Leap Second Granted Extra Time

From Nature magazine

Clocks around the world are routinely adjusted to keep them ticking in synchrony with the rising and setting of the Sun ? but is that effort just a waste of time? That was the issue under debate this week by the World Radiocommunication Assembly of the International Telecommunication Union in Geneva, Switzerland.

Delegates from about 150 countries discussed whether to stop adding a second ? called a leap second ? to calendars every year or so, a practice that keeps atomic clocks in step with Earth's rotation and the position of the Sun in the sky. But participants reached a state of confusion, rather than consensus, so the decision about the leap-second's fate has been deferred to 2015.

Since 1972, international time zones have been defined against Coordinated Universal Time (UTC), which is based on signals averaged from around 400 atomic clocks. Leap seconds are added in at a rate of about one minute every 60-90 years. But nations disagree about whether the second is actually needed

Opening Thursday's debate was the US delegate, Paul Najarian, Director of Telecommunications and Standards at the United Nations' International Telecommunication Union (America). Najarian pointed out some of the technical headaches that leap seconds cause: they cannot be preprogrammed into software, for example, because they are typically announced only six months in advance by the International Earth Rotation and Reference Systems Service in Frankfurt, Germany. Introducing them manually raises the risk of inconsistencies between computer systems, which can cause them to crash. To avoid the safety hazards associated with losing crucial time-keeping signals, most satellite navigation systems already maintain their own internal clocks, and they don't use the leap second.

But the British delegation leapt to the leap-second's defence. "The United Kingdom is strongly opposed to coming up with a new conception of time, without good reason," says Peter Whibberley, a physicist at the National Physical Laboratory in Teddington.

Both sides had a handful of backers from other nations, but many of the delegates ? a mixture of government represenatives and technical experts ? were simply not prepared for the proposal, and said they needed more information before deciding.

Obama isn't the first president to serenade public (AP)

Is it too much to ask our presidents to uphold the Constitution, command the armed forces, execute the nation's laws ? AND provide us with a little musical interlude?

The question comes to mind in the wake of Barack Obama's appearance at the Apollo Theater, when the leader of the free world took a moment to channel the Rev. Al Green, singing a bar from "Let's Stay Together." The crowd (and admirers on the Internet) went nuts, reacting in a way they rarely do to, say, a veto message or a Thanksgiving Proclamation.

Obama, of course, is not the first president to show his tuneful side to the public. Through the years, commanders-in-chief have turned musicians-in-chief, with varying results.

Among them:

_RICHARD NIXON. He was no Billy Joel. And yet twice in 1974, in the last months of his doomed administration, the President Who Was Not a Crook became the President Who Was the Piano Man. He played "God Bless America" at the Grand Ole Opry, and the same tune when he accompanied singer Pearl Bailey in the East Room of the White House. The two also conspired on "Home on the Range" and "Wild Irish Rose." "You don't play as well as I sing," Bailey joked, "but I don't sing as well as you govern." She was half right.

Nixon also appeared on TV with Jack Paar in 1963, and played a little concerto of his own devising. Nixon said this would put the kibosh on his political career: "The Republicans don't want to another piano player in the White House," he said.

_HARRY TRUMAN. Nixon was referring to "Give `em Hell Harry," a Democrat who could never pass a piano without sitting down to play a few bars. In 1952, Truman conducted a nationally televised tour of the newly renovated White House and played a bit on the 1938 Steinway. The building had been condemned when a leg of piano played by his daughter Margaret, a singer whose talent was of some dispute, crashed through the floor of the decrepit mansion.

Truman also played for Joseph Stalin and Winston Churchill at the Potsdam Conference, neither shortening nor lengthening World War II appreciably. The man did love the piano: "My choice early in life was either to be a piano-player in a whorehouse or a politician," he once said. "And to tell the truth, there's hardly any difference."

_THOMAS JEFFERSON. He played the violin, and not just to meet women (though that is how he came to know his harpsichord-playing wife, Martha). When he wasn't writing the Declaration of Independence or rewriting the Bible or inventing a four-sided music stand for string quartets, he made music. He played the cello and clavichord, but the violin was his instrument, and he was a ringer for several orchestras. Though often in need of money, he always refused payment.

