Jabccba - Yahoo! Mail. Higgs Boson Confirmed | God Particle Found. A newfound particle discovered at the world's largest atom smasher last year is, indeed, a Higgs boson, the particle thought to explain how other particles get their mass, scientists reported today (March 14) at the annual Rencontres de Moriond conference in Italy. Physicists announced on July 4, 2012, that, with more than 99 percent certainty, they had found a new elementary particle weighing about 126 times the mass of the proton that was likely the long-sought Higgs boson. The Higgs is sometimes referred to as the "God particle," to the chagrin of many scientists, who prefer its official name.
But the two experiments, CMS and ATLAS, hadn't collected enough data to say the particle was, for sure, the Higgs boson, the last undiscovered piece of the puzzle predicted by the Standard Model, the reigning theory of particle physics. Seeing how this particle decays into other particles could let physicists know whether this Higgs is the "plain vanilla" Standard Model Higgs. Topic Index. Spooky! Quantum Action Is 10,000 Times Faster Than Light. How fast do quantum interactions happen? Faster than light, 10,000 times faster. That's what a team of physicists led by Juan Yin at the University of Science and Technology of China in Shanghai found in an experiment involving entangled photons, or photons that remain intimately connected, even when separated by vast distances.They wanted to see what would happen if you tried assigning a speed to what Einstein called "spooky action at a distance.
" They didn't find anything unexpected, but that wasn't the point: in physics, sometimes it's good to be sure. The group published their work on the ArXiv.org, a preprint server for physics papers. All tangled up Quantum physicists have long known that after two particles — photons, for example — interact, they sometimes become "entangled. " When photon A is observed, it has a certain polarization, perhaps "up. " As Chad Orzel, assistant professor of physics at Union College, explained, "It's as though you sent two cards to two different addresses. First Interstellar Spacecraft May Use Texas-Size Solar Sail. The first-ever interstellar probe may cruise through space like a boat through the ocean, propelled by super-focused light beamed onto a sail the size of Texas. Solar sailing is perhaps humanity's best bet for reaching star systems beyond our own in the foreseeable future, some scientists say, though they caution that the first robotic interstellar flight is not exactly around the corner.
"I think it's 300 to 500 years [away], personally," said Les Johnson, deputy manager of the Advanced Concepts Office at NASA's Marshall Space Flight Center in Huntsville, Ala. "I think before we ever really undertake sending something to another star, we will probably have to be masters of our own solar system. " The vastness of space Humanity will need to employ new propulsion technology if it hopes to launch spacecraft to other stars, because the distances involved are just too huge for traditional chemical rockets to handle. A light breeze Beaming energy from afar Aim high. Mini Black Holes Easier To Make Than Thought.
Creating microscopic black holes using particle accelerators requires less energy than previously thought, researchers say. If physicists do succeed in creating black holes with such energies on Earth, the achievement could prove the existence of extra dimensions in the universe, physicists noted. Any such black holes would pose no risk to Earth, however, scientists added. Black holes possess gravitational fields so powerful that nothing can escape, not even light.
The holes normally form when the remains of a dead star collapse under their own gravity, squeezing their mass together. A number of theories about the universe suggest the existence of extra dimensions of reality, each folded up into sizes ranging from as tiny as a proton to as big as a fraction of a millimeter. When the most powerful particle accelerator in the world, the Large Hadron Collider, was coming online, scientists wondered if it might become a "black hole factory," generating a black hole as often as every second. Gravity Satellite Felt Japan Quake from Space. A European Space Agency satellite circling Earth was able to detect the massive 2011 earthquake that ravaged Japan, killing nearly 16,000 people and causing massive destruction, a new study said. "The atmospheric infrasounds following the great Tohoku earthquake ... induced variations of air density and vertical acceleration of the GOCE platform," said a report published in the journal Geophysical Research Letters.
PHOTOS: Japan Earthquake and Tsunami: Before and After The Gravity Ocean Circulation Explorer (GOCE) is the European Space Agency super-sensitive satellite that acts like an orbital seismologist. Scientists argue that earthquakes not only create seismic waves that travel through Earth's interior, but large tremors also cause the surface of the planet to vibrate like a drum. GOCE is designed to capture and register these signals.
