Egypt says citizens free to join fight in Syria

(AP) ? A senior official in Egypt's presidency said Thursday that Egyptians are free to join the fight in Syria and will not be prosecuted upon return amid increasingly public calls by leading clerics for Sunni Muslims to back the rebels there with firepower.

In a response to an Associated Press question about the government's stance on citizens going to fight alongside Syrian rebels, Khaled al-Qazzaz said that "the right of travel or freedom of travel is open for all Egyptians," adding that the state was taking no measures against anyone who goes to fight in Syria. He underlined that Egypt seeks a political solution to Syria's conflict and warned of the danger of it becoming a "regional war."

The comments by al-Qazzaz, a foreign affairs adviser to Islamist President Mohammed Morsi, come at a time when clerics have stepped up calls for Sunnis in the Arab world to go to Syria to fight the regime in response to the Lebanese Shiite guerrilla group Hezbollah's overt intervention backing the Syrian military against rebels.

The calls have hiked fears that Syria's civil war will slide deeper into sectarian conflict and that foreign jihadis will take an even greater role in the rebellion. The presence of non-Syrian extremists, some with al-Qaida links, among the rebels has made the U.S. and its allies reluctant to send weapons to the rebellion.

Speaking in a meeting with foreign journalists, al-Qazzaz dismissed worries that Egyptians who fight in Syria could return home as hardened jihadis, even as extremists in the northern Sinai Peninsula continue to wage assassinations and attacks against the police and military there.

"We don't consider them a threat," al-Qazzaz said. "We have a controllable situation in Sinai ... We do not have a situation of returning jihadists."

He said that after the 2011 uprising that toppled longtime autocrat and U.S. ally Hosni Mubarak, Egypt no longer takes part in the CIA's "extraordinary renditions" program, in which Mubarak's government helped detain suspected Islamic militants as part of the U.S.'s war on terror. The program raised allegations of illegal kidnappings and torture of suspects.

"We are no longer a center for rendition, or punishing Egyptians for what they do in other countries," he said.

It is not known how many Egyptians have gone to fight in Syria ? and al-Qazzaz said he did not have figures. But organizations from Egypt's ultraconservative Salafi movement are believed to help organize movements for Egyptians who want to join the fight. Islamist websites have reported that up to several dozen Egyptians have been killed while fighting in Syria the past two years, though the number has not been independently confirmed.

The conflict, now in its third year, has killed nearly 93,000 people, according to new figures released by the United Nations.

Earlier this month, influential Egyptian cleric Yusuf al-Qaradawi, who has close ties to the Muslim Brotherhood, urged Sunnis everywhere to join the fight against Syrian President Bashar Assad.

"Everyone who has the ability and has training to kill ... is required to go," said al-Qaradawi, a popular television cleric who is based in Qatar. "We cannot ask our brothers to be killed while we watch."

A group of Muslim clerics, including al-Qaradawi, met in Cairo on Thursday and said it was a religious duty to back the rebels through whatever means possible.

The meeting underlined "the duty of jihad to support our brothers in Syria, with spirit, money and weapons, and all forms of jihad aimed at rescuing the Syrian people from the crimes and killings by the sectarian regime ... everyone according to his ability," hard-line Egyptian cleric Mohammed Hassan said, reading a statement from the group. He said Iran and Hezbollah's support for Assad "against our people in Syria is considered a declaration of war on Muslims in general."

A delegation of clerics then met with Morsi at the presidential palace on Thursday. The Egyptian president plans to attend a large rally in support of the Syrian opposition at Cairo's stadium on Saturday, which has been organized by the senior clerics.

The Muslim Brotherhood, from which Morsi hails, is also calling on people to aid Syrians.

"We call on Arab and Islamic people to stand by their Syrian brothers ? those who remain in the country or were forced to flee to other neighboring countries. We should not be unjust, surrender them or let them down. Religion, manhood and chivalry require that we be by their side and support them financially and morally," the group's statement said.

Among the most well-known Egyptians to have died in Syria is a 27 year-old named Yusif Mehrez, who was killed in the western city of Aleppo. Local media carried pictures of him kissing his mother's hand at the airport before flying to Syria to help fight alongside the rebels. A number of videos have also appeared online, purporting to show Egyptian men fighting in Syria. In one video an Egyptian man carrying a rocket-propelled grenade swung over his shoulder is shot by Assad's soldiers during a battle.

