Today in History

Today is Sunday, May 19, the 139th day of 2013. There are 226 days left in the year.

Today's Highlights in History:

On May 19, 1943, in his second wartime address to the U.S. Congress, British Prime Minister Winston Churchill pledged his country's full support in the fight against Japan. That same day, top U.S. and British officials meeting in Washington reached agreement on May 1, 1944 as the date for the D-Day invasion of France (the operation ended up being launched more than a month later).

On this date:

In 1536, Anne Boleyn, the second wife of England's King Henry VIII, was beheaded after being convicted of adultery.

In 1780, a mysterious darkness enveloped much of New England and part of Canada in the early afternoon.

In 1909, the Ballets Russes (Russian Ballets), under the direction of Sergei Diaghilev, debuted in Paris.

In 1913, California Gov. Hiram Johnson signed the Webb-Hartley Law prohibiting "aliens ineligible to citizenship" from owning farm land, a measure targeting Asian immigrants, particularly Japanese.

In 1921, Congress passed, and President Warren G. Harding signed, the Emergency Quota Act, which established national quotas for immigrants.

In 1935, T.E. Lawrence, also known as "Lawrence of Arabia," died in Dorset, England, six days after being injured in a motorcycle crash.

In 1962, actress Marilyn Monroe sang "Happy Birthday to You" to President John F. Kennedy during a Democratic fundraiser at New York's Madison Square Garden.

In 1964, the State Department disclosed that 40 hidden microphones had been found in the U.S. embassy in Moscow.

In 1973, Secretariat won the Preakness Stakes, the second of his Triple Crown victories.

In 1981, five British soldiers were killed by an Irish Republican Army landmine in County Armagh, Northern Ireland.

In 1993, the Clinton White House set off a political storm by abruptly firing the entire staff of its travel office; five of the seven staffers were later reinstated and assigned to other duties.

In 1994, former first lady Jacqueline Kennedy Onassis died in New York at age 64.

Ten years ago: WorldCom Inc. agreed to pay investors $500 million to settle civil fraud charges. The Supreme Court dealt a defeat to the drug industry, ruling 6-3 that a state (in this case, Maine) may try to force companies to lower prices on prescription medications for the poor and uninsured. A Palestinian woman blew herself up during a security check outside a mall, killing three Israelis in the fifth suicide bombing in 48 hours.

Five years ago: Chinese stood still and sirens wailed to mourn the country's nearly 70,000 earthquake victims. Democrat Barack Obama picked up the endorsement of Sen. Robert Byrd of West Virginia, less than a week after Hillary Rodham Clinton overwhelmingly won the state's primary. Jon Lester of the Boston Red Sox shut down Kansas City 7-0 for the first no-hitter of the season.

One year ago: President Barack Obama and other G-8 leaders held economic talks at Camp David, where they declared that their governments needed to both spark growth and cut debt. Chen Guangcheng (chehn gwahng-chung), a blind Chinese legal activist, was hurriedly taken from a hospital and put on a plane for the United States, closing a nearly monthlong diplomatic tussle that had tested U.S.-China relations. I'll Have Another overtook Bodemeister down the stretch to win the Preakness, two weeks after claiming the Kentucky Derby. (However, a tendon injury forced I'll Have Another into retirement on the eve of the Belmont Stakes.)

Today's Birthdays: PBS newscaster Jim Lehrer is 79. TV personality David Hartman is 78. Actor James Fox is 74. Actress Nancy Kwan is 74. Actor Peter Mayhew is 69. Rock singer-composer Pete Townshend (The Who) is 68. Concert pianist David Helfgott is 66. Rock singer-musician Dusty Hill (ZZ Top) is 64. Singer-actress Grace Jones is 61.

