Samsung Galaxy S III mini adds 50 euro premium for NFC in Finland, coming to the UK this month
If you had planned to S-Beam your media around on Samsung's Galaxy S III mini, only to be disappointed by the lack of Near Field Communication on our UK review model, then we've got some good news for all twelve of you. Yes, Samsung has announced that Brits will be treated to an NFC iteration before the end of this particularly chilly January and it will arrive across the major carriers and in phone stores both online and real. While the announcement didn't arrive with a price tag, we've been tipped off to some pricing at Finnish retailer Gigantti, where the NFC version rings in at 349 euros. Sidestep the contactless communication, however, and you'll only have to pay 299 euros. There's the choice of both blue and white finishes on either model, but you'll still have to decide whether tappable file transfer and sharing warrants that 50 euros ($67) extra.
SAMSUNG ANNOUNCES AVAILABILITY OF GALAXY S III MINI WITH NFC
New NFC variant set to hit shops at end of January
21st January 2013, London, UK - Samsung Mobile UK today announced that an NFC-enabled version of the Galaxy S III Mini smartphone will be available to buy in the UK from the end of January.
Owners of the new Galaxy S III Mini will be able to share content, such as photos, videos and music, much faster and more easily. Its S Beam feature allows a 10MB music file to be shared in just two seconds by simply tapping on another S Beam-enabled device, such as the Galaxy S III or Galaxy Note II, even without a Wi-Fi or cellular signal. By combining NFC and Wi-Fi Direct, S Beam is capable of sending larger files between phones, such as images, videos and music tracks.
The Galaxy S III Mini is powered by Android[TM] 4.1 (Jelly Bean) and packed with many of the same features available on the Galaxy S III, including S Voice which people can use to tell the phone to wake up, answer an incoming call, or even take a photo, and Direct Call which allows customers to automatically call someone they've just received a text by simply lifting the phone to their ear.
Simon Stanford, Vice President, Telecommunications & Networks, Samsung UK and Ireland said: "
"NFC technology and the digital wallet started to gain significant traction in 2012, particularly in the run up to the Olympics. It's an exciting time in the mobile market watching the next phase of its evolution take shape, so we're happy to announce that we are bringing these new experiences to our customers through our growing number of NFC-enabled devices."
The Galaxy S III Mini will be available to buy in the UK across all major networks, key high street and out of town electrical retailers and online retailers from the end of January.

Overlooked ugly cholesterol causes heart disease, study suggests
Jan. 21, 2013 ? The risk of ischemic heart disease -- the leading cause of death worldwide -- is three times higher in persons with high levels of the so-called 'ugly' cholesterol. This is the finding of a new study of 73,000 Danes, which is shedding light on a long debate on this topic. The results have just been published in the Journal of the American College of Cardiology.
Most individuals are aware that high cholesterol is life-threatening. But very few know which type of cholesterol is the most frequent killer. Cholesterol is divided into 'the good' HDL cholesterol, 'the bad' LDL cholesterol and 'the ugly' cholesterol. It is the so-called 'ugly cholesterol' -- also called 'remnant cholesterol' -- that is a really bad guy.
"LDL cholesterol or 'the bad' cholesterol' is of course bad, but our new study reveals that the ugly cholesterol likewise is the direct cause of atherosclerosis resulting in ischemic heart disease and early death. By examining 73,000 persons, we found that an increase in the ugly cholesterol triples the risk of ischemic heart disease, which is caused by lack of oxygen to the heart muscle due to narrowing or blocking of the coronary arteries," says Professor B?rge Nordestgaard, Chief Physician at Copenhagen University Hospital and Clinical Professor at the Faculty of Health and Medical Sciences at University of Copenhagen.
"I hope that this new knowledge will lead to better preventive treatment including lifestyle changes, as more than one in five individuals in affluent countries suffers from high ugly cholesterol. We also hope that the pharmaceutical industry will develop new drugs targeted specifically at raised ugly cholesterol levels," he emphasises.
Widespread disease worldwide
In Denmark alonhttps://www.sciencedaily.com/cms/e, 20,000 persons are diagnosed with ischemic heart disease every year, and some 150,000 Danes are currently affected by the disease. According to World Health Organization estimates, 17 million people die yearly from cardiovascular disease -- the most frequent cause of death in the world. Ischemic heart disease is the most common cardiovascular disease.
"High ugly cholesterol is the result of high blood levels of normal fat (triglycerides). The most important cause of high ugly cholesterol is overweight and obesity. Persons with high ugly cholesterol should therefore be advised to lose weight, but drugs such as statins and fibrates may also lower levels of ugly cholesterol in the blood," says B?rge Nordestgaard.
Samples from 73,000 Danes with mutations
Anette Varbo, physician and PhD student at Copenhagen University Hospital, has been part of the research team behind the new findings. She says that the findings shed light on a long-standing debate among researchers on the so-called triglycerides, atherosclerosis and cholesterol.
"To be able to examine the relationship between ugly cholesterol and heart disease, we have used blood samples from persons having a mutation which means that they suffer from high ugly cholesterol their entire life. The research findings do therefore not depend on their lifestyle patterns in general. Unhealthy lifestyle factors such as smoking, fatty foods and overweight all increase the risk of heart disease, and the blood samples from persons having these mutations thus give the most accurate results," says Anette Varbo.
The scientific article is based on the following three population studies: the Copenhagen General Population Study, the Copenhagen City Heart Study and the Copenhagen Ischemic Heart Disease Study.

