and they are not filled with lava so it's important to be able to compare different channel systems, and also similar systems on Earth, to give us clues about how they formed," lead researcher Gareth Morgan, with the Smithsonian Institution in Washington DC, told Discovery News."

RocketAcademy writes "The Lone Star State is moving to become a leader in spaceport development. The Houston Airport System is officially moving ahead with plans to turn Ellington Airport, near NASA's Johnson Space Center, into an FAA-licensed commercial spaceport. The airport system has completed a feasibility study for turning the field into a spaceport for suborbital spacecraft such as Virgin Galactic's SpaceShip Two and XCOR's Lynx. In the longer term, spacecraft could link Houston to Singapore in as little as three hours, according to airport system director Mario Diaz. Meanwhile, state Representative Rene Oliveira (D-Brownsville) introduced a bill that would allow county commissioners to close a local beach for launches from the proposed SpaceX launch site in Cameron County. The bill is part of a flood of spaceport-related legislation that has been introduced recently in the Texas legislature."

Clues of Life's Origins Found In Galactic Cloud 80

Posted by samzenpus from the it's-full-of-stars dept.
astroengine writes "Finding things like amino acids in space directly is a difficult business. So, instead of finding them directly, a team using West Virginia's Green Bank Telescope, led by Anthony Remijan, discovered two other molecules – cyanomethanimine and ethanamine — both of which are precursor molecules. In other words, these molecules are the early steps in the chain of chemical reactions that go on to make the stuff of life. The researchers found these molecules near the center of the Milky Way inside a hulking interstellar cloud known as Sagittarius B2 (Sgr B2), spanning 150 light-years in size, up to 40 times as dense as any other cloud the Milky Way has to offer."

Android In Space: STRaND-1 Satellite To Activate Nexus One 103

Posted by timothy from the roaming-charges-will-get-you dept.
An anonymous reader writes "In as little as a few days, the British-made Surrey Training, Research, and Nanosatellite Demonstrator (STRaND-1) satellite will begin transitioning its key systems over to a completely stock Android Nexus One smartphone that's been bolted to the bottom of it. The mission is designed to test the endurance of off-the-shelf consumer hardware, and to validate Android as a viable platform for controlling low-cost spacecraft. STRaND-1 managed to beat NASA's own 'PhoneSat' mission to the punch, which will see a Nexus One and Nexus S launched into space aboard the April test flight of the Orbital Sciences Antares commercial launch vehicle, the prime competitor to SpaceX's Falcon 9."

Using Google To Help Predict Side Effects of Mixing Drugs 47

Posted by samzenpus from the dr.-everyone dept.
sciencehabit writes "Pharmaceuticals often have side effects that go unnoticed until they're already available to the public. Doctors and even the FDA have a hard time predicting what drug combinations will lead to serious problems. But thanks to people scouring the web for the side effects of the drugs they're taking, researchers have now shown that Google and other search engines can be mined for dangerous drug combinations. In a new study, scientists tried the approach out on predicting hypoglycemia, or low blood sugar. They found that the data-mining procedure correctly predicted whether a drug combo did or did not cause hypoglycemia about 81% of the time."

Sunstone Unearthed From Sixteenth Century Shipwreck 114

Posted by samzenpus from the guided-by-the-light dept.
sciencehabit writes "In 1592, a British ship sank near the island of Alderney in the English Channel carrying an odd piece of cargo: a small, angular crystal. Once it was brought back to land, a few European scientists began to suspect the mysterious object might be a calcite crystal, a powerful 'sunstone' referred to in Norse legends which they believe Vikings and other European seafarers used to navigate before the introduction of the magnetic compass. Now, after subjecting the object to a battery of mechanical and chemical tests, the team has determined that the Alderman crystal is indeed a calcite and, therefore, could have been the ship's optical compass. Today, similar calcite crystals are used by astronomers to analyze the atmospheres of exoplanets—perhaps setting the stage for a whole new age of exploration."
