Hubble sees a unique cluster: One of the hidden 15

Apr. 19, 2013 ? Palomar 2 is part of a group of 15 globulars known as the Palomar clusters. These clusters, as the name suggests, were discovered in survey plates from the first Palomar Observatory Sky Survey in the 1950s, a project that involved some of the most well-known astronomers of the day, including Edwin Hubble. They were discovered quite late because they are so faint -- each is either extremely remote, very heavily hidden behind blankets of dust, or has a very small number of remaining stars.

This particular cluster is unique in more than one way. For one, it is the only globular cluster that we see in this part of the sky, the northern constellation of Auriga (The Charioteer). Globular clusters orbit the center of a galaxy like the Milky Way in the same way that satellites circle around the Earth. This means that they normally lie closer in to the galactic center than we do, and so we almost always see them in the same region of the sky. Palomar 2 is an exception to this, as it is around five times further away from the center of the Milky Way than other clusters. It also lies in the opposite direction -- further out than Earth -- and so it is classed as an "outer halo" globular.

It is also unusual due to its apparent dimness. The cluster is veiled by a mask of dust, dampening the apparent brightness of the stars within it and making it appear as a very faint burst of stars. The stunning NASA/ESA Hubble Space Telescope image shows Palomar 2 in a way that could not be captured from smaller or ground-based telescopes -- some amateur astronomers with large telescopes attempt to observe all of the obscure and well-hidden Palomar 15 as a challenge, to see how many they can pick out from the starry sky.

Cutting specific atmospheric pollutants would slow sea level rise

Thursday, April 18, 2013

With coastal areas bracing for rising sea levels, new research indicates that cutting emissions of certain pollutants can greatly slow sea level rise this century.

Scientists found that reductions in four pollutants that cycle comparatively quickly through the atmosphere could temporarily forestall the rate of sea level rise by roughly 25 to 50 percent.

The researchers focused on emissions of four heat-trapping pollutants: methane, tropospheric ozone, hydrofluorocarbons and black carbon.

These gases and particles last anywhere from a week to a decade in the atmosphere and can influence climate more quickly than carbon dioxide, which persists in the atmosphere for centuries.

"To avoid potentially dangerous sea level rise, we could cut emissions of short-lived pollutants even if we cannot immediately cut carbon dioxide emissions," says Aixue Hu of the National Center for Atmospheric Research (NCAR) in Boulder, Colo., first author of a paper published today in the journal Nature Climate Change.

"Society can significantly reduce the threat to coastal cities if it moves quickly on a handful of pollutants."

The research was funded by the National Science Foundation (NSF) and the U.S. Department of Energy.

"Sea level rise and its consequences present enormous challenges to modern society," says Anjuli Bamzai, program director in NSF's Division of Atmospheric and Geospace Sciences, which supported the research.

"This study looks at projections of global sea level rise, unraveling the effects of mitigating short-lived greenhouse gases such as methane, tropospheric ozone, hydrofluorocarbons and black carbon, as well as long-lived greenhouse gases like carbon dioxide," says Bamzai.

It is still not too late, "by stabilizing carbon dioxide concentrations in the atmosphere and reducing emissions of shorter-lived pollutants, to lower the rate of warming and reduce sea level rise by 30 percent," says atmospheric scientist Veerabhadran Ramanathan of the Scripps Institution of Oceanography (SIO) in San Diego, a co-author of the paper. Ramanathan initiated and helped oversee the study.

"The large role of the shorter-lived pollutants is encouraging since technologies are available to drastically cut their emissions," says Ramanathan.

The potential effects of rising oceans on populated areas are of great concern, he says.

Many of the world's major cities, such as New York, Miami, Amsterdam, Mumbai, and Tokyo, are located in low-lying areas along coasts.

As glaciers and ice sheets melt, and warming oceans expand, sea levels have been rising by an average of about 3 millimeters annually in recent years (just over one-tenth of an inch).