US Attorney defends Aaron Swartz prosecution
1 hr.
The U.S. attorney who directed the prosecution of Internet activist Aaron Swartz, who took his life last Friday, made her first public comments?about the case, saying her office's "conduct was appropriate in bringing and handling" the charges.
"As a parent and a sister, I can only imagine the pain felt by the family and friends of Aaron Swartz, and I want to extend my heartfelt sympathy to everyone who knew and loved this young man," said Carmen M. Ortiz, U.S. Attorney for Massachusetts, in a statement.?
"I know that there is little I can say to abate the anger felt by those who believe that this office's prosecution of Mr. Swartz was unwarranted and somehow led to the tragic result of him taking his own life."
The U.S. Attorney's office, and?Ortiz, specifically, are under fire for bringing?the case against Swartz, including an online petition effort to oust her.?
Swartz, 26,?was a passionate advocate for making public documents?and?as much information as possible available on the Web.?He?was?indicted in 2011?by the federal government on charges of wire fraud and computer fraud.?In an attempt to provide free access to JSTOR, a subscription service for science and literacy journals on MIT's network, Swartz downloaded nearly the entire library of 4.8 million articles and documents to make it publicly accessible.
"Aaron's death is not simply a personal tragedy. It is the product of a criminal justice system rife with intimidation and prosecutorial overreach,"?Swartz's family and partner said?in?a?statement?last?weekend.
Ortiz said that is not the case. "The career prosecutors handling this matter took on the difficult task of enforcing a law they had?taken an oath to uphold, and did so reasonably,"?she?said?in?the?statement.?
"The prosecutors recognized that there was no evidence?against Mr. Swartz indicating that he committed his acts for personal financial gain, and they recognized?that his conduct????while a violation of the law????did not warrant the severe punishments authorized by?Congress and called for by the Sentencing Guidelines in appropriate cases."
Ortiz?said?discussions?were?ongoing?about?a?sentence?that?would?have?been?"six?months?in?a?low?security?setting,"?and?that?"At?no time did this office ever seek???or ever tell Mr. Swartz's attorneys that it intended to seek???maximum penalties under the law,"?which?could??have?been?several?years?in?prison.
In?the?meantime,?California?congresswoman?Zoe?Lofgren,?a?Democrat?whose?district includes Silicon Valley, is?proposing?a?bill,?dubbed?"Aaron's?Law,"?that?would?change the Computer?Fraud?and?Abuse?Act?that?Swartz?was?charged?under,?to?exclude?terms-of-service?violations.
"It looks like the government used the vague wording of those laws to claim that violating an online service?s user agreement or terms of service is a violation of the CFAA and the wire fraud statute," Lofgren said on?Reddit, where she floated the proposal.?"Using the law in this way could criminalize many everyday activities and allow for outlandishly severe penalties."
Lofgren?said?the?law?should?be?changed?to "prevent what happened to Aaron from happening to other Internet users."