_BILL CLINTON. William Jefferson Clinton, not yet president, took a giant step in that direction in June 1992 when he showed up with a saxophone and wraparound sunglasses to play "Heartbreak Hotel" on "The Arsenio Hall Show." "It's nice to see a Democrat blow something besides the election," quipped the host.

After he won the presidency, Clinton played with E Street Band saxophonist Clarence Clemons at an inaugural ball. He also took a moment from an East European tour in 1994 to climb the stage of Prague's Reduta Jazz Club and play "My Funny Valentine" and "Summertime." At one point he invited Czech leader Vaclav Havel to join him; this would be remembered in political and musical history as the Two Presidents Gig.

_Many other chief executives performed, though not necessarily in public. John Quincy Adams played the flute, Chester Arthur the banjo, Woodrow Wilson the violin. Franklin Roosevelt liked to sing. And John Tyler ? of "Tippecanoe and Tyler, too" fame ? organized his 15 children in a White House minstrel band. Historian Elise Kirk says this probably included banjo, bones, drums and guitar. Plus a country fiddle.

Mercifully, no videos exist.

Lawmakers flip on piracy bills protested on Web (Reuters)

(Reuters) ? Some members of Congress switched sides to oppose antipiracy legislation as protests blanketed the Internet on Wednesday, turning Wikipedia dark and putting black slashes on Google and other sites as if they had been censored.

Content providers who favor the anti-piracy measures, such as Hollywood and the music industry, were scrambling to win back public opinion and official support.

Wikipedia, the world's free online encyclopedia, shut down for a day. Google and others used the black censorship bars to draw attention to what had until recently been an obscure and technical legislative proposal to curb access to overseas websites that traffic in stolen content or counterfeit goods.

Many of the sites participating in the blackout urged their users to contact their legislators on the issue, a plea that brought quick results.

Several sponsors of the legislation, including Senators Roy Blunt, Chuck Grassley, Orrin Hatch and John Boozman and Marco Rubio, said they were withdrawing their support. Some blamed Senate Majority Leader Harry Reid for rushing the Senate version of the bill.

Meanwhile, friends of the bills stepped up their efforts.

Creative America, a studio- and union-supported group that fights piracy, launched a television advertising campaign that it said would air in the districts of key legislators. In Times Square, it turned on a digital pro-SOPA and PIPA billboard for the day - in space provided by News Corp, which owns Fox Studios.

The group also said it is sending a team of 20 organizers to big events around the country, including the upcoming Sundance Film Festival, to try to get voters to see the situation their way.

The legislation, known as PIPA in the Senate and SOPA in the House of Representatives, has been a priority for entertainment companies, publishers, pharmaceutical companies and other industry groups who say it is critical to curbing online piracy, which they believe costs them billions of dollars a year.

But Internet players argue the bills would undermine innovation and free speech rights and would compromise the functioning of the Internet.

In switching their positions, Blunt called the legislation "deeply flawed" while Rubio and Boozman cited "unintended consequences" that could stem from the proposed law. All said they still supported taking action against online piracy.

Other lawmakers, such as Senator Kristen Gillibrand, said they supported changes to the legislation.

The blackout affected thousands of sites and served as the culmination of several efforts online to fight the legislation. In recent days, for example, many Twittter users placed black "Stop SOPA" bands on the bottom of their profile pictures.

Even sites that didn't black out their sites, which would have cost them a day's worth of advertising revenue and angered some consumers, made their opposition to the bills plain.

"We can't let poorly thought out laws get in the way of the Internet's development," Facebook chief executive Mark Zuckerberg said in a statement.

Zynga issued a blog post complaining that "the overly broad provisions we've seen in the pending SOPA and PIPA bills could be used to target legitimate U.S. sites and chill innovation at a time when it is needed most."

While the Facebook and Zynga sites functioned as normal, others looked jarringly different.

Wikipedia mounted a 24-hour protest starting at midnight by converting their English page to a shadowy black background and warning readers that "the U.S. Congress is considering legislation that could fatally damage the free and open Internet."

It included a link to help Internet users contact their representatives.

Craigslist, the free Internet classifieds site, also went black in protest, while Google's home search page included a black bar slapped over its logo and asked readers: "Tell Congress: Please don't censor the web!"

Smaller sites, such as Reddit.com and BoingBoing.net, were also dark, while icanhascheezburger.com placed a banner over its site alerting users to the situation and inviting them to click on a link for more information.

