Islamic militants help seize missile base in Syria

BEIRUT (AP) ? Fighters from a shadowy militant group with suspected links to al-Qaida joined Syrian rebels in seizing a government missile defense base in northern Syria on Friday, according to activists and amateur video.

It was unclear if the rebels were able to hold the base after the attack, and analysts questioned whether they would be able to make use of any of the missiles they may have spirited away.

Nevertheless, the assault underscored fears of advanced weaponry falling into the hands of extremists playing an increasingly large role in Syria's civil war.

Videos purportedly shot inside the air defense base and posted online stated that the extremist group, Jabhat al-Nusra, participated in the overnight battle near the village of al-Taaneh, five kilometers (three miles) east of the country's largest city, Aleppo. The videos show dozens of fighters inside the base near a radar tower, along with rows of large missiles, some on the backs of trucks.

A report by a correspondent with the Arabic satellite network Al-Jazeera who visited the base Friday said Jabhat al-Nusra took the lead in the attack, killing three guards and taking others prisoner before seizing the base. The report showed a number of missiles and charred buildings, as well as fighters wearing black masks.

Two Aleppo-based activists and Rami Abdul-Rahman, head of the Syrian Observatory for Human Rights, also said Jabhat al-Nusra fought in the battle with other rebel groups. They disputed the notion that the extremist group had the lead role in the attack, however.

It was impossible to independently verify the videos and conflicting reports because of restrictions on reporting in Syria.

Despite Western opposition to President Bashar Assad's regime, the U.S. and other countries have cited the presence of extremists among the rebels as a reason not to supply the Syrian insurgents with weapons. They have repeatedly cited concerns of heavy weaponry falling into wrong hands.

Rebel leaders argue that arms shortages mean they'll take aid from whoever offers it, regardless of their ideology.

The capture of the base also plays into fears about extremists acquiring Syria's chemical and biological weapons ? particularly if the Assad regime collapses and loses control of them.

Neighboring Jordan's King Abdullah II fears such weapons could go to al-Qaida or other militants, primarily the Iranian-allied Lebanese Hezbollah. The U.S. has sent about 150 troops to Jordan, largely Army special operations forces, to bolster the kingdom's military capabilities in the event Syria's civil war escalates.

Syria is believed to have one of the world's largest chemical weapons programs, and the regime has said it might use the weapons against external threats, though not against Syrians.

Western powers ? and many Syrians ? worry that Islamist extremists are playing an increasing role in Syria's civil war, which started in March 2011 as a mostly peaceful uprising against Assad.

Little is known about Jabhat al-Nusra, or the Support Front, which began claiming attacks in Syria earlier this year in postings on jihadi forums often used by al-Qaida. While neither group has officially acknowledged a link to the other, analysts say al-Nusra's tactics, rhetoric and use of al-Qaida forums point to an affiliation.

Activists on the ground say the group is known for fighting on the front lines in harsh battles and goes out of its way not to show up in activist videos.

"Most brigades want to be filmed in operations so they can get support, but al-Nusra doesn't allow any filming," Aleppo activist Mohammed Abu Omar said via Skype.

The base captured Friday is part of the large air defense infrastructure Syria has built across the country over the years, mostly for use in a possible war with archenemy Israel.

Last week, the rebels reported seizing another air defense base outside the capital, Damascus, as well as a base in the southern province of Daraa. Online videos show them torching vehicles and seizing dozens of boxes of ammunition in the Daraa base.

The storming of these bases by the poorly armed rebels is an embarrassment to the Assad regime, but analysts say the missiles are unlikely to benefit the insurgents.

Pieter Wezeman of the Stockholm International Peace Research Institute identified the missiles in Friday's video as S-75 surface-to-air missiles, which he said are old and hard to move and fire.

"They are outdated and difficult to operate, just not made for use by guerrilla forces not trained in using these things," he said.