Michigan State University Professor Charles Ballard told an audience at the Detr...
Michigan State University Professor Charles Ballard told an audience at the Detroit Economic Club recently that per-capita earnings in right-to-work states are about $5,000 less than in non-right-to-work states.
What he didn't say was that Michigan's per-capita earnings as a non-right-to-work state were below right-to-work states in 2011.
Those saying that right-to-work per-capita income is higher than non-right-to-work states often don't take into consideration the trends when compared to forced unionization states. Those poorer states were earning less even before right-to-work became an option. In recent decades, right-to-work states have grown faster in population, jobs and income when compared to forced unionization states.
The first states to give workers the freedom to choose whether they want to pay to be in a union as a condition of employment did so in 1947.
States that adopted right-to-work laws didn't become poor because of the law. Most were struggling already. For example, Texas' per capita income was on average $540 from 1929 to 1946, which at that time put it 36 percent below the average per capita income of the states that became non-right-to-work states. In 2011, Texas? per capita income was $40,147 and was just 8 percent below the per capita income of non-right-to-work states.

City lights create sexual early birds
Male blackbirds exposed to nocturnal illumination ready to mate sooner in spring
By Susan Milius
Web edition: January 8, 2013
EARLY BIRD
Male European blackbirds exposed to urban night light levels molted sooner and their sexual development advanced up to a month faster than birds living with dark nights.

SAN FRANCISCO ? City lights can deliver male birds into reproductive readiness weeks ahead of schedule.
Male European blackbirds monitored in a lab under simulated city lighting started secreting increased levels of testosterone and growing their sexual organs up to a month earlier in the spring than birds kept in country-style darkness, Davide Dominoni of the Max Planck Institute for Ornithology in Radolfzell, Germany, reported January 6 at the annual meeting of the Society for Integrative and Comparative Biology.
Dominoni?s colleagues have found that, outside the lab, male blackbirds flying around Munich undergo this growth surge about three weeks earlier than counterparts in a forest just 40 kilometers out of town.
Beginning in December 2010, the researchers exposed captive blackbirds to night light levels typical of urban settings. They estimated those levels by outfitting free-flying blackbirds with light-sensitive devices and averaging the urban light exposure. A winter of lab night light sped up the males? molting and boosted testosterone levels as well as organ development in spring. Continuing the night light treatment through the next winter left the males reproductively shut down in the spring of 2012.
The lab night lights probably kept the birds? seasonal reproductive clocks from resetting at the end of the first breeding season, Dominoni says. That second-year suppression may not be common in the real world, where birds fly around and experience more variety in night lighting, he says. But he sees the lab breeding shutdown as a sign of how big of an impact artificial light might have.
?There?s no shortage of starlings and other birds in cities,? said Jamie Cornelius of the University of California, Davis: Urban birds can reproduce despite artificial lights, and Cornelius says she?d love to know what lets them manage when the lab birds couldn?t.
Maybe the results hold a nugget of inspiration for some kind of light-driven control for nuisance birds, mused Ned Place of Cornell University. Perhaps blasts of illumination in certain urban places on a certain series of nights could discourage overpopulation by less-beloved avian residents.Source: http://www.sciencenews.org/view/generic/id/347417/title/City_lights_create_sexual_early_birds