"It's a way of engaging the public in something that had been a very much behind closed doors, kind of business as usual in Washington thing," said Bill Allison, editorial director at the Sunlight Foundation, a lobbying watchdog group. "It's a way to get the public aware and alerted to it, and somewhat on their side."

A lunchtime protest in San Francisco drew about 100 protesters, including Craigslist founder Craig Newmark and rapper M.C. Hammer, who called the proposed legislation "barbaric."

But content providers said the protests were long on hype and short on substance, and that reaching voters one-on-one and in person would prove more effective. "We see this as a long battle," said Mike Nugent, executive director of Creative America. He has been sending outreach staff to events like local festivals and movie screenings to get them to call their legislators and enlist their support.

MOMENTUM COOLS

The bills were seemingly on track for approval by Congress, but sentiment has shifted in recent weeks and an implicit veto threat from the White House over the weekend cast doubt on whether the legislation would pass.

Republican Representative Tom Price, head of the House Republican Policy Committee, said in a hallway interview, "I don't think it is going anywhere."

"There is real confusion about it, number one, but number two, there are real concerns about whether or not it would shut down the ability of entrepreneurs, new businesses and the like to utilize the Internet for their purposes," Price said.

When asked about the anti-piracy legislation at a news conference on Wednesday, House Speaker John Boehner said lawmakers will continue to try to find support for it, but that it's not there now.

"It's pretty clear to many of us that there is a lack of consensus at this point," Boehner said.

The protest drew some criticism ahead of its launch.

"This publicity stunt does a disservice to its users by promoting fear instead of facts," Lamar Smith, Republican chairman of the House Judiciary Committee and a sponsor of SOPA, said in a statement on Tuesday. "Perhaps during the blackout, Internet users can look elsewhere for an accurate definition of online piracy."

Former Senator Chris Dodd, who now chairs the Motion Picture Association of America, labeled the blackout a "gimmick" and called for its supporters to "stop the hyperbole and PR stunts and engage in meaningful efforts to combat piracy."

The blackout harkens back to some similar movements on the Internet in recent years, particularly a 2007 protest over online radio royalties. Then, services like Pandora turned off their music for a day. Two years later, the music services and record labels reached an agreement over the payments.

US obesity epidemic shows no hint of shrinking (AP)

CHICAGO ? America's obesity epidemic is proving to be as stubborn as those maddening love handles, and shows no sign of reversing course.

More than one-third of adults and almost 17 percent of children were obese in 2009-2010, echoing results since 2003, the Centers for Disease Control and Prevention reported Tuesday.

"It's good that we didn't see increases. On the other hand, we didn't see any decreases in any group," said CDC researcher Cynthia Ogden.

Early in the decade, slight increases were seen among white, black and Hispanic men, and among Hispanic and black women. These changes may be leveling off, but the authors said they "found no indication that the prevalence of obesity is declining in any group."

In 2009-2010, more than 78 million adults and almost 13 million children aged 2-19 were obese, the CDC researchers reported.

Those numbers are staggering, and while they haven't increased in recent years, "we're plateauing at an unacceptably high prevalence rate," said Dr. David Ludwig, director of an obesity prevention center at Children's Hospital Boston. He was not involved in the reports.

The CDC reports summarize results of national health surveys in children and adults, which are conducted every two years. The nationally representative surveys include in-person weight and height measurements. The 2009-2010 reports involved nearly 6,000 adults and about 4,000 children, from infancy through age 19.

The results were released online in the Journal of the American Medical Association.

Dr. Elbert Huang, an associate professor of medicine at the University of Chicago who studies health care policy issues, said his research shows that even if obesity rates continue to remain stable, there will be dramatic increases down the road in diabetes and in costs linked with that disease. That's because Type 2 diabetes, among many diseases linked with obesity, becomes more prevalent as people age.

The latest reports ? one on children and the other on adults ? focused on obesity, meaning a body-mass index of at least 30. But the numbers of adults and children who were overweight, with a BMI of between 25 and 29, also remained high.

Overall, 33 percent of adults were overweight but not obese, versus about 15 percent of children and teens.

Rates of overweight or obese adults and children were generally higher in blacks and Hispanics than in whites.

The government says a healthy weight is a BMI of between 18 and 25. The index is a ratio of height to weight.
