Scientists Seek Biomarkers For Violence 294

Posted by timothy
from the thoughtcrime-or-a-propensity-thereto dept.
An anonymous reader writes "A Newtown couple, both scientists, who lost their daughter in the school shooting, are wondering whether there were clues in the shooter's physiological makeup — his DNA, his blood, his brain chemistry. They are now involved in a search for biomarkers, similar to those that may indicate disease, for violence. They are raising money to help fund this research, but the effort is running into obstacles, in part, over ethical concerns. 'I'm not opposed to research on violence and biomarkers, but I'm concerned about making too big of a leap between biomarkers and violence,' said Troy Duster, a researcher at the University of California at Berkeley. There is concern that science may find biomarkers long before society can deal with its implications."

Hurricane Sandy a 1-in-700-Year Event Says NASA Study 148

from the nothing-to-see-here dept.
Rebecka writes "Hurricane Sandy, which pelted multiple states in Oct. and created billions of dollars in damage, was a freak occurrence and not an indication of future weather patterns, according to NASA's Goddard Institute for Space Studies via LiveScience. The study (abstract), which calculated a statistical analysis of the storm's trajectory and monitored climate changes' influences on hurricane tracks, claims that the tropical storm was merely a 1-in-700-year event. 'The particular shape of Sandy's trajectory is very peculiar, and that's very rare, on the order of once every 700 years,' said senior scientist at NASA and study co-author, Timothy Hall. According to Hall, the extreme flooding associated with the storm was also due to the storm's trajectory which was described as being 'near perpendicular.' The storm's unusual track was found to have been caused by a high tides associated with a full moon and high pressure that forced the storm to move off the coast of the Western North Atlantic."

from the could-be-worse-could-be-aliens dept.
astroengine writes "A planned six-hour spacewalk outside the International Space Station came to a dramatic and abrupt end on Tuesday when water started building up inside the helmet of Italian astronaut Luca Parmitano. Parmitano and NASA astronaut Chris Cassidy were less than an hour into their spacewalk, their second in a week, when Parmitano reported that his head felt wet. 'My head is really wet and I have a feeling it's increasing,' Parmitano reported to ground control teams at the Johnson Space Center in Houston. Parmitano returned safely to the space station interior, but the cause of the leak was not immediately known."

sciencehabit writes "The tragic opera Rigoletto may move you to tears, but here's a more literal application of the moving power of sound. Sound waves with frequencies just above human hearing can levitate tiny particles and liquid droplets and even move them around, a team of engineers has demonstrated. The advance could open up new ways to handle delicate materials or mix pharmaceuticals."

Researchers Find Some Volcanoes 'Scream' At Increasing Pitches Until They Blow 59

Posted by samzenpus
from the call-of-the-volcano dept.
vinces99 writes "Swarms of small earthquakes often precede a volcanic eruption. They can reach such rapid succession that they create a "harmonic tremor" that resembles sound made by some musical instruments. A new analysis of an eruption sequence at Alaska's Redoubt Volcano in March 2009 shows the harmonic tremor glided to substantially higher frequencies and then stopped abruptly just before six of the eruptions. Scientists at the U.S. Geological Survey's Alaska Volcano Observatory have dubbed the highest-frequency harmonic tremor at Redoubt Volcano 'the screams' because the episodes reach such high pitch compared with a 1-to-5 hertz starting point. Alicia Hotovec-Ellis, a University of Washington doctoral student in Earth and space sciences and an author of two papers examining the phenomenon, has created a 10-second recording and a one-minute recording that provides a 60-times faster representation of harmonic tremor and small earthquakes."

