NASA Explorer Schools Symposium Showcases Student Research

WASHINGTON -- Students from across the nation will gather at NASA's Kennedy Space Center in Florida May 4-7 for the NASA Explorer Schools symposium. Future leaders in science, technology, education and math, or STEM, will present their work to NASA scientists, engineers, fellow students and educators.

The competitively selected group of fourth through 12th-graders consists of 58 students and 29 educators. The various research projects were designed to improve teaching and bolster interest in STEM disciplines.

"NASA's mission of research and discovery is a powerful context for learning," said NASA Explorer Schools Project manager, Rob LaSalvia. "Each year students amaze us with presentations that mirror the work of our scientists and engineers."

The students were required to complete an original investigation focused on existing NASA missions or research interests. Participants presented their work to experts at virtual regional symposia held January through March at NASA centers using the agency's Digital Learning Network.

In addition to presenting their work at the national symposium, participants also will learn more about NASA's research activities and exploration missions. Students will tour a variety of operational facilities at Kennedy, including the space shuttle launch complex.

The NASA Explorer Schools project offers multiple pathways for participation and requires no application process. Teacher participants must be a U.S. citizen, have a valid education certification as an administrator or educator in a nationally accredited education institution within the United States or territories, Department of Defense or State Department schools.

Chemist Shows How RNA Can Be the Starting Point For Life : 2nd Part

In Dr. Sutherland’s reconstruction, phosphate plays a critical role not only as an ingredient but also as a catalyst and in regulating acidity. Dr. Joyce said he was so impressed by the role of phosphate that “this makes me think of myself not as a carbon-based life form but as a phosphate-based life form.” Dr. Sutherland’s proposal has not convinced everyone. Dr. Robert Shapiro, a chemist at New York University, said the recipe “definitely does not meet my criteria for a plausible pathway to the RNA world.” He said that cyano-acetylene, one of Dr. Sutherland’s assumed starting materials, is quickly destroyed by other chemicals and its appearance in pure form on the early earth “could be considered a fantasy.”Dr. Sutherland replied that the chemical is consumed fastest in the reaction he proposes, and that since it has been detected on Titan there is no reason it should not have been present on the early earth.If Dr. Sutherland’s proposal is correct it will set conditions that should help solve the many other problems in reconstructing the origin of life. Darwin, in a famous letter of 1871 to the botanist Joseph Hooker, surmised that life began in some warm little pond, with all sorts of ammonia and phosphoric salts.” But the warm little pond has given way in recent years to the belief that life began in some exotic environment like the fissures of a volcano or in the deep sea vents that line the ocean floor.Dr. Sutherland’s report supports Darwin. His proposed chemical reaction take place at moderate temperatures, though one goes best at 60 degrees Celsius. “It’s consistent with a warm pond evaporating as the sun comes out,” he said. His scenario would rule out deep sea vents as the place where life originated because it requires ultraviolet light.A serious puzzle about the nature of life is that most of its molecules are right-handed or left-handed, whereas in nature mixtures of both forms exist. Dr. Joyce said he had hoped an explanation for the one-handedness of biological molecules would emerge from prebiotic chemistry, but Dr. Sutherland’s reactions do not supply any such explanation. One is certainly required because of what is known to chemists as “original syn,” referring to a chemical operation that can affect a molecule’s handedness. Dr. Sutherland said he was working on this problem and on others, including how to enclose the primitive RNA molecules in some kind of membrane as the precursor to the first living cell.

