Here's the Internet/cable TV ad they ought to run (video)

If only this wasn?t so true. The Internet and cable TV game is rigged in the US, and it?s consumers who lose.

The political class makes out okay because of the big dollars handed out every campaign season. As for the rest of us, we pay far more for cable TV, Internet, phone and cell service in the US than they pay in Europe, for example. Here in France, the phone, TV and Internet package starts at around 30 euros, or $36 ? and the speeds are generally faster than you?ll get as a standard package in most US cities (though, admittedly, customer service tends to be non-existent over here).

John was just telling me that in Washington, DC, he pays $180/month for basic Internet and basic cable TV, has to pay extra for HD (which is hardly some new-fangled technology at this point), and his package doesn?t include any premium movie channels at all. $180, that?s insane.

Thanks, Congress!

FYI ? there?s small amount of language in the video.

ap beatles sgt pepper auction jt 130331 wblog Signed Iconic Beatles Album Auctioned for $290,500Beatles

A copy of The Beatles' "Sgt. Pepper's Lonely Hearts Club Band" album autographed by all four band members has shattered expectations at auction.

The iconic album was sold Saturday for $290,500 by Heritage Auctions in Dallas. It had been listed at $30,000 before the sale. The winning bidder was not identified, but The Associated Press reported the rare item had been sold to a person in the Midwest.

The autographs of the band members were obtained in 1967, the same year the record was issued, according to a letter of authenticity posted on Heritage Auctions' website.

PHOTOS: Expensive Items

Each of the Beatles signed next to his image on the inside spread of the album.

Beatles expert Perry Cox said the piece of memorabilia was "extraordinarily special."

"I consider this to be one of the top two items of Beatles memorabilia I've ever seen - the other being a signed copy of 'Meet the Beatles' [the band's second album released in the U.S.]," he said, according to Heritage Auctions' website.

The album was one of the big draws to Saturday's auctions, which included other entertainment and music memorabilia.

FBI UFO memo is bureau's most viewed public record

FBI UFO memo: The Federal Bureau of Investigation says that its Hottel memo, which reports on an alleged flying saucer sighting, has been viewed nearly a million times since 2011.

By Megan Gannon,?LiveScience.com / March 27, 2013

A single-page March 22, 1950, memo by Guy Hottel, special agent in charge of the Washington Field Office, regarding UFOs is the most viewed document in the FBI Vault, an online repository of public records.

The FBI says its most viewed public record is a memo from 1950 recounting a strange story someone told an agent about three "flying saucers" that were allegedly recovered in New Mexico.

The so-called?Hottel memo?was first released in the late 1970s under the Freedom of Information Act, but it's been viewed nearly a million times since 2011, when the FBI launched an online database of public records called the Vault.

Dated March 22, 1950, the memo was addressed to FBI Director J. Edgar Hoover and written by Guy Hottel, then head of the Bureau's field office in Washington, D.C. Hottel was reporting what an Air Force investigator said that someone else told him about the crashed saucers.

The following details of the report have perhaps fueled the hopes of those who want to believe: "They [the saucers] were described as being circular in shape with raised centers, approximately 50 feet in diameter. Each one was occupied by three bodies of human shape but only three feet tall, dressed in metallic cloth of a very fine texture. Each body was bandaged in a manner similar to the blackout suits used by speed fliers and test pilots."

For the record, FBI officials said in a statement on Monday (March 25) that the Hottel memo "does not prove the?existence of UFOs; it is simply a second- or third-hand claim that we never investigated."

Bureau officials also say there is no reason to believe that the story has anything to do with the infamous?1947 Roswell crash?in New Mexico.?Hoover did actually order his agents?to verify any?UFO sightings?after the?Roswell incident and until?July 1950. That?the Hottel report was never investigated suggests "our Washington Field Office didn't think enough of that flying saucer story to look into it," the FBI statement says.

Airports challenging FAA's planned tower shutdowns

CHICAGO (AP) -- Airport operators are mounting a legal challenge to the Federal Aviation Administration's decision to cut funding for 149 air traffic control towers, accusing the agency of violating federal law meant to ensure major changes at airports do not erode safety.

Several airports are now asking a federal court to halt the plan and compel the FAA to more carefully study the potential safety impact, said Carl Olson, director of the Central Illinois Regional Airport in Bloomington, Ill. He warned that without a more cautious approach, lives will be put at risk by cuts that he contends are arbitrary and the result of reckless political brinkmanship in Washington.

"I think everybody's going to realize what the industry knows, and that is there is a razor thin margin of error in aviation and any diminishment of safety is going to have an immediate and cascading effect," Olson said in an interview Friday. "And all the talk to the contrary won't change that fact."

