NC Planners May Be Barred From Using Speculative Sea Level Rise Predictions 419

ideonexus writes "Republicans in North Carolina are floating a bill that would force planners to only consider historical data in predicting the sea-level rise (SLR) for the state as opposed to considering projections that take Global Warming into account. NC-20, the pro-development lobbying group representing twenty counties along the NC coast, is behind the effort and asserts that the one-meter prediction would prohibit development on too much land as opposed to SLR predictions of 3.9 to 15.6 inches." Scientific American has an acerbic take on the bill.

Soda Ban May Hit the Big Apple 1141

An anonymous reader writes "NYC residents may soon be unable to buy big gulps. In an effort to curb obesity, New York City's Mayor Bloomberg is seeking a ban on oversized sodas in restaurants, movie theaters and stadiums officials said on Wednesday. 'Obesity is a nationwide problem, and all over the U.S., public health officials are wringing their hands saying, "Oh, this is terrible,"' Mayor Bloomberg said. 'New York City is not about wringing your hands; it's about doing something. I think that's what the public wants the mayor to do.'"

Video Backyard Brains Can Help Satisfy Your Inner Frankenstein (Video) Screenshot-sm 199

Did you know that cockroaches have such large nerves in their legs that you can poke into their legs almost at random and hit a nerve with an electrode so you can stimulate that leg with hip-hop music and and watch it move? And that you can easily order the parts to do this at home or at school? You can. And supplies to perform many other neuroscience experiments, too. Amaze your friends! Learn how neurons work! Gross out squeamish people! All that (and more) is what Backyard Brains is about.

Open-Source Mini Sub Can Be Made On the Cheap 62

An anonymous reader writes "Eric Stackpole is a NASA engineer and avid outdoorsman. He is the chief designer of a cheap, portable underwater ROV that could change the way we explore our oceans. And he wants to make it so cheap and easy to build that anyone can do it. The device in question is the OpenROV, a small, lasercut contraption powered by several C-cells, a small, cheap computer and a webcam. Right now the price per vehicle is around $500-$600, As with all open source hardware projects, further development will likely drastically reduce the price. Or you can buy a kit for $750 and support the project, once the Kickstarter gets going."

Ore-Sniffing Dogs Rediscovered By Mining Industry 78

An anonymous reader writes "In the 60s and 70s Sweden, Russia and Finland were the foremost players in the game of ore dogs, using dogs to sniff out ore deposits for mining. The technique was forgotten in the last century, but this article shows they're now being used again to discover ore deposits. From the article: 'The keen noses of sniffer dogs are proving so successful at locating ore that even the mining giants are sitting up and taking notice. Berenice Baker talks to Peter Bergman, geologist and CEO of the Swedish company OreDog, about his plans to turn the canine skills into a multi-million dollar global industry providing exploration services for the mining industry while offering a Google-like working environment for staff.'"

Milky Way's Black Hole Wasn't Always Such a Wimp 83

scibri writes "Sagittarius A*, the dormant supermassive black hole that lies at the center of our galaxy, was much more active not that long ago. Astronomers using the Fermi Gamma-ray Space Telescope have picked up some faint gamma-ray signals that suggest Sagittarius A* was emitting a pair of powerful gamma-ray jets like other galactic black holes as recently as 20,000 years ago (arXiv paper). If our black hole was more active in the past, it could explain why Sagittarius A* seems to be growing about 1,000 times too slowly for it to have reached its current mass of about four million solar masses since the Galaxy formed about 13.2 billion years ago."

Everything You Need To Know About the June 5/6 Venus Transit 55

The Bad Astronomer writes "Next week, on June 5/6, there will be the last Venus transit across the face of the Sun until the year 2117. There are dozens of sites issuing press releases about it — online resources, watching live, viewing advice — so I've collected them into a single blog post with tons of links and my own advice on how to observe this (most likely) last-in-a-lifetime event. This complements the previous article on Slashdot from a few weeks ago."

Mathematicians Show Why Bubbles Sink in Nitrogen-Infused Stouts 55

SicariusMan writes "The age old question: do Guinness and other stouts' bubbles really sink, or is it an optical illusion? Well, some mathematicians have figured it out." Full paper via arXiv; From the article: "To analyze the effect of different glass shapes, the mathematicians modeled Guinness beer containing randomly distributed bubbles in both a pint glass and an anti-pint glass (i.e., an upside-down pint). An elongated swirling vortex forms in both glasses, but in the anti-pint glass the vortex rotates in the opposite direction, causing an upward flow of fluid and bubbles near the wall of the glass."

