The Volkswagen emissions scandal continued yesterday with the company announcing 800,000 mainly diesel vehicles may also be affected by carbon dioxide emissions problems.

The company stated “the safety of the vehicles is in no way compromised”. They estimated potentially this could cost them €2bn on top of the €6.7bn set aside to pay for the cost of correcting 11 million cars affected when the scandal broke, in addition to fines by regulators.

This follows Monday’s revelation that the emissions scandal has affected up to 10,000 vehicles sold in the USA by brands in the Volkswagen group, although the company refutes the allegation. The United States Environmental Protection Agency (EPA), the regulatory body which has been investigating Volkswagen, claims the company fitted a number of recent Audi, Porsche, and Volkswagen models with technology that initiates secret components during emission tests to ensure the results are favourable.

The scandal began with damaging revelations that the car manufacturer has been using illegal software to enable diesel cars to cheat on mandatory emissions tests. This lead to a public apology on September 20 by then-chief executive Martin Winterkorn and the promise of an outside inquiry. He then resigned on September 23, and was replaced by Matthias Müller. The new allegation about Porsche is of particular concern for Müller, because he had previously been in charge of Porsche.

The company is expected to foot the bill for the recall of close to 500,000 VW and Audi cars affected at the time. There is also the possibility of Volkswagen having to pay federal fines of up to US$18 billion dollars because the US Clean Air Act sets a maximum fine of US$37,500 for each vehicle that contravenes the requirements of the Act.

An investigation into alleged breaches of environmental law was originally initiated on the advice of the International Council on Clean Transportation, a European non-governmental organisation. The EPA requested tests be carried out by West Virginia University, where the secret software was discovered.

The software, known as a “defeat device”, enabled cars to identify when they were being tested and to switch on the emission control system. The devices may have been adding urea to the car exhaust because that would reduce the amount of nitrogen dioxide. The car would release a fraction of the nitrogen oxide compared to when they were being driven normally. Emissions of nitrogen oxide contribute to smog and are thought to have caused a rise in respiratory illnesses like asthma.

Indian nuclear scientist Homi Sethna has died at the age 86. His death was announced by Homi Mehta, a long time associate of Sethna. The cause of death was announced as lung fibrosis.

During his career Sethna held several posts including director of the Bhabha Atomic Research Centre and chairman of the Atomic Energy Commission. During his time with the AEC Sethna presided over India’s nuclear experiment at Pokhran in 1974.

K. Sankaranarayanan, governor of Maharashtra, said in a condolence message “Dr. Homi Sethna was one of India’s pioneering nuclear scientists, who had played a crucial role in the successful conduct of India’s first peaceful nuclear test in 1974. Even after his retirement, he held many important positions and continued to contribute to the task of nation building. I pay my respects to the memory of Dr. Sethna… and convey my heartfelt condolences to his family members.”

A Norwegian University of Science and Technology study released Thursday found electric vehicles have a potential for higher eco-toxicity and greenhouse impact than conventional cars. The study includes an examination of the electric car’s life cycle as a whole rather than a study of the electric car’s environmental impact during the use phase.

The researchers conducted a comparison of the environmental impact of electric cars in view of different ratios of green-to-fuel electricity energy sources. In the case of mostly coal- or oil-based electricity supply, electric cars are disadvantageous compared to classic diesel cars with the greenhouse effect impact being up to two times larger.

The researchers found that in Europe, electric cars pose a “10% to 24% decrease in global warming potential (GWP) relative to conventional diesel or gasoline vehicles”.

The researchers suggest to improve eco-friendliness of electric vehicles by “reducing vehicle production supply chain impacts and promoting clean electricity sources in decision making regarding electricity infrastructure” and using the electric cars for a longer time, so that the use phase plays a more important role in the electric vehicle life cycle.

On March 21, 2006, Sun Microsystems released the source code for its newest processor, the UltraSPARC T1. The UltraSPARC T1 is available with four, six or eight cores, each able to work on four threads at a time. The concept is similar to that of the Intel Pentium EE which uses two cores with two threads.

A multicore processor is like having many CPUs on the one chip. Multiple threads allow each core to work on a number of tasks concurrently on a single core. This is particularly useful in a server environment where the UltraSPAC T1 was designed to be used.

Sun call the open source version of their processor the OpenSPARC T1 and have made the source code (in Verilog format) and specifications available on the OpenSPARC T1 website under the General Public License, the same license under which most distributions of Linux are released.

