Harperdog writes "Nature just published this study of sea-level rise and how global warming does not force the it to happen everywhere at the same rate. Interesting stuff about what, exactly, contributes to this uneven rise, and how the East Coast of the U.S., which used to have a relatively low sea level, is now a hotspot in that the sea level there is rising faster than elsewhere."

NASA's been solicited ideas for exploring Mars, but Dutch entrepreneur Bas Lansdorp is already planning a different kind of trip than is likely to come from the U.S. government. Lansdorp's Mars One project has the goal of putting humans on Mars in 2022, with a twist that might dampen many people's hopes to be a Mars-exploring astronaut: the trip Lansdorp plans is one-way only. That means dramatically less fuel on board, because unlike typical Mars voyage plans, there would be no need (or ability) to carry the mechanism or the energy storage to return to Earth. If you (and three close companions) are willing to go be the first people to die on Mars, you'll also need to give up more than a pinch of privacy, because the Mars One plan to obtain the necessary funding is straightforward: create a media spectacle, and monetize it through advertising. (Note: If Elon Musk's optimistic sounding predictions are right, maybe one-way Marstronauts can get a return ticket, after all.) Many questions about the proposed journey are answered in the project's FAQ; check there before formulating questions. Ask Lansdorp about the practicalities and impracticalities of reaching Mars with as many questions as you'd like, but (lest ye be modded down) please only one question per post.

theodp writes "The Commercial Appeal reports that Dr. James Eason, the surgeon who performed Steve Jobs' liver transplant, found himself grilled at length Monday by Shelby County Commission members. The Univ. of Tennessee-Methodist Transplant Institute, which Eason heads, is in a bitter dispute over the distribution of human organs. Pressed for details by Commissioners West Bunker and Terry Roland about the 2009 liver transplant that Eason performed on the late Steve Jobs, Eason acknowledged that he's now living in the Memphis home that Jobs used during his convalescence. Bunker asked, "Was that a deal cut to get him a transplant here locally?" Eason: "I understand. It's a fair question. Absolutely not." Eason said a company lined up the housing for Jobs. "I took care of him and visited him in that home. And when I learned that it was going to be going on the market, I asked him, I asked the administrator of the LLC, if I could purchase it." So, is it time for Apple to shed some light on The Mystery of Steve Jobs' Memphis Mansion? It was reported that Apple lawyer George Riley, reportedly a friend of Eason's, helped Jobs with the arrangements for the Memphis mansion, which was acquired at a bargain price of $850,000 from the State of Tennessee by the mysterious LCHG, LLC on 3/26/2009. LCHG was formed on 3/17/2009, apparently just days before Jobs received his liver (on 3/21/2010, Jobs noted he was coming up on the 1-year anniversary of his transplant). Records show that title to the mansion was transferred to Eason in May, 2011, about three months after the National Enquirer painted a grim picture of Jobs' health. LCHG, LLC was dissolved in February 2012."

astroengine writes "Launched in August of last year, NASA's Juno probe is on a Kamikaze mission to go prospecting for water on Jupiter. Although its predecessor, NASA's Galileo spacecraft, took a death-dive into the gas giant it didn't detect any signs of water in its atmosphere. Why? Fran Bagenela, of the University of Colorado, told a group of scientists at the recent meeting of the American Astronomical Society in Anchorage, Alaska, that the Galileo probe fell at the boundary between one of the brown atmospheric zones and white belts that form a striped pattern across the planet's face. This gap region could have been unusually dry, she added. Now it's up to Juno to investigate when it enters orbit around Jupiter in 2016."

The debate between creationists and proponents of evolution isn't ending any time soon, but now some creationists have a secret weapon, "Nessie!" Certain fundamentalist schools in Louisiana plan to teach children that the Loch Ness monster is real in a bid to disprove Darwin's theory of evolution. From the article: "One ACE textbook – Biology 1099, Accelerated Christian Education Inc – reads: 'Are dinosaurs alive today? Scientists are becoming more convinced of their existence. Have you heard of the "Loch Ness Monster" in Scotland? "Nessie" for short has been recorded on sonar from a small submarine, described by eyewitnesses, and photographed by others. Nessie appears to be a plesiosaur.' Another claim taught is that a Japanese whaling boat once caught a dinosaur. It's unclear if the movie Godzilla was the inspiration for this lesson."