Olson's airport is among the latest to file a lawsuit this week with the U.S. Circuit Court of Appeals in Washington. The others are Spokane Airports in Washington state, and the operators of Florida airports in Naples, Ormond Beach and Punta Gorda. The court combined the suits into a single case Thursday.

FAA spokeswoman Laura Brown said Friday that the agency could not comment on the pending litigation.

The agency's administrator, Michael Huerta, has stressed that safety remains the FAA's top priority even as it is forced by the budget cutting known as sequestration to trim $637 million for the rest of the fiscal year that ends Sept. 30.

The FAA said it had no choice but to subject most of its 47,000 employees, including tower controllers, to periodic furloughs and to close air traffic facilities run by contractors at 149 small airports with lighter traffic. The first of those closures will happen April 7. Olson's airport is slated to lose its funding May 5.

The tower shutdowns will not mean that airports have to close. All pilots are required to know how to land at un-towered airports and to practice those procedures, which include communicating with other pilots over a shared radio frequency.

But airport directors, pilots and others in the aviation sector say stripping away an extra layer of safety during the most critical stages of flight will elevate risks and at the very least slow years of progress that made the U.S. aviation network the safest in the world.

Lawrence Krauter, director of Spokane International Airport, said he expects more airports and possibly trade associations to join the legal challenge. He said the tower closures amount to one of the most significant changes to the national air system's safety network in recent history and deserve to be studied carefully.

"No one's going to tell you ... that there aren't some contract towers out there that could be closed," Krauter said. "What we're saying is that we think that there needs to be a more reasoned and appropriate process."

Spokane's second and smaller airport, Felts Field, is set to lose its tower funding May 5. Like many of the airports losing funding, it has a busy flight school and serves the area's medical air evacuation operation in addition to handling private aircraft.

Local airport authorities have been scrambling to find the money to keep their towers running once the federal funding runs out. And several of the airport operators wrote to Huerta to ask that he halt the plans and detail exactly what study and review processes, if any, the FAA has carried out.

Olson said he's gotten no response and suspects that no substantive review has been conducted.

"We're not aware of any," Olson said. "There doesn't appear to be any consideration for the individual operations, safety or environmental consequences."

The lawsuits specifically mention the National Environmental Policy Act, which requires extensive review of any airport changes, as well as the Safety Management Systems protocols requiring thorough risk analysis that the FAA must carry out.

"That requirement is not excused" by the budget cuts, Olson said.

DOS emulator brings Raspberry Pi back to the '90s for Doom LAN parties

Raspberry Pi DOS emulator b

Who can forget the first time they obliterated their buddy with a BFG9000 during a spirited Doom game? Raspberry Pi coder Pate wants to resurrect those good times with an rpix86 DOS emulator that opens up the world of retro PC games like the aforementioned FPS pioneer along with Duke Nukem 3D, Jill of the Jungle and others. It works by creating a virtual machine your Dad would be proud of, based on a 40Mhz 80486 processor, 640KB base RAM, 16MB extended memory, 640 x 480 256-color graphics and SoundBlaster 2.0 audio. Of course, the Pi is worlds beyond that with a 700Mhz ARM CPU, 512MB or RAM and HDMI out -- so, most enthusiasts with one of the wee $35 boards will likely be all over hacking it to play those classics.

Sweet 16 for FGCU Eagles: Will 'dunk city' see long-term benefits?

The FGCU Eagles have found their way into the Sweet 16, putting the tiny, new college on the map. As they gear up to face the Gators in their Sweet 16 matchup, will their success yield lasting benefits?

There are Cinderella teams. And then there are the FGCU Eagles, who are gearing up to face the University of Florida Gators Friday night at 10 p.m. on TBS.

By its very nature, the NCAA tournament, a 68-team, single-elimination free-for-all, has seen its fair share of unlikely squads making deep runs, thrusting their home schools suddenly into the national consciousness. Butler, George Mason, and VCU are a few recent examples.

But before last Friday, it was a safe bet that most Floridians didn?t know where Florida Gulf Coast University was, let alone most Americans. That changed over the weekend, when the Eagles, in only their second season as a Division I basketball program, rattled off decisive victories against No. 2 seed Georgetown and No. 7-seed San Diego state, respectively, to become the first 15-seed ever to make it to the Sweet 16. Their rise caught everyone by surprise.

Really, everyone. Nearly 8.2 million NCAA brackets were submitted last week to ESPN?s Tournament Challenge; After the first round, there wasn?t a single perfect bracket left, thanks in large part to the Fort Myers upstarts.?