If temperatures continue to warm, sea levels are projected to rise between 18 and 200 centimeters (between 7 inches and 6 feet) this century, according to reports by the Intergovernmental Panel on Climate Change and the U.S. National Research Council.

Such an increase could submerge coastal communities, especially when storm surges hit.

Previous research by Ramanathan and Yangyang Xu of SIO, a co-author of the paper, showed that a sharp reduction in emissions of shorter-lived pollutants beginning in 2015 could offset warming temperatures by up to 50 percent by 2050.

Applying those emission reductions to sea level rise, the researchers found that the cuts could dramatically slow rising sea levels.

The results showed that total sea level rise would be reduced by an estimated 22 to 42 percent by 2100, depending on the extent to which emissions were cut.

However, the study also found that delaying emissions cuts until 2040 would reduce the beneficial effect on year-2100 sea level rise by about a third.

If society were able to substantially reduce both emissions of carbon dioxide as well as the four other pollutants, total sea level rise would be lessened by at least 30 percent by 2100, the researchers conclude.

"We still have some control over the amount of sea level rise we are facing," Hu says.

Another paper co-author, Claudia Tebaldi of Climate Central, adds: "Without diminishing the importance of reducing carbon dioxide emissions in the long-term, this study shows that more immediate gains from shorter-lived pollutants are substantial.

"Cutting emissions of those gases could give coastal communities more time to prepare for rising sea levels," says Tebaldi. "As we have seen recently, storm surges in populated regions of the East Coast show the importance of making such preparations and cutting greenhouse gases."

To conduct the study, Hu and colleagues turned to the NCAR-based Community Climate System Model, as well as a second computer model that simulates climate, carbon and geochemistry.

They also drew on estimates of future emissions of heat-trapping gases under various social and economic scenarios and on computer models of melting ice and sea level rise.

The study assumes that society could reduce emissions of the four gases and particles by 30-60 percent over the next several decades.

That is the steepest reduction believed achievable by economists who have studied the issue at Austria's International Institute for Applied Systems Analysis, one of the world's leading research centers into the effects of economic activity on climate change.

"It must be remembered that carbon dioxide is still the most important factor in sea level rise over the long-term," says NCAR scientist Warren Washington, a paper co-author. "But we can make a real difference in the next several decades by reducing other emissions."

One Boston Marathon suspect killed; second suspect, his brother, on loose after firefight

FBI.gov

The two marathon bombing suspects. The man in the white hat is still believed to be at large.

?

By Pete Williams, Richard Esposito, Michael Isikoff and Erin McClam, NBC News

With a bomb strapped to his chest, one of the Boston Marathon suspects was killed early Friday after he and his accomplice brother robbed a 7-Eleven, shot a police officer to death, carjacked an SUV and hurled explosives in an extraordinary firefight with law enforcement, authorities told NBC News.

The second suspect ? the one in the white hat in photos released by the FBI ? was on the loose. Gov. Deval Patrick ordered the entire city of Boston and some suburbs to stay inside during what he called a ?massive manhunt,? and police began a house-to-house search. Boston shut down its buses and subway system.?

The suspects are brothers of Chechen origin with the last name Tsarnaev, law enforcement officials told NBC News. The suspect at large, Dzhokhar Tsarnaev, is 19, was born in Kyrgyzstan and has a Massachusetts driver?s license, they said. The dead suspect was identified as Tamerlan?Tsarnaev, 26, born in Russia.

Tamerlan?Tsarnaev was run over by a vehicle during the firefight, law enforcement officials told NBC News. Law enforcement officials also told NBC News that the brothers entered the United States with family in 2002 or 2003, and that Tamerlan Tsarnaev became a legal permanent resident in 2007.

Suspects in bombings are brothers, authorities say

The chaotic sequence of events started six hours after the FBI triggered a nationwide manhunt by releasing photos of the suspects, believed responsible for detonating two bombs at the marathon finish line Monday, killing three people and injuring 176.

