The Great Wall: worth some clicks. Nice kids, good presentations.Funny aside, one of my friends has something like 9 brothers (and no sisters). In Chinese, you would normally refer to them as "oldest brother" or "second oldest brother" and so on. For some reason, they started doing this in English, and would say things like "Hey, how's two doing?"

Pasadena, CA. Blazars are the brightest of active galactic nuclei, and many emit very high-energy gamma rays. New observations of a blazar known as PKS 1424+240 show that it is the most-distant known source of very high-energy gamma rays. But its emission spectrum appears highly unusual.
A team including Carnegie's Michele Fumagalli used data from the Hubble Space Telescope to set a lower limit for the blazar's redshift (z ? 0.6035). An object's redshift value is a measurement of how much the wavelength of the light from it that reaches Earth is stretched by the expansion of the Universe. Thus, it reveals the object's age and distance. This blazar's redshift corresponds to a distance of at least 7.4 billion light-years. Their work will be published by The Astrophysical Journal and is available online.
Over such a great distance, a substantial proportion of the gamma rays should be absorbed by the extragalactic background light, but calculations that account for the expected absorption yield an unexpected emission spectrum for the blazar.
"We're seeing an extraordinarily bright source that does not display the characteristic emission expected from a very high-energy blazar," said lead author Amy Furniss, University of California Santa Cruz.
The findings may indicate something new about the emission mechanisms of blazars, the extragalactic background light, or the propagation of gamma-ray photons over long distances. It was not thought that such high-energy gamma-ray sources could be seen at such great distances. The research should allow scientists to better understand cosmological models that predict the extragalactic background light.
The extragalactic background light (EBL) is the diffuse radiation from all stars and galaxies, a dim but pervasive glow that fills the universe. When a high-energy gamma-ray photon collides with a lower-energy EBL photon, they annihilate and create an electron-positron pair. The farther gamma rays have to travel, the more likely they are to be absorbed by this mechanism. This limits the distance to which sources of very high-energy gamma rays can be detected.
Measuring the EBL directly is extremely difficult because there are so many bright sources of light in our immediate neighborhood. In addition to estimates based on cosmological models, astronomers have used galaxy counts to set a lower limit for the EBL. Using a model close to this lower limit to calculate the expected absorption of very high-energy gamma rays from PKS 1424+240, the team derived an intrinsic gamma-ray emission spectrum for the blazar. The results, however, deviate from the expected emission based on current blazar models, which are thought to result from a relativistic jet of particles powered by matter falling onto a supermassive black hole at the center of the host galaxy.
Gamma rays from PKS 1424+240 were first detected by the Fermi Gamma-ray Space Telescope and subsequently by the ground-based instrument VERITAS (Very Energetic Radiation Imaging Telescope Array System), which is sensitive to gamma-rays in the very high-energy (VHE) band from about 100 GeV to more than 10 TeV. To determine the redshift of the blazar--a measure of how much the light from an object has been stretched to longer wavelengths by the expansion of the universe--the researchers used archival data obtained by the Hubble Space Telescope.

COLUMBUS, Ohio Taking a specific form of a vitamin E supplement can accelerate the health benefits that occur when people quit smoking, new research suggests.
In the small study, improvement in blood vessel function associated with the added vitamin E potentially translates into an estimated 19 percent greater drop in future risk for cardiovascular disease.
Smokers were recruited to participate in a study to quit smoking for seven days, with blood markers of inflammation and blood vessel function measured before and after the trial. After seven days of not smoking, participants saw an increase in their vascular function by an average of 2.8 percent. Those who quit smoking and also took the gamma-tocopherol form of vitamin E showed a 1.5 percent additional improvement in vascular function.
While these changes in vascular function may appear to be small, previous large-scale studies suggest that every 1 percent increase in vascular function or improvement in the blood vessel's ability to dilate translates into a 13 percent drop in risk of developing heart disease later in life.
"This is a very short-term study that shows very promising effects," said Richard Bruno, associate professor of human nutrition at The Ohio State University and senior author of the study.
"The underlying rationale is that we know it takes many years before the risk for cardiovascular disease of a former smoker matches that of a nonsmoker. We hope to develop a therapy to combine with smoking cessation that could accelerate the restoration of vascular function and reduce cardiovascular risk."
The research was presented Tuesday (4/23) at the annual Experimental Biology meeting in Boston.
The supplement in the study is not the same as the average vitamin E available on most store shelves. Vitamin E occurs in eight forms based on their chemical structure, and the most well-known form belongs to a variety called tocopherols. In this study, researchers tested the effects of the gamma-tocopherol form. The most common form of vitamin E, and the one for which humans have a dietary requirement, is alpha-tocopherol.
Though taking gamma-tocopherol is safe, Bruno noted that longer-term studies with more participants would be required to nail down specific dietary recommendations related to smoking cessation.
A total of 30 smokers in their 20s who had smoked at least half a pack per day for a year participated in the study. All participants stopped smoking, and 16 received 500 milligrams daily of gamma-tocopherol while 14 received a placebo.
In addition to taking blood samples, researchers measured vascular function by obtaining ultrasound images of an artery in the upper arm as the vessel responded to a surge of blood flow after circulation in the arm was stopped for five minutes.
The quality of vascular function is defined by the artery's ability to dilate in response to the surge of blood more dilation suggests the vessel has appropriate responses to changes in blood flow.
"Greater dilatory response is an indicator of vascular health. People with a long history of smoking tend to have low vasodilatory responses," Bruno said.
Participants who took the supplements showed greater improvements in vascular function and also had lower levels of two inflammation-related proteins in their blood than did participants who received a placebo.
Bruno said the lower levels of those two proteins in the supplemented participants' blood suggest that the gamma-tocopherol form of vitamin E restores vascular function at least in part by lowering inflammation.
Gamma-tocopherol is abundant in the American diet, but is difficult to obtain from low-calorie sources. Food sources include soybean, canola and some other vegetable oils, and certain nuts such as pistachios, pecans, cashews and peanuts. Supplements that are rich in gamma-tocopherol can be found in specialty stores.