Gov't spent $18 billion on immigration enforcement
WASHINGTON (AP) -- The Obama administration spent more money on immigration enforcement in the last fiscal year than all other federal law enforcement agencies combined, according to a report on the government's enforcement efforts from a Washington think tank.
The report on Monday from the Migration Policy Institute, a non-partisan group focused on global immigration issues, said in the 2012 budget year that ended in September the government spent about $18 billion on immigration enforcement programs run by Immigration and Customs Enforcement, the US-Visit program, and Customs and Border Protection, which includes the Border Patrol. Immigration enforcement topped the combined budgets of the FBI; Bureau of Alcohol, Tobacco, Firearms and Explosives; Drug Enforcement Administration and U.S. Secret Service by about $3.6 billion dollars, the report's authors said.
Since then-President Ronald Reagan signed the Immigration Reform and Control Act in 1986 ? which legalized more than 3 million illegal immigrants and overhauled immigration laws ? the government has spent more than $187 billion on immigration enforcement. According to the report, "Immigration Enforcement in the United States: The Rise of a Formidable Machinery," federal immigration-related criminal prosecutions also outnumber cases generated by the Justice Department.
The 182-page report concludes that the Obama administration has made immigration its highest law enforcement priority. Critics are likely to bristle over its findings, especially those who have accused the administration of being soft on immigration violators.
"Today, immigration enforcement can be seen as the federal government's highest criminal law enforcement priority, judged on the basis of budget allocations, enforcement actions and case volumes," MPI Senior Fellow Doris Meissner, a co-author of the report, said in a statement released with the report Monday.
The report by MPI's Meissner, Muzaffar Chishti, Donald Kerwin and Clair Bergeron, comes amid renewed interest in immigration reform from Congress and the White House.
In the immediate aftermath of the November election, congressional Republicans suggested the time was right to begin reform talks anew. President Barack Obama, who won a record share of Hispanic voters, renewed a previous pledge to make immigration reform a priority.
In the lead up to the election, Obama made several administrative changes to the immigration system, including launching a program to allow some young illegal immigrants to avoid deportation and work legally in the country for up to two years. His administration also refocused enforcement efforts to target criminal immigrants and those who posed a security threat. And just last week, the administration announced a rule change to allow some illegal immigrant spouses and children of U.S. citizens to stay in the country while they ask the government to waive 3- or 10-year bans on returning to the United States. Immigrants who win the waiver will still need to leave the country to complete visa paperwork, but will be able to leave without fear of being barred from returning to their families for up to a decade. The rule, first proposed last year, goes into effect in March.
Republican lawmakers have widely criticized the policy changes, routinely describing them as "backdoor amnesty." Many of those same lawmakers have said the border needs to be secured before reform can be taken up.
According to the MPI report and Border Patrol statistics, in 2011 agents arrested about 327,000 people at the southern border, the fewest in nearly 40 years. The Homeland Security Department also removed a record 396,906 immigrants that year. In 2012, nearly 410,000 people were removed from the United States.

Properties to be sold in 312 private colonies soon
New Delhi-?The revenue Department of Delhi is all geared up to initiate the sale and purchase of the 312 colonies which are constructed on the private?land. This proposal was recently approved by the?Lieutenant Governor?s office and will be notified by the coming week.
The?revenue?department?had sought permission to allow the sale and purchase of the land based on the khasra number on colonies situated on the private land as per the?proposed revenue.
This decision to do the land transactions will be quite beneficial to the colony residents as they were earlier not allowed to do any sort of land transaction here due to the?issuance?of provisional regularization certificates in 2008.
This step will not just ?help the residents buy and sell their?properties in Delhi but will also result in increased property prices. As per sources, the properties will be registered as per the valid general power of attorney which is registered before October 2011 Supreme Court order.
The private colonies are divided into four categories as per the?revenue department?s proposal. They are divided into colonies which were established on entire private land, the colonies on the private land procured by the government with no actions against the residents and the colonies established on private land procured through paper and an absence of?compensation to farmers by the government and lastly colonies with lands under the gram sabha.
However, only the first three categories are cleared for the sale and purchase followed by a revised plan for lands under the gram sabha.

Time, not money, key investment for success in real estate business ...
Home ? business ? Time, not money, key investment for success in real estate business
THE NATION January 7, 2013 1:00 am
Many people think: "Since I still do not have much money, I can't invest in real estate." And with this attitude, they will never get started, Pichai Chawla said."You should learn first and at one point, money will arrive. Don't wait to have money before getting started. [Because] you will never do it," he said.
The property and stock investment expert, who runs the B2 budget-hotel group as well as property and other businesses in Chiang Mai, said what a would-be rich person needed to invest was time.
"Go to see the properties," he said. "You have to do a practical study. After visiting 50-100 places, you will become knowledgeable."
American real-estate billionaire Donald Trump has suggested that investors start by visiting 100 properties, Pichai said.
Through visiting a lot of properties, one will learn through observing and comparing the assets, and consequently being able to distinguish good from bad real estate.
"The point is whether you can find a good thing at a good price. And then, even if you don't have money, you can present it to the bank; some of them can lend to you up to 90 per cent [of the property's appraised value]. Or you approach your friends for a joint investment, or sell it to them for a commission," he said.
Importantly, to get rich from property investment, Pichai suggested that people make regular visits to inspect real-estate sites as part of their lifestyles.
"Instead of wasting your money shopping, you can go to see properties during your free time," he said.
BILLIONAIRES' SECRETS
Pichai believes everyone can profit from real estate. Not all of the rich people in this world are particularly smart.
"There are plenty of factors: emotion, fear, luck," he said. "You see, most of [the wealthy] don't have a PhD. But they have practical knowledge, the courage to take risks, and the ability to control their minds. Sometimes, knowing too much prevents you from doing anything."
Pichai said a winner in business was usually the one who understood and could overcome psychological obstacles. "Suffering losses is part of the process of getting rich. There is a deep correlation between the times of problems and success.
"Location is certainly an important factor but it also depends on the kind of project one is developing. It would be a mistake for the developer of a five-star hotel project to be stingy on land cost, for instance.
"An excellent piece is priced at Bt28 million, whereas a modest one is offered for Bt15 million ... Sometimes, I will go for the latter. It depends on how you weigh the pros and cons. But the important thing is what are you developing. As a three-star-hotel developer that sells our rooms for Bt500 a night, location is not of much importance to us," he said.
Pichai said he personally preferred property over stock investments, since the former involved fewer psychological factors.
"Stock investing appears easier but it is in fact more difficult [to succeed]. To invest in real estate, there are a lot of procedures and things you need to study, but the risk is lower," he concluded.

