2 Billion Alien Earths in our Galaxy Alone
Post Date: 2011-03-22 19:43:05 by jwpegler
Roughly one out of every 37 to one out of every 70 sunlike stars in the sky might harbor an alien Earth, a new study reveals. These findings hint that billions of Earthlike planets might exist in our galaxy, researchers added. These new calculations are based on data from the Kepler space telescope, which in February wowed the globe by revealing more than 1,200 possible alien worlds, including 68 potentially Earth-size planets. The spacecraft does so by looking for the dimming that occurs when a world transits or moves in front of a star. Scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif., focused on roughly Earth-size planets within the habitable zones of their stars ...

Apple under fire for 'gay conversion' appApple has come under fire for approving an "app" that offers guidance on how homosexual people can be "cured" and convert to heterosexuality. The "gay cure" application, designed to be used on Apple's hand-held devices, was created by and named after Exodus International, a religious organisation which believes in teaching "freedom from homosexuality through prayer and practicing conversion therapy". The app is offered free on Apple's iTunes online shop and was given a "4+" rating by the company, meaning it is not considered to contain objectionable content. A description of the app ...

snip Researchers from Stanford University and the University of California-Davis published their analysis in the journal Energy Policy. Measuring costs vs benefits The main challenges, say the authors, will be summoning the global will to make the conversion. "There are no technological or economic barriers to converting the entire world to clean, renewable energy sources," said author Mark Jacobson, a Stanford professor, saying it is only a question of "whether we have the societal and political will."

Another Massive Natural Gas Resource Becomes Available
Post Date: 2011-02-26 17:55:07 by Mad Dog
There is a huge reserve of natural gas already discovered, waiting for use and distributed worldwide. The reserves are simply natural gas that is naturally formed with other gases, mostly CO2, in high enough proportion that the natural gas isnt economically useful. How much natural gas is up for conjecture. Contaminated gas reserves havent been logged or reported in great or accurate detail. But estimates range from 16% of the worlds total reserves on up to 30%. Keep in mind these are hypothetical estimates. How much gas has been drilled through and ignored could be far more than these estimates. Whatever the number is it hardly matters, its a huge resource if the ...
UPDATED: The HB Gary Email That Should Concern Us All
Post Date: 2011-02-18 12:07:08 by Skip Intro
As I wrote yesterday , there is a leaked email that has gotten surprisingly little attention around here. It's the one where Aaron Barr discusses his intention to post at Daily Kos - presumably something negative about Anonymous, the hacking group. But that's not the email I'm talking about here. As I also mentioned yesterday, in some of the emails, HB Gary people are talking about creating "personas", what we would call sockpuppets. This is not new. PR firms have been using fake "people" to promote products and other things for a while now, both online and even in bars and coffee houses. But for a defense contractor with ties to the federal government, ...
Computational science ... Error (Global Warming)
Post Date: 2011-02-18 08:19:24 by Biff Tannen
When hackers leaked thousands of e-mails from the Climatic Research Unit (CRU) at the University of East Anglia in Norwich, UK, last year, global-warming sceptics pored over the documents for signs that researchers had manipulated data. No such evidence emerged, but the e-mails did reveal another problem one described by a CRU employee named "Harry", who often wrote of his wrestling matches with wonky computer software. "Yup, my awful programming strikes again," Harry lamented in one of his notes, as he attempted to correct a code analysing weather-station data from Mexico. Although Harry's frustrations did not ultimately compromise CRU's work, his ...
Huge Solar Flare Jams Radio, Satellite Signals: NASA
Post Date: 2011-02-17 12:23:15 by Brian S
WASHINGTON (AFP) A powerful solar eruption that triggered a huge geomagnetic storm has disturbed radio communications and could disrupt electrical power grids, radio and satellite communication in the next days, NASA said. A strong wave of charged plasma particles emanating from the Jupiter-sized sun spot, the most powerful seen in four years, has already disrupted radio communication in southern China. The Class X flash -- the largest such category -- erupted at 0156 GMT Tuesday, according to the US space agency. "X-class flares are the most powerful of all solar events that can trigger radio blackouts and long-lasting radiation storms," disturbing telecommunications ...
Administration to Push for Small ‘Modular’ Reactors
Post Date: 2011-02-13 13:13:53 by Brian S
WASHINGTON The Obama administrations 2012 budget proposal will include a request for money to help develop small modular reactors that would be owned by a utility and would supply electricity to a government lab, people involved in the effort say. The department is hoping for $500 million over five years, half of the estimated cost to complete two designs and secure the Nuclear Regulatory Commissions approval. The reactors would be built almost entirely in a factory and trucked to a site like modular homes. In promoting the reactor, the administrations immediate goal is to help the Energy Department meet a federal target for reducing its carbon dioxide ...