The fighting in Syria has turned increasingly sectarian and the largely Sunni Muslim rebels appear to be outgunned by Assad's military, which is backed by Shiite Iran and Russia. It has escalated from a local uprising into a civil war. The rebels, backed by Sunni states Saudi Arabia, Qatar and Turkey, are fighting against a regime that relies on support from Assad's Alawite community, as well as Shiites aided by Iran and Hezbollah.

International efforts to forge a round of peace talks have stalled, including an attempt by Egypt's president to find a solution to the crisis through a so-called Islamic Quartet that includes Egypt, Turkey, Iran and Saudi Arabia.

Al-Qazzaz said that Egypt is looking for a regional solution backed by the international community, and that a political solution is needed. He described what is happening there as "an act against humanity."

"The more we fuel this conflict with weaponry and soldiers, it turns into a regional war," he said.

The hard-line Salafi Nour Party also says Egyptians should be free to help Syrians in combat.

"Egypt, after the revolution, cannot stop anyone doing that because they are not going to upend the legitimacy of a government or carry out terrorist attacks. This is a revolution," said Amr el-Mekky, assistant to the party's chairperson for foreign affairs. But he underlined that any fighters who return home must respect Egyptian law.

Magnetic fingerprints of superfluid helium-3

May 21, 2013 ? Superconducting sensors have allowed for highly sensitive measurements of the nuclear magnetic resonance of thin helium-3 layers.

With their SQUIDs, low-temperature specialists of the Physikalisch-Technische Bundesanstalt (PTB) have made it possible for the magnetic moments of atoms of the rare isotope 3He (helium-3) to be measured with extreme sensitivity. With the aid of these sensors, highly sensitive nuclear resonance spectrometers were developed which have now provided deep insights into the state of matter at extremely low temperatures. In concrete terms, the international research group from London, Ithaca (USA), and PTB's Berlin Institute confined the helium-3 as extremely thin -- quasi two-dimensional -- liquid film. With their extremely precise measuring instruments, they were then able to measure the properties of the superfluid more exactly than ever before. In this way, they have made an important step towards understanding the unique quantum liquid helium-3 and its superfluid properties.

The results have been published in the current edition of the journal Science.

The superconducting quantum interference devices used are the most precise measuring instruments available to detect extremely weak magnetic signals. They are already used routinely, e.g. in biomedical measurements, to examine the magnetic fields of the human brain or heart. What is even more topical is their use together with other superconducting detectors to measure radiation with extreme sensitivity or to detect even single photons (see also Nature 497, 227-230, 9 May 2013). And the third application is that of the current study: Since the mid-90s, PTB's SQUIDs have played a central role in the cooperation between scientists of the Royal Holloway University of London and PTB's cryogenic sensor group. This has led to particularly sensitive nuclear resonance spectrometers for experiments at ultra-low temperatures in order to gain ever deeper insights into the state of matter at these extreme conditions. Among other things, the scientists aim at investigating helium-3 -- a unique quantum liquid.

Helium-3 is the much rarer sister of helium-4 which is needed, e.g., to bring the coils of a magnetic resonance tomograph to working temperature. For this purpose, they must become superconducting, which is only possible with the temperature of the liquid helium-4 being -269 ?C (4 K), i.e. approximately 4 ?C above absolute zero. If you want to get even closer towards absolute zero, you will need helium-3. Its natural abundance is 10,000 times lower than helium-4 and, therefore, helium-3 is synthesized in nuclear reactors. Only by means of a mixture of the two helium isotopes and a sophisticated magnetic cooling technique can matter be cooled down to a few millionths of a kelvin above absolute zero and experiments can then be carried out with these materials.

The scientists have a great interest in getting to know their unique cooling liquid as well as possible. Helium-4 and helium-3 are fascinating substances as they become superfluid at very low temperatures and can thus flow without frictional resistance. However, the superfluids of the two isotopes vary significantly from a quantum-mechanical point of view, as helium-4 atoms are bosons, whereas helium-3 atoms are fermions. In the latter, superfluidity develops through the formation of pairs of helium-3 atoms via magnetic interaction. These magnetic properties thus decisively determine the properties of the superfluid.