The New York Times repeatedly called the school ?Gulf Coast College? in a recap of the Friday win over Georgetown; Sunday, San Diego State head coach Steve Fisher called the team that defeated his Aztecs ?Florida State? (though he may have been joking). LeBron James congratulated the team on Twitter, but called the school "Florida Golf Coast" (incorrect, but not totally inaccurate. The school offers a "Golf Management" major). When asked by NPR where FGCU is, and how big it is, Tampa Bay Times journalist John Woodrow Cox replied, ?I didn?t know the answer to any of those questions until Friday.?

Millions of people know the answer to those questions now. Financially, that means a boost for the basketball program that could have lasting benefits for the young college.?

FGCU?s tournament success won?t yield huge bucks directly, especially by the standards of major Division I college sports. Part of the reason: Their winnings have to be shared equally with the other eight members of the Atlantic Sun Conference. If the Eagles lose to the Gators on Friday, they will have played three games in this year?s tournament, earning a $250,000 payout for each, says Victor Matheson, a sports economist and professor at The College of the Holy Cross in Worchester, Mass. ?They get those three tournament shares every year for six years. That?s $3 million in the pocket of the Atlantic Sun Conference, when normally, they get their one automatic bid [and $250,000] every year and that?s it.??

It won?t be exactly rolling in for head coach Andy Enfield, either. Mr. Enfield?s salary from FGCU is a respectable $157,000. According to ESPN?s Daren Rovell, Enfield got an additional $5,000 bonus for making the tournament, a $10,000 bonus for making the round 16, and would make another $25,000 for winning the entire thing.

Compared to the high end of the college coaching pay scale, that?s tiny potatoes: John Calipari, last year?s tournament winner with Kentucky, made $100,000 for making the Sweet 16, $150,00 for making the Final Four, and another $350,000 for winning the title, all on top of his then-$3.8 million annual base salary.?

But a successful basketball program can yield more intangible benefits for universities in terms of revenue, recruitment, and alumni relations. For one, the NCAA tournament is all upside for participating teams, which don?t have to pay for travel expenses or sell tickets. That?s not true of college football?s bowl system, which requires teams to buy up hotel rooms and eat the cost of any unsold tickets, a huge problem for small schools forced to travel far for a postseason berth.

The TV contracts for March Madness are worth about $600 million annually, Mr. Matheson says, and allows the league to pay teams? expenses from the tournament, as well as fund ?every team in every sport across all divisions."

FGCU is enjoying a meteoric boost in visibility and school spirit, at least for now. The school?s athletics website crashed under the weight of unprecedented traffic over the weekend, and much of the school apparel sold online was back-ordered. AP reported phone lines jammed with people seeking tickets to Friday?s game.

It will definitely help the Eagles in Florida?s tough athletic recruiting landscape: The University of Florida, Florida State, and the University of Miami are among the most storied college sports programs in the country, so any little bit of spotlight helps. Academically, the advantages are less clear.

After its 2011 Final Four appearance, Butler saw its application rates jump 41 percent. FGCU, which culls 92 percent of its students from Florida, could see a similar jump and a more varied pool of applicants, though Matheson warns. ?You may get a lot more shoppers but no more buyers, and you may not get any better students. Those who would choose based on that probably aren?t? better students.

There?s some evidence that sports success increases alumni giving, and FGCU has everything to gain in that department: The school has only been up and running since 1997, and its annual endowment is around $50 million (UF?s, meanwhile, is about $1.3 billion). But Matheson warns that donations inspired by the basketball program will probably end up there, and won?t result in any extra money for academics.

Still, he says, athletics are a good way for small colleges like FGCU to build an identity and better reach out to their student body and the community at large. At the very least, the Eagles? high-flying tournament run, full of dancing, dunks, and decisive victories, have given the school and the city of Fort Myers a personality that, to the rest of the nation, looks like a whole lot of fun. Indeed, Fort Myers has fully embraced the Eagles, even putting #dunkcity below the city's name on every page of its tourism website, cityftmyers.com.?

Coach Enfield, meanwhile, can probably expect a pay raise. According to naplesnews.com, FGCU officials have already met to discuss doubling his salary, and his name is being bandied about for the vacant head coaching job at UCLA.

Five genetic variations increase risk of ovarian cancer

Mar. 27, 2013 ? An international research collaboration has found five new regions of the human genome that are linked to increased risks for developing ovarian cancer. Duke Medicine researchers played a leading role analyzing genetic information from more than 40,000 women.