NASA's NuSTAR catches black holes in galaxy web
Jan. 7, 2013 ? NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, set its X-ray eyes on a spiral galaxy and caught the brilliant glow of two black holes lurking inside.
The new image is being released Monday along with NuSTAR's view of the supernova remnant Cassiopeia A, at the American Astronomical Society meeting in Long Beach, Calif.
"These new images showcase why NuSTAR is giving us an unprecedented look at the cosmos," said Lou Kaluzienski, NuSTAR program scientist at NASA headquarters in Washington. "With NuSTAR's greater sensitivity and imaging capability, we're getting a wealth of new information on a wide array of cosmic phenomena in the high-energy X-ray portion of the electromagnetic spectrum."
Launched last June, NuSTAR is the first orbiting telescope with the ability to focus high-energy X-ray light. It can view objects in considerably greater detail than previous missions operating at similar wavelengths. Since launch, the NuSTAR team has been fine-tuning the telescope, which includes a mast the length of a school bus connecting the mirrors and detectors.
The mission has looked at a range of extreme, high-energy objects already, including black holes near and far, and the incredibly dense cores of dead stars. In addition, NuSTAR has begun black hole searches in the inner region of the Milky Way galaxy and in distant galaxies in the universe.
Among the telescope's targets is the spiral galaxy IC342, also known as Caldwell 5, featured in one of the two new images. This galaxy lies 7 million light-years away in the constellation Camelopardalis (the Giraffe). Previous X-ray observations of the galaxy from NASA's Chandra X-ray Observatory revealed the presence of two blinding black holes, called ultraluminous X-ray sources (ULXs).
How ULXs can shine so brilliantly is an ongoing mystery in astronomy. While these black holes are not as powerful as the supermassive black hole at the hearts of galaxies, they are more than 10 times brighter than the stellar-mass black holes peppered among the stars in our own galaxy. Astronomers think ULXs could be less common intermediate-mass black holes, with a few thousand times the mass of our sun, or smaller stellar-mass black holes in an unusually bright state. A third possibility is that these black holes don't fit neatly into either category.
"High-energy X-rays hold a key to unlocking the mystery surrounding these objects," said Fiona Harrison, NuSTAR principal investigator at the California Institute of Technology in Pasadena. "Whether they are massive black holes, or there is new physics in how they feed, the answer is going to be fascinating."
In the image, the two bright spots that appear entangled in the arms of the IC342 galaxy are the black holes. High-energy X-ray light has been translated into the color magenta, while the galaxy itself is shown in visible light.
"Before NuSTAR, high-energy X-ray pictures of this galaxy and the two black holes would be so fuzzy that everything would appear as one pixel," said Harrison.
The second image features the well-known, historical supernova remnant Cassiopeia A, located 11,000 light-years away in the constellation Cassiopeia. The color blue indicates the highest-energy X-ray light seen by NuSTAR, while red and green signify the lower end of NuSTAR's energy range. The blue region is where the shock wave from the supernova blast is slamming into material surrounding it, accelerating particles to nearly the speed of light. As the particles speed up, they give off a type of light known as synchrotron radiation. NuSTAR will be able to determine for the first time how energetic the particles are, and address the mystery of what causes them to reach such great speeds.
"Cas A is the poster child for studying how massive stars explode and also provides us a clue to the origin of the high-energy particles, or cosmic rays, that we see here on Earth," said Brian Grefenstette of Caltech, a lead researcher on the observations. "With NuSTAR, we can study where, as well as how, particles are accelerated to such ultra-relativistic energies in the remnant left behind by the supernova explosion."