Chemist Shows How RNA Can Be the starting Point For Life

An English chemist has found the hidden gateway to the RNA world, the chemical milieu from which the first forms of life are thought to have emerged on earth some 3.8 billion years ago. He has solved a problem that for 20 years has thwarted researchers trying to understand the origin of life — how the building blocks of RNA, called nucleotides, could have spontaneously assembled themselves in the conditions of the primitive earth. The discovery, if correct, should set researchers on the right track to solving many other mysteries about the origin of life. It will also mean that for the first time a plausible explanation exists for how an information-carrying biological molecule could have emerged through natural processes from chemicals on the primitive earth. The author, John D. Sutherland, a chemist at the University of Manchester, likened his work to a crossword puzzle in which doing the first clues makes the others easier. “Whether we’ve done one across is an open question,” he said. “Our worry is that it may not be right.” Other researchers say they believe he has made a major advance in prebiotic chemistry, the study of the natural chemical reactions that preceded the first living cells. “It is precisely because this work opens up so many new directions for research that it will stand for years as one of the great advances in prebiotic chemistry,” Jack Szostak of the Massachusetts General Hospital wrote in a commentary in Nature, where the work is being published on Thursday. Scientists have long suspected that the first forms of life carried their biological information not in DNA but in RNA, its close chemical cousin. Though DNA is better known because of its storage of genetic information, RNA performs many of the trickiest operations in living cells. RNA seems to have delegated the chore of data storage to the chemically more stable DNA eons ago. If the first forms of life were based on RNA, then the issue is to explain how the first RNA molecules were formed.For more than 20 years researchers have been working on this problem. The building blocks of RNA, known as nucleotides, each consist of a chemical base, a sugar molecule called ribose and a phosphate group. Chemists quickly found plausible natural ways for each of these constituents to form from natural chemicals. But there was no natural way for them all to join together. The spontaneous appearance of such nucleotides on the primitive earth “would have been a near miracle,” two leading researchers, Gerald Joyce and Leslie Orgel, wrote in 1999. Others were so despairing that they believed some other molecule must have preceded RNA and started looking for a pre-RNA world.The miracle seems now to have been explained. In the article in Nature, Dr. Sutherland and his colleagues Matthew W. Powner and Béatrice Gerland report that they have taken the same starting chemicals used by others but have caused them to react in a different order and in different combinations than in previous experiments. they discovered their recipe, which is far from intuitive, after 10 years of working through every possible combination of starting chemicals. Instead of making the starting chemicals form a sugar and a base, they mixed them in a different order, in which the chemicals naturally formed a compound that is half-sugar and half-base. When another half-sugar and half-base are added, the RNA nucleotide called ribocytidine phosphate emerges. A second nucleotide is created if ultraviolet light is shined on the mixture. Dr. Sutherland said he had not yet found natural ways to generate the other two types of nucleotides found in RNA molecules, but synthesis of the first two was thought to be harder to achieve. If all four nucleotides formed naturally, they would zip together easily to form an RNA molecule with a backbone of alternating sugar and phosphate groups. The bases attached to the sugar constitute a four-letter alphabet in which biological information can be represented.“My assumption is that we are here on this planet as a fundamental consequence of organic chemistry,” Dr. Sutherland said. “So it must be chemistry that wants to work.”The reactions he has described look convincing to most other chemists. “The chemistry is very robust — all the yields are good and the chemistry is simple,” said Dr. Joyce, an expert on the chemical origin of life at the Scripps Research Institute in La Jolla, Calif.

Utah State. The Aggies' non-conference schedule was relatively weak, but they did win 24 of their first 25 games this season and do have a legitimate frontcourt in the 26-year-old forward Gary Wilkinson (17.1 points and 6.9 rebounds) and forward Tai Wesley (11.9 points 6.1 rebounds). Under the 11th-year Coach Stew Morrill, they have won at least 23 games in 10 consecutive seasons, which is only matched by Kansas and Gonzaga. Morrill is due for another win in the N.C.A.A. tournament. His team upset Ohio State in the first round of the N.C.A.A. tournament in 2001 and nearly did the same two years later to national runner-up Kansas. They play Marquette in Boise, Idaho, in the first round this year.

Sharif joins Pakistan protesters

Nawaz Sharif speaks to supporters and journalists in Lahore - 15/3/2009
Nawaz Sharif has been a long-term opponent of the President Zardari

Pakistani opposition leader Nawaz Sharif has joined supporters on a march to the capital Islamabad to stage an anti-government protest.

Hours ahead of the planned march, there were reports that President Asif Ali Zardari was about to reinstate sacked Chief Justice Iftikhar Chaudhry.

