Remembering Sealab 138

An anonymous reader writes "'Some people remember Sealab as being a classified program, but it was trying not to be,' says Ben Hellwarth, author of the new book Sealab: America's Forgotten Quest to Live and Work on the Ocean Floor, which aims to 'bring some long overdue attention to the marine version of the space program.' In the 1960s, the media largely ignored the efforts of America's aquanauts, who revolutionized deep-sea diving and paved the way for the underwater construction work being done today on offshore oil platforms. It didn't help that the public didn't understand the challenges of saturation diving; in a comical exchange a telephone operator initially refuses to connect a call between President Johnson and Aquanaut Scott Carpenter, (who sounded like a cartoon character, thanks to the helium atmosphere in his pressurized living quarters). But in spite of being remembered as a failure, the final incarnation of Sealab did provide cover for a very successful Cold War spy program."

Air Guns Shake Up Earthquake Monitoring 38

sciencehabit writes "Petroleum geologists have long used air guns in their search for oil and gas deposits. Sudden blasts from the devices generate seismic waves that they use to map underground rock formations. Could the same technique be used to study earthquakes? A team of Chinese scientists thinks so. The researchers have designed an air gun that could be useful in monitoring changes in stress buildup along fault zones."

Finding Lost Recording From the 1880s 128

An anonymous reader writes "The NY Times recently ran a story on the discovery of a cache of wax cylinder records, recorded in Europe in the 1880s, of Otto von Bismarck, Helmuth von Moltke, and various musicians. 'In June 1889, Edison sent Wangemann to Europe, initially to ensure that the phonograph at the Paris World’s Fair remained in working order. After Paris, Wangemann toured his native Germany, recording musical artists and often visiting the homes of prominent members of society who were fascinated with the talking machine. Until now, the only available recording from Wangemann’s European trip has been a well-known and well-worn cylinder of Brahms playing an excerpt from his first Hungarian Dance. That recording is so damaged "that many listeners can scarcely discern the sound of a piano, which has in turn tarnished the reputations of both Wangemann and the Edison phonograph of the late 1880s," Dr. Feaster said. "These newly unearthed examples vindicate both."'"

Milky Way Magnetic Fields Charted 14

eldavojohn writes "Using radio telescope data, scientists from around the world have plotted the Milky Way Galaxy's magnetic field in the form of Faraday Depth. From the article, 'For 150 years, scientists have measured cosmic magnetic field by observing the Faraday effect. They know that when polarized light passes though a magnetized medium, the plane of polarization turns. This concept is called Faraday rotation. The strength and direction of the magnetic field governs the amount of rotation that occurs. So scientists observe the rotation to investigate the magnetic fields' properties. Radio astronomers study the polarized light from distant radio source, passing through the Milky Way on the way to Earth, in order to measure our Galaxy's magnetic field. By measuring the polarization of the light sources at different frequencies, researchers can determine the amount of Faraday rotation.' In the future, radio telescope technologies like LOFAR, eVLA, ASKAP, MeerKAT and the SKA hope to provide enhanced Faraday rotation data so scientists can better understand turbulence in galactic gas and these galactic magnetic field structures."

$100,000 Prize: Prove Quantum Computers Impossible 324

mikejuk writes "Quantum computing is currently a major area of research — but is this all a waste of effort? Now Scott Aaronson, a well-known MIT computer scientist, has offered a prize of $100,000 for any proof that quantum computers are impossible: 'I'm now offering a US$100,000 award for a demonstration, convincing to me, that scalable quantum computing is impossible in the physical world.' Notice the two important conditions — 'physical world' and 'scalable.' The proof doesn't have to rule out tiny 'toy' quantum computers, only those that could do any useful work."

The Destruction of Iraq's Once-Great Universities 444

Harperdog writes "Hugh Gusterson has written a devastating article about what has happened to Iraq's once great university system, and puts most of the blame for its total collapse on the U.S. Quoting: 'While American troops guarded the Ministries of Oil and the Interior but ignored cultural heritage sites, looters ransacked the universities. For example, the entire library collections at the University of Baghdad's College of Arts and at the University of Basra were destroyed. The Washington Post's Rajiv Chandresekara described the scene at Mustansiriya University in 2003: "By April 12, the campus of yellow-brick buildings and grassy courtyards was stripped of its books, computers, lab equipment and desks. Even electrical wiring was pulled from the walls. What was not stolen was set ablaze, sending dark smoke billowing over the capital that day."'"