By Steve Holland
WASHINGTON (Reuters) - Their rivalries have helped to define American politics for more than a quarter-century.
And sometimes the complex relationships among the only five people alive who know what it's like to be president of the United States have seemed to be straight out of a soap opera. They have called each other names and blamed one another for the nation's problems.
But when they have a rare meeting in Dallas on Thursday for the opening of former president George W. Bush's library and museum, there will be smiles for the cameras and friendly chatter by President Barack Obama and former presidents Bush, Bill Clinton, George H.W. Bush and Jimmy Carter.
It will be the first time they have all been together since January 2009, when they met in Washington a few days before George W. Bush left office and Obama was sworn in as president.
The library's dedication at Southern Methodist University will be something of a re-emergence for George W. Bush, who has preferred to stay out of the spotlight since leaving Washington after eight tumultuous years in office that followed six years as Texas governor.
"Fourteen years was enough for me," Bush told People Magazine last week. "But I do want to stay engaged in issues that matter to me."
Having served in a stressful job that always seems to age its occupants, the five men share a "common bond that supersedes any short-term policy or political differences," said Karen Hughes, a former top aide to George W. Bush.
That said, this isn't necessarily the friendliest of fraternities.
Obama, a 51-year-old Democrat, twice won election by denouncing Republican George W. Bush's handling of the presidency, from the struggling U.S. economy to wars in Iraq and Afghanistan.
Obama, the nation's first African-American president, also accused fellow Democrat Clinton of injecting race into the 2008 campaign, when Clinton was campaigning in South Carolina for his wife, Hillary, in the Democratic presidential primary.
Republican George W. Bush, 66, criticized Clinton's handling of the economy in defeating Clinton's vice president, Al Gore, in 2000. Clinton used the same economic argument in 1992 to deny a second term to Bush's father, George H.W. Bush.
It was George H.W. Bush, now 88, who had perhaps the most colorful putdown of Clinton and Gore in the 1992 presidential campaign when he said, "My dog Millie knows more about foreign policy than those two Bozos."
'YOU CANNOT GET MAD AT THE GUY'
It took a while for the edge to wear off from that campaign.
When then-President Clinton attended George H.W. Bush's presidential library opening in College Station, Texas in 1997, Clinton aides recall that Bush and his wife, Barbara, were particularly gracious.
On the other hand, their sons, George W. and Jeb, were frosty to the Clinton side, former Clinton press secretary Mike McCurry said.
Five years after Clinton had denied the elder Bush a second term in the White House by casting the Republican as out of touch on the economy, "things were still a little bit raw," McCurry said.
Now, Clinton and George H.W. Bush probably have the closest friendship within the group of presidents. They have worked together to raise money to help those stricken by a 2005 tsunami in the Indian Ocean that killed more than 230,000 people in more than a dozen countries.
"You cannot get mad at the guy," George H.W. Bush wrote of Clinton after traveling with him in 2005. "I admit to wondering why he can't stay on time, but when I see him interacting with folks my wonder turns to understanding, with a dollop of angst thrown in."
The younger Bush now gets along with Clinton, too. They worked together on Haiti earthquake relief in 2010.
"I like him, and I love his father," Clinton said during an appearance with George W. Bush in Salt Lake City last August.
The relationship between the last two presidents, Obama and George W. Bush, remains something of a work in progress, aides said.
The two rarely speak, although Obama was gracious to his predecessor last year when Bush visited the White House for the formal unveiling of his presidential portrait.
"We may have our differences politically, but the presidency transcends those differences," Obama said at the ceremony. "We all love this country. We all want America to succeed."
A senior administration official said that Obama, now in his second term, has not changed his views about what he saw as "poor policy decisions" by Bush on the Iraq war and the U.S. economy. But, the official said, Obama has an appreciation "for the enormity of the decisions that a president has to make and the burden that a president has to bear, especially when Americans lose their lives."
The Bush side, which was not happy at how Obama bashed him during the 2008 campaign, nevertheless is pleased that Obama is joining the group in Dallas.
If there is a wild card in the group, it is Carter.
Aides to Obama and those close to both Bushes and Clinton say the four of them are all a bit baffled and bemused by Carter, 88, who was president from 1977 to 1981, before the late Ronald Reagan's conservative revolution stormed Washington.
Carter has consistently criticized all of his successors, even when they have been fellow Democrats.
"The odd man out is Carter," said Ron Kaufman, a former adviser to the elder Bush.
So what do the presidents talk about when they get together? If the past is any guide, they will keep it light.
Dana Perino, who was a press secretary to George W. Bush, said after the presidents were together in 2009 she asked her boss what they had discussed.
Bush's response: "We mostly talked about our families."

Haters gonna hate -- but how did Gwyneth Paltrow end up topping Lindsay Lohan and Chris Brown as Hollywood's most hated celebrity? The Iron Man 3 actress scored the top spot in Star magazine's annual poll of readers' least favorite stars. Granted, Gwyneth has made herself an easy target by trying to become a lifestyle guru to the little people. But we're not sure that eating lots of kale and being cluelessly privileged is the worst thing a celebrity can do.