The regime, which has received much more advanced surface-to-air missiles from Russia in recent years, probably did not make defending the site a priority, he said.

It also remains unclear if the rebels held the base after storming it. Rebel forces are largely helpless against the regime's attack jets and helicopters, which bomb rebel and civilians areas daily.

One Aleppo activist said the rebels had taken all the munitions they could from the base, and he hoped they could find a way to use the missiles against Assad's air force.

"We have asked all countries to help us with anti-aircraft weapons and no one has, so hopefully these will help," said the activist, Mohammed Saeed.

In any case, it was not clear how much the rebels would be able to make use of the missiles.

"Anyone trying to use these will need to be extremely well trained both in fueling up the missiles and then tracking the target and using the fire control radar," said Jim O'Halloran, an expert in air defense systems at IHS Jane's.

Meanwhile, the fallout deepened from a Syrian passenger jet forced to land in neighboring Turkey, as Russia said the plane traveling from Moscow to Damascus was carrying radar parts that were being transported legally.

Russian Foreign Minister Sergey Lavrov insisted the plane was carrying a legitimate cargo of "electric equipment for radars," but he added that it was of "dual purpose," meaning it could have civilian and military applications.

"It's not forbidden by any international conventions," Lavrov said, adding that the Russian company that sent it to Syria will demand that Turkey return the cargo. He didn't name the Russian company or the cargo's recipient in Syria.

Russia has been Assad's main supporter and ally, shielding him from international sanctions over his crackdown on the uprising.

Turkey's prime minister has said the plane was carrying ammunition and military equipment for the Syrian Defense Ministry. Turkish fighter jets intercepted the Syrian Airbus A320 on Wednesday amid heightened tensions between Turkey and Syria, fueled by recent cross-border shelling from Syria that killed five Turkish civilians.

Tensions continued Friday as Turkey's military scrambled two F-16 fighter jets after a Syrian attack helicopter was seen over a Syrian border town where rebels and regime troops have been clashing for days, Turkey's Dogan news agency reported.

It said the jets were sent to the border to prevent a possible incursion into Turkey by the helicopter, which soon disappeared from view.

Turkey's Foreign Ministry and military did not immediately confirm the report.

The Syrian Observatory for Human Rights said it recorded on Thursday its highest one-day death toll for government soldiers ? 92 ? since the start of the conflict.

It said most of the deaths took place in Idlib province, where some 20 soldiers were killed in a rebel attack on a government checkpoint.

Activists say more than 32,000 people have been killed as the conflict has evolved from a peaceful uprising to a brutal battle between rebels and government troops. Hundreds of thousands of Syrians have fled the fighting to neighboring countries.

Simulations uncover 'flashy' secrets of merging black holes

ScienceDaily (Sep. 27, 2012) ? According to Einstein, whenever massive objects interact, they produce gravitational waves -- distortions in the very fabric of space and time -- that ripple outward across the universe at the speed of light. While astronomers have found indirect evidence of these disturbances, the waves have so far eluded direct detection. Ground-based observatories designed to find them are on the verge of achieving greater sensitivities, and many scientists think that this discovery is just a few years away.

Catching gravitational waves from some of the strongest sources -- colliding black holes with millions of times the sun's mass -- will take a little longer. These waves undulate so slowly that they won't be detectable by ground-based facilities. Instead, scientists will need much larger space-based instruments, such as the proposed Laser Interferometer Space Antenna, which was endorsed as a high-priority future project by the astronomical community.

A team that includes astrophysicists at NASA's Goddard Space Flight Center in Greenbelt, Md., is looking forward to that day by using computational models to explore the mergers of supersized black holes. Their most recent work investigates what kind of "flash" might be seen by telescopes when astronomers ultimately find gravitational signals from such an event.

Studying gravitational waves will give astrophysicists an unprecedented opportunity to witness the universe's most extreme phenomena, leading to new insights into the fundamental laws of physics, the death of stars, the birth of black holes and, perhaps, the earliest moments of the universe.