World's Largest Virtual Optical Telescope Created 57

erice writes "Astronomers in Chile linked four telescopes together to form a single virtual mirror 130 meters in diameter. Previous efforts had linked two telescopes but this is the first time that all four had been linked. 'The process that links separate telescopes together is known as interferometry. In this mode, the VLT becomes the biggest ground-based optical telescope on earth. Besides creating a gigantic virtual mirror, interferometry also greatly improves the telescope's spatial resolution and zooming capabilities.'"

Researchers Feel Pressure To Cite Superfluous Papers 107

ananyo writes "One in five academics in a variety of social science and business fields say they have been asked to pad their papers with superfluous references in order to get published. The figures, from a survey published in the journal Science (abstract), also suggest that journal editors strategically target junior faculty, who in turn were more willing to acquiesce. The controversial practice is not new: those studying publication ethics have for many years noted that some editors encourage extra references in order to boost a journal's impact factor (a measure of the average number of citations an article in the journal receives over two years). But the survey is the first to try to quantify what it calls 'coercive citation,' and shows that this is 'uncomfortably common.' Perhaps the most striking finding of the survey was that although 86% of the respondents said that coercion was inappropriate, and 81% thought it damaged a journal's prestige, 57% said they would add superfluous citations to a paper before submitting it to a journal known to coerce. However, figures from Thomson Reuters suggest that social-science journals tend to have more self-citations than basic-science journals."

Doctors 'Cheating' On Board Certifications 238

Maximum Prophet writes "After taking board exams, doctors have been routinely getting together to remember and reproduce as much of the exam as they can. These notes are then bound and reproduced. According to the American Board of Dermatology, the exams are protected by copyright laws, and any reproduction not approved by the board is illegal. While I have no doubt that the Board believes this, and pays lawyers to believe it as well, I don't think they understand copyright. Perhaps they should invest in better testing methods."

83-Year-Old Woman Gets New 3D-Printed Titanium Jaw 121

arnodf writes "The University of Hasselt (in Belgium) announced today (Google translation of Dutch original) that Belgian and Dutch scientists have successfully replaced an 83-year-old woman's lower jaw with a 3D-printed model. According to the researchers, 'It is the first custom-made implant in the world to replace an entire lower jaw. ... The 3D printer prints titanium powder layer by layer, while a computer controlled laser ensures that the correct particles are fused together. Using 3D printing technology, less materials are needed and the production time is much shorter than traditional manufacturing. The artificial jaw is slightly heavier than a natural jaw, but the patient can easily get used to it."

Did North Korea Conduct Secret Nuclear Tests? 159

gbrumfiel writes "In May of 2010, North Korea made the bizarre claim that it had achieved nuclear fusion. Many, many commentators (including faithful Slashdot readers) mocked the dear leader for his outlandish boast, but could there have been a kernel of truth in the claim? Apparently some odd radioactivity was spotted by detectors surrounding the North just days after the announcement. Now, a new analysis by a Swedish scientist suggests that the radiation may have leaked from covert experiments into boosting fission warheads. The evidence is tentative at best, and many are skeptical, but it does seem that something odd was up on the Korean peninsula that spring."

Chinese Boy Claims To Have Cat-Like Night Vision 171

Oswald McWeany writes "Reports swirling around the Internet are that a boy in China may have cat-like night vision. The boy with eerie blue-eyes was able to fill out a questionnaire in the dark and his eyes reflect like a cat's when a light is shined on them. No reports yet if he marks his territory or is litter box trained."

Alzheimer's Transmission Pathway Discovered 154

smitty777 writes "Two separate studies by the Taub Institute and Harvard have discovered the pathway used by Alzheimer's Disease to spread through the brain. The studies indicate it's not a virus, but a distorted protein called Tau which moves from cell to cell. Further, the discovery 'may now offer scientists a way to move forward and develop a way to block tau's spread in Alzheimer's patients, said Karen Duff, a researcher at Columbia's Taub Institute for Research on Alzheimer's disease and co-author of one study published Wednesday in the journal PLoS One. "It's enlightening for us because it now provides a whole other area for potential therapeutic impact," said Duff. "It's possible that you can identify the disease and intervene (with potential tau-blocking drugs) before the dementia actually sets in."'"