Oldest Lunar Calendar Found In Scotland 51

from the saving-dates dept.
First time accepted submitter eionmac writes "The BBC reports that Archaeologists believe they have discovered the world's oldest lunar 'calendar' in an Aberdeenshire field. Excavations of a field at Crathes Castle found a series of 12 pits which appear to mimic the phases of the moon and track lunar months. A team led by the University of Birmingham suggests the ancient monument was created by hunter-gatherers about 10,000 years ago. The pit alignment, at Warren Field, was first excavated in 2004. The experts who analyzed the pits said they may have contained a wooden post. The Mesolithic calendar is thousands of years older than previous known formal time-measuring monuments created in Mesopotamia. The analysis has been published in the journal Internet Archaeology."

Global Anoxia Ruled Out As Main Culprit In the P-T Extinction 158

Posted by timothy
from the take-a-deep-breath-and-relax dept.
Garin writes "The late Permian saw the greatest mass extinction event of all-time. The causes for this extinction are hotly debated, but one key piece of the puzzle has recently been revealed: while the deep-water environments were anoxic, shallower waters showed clear signs of being oxygenated. This rules out global anoxia, and strongly suggests that other factors, such as the Siberian Traps vulcanism, must have played a dominant role. From the article: 'Rather than the direct cause of global extinction, anoxia may be more a contributing factor along with numerous other impacts associated with Siberian Traps eruption and other perturbations to the Earth system.' See the full research article (behind a paywall) here."

symbolset writes "Discovery News is covering a project by two engineers from the University of Michigan to pair cubesats with tiny ion engines for inexpensive interplanetary exploration. The tiny plasma drive called the CubeSat Ambipolar Thruster (CAT) will ionize water and use it as propellant with power provided by solar cells. In addition to scaling down the size of ion engines they hope to bring down the whole cost of development and launch to under $200,000."

from the pinball-bumpers-zoomed-way-out dept.
aarondubrow writes "Researchers reported results in Nature Communications on a new way of sculpting tailor-made fluid flows by placing tiny pillars in microfluidic channels [abstract; article is paywalled]. The method could allow clinicians to better separate white blood cells in a sample, increase mixing in industrial applications, and more quickly perform lab-on-a-chip-type operation. Using the Ranger and Stampede supercomputers, the researchers ran more than 1,000 simulations representing combinations of speeds, thicknesses, heights or offsets that produce unique flows. This library of transformations will help the broader community design and use sculpted fluid flows."

A Scientist's Quest For Perfect Broccoli 118

Posted by timothy
from the how-about-sweeter-kale dept.
HonorPoncaCityDotCom writes "For all the wonders of fresh broccoli, in most parts of the country it is only available from local growers during the cooler weeks at either end of the growing season, nowhere near long enough to become a fixture in grocery stores or kitchens. But now Michael Moss writes in the NY Times that Thomas Bjorkman is out to change all that by creating a new version of the plant that can thrive in hot, steamy summers like those in New York, South Carolina or Iowa and is easy and inexpensive enough to grow in large volumes. And Bjorkman's quest doesn't stop there: His crucifer is also crisp, subtly sweet and utterly tender when eaten fresh-picked and aims to maximize the concentration of glucoraphanin, a mildly toxic compound used by plants to fight insects that in humans may stimulate our bodies' natural chemical defenses to aid in preventing cancer and warding off heart disease. The Eastern Broccoli Project's goal is to create a regional food network for an increasingly important and nutritious vegetable that may serve as a model network for other specialty crops to help shift American attitudes toward fruits and vegetables by increasing their allure and usefulness in cooking, while increasing their nutritional loads. 'If you've had really fresh broccoli, you know it's an entirely different thing,' says Bjorkman, a plant scientist at Cornell University. 'And if the health-policy goal is to vastly increase the consumption of broccoli, then we need a ready supply, at an attractive price.'"

Yet if the same thing happened today, it would be an utter catastrophe...That's not a lurid sci-fi fantasy. It's a sober new assessment by Lloyd's of London, the world's oldest insurance market. The report notes that even a much smaller solar-induced geomagnetic storm in 1989 left 6 million people in Quebec without power for nine hours.'"