Ben Bernanke Optimistic About Future Innovation In Commencement Address


WASHINGTON, May 18 (Reuters) - U.S. Federal Reserve Chairman Ben Bernanke painted an upbeat picture on Saturday for the potential of innovation to lift living standards, delivering a sweeping look at the last 100 years that included memories of his 1963 South Carolina home.
Bernanke made no reference to monetary policy or the immediate outlook for the U.S. economy in prepared remarks to graduates of Bard College at Simon's Rock, Massachusetts.
But the die-hard baseball fan did manage to work in a reference to one of the sport's greats.
"Is it true, then, as baseball player Yogi Berra said, that the future ain't what it used to be?," the chairman said, noting the existence of serious skepticism that leaps in computers and other information technology would yield the same dramatic boost to growth and living standards as previous episodes of industrial revolution.
"Nobody really knows; as Berra also astutely observed, it's tough to make predictions, especially about the future. But there are some good arguments on the other side of this debate."
Bernanke delivers testimony on the U.S. economy on Wednesday before the congressional Joint Economic Committee.
His words will be parsed for any hint that he favors tapering Fed bond purchases, currently running at an $85 billion monthly pace. But recent U.S. economic data has been mixed, and economists polled by Reuters continue to expect the bond buying to continue until later this year, if not into early 2014.
Bernanke did not tip his hand during his comments to graduates, but he did offer some rare insights into his childhood home in Dillon, South Carolina to illustrate how life has not changed all that much in the last 50 years.
"We had a dishwasher, a washing machine, and a dryer. My family owned a comfortable car with air conditioning and a radio, and the experience of commercial flight was much like today but without the long security lines," he recalled.
There was no internet, but there was a color television "although, I must acknowledge, the colors were garish and there were many fewer channels to choose from."
After pointing out that the so-called IT revolution had not been as transformative as all that, Bernanke then went on to outline several areas where technology may only have scratched the surface in exploiting the potential for change.
He argued that IT and biotechnology have tremendous scope to improve healthcare - which absorbs a considerable amount of U.S. household income and where costs are projected to rise - as well as the potential for the development of cleaner energy.
"As trade and globalization increase the size of the potential market for new products, the possible economic rewards for being first with an innovative product or process are growing rapidly," he said. "In short, both humanity's capacity to innovate and the incentives to innovate are greater today than at any other time in history." (Reporting by Alister Bull; Editing by Tim Dobbyn)

All Critics (117) | Top Critics (31) | Fresh (111) | Rotten (7) | DVD (1)

The human brain is a marvellously suggestible organ.

[A] strange, frustrating, occasionally fascinating doc ...

"Room 237" evolves from an ode to movie love at its most delirious to a wry examination of the crackpot mind at work.

There's enough real evidence supporting the theory that Kubrick was a genius, and that's pretty entertaining all by itself.

It's about the human need for stuff to make sense - especially overpowering emotional experiences - and the tendency for some people to take that sense-making to extremes.

The results can range from enlightening - Kubrick did like to mess with things - to embarrassing. But it's never dull. "Room 237" shines.

It has the same entertainment value as listening to a late-night radio host indulge his listeners on Roswell, Area 51 and 9/11. Everything sounds completely crackers, until it all makes crazy sense.

What emerges from Room 237 is not a denigration of conspiracies, but a kind of celebration of our ability to create patterns where (perhaps) none exist.

"Room 237" could become an essential companion piece to "The Shining" from now on. For those who see both, it will be impossible to think about one without the other.

...all about the work of criticism - finding fresh avenues of delight.

Watching it makes you feel like you're attending a really entertaining film class where your classmates confidently let their freak flags fly.

It's an essay about the human need to reject the notion of a random universe and find order and meaning in existence. These people are developing their own creation myths, with Kubrick the mastermind responsible for the Intelligent Design.

Termitic film nerds could chow down for years on the wood chips.

You know when "Room 237? starts getting really scary? When the people in the film start making sense.

Kubrick fans and movie geeks will want to check this film out as soon as possible

Kubrick fans will take 'Shining' to 'Room 237.'

The credibility of these theories ranges from faintly plausible to frankly ridiculous, but Ascher isn't interested in judging them; his movie is more about the joys of deconstruction and the special kind of obsession that movies can inspire.

Some of the interpretations seem more of a stretch than others but all are entertainingly presented by director Rodney Ascher. (The movie) serves as a testament to Stanley Kubrick's cinematic mastery.

As fascinating as it is frustrating

It is nice to see a doc that makes you smile instead of making you angry. Anyone who is a fan of Stanley Kubrick will eat this up.

Powered by a deep and abiding affection for both The Shining and Kubrick in general, Room 237 is an amuse-bouche of remix culture.

The World's Fastest Wi-Fi Puts Your Sluggish Router to Shame

For the most part, we're all happy if we can get Internet that's fast enough to stream some HD video. But faster is always better, and a new, world-record setting network developed in Germany is so blazing fast you wouldn't know what to do with it. It can deliver multiple HD films in a second.

Developed by the Karlsruhe Institute of Technology in Germany, the new 40Gbps Wi-Fi (40x faster than Google Fiber) not only managed to nail crazy speeds, but also did it over a distance of .6 miles. The catch is that it'd never work well in your house.

The jump in speed and distance is not only thanks to state-of-the-art hardware, but a higher frequency (240GHz) than your typical Wi-Fi setup uses (2.4GHz or 5 GHz). This space seems to be a sweet spot for non-interference, letting signals dash across the air pretty easily, but a frequency so high would be very very easily thwarted by the common wall. And here in the States, the FCC might have something to say about it.

