Fruit Flies Medicate Offspring With Alcohol 64

Posted by Soulskill
from the a-friend-of-mine-does-that-too dept.
Copper Nikus writes "In yet another fascinating example of insects being smarter than we give them credit for, this article describes how fruit flies are able to fight back against deadly wasps by using alcohol. Quoting: 'These wasps lay eggs on the larva or pupa of the flies, and their offspring feed on the animal internally, often killing them in the process. (Flies have larval stages, during which we call them maggots, and pupate just as butterflies do before emerging in their adult form.) Once infected, there isn't much one of the larva can do to get rid of the parasite. Its one option: booze (abstract). Fruit flies, as their name implies, like to dine on fruit, especially during the larval stages. In many cases, that involves ingesting the alcohol that's produced by natural fermentation of rotting fruit (this can approach 20 percent alcohol content). Some species of flies have developed the ability to tolerate this alcohol as they chew through the fruit as maggots. But for most of the wasp species, even moderate levels of alcohol are toxic."

Growing Public Unrest Leads China To Admit To 'Cancer Villages' 174

Posted by Soulskill
from the cheeriest-places-on-earth dept.
eldavojohn writes "A new report from China's environment ministry has resulted in long-overdue self-realizations as well as possible explanations for 'cancer villages.' The term refers to villages (anywhere from 247 to 400 known of them) that have increased cancer rates due to pollution from nearby factories and industry. The report revealed that many harmful chemicals that are prohibited and banned in developed nations are still found in China's water and air. Prior research has shown a direct correlation between industrialization/mining and levels of poisonous heavy metals in water. As a result, an air pollution app has grown in popularity and you can see the pollution from space. China has also released a twelve-year plan for environmental protection."

Flu Shot Doing Poor Job of Protecting Older People This Year 205

Posted by Soulskill
from the thanks-geritol dept.
New submitter Gunilla sends this news from an AP report: "It turns out this year's flu shot is doing a startlingly dismal job of protecting older people, the most vulnerable age group. The vaccine is proving only 9 percent effective in those 65 and older against the harsh strain of the flu that is predominant this season, the Centers for Disease Control and Prevention said Thursday. Health officials are baffled as to why this is so. But the findings help explain why so many older people have been hospitalized with the flu this year. Despite the findings, the CDC stood by its recommendation that everyone over 6 months get flu shots, the elderly included, because some protection is better than none, and because those who are vaccinated and still get sick may suffer less severe symptoms." An anonymous reader adds information about a new drug that treats influenza by hijacking its own infection mechanism. The compound "binds to an enzyme on the surface of the flu virus called neuraminidase. This enzyme is responsible for severing the connection between the flu virus and human cell so it can move on and infect other cells. The new class of drugs — DFSAs — permanently bind to the enzyme, blocking its action and stopping it from spreading further, the journal Science reported (abstract). Currently available antivirals also work by attaching to this enzyme. But DFSAs do so in such a way that the flu virus cannot evolve to be resistant to the drug without rendering itself useless."

First Dedicated Asteroid-Tracking Satellite Will Be Canadian 49

cylonlover writes "In the wake of the meteor blast over Russia and the close-quarter flyby of asteroid 2012 DA14 last week, many people's thoughts have turned to potential dangers from above. It is timely then that the Canadian Space Agency will next week launch NEOSSat (Near-Earth Object Surveillance Satellite), the world's first space telescope for detecting and tracking asteroids, satellites and space debris." The meteor incident in Russia has spurred interested in asteroid defense across the globe; donations are pouring in for asteroid-related projects, government officials are making a show of seeming interested, and researchers are stepping up their efforts. Unfortunately, as a related article at Wired notes, we're still a long, long way from having anything more than early warning systems. Quoting: "A new endeavor coming online in 2015 named the Asteroid Terrestrial-impact Last Alert System Project (ATLAS) will provide an early warning system that could provide one week’s notice for city-destroying 45-meter asteroids and three week’s notice for potentially devastating 140-meter objects. ... A more targeted effort comes from the B612 Foundation, which plans to launch the Sentinel telescope in late 2016. This spacecraft would sit inside the orbit of Venus and constantly be on the lookout for killer asteroids, whichever direction they come from. Sentinel will spot nearly all asteroids 150 meters or larger and identify a significant portion of those down to 30 meters in diameter."