According to the report, the magnitude 9.0 tremor on March 11, 2011 sent shock waves through the atmosphere that was picked up by the satellite. AgustaWestland unveils world's first electric tilt rotor aircraft. Project Zero is claimed to be the world's first electric tilt rotor aircraft Image Gallery (4 images) The engineers at aerospace firm AgustaWestland are no slouches when it comes to tilt rotor aircraft, having recently developed the intriguing commercial-use AW609. It seems, however, that they’ve been holding out on us ... over a year and a half ago, they began secretly test-flying what they have now publicly unveiled as being the world’s first electric tilt rotor airplane. It’s known simply as Project Zero. The technology demonstrator aircraft was reportedly designed and built over a period of just six months.
As with other tilt rotor aircraft, Project Zero’s two rotors can be tilted up to 90 degrees. Project Zero’s control systems, flight controls and landing gear actuators are also all electrically powered, which means no hydraulic system is required – the plane also doesn’t require a transmission.

The modular, build-it-yourself Teal camper is officially available for purchase. Teal debuted its first model, the Tail Feather, at the Colorado RV, Sports, Boat and Travel Show last week and has begun production on the camper, which features a few structural changes from when we last saw it. View all The original idea behind the Teal camper was to make owning and using a camper more versatile and convenient. To reach this goal, Teal implemented a build-it-yourself, multi-panel design. Instead of taking up a big portion of the garage or driveway throughout the year, the Teal camper can be disassembled and stored neatly – the panels even nest together to minimize the space they take up.
Teal's campers can be left empty and used to haul gear (e.g. dirt bikes or work equipment) or outfitted for mobile living. When we covered the Teal Camper last May, designer Lawrence Drake was still searching for a manufacturing partner to turn his design into a marketable reality. Source: Teal Camper. Improved ion engines will open up the outer Solar System. The phrase "engage the ion drive" still has the ring of a line from Star Wars, but these engines have been used in space missions for more than four decades and remain the subject of ongoing research. Ion engines have incredible fuel efficiency, but their low thrust requires very long operating times ... and therein lies the rub.
To date, erosion within such an engine seriously limits its operational lifetime. Now a group of researchers at NASA's Jet Propulsion Laboratory (JPL) has developed a new design that largely eliminates this erosion, opening the gates for higher thrust and more efficient drives for manned and unmanned missions to the reaches of the Solar System. Ion engines of various types have been used on space missions since at least 1964, when NASA flew the suborbital Space Electric Rocket Test I mission. Many classes of space missions can benefit through using fuel efficient ion engines during some phase of their mission. How does an ion engine work? Design roadblock. Monster Mosquitoes Poised to Strike Florida | Gallinipper Psorophora Ciliata. One of the most ferocious insects you've ever heard of — it's the size of a quarter and its painful bite has been compared to being knifed — is set to invade Florida this summer.
The Sunshine State, already home to man-eating sinkholes, invading Burmese pythons, swarming sharks, tropical storms and other disasters, can expect to see an explosion of shaggy-haired gallinippers (Psorophora ciliata), a type of giant mosquito, according to entomologist Phil Kaufman of the University of Florida. Gallinipper eggs hatch after a rainstorm or flood, and the state saw a big jump in the numbers of gallinippers last summer after Tropical Storm Debby dumped its load on Florida.
Eggs laid last year could produce a bumper crop of the blood-sucking bugs this summer if Florida sees a soggy rainy season. "I wouldn't be surprised, given the numbers we saw last year," Kaufman said in a statement. "When we hit the rainy cycle, we may see that again. " As insects go, gallinippers are particularly formidable. Planet Mercury Fully Mapped for First Time | Messenger Spacecraft.
The surface of the planet Mercury has been completely mapped for the first time in history, scientists say. The closest planet to the sun hasn't received as much scientific attention as some of its more flashy solar system neighbors, such as Mars, but NASA's Messenger spacecraft is helping to close the gap. The probe has been in orbit around Mercury since March 2011, and its team announced Feb. 28 that the spacecraft had finished mapping the planet's surface. "We can now say we have imaged every square meter of Mercury's surface from orbit," said Messenger principal investigator Sean Solomon of Columbia University's Lamont-Doherty Earth Observatory.