The network was tested by beaming data from the top of one skyscraper to another, and chances are this kind of "invisible fiber" connection would be its biggest application, as opposed to your home Wi-Fi. Still, it could be super useful for 'net distribution in rural area's where fiber's an expensive proposition with little pay off. Now if only they could roll out this tech as fast as it can transfer data. [Karlsruhe Institute of Technology via Discovery]

North Korea fires projectile into eastern waters

SEOUL, South Korea (AP) ? South Korea says North Korea has fired a projectile into waters off its eastern coast a day after launching three short-range missiles in the same area.

The South's Defense Ministry says the firing occurred Sunday afternoon. It did not say whether it was a missile or artillery.

North Korea routinely test-launches short-range missiles.

The launches come during a period of tentative diplomacy aimed at easing tension on the Korean Peninsula. The U.S. responded to the previous day's launches by saying threats or provocations would only further deepen North Korea's international isolation, while South Korea urged the North to take responsible actions.

Earlier this year, North Korea threatened to attack South Korea and the U.S. to protest annual joint military drills and U.N. sanctions imposed after its February nuclear test.

Crazy ants vs. Fire ants: Who's winning? (+video)

Crazy ants are taking over areas once occupied by fire ants in the South. The sting of Crazy ants isn't as painful and migrate slowly. But Crazy ants multiply faster.

By Douglas Main,?LiveScience / May 18, 2013

Invasive fire ants have been a thorn in the sides of Southerners for years. But another invasive species, the so-called "crazy" ant ? that many describe as being worse ? has arrived and is displacing fire ants in several places.

Skip to next paragraph

'; } else if (google_ads.length > 1) { ad_unit += ''; } } document.getElementById("ad_unit").innerHTML += ad_unit; google_adnum += google_ads.length; return; } var google_adnum = 0; google_ad_client = "pub-6743622525202572"; google_ad_output = 'js'; google_max_num_ads = '1'; google_feedback = "on"; google_ad_type = "text"; // google_adtest = "on"; google_image_size = '230x105'; google_skip = '0'; // -->

"When you talk to folks who live in the invaded areas, they tell you they want their fire ants back," said Edward LeBrun, a researcher at the University of Texas at Austin, in a statement from the school. "Fire ants are in many ways very polite. They live in your yard. They form mounds and stay there, and they only interact with you if you step on their mound."

Crazy ants, on the other hand, "go everywhere," invading homes and nesting in walls and crawlspaces, even damaging electrical equipment by swarming inside appliances. [Image Gallery: Ants of the World]

A study published in the April issue of the journal Biological Invasions found that in areas infested with crazy ants, few to no fire ants were present. Exactly how they are able to outcompete fire ants is so far unknown. In areas with crazy ants, the researchers also found greatly diminished numbers of native ant species, according to the study.

Fire ants are known for their painful stings and have spread through the Southeast since arriving from South America in the 1930s. Crazy ants were first discovered in Houston in 2002, and they have already spread to coastal areas from Texas to Florida, according to the researchers. Although the "crazies" don't have as painful a sting as fire ants, they multiply in even greater numbers. They are also difficult to control since they don't eat the same poison baits as fire ants do, the statement noted.

Last year, the crazy ant species was identified as Nylanderia fulva, which hails from northern Argentina and southern Brazil, according to a 2012 study in PLOS ONE. It's also known as the tawny crazy ant and was previously named the Rasberry crazy ant after the exterminator Tom Rasberry, who first discovered it. The "crazy" moniker comes from the ant's quick, seemingly random movements.

Luckily, the crazy ant doesn't spread as quickly as the fire ant, advancing only 650 feet (200 meters) per year on its own, the release noted. Therefore, it's vital that people don't accidentally transport the ant, the prime method by which it has spread, according to the release.

Colonoscopy withdrawal time, polyp removal technique also examined at DDW 2013

Orlando, FL (May 18, 2013) A ground-breaking advance in colonoscopy technology signals the future of colorectal care, according to research presented today at Digestive Disease Week (DDW). Additional research focuses on optimizing the minimal withdrawal time for colonoscopies and exploring safer methods for removing polyps.

During colonoscopy, doctors use a device called a colonoscope to examine the colon. This screening test for colorectal cancer allows a doctor to look for precancerous polyps called adenomas in the colon and rectum. A study featuring a new colonoscope that allows doctors to see more of the colon shows promise that could revolutionize colorectal cancer screening.

Researchers compared both the adenoma miss rate using the new colonoscope with the miss rate of a traditional colonoscope. The miss rate for the new colonoscope was only 7.6 percent as compared to 41.7 percent for the traditional colonoscope, in this study.