The reinstatement of Mr Chaudhry and other judges has been a key opposition demand amid a growing political crisis.

Mr Sharif earlier defied an apparent bid to place him under house arrest.

Hundreds of police had surrounded his home in Lahore but the government denied that he was being detained.

There were clashes as police fired tear gas and baton charged Sharif supporters who threw stones at the police.

Sharif activists later managed to overcome barriers blocking access to the main highway to Islamabad and Mr Sharif left Lahore in a convoy.

Power struggle

Mr Sharif's party, the Pakistan Muslim League (PML-N), has been planning a "long march" to arrive in Islamabad on Monday to stage a sit-in to demand the reinstatement of judges sacked by former President Pervez Musharraf.

Iftikhar Chaudhry

Mr Sharif is expected to arrive in Rawalpindi - near Islamabad - in the early hours of Monday.

He is due to be joined there by his brother, Shahbaz Sharif, former chief minister of the Punjab, and leaders of the lawyers' movement demanding the judges' reinstatement.

President Zardari, Prime Minister Yousuf Raza Gilani and army chiefs were reported to be holding overnight talks aimed at thrashing out a deal to restore Mr Chaudhry and about 60 other judges sacked by Gen Musharraf.

An announcement on the outcome of the talks was expected shortly.

The campaign over the judges has become a power struggle between Mr Sharif and President Zardari, says the BBC's Barbara Plett in Islamabad.

The government has arrested hundreds of opposition activists and banned rallies, saying they could trigger violence.

Our correspondent says it is not clear if Mr Sharif will be able to reach Islamabad, given the authorities have blocked routes leading to the capital.

map

She says the unrest has alarmed the West, which wants Pakistan to focus on the battle against the Taleban on the Afghan border.

The tensions between Mr Zardari and Mr Sharif date back to the 1990s, but the two formed a brief partnership in government after parliamentary elections in February 2008.

President Zardari had promised to bring back the judges when he took office last year following his wife's assassination.

But Mr Sharif's party later left the alliance, complaining of reluctance by Mr Zardari's Pakistan People's Party to reinstate the sacked judges.

The latest crisis was sparked by a Supreme Court decision to ban Mr Sharif and his brother Shahbaz from elected office, and President Zardari's decision to put their stronghold in Punjab province under direct rule from Islamabad.

G20 make pledge to restore growth
Finance ministers from the G20 group of rich and emerging nations have pledged to make a "sustained effort" to pull the world economy out of recession.

"We are committed to deliver the scale of sustained effort necessary to restore growth," they said in a joint statement after their talks in the UK.

UK Chancellor Alistair Darling said they agreed the International Monetary Fund (IMF) should be given more money.

The talks were held amid reports of rifts over the best way forward.

BBC economics editor Stephanie Flanders said that the outline agreements represented "cheap talk", and differences remain.

The outline agreements will now provide the basis for more concrete pledges at next month's meeting of G20 leaders in London.

'Decisive action'

Speaking after the gathering of finance ministers in Horsham, West Sussex, Mr Darling, said the G20 recognised the "sense of emergency" surrounding the world economy.

"We have taken decisive and comprehensive action to boost demand and jobs," he said.

"We are prepared to take whatever action is necessary."

The outline agreements released in the joint communique include a commitment to fighting all forms of protectionism, and the restoration of bank lending.

