Researchers Succeed in Quantum Teleportation of Light Waves
|12:23:53 AM, Thursday, April 21, 2011|
"In a real-life use of Schrödinger's theoretical paradoxical cat, researchers report that they were able to quickly transfer a complex set of quantum information while preserving its integrity. The information, in the form of light, was manipulated in such a way that it existed in two states at the same time, and it was destroyed in one spot and recreated in another. The new breakthrough is a major step toward building safe, effective quantum computers.
No felines were harmed in the making of this experiment, which actually studied wave packets of light that existed in a state of quantum superposition, meaning they existed in two different phases simultaneously. This phenomenon is described in Erwin Schrodinger’s quantum mechanics thought experiment, in which a cat is simultaneously dead and alive, depending on the state of a subatomic particle.
In this experiment, researchers in Australia and Japan were able to transfer quantum information from one place to another without having to physically move it. It was destroyed in one place and instantly resurrected in another, “alive” again and unchanged. This is a major advance, as previous teleportation experiments were either very slow or caused some information to be lost.
The team employed a mind-boggling set of quantum manipulation techniques to achieve this, including squeezing, photon subtraction, entanglement and homodyne detection. The photo above depicts their device, nicknamed the Teleporter, in the lab of Akira Furusawa at the University of Tokyo.
The results pave the way for high-speed, high-fidelity transmission of information, according to Elanor Huntington, a professor at the University of New South Wales in Australia who was part of the study.
“If we can do this, we can do just about any form of communication needed for any quantum technology,” she said in a news release.
Instead of using ones and zeroes, quantum computers store data as qubits, which can represent one and zero simultaneously. This superposition enables the computers to solve multiple problems at once. The new, faster teleportation process means scientists can move blocks of this quantum information around within a computer or across a network, Huntington said..."

Pluto's Expanding Atmosphere Confounds Researchers
|7:46:17 PM, Wednesday, April 20, 2011|
"Recent observations of Pluto reveal that the icy orb’s atmosphere has expanded dramatically since 2000, and for the first time researchers have detected carbon monoxide. The findings may be evidence of seasonal changes in climate linked to Pluto’s most recent close approach to the sun, but scientists still aren’t sure about how those variations unfold over the course of each 248-year orbit.
Pluto is the only object orbiting in the frigid realm beyond Neptune that is known to have an atmosphere. That tenuous sheath of gas was discovered in 1988 when the “dwarf planet” passed between Earth and a distant star, blocking some of the star’s light. Although telescopic observations at various wavelengths since the early 1990s have since identified several substances in Pluto’s surface ices—including nitrogen, methane, and carbon monoxide—only methane had been detected previously in its atmosphere.
Now scientists can add carbon monoxide to the mix. New observations of the atmosphere’s emissions at various wavelengths, particularly at the 1.3-millimeter wavelength, betray the presence of the gas for the first time. Because carbon monoxide probably could have been observed by instruments in previous studies, its newfound presence likely marks a new stage in the season-by-season evolution of Pluto’s atmosphere, the researchers suggest. Pluto was discovered only about 80 years ago—less than one-third of the time it takes to make a single orbit, notes team member Jane Greaves, an astrobiologist at the University of St. Andrews in the United Kingdom, so “we’re seeing everything happen for the first time.”
Although methane and carbon monoxide are the only gases yet detected in Pluto’s atmosphere, scientists expect that by far the largest constituent is nitrogen, a gas that’s hard to detect due to its subdued emissions characteristics at many wavelengths, Greaves says. “It’s frustrating that we don’t know about 97% of Pluto’s atmosphere.”
The new observations also reveal that Pluto’s atmosphere is growing. Data collected around the turn of the century suggested that Pluto’s cold, diffuse atmosphere extended no more than 135 kilometers above the planet’s surface, Greaves says. But she sees hints of an atmospheric expansion in data that she and her colleagues gathered using telescopes atop Hawaii’s Mauna Kea on 11 nights scattered between August 2009 and May 2010. She says that the atmosphere now reaches heights of more than 3000 kilometers—a distance almost one-quarter of the way to Charon, Pluto’s largest moon. “This is not what we expected,” Greaves says. “The atmosphere has changed so dramatically...""

Solar on the Water
|6:25:35 PM, Wednesday, April 20, 2011|
"Already, 144 solar panels sit atop pontoons moored on a three-acre irrigation pond surrounded by vineyards in Petaluma in Sonoma County. Some 35 miles to the north, in the heart of the Napa Valley, another array of 994 solar panels covers the surface of a pond at the Far Niente Winery.
“Vineyard land in this part of the Napa Valley runs somewhere between $200,000 and $300,000 an acre,” said Larry Maguire, Far Niente’s chief executive. “We wanted to go solar but we didn’t want to pull out vines.”
The company that installed the two arrays, SPG Solar of Novato, Calif., as well as Sunengy of Australia and Solaris Synergy of Israel, are among the companies trying to develop a market for solar panels on agricultural and mining ponds, hydroelectric reservoirs and canals. While it is a niche market, it is potentially a large one globally. The solar panel aqua farms have drawn interest from municipal water agencies, farmers and mining companies enticed by the prospect of finding a new use for — and new revenue from — their liquid assets, solar executives said.
Sunengy, for example, is courting markets in developing countries that are plagued by electricity shortages but have abundant water resources and intense sunshine, according to Philip Connor, the company’s co-founder and chief technology officer..."
Live Human Heart Grown in Lab Using Stem Cells in Potential Transplant Breakthrough
|4:12:52 PM, Wednesday, April 20, 2011|
"Scientists are growing human hearts in laboratories, offering hope for millions of cardiac patients.
American researchers believe the artificial organs could start beating within weeks.
The experiment is a major step towards the first ‘grow-your-own’ heart, and could pave the way for livers, lungs or kidneys to be made to order.
The organs were created by removing muscle cells from donor organs to leave behind tough hearts of connective tissue.
Researchers then injected stem cells which multiplied and grew around the structure, eventually turning into healthy heart cells.
Dr Doris Taylor, an expert in regenerative medicine at the University of Minnesota in Minneapolis, said: ‘The hearts are growing, and we hope they will show signs of beating within the next weeks.
‘There are many hurdles to overcome to generate a fully functioning heart, but my prediction is that it may one day be possible to grow entire organs for transplant.’Patients given normal heart transplants must take drugs to suppress their immune systems for the rest of their lives..."

