For the first time since April 20, no oil is flowing into the Gulf of Mexico, though the halt may be temporary, as integrity testing began on a new sealing cap. The cap was installed on a leaking well in an effort by the BP energy company to contain oil spewing into the Gulf of Mexico. The previous containment cap, which was removed Saturday, had a much looser fit than the new one and allowed oil to escape into the Gulf. It took about three days for the cap to be removed, the site prepared, and the new one to be slowly lowered into position.

The energy company had planned to begin running integrity tests Tuesday to measure the performance of the well under pressure. The tests were delayed a day for further analysis, but clearance to proceed was given Wednesday afternoon, then a leak in a choke line had to be repaired. BP senior vice president Kent Wells announced at his Thursday afternoon briefing that the final valve on the cap assembly started to close at 1:15 PM Thursday and was fully closed at 2:25 PM, finally shutting in the oil flow. If the tests show that the well is strong enough, the sealing cap valves will likely remain closed. If the well cannot be safely closed from the top, the new cap is designed to funnel almost all the oil to ships above while two relief wells are constructed for a permanent fix. After the old cap was removed, oil flowed freely into the waters of the Gulf until the present cap was installed at about 7:00 PM CDT Monday (00:00 UTC Tuesday).

BP has stated that this oil containment system has never been deployed at the current depths, nor has it been tested in the conditions that it will be expected to operate in. During the testing period, which could last anywhere from six to forty-eight hours, all undersea oil containment systems will be temporarily suspended. The company made clear that, even if the tests succeed, this does not mean that oil leakage has permanently ceased.

Doug Suttles, a BP executive, explained that during the test, the well pressure will be carefully monitored. Suttles said at a Monday briefing that the ideal would be for tests to show high pressure around the seal, indicating that no oil is escaping. He also stated that on the other hand, the pressures could be lower than anticipated, leading to the assumption that the well is damaged and is leaking oil and gas into surrounding rock. If this were to happen, keeping the cap shut could further damage the well. The solution for this scenario is to reopen the valves and funnel most, if not all, of the oil to ships above.

Drilling of the first relief well was suspended until completion of the integrity test. Kent Wells explained at his Wednesday morning briefing that the first relief well is now 4 feet from the original well and there is a remote possibility that the pressure test could open a path to the relief well. Drilling of the second relief well has stopped at 16,000 feet so as not to interfere with the first well and to keep routing options open in case the first relief well fails. Even if the pressure tests do succeed and the main well is shut, work on the first relief well will continue until it intercepts the main well. When this occurs, mud and cement will be pumped into the well for a permanent seal. Containment and clean up operations will continue even after the relief wells are finished to deal with oil already released.

The Deepwater Horizon oil spill began on April 20 when the Deepwater Horizon oil rig exploded, killing eleven and marking the start of the worst offshore oil spill in United States history.

NASA’s Cassini orbiter has sent back remarkable images from Saturn, revealing that the planet’s famous rings are far more bumpy than expected.

Astronomers previously thought that the rings were almost completely flat, with changes in height of only a few metres. However analysis of the new images show ridges up to 4 kilometres tall, similar in height to the Rocky Mountains or the Alps.

The images were taken around the planet’s equinox on August 11, when the Sun was directly over Saturn’s equator and caught the rings edge on. A similar equinox occurs today (September 22) on Earth. But whilst equinoxes occur twice a year on Earth, Saturn takes around 29.7 Earth years to orbit the Sun so the events are much rarer.

With the light from the Sun reaching Saturn’s rings at such a low angle, scientists were able to measure the shadows cast by bumps on the rings and discover their surprising height. As Cassini project scientist Bob Pappalardo put it: “It’s like putting on 3-D glasses and seeing the third dimension for the first time. This is among the most important events Cassini has shown us.”

Some of the ring features are known to be caused by Saturn’s moons, but others are harder to explain. “To understand what we are seeing will take more time, but the images and data will help develop a more complete understanding of how old the rings might be and how they are evolving,” said Linda Spilker, Cassini deputy project scientist.

Cassini was launched in 1997, and entered orbit around Saturn in 2004. It is part of the Cassini-Huygens joint mission between NASA, the European Space Agency and the Italian Space Agency.

The new British coalition government has warned local authorities in the United Kingdom not to provide tax breaks to branches of the Church of Scientology. After an investigation by The Guardian newspaper revealed that several local authorities have granted Scientology tax breaks worth over a million pounds, Secretary of State for Communities and Local Government Eric Pickles intervened to urge councils to end the practice.

Pickles noted in a statement that Scientology was not officially recognised in the UK as a religion or a registered charity and was not eligible for tax relief. Pickles commented, “I do not believe the majority of the public would want their own council to be giving special tax breaks to such a controversial organisation.”

The minister’s intervention followed the disclosure by The Guardian that at least four local authorities have given Scientology lucrative tax discounts on branches in their areas. These included:

• The City of London Corporation, which gave an 80% tax exemption worth £1.3 million to the flagship Scientology centre in the City of London. The corporation justified the exemption on the basis that Scientology could be considered to be a charity either for the advancement of religion “or other purposes beneficial to the community”. It said that it feared being sued by the organisation if it discontinued the exemption.

• Westminster City Council granted 80% rates relief to the Scientology Celebrity Centre in the Bayswater district of London. This saved Scientology £165,303 over the past ten years, though as of July 2010 the centre is no longer in use. The council determined that Scientology was a “non-registered charity” that is “beneficial to the community”.

• Birmingham City Council awarded the Church of Scientology Religious Education College an 80% tax discount on the grounds that the property was an educational institution.

• The City of Sunderland gave the Church of Scientology’s branch in the city tax relief worth £30,000 over five years.