The findings are published in four studies, two appearing in the journal Nature Communications and two in Nature Genetics on March 27, 2013. The research is being published as part of a coordinated release of new data from the Collaborative Oncological Gene-environment Study (COGS), an international effort to identify genetic variations that make certain people susceptible to developing breast, prostate and ovarian cancers.

According to the National Cancer Institute, ovarian cancer accounts for 3 percent of all cancers in women and is the leading cause of death among cancers of the female reproductive system. This is due to the lack of early symptoms or effective screening tests.

Inherited mutations in the BRCA1 and BRCA2 genes dramatically increase ovarian cancer risk. Genetic testing for BRCA1 and BRCA2 mutations can identify women who would benefit most from surgery to prevent ovarian cancer, but this is relevant to less than 1 percent of the population. Other genetic variants that are more common may also affect ovarian risk. The Ovarian Cancer Association Consortium previously described six such genetic differences and now the COGS project has found five more.

"Because ovarian cancer is relatively uncommon, it is critically important to identify subsets of women at increased risk," said senior coauthor Andrew Berchuck, MD, director of the division of gynecologic oncology at Duke Cancer Institute. "Although the common genetic risk variants for ovarian cancer discovered thus far are not strong enough to use in practice, this may become a reality as additional variants are discovered. This could facilitate development of ovarian cancer screening and prevention strategies directed towards women most likely to benefit."

"Our hope is that these genetic variants, along with established epidemiologic factors, such as reproductive history, will not only enhance our ability to predict which women are at increased risk for developing this highly fatal disease, but will also provide new insight into the underlying biology and pathogenesis of ovarian cancer," said epidemiologist Joellen Schildkraut, PhD, director of the Cancer Control and Population Sciences program at Duke Cancer Institute. She is a senior coauthor of one of the Nature studies and the principal investigator of the North Carolina Ovarian Cancer Study, one of the studies that contributed data to this discovery.

"Because of the large number of study subjects, we were able to determine that some genetic variants were important to specific subgroups of ovarian cancer, suggesting possible differences in the underlying cause of these subtypes," Schildkraut said.

Additional studies on the biology of these genetic variants could help researchers develop new tests to predict which women are at risk of developing ovarian cancer, and potentially lead to therapies that better treat the disease.

In addition to Berchuck and Schildkraut, Duke study authors include Rachel Palmieri Weber of the Department of Community and Family Medicine and Edwin Iversen of the Department of Statistical Science and Cancer Prevention, Detection and Control Research Program.

(AP) ? Hundreds of pages of police reports in the investigation of the Tucson shooting rampage that wounded former Rep. Gabrielle Giffords are being released Wednesday, marking the public's first glimpse into documents that authorities have kept private since the attack more than two years ago.

The Pima County sheriff's department will release an estimated 2,700 pages of records from the January 2011 shooting at a meet-and-greet event outside a grocery store that killed six people and wounded Giffords and 11 others. The documents include transcribed interviews with witnesses, various police reports and other records, and could provide new insight into how the shooting occurred.

News organizations seeking the records were repeatedly denied the documents in the months after the shooting and the arrest of 24-year-old Jared Lee Loughner, who was sentenced in November to seven consecutive life sentences, plus 140 years, after he pleaded guilty to 19 federal charges.

U.S. District Judge Larry Burns had prevented the sheriff's department from releasing the records in response to a request from The Washington Post, ruling in March 2011 that Loughner's right to a fair trial outweighed whatever disclosures might be authorized under state law.

Last month, Burns cleared the way for the release of the records after Star Publishing Company, which publishes the Arizona Daily Star in Tucson, had sought their release. The judge said Loughner's fair-trial rights are no longer on the line now that his criminal case has resolved.

Loughner's guilty plea enabled him to avoid the death sentence. He is serving his sentence at a federal prison medical facility in Springfield, Mo., where he was diagnosed with schizophrenia and forcibly given psychotropic drug treatments.

Arizona's chief federal judge and a 9-year-old girl were among those killed in the rampage. Giffords was left partially blind, with a paralyzed right arm and brain injury. She resigned from Congress last year and has since started, along with her husband, a gun control advocacy group.

The Star said it wanted the records because they contain information about how a mass shooting occurs, including how long it took Loughner to fire gunshots ? an issue raised by some advocates in the debate over high-capacity pistol magazines.

The Tucson newspaper argued that the records are critical in the national debate over whether such shootings could be prevented by armed resistance, whether a mass shooting occurs too quickly to be stopped and whether people with mental illnesses should be prohibited from getting guns.

Phoenix Newspapers Inc., which publishes The Arizona Republic, and KPNX-TV had joined Star Publishing in the latest effort to get the records released.