Watertown resident Andrew Kitzenberg says he had a "clear line of view" of what he said looked "like a pressure cooker bomb."

The suspect at large was described by authorities as light-skinned and with brown, curly hair, and wearing a gray hoodie.

?There is a terrorist on the loose,? a law enforcement officer said at a press conference before dawn.

Police shut a 4-mile stretch of streets between Cambridge, Mass., and Watertown because they could be littered with unexploded devices, and they began a door-to-door search in Watertown. A convoy of at least 20 vehicles, including military-style humvees and buses, was seen descending on the town.

Roughly 380,000 people in the Boston suburbs were sheltering in place.

?I just want to speak to the community of Watertown. We need your help now. We are asking everyone to shelter into your place,? Watertown Police Chief Edward Deveau said. ?The Watertown community has always stood strong. We need them to do that today.?

Harvard University, Boston University, the Massachusetts Institute of Technology and Boston public schools all closed. Emerson University closed and told students to stay where they were.

Andrew Kitzenberg, who lives in Watertown, said he saw the two men shooting at six police cars from 70 or 80 yards away.?

?There was a long exchange of gunfire,? told NBC News in an interview. He said that he saw the suspects use what looked like a pressure-cooker bomb.

?I saw them light this bomb. They threw it towards the officers,? he said. ?It created a significant decoy, and there was smoke that covered our entire street.?

Investigators believe at least one of the two bombs that exploded at the marathon finish line was housed in an ordinary kitchen pressure cooker.

Police with guns drawn search for a suspect on April 19, 2013 in Watertown, Mass. Earlier, a Massachusetts Institute of Technology campus police officer was shot and killed late Thursday night at the school's campus in Cambridge. A short time later, police reported exchanging gunfire with alleged carjackers in Watertown, a city near Cambridge. It's not clear whether the shootings are related or whether either are related to the Boston Marathon bombing.

President Barack Obama was briefed overnight on the events, a White House official told NBC News. On Thursday, he spoke at a prayer service for the marathon victims and vowed that the people responsible would be caught.

Law enforcement officials said the tumult began just before 11 p.m., when the suspects approached a police officer from the Massachusetts Institute of Technology and shot him in the head.

The two then stole the officer?s cruiser, robbed a nearby 7-Eleven, carjacked a Mercedes SUV and briefly kidnapped the driver, the sources said. The suspects threw explosives out the window during the chase that followed, they said. A Boston transit police officer was shot and wounded, authorities said.

The dead suspect ? the man in the black hat from the FBI photos ? had an improvised explosive device strapped to his chest, law enforcement officials said.

Kitzenberg said that the firefight ended when one of the shooters ran toward the Watertown officers and ultimately fell to the ground. Kitzenberg said he could not tell whether the man was tackled or had been shot.

The other drove the SUV through a line of police offcers at the end of the street, he said. A bullet from the gunbattle lodged in the wall of Kitzenberg?s apartment, he said.

Kitzenberg said that while he had a clear view of the shooters, he could not see their faces. He described them as ?average size, average height.?

?We heard a loud blast and we didn't know what it was,? said Rebecca Carbone, who stepped out of her home when she heard sirens. ?It sounded like a car backfiring.?

John Grimes, a retired letter carrier, said that he heard three loud explosions, ?and you don?t hear explosions at night a lot.?

How smart are your clothes? Interactive electronic fabrics created

Apr. 16, 2013 ? From corsets to caftans, we have seen dramatic changes in popular style over the past 100 years. New research from Concordia University now brings the future of fashion into focus by taking a closer look at the next quantum leap in textile design: computerized fabrics that change their colour and their shape in response to movement.

?

Joanna Berzowska, professor and chair of the Department of Design and Computation Arts at Concordia, has developed interactive electronic fabrics that harness power directly from the human body, store that energy, and then use it to change the garments? visual properties. ?Our goal is to create garments that can transform in complex and surprising ways ? far beyond reversible jackets, or shirts that change colour in response to heat. That?s why the project is called Karma Chameleon,? says Berzowska.