Remade in America
Where Education and Assimilation Collide

Published: March 14, 2009

WOODBRIDGE, Va. — Walking the halls of Cecil D. Hylton High School outside Washington, it is hard to detect any trace of the divisions that once seemed fixtures in American society.
Two girls, a Muslim in a headscarf and a strawberry blonde in tight jeans, stroll arm in arm. A Hispanic boy wearing a Barack Obama
But as old divisions vanish, waves of immigration have fueled new ones between those who speak English and those who are learning how.
Walk with immigrant students, and the rest of Hylton feels a world apart. By design, they attend classes almost exclusively with one another. They take separate field trips. And they organize separate clubs.
"I am thankful to my teachers because the little bit of English I am able to speak, I speak because of them," Amalia Raymundo, from Guatemala, said during a break between classes. But, she added, "I feel they hold me back by isolating me."
Her best friend, Jhosselin Guevara, also from Guatemala, joined in. "Maybe the teachers are trying to protect us." she said. "There are people who do not want us here at all."
In the last decade, record numbers of immigrants, both legal and illegal, have fueled the greatest growth in public schools since the baby boom. The influx has strained many districts' budgets and resources and put classrooms on the front lines of America's battles over whether and how to assimilate the newcomers and their children.
Inside schools, which are required to enroll students regardless of their immigration status and are prohibited from even asking about it, the debate has turned to how best to educate them.
Hylton High, where a reporter for The New York Times spent much of the past year, is a vivid laboratory. Like thousands of other schools across the country, it has responded to the surge of immigrants by channeling them into a school within a school. It is, in effect, a contemporary form of segregation that provides students learning English intensive support to meet rising academic standards — and it also helps keep the peace.
In a nation where most students learning English lag behind other groups by almost every measure, Hylton's program stands out for its students' high test scores and graduation rates. However, at this ordinary American high school, in an ordinary American suburb at a time of extraordinary upheaval, those achievements come with considerable costs.
The calm in the hallways belies resentments simmering among students who barely know one another. They readily label one another "stupid" or "racist." The tensions have at times erupted into walkouts and cafeteria fights, including one in which immigrant students tore an American flag off the wall and black students responded by shouting, "Go back to your own country!"
Hylton's faculty has been torn over how to educate its immigrant population. Some say the students are unfairly coddled and should be forced more quickly into the mainstream. And even those who support segregating students admit to soul-searching over whether the program serves the school's needs at the expense of immigrant students, who are relentlessly drilled and tutored on material that appears on state tests but get rare exposure to the kinds of courses, demands or experiences that might better prepare them to move up in American society.
"This is hard for us," said Carolyn Custard, Hylton's principal. "I'm not completely convinced we're right. I don't want them to be separated, but at the same time, I want them to succeed."
Education officials classify some 5.1 million students in the United States — 1 in 10 of all those enrolled in public schools — as English language learners, a 60 percent increase from 1995 to 2005.

Researchers give many causes for the gaps between them and other groups. Perhaps most paradoxical, they say, is that a nation that prides itself on being a melting pot has yet to reach agreement on the best way to teach immigrant students.
In recent years, students learning English have flooded into small towns and suburban school districts that have little experience with international diversity. Meanwhile, teachers and administrators have come under increasing pressure to meet the requirements of the federal No Child Left Behind Act, which links every school's financing and its teachers' jobs to student performance on standardized tests.
The challenges have only intensified with a souring economy and deepening anger over illegal immigration, provoking many Americans to questionwhether those living here unlawfully should be educated at all.

Gunman Kills at Least 10 in Alabama,
 Then Takes His Own Life After a Chase
A gunman shot and killed at least 10 people, including several members of his family, on Tuesday afternoon in what officials said was the worst shooting in Alabama.
The gunman led the police on a chase through Geneva County in southern Alabama, firing at officers before fatally shooting himself at a business where he was once employed, law enforcement officials said.

Witnesses of the shootings and their aftermath described a man with multiple weapons who engaged in heavy gunfire, leaving behind blood-soaked porches and bodies.

"It is truly one of the most horrific things that anyone in law enforcement can remember in Alabama," said Col. J. Christopher Murphy, the director of the state's Public Safety Department. "We're still getting victims coming in."

The Associated Press quoted Robert Preachers, the coroner of Coffee County, just north of Geneva County, as identifying the gunman as Michael McLendon. Mr. Preachers said the man burned down the house of his mother, Lisa McLendon, in Kinston. Officials found the woman's body inside the house, The AP said.

"He started in his mother's house," Mr. Preachers said. "Then he went to Samson and he killed his granny and granddaddy and aunt and uncle. He cleaned his family out."

In Samson, four adults and a child were found shot to death at one residence and two people were found dead at two other homes, all shot on their porches, the authorities said.