"It's always our goal to minimize miss rates in colonoscopy," said Professor Ian M. Gralnek of the Bruce and Ruth Rappaport Faculty of Medicine, Technion-Israel Institute of Technology and senior physician at the department of gastroenterology, Rambam Health Care Campus and Elisha Hospital in Haifa, Israel. "These results show us a way to achieve that and improve the efficacy of colorectal cancer screening and surveillance colonoscopy."

Developed by EndoChoice, the Full Spectrum Endoscopy (FUSE) colonoscope maintains the identical technical features of the standard colonoscope, but allows the endoscopist to view 330 degrees, compared to the 170 degree viewing angle of the traditional colonoscope.

The study randomly assigned 197 patients for tandem colonoscopies using either the standard or the FUSE colonoscope first. In addition to a significantly lower adenoma miss rate, results showed a significantly higher adenoma detection rate favoring FUSE. Professor Gralnek credits FUSE's improved imaging technology with these findings as adenomas can be difficult to detect with only forward-viewing capabilities.

"Adenomas often hide behind folds in the colon and can be very difficult to find with a forward-viewing scope," Professor Gralnek said.

"Lower adenoma miss rates have important implications for patient surveillance," he added. The additional information FUSE provides to doctors may allow them to adjust patients' surveillance intervals according to risk level, ultimately helping to prevent incremental colorectal cancers. The FUSE scope could be available as early as this summer.

Colonoscopy withdrawal time makes a big difference for diagnosis

DDW also features other advances in colonoscopy relating not to what doctors see, but to how long they look. Researchers at Stanford University compared a three-minute versus six-minute withdrawal time during colonoscopy. The polyp miss rate was almost twice as high during the shorter procedure.

"The de facto standard of care for colonoscopy withdrawal time, which is six minutes, was based on a single observational study," said Sheila Kumar, research fellow in Stanford's division of gastroenterology and hepatology. "More data were needed to ensure that we are providing the best care possible. Our findings provide evidence-based support that prolonging withdrawal time significantly decreases polyp miss rates at colonoscopy."

Dr. Kumar's research represents the first randomized controlled trial examining the effect of colonoscopy withdrawal times on polyp miss rates. The study was conducted with patients undergoing colonoscopies at Stanford and the Palo Alto Veterans Administration Hospital. Patients were randomized to an initial three-minute or six-minute colonoscopy withdrawal time. Patients then underwent a "second look" six-minute withdrawal to determine if polyps were missed with the first look.

"The study design also allowed for data collection for screenings up to 12 minutes long, by combining data for the first and second withdrawal," Dr. Kumar said. "Future comparisons could help to confirm the optimal time parameters of a colonoscopy."

A safer polypectomy option for high-risk patients

In another study, researchers at Showa Inan General Hospital in Komagane, Japan, found that a particular method of polypectomy called a "cold snare" technique is safer for patients on anticoagulants.

When a colon or rectal polyp is detected during colonoscopy, a polypectomy is often recommended to remove the growth. But for patients who use anticoagulants, or blood thinners, polypectomies carry higher risk because of bleeding that occurs during excision of the polyp and recovery.

"The results of our study represent an important opportunity for patients whose options have been severely limited up to this point," said Akira Horiuchi, chief of the hospital's Digestive Disease Center.

The study compared the bleeding associated with the conventional polypectomy technique and the cold snare technique. With the first, the polyp is snared with a wire and then cut using electrocautery. The cold snare technique mechanically cuts off the polyp without electrocautery.

With the latter method, bleeding was seen in only about 5 percent of cases compared to 23 percent of cases using the conventional technique. No delayed bleeding was associated with the cold snare technique, whereas 14 percent of the conventional patients required hemostasis afterward. Polyp removal rates were identical for both approaches.

"These differences are exciting and encouraging," Dr. Horiuchi said. "We think the study paves the way for future research to validate a safer option for many patients."

Professor Gralnek will present data from the study "Comparing traditional forward-viewing colonoscopy with 'full spectrum endoscopy': a randomized, multicenter tandem colonoscopy study - the Fuse study," abstract 9a, on Saturday, May 18, at 9:44 a.m. ET in Room 415 Valencia of the Orange County Convention Center.

Dr. Kumar will present data from the study "Evaluating the optimal time for colonoscopy withdrawal: a prospective randomized comparison of three minute versus six minute withdrawal," abstract Mo1559, on Monday, May 20, at 8 a.m. ET in Hall West A1of the Orange County Convention Center.

Dr. Horiuchi will present data from the study "Prospective randomized comparison of cold snare polypectomy and conventional polypectomy for small colorectal polys in patients receiving anticoagulation therapy," abstract 852, on Monday, May 20, at 4 p.m. ET in Room 314B of the Orange County Convention Center.