A black hole is an object so massive that nothing, not even light, can escape its gravitational grip. Most big galaxies, including our own Milky Way, contain a central black hole weighing millions of times the sun's mass, and when two galaxies collide, their monster black holes settle into a close binary system.

"The black holes orbit each other and lose orbital energy by emitting strong gravitational waves, and this causes their orbits to shrink. The black holes spiral toward each other and eventually merge," said Goddard astrophysicist John Baker.

Close to these titanic, rapidly moving masses, space and time become repeatedly flexed and warped. Just as a disturbance forms ripples on the surface of a pond, drives seismic waves through Earth, or puts the jiggle in a bowl of Jell-O, the cyclic flexing of space-time near binary black holes produces waves of distortion that race across the universe.

While gravitational waves promise to tell astronomers many things about the bodies that created them, they cannot provide one crucial piece of information -- the precise position of the source. So to really understand a merger event, researchers need an accompanying electromagnetic signal -- a flash of light, ranging from radio waves to X-rays -- that will allow telescopes to pinpoint the merger's host galaxy.

Understanding the electromagnetic counterparts that may accompany a merger involves the daunting task of tracking the complex interactions between the black holes, which can be moving at more than half the speed of light in the last few orbits, and the disks of hot, magnetized gas that surround them. Since 2010, numerous studies using simplifying assumptions have found that mergers could produce a burst of light, but no one knew how commonly this occurred or whether the emission would be strong enough to be detectable from Earth.

To explore the problem in greater detail, a team led by Bruno Giacomazzo at the University of Colorado, Boulder, and including Baker developed computer simulations that for the first time show what happens in the magnetized gas (also called a plasma) in the last stages of a black hole merger. Their study was published in the June 10 edition of The Astrophysical Journal Letters.

The simulations follow the complex electrical and magnetic interactions in the ionized gas -- known as magnetohydrodynamics -- within the extreme gravitational environment determined by the equations of Einstein's general relativity, a task requiring the use of advanced numerical codes and fast supercomputers.

Both of the simulations reported in the study were run on the Pleiades supercomputer at NASA's Ames Research Center in Moffett Field, Calif. They follow the black holes over their last three orbits and subsequent merger using models both with and without a magnetic field in the gas disk.

Additional simulations were run on the Ranger and Discover supercomputers, respectively located at the University of Texas, Austin, and the NASA Center for Climate Simulations at Goddard, in order to investigate the effects of different initial conditions, fewer orbits and other variations.

"What's striking in the magnetic simulation is that the disk's initial magnetic field is rapidly intensified by about 100 times, and the merged black hole is surrounded by a hotter, denser, thinner accretion disk than in the unmagnetized case," Giacomazzo explained.

In the turbulent environment near the merging black holes, the magnetic field intensifies as it becomes twisted and compressed. The team suggests that running the simulation for additional orbits would result in even greater amplification.

The most interesting outcome of the magnetic simulation is the development of a funnel-like structure -- a cleared-out zone that extends up out of the accretion disk near the merged black hole. "This is exactly the type of structure needed to drive the particle jets we see from the centers of black-hole-powered active galaxies," Giacomazzo said.

The most important aspect of the study is the brightness of the merger's flash. The team finds that the magnetic model produces beamed emission that is some 10,000 times brighter than those seen in previous studies, which took the simplifying step of ignoring plasma effects in the merging disks.

"We need gravitational waves to confirm that a black hole merger has occurred, but if we can understand the electromagnetic signatures from mergers well enough, perhaps we can search for candidate events even before we have a space-based gravitational wave observatory," Baker said.

Agreement near in Chicago teachers strike, no school Friday

CHICAGO (Reuters) - The Chicago Teachers Union said on Thursday a deal was near to end a four-day strike in the nation's third-largest school district over education reforms sought by Mayor Rahm Emanuel, but a deal will not be reached in time to reopen schools on Friday.