Another person was found dead at a business, Samson Pipe and Supply, and still another at a service station.

A neighbor who would not give her name for publication said the gunman had also killed his girlfriend.

"I heard pop, pop, pop, pop, and my daughter called me," the woman said. "I'm sickly and old and she said, "Mother, lock your doors and stay inside.' She said there's a man on a rampage shooting."

Another victim was described by a neighbor, Koren Garcia, as a 23-year-old man who had two children and one on the way.

He was walking down the street and stopped to talk to a neighbor as the gunman drove past, she said.

The wife and baby of a sheriff's deputy were also among the dead, said Sheriff Greg Ward of Geneva County. The mother and child were visiting neighbors when they were shot, he said.

"I don't know how we're going to get through this," Ms. Garcia said. "I have no idea. Nothing like this has ever happened. Everyone is crying."

Chased by the police, the gunman drove 12 miles to Geneva on Highway 52, then turned onto Highway 27.

The Geneva County coroner, Max Motley, told the Dothan Eagle that he had been called to the Big Little Store on West Main Street in Samson, where he found the body of a woman between the gas pump and the front door. She was found face up with at least one fatal gunshot wound.

Along the way, the gunman's car was rammed by a police car, and the gunman fired two shots, narrowly missing the officer driving, said Mayor Wynnton Melton of Geneva, whose police officers were involved in the chase.

The police tried to stop the gunman near a Wal-Mart store, where he shot Chief Frankie Lindsey of the Geneva Police Department, grazing his shoulder. The chief's bulletproof vest protected him, officials said.

When the gunman drove past a nearby grocery store, Sheriff Ward fired at him, officials said.

The gunman continued on Highway 27 to Reliable Products, a metal fabricator, outside Geneva, where he was once employed, Sheriff Ward said.

The sheriff said he did not know how recently the gunman had worked there. In the parking lot, the gunman fired about 30 rounds, officials said, then entered the building, where he fatally shot himself, the police said.

Trymaine Lee and Dana Beyerle contributed reporting.

They Tried to Outsmart Wall Street

http://www.nytimes.com/2009/03/10/science/10quant.html?ref=science
Emanuel Derman expected to feel a letdown when he left particle physics for a job on Wall Street in 1985.

After all, for almost 20 years, as a graduate student at Columbia and a postdoctoral fellow at institutions like Oxford and the University of Colorado, he had been a spear carrier in the quest to unify the forces of nature and establish the elusive and Einsteinian "theory of everything," hobnobbing with Nobel laureates and other distinguished thinkers. How could managing money compare?

But the letdown never happened. Instead he fell in love with a corner of finance that dealt with stock options.

"Options theory is kind of deep in some way. It was very elegant; it had the quality of physics," Dr. Derman explained recently with a tinge of wistfulness, sitting in his office at Columbia, where he is now a professor of finance and a risk management consultant with Prisma Capital Partners.

Dr. Derman, who spent 17 years at Goldman Sachs and became managing director, was a forerunner of the many physicists and other scientists who have flooded Wall Street in recent years, moving from a world in which a discrepancy of a few percentage points in a measurement can mean a Nobel Prize or unending mockery to a world in which a few percent one way can land you in jail and a few percent the other way can win you your own private Caribbean island.

They are known as "quants" because they do quantitative finance. Seduced by a vision of mathematical elegance underlying some of the messiest of human activities, they apply skills they once hoped to use to untangle string theory or the nervous system to making money.

This flood seems to be continuing, unabated by the ongoing economic collapse in this country and abroad. Last fall students filled a giant classroom at M.I.T. to overflowing for an evening workshop called "So You Want to Be a Quant." Some quants analyze the stock market. Others churn out the computer models that analyze otherwise unmeasurable risks and profits of arcane deals, or run their own hedge funds and sift through vast universes of data for the slight disparities that can give them an edge.

Still others have opened an academic front, using complexity theory or artificial intelligence to better understand the behavior of humans in markets. In December the physics Web site arXiv.org, where physicists post their papers, added a section for papers on finance. Submissions on subjects like "the superstatistics of labor productivity" and "stochastic volatility models" have been streaming in.