Zothecula writes "For over 30 years, the $250,000 for the American Helicopter Society's Igor I. Sikorsky Human Powered Helicopter Competition prize has looked decidedly secure, but Gamera II has changed all that. Last week, Clark School of Engineering team pilots came close to breaking one of the competition's major milestones. Ph.D. candidate from Kyle Gluesenkamp from the School's mechanical engineering department, hand-cranking and pedaling like his life depended on it, managed to keep the huge quad-rotor craft aloft for 50 seconds, an impressive new world record that's currently awaiting validation by the National Aeronautic Association (NAA)." We previously covered their attempt to break the record last May.

MrSeb writes "American and Israeli researchers have used twisted, vortex beams to transmit data at 2.5 terabits per second. As far as I can discern, this is the fastest wireless network ever created — by some margin. These twisted signals use orbital angular momentum (OAM) to cram much more data into a single stream, without using more spectrum. In current state-of-the-art transmission protocols (WiFi, LTE, COFDM), we only modulate the spin angular momentum (SAM) of radio waves, not the OAM. If you picture the Earth, SAM is our planet spinning on its axis, while OAM is our movement around the Sun. Basically, the breakthrough here is that researchers have created a wireless network protocol that uses both OAM and SAM. In this case, Alan Willner and fellow researchers from the University of Southern California, NASA's Jet Propulsion Laboratory, and Tel Aviv University, twisted together eight ~300Gbps visible light data streams using OAM. For the networking nerds, Willner's OAM link has a spectral efficiency of 95.7 bits per hertz; LTE maxes out at 16.32 bits/Hz; 802.11n is 2.4 bits/Hz. Digital TV (DVB-T) is just 0.55 bits/Hz. In short, this might just be exactly what our congested wireless spectrum needs."

An anonymous reader writes "As a calculus professor for a small undergraduate institution, I normally lecture students who are majoring in the natural (or 'hard') sciences, such as mathematics, physics, and computer science. In fact, I have done so for almost thirteen years. However, for the first time this fall semester, we have a shortage of professors on our hands. As a result of this, I have been asked to teach a general education statistics class. Such classes are a major requirement for the large psychology student body we have here. I have never lectured social science students in any mathematics-related classes. My question to the Slashdot community is as follows: What are your experiences with teaching natural science classes to social science students? How is the experience the same or different in comparison to natural science students who may be more adept to the nuances of mathematics and other similar fields?"

The L.A. Times reports on a study by UCLA climate researchers who conclude, based on supercomputer analysis of a model "2,500 times more precise than previous climate models for the region" that the area around L.A. will experience more (and more extreme) hot spells in decades to come. From the article: "The study, released Thursday, is the first to model the Southland's complex geography of meandering coastlines, mountain ranges and dense urban centers in high enough resolution to predict temperatures down to the level of micro climate zones, each measuring 2 1/4 square miles. The projections are for 2041 to 2060. Not only will the number of hot days increase, but the study found that the hottest of those days will break records, said Alex Hall, lead researcher on the study by UCLA's Institute of the Environment and Sustainability."

ananyo writes "A report presented at the 2012 BIO International Convention in Boston, Massachusetts suggests that patents do not stifle progress when they occur at early phases of research, as some have suggested. Over the past decade, increases in patents have been matched by growth in the biotech and pharmaceutical sectors in India, Brazil, Singapore and other countries with emerging economies. The strength of patent rights can be quantified in an index ranging from 0 (no patent rights) to 5 (very strong). Over time, the countries that U.S. biotech and pharmaceutical companies have invested in have moved up the IP barometer, the report (PDF) says."

A few days back, the crew of the Shenzhou 9 were along for the ride as their craft docked to — or rather, was docked to — an orbiting module. On Sunday, the docking procedure was repeated, but under the direction of the Chinese astronauts themselves rather than controllers on the ground.