Industry observers say that the move is triggered by the SPARC architecture’s shrinking market share to the likes of IBM’s POWER architecture and x86 based chips from Intel and AMD.

Open Source Hardware has been gaining momentum since 2002, when Kofi Annan issued a challenge to technology companies. Despite Sun’s OpenSPARC T1 not being the first open source processor in the world, it is the first time that the design for a proprietary design processor has been released to the open source community.

The Bush administration officially notified Congress Monday of its intention to sell sophisticated precision-guided bombs to Saudi Arabia. The action, coinciding with President Bush’s visit to Saudi Arabia, is part of a broader U.S. effort to bolster Gulf allies in the face of a more assertive Iran. VOA’s David Gollust reports from the State Department.

The Bush administration has already briefed Congress on its arms sales plans for Saudi Arabia. Monday’s announcement sets in motion a 30-day period in which the House and Senate can block the plan with a joint resolution – an action that appears highly unlikely.

Under the proposed deal, worth more than $120 million, the United States would provide Saudi Arabia with 900 kits and associated equipment to convert conventional gravity bombs into GPS-guided smart-bombs, known as JDAMs.

The weapons are a mainstay of the U.S. military arsenal and their accuracy would vastly enhance the capability of the Saudi Air Force, which has top-of-the-line U.S.-made fighter-bomber aircraft.

The sale is part of a broader $20-billion arms package for Saudi Arabia and other Gulf states announced by Secretary of State Condoleezza Rice and Defense Secretary Robert Gates last August on a mission to the Gulf, aimed at shoring up U.S. allies concerned about Iranian influence in the region.

Several elements of the broader package including sales of Patriot anti-missile systems to Kuwait and the United Arab Emirates, and upgrades for Saudi Arabia’s AWACS airborne command and control planes, have already gotten congressional assent. Officials here say they also expect the Saudi J-DAMS sale to proceed despite concerns expressed by some congressional supporters of Israel.

At the time the Gulf weapons sales package was announced last year, the Bush administration also committed to a 10-year, $30-billion arms package for Israel, representing a 25 per cent increase in annual U.S. arms aid to that country.

Briefing reporters, State Department Spokesman Sean McCormack said the administration has assured Congress it would do nothing to upset Israel’s military edge over potential enemies in the region.

“We’ve spent a lot of time assuring that we abide by our commitments to a qualitative military edge for Israel,” said Sean McCormack. “This is something that President Reagan first talked about and it’s been reiterated and reconfirmed by each successive president after that. We’re committed to maintaining that qualitative military edge for Israel.”

Israel itself has not protested the pending sale. Israeli officials have said they anticipate being provided with a new-generation U.S. smart bomb more capable than J-DAMS, which have been in service for more than a decade.

A spokesman for House Foreign Affairs Committee Chairman Tom Lantos, a prominent advocate for Israel in Congress, said he does not intend to push a resolution of disapproval.

However one House member, New York Democrat Anthony Weiner, said he would introduce such a measure and already has more than 30 co-sponsors.

Critics of the package have faulted Saudi Arabia’s record in combating terrorism and advancing political reform. Under questioning here, Spokesman McCormack said the Saudi government has made “quantum leaps” in action against terrorist cells and financing in recent years and has begun the process of reform, though not necessarily at a pace that would please some critics.

Two-thirds majorities of the members in both houses would be required to block the sale and officials here say chances for that appear nil.

Student protests against the French Prime Minister Dominique de Villepin job reform plan to give employers the right to dismiss young employees within the initial two years of their employment turned increasingly violent over the last two weeks.

The controversial program called the CPE, “First Job Contract”, is to encourage employers to hire people under the age of 26. The French government claims that this process is necessary to reduce the unemployment rates of young people, which is pegged as high as 23% (this rate is the quotient of the number of people under 26 deemed to seek employment over the total of those employed and deemed to seek employment, which excludes the large proportion of students in that population). However, student protestors and trade unions say that the legislation infringes on workers’ rights, and opinion polls show that some two-thirds of the population want the CPE either modified or dropped altogether.

The CPE allows employers to hire people age 26 and younger on a contract for up to two years which may be terminated at any time without explanation. While supporters of the law say that it will make younger people more attractive for employers, opponents say it makes it harder for young people to find long-term employment as there is no incentive for employers to offer any other form of contract.

Labour unions and student organisers are calling for a national strike on Tuesday, the fifth strike in the past two weeks.