EXOPLANET BONANZA BOOSTS COUNT BY 1,200
Post Date: 2011-02-02 12:28:08 by jwpegler
A NASA telescope taking a nose count of planets in one small neighborhood of the Milky Way registered more than 1,200 candidates, including dozens of planets residing in life-friendly orbits around their parent stars. Scientists have no way of knowing yet if any of the newly discovered planets are solid-body worlds like Earth. But the census, collected by NASA's Kepler Space Telescope after just four months of work, shows that small planets like Earth are much more prevalent than Jupiter-sized worlds and that multiple-planet systems are common. "We think we're seeing about 200 multi-planet systems," astronomer Daniel Fabrycky, with the University of California, Santa ...
GOP Budget Cutters on NASA: 8%…50%…It’s All Good [Full Thread]

GOP Budget Cutters on NASA: 8%
Its All Good Republican budget cutters are preparing to take an axe to the federal budget trunk and anyone (low- income students, rocket scientists, the newly disabled) who gets in the way. Its part of an effort to fulfill a campaign promise to cut $100 billion from domestic discretionary spending. Just how bad would the cuts be for NASA? Legislators are actually targeting $84 billion in cuts, a reduction of 18 percent that would return spending to 2008 levels. NASAs funding would be cut about 8 percent from $18.93 billion to $17.4 billion. However, some Republicans outside of government are advocating a much steeper ...
Oil Spill Dispersants Don't Disappear
Post Date: 2011-01-26 15:07:44 by Brian S
By John Roach When nearly 800,000 gallons of a chemical dispersant were injected into the oil gushing from the busted wellhead on the bottom of the Gulf of Mexico during last year's Deepwater Horizon disaster, nobody knew for sure what would happen. Now, scientists are getting their first answers, and the results are mixed.Tests for a key component of the chemical concoction reveal that the dispersant worked its way into the oil-laden plume in the deep ocean. The dispersant also stayed in the deep ocean and didn't rise toward the surface. But the chemical did not degrade as fast as scientists thought it would."It is hard for me at this point to say whether or not ...

Yellowstone Has Bulged as Magma Pocket Swells
Post Date: 2011-01-24 11:57:36 by Brian S
Yellowstone National Park's supervolcano just took a deep "breath," causing miles of ground to rise dramatically, scientists report. The simmering volcano has produced major eruptionseach a thousand times more powerful than Mount St. Helens's 1980 eruptionthree times in the past 2.1 million years. Yellowstone's caldera, which covers a 25- by 37-mile (40- by 60-kilometer) swath of Wyoming, is an ancient crater formed after the last big blast, some 640,000 years ago. (See "When Yellowstone Explodes" in National Geographic magazine.) Since then, about 30 smaller eruptionsincluding one as recent as 70,000 years agohave filled the caldera ...
The Gaston Glock Story: Why Americans Love European Guns (American capitalism is not as innovative as European socialism)
Post Date: 2011-01-22 16:50:28 by Godwinson
Edward Tenner The Gaston Glock Story: Why Americans Love European Guns Jan 12 2011, 2:11 PM ET < SNIP > Writing in the National Rifle Association's American Rifleman in 2009, Industry Insider columnist Cameron Hopkins provides background: The most significant innovations of the past 30 years, have all come from European gun companies. Even Ruger, the most innovative American gun manufacturer since World War II, has been playing catch up to the likes of Glock, HK, Beretta, Blaser, Sauer, and SIG. In the early 80s, the U.S. Armed Forces conducted a trial to replace the venerable 1911 pistol. An Italian gun came in first (Beretta) and a Swiss-designed, German-made gun was ...
Fruit fly nervous system provides new solution to fundamental computer network problem