NuSTAR is a Small Explorer mission led by Caltech and managed by NASA's Jet Propulsion Laboratory in Pasadena for NASA's Science Mission Directorate in Washington. Orbital Sciences Corporation of Dulles, Va., built the spacecraft. Its instrument was built by a consortium including Caltech; JPL; the University of California (UC) Berkeley; Columbia University; NASA's Goddard Space Flight Center in Greenbelt, Md.; the Danish Technical University in Denmark; Lawrence Livermore National Laboratory in Livermore, Calif.; and ATK Aerospace Systems of Goleta, Calif. NuSTAR's mission operations center is at UC Berkeley, with the Italian Space Agency providing an equatorial ground station located at Malindi, Kenya. The mission's outreach program is based at Sonoma State University in Rohnert Park, Calif. Goddard manages NASA's Explorer Program. Caltech manages JPL for NASA.

New path to more efficient organic solar cells uncovered
Jan. 7, 2013 ? Why are efficient and affordable solar cells so highly coveted? Volume. The amount of solar energy lighting up Earth's land mass every year is nearly 3,000 times the total amount of annual human energy use. But to compete with energy from fossil fuels, photovoltaic devices must convert sunlight to electricity with a certain measure of efficiency. For polymer-based organic photovoltaic cells, which are far less expensive to manufacture than silicon-based solar cells, scientists have long believed that the key to high efficiencies rests in the purity of the polymer/organic cell's two domains -- acceptor and donor. Now, however, an alternate and possibly easier route forward has been shown.
Working at Berkeley Lab's Advanced Light Source (ALS), a premier source of X-ray and ultraviolet light beams for research, an international team of scientists found that for highly efficient polymer/organic photovoltaic cells, size matters.
"We've shown that impure domains if made sufficiently small can also lead to improved performances in polymer-based organic photovoltaic cells," says Harald Ade, a physicist at North Carolina State University, who led this research. "There seems to be a happy medium, a sweet-spot of sorts, between purity and domain size that should be much easier to achieve than ultra-high purity."
Ade, a longtime user of the ALS, is the corresponding author of a paper describing this work in Advanced Energy Materials titled "Absolute Measurement of Domain Composition and Nanoscale Size Distribution Explains Performance in PTB7:PC71 BM Solar Cells." Co-authors are Brian Collins, Zhe Li, John Tumbleston, Eliot Gann and Christopher McNeill.
Solar cell conversion efficiency in polymer/organic photovoltaic cells hinges on excitons -- electron/hole pairs energized by sunlight -- getting to the interfaces of the donor and acceptor domains quickly so as to minimize energy lost as heat. Conventional wisdom held that the greater the purity of the domains, the fewer the impedances and the faster the exciton journey.
Ade and his co-authors became the first to simultaneously measure the domain size, composition and crystallinity of an organic solar cell. This feat was made possible by ALS beamlines 11.0.1.2, a Resonant Soft X-ray Scattering (R-SoXS) facility; 7.3.3, a Small- and Wide-Angle X-Ray Scattering (SAXS/WAXS/) end-station; and 5.3.2, an end-station for Scanning Transmission X-Ray Microscopy (STXM).
Says Collins, the first author on the Advanced Energy Materials paper, "The combination of these three ALS beamlines enabled us to obtain comprehensive pictures of polymer-based organic photovoltaic film morphology from the nano- to the meso-scales. Until now, this information has been unattainable."
The international team used the trifecta of ALS beams to study the polymer/fullerence blend PTB7:PC71BM in thin films made from chlorobenzene solution with and without the addition (three-percent by volume) of the solvent diiodooctane. The films were composed of droplet-like dispersions in which the dominant acceptor domain size without the additive was about 177 nanometers. The addition of the solvent shrank the acceptor domain size down to about 34 nanometers while preserving the film's composition and crystallinity. This resulted in an efficiency gain of 42-percent.
"In showing for the first time just how pure and how large the acceptor domains in organic solar devices actually are, as well as what the interface with the donor domain looks like, we've demonstrated that the impact of solvents and additives on device performance can be dramatic and can be systematically studied," Ade says. "In the future, our technique should help advance the rational design of polymer-based organic photovoltaic films."
This research was primarily supported by the DOE Office of Science, which also supports the ALS.