Quants occupy a revealing niche in modern capitalism. They make a lot of money but not as much as the traders who tease them and treat them like geeks. Until recently they rarely made partner at places like Goldman Sachs. In some quarters they get blamed for the current breakdown — "All I can say is, beware of geeks bearing formulas," Warren Buffett said on "The Charlie Rose Show" last fall. Even the quants tend to agree that what they do is not quite science.

As Dr. Derman put it in his book "My Life as a Quant: Reflections on Physics and Finance," "In physics there may one day be a Theory of Everything; in finance and the social sciences, you're lucky if there is a useable theory of anything."

Asked to compare her work to physics, one quant, who requested anonymity because her company had not given her permission to talk to reporters, termed the market "a wild beast" that cannot be controlled, and then added: "It's not like building a bridge. If you're right more than half the time you're winning the game." There are a thousand physicists on Wall Street, she estimated, and many, she said, talk nostalgically about science. "They sold their souls to the devil," she said, adding, "I haven't met many quants who said they were in finance because they were in love with finance."

The Physics of Money

Physicists began to follow the jobs from academia to Wall Street in the late 1970s, when the post-Sputnik boom in science spending had tapered off and the college teaching ranks had been filled with graduates from the 1960s. The result, as Dr. Derman said, was a pipeline with no jobs at the end. Things got even worse after the cold war ended and Congress canceled the Superconducting Supercollider, which would have been the world's biggest particle accelerator, in 1993.

They arrived on Wall Street in the midst of a financial revolution. Among other things, galloping inflation had made finances more complicated and risky, and it required increasingly sophisticated mathematical expertise to parse even simple investments like bonds. Enter the quant.

"Bonds have a price and a stream of payments — a lot of numbers," said Dr. Derman, whose first job was to write a computer program to calculate the prices of bond options. The first time he tried to show it off, the screen froze, but his boss was fascinated anyway by the graphical user interface, a novelty on Wall Street at the time.

Stock options, however, were where this revolution was to have its greatest, and paradigmatic, success. In the 1970s the late Fischer Black of Goldman Sachs, Myron S. Scholes of Stanford and Robert C. Merton of Harvard had figured out how to price and hedge these options in a way that seemed to guarantee profits. The so-called Black-Scholes model has been the quants' gold standard ever since.

In the old days, Dr. Derman explained, if you thought a stock was going to go up, an option was a good deal. But with Black-Scholes, it doesn't matter where the stock is going. Assuming that the price of the stock fluctuates randomly from day to day, the model provides a prescription for you to still win by buying and selling the underlying stock and its bonds.

"If you're a trading desk," Dr. Derman explained, "you don't care if it goes up or down; you still have a recipe."

Bomber Kills Dozens in Iraq as Fears of New Violence Rise

Published: March 10, 2009

BAGHDAD — A suicide bomber took aim at a group of Iraqi army officers on their way to a reconciliation conference, killing 33 people on Tuesday and raising concerns about an increase in insurgent activity in Iraq. It was the second attack since Sunday to kill more than two dozen people.

An eyewitness said the Tuesday attack was carried out by a person wearing a national police uniform who struck a group of officials in a marketplace near the municipal building in Abu Ghraib, on the western outskirts of the capital. The Iraqi Interior Ministry put the death toll at 33, with 46 injured. Two days earlier, on Sunday, a suicide bomber killed 28 people in Baghdad.

The bombings suggest a renewed ability by insurgents to mount more effective suicide bombings, after a long period in which such attacks were relatively few and less lethal because of heavy security precautions.

Tuesday's incident occurred in the early afternoon as the local Iraqi army leaders were on their way to a scheduled reconciliation conference in the District Council with Sunni tribal leaders in the area, according to army officers at the scene.

After the bombing, as people gathered to help the injured, groups of armed men opened fire, killing some of those who survived the bombing, according to Mujasha al-Tamini, the chief editor of Al Iraqiya, a satellite television network that had two reporters at the scene.