?

The major innovation of this research project is the ability to embed these electronic or computer functions within the fibre itself: rather than being attached to the textile, the electronic components are woven into these new composite fibres. The fibres consist of multiple layers of polymers, which, when stretched and drawn out to a small diameter, begin to interact with each other. The fabric, produced in collaboration with the ?cole Polytechnique?s Maksim Skorobogatiy, represent a significant advance in the development of ?smart textiles.?

Although it?s not yet possible to manufacture clothing with the new composite fibres, Berzowska worked with fashion designers to create conceptual prototypes that can help us visualize how such clothing might look and behave. ?We won?t see such garments in stores for another 20 or 30 years, but the practical and creative possibilities are exciting,? says Berzowska. Imagine a dress that changes shape and colour on its own, or a shirt that can capture the energy from human movement and use it to charge an iPhone.?

?

There would also be a performative aspect to wearing such garments, whose dramatic transformations may or may not be controlled by the wearer. This research raises interesting questions about human behaviour relative to fashion and computers. What would it mean to wear a piece of clothing with ?a mind of its own,? that cannot be consciously controlled? How much intimate contact with computers do we really want?

?

Berzowska will explore these questions and present her findings at the Smart Fabrics 2013 conference this week in San Francisco. She has also written an article detailing her research for The Fashion Studies Handbook, forthcoming from Berg Publishers. An exhibit, to be held at the PHI Centre in the next year, will give the public an opportunity to learn about her research, and to enter the imaginative space produced by her futuristic fabrics and clothing.

Who Stands Where In A Crowded Elevator And Why?

She's in Finland now, getting her Ph.D. at the University of Jyvaskyla, but before that, when she was in Adelaide, Australia, she studied elevator behavior. Rebekah Rousi hung around two tall office towers in town, riding elevators up and down day after day, looking for patterns. When a bunch of people get into an elevator, she wondered, do they segregate in any predictable way? Do tall ones stand in the back? Do men stand in different places than women? Who looks where? She says she wasn't expecting or even predicting a particular configuration, but she found one.

Over and over, she noticed that older "more senior men in particular seem to direct themselves towards the back of the elevator cabins."

Younger men took up the middle ground.

And in the front, facing the doors, backs to the guys, stood "women of all ages."

She's not sure why. It wasn't segregation by height. It wasn't age, since older and younger women co-mingled. Clearly, the people in the back had the advantage of seeing everybody in the cabin, while people in the front had no idea who was behind them. Could there be a curiosity difference? A predatory difference?

There was a second pattern, one that broke along gender lines. "Men," she wrote, "looked in the side mirrors and the door mirrors" to openly check out the other passengers, and/or themselves.

Women didn't do that. "Women would watch the monitors and avoid eye contact with other users (unless in conversation)." They would only look at the mirrors (where they could check out the other passengers) when they were with other women. Eye-wise, the guys were roving, the ladies weren't.

"That's where I started thinking of power," Rebekah wrote me. The men who flocked to the back, who had a better view of their fellow passengers, were consistently older, more "senior" (I'm not sure how she knew that, but it's in her posted paper) and many of them "weren't concerned with 'getting caught' looking in the mirror." They gazed freely, suggesting a sense of privilege. Younger, less powerful men seemed to avoid that space, choosing a middle ground. The back of the box, (unlike the back of the bus in Alabama civil rights days) she decided, might be the elevator power zone.

Or ...

Perhaps a gender analysis is too easy. Power hierarchies in elevators, she wrote, "almost seemed too clich?." This could be about shyness. Bold people choose the back; shy people the front. Does that mean she thinks Australian women are more self-conscious than Australian men? She wouldn't go there, except to say, "I don't really want people to know how vain I am, so looking in the mirror (as a woman or not) when others are in the lift ... is highly avoided." By this analysis, the back of the elevator is the Vanity-Unleashed zone.