Engineers enable 'bulk' silicon to emit visible light for the first time

Mar. 27, 2013 ? Electronic computing speeds are brushing up against limits imposed by the laws of physics. Photonic computing, where photons replace comparatively slow electrons in representing information, could surpass those limitations, but the components of such computers require semiconductors that can emit light.

Now, research from the University of Pennsylvania has enabled "bulk" silicon to emit broad-spectrum, visible light for the first time, opening the possibility of using the element in devices that have both electronic and photonic components.

The research was conducted by associate professor Ritesh Agarwal, postdoctoral fellow Chang-Hee Cho and graduate students Carlos O. Aspetti and Joohee Park, all of the Department of Materials Science and Engineering in Penn's School of Engineering and Applied Science.

Their work was published in Nature Photonics.

Certain semiconductors, when imparted with energy, in turn emit light; they directly produce photons, instead of producing heat. This phenomenon is commonplace and used in light-emitting diodes, or LEDs, which are ubiquitous in traffic signals, new types of light bulbs, computer displays and other electronic and optoelectronic devices. Getting the desired photonic properties often means finding the right semiconducting material. Agarwal's group produced the first ever all-optical switch out of cadmium sulfide nanowires, for example.

Semiconducting materials -- especially silicon -- form the backbone of modern electronics and computing, but, unfortunately, silicon is an especially poor emitter of light. It belongs to a group of semiconducting materials, which turns added energy into heat. This makes integrating electronic and photonic circuits a challenge; materials with desirable photonic properties, such as cadmium sulfide, tend to have poor electrical properties and vice versa and are not compatible with silicon-based electronic devices.

"The problem is that electronic devices are made of silicon and photonic devices are typically not," Agarwal said. "Silicon doesn't emit light and the materials that do aren't necessarily the best materials for making electronic devices."

With silicon entrenched as the material of choice for the electronics industry, augmenting its optical properties so it could be integrated into photonic circuitry would make consumer-level applications of the technology more feasible.

"People have tried to solve this problem by doping silicon with other materials, but the light emission is then in the very long wavelength range, so it's not visible and not very efficient and can degrade its electronic properties," Agarwal said. "Another approach is to make silicon devices that are very small, five nanometers in diameter or less. At that size you have quantum confinement effects, which allows the device to emit light, but making electrical connections at that scale isn't currently feasible, and the electrical conductivity would be very low."

To get elemental, "bulk" silicon to emit light, Agarwal's team drew upon previous research they had conducted on plasmonic cavities. In that earlier work, the researchers wrapped a cadmium sulfide nanowire first in a layer of silicon dioxide, essentially glass, and then in a layer of silver. The silver coating supports what are known as surface plasmons, waves that are a combination of oscillating metal electrons and of light. These surface plasmons are highly confined to the surface where the silicon dioxide and silver layers meet. For certain nanowire sizes, the silver coating creates pockets of resonance and hence highly confined electromagnetic fields -- in other words, light -- within the nanostructure.

Normally, after excitation the semiconductor must first "cool down," releasing energy as heat, before "jumping" back to the ground state and finally releasing the remaining energy as light. The Penn team's semiconductor nanowires coupled with plasmonic nanocavities, however, can jump directly from a high-energy excited state to the ground state, all but eliminating the heat-releasing cool-down period. This ultra-fast emission time opens the possibility of producing light from semiconductors such as silicon that might otherwise only produce heat.

"If we can make the carriers recombine immediately," Agarwal said, "then we can produce light in silicon."

In their latest work, the group wrapped pure silicon nanowires in a similar fashion, first with a coating of glass and then one of silver. In this case, however, the silver did not wrap completely around the wire as the researchers first mounted the glass-coated silicon on a sperate pane of glass. Tucking under the curve of the wire but unable to go between it and the glass substrate, the silver coating took on the shape of the greek letter omega -- ? -- while still acting as a plasmonic cavity.

Critically, the transparent bottom of the omega allowed the researchers to impart energy to the semiconductor with a laser and then examine the light silicon emitted.

Even though the silicon nanowire is excited at a single energy level, which corresponds to the wavelength of the blue laser, it produces white light that spans the visible spectrum. This translates into a broad bandwidth for possible operation in a photonic or optoelectronic device. In the future, it should also be possible to excite these silicon nanowires electrically.

"If you can make the silicon emit light itself, you don't have to have an external light source on the chip," Agarwal said. "We could excite the silicon electrically and get the same effect, and we can make it work with wires from 20 to 100 nanometers in diameter, so it's very compatible in terms of length scale with current electronics."

The research was supported by the U.S. Army Research Office and the National Institutes of Health.