"Admittedly, some regions are in permanent shadow, but we're actually peering into those shadows with our imaging systems. " Before Messenger, less than half the surface had been imaged by NASA's Mariner 10 spacecraft, which made several flybys of Mercury in 1974 and 1975.

Scientists shined a little light, literally, on the perplexing processes that govern atoms, in a new experiment that showed the effect of bouncing one photon of light off an atom.
Atoms and particles obey a set of rules called quantum mechanics that are quite different from the rules of ordinary objects. "The main difference between quantum mechanical behavior and classical behavior is that quantum systems can exist in several states, several realities at the same time," explained Roee Ozeri, a physicist at the Weizmann Institute of Science in Israel. "They can be in several positions at the same time, or can point in several directions at the same time. " For everyday objects in the macroscopic world, though, this ability to be in two places at once, called superposition, is lost, and classical physics takes over. When a quantum system transitions into the classical world, it's called decoherence. [Stunning Photos of the Very Small] The new study may just be a step in that direction.
Sicherheitstacho.eu. Yahoo! School textbook defines ‘hippies’ as followers of rock stars who may have worshipped Satan | The Sideshow. Hippies (AmericaBlog) A school participating in Louisiana Gov. Bobby Jindal's controversial voucher program is apparently using a history book that teaches its eighth-grade students that "hippies" were dirty followers of Satan-worshipping rock musicians.
The textbook, “America: Land I Love," includes a section on the counterculture movement of the 1960s. Here's a paragraph taken from that section, which was published Wednesday by AmericaBlog.com: (AmericaBlog) Many young people turned to drugs and immoral lifestyles; these youth became known as hippies. They went without bathing, wore dirty, ragged, unconventional clothing, and deliberately broke all codes of politeness or manners. It's not clear which school is using the aforementioned textbook. But this isn't the first time books used in Jindal's voucher program—which allows poor and middle-class students the opportunity to attend private schools that often have religion-based curricula—have been called into question.
And: New Type of Bacteria Reportedly Found in Buried Antarctic Lake. A new type of microbe has been found at a lake buried under Antarctica's thick ice, according to news reports. The find may unveil clues of the surrounding environment in the lake, according to scientists. The bacteria, said to be only 86 percent similar to other types known to exist on Earth, was discovered in a water sample taken from Lake Vostok, which sits under more than 2 miles (3 kilometers) of Antarctic ice.
The freshwater lake has likely been buried, unaltered, under the ice for the past million years. Russian scientists reportedly obtained the water samples in 2012 when they drilled all the way down to the lake's surface. They ran the bacteria's composition through a global database and were not able to find anything similar to its type. Scientists couldn't even figure out the bacteria's descendents. "We are calling this life form unclassified and unidentified," he added.
Understanding the environment 'If this is real, it is very exciting' Some insect wings found to have natural antibiotics | The Lookout. Cicada (Photo courtesy of iStockphoto) Cicadas can’t exactly carry around Purell to keep their wings clean. But scientists have discovered that the locustlike insects have something even better: wings that naturally kill some bacteria on contact. The clanger cicada turns out to be something of a clean freak. The journal Nature reports that it keeps some bacteria away through the structure of its bumpy wings: teeny tiny spikes that kill bacteria by ripping them apart.
Here’s how it works: The insect’s wings are covered by a hexagonal layer of nanopillars—the spikes. According to Nature, this is one of the first natural surfaces to have such a power—a power that could be used for even more good. Scientists are suggesting that the findings could be potentially used to keep public surfaces clean, like handrails. Science, Social Science, & HumanitiesBiology. On Jupiter's Moon Europa, Underground Ocean Bubbles Up to Surface. The huge ocean sloshing beneath the icy shell of Jupiter's moon Europa likely makes its way to the surface in some places, suggesting astronomers may not need to drill down deep to investigate it, a new study reports.
Scientists have detected chemicals on Europa's frozen surface that could only come from the global liquid-water ocean beneath, implying the two are in contact and potentially opening a window into an environment that may be capable of supporting life as we know it. "We now have evidence that Europa's ocean is not isolated — that the ocean and the surface talk to each other and exchange chemicals," study lead author Mike Brown, of Caltech in Pasadena, said in a statement. "That means that energy might be going into the ocean, which is important in terms of the possibilities for life there," Brown added. "It also means that if you’d like to know what’s in the ocean, you can just go to the surface and scrape some off.