Razer releases $130 Orbweaver for single-pawed, mechanical PC gaming (video)
Belkin made gamer's hearts flutter with the original N52te speedpad, which Razer took over a couple of years ago and developed into the Nostromo. Now, that peripheral-maker has taken the concept to a new level (and price) with the $130 gadget-tastic Orbweaver gaming keypad. Each of the 20 mechanical keys is programmable with unlimited-length macros, and produces a tactile click when actuated with 2mm travel / 50g of force -- all in the service of max speed to give gamers the drop on foes, according to Razer. Also provided is an eight-way directional thumbpad along with adjustable hand, thumb and palm-rest modules, plus Razer Synapse 2.0 software for re-binding buttons and assigning macros. It's available now for Windows or OS X, so if you're looking for a way to get that tricky drop, roll and fire combo into a single, satisfying click, check the source.
[Thanks, Arjun]

How Crazy Are These Guys?
Reps. Markwayne Mullin, Paul Cook, and Ted Yoho
Mullen for US Congress; United States Congress.
Michele Bachmann almost missed the vote. Members of the 113th House of Representatives were supposed to gather in the chamber by noon then cast their votes for speaker of the House. Two hundred thirty-three Republicans were voting, and only 217 were needed to give John Boehner the job, so it didn?t seem to matter when the chair called Bachmann?s name and the Tea Party star?slightly dimmer since her botched presidential campaign?wasn?t there.
It didn?t matter, until it did. Twelve Republicans voted for someone besides John Boehner, spreading most of the wealth between defeated Rep. Allen West and scowling Majority Leader Eric Cantor. Six other Republicans either missed the vote or sat on their hands to protest Boehner. For a minute or so, it looked like Boehner might need to win the gavel on a second ballot, which hadn?t happened to any speaker in 90 years. And then Bachmann and Rep. Marsha Blackburn, a fellow camera-friendly female conservative, materialized on the floor, motioning to the chair, asking to cast their votes. ?John Boehner,? said an unsmiling Bachmann. Safe.
No one could remember a sloppier election of an incumbent speaker. But there is good, nonschadenfreude-related news: This Congress is a little more mellow than the last one. Early reporting on the 113th has focused on the People Most Likely To Be Like Allen West, because they make good copy, and that?s fair. The Washington Post?s ?members to watch? list includes four Republicans, two of whom opposed Boehner. But 31 of the 35 new Republicans did vote for Boehner after a slapdash ?coup? attempt that counted lots of ?aye? votes as resisters. This assemblage of Republicans is a little smaller, a little more experienced, and even a little more bland. They can be broken into a few distinct groups.
The Tea Party slayers. Last year?s primaries didn?t break like 2010?s. As strong and experienced as the conservative movement was, it lost a few races to more establishment-friendly candidates. Georgia?s Doug Collins, a legislator who?d tried to raise taxes to fund road construction, defeated a radio host who?d been endorsed by Herman Cain and somebody named Sarah Palin. California?s Paul Cook, a relatively conservative assemblyman, was challenged by a Tea Partier who refused to ever raise the debt limit. Cook won, in part, with nearly $1 million from a PAC connected to Mike Bloomberg. North Carolina?s Richard Hudson, a former staffer for a posse of other congressmen, was attacked by the Club for Growth and Red State because his old bosses had, occasionally, compromised.
None of these members softened their views during the primaries. They ran to the right, as one does. Their biggest re-election threats come from Republicans who can run even further, outflanking them on errant votes. But they beat these purists before. Dogma rating: Very low.
The maybe-government-can-work caucus. Oklahoma Rep. Markwayne Mullin is one of very few new Republicans who took a Democratic seat that hadn?t been particularly gerrymandered. (Democrat Dan Boren, probably the most conservative member of his party, had retired.) But he didn?t back the original Ryan plan and preferred one that would have let people over 55 choose Medicare as-is or opt into ?premium support.? Ohio?s David Joyce, a prosecutor who replaced retiring moderate Rep. Steve LaTourette, carbon-copied LaTourette?s positions on tax revenue (fine) and infrastructure spending (more please). Illinois?s Rodney Davis, whose last political job involved securing government grants, took over a district left by an unpredictable conservative. (That would be Tim Johnson, who tried to personally call every constituent during each term.) Dogma rating: Low.