Instagram ? The King of All Photo Apps! - Computer Tech Support

Living in the 21st century provides many different ways for people to both stay in touch with friends and family, as well as meet new and exciting people from all over the world. What started with message boards and email has branched out into a whole world of online interconnectedness.

With the increase in capabilities that current technology offers, contact has evolved from simple text communications to the allowance of more advanced types of expression. Many different software programs have been created, both free and paid, that allow us to spice up our communications in a myriad of different ways. Users can personalize messages with different colors, fonts and emoticons, all of which provide an outlet for creativity and a way for us to put a little of ourselves into the messages we send.

One of the most significant types of medium that has benefited from the increased transfer speeds of broadband is photos. Virtually every type of online social interaction has the capacity for users to exchange pictures with each other, in one way or another. This fact has taken things to a whole new level in terms of social networking. Now, not only can you share all of the information that you find important, but also the accompanying images that are equally as important. This trend has become so popular that one of the most exciting new social networking services is centered completely around the posting and sharing of images. I am, of course, referring to Instagram.

Introducing Instagram

Initially developed and released in 2010, Instagram has grown at a phenomenal pace to a current user base that tops 100 million. Instagram differs slightly from many of the other social networking platforms, such as Facebook and MySpace, in that it was introduced to run completely over mobile computing platforms, as opposed to being primarily internet based. While the capability for online profiles was introduced in 2012, Instagram remains primarily a tool for smartphone and tablet users.

Basic participation in Instagram?s services include the posting of photos to an account, after which they can be made available for viewing to user-defined persons or groups. Photos can also be shared across other social networking platforms by linking the Instagram account to the accounts held in the other services. Members can also elect to ?follow? another person?s account, allowing them to stay current on all of the content posted by that member instantly.

Images posted to Instagram can be manipulated through the use of one of the many filters that are offered. These filters apply different color enhancements to the posted image, allowing for an even greater degree of customization. With nearly 20 different available filters to use, the opportunity to show your content in the exact way you want it to appear is virtually limitless.

Acquiring an Account

Upon visiting Instagram?s homepage, located at www.instagram.com, you will be presented with the option to either download the app from the App Store (for iPhone users) or Google Play (for Android users). Once you have finished downloading, installing and opening the app on your mobile device, you will tap the Sign Up button to proceed.

Once the signup process has been completed you have several different destinations available to go to in order to customize your profile and begin posting content. These include a Profile tab, which allows you to view and update your Instagram account and a Camera tab, which allows you to take photos or upload images from your device?s internal storage.

Instagram has gone a long way towards offering a social networking solution for those whose primary method of computing and communication is done through a mobile device. In addition, their clear goal towards developing a service based primarily on images has been instrumental in reinforcing that old adage of a picture being worth a thousand words.

U.S. flies stealth bombers over South Korea in warning to North

SEOUL (Reuters) - The United States flew two nuclear-capable stealth bombers on practice runs over South Korea on Thursday, in a rare show of force following a series of North Korean threats that the Pentagon said have set Pyongyang on a dangerous path. The drill by the two B-2 Spirit bombers - flying all the way from the United States and back - appeared to be the first exercise of its kind and showed America's ability to conduct long-range, precision strikes "quickly and at will," the U.S. military said.

Mortar kills 15 at Damascus University, Syria says

BEIRUT/ISTANBUL (Reuters) - Fifteen Syrian students were killed when rebel mortar shells hit a Damascus University canteen on Thursday, state-run news agency SANA said, as attacks intensified in the center of the capital. The Syrian Observatory for Human Rights, an opposition monitoring group, said a mortar killed 13 people at the university, without saying who fired the bombs.

Attempt to end Italy crisis stalls, president mulls next move

ROME (Reuters) - Center-left leader Pier Luigi Bersani has failed in his attempt to find a way out of Italy's political deadlock and President Giorgio Napolitano will now seek another solution, the president's palace said on Thursday. Bersani reported back to Napolitano on Thursday night after being given a mandate almost a week ago to see if he could muster enough support to form a government after the inconclusive election in February.

U.S. debates how severely to penalize Russia in human rights spat

WASHINGTON (Reuters) - In a controversy underscoring continued stresses in U.S.-Russia relations, Obama administration officials are debating how many Russian officials to ban from the United States under a new law meant to penalize Moscow for alleged human rights abuses. The debate's outcome, expected in about two weeks, is likely to illustrate how President Barack Obama will handle what critics say is a crackdown on dissent in Russia and set the tone for Washington-Moscow relations in the president's second term.