Camden London Borough Council refused to disclose whether and how much tax relief had been granted to the Scientology branch in the London Borough of Camden. Other local authorities, including Manchester City Council and Mid Sussex District Council, said that they charged Scientology the full commercial rate.

In response to The Guardian report, Eric Pickles issued a statement saying that Scientology should not receive privileged tax status and did not deserve to do so, “Tolerance and freedom of expression are important British values, but this does not mean that the likes of Church of Scientology deserve favoured tax treatment over and above other business premises. The Church of Scientology is not a registered charity, since the Charity Commission has ruled that it does not provide a public benefit. Nor are its premises a recognised place of worship. Councils may award charitable relief. They should take into consideration the Charity Commission’s rulings when weighing up whether to do so. I do not believe the majority of the public would want their own council to be giving special tax breaks to such a controversial organisation.”

The controversy was the latest in a series of disputes involving Scientology’s tax status in the UK. Scientology is not officially recognised as a religion. The Charity Commission for England and Wales rejected an application in 1999 by Scientology for charitable status, ruling that its activities did not meet the “public benefit” test. However, in 2000 Scientology obtained exemption from Value Added Tax (VAT) on the grounds that its services were educational and non-profitable. It successfully sued HM Revenue and Customs for the return of £8 million in overpaid VAT.

A spokesman for the Church of Scientology told The Guardian, “Scientology is very popular with those who have visited our churches, met with Scientologists and observed or utilised our numerous community activities that effectively address drug abuse, illiteracy, declining moral values, human rights violations, criminality and more. Local council authorities, government bodies in this country and many others, and the European court of human rights have all recognised the religious nature of Scientology or the fact that Scientologists are actively helping those in their communities as a direct reflection of their religious beliefs.”

Birmingham City Council told the local Sunday Mercury newspaper, “We have noted Mr Pickles’ comments and will take them on board.”

Yao Jiaxin, a 21-year-old student at the Xi’an Conservatory of Music, was sentenced to death on Friday. Yao, from Xi’an in China’s Shaanxi province, was convicted of homicide after stabbing a cyclist to death.

On the night of October 20, 2010, Yao ran into 26-year-old cyclist and mother of a two-year-old, Zhang Miao, while driving his car. After he saw her writing down his vehicle’s license plate number following the accident, he feared she would report him, and proceeded to murder her by stabbing her six times. Prior to her murder, Zhang had suffered only minor injuries in the accident, according to police.

On October 23, after being accused of murdering her, Yao went to the local police station with his parents and confessed to the crime. He said he killed Zhang because she had seen his license plate number, and he feared that the “peasant woman would be hard to deal with.”

During a three-hour trial on March 23, 2011, Yao’s lawyer pleaded for a lenient sentence, saying it was a “crime of passion.” Yao tearfully described how he had been forced to play the piano, leading him to thoughts of suicide. But prosecutors and judges said Yao did not deserve leniency, as he had not attempted to help the woman after the accident but instead murdered her.

Public passions were raised and some thought Yao would get off through the influence of his family. The case triggered a public debate over the death penalty.

“The motive is extremely despicable … the measures are extremely cruel … and the consequence is extremely serious,” said the court in its judgment.

The nuclear reactor at Chalk River, Ontario in Canada was shut down on Thursday, May 14 by the Atomic Energy of Canada Limited (AECL) due to a leak of heavy water. Government officials say that by Saturday the demand for medical isotopes will no longer be met, due to the shortage caused by the closure.

Medical isotopes are used in diagnostic procedures for cancer, heart disease and other medical conditions. When radioactive isotopes are injected into the body, radiologists can view higher radiation via medical imaging, enabling them to make a more accurate diagnosis.

Estimates suggest that the reactor will be shut down for approximately one month for repairs. The Chalk River Laboratories produce 33% of the international supply of medical isotopes.

Lisa Raitt, Natural Resources Minister said, “A secure supply of medical isotopes is not only an issue for Canada, it is an international issue that is being addressed co-operatively by all isotope-producing countries.”

“It may mean that if you have an elective study booked … that patient is going to be deferred and will have to wait until the situation is resolved. I’m reasonably confident that for most patients, if they’re having an acute problem, that problem is going to be dealt with – and the greater the acuity, the more likelihood it’s going to be dealt with quickly and expeditiously,” said Dr. Karen Gulenchyn, a nuclear medicine expert.

“The government of Canada is engaging international isotope producers as well as companies such as MDS Nordion, Lantheus, and Covidien, who all play key roles in securing medical isotope supply for North America,” said Raitt and Health Minister Leona Aglukkaq.

In December 2007, the 52-year-old reactor was shut down and the Canadian House of Common stepped in to restart the reactor.

Two buildings have been damaged in a bombing in Athens, Greece on Thursday. The target was a building owned by an agency that manages state real estate.

Nobody was injured in the blast, but the building’s entrance was damaged. A nearby store and a parked car also sustained damage. The homemade device, which consisted of explosives placed inside a plastic bag and tied to a pole close to the target, damaged the Hellenic Public Real Estate Corporation building.

The area was cordoned off by police after the explosion, which occurred at 9:30 p.m. local time yesterday. Bomb disposal experts checked the area following the explosion, while anti-terrorism officers began their investigation. The building is about 250 yards from the Athens police headquarters, and is also close to the Supreme Court.

No claim of responsibility has yet been made, but the Greek conservative government has been attempting to control left-wing terrorism in recent months. One group, the Revolutionary Struggle, was responsible for a failed car bombing against an Athens Citibank office on February 28, and also bombed a Citibank branch in the city on March 9. Greece has been receiving advice from police in London after the increase in terrorist activity and rioting last year throughout the nation.