A correspondent and a photographer for another Iraqi television network, Al Baghdadiya, were killed in the attack. The Iraqi army lost at least seven men including the commander of the third regiment, Lt. Col. Muhammed Jassim. The commander of the Al Muthanna Brigade, Staff Col. Murad Kareem, was injured, and his brother, who was his bodyguard, was killed, military officials said.

The two recent bombings, and one last week in Babil Province, have had sharply higher death tolls than most others in the past several months, suggesting that extremists have been able to figure out ways to penetrate the heavy security that now surrounds all public functions in Iraq. They also raised questions about whether the insurgency has reinvigorated its operations in Iraq after a long period of relative decline.

Also on Tuesday, a suicide car bomber in the Hamdaniya district of Ninevah province east of Mosul attacked a police patrol, killing three people, including an Iraqi army soldier who was standing near the explosion. The area is mainly Christian, but also is home to Kurds and to Arabs who were displaced from Mosul.

'Dozens dead' in Baghdad bombing

At least 33 people, including a local army chief, have died and 46 have been injured in a suicide attack in western Baghdad, security officials say.

The attack took place in the Abu Ghraib district, and appeared to target a group of dignitaries attending a national reconciliation conference.

Violence levels have declined in Iraq recently, but there have been several fatal attacks in the last few days.

At least 28 died in an attack on a police recruitment centre on Sunday.

The BBC's Mike Sergeant in Baghdad says it is too soon to say whether the attacks constitute a pattern but they show that life in Iraq is still dangerous.

Police sources said police, soldiers and journalists were among the dead in the latest attack.

Reuters news agency said a journalist for the independent al-Baghdadiya TV station was killed.

But there is some confusion about whether the bomber was at the conference, which took place inside Abu Ghraib's town hall, or attacked delegates as they were leaving.

The building is about 25km (15 miles) from the centre of Baghdad, and close to the prison facility which came under scrutiny following abuse of prisoners by US troops after the 2003 invasion.

The latest attack comes days after the US military said it was to reduce troop numbers in the country by 12,000 in the next six months.

Iraq has massively expanded its police and military forces over recent years as the government of Prime Minister Nouri al-Maliki seeks to ensure local forces can provide security amid the envisaged draw-down.

Obama’s Budget Faces Test Among Party Barons

Published: March 9, 2009

WASHINGTON — What the Democratic barons of Congress liked best about President Obama’s audacious budget was his invitation to fill in the details. They have started by erasing some of his.

The apparent first casualty is a big one: a proposal to limit tax deductions for the wealthiest 1.2 percent of taxpayers. Mr. Obama says the plan would produce $318 billion over the next decade as a down payment for overhauling health care.

But the chairmen of the House and Senate tax-writing committees, Senator Max Baucus of Montana and Representative Charles B. Rangel of New York, have objected to the proposal, citing a potential drop in tax-deductible gifts to charities.

Billions in savings from cutting government subsidies to big farmers and agribusinesses? No dice, said Senator Kent Conrad of North Dakota, who heads the Senate Budget Committee.

Mr. Conrad also panned the limit on tax deductions. And his criticisms of those savings proposals aside, Mr. Conrad said Mr. Obama’s 10-year plan would not do enough to reduce future debt.

Shrink spending on Medicare, Medicaid and Social Security? Representative John M. Spratt Jr. of South Carolina, chairman of the House Budget Committee, suggested Mr. Obama’s proposals did not go far enough.

Cap industries’ emissions of the gases blamed for climate change? Representative Henry A. Waxman of California, who leads the House Energy and Commerce Committee, will have to contend with dissent on a panel with Democrats from coal and manufacturing states.

“The legislative process requires compromise and being open to different alternatives,” Mr. Waxman said.

Mr. Obama is taking a gamble in outsourcing the drafting of his agenda’s details to these five veteran lawmakers and others in Congress, each with his own political and parochial calculations.

“This is not an easy budget to market, for sure,” Mr. Spratt said.