Physicists of the low-temperature laboratory of the Royal Holloway University of London in cooperation with Cornell University of Ithaca, USA are dealing with the detailed investigation of these superfluids under extreme conditions. It gets really exciting for the physicists if you confine the liquid under pressure at extremely low temperatures below one thousandth of a degree above absolute zero in thin cavities which are only several hundred nanometres thick (i.e. 50 to 100 times thinner than a human hair). Then the behaviour of the helium-3 atoms, or of the pairs which make up the superfluid, will be strongly influenced by this movement restriction in one dimension. Especially the surface scattering of the particles in the cavity has a great influence on their properties, similar to a football which -- shot at a smooth or rough wall -- will bounce off more or less predictably. The conditions in this ultracold liquid lamella -- the physicists hope -- will enable the detection and investigation of excitations that behave like so-called Majorana fermions (particles being their own antiparticle).

The challenging problem for these kinds of experiments is the measurement of the properties of the extremely thin helium-3 liquid lamella. As the interactions of the magnetic moments of the helium-3 atomic nuclei play a decisive role, so-called nuclear magnetic resonance spectroscopy -- a measurement technique similar to magnetic resonance imaging (MRI) for medical diagnostics -- is applied. Magnetic resonance spectra are characteristic fingerprints of the state of the helium-3 atoms from which information about the properties of the liquid can be obtained. It is just that magnetic resonance spectroscopy of helium-3 deals with much weaker signals and extreme temperature ranges than medical MRI. Extremely sensitive magnetic field sensors which operate reliably at ultra-low temperatures are needed. Here, the SQUIDs, which have been developed by PTB's physicists and engineers for more than two decades, came into play. PTB's SQUID sensor technology was implemented at the Royal Holloway University of London into the experimental set-up which was finally used to measure the properties of helium-3 liquid lamellas. The results achieved are an important step to understanding this unique quantum liquid. The groups of scientists are already working on improved sensor arrangements which, in future, will be used to examine helium-3 liquid lamellas with spatial resolution. The work was one of a number of research activities funded by the EU within the framework of the "European Microkelvin Collaboration."

Anabolic steroids may affect future mental health

There is a link between use of anabolic-androgenic steroids and reduced mental health later in life. This is the main conclusion of a new study on elite male strength athletes that researchers from the University of Gothenburg recently published in the British Journal of Sports Medicine. Twenty per cent of the subjects in the study admitted steroid use.

The study is published by CERA, which is the University of Gothenburg's centre for education and research on addiction. Together with colleagues from Sahlgrenska University Hospital, they found a connection between abuse of anabolic-androgenic steroids (AAS) and mental health problems many years later.

The study included almost 700 former Swedish wrestlers, weightlifters, powerlifters and throwers who competed at the elite level sometime between 1960 and 1979. Twenty per cent of them admitted using steroids during their active careers. The purpose of the study was to look for links between AAS use and mental problems.

'We found a clear link. AAS users were more likely to have been treated for depression, concentration problems and aggressive behaviour,' says Claudia Fahlke, director at CERA.

The researchers also found that AAS users were more likely to have abused other illicit drugs and alcohol. However, it remains unclear whether the steroid use actually caused the mental health problems or the mental health problems rather caused the steroid use.

'What we were able to show, though, is that psychiatric symptoms and use of steroids and other drugs tend to reinforce each other in a vicious cycle. This suggests that the anti-doping efforts remain very important, both in and outside of sports,' says Fahlke.

(AP) ? Authorities believe the driver who plowed into dozens of hikers marching in a Virginia mountain town parade suffered from a medical condition and did not cause the crash intentionally, an emergency official said Sunday.

Officials did not have a formal confirmation or any specifics on the condition, but based on the accounts of authorities and witnesses on the scene, they are confident the issue was medical, according to Pokey Harris, Washington County's director of emergency management. "There is no reason to believe this was intentional," she said.

In what witnesses called a frantic scene at the parade, about 50 to 60 people suffered injuries ranging from critical to superficial Saturday. No fatalities were reported. Three of the worst injured were flown by helicopter to area hospitals.

Two people were kept at hospitals overnight, but their injuries were not critical as of Sunday, Harris said. "For the most part, everyone was treated and released," she said.

The crash happened around 2:10 p.m. Saturday during the Hikers Parade at the Trail Days festival, an annual celebration of the Appalachian Trail in Damascus, near the Tennessee state line about a half-hour drive east of Bristol.

Damascus Police Chief Bill Nunley didn't release the driver's name or age but said he was participating in the parade and he had traversed the Appalachian Trail in the past. Several witnesses described him as an elderly man.