GRAIL Probes Complete Primary Mission Ahead of Schedule 43

Zothecula writes with an update on NASA's lunar mapping probes. From the article: "After entering orbit around the Moon at the start of the year, NASA's twin GRAIL probes, Ebb and Flow, have completed their primary mission to study the Moon's interior structure ahead of schedule. Operating around the clock since March 8, NASA says the spacecraft have provided unprecedented detail about the interior structure and evolution of the Moon and the data they have gathered will provide insights into how Earth and its rocky neighbors in the inner solar system developed." And their extended mission? From NASA: "The extended mission goal is to take an even closer look at the moon's gravity field. To achieve this, GRAIL mission planners will halve their current operating altitude to the lowest altitude that can be safely maintained. 'Orbiting at an average altitude of 14 miles (23 kilometers) during the extended mission, the GRAIL twins will be clearing some of the moon's higher surface features by about 5 miles (8 kilometers),' said Joe Beerer of JPL, GRAIL's mission manager."

All Researchers To Be Allocated Unique IDs 164

ananyo writes with information on a new scheme to help uniquely identify authors in the face of ambiguous names. From the article: "In 2011, Y. Wang was the world's most prolific author of scientific publications, with 3,926 to their name — a rate of more than 10 per day. Never heard of them? That's because they are a mixture of many different Y. Wangs, each indistinguishable in the scholarly record. The launch later this year of the Open Researcher and Contributor ID (ORCID), an identifier system that will distinguish between authors who share the same name, could soon solve the problem, allowing research papers to be associated correctly with their true author. Instead of filling out personal details on countless electronic forms associated with submitting papers or applying for grants, a researcher could also simply type in his or her ORCID number. Various fields would be completed automatically by pulling in data from other authorized sources, such as databases of papers, citations, grants and contact details. ORCID does not intend to offer such services itself; the idea is that other organizations will use the open-access ORCID database to build their own services."

Intelsat Signs Launch Contract With SpaceX 167

New submitter jamstar7 writes "Following the success of the Falcon9/Dragon resupply test to the ISS comes the following announcement: 'Intelsat, the world's leading provider of satellite services, and Space Exploration Technologies (SpaceX), the world's fastest growing space launch company, announced the first commercial contract for the Falcon Heavy rocket. "SpaceX is very proud to have the confidence of Intelsat, a leader in the satellite communication services industry," said Elon Musk, SpaceX CEO and Chief Designer. "The Falcon Heavy has more than twice the power of the next largest rocket in the world. With this new vehicle, SpaceX launch systems now cover the entire spectrum of the launch needs for commercial, civil and national security customers."' As of yet, the Falcon Heavy hasn't flown, but all the parts have been tested. Essentially an upgunned Falcon 9 with additional boosters, the Heavy has lift capability second only to the Saturn 5. On top of the four Falcon Heavy launches planned for the U.S. Air Force this year, the Intelsat contract represents the true dawn of the commercial space age."

NASA, ASU Team Finds a New Test For Osteoporosis 46

An anonymous reader writes "The BBC has an article about scientists at NASA who believe that they have found a new test that can detect osteoporosis earlier than existing tests. Their test involved having healthy volunteers confined to bed rest for 30 days; 'the technique was able to detect bone loss after as little as one week of bed rest.' Bone loss is an issue for astronauts as well as people affected by osteoporosis. They expect this test will help detect bone loss as a symptom of osteoporosis, but have not yet done a trial to confirm this. This is another point against anyone who claims NASA, and going to space in general, is a complete waste of money."

Scientific Literacy vs. Concern Over Climate Change 545

New submitter gmfeier writes "An interesting study reported in Nature Climate Change indicates that concern over climate change did not correlate with scientific literacy nearly as much as with cultural polarization. Quoting: 'For ordinary citizens, the reward for acquiring greater scientific knowledge and more reliable technical-reasoning capacities is a greater facility to discover and use—or explain away—evidence relating to their groups’ positions. Even if cultural cognition serves the personal interests of individuals, this form of reasoning can have a highly negative impact on collective decision making. What guides individual risk perception, on this account, is not the truth of those beliefs but rather their congruence with individuals’ cultural commitments. As a result, if beliefs about a societal risk such as climate change come to bear meanings congenial to some cultural outlooks but hostile to others, individuals motivated to adopt culturally congruent risk perceptions will fail to converge, or at least fail to converge as rapidly as they should, on scientific information essential to their common interests in health and prosperity. Although it is effectively costless for any individual to form a perception of climate-change risk that is wrong but culturally congenial, it is very harmful to collective welfare for individuals in aggregate to form beliefs this way.'"