Kenyatta apologizes for judges gaffe before Kenya poll ruling

NAIROBI (Reuters) - Kenya's president-elect, whose victory is being challenged in the Supreme Court, apologized on Thursday for seeming to dismiss the judges as "some six people" who will "decide something or other". Uhuru Kenyatta, who also faces trial at the International Criminal Court for crimes against humanity over post-election violence five years ago, made the remarks - which went viral on social media - while consulting allies at a resort.

Analysis: Gay marriage rights may carry bigger U.S. tax burden for some

WASHINGTON (Reuters) - If the U.S. Supreme Court strikes down a federal law defining marriage as between a man and woman, the newfound rights for gay married couples may bear something not so welcome - a bigger tax burden. That's because with equality, gay couples will face the same tax woes of many heterosexual couples with similar incomes, including the tax hit known in America as the marriage penalty.

Spy who foiled jet bomb plot to be Britain's intelligence chief

LONDON (Reuters) - A British counterspy who helped to thwart an al Qaeda plot to blow up planes with explosives hidden in soft drink bottles and led the response to the 2005 London transport bombings will be the new head of Britain's domestic intelligence agency, the U.K. government said on Thursday. Andrew Parker has three decades' experience at the Security Service, known as MI5, countering Islamist militants, violent Irish republicans and organized criminals. He has been deputy chief since 2007, and once served as a British security liaison in the United States.

Irish PM's party wins by-election, junior partner suffers

ASHBOURNE, Ireland (Reuters) - Irish Prime Minister Enda Kenny's Fine Gael party held its seat in a by-election on Thursday, but its junior coalition partner Labor was beaten into fifth place in a humiliating defeat. Labour went into government for the first time since the late 1990s two years ago on a promise to end the previous administration's Laboradherence to "Frankfurt's Way", an austerity plan the party said was dictated by the European Central Bank.

Beleaguered Hollande to reach out to nation on TV

PARIS (Reuters) - With his approval ratings and most of his economic pledges in tatters, French President Francois Hollande will try to convince a disillusioned nation on television on Thursday to keep faith in him to restore the economy to health. Hollande will be grilled in a 45-minute interview on France 2 television, his first such appearance in several months, in a studio whose backdrop and lighting have been prepared by his media team to create a somber mood.

NATO approves Breedlove's nomination as top commander

BRUSSELS (Reuters) - NATO said on Thursday it had approved the nomination of U.S. Air Force General Philip Breedlove to be the Western alliance's top military commander. Breedlove, whose nomination was endorsed by ambassadors from the 28 NATO allies, will succeed Admiral James Stavridis as NATO's Supreme Allied Commander Europe. His appointment requires U.S. Senate confirmation.

Pope washes feet of young detainees in ritual

In this photo provided by the Vatican newspaper L'Osservatore Romano, Pope Francis washes the foot of an inmate at the juvenile detention center of Casal del Marmo, Rome, Thursday, March 28, 2013. Francis washed the feet of a dozen inmates at a juvenile detention center in a Holy Thursday ritual that he celebrated for years as archbishop and is continuing now that he is pope. Two of the 12 were young women, an unusual choice given that the rite re-enacts Jesus' washing of the feet of his male disciples. The Mass was held in the Casal del Marmo facility in Rome, where 46 young men and women currently are detained. Many of them are Gypsies or North African migrants, and the Vatican said the 12 selected for the rite weren't necessarily Catholic. (AP Photo/L'Osservatore Romano, ho)

(AP) ? Pope Francis washed and kissed the feet of a dozen inmates, including two young women, at a juvenile detention center in a surprising departure from church rules that restrict the Holy Thursday ritual to men.

The Mass was held in the Casal del Marmo facility in Rome, where 46 young men and women currently are detained. Many of them are Gypsies or North African migrants, and the 12 selected for the foot-washing rite reportedly included Orthodox and Muslim detainees.

Because the inmates were mostly minors ? the facility houses inmates aged 14-to-21 ? the Vatican and Italian Justice Ministry limited media access inside. But Vatican Radio carried the Mass live, and in his homily Francis told the detainees that Jesus washed the feet of his disciples on the eve of his crucifixion in a gesture of love and service.

"This is a symbol, it is a sign ? washing your feet means I am at your service," Francis told the youngsters. "Help one another. This is what Jesus teaches us. This is what I do. And I do it with my heart. I do this with my heart because it is my duty, as a priest and bishop I must be at your service."

Later, the Vatican released a limited video of the ritual, showing Francis washing black feet, white feet, male feet, female feet and even a foot with tattoos. Kneeling on the stone floor as the 12 youngsters sat above him, the 76-year-old Francis poured water from a silver chalice over each foot, dried it with a simple cotton towel and then bent over to kiss each one.