The French labor laws are claimed to be among those protecting employees the most in Europe; they prevent employers from trimming their workforces without paying substantial severance packages. Prime Minister de Villepin’s claims to intend to reduce youth unemployment by focusing on attracting modern industries relying on higher employee turnover and more flexible employment arrangements.

The current program is similar to the CNE ordinance the Prime Minister issued last summer for small businesses in France.

CPE was adopted under an exceptional “fast-track” procedure allowing the executive to pass legislation through Parliament without Parliament having to approve it, known as “49-3” following from the number of the relevant article in the French Constitution. This procedure is normally reserved for important but controversial texts considered a crucial and urgent element of the policies of the Prime Minister. Once 49-3 is declared, the law is considered adopted by Parliament unless the National Assembly votes a motion of censure, which terminates the Prime Minister and his cabinet’s term. Following standard practice when 49-3 is used, a motion of censure was proposed by the opposition, then voted down by the Assembly (in which the ruling UMP party has a majority).

In findings published Sunday in Environmental International, a team from Britain’s University of Exeter reports that surfers and bodyboarders are roughly three times as likely to house antibiotic-resistant Escherichia coli and other bacteria that could easily become resistant, than other people who recreate in the coastal waters of the United Kingdom.

The epidemiological study was nicknamed the “Beach Bum Survey”. The project was performed on 143 regular surfers, body surfers and bodyboarders from around the United Kingdom. Each surfgoing participant was asked to recruit a non-surfing friend of the same sex and approximate age and who lived in the same part of the country to serve as a control, which resulted in a control group of 130.

All participants mailed in rectal swabs, and the researchers cultured the E. coli from those samples with a common antibiotic called cefotaxime. The antibiotic failed to kill the bacteria in about 9% (13 out of 143) of surfer and bodyboarder samples and 3% of the samples from the control group (4 out of 130). A deeper look into the genomes of the specific strains of bacteria found in the study volunteers showed that bacteria from surfers were four times as likely to possess genes that can be transferred from one bacterial strain to another, which can help antibiotic-susceptible bacteria become resistant. The study also involved examination of water samples from the coasts of England and Wales to estimate the risk of surfers and other beachgoers ingesting E. coli.

E. coli is a regular resident in the guts of humans and other animals. Most strains are harmless but others can cause serious disease. Like other bacteria, E. coli can undergo horizontal gene transfer, swapping genes from one bacterium to another. This can give the altered strain the ability to cause disease, survive in the presence of antibiotics or both.

Although the researchers expressed concern surfers might spread dangerous bacteria, Dr. Will Gaze, the University of Exeter Medical School professional who supervised the project, urged people not to avoid the beach: “We are not seeking to discourage people from spending time in the sea, an activity which has a lot of benefits in terms of exercise, well-being and connecting with nature”, he said. “It is important that people understand the risks involved so that they can make informed decisions about their bathing and sporting habits. We now hope that our results will help policy-makers, beach managers, and water companies to make evidence-based decisions to improve water quality even further for the benefit of public health.”

David Smith, science and policy officer of Surfers Against Sewage, which helped organise the volunteers, agreed the study was not meant to discourage surfing: “Water quality in the UK has improved vastly in the past 30 years and is some of the cleanest in Europe. Recognising coastal waters as a pathway for antibiotic resistance can allow policy makers to make changes to protect water users and the wider public from the threat of antibiotic resistance.”

One of the principal findings of this work was that existing methods may have been underestimating the prevalence of these bacteria in seawater. Previous studies have shown that even designated swimming beaches can be affected by runoff from farms or even sewage, and surfers swallow roughly ten times as much seawater as swimmers. Professor Colin Gardner of the charity Antibiotic Research UK says, these forms of runoff can have even higher concentrations of antibiotics than patients undergoing antibiotic treatment. “Research into new medicines to replace our archaic antibiotics has stagnated and unless new treatments are found, this could be potentially devastating for human health”, he warns.

The World Health Organization has reported that because so many kinds of bacteria are gaining resistance to common medicines, conditions such as pneumonia and gonnorhea may become more difficult to treat and have higher rates of sickness and death. Doctors often prescribe preventative antibiotics to patients undergoing surgery or radiation therapy, and this may also be impacted. Professor Sally Davies, England’s chief medical officer, has described a “post-antibiotic apocalypse” scenario

The European Regional Development Fund and Natural Environment Research Council provided funding for the study.