Unnecessary Medical Procedures and the Dangers of Robot Surgery 130

Posted by samzenpus
from the danger-will-robinson dept.
Hugh Pickens writes "The LA Times reports that in a new report aimed at improving healthcare and controlling runaway costs, a coalition of leading medical societies has identified nearly 100 medical procedures, tests and therapies that are overused and often unnecessary. The medical interventions — including early cesarean deliveries, CT scans for head injuries in children and annual Pap tests for middle-aged women — may be necessary in some cases, but are often not beneficial and may even cause harm. 'We are very concerned about the rapidly escalating cost of healthcare,' says Dr. Bruce Sigsbee. 'This is not healthy for the country, and something has to be done.' Each of the specialty medical societies has provided a list of five procedures that physicians and patients should question about the overuse of medical tests and procedures that provide little benefit and in some cases harm. A 2012 report from the independent Institute of Medicine estimated total waste in the system at 30%, or $750 billion a year. 'Millions of Americans are increasingly realizing that when it comes to healthcare, more is not necessarily better,' says Dr. Christine K. Cassel." According to pigrabbitbear, it's the robots we should be wary of. He writes "'We are committed to helping victims of robot surgery receive the medical care and compensation they deserve. As both a lawyer and a licensed medical doctor, Dr. Francois Blaudeau has made it his mission to fight for the victims of traumatic complications as a result of botched robot surgery.' That's the opening salvo from the medical malpractice lawyers who run the slick fear factory of a website, BadRobotSurgery.com. According to the doctor-lawyers behind it—doctor-lawyers like Francois Blaudeau, MD, JD, FACHE, FCLM—'thousands of people have suffered severe and critical complications at the hands of surgical robots. In fact, 'robotic surgery has been linked to many serious injuries and severe complications, including death.'

And federal agencies are bracing for the fiscal impact. Federal agencies and the White House are releasing details about how these cuts will affect their operations. If the cuts take effect, expect fewer inspections to the food supply, cuts to programs that support cleanups at former nuclear plants, and plenty of researcher layoffs, among other things."

from the mr.-fusion dept.
cylonlover writes "If Joseph Zawodny, a senior scientist at NASA's Langley Research Center, is correct, the future of energy may lie in a nuclear reactor small enough and safe enough to be installed where the home water heater once sat. Using weak nuclear forces that turn nickel and hydrogen into a new source of atomic energy, the process offers a light, portable means of producing tremendous amounts of energy for the amount of fuel used. It could conceivably power homes, revolutionize transportation and even clean the environment."

Mosquitoes Beginning To Ignore DEET Repellent 232

Posted by samzenpus
from the we're-doomed dept.
Copper Nikus writes "An article at the BBC makes a shocking claim about mosquitoes. It appears some individual insects in the wild have developed the ability to ignore the very popular DEET repellent after a first exposure. From the article: 'To investigate why this might be happening, the researchers attached electrodes to the insects' antenna. Dr Logan explained: "We were able to record the response of the receptors on the antenna to Deet, and what we found was the mosquitoes were no longer as sensitive to the chemical, so they weren't picking it up as well. "There is something about being exposed to the chemical that first time that changes their olfactory system - changes their sense of smell - and their ability to smell Deet, which makes it less effective."'"

New Process Takes Energy From Coal Without Burning It 365

Posted by samzenpus
from the easy-to-clean dept.
rtoz writes "Ohio State students have come up with a scaled-down version of a power plant combustion system with a unique experimental design--one that chemically converts coal to heat while capturing 99 percent of the carbon dioxide produced in the reaction. Typical coal-fired power plants burn coal to heat water to make steam, which turns the turbines that produce electricity. In chemical looping, the coal isn't burned with fire, but instead chemically combusted in a sealed chamber so that it doesn't pollute the air. This new technology, called coal-direct chemical looping, was pioneered by Liang-Shih Fan, professor of chemical and biomolecular engineering and director of Ohio State's Clean Coal Research Laboratory."

littlesparkvt writes in with news about the possibility of a privately funded Mars mission. "Millionaire Dennis Tito became the first paying customer to make a trip to the International Space Station and now he wants to launch a privately funded mission to Mars in 2018. Dennis paid a reported 20 Million to ride aboard a Russian rocket to the International Space Station and has since stayed out of the spotlight, until now. There’s no word whether the trip will include humans, there will be more information on that fact next week. Considering there is little time to train a crew for the mission the flight in 2018 will most likely be an unmanned probe. There’s also a possibility that the first mission to Mars from this private investor will harbor supplies for future astronauts. Plants and food are a possibility as they would take much less space than a full human crew."