"We are optimistic, but we are still hammering things out. Schools will not open Friday," union president Karen Lewis said in a statement on Thursday.

Lewis said the union House of Delegates will meet at 2 p.m. local time Friday (3 p.m. EDT) to provide an update on the talks. Lewis has said she would need the approval of that body to seal a deal.

The strike by 29,000 public school teachers and support staff, affecting 350,000 elementary and high school students, is the biggest strike in the United States this year.

Lewis, who called Emanuel a "bully" and "liar" before leading teachers on their first strike in 25 years, struck a conciliatory tone after late-night talks on Wednesday.

Barbara Byrd-Bennett, chief education adviser for Chicago Public Schools, told reporters on Thursday: "Given what happened last night, and the progress last night and early this morning with our team ... there's no way - unless we get, like, really nutsy - that we could not have an agreement."

As for schools reopening on Monday, Lewis said: "I'm praying, praying, praying - I'm on my knees - for that, please, yes, I'm hoping for Monday."

COMPROMISE ON TESTING

Lewis said there was progress on the two most vexing issues - using student test scores to evaluate teachers and giving more authority to local principals to hire teachers.

The union is concerned that more than a quarter of its membership could be fired because the teachers work in poor neighborhoods where students perform badly on standardized tests, which Emanuel wants to use to evaluate teachers.

Emanuel's negotiators released a copy of their latest compromise offer teacher evaluations. The mayor's proposal would phase in the new teacher evaluation system over five years and give no more than 20 percent weight to standardized tests. Classroom observations and a survey of students would also be used to evaluate teachers.

Other unresolved issues include the role of principals in hiring teachers and what happens when a school closes and teachers face layoffs.

The union fears Emanuel plans to close scores of schools, putting unionized teachers out of work. In recent years, about 100 public schools have been closed, with officials usually citing low enrollment. At the same time, a similar number of publicly funded, non-union charter schools have opened.

About 52,000 students enrolled at those schools have not been affected by the strike this week.

The strike in Barack Obama's home city has put the U.S. president in a tough spot. Emanuel is a former top aide to Obama and the president is counting on labor unions to drum up support for his re-election on November 6.

Obama's own Education Department has championed some of the reforms Emanuel is seeking, and a win for the ambitious Chicago mayor would add momentum to the national school reform movement.

Both sides agree Chicago schools need fixing. Chicago students consistently perform poorly on standardized math and reading tests. About 60 percent of high school students graduate, compared with 75 percent nationwide and more than 90 percent in some affluent Chicago suburban schools.

The fight does not appear to center on wages, with the school district offering an average 16 percent increase over four years and some benefit improvements. Chicago schools already have a projected $665 million budget gap for the year that began in July, a key factor driving Emanuel's reforms.

More than 80 percent of Chicago public school students qualify for free school lunches because they come from low-income households.

"Teachers feel beaten down throughout the country," said Randi Weingarten, national president of the union including the Chicago teachers. "They feel beaten down because of austerity, because of test- rather than teacher-driven policies, because of a spike in poverty, because of the demand on them to do more with less - and then blame them when that doesn't work out."

"That's what's created all the frustration that you hear on the picket line," she said.

UN: No evidence of new food price crisis

(AP) ? The U.N.'s Food and Agriculture Organization says current prices do not justify talk of a new world food crisis.

Director-General Jose Graziano da Silva says the latest data is "reassuring." Agency officials say the food price index of basic foods remained unchanged in August from July.

FAO official David Hallam told reporters in Rome on Thursday that "there is no strong evidence" to suggest another food price crisis, such as that which sparked unrest in the developing world in 2007-2008.

FAO's latest monthly report found that while there was no overall rise in food prices last month, prices are still high.

While meat and dairy prices rose, sugar prices fell sharply. July's index had reflected soaring prices amid droughts affecting corn and wheat crops.