He said he and other Democratic leaders would have to sell it one lawmaker at a time, but sell it they would. “Not every problem is a deal breaker,” Mr. Spratt said. “We will try and make corrections and accommodations.”

The process is like “a giant jigsaw puzzle,” Mr. Rangel said. “But it is going to come together.”

If the budget is to come together, the responsibility will be on the Democratic committee chairmen to deliver since most Republicans seem to have little appetite for the president’s proposals.

After a $787 billion economic stimulus package and a $410 billion appropriations measure for the current year, “Republicans feel like they can oppose this spending spree and this shifting of power from Main Street to Washington enthusiastically,” said Senator Lindsey Graham, a Republican from South Carolina to whom the administration has looked for bipartisanship. “It means the year could be an ideological struggle instead of a problem-solving year.”

The House and Senate are aiming to agree on a budget in April, but it will not require Mr. Obama’s signature.

Instead, that budget serves as a nonbinding blueprint for the committees — chiefly the Ways and Means and Finance panels — to write the legislation that Mr. Obama would sign into law. The changes he envisions for health care, energy, taxes, education, transportation and more have stymied Congress for years; in his budget, they come packaged together, and the resistance will be multiplied as a result.

The White House, meanwhile, is making clear that it is ready to push back, judging by its reaction to the strong resistance to its proposal to limit wealthy taxpayers’ deductions.

When Mr. Baucus, the chairman of the Senate Finance Committee, told Timothy F. Geithner, the Treasury secretary, soon after the Obama budget’s release that the administration must find a more “viable” source of revenue for its health care plan, Mr. Geithner expressed openness to other options.

The next day, however, Mr. Geithner staunchly defended the proposed limit, telling the House Budget Committee it would affect few taxpayers and still let them take deductions at the same level as in the Reagan years: a 28 percent rate, nearly twice what most taxpayers can claim.

The White House has sought to broaden that defense, emphasizing that the impact on charitable giving is likely to be small and that the proposal is hardly radical. Mr. Geithner has called it “fair and reasonable.”

Mr. Baucus, a veteran of 34 years in Congress, has welcomed Mr. Obama’s determination to overhaul health care this year. But he also has been drafting his own plan to contain costs and expand insurance coverage, putting him in potential conflict not only with the White House, but also with Senator Edward M. Kennedy, Democrat of Massachusetts and the chairman of the Senate health committee.

For instance, Mr. Baucus has suggested that one way to raise money would be to tax as income the value of the health insurance some employees get on the job, an approach Mr. Obama attacked when Senator John McCain, his Republican rival for the presidency last fall, proposed it.

For Mr. Conrad and some other Democrats, the political problem is that the upfront costs of health care reforms are huge while the promised cost savings are years in the future.

“When people say we won’t see the results of any of that spending for 10 years, I become skeptical,” Mr. Conrad said.

Early meetings of representatives of his Budget Committee and the Senate’s finance and health committees, Mr. Conrad said, have made for “very lively debates.”

As difficult as addressing health care will be, the energy issue may prove even more contentious and from the perspective of many lawmakers is the element of the administration’s agenda most likely to be set aside temporarily if a major initiative must be sacrificed to push through other programs.

To spur development of alternative energy, reduce dependence on foreign oil and help arrest climate change, Mr. Obama proposes a cap-and-trade system after 2011 that would require polluting industries to buy permits to emit carbon dioxide and other heat-trapping gases. Because companies would pass on the costs to customers, most of the revenues from auctioning permits would go to payments to low-wage and middle-income workers to offset their higher utility bills and other expenses. The rest would pay for alternative energy programs.

Republicans are already digging in against Mr. Obama’s approach, opposing both mandates that businesses buy pollution permits, and the idea of tax refunds to workers who earn too little to pay income taxes.

Democrats have their own divisions on energy legislation. Further complicating matters is the fact that Mr. Rangel, who will have to share responsibility for health care with Mr. Waxman, wants his panel to have a piece of the energy policy fight as well. Both men say they can resolve such territorial disputes.

“We are going to have to work out whatever issues there are,” Mr. Waxman said.