The Savvy Tech Strategy Behind Obamacare 146

Posted by Soulskill
from the i-bet-the-borg-have-low-health-care-costs dept.
snydeq writes "The U.S. health care industry is undergoing several massive transformations, not the least of which is the shift to interoperable EHR (electronic health records) systems. The ONC's Doug Fridsma discusses the various issues that many health care IT and medical providers have raised regarding use of these systems, which are mandated for 2014 under the HITECH Act of 2004, and are all the more important in light of the 2010 Patient Protection and Affordable Care Act, aka Obamacare. Key to the transition, says Fridsma, is transforming health IT for EHRs into something more akin to the Internet, and less like traditional ERP and IT systems. 'I think what we're trying to do is the equivalent of what you've got in the Internet, which is horizontal integration rather than vertical integration,' Fridsma says. 'We've done a lot of work looking at what other countries have done, and we've tried to learn from those experiences. Rather than trying to build this top down and create restrictions, we're really trying to ask, "What's the path of least regret in what we need to do?"'"

Italian Team Cures Wiskott-Aldrich Syndrome With the Help of HIV 109

Posted by Soulskill
from the bending-it-to-our-will dept.
New submitter tchernobog writes "An Italian team funded by Telethon and S. Raffaele of Milan, was able to cure six kids affected by lethal genetic diseases (in Italian, English video): the Wiskott-Aldrich syndrome and the metachromatic leukodystrophy. This is the culmination of a project lasted 15 years, and which cost more than 30M €; the researchers published some preliminary results last year in Nature, and are waiting for the results on more patients to submit another. The really interesting part is: they used a mix of advanced genetic techniques to achieve this result. Firstly, the DNA of a defective cell is corrected with a gene assembled in the lab. This procedure has been very dangerous for the past 20 years: that it can even be used is a good achievement alone. Secondly, the corrected DNA is propagated in the patient's body using a stripped-down version of HIV, of which less than 10% of its original genome remains. Might the feared HIV in reality prove to be salvation for some?"

Math and Science Popular With Students Until They Realize They're Hard 580

Posted by timothy
from the luckily-I-skipped-out-early dept.
First time accepted submitter HonorPoncaCityDotCom writes "Khadeeja Safdar reports in the WSJ that researchers who surveyed 655 incoming college students found that while math and science majors drew the most interest initially, not many students finished with degrees in those subjects. Students who dropped out didn't do so because they discovered an unexpected amount of the work and because they were dissatisfied with their grades. "Students knew science was hard to begin with, but for a lot of them it turned out to be much worse than what they expected," says Todd R. Stinebrickner, one of the paper's authors. "What they didn't expect is that even if they work hard, they still won't do well." The authors add that the substantial overoptimism about completing a degree in science can be attributed largely to students beginning school with misperceptions about their ability to perform well academically in science. ""If more science graduates are desired, the findings suggest the importance of policies at younger ages that lead students to enter college better prepared (PDF) to study science.""

First Exoplanet To Be Seen In Color Is Blue 139

Posted by timothy
from the your-eyes-are-the-color-of-hd-189733-b dept.
ananyo writes "A navy-blue world orbiting a faraway star is the first exoplanet to have its colour measured. Discovered in 2005, HD 189733 b is one of the best-studied planets outside the Solar System, orbiting a star about 19 parsecs away in the Vulpecula, or Fox, constellation. Previous efforts to observe the planet focused on the infrared light it emits — invisible to the human eye. Astronomers have now used the Hubble Space Telescope to observe the planet and its host star. Hubble's optical resolution is not high enough to actually 'see' the planet as a dot of light separate from its star, so instead, the telescope receives light from both objects that mix into a single point source. To isolate the light contribution of the planet, the researchers waited for the planet to move behind the star during its orbit, so that its light would be blocked, and looked for changes in light colour. During the eclipse, the amount of observed blue light decreased, whereas other colours remained unaffected. This indicated that the light reflected by the planet's atmosphere, blocked by the star in the eclipse, is blue."