Peristaltic writes "Scientists at the U.S. Department of Agriculture are trying to determine if an unexpected mutation in a popular GM grass, Tifton 85, is responsible for the sudden deaths of a small herd of cattle in Elgin, Texas three weeks ago. The grass has been used for grazing since 1992 without incident, however after a severe drought last year in Texas, the grass started producing cyanide in sufficient quantities to kill a small herd of cattle in Elgin, Texas. Testing has found the cyanide-producing grass in nearby fields as well." Update: 06/23 22:59 GMT by T : Reader Jon Cousins writes with a correction that means the headline above is inaccurate for including "GM." Tifton 85, he writes, is "absolutely not genetically modified. It's a conventionally bred hybrid."

sciencehabit writes "A new video released by the The European Commission — ostensibly aimed at getting girls interested in science — is drawing widespred condemnation from around the web for its depiction of female scientists as sexy models strutting into the frame in high heels and short skirts. A male scientist watching them from behind his microscope doesn't seem to mind that none of them are wearing safe lab attire—he just pops his glasses on for a better look. The rest of the video is a mish-mash of heels, nail polish, lipstick, and sexily smoldering Erlenmeyer flasks, arbitrarily punctuated by girly giggles." The Commission denies that the video (since pulled) was a parody, but they've certainly set the bar high for anyone who wanted to make an actual parody.

An anonymous reader writes "People can be trained to forget specific details associated with bad memories, according to breakthrough findings that may lead the way for the development of new depression and post-traumatic stress disorder therapies. New study (abstract), published in the Journal of Experimental Psychology: Learning, Memory and Cognition, reveals that individuals can be taught to forget personal feelings associated with an emotional memory without erasing the memory of the actual event."

astroengine writes "The two planets circling Kepler-36, a sun-like star in its senior years, are as different as Earth and Neptune. But unlike the hundreds of millions of miles that separate our solar system's rocky worlds from its gas giants, Kepler-36's brood come as close as 1.2 million miles (1.9 million kilometers, or 0.01 AU) from one another — about five times the distance between Earth and the moon. This is yet another weird exoplanetary star system that defies conventional wisdom when it comes to planetary formation theories. 'The weirder they are, the more scientifically interesting they are,' Steve Howell, deputy project scientist with NASA's Kepler space telescope, told Discovery News."

An anonymous reader writes "The second of the two controversial bird flu studies once considered too risky to publish in fears that they would trigger a potentially devastating global influenza epidemic was published Thursday. The study describes how scientists created H5N1 virus strains that could become capable of airborne transmission between mammals. Scientists said that the findings, which had been censored for half a year, could help them detect dangerous virus strains in nature."

An anonymous reader writes "For decades, researchers have been trying to build boats, submarines, and torpedoes that make use of supercavitation — a bubble layer around the hull that drastically reduces friction and enables super-fast travel. Now a company in New Hampshire called Juliet Marine Systems has built and tested such a craft, and says it is the world's fastest underwater vehicle. The ship, called the 'Ghost,' looks like two supercavitating torpedoes with a command module on top, and can carry 18 people plus weapons and supplies. The company is in talks with the U.S. Navy to build a version of the ship that can guard the fleet against swarm attacks by small boats. The question is how well it really works, and whether it can be used reliably and effectively on the high seas."

tekgoblin writes "Well this is pretty awesome, Valve has made an entrance into the education sector. They plan to release a new version of Steam for education uses in schools. Valve will call this service Steam for Schools, an education version of the Steam client that allows administrators to limit what its users can access. The idea of Steam for Schools is to use the platform as a teaching aid. Valve has already put together a number of educational lesson plans for using Portal 2 and its level editor to teach math and physics."

chicksdaddy writes "Software failures were behind 24 percent of all the medical device recalls in 2011, according to data from the U.S. Food and Drug Administration's (FDA's) Office of Science and Engineering Laboratories (OSEL). The absence of solid architecture and 'principled engineering practices' in software development affects a wide range of medical devices, with potentially life-threatening consequences, the FDA warned. In response, FDA told Threatpost that it is developing tools to disassemble and test medical device software and locate security problems and weak design."