Astronomers Find Planet Barely Larger Than Earth's Moon 71

Posted by Soulskill
from the that's-no-planet dept.
The Bad Astronomer writes "A team of astronomers has announced the discovery of the smallest exoplanet orbiting a Sun-like star yet found: Kepler-37b, which has a diameter of only 3865 kilometers — smaller than Mercury, and only a little bigger than our own Moon. It was found using the transit method; as it orbits its star, it periodically blocks a bit of the starlight, revealing its presence (abstract). Interestingly, the planet has been known for some time, but only new advances in asteroseismology (studying oscillations in the star itself) have allowed the star's size to be accurately found, which in turn yielded a far better determination of the planet's diminutive size. Also, the asteroseismology research was not funded by NASA, but instead crowd funded by a non-profit, which raised money by letting people adopt Kepler target stars."

KermMartian writes "The TI-84 Plus C Silver Edition isn't the first color-screen graphing calculator, or even TI's first color calculator, but it's a refresh of a 17-year-old line that many have mocked as antiquated and overpriced. From an advanced review model, the math features look familiar, solid, and augmented with some new goodies, while programming looks about on par with its siblings. The requisite teardown uncovers the new battery, Flash, ASIC/CPU, and LCD used in the device. Although there are some qualms about its speed and very gentle hardware upgrades beyond the screen, it looks to be an indication that TI will continue this inveterate line for years to come."

You Can Navigate Between Any Two Websites In 19 Clicks Or Fewer 185

from the too-close-for-comfort dept.
An anonymous reader writes "A study done by a Hungarian physicist found that of the billions of websites and over a trillion objects on the web, any given two are separated by no more than 19 clicks. 'Distributed across the entire web, though, are a minority of pages—search engines, indexes and aggregators—that are very highly connected and can be used to move from area of the web to another. These nodes serve as the "Kevin Bacons" of the web, allowing users to navigate from most areas to most others in less than 19 clicks. Barabási credits this "small world" of the web to human nature—the fact that we tend to group into communities, whether in real life or the virtual world. The pages of the web aren't linked randomly, he says: They're organized in an interconnected hierarchy of organizational themes, including region, country and subject area. Interestingly, this means that no matter how large the web grows, the same interconnectedness will rule.'"

Monsanto's 'Terminator' Seeds Set To Make a Comeback 284

Posted by Soulskill
from the i'll-be-back dept.
ananyo writes "Monsanto and other biotechnology firms could be looking to bring back 'terminator' seed technology. The seeds are genetically engineered so that crops grown from them produce sterile seed. They prompted such an outcry that, as Slashdot noted, Monsanto's chief executive pledged not to commercialize them. But a case in the U.S. Supreme Court could allow farmers to plant the progeny of GM seeds rather than buying new seeds from Monsanto, making the technology attractive to biotech companies again. Some environmentalists also see 'terminator' seeds as a way of avoiding GM crops contaminating organic/non-GM crops." Reader 9gezegen adds that Monsanto is getting support, oddly, from parts of the software industry. From the NY Times: "BSA/The Software Alliance, which represents companies like Apple and Microsoft, said in a brief that a decision against Monsanto might 'facilitate software piracy on a broad scale' because software can be easily replicated. But it also said that a decision that goes too far the other way could make nuisance software patent infringement lawsuits too easy to file." The case was heard today; here is a transcript (PDF), and a clear explanation of what the case is about.

'It may be that the universe we live in is inherently unstable and at some point billions of years from now it's all going to get wiped out. This has to do with the Higgs energy field itself,' Joseph Lykken, with the Fermi National Accelerator Laboratory in Batavia, Ill., said.

Update — Sensors Do Not Pick Up North Korean Radioactivity 132

Posted by Soulskill
from the better-than-any-other-radiation-ever-created dept.
Update: 02/19 20:49 GMT by S : The story below has been retracted upon further examination of the research. There has been no detection of radioactivity.
gbrumfiel writes "A global network of sensors has picked up faint traces of radioactive gas that probably seeped from last week's underground nuclear test by North Korea. The detection of xenon-133 in Japan and Russia provides further evidence of the nuclear nature of the test, but offers no hint as to the type of weapon used. Atmospheric modelling by the Central Institute for Meteorology and Geodynamics in Vienna shows that the gas likely seeped from North Korea's test site on 15 February, three days after the original test. That indicates that the test was well sealed deep underground."