Basically, she's still puzzled. A pattern shows up. But the explanation, she said, slipping into academic shyness, "awaits further analysis." Then she added, "I'd be really interested to hear what your listeners (she means you, you reading this) have to say about the issue."

Iran condemns Boston blast, criticizes US policy

TEHRAN, Iran (AP) ? Iran's top leader on Wednesday condemned the twin bombing attacks in Boston, yet chided the U.S. for employing a double standard when it comes to drone attacks that kill innocent civilians.

"The Islamic Republic of Iran, which follows the logic of Islam, is opposed to any bombings and killings of innocent people no matter if it is in Boston, Pakistan, Afghanistan, Iraq or Syria and condemns it," Ayatollah Ali Khamenei told Iranian military leaders he was addressing in Tehran.

Khamenei criticized the U.S. for killing people with drones in Pakistan and Afghanistan and backing forces that kill others in Iraq and Syria.

"What kind of logic is this that if children and women are killed by Americans in Afghanistan and Pakistan and by U.S.-backed terrorists in Iraq and Syria is not a problem, but if a bombing happens in the U.S. or another Western country, the whole world should pay the cost?" he asked in his comments, which were posted on his website.

Iran is the chief regional ally of Syrian President Bashar Assad and is considered close to Iraq's Shiite Muslim-dominated government.

Khamenei charged that such double standards would lead to the demise of Western civilization.

"Western civilization is on the verge of collapse and downfall because of contradictions, lack of logic, coercions and lack of care for human principles," he said.

After 8-year-old girl protests, Tennessee senator drops bill that links welfare to grades

By Jeff Black, Staff Writer, NBC News

A Tennessee state senator dropped an effort to link welfare to the children's grades after an 8-year-old girl confronted him with a petition -- and a choir -- opposing the bill.

Republican state Sen. Stacey Campfield?s proposal, officially called the "Education to End Poverty Act," was nicknamed the "Starve the Children" bill by opponents and was widely criticized in national and local media.

The bill would have reduced temporary assistance to needy families of children who fail a grade, unless they go through a series of corrective actions, including taking a parenting class, meeting with teachers and enrolling a child in summer school or getting them a tutor.

---

The girl, Aamira Fetuga, confronted Campfield in a Legislature hallway before Thursday?s session. She carried a petition with some 2,500 signatures and was accompanied by a choir of some 60 people who sang ?Jesus Loves the Little Children,? according to the Tennessean.

Campfield reportedly walked away from the girl and the assembled opponents.

?How are you? Thanks for coming,? Campfield told the girl, the Tennessean reported. ?I love it when people use children as props.?

Afterward, on the Senate floor, instead of a vote he moved to have the bill sent to a committee for more study.

For his part, Campfield didn?t admit the girl?s lobbying had anything to do with the delay of the bill.

?I got a lot of good feedback from people,? he said, saying some senators were close to supporting the measure but wanted more information.

Supporters of the measure say the purpose was to spur parents to get involved in their children?s education. Opponents charged it is burden on already-struggling families.

Campfield made headlines earlier this year when he was lampooned by comedian Stephen Colbert for spearheading legislation dubbed "Don't Say Gay."

English Premier League to adopt goal-line technology next season, Hawk-Eye to be the provider

Football's ruling body, FIFA, has already decided that goal-line technology will be used at next year's World Cup in Brazil, which, in and of itself, was an indirect nod for other competitions to follow suit. Today, one of the globe's biggest leagues announced it too will implement the recently approved tech in its matches, with the Premier League letting it be known that the 2013-2014 season is set to be the first to adopt the new system. Speaking of which, the Football Association decided to go with Hawk-Eye, a technology currently present in professional sports like tennis and cricket -- one that provides seven fast-frame shooters around the two goals and uses software to quickly analyze if the ball indeed crossed the line. For the football (soccer) faithful, it's been along time coming, so here's hoping this makes the game less prone to errors. After all, Howard Webb and Mike Dean need all they help they can get.