Previous popes carried out the foot-washing ritual on Holy Thursday in Rome's grand St. John Lateran basilica. The 12 people chosen for the ritual were always priests to represent the 12 apostles whose feet Christ washed during the Last Supper before his crucifixion.

As archbishop of Buenos Aires, the former Cardinal Jorge Mario Bergoglio would celebrate the ritual foot-washing in jails, hospitals or hospices ? part of his ministry to the poorest and most marginalized of society. He would often involve women: photographs from his days in Buenos Aires show him washing the feet of a woman holding her newborn child in her arms.

That Francis would include women in his inaugural Holy Thursday Mass as pope, however, was remarkable given current liturgical rules restrict the ritual to men.

Canon lawyer Edward Peters, who is an adviser to the Holy See's top court, noted in a blog that the Congregation for Divine Worship in 1988 sent a letter to bishops making clear that "The washing of the feet of chosen men ... represents the service and charity of Christ who came 'not to be served, but to serve.'"

Peters noted that bishops over the years have successfully petitioned Rome for an exemption to allow women to participate, but that the law on the issue is clear.

"By disregarding his own law in this matter, Francis violates, of course, no divine directive," Peters wrote Thursday. "What he does do, I fear, is set a questionable example," particularly as it regards adherence to liturgical rules.

The Vatican spokesman, the Rev. Federico Lombardi, said he didn't want to enter into a canonical dispute over the matter. He said in a "grand solemn celebration" of the rite, it would make sense to only involve men because during the Last Supper, Christ washed the feet of the 12 apostles, all of whom were male.

"Here, the rite was for a small, unique community made up also of women," Lombardi said in an email to The Associated Press. "It was a specific situation in which excluding the girls would have been inopportune in light of the simple aim of communicating a message of love to all in a group that certainly didn't include refined experts in liturgical rules."

Others on the more liberal side of the liturgical spectrum welcomed the novel example Francis set.

"The pope's washing the feet of women is hugely significant because including women in this part of the Holy Thursday Mass has been frowned on ? and even banned ? in some dioceses," said the Rev. James Martin, a Jesuit priest and author of "The Jesuit Guide."

"It shows the all-embracing love of Christ, who ministered to all he met: man or woman, slave or free, Jew or Gentile," he said.

After the Mass, Francis greeted each of the inmates and gave each one an Easter egg. In exchange, he was given a wooden cross and kneeler that the inmates made in their workshop.

"Don't lose hope," Francis said. "Understand? With hope you can always go on."

One of the inmates then asked him why he had come to visit them. Francis said it was to "help me to be humble, as a bishop should be." He said he wanted to come "from my heart. Things from the heart don't have an explanation."

Italian Justice Minister Paola Severino, who has made easing Italy's woefully overcrowded prisons a priority, also attended the Mass.

Messier 77 is a galaxy in the constellation of Cetus, some 45 million light-years away from us. Also known as NGC 1068, it is one of the most famous and well-studied galaxies. It is a real star among galaxies, with more papers written about it than many other galaxies put together!

Despite its current fame and striking swirling appearance, the galaxy has been a victim of mistaken identity a couple of times; when it was initially discovered in 1780, the distinction between gas clouds and galaxies was not known, causing finder Pierre Mechain to miss its true nature and label it as a nebula. It was misclassified again when it was subsequently listed in the Messier Catalogue as a star cluster.

Now, however, it is firmly categorised as a barred spiral galaxy, with loosely wound arms and a relatively small central bulge. It is the closest and brightest example of a particular class of galaxies known as Seyfert galaxies -- galaxies that are full of hot, highly ionised gas that glows brightly, emitting intense radiation.

Strong radiation like this is known to come from the heart of Messier 77 -- caused by a very active black hole that is around 15 million times the mass of our Sun. Material is dragged towards this black hole and circles around it, heating up and glowing strongly. This region of a galaxy alone, although comparatively small, can be tens of thousands of times brighter than a typical galaxy.

Although no competition for the intense centre, Messier 77's spiral arms are also very bright regions. Dotted along each arm are knotty red clumps -- a signal that new stars are forming. These baby stars shine strongly, ionising nearby gas which then glows a deep red colour as seen in the image above. The dust lanes stretching across this image appear as a rusty, brown-red colour due to a phenomenon known as reddening; the dust absorbs more blue light than red light, enhancing its apparent redness.

A version of this image won second place in the Hubble's Hidden Treasures Image Processing Competition, entered by contestant Andre van der Hoeven [1].