Another Afghan School Poisoned — 160 Girls Hospitalized 474

An anonymous reader writes "Back in April, we discussed news of an anti-education attack on an Afghani school, which poisoned 150 Afghan schoolgirls. Now, a hospital in the same province has admitted 160 more girls who seem to have suffered a similar attack. 'Their classrooms might have been sprayed with a toxic material before the girls entered, police spokesman Khalilullah Aseer said. He blamed the Taliban. The incident, the second in a week's time, was reported at the Aahan Dara Girls School in Taluqan, the provincial capital. The girls, ages 10 to 20, complained of headaches, dizziness and vomiting before being taken to the hospital, said Hafizullah Safi, director of the provincial health department. More than half of them were discharged within a few hours of receiving treatment, Safi said. The health department collected blood samples and sent them to Kabul for testing.'"

Debate Over Evolution Will Soon Be History, Says Leakey 1226

Hugh Pickens writes "According to noted paleoanthropologist Richard Leakey, sometime in the next 15 to 30 years scientific discoveries about evolution will have accelerated to the point that 'even the skeptics can accept it.' 'If you don't like the word evolution, I don't care what you call it, but life has changed. You can lay out all the fossils that have been collected and establish lineages that even a fool could work up. So the question is why, how does this happen? It's not covered by Genesis. There's no explanation for this change going back 500 million years in any book I've read from the lips of any God.' Leakey began his work searching for fossils in the mid-1960s and his team unearthed a nearly complete 1.6-million-year-old skeleton in 1984 that became known as 'Turkana Boy,' the first known early human with long legs, short arms and a tall stature. At 67, Leakey conducts research with his wife, Meave, and daughter, Louise, and the family claims to have unearthed 'much of the existing fossil evidence for human evolution.' Leakey, an atheist, insists he has no animosity toward religion."

Landmark Calculation Clears the Way To Answering How Matter Is Formed 205

First time accepted submitter smazsyr writes "An international collaboration of scientists is reporting in landmark detail the decay process of a subatomic particle called a kaon – information that may help answer fundamental questions about how the universe began. The calculation in the study required 54 million processor hours on the IBM BlueGene/P supercomputer at Argonne National Laboratory, the equivalent of 281 days of computing with 8,000 processors. 'This calculation brings us closer to answering fundamental questions about how matter formed in the early universe and why we, and everything else we observe today, are made of matter and not anti-matter,' says a co-author of the paper."

'Eco-Anarchists' Targeting Nuclear and Nanotech Workers 426

scibri writes, quoting Nature: "A loose coalition of eco-anarchist groups is increasingly launching violent attacks on scientists. A group calling itself the Olga Cell of the Informal Anarchist Federation International Revolutionary Front has claimed responsibility for the non-fatal shooting of a nuclear-engineering executive on 7 May in Genoa. The same group sent a letter bomb to a Swiss pro-nuclear lobby group in 2011; attempted to bomb IBM's nanotechnology laboratory in Switzerland in 2010; and has ties with a group responsible for at least four bomb attacks on nanotechnology facilities in Mexico. Another branch of the group attacked railway signals in Bristol, UK, last week in an attempt to disrupt employees of nearby defense technology firms (no word on whether anyone noticed the difference between an anarchist attack and a normal Wednesday on the UK's railways). A report by Swiss intelligence says such loosely affiliated groups are increasingly working together."

The Race To $1,000 Human Genome Sequencing 153

ericjones12398 writes "Just one decade ago, sequencing an entire human genome cost upwards of $10 million and took about three years to complete. Now, several companies are racing to provide technology that can sequence a complete human genome in one day for less than $1,000. 'A genome sequence for $1,000 was a pipe dream, just a few years ago,' said Dr. Richard Gibbs, director of the Human Genome Sequencing Center at Baylor College of Medicine, 'A $1,000 genome in less than one day was not even on the radar, but will transform the clinical applications of sequencing."