Nunley said the man's 1997 Cadillac was one of the last vehicles in the parade and the driver might have suffered an unspecified medical problem when his car accelerated to about 25 mph and struck the crowd on a two-lane bridge along the town's main road. The driver was among those taken to hospitals.

"It is under investigation, and charges may be placed," Nunley said Saturday.

On Sunday, festival events were continuing as scheduled, Harris said. Mayor Jack McCrady had encouraged people to attend the final day.

"In 27 years of this, we've never had anything of this magnitude, and is it our job to make sure it doesn't happen again," he said.

Harris said that the incident left a "sad heart and black cloud" over the event and that people were proceeding with "heightened awareness." But she emphasized the crash was an accident and said no additional security measures were taken.

On Saturday, Rudolph "Chip" Cenci, 64, of Minoa, N.Y., told The News-Item newspaper in Shamokin, Pa., that he heard people yelling "get out of the way" and turned around to find the car was about to hit him. He jumped onto the hood and held onto the gap at the base of the windshield near the wipers. He said the driver had a blank stare on his face.

"I bet you that man never realized someone was on his hood," Cenci said.

Cenci said he had a bump on his knee but was otherwise OK. He added that his wife, Susan, 63, narrowly missed being hit.

Amanda Puckett, who was watching the parade with her children, ran to the car, where she and others lifted the car off those pinned underneath.

"Everybody just threw our hands up on the car and we just lifted the car up," she said.

Keith Neumann, a hiker from South Carolina, said he was part of the group that scrambled around the car. They pushed the car backward to free a woman trapped underneath and lifted it off the ground to make sure no one else was trapped.

"There's no single heroes," he said. "We're talking about a group effort of everybody jumping in."

Wyo. student who threatened to rape self on Facebook was convicted of assault

The 28-year-old University of Wyoming student who allegedly threatened herself with rape in a Facebook hoax in April was convicted of aggravated assault in 2005 after she brandished a gun at an employer who fired her.

Meg Lanker-Simons, now a newly-minted UW graduate, was charged with interference with a police investigation after she allegedly posted on an anonymous Facebook forum that she wanted to engage in angry sexual intercourse ? with someone named ?Meg Lanker Simons.?

The posting on UW Crushes read:

?I want to hatefuck Meg Lanker Simons so hard. That chick runs her liberal mouth all the time and doesn?t care who knows it. I think its so hot and makes me angry. One night with me and shes gonna be a good Republican bitch.?

It turns out that the April 24 incident isn?t the strident leftist?s first rodeo in Wyoming?s criminal system. As the Laramie Boomerang reports, Lanker-Simons had an aggravated assault conviction in 2005 as the result of a bizarre gun-brandishing incident.

After Lanker-Simons was fired from a radio station in the fall of 2005, she returned and pulled a Glock 22 .40 caliber handgun from her purse. She waved the semi-automatic pistol around. She pointed it at the man who sacked her. He testified that he was ?in fear for his life,? notes the Boomerang.

The radio station was evacuated. Police caught Lanker-Simons as she tried to flee the scene in her vehicle. They held her at gunpoint.

In July 2006, Lanker-Simons ? then known as Meghan Michelena ? was sentenced to six years of probation. Her term of probation was subject to a number of conditions. She had to undergo counseling, complete community service, pay fines and apologize to her victims. She was also prevented from owning any guns.

The alleged Facebook hoax brought national attention to the Cowboy State?s flagship college. Initially, the administration stood firmly behind Lanker-Simons. ?No student should have to deal with such threatening language,? said one sternly-worded official statement. A school official also denounced ?rape culture,? according to KOWB.

Concerned fellow feminists also threw a rally for Lanker-Simons ? complete with all manner of signs condemning rape threats ? before police concluded that Lanker-Simons herself was behind the threats.

This month, Lanker-Simons participated in the University of Wyoming?s commencement ceremonies despite the charges against her. She graduated with a bachelor?s degree in psychology.

Lanker-Simons is also a blogger and a local radio host.

In 2010, Lanker-Simons and Bill Ayers sued the University of Wyoming after school officials decided to cancel a speech by Ayers, a former Weather Underground radical and mentor to President Obama. Also in 2010, her husband, Andrew Simons, ran a failed Democratic campaign for Wyoming secretary of state.

According to the Boomerang, the interference charge is a misdemeanor punishable by a prison sentence up to a year and a fine up to $1,000.