Researchers Create Glass Just 3 Atoms Thick 160

sciencehabit writes "Researchers have created the world's thinnest pane of glass. The glass, made of silicon and oxygen, formed accidentally when the scientists were making graphene, an atom-thick sheet of carbon, on copper-covered quartz. They believe an air leak caused the copper to react with the quartz, which is also made of silicon and oxygen, producing a glass layer with the graphene. The glass is a mere three atoms thick — the minimum thickness of silica glass—which makes it two-dimensional. The team notes that the structure 'strikingly resembles' a diagram drawn by a glass theorist attempting to unravel its structure back in 1932. Such ultra-thin glass could be used in semiconductor or graphene transistors." See Nano Letters for an abstract (and another picture) to the paywalled article.

Norway Brings DNA Sequencing To National Healthcare 91

ananyo writes "Norway is set to become the first country to incorporate genome sequencing into its national health-care system. The Scandinavian nation, which has a population of 4.8 million, will use 'next-generation' DNA sequencers to trawl for mutations in tumors that might reveal which cancer treatments would be most effective. In its three-year pilot phase, the Norwegian Cancer Genomics Consortium will sequence the tumor genomes of 1,000 patients in the hope of influencing their treatments. It will also look at another 3,000 previously obtained tumor biopsies to get a better idea of the mutations in different cancers, and how they influence a patient's response to a drug. In a second phase, the project will build the laboratory, clinical and computing infrastructure needed to bring such care to the 25,000 Norwegians who are diagnosed with cancer each year. Similar projects are under way in the United Kingdom and at research hospitals in the United States, France and elsewhere. But Norway's will be among the first to look for tumor mutations using next-generation DNA sequencing rather than conventional genetic testing."

New Exoplanet Is Best Yet Candidate For Supporting Life 288

First time accepted submitter uigrad_2000 writes "With all the new exoplanets discovered recently with Kepler, it seemed a sure thing that the first exoplanet in the habitable zone of a star would be found soon. The irony is that Kepler was not involved. GJ 667Cc is at least 4.5 times as massive as Earth, and lies in the habitable region of its host star, reports Scientific American. It was discovered by comparing public data from the ESO to recent observations from Hawaii and Chile. As opposed to the stars Kepler is watching, this is only 22 light-years away, making it even more interesting."

Next-Gen Spacesuits 123

ambermichelle writes "Outer space is a hostile environment for humans, characterized by an airless vacuum, thermal extremes, ionizing radiation and speeding micro meteoroids. Less well-known are the dangers posed by long-term exposure to microgravity or zero-g conditions, which over time severely saps the strength of astronauts' muscles and bones. Several researchers are working to develop new spacesuit designs that could help counteract these threats as well as avoid some of the familiar drawbacks of current spacesuit models such as bulk, weight and rigidity."

FDA Regulating Your Stem Cells As Interstate Commerce 332

New submitter dcbrianw writes "A non-surgical procedure that treats joint pain involves removing stem cells from a patient's blood and reinserting them into the joint. The facility conducting these procedures resides in Colorado, but because it orders equipment to perform the procedure from outside of Colorado, the FDA claims it must regulate this process and that it can classify stem cells as a drug. This issue opens the debate of what the FDA, or other regulatory bodies, may regulate within each of our own bodies."

Is the Earth Gaining Or Losing Mass? 356

Hugh Pickens writes writes "BBC recently asked physicist and Cambridge University professor Dave Ansell to draw up a balance sheet of the mass that's coming in to the earth, and the mass going out to find out if the earth is gaining or losing mass. By far the biggest contributor to the world's mass is the 40,000 tonnes of dust that is falling from space to Earth every year. 'The Earth is acting like a giant vacuum cleaner powered by gravity in space, pulling in particles of dust,' says Dr. Chris Smith. Another factor increasing the earth's mass is global warming which adds about 160 tonnes a year because as the temperature of the Earth goes up, energy is added to the system, so the mass must go up. On the minus side, at the very center of the Earth, within the inner core, there exists a sphere of uranium five mile in diameter which acts as a natural nuclear reactor so these nuclear reactions cause a loss of mass of about 16 tonnes per year."