With a minimum of communication and without advance knowledge of how they are connected with each other, the cells in the flys developing nervous system manage to organize themselves so that a small number of cells serve as leaders that provide direct connections with every other nerve cell, said author Ziv Bar-Joseph, associate professor of machine learning at ...
2010 Ties 2005 As Warmest Year On Record Worldwide
Post Date: 2011-01-12 12:20:08 by Brian S
(01-12) 08:29 PST WASHINGTON, (AP) -- It's a tie: Government climate experts say last year equaled 2005 as the warmest year on record. According to the National Climatic Data Center, the average worldwide temperature was 1.12 degrees Fahrenheit (0.62 degree Celsius) above normal last year. That's the same as six years ago. Climate experts have become increasingly concerned about rising global temperatures over the last century. Most atmospheric scientists attribute the change to gases released into the air by industrial processes and gasoline-burning engines. In addition, the Global Historical Climatology Network said Wednesday that last year was the wettest on record. Rain and ...
Magnetic North Pole Shifts, Forces Runway Closures at Florida Airport
Post Date: 2011-01-07 13:06:25 by Brian S
The planet's northern magnetic pole is drifting slowly but steadily towards Russia -- and it's throwing off planes in Florida. Tampa International Airport was forced to readjust its runways Thursday to account for the movement of the Earth's magnetic fields, information that pilots rely upon to navigate planes. Thanks to the fluctuations in the force, the airport has closed its primary runway until Jan. 13 to change taxiway signs to account for the shift, the Federal Aviation Administration said. The poles are generated by movements within the Earth's inner and outer cores, though the exact process isn't exactly understood. They're also constantly in flux, moving a ...
Rudeness Is a Neurotoxin
Post Date: 2011-01-06 13:17:20 by Ferret Mike
Americans are rude. I say this not to preach, which is neither my right nor my intention, but as a scientist, a developmental neuroscientist. My concern about American rudeness relates to my scientific research and knowledge about the development of the human brain. My conclusion comes from a recent trip to Japan, and from a reminder of times past, the death of actress Barbara Billingsley, who died Oct. 16, 2010. Billingsley portrayed June Cleaver, the sympathetic and iconic, nurturing mother on the popular 1950s sitcom "Leave It to Beaver." Remember her signature line? "Ward, I'm worried about the Beaver." She confided her concern earnestly to her husband whenever ...
Mass Bird And Fish Deaths Becoming Worldwide Phenomenon
Post Date: 2011-01-05 12:00:21 by Brian S
The mysterious deaths of thousands of birds and fish is no longer confined to the US. About 50 to 100 dead birds were discovered on a highway in central Sweden Tuesday. Scientists don't know what killed the jackdaws but one veterinarian suspects they may have been frightened by fireworks and then run over by a car. "We have received information from local residents last night," County veterinarian Robert ter Horst told the Swedish site The Local. "Our main theory is that the birds were scared away because of the fireworks and landed on the road, but couldn't fly away from the stress and were hit by a car." "We will continue to look at whether there are other ...
Warmest 12-Month Period on Record
Post Date: 2010-12-29 20:37:56 by go65
The 12-month period from December 2009 through November 2010 was the warmest on record globally, according to NASA's Goddard Institute for Space Studies. The average land and ocean combined temperature anomaly for the period was .65 Celsius or 1.17 F above the 1951-1980 global mean, beating the previous warmest 12-month period of +.62 Celsius during 2005. Third place is currently held by 2007 with a reading of +.61 Celsius. The maps below show the northern and southern hemispheric temperature anomalies for the Dec 2009 to Nov 2010 period. Red areas show the warmest regions relative to normal. The GISS regional temperature anomaly graph below shows that most of the warming over the ...
Forecasters Keep Eye On Looming ‘Solar Max’
Post Date: 2010-12-29 11:50:54 by Brian S
The coming year will be an important one for space weather as the Sun pulls out of a trough of low activity and heads into a long-awaited and possibly destructive period of turbulence. Many people may be surprised to learn that the Sun, rather than burn with faultless consistency, goes through moments of calm and tempest. But two centuries of observing sunspots -- dark, relatively cool marks on the solar face linked to mighty magnetic forces -- have revealed that our star follows a roughly 11-year cycle of behaviour. The latest cycle began in 1996 and for reasons which are unclear has taken longer than expected to end. Now, though, there are more and more signs that the Sun is shaking off ...
That snow outside is what global warming looks like
Post Date: 2010-12-20 17:13:02 by go65
There were two silent calls, followed by a message left on my voicemail. She had a soft, gentle voice and a mid-Wales accent. "You are a liar, Mr Monbiot. You and James Hansen and all your lying colleagues. I'm going to make you pay back the money my son gave to your causes. It's minus 18C and my pipes have frozen. You liar. Is this your global warming?" She's not going to like the answer, and nor are you. It may be yes. There is now strong evidence to suggest that the unusually cold winters of the last two years in the UK are the result of heating elsewhere. With the help of the severe weather analyst John Mason and the Climate Science Rapid Response Team, I've ...
NASA: Voyager 1 Nearing Edge Of Solar System
Post Date: 2010-12-13 20:25:18 by Brian S
LOS ANGELES (AP) -- NASA's long-running Voyager 1 spacecraft is barreling its way toward the edge of the solar system. Since 2004, the unmanned probe has been exploring a region of space where solar wind - a stream of charged particles spewing from the sun at 1 million miles per hour - slows abruptly and crashes into the thin gas between stars. NASA said Monday that recent readings show the average outward speed of the solar wind has slowed to zero, meaning the spacecraft is nearing ever closer to the solar system's edge to a boundary known as the heliopause. "It's telling us the heliopause is not too far ahead," said project scientist Edward Stone of the NASA Jet ...