Cannibals Seeking Same: A Visit To The Online World Of Flesh-Eaters
|7:23:05 PM, Tuesday, April 19, 2011|
"While it was shut down with a Denial of Service attack by the German authorities in late 2002, the website for the Cannibal Café can still be viewed online thanks to the Wayback Machine. Nine years is an eternity when it comes to the Internet and, suspended there in history, the website is a time capsule of early website-design features and flourishes, down to a .gif of dripping blood and the flashing "WARNING" sign. Its forum messages also carry the whiff of a different era; written at a time when people, unaware and unafraid of consequences, were more open with their identities online.
On the Café's forums were men looking for men, men looking for women (the ideal: short, buxom, thin redheads) and women looking for men—very few posts, if any, were for women looking for women. There were people who wanted to be eaten and people who wanted to do the eating. There were stories, artwork and users seeking advice on the best to way to cook someone. “I am ready!” announced that the poster was prepared for slaughter. Entire threads were devoted to “human meat for sale fresh frozen.” Email addresses were freely exchanged, with posters using handles like “Pigslut” and “Masochist Mr. Waye.”
Here is how one notable, but still typical, conversation at the Café ran. The creatively titled “your next meal” wrote, “if anyone wants to eat an 18 yr old gorgeous male by any means you wish, then just tell me how you would feel whilst devouring my horny flesh into ur belly and i will reply to you so we can discuss real arrangements, please eat me!” A few hours later, a response: “Hi, i am Franky from Germany, i will eat you,” followed by an e-mail address.
Perro Loco started the Cannibal Café in 1994—and when, in 2002, one of its posters, that same "Franky from Germany," was arrested for killing and eating another man, the Cannibal Café was shut down.
"Perro Loco" is a pseudonym, of course, one Loco uses for all of his online activity. I spoke to him over the phone last week from his home in California. He described himself as an "average looking guy" who is "well spoken and fairly well educated." Now semi-retired, he worked for many years as an EMT before going to work at a fly-fishing store. On the phone, he speaks slowly and with confidence. Given his history I expected some measure of paranoia, but found little. Although he tries to keep a private lifestyle, anyone wishing to know him will face no difficulties, which is why it wasn’t hard for me to contact him..."
Internet Freedom Threatened By New Restrictions
|6:56:37 PM, Tuesday, April 19, 2011|
"Freedom on the worldwide Internet is in danger, according to a new report by Freedom House.
In a survey of 37 countries, only 8 qualified as having completely "Free" Internets, while 11 were designated "Not Free" and the remainder were "Partly Free." The survey measured Internet freedom by studying obstacles to access, such as governmental efforts to block technologies or control over Internet access providers, limits on content, including the blocking of websites and other forms of censorship, as well as violations of user rights including privacy, online surveillance and real world repercussions for online activity. The U.S. scored second on the list as ranked by most to least free, with Estonia taking the lead as the nation where the Internet was most free. Germany, Australia and the UK were ranked just behind the U.S.
Among the most alarming findings of the report was evidence that a growing number of countries are attempting to restrict the flow on information online by blocking political content and threatening website owners and bloggers with arrest. Even more democratic countries, like the UK, are chipping away at web freedom with other forms of censorship and surveillance, or with legal harassment. The report listed Russia, Venezuela, Zimbabwe, Thailand and Jordan as the countries where a relatively free Internet now threatens to become severely restricted: signs include the 2011 sentencing of a Thai web developer to 13 years of prison over certain web comments, Russian use of "sock puppets" to influence public opinion, and other forms of increased censorship, coercion and restriction..."

First Evidence That Some Dinosaurs Were Nocturnal
|6:43:14 PM, Tuesday, April 19, 2011|
"Many dinosaurs and pterosaurs were active both by day and night, and some were entirely nocturnal, a new study suggests.
Lars Schmitz and Ryosuke Motani at the University of California, Davis, wanted to test the assumption that dinosaurs were mainly active by day.
They hit upon a clever way to reconstruct the activity patterns of extinct archosaurs – a group which includes crocodiles, dinosaurs and birds – by comparing the size and shape of their eyes to those of present-day animals.
The soft tissues of the eye, including the iris, rarely fossilise, but most archosaurs have a ring of bones within the eye called the scleral ring, which is preserved in some fossils. In modern archosaurs, the size and shape of this ring relative to the eye socket varies depending on whether the animal is diurnal, nocturnal or is active mainly at dawn and dusk..."
