Google has started phasing out support for Microsoft’s Internet Explorer 6 (IE6), following a hacking attempt that exploited an IE6 vulnerability, despite the flaw being fixed promptly.

From March 1 on, some services, such as Google Docs, will not work “properly” when accessed from the browser. Google recommends that both firms and end-users upgrade “as soon as possible”. Google now only officially supports Internet Explorer 7+, Firefox 3+, Chrome 4+ and Safari 3+.

Hackers exploited a weak spot in Internet Explorer to find the contents of Gmail accounts of human rights activists in China. Following this, both the French and German governments advised that users should switch to a different browser until the flaw had been plugged.

Microsoft issued a patch quickly after the revelations, pushing out a scheduled update just under three weeks earlier than they had scheduled. The software giant normally issues updates once a month, but the high press coverage led it to run an unscheduled update. However, Microsoft admitted that they knew about the problem “since early September”, and were planning to patch it in February, leaving the hole open for five months.

Rajen Sheth, the Senior Product Manager for Google Apps, said in a blog post that the web had “evolved in the last ten years, from simple text pages to rich, interactive applications including video and voice”, and that “very old browsers cannot run many […] new features”.

20% of users still use the browser, released in August 2001 in order to complement the then-new Windows XP operating system, including many governments. Microsoft will support the browser until 2014, although the browser has attracted strong criticism among people in the web industry.

The bad publicity garnered from the attacks has allowed rivals, such as Mozilla Firefox and Google’s own browser, Chrome, to gain market share, allowing the open-source Firefox, of which a new version (3.6) has just been released, to claw a 40% share, close to overtaking Microsoft’s 45%.

Last July, Google also dropped IE6 support from the popular video sharing site, YouTube. Popular sites, such as Facebook and Digg, have also dropped support. IE6 does not support several key technologies, making compatible web-design hard to do. For example, it does not render partial transparency in png images, and many site designers must work around the fact that Internet Explorer 6 does not support many important parts of the cascading style sheets (CSS) family of standards, which is how the majority of websites are designed.

Two 16-year-old British girls were arrested in Accra, Ghana earlier this month for apparently attempting to smuggle £300,000 worth of cocaine in laptop bags.

Yasemin Vatansever, of Cypriot descent and Yatunde Diya of Nigerian descent were arrested as they attempted to board a British Airways flight from the Kotoka International Airport on July 2, 2007. The arrest was by the Ghanaian Narcotic Control Board. They were alleged to be carrying 6.5 kg of drugs. They are currently in Ghana police custody and have been visited by British High Commission staff.

The girls who are both students from Islington, north London, had left home after informing their families they were making a school trip to France. They are expected to be charged with “possessing narcotic drugs and attempting to export drugs”, for which they could be jailed for up to ten years if found guilty.

The arrest is part of the Operation Westbridge project set up in November 2006 as a collaboration between the Ghanaian Narcotic Control Board and HM Revenue and Customs of the UK. It is to curb the influx of drugs into Europe and the UK through West Africa which is now being used as a transit point from South America. The project involves the provision of technical and operational expertise to the Ghanaian teams and training in the use of specialist scanning equipment. Ghana is the first country in Africa to introduce such equipment.

The Independent Monitoring Commission has reported that the Provisional Irish Republican Army has undergone major changes within their military structure and shows that the IRA Army Council wants to put its military campaign behind it. The Commission consists of John Alderdice, a former Alliance Party leader; Joe Brosnan, former Secretary General of the Department of Justice, Republic of Ireland; John Grieve, former Deputy Assistant Commissioner of the Metropolitan Police and former head of the Metropolitan Police Anti-Terror Branch; and Dick Kerr, former Deputy Director of Central Intelligence Agency.

The report states the IRA no longer has the capacity to mount a military campaign anymore or return to one. The units that have been shut down were responsible for weapons-making, arms smuggling and training. The IRA decommissioned their arms last year.

The report also mentions that the IRA has also put its criminality beyond use and is “clamping down” on criminals within the organization, said Lord Alderdice, as he presented the report. He also added, “That doesn’t mean that criminal activity by all members has stopped but the leadership has made public statements and internal directions, investigated incidents of breach of the policy, even expelled some members and has emphasised the importance of ensuring that business affairs are conducted in a legitimate way.”

Finally, the report added that there is not enough evidence or intelligence to identify who killed Denis Donaldson, a British spy who infiltrated the IRA and Sinn Fein, before revealing his status as a spy.

However, the report added that splinter groups like the Real IRA (RIRA) and Continuity IRA (CIRA) are still threats and are still continuing their activity. The Real IRA was the group behind the deadly 1998 Omagh bombing. The Irish National Liberation Army (INLA) “was not capable of undertaking a sustained campaign [against the British State], nor does it aspire to” according to the report.

It is also noted the creation of two new organizations, Oglaigh na hEireann (Irish Gaelic for “Volunteers of Ireland” and is used by the Irish Defence Forces and the various IRAs.) and the Republican Defence Army. However, the groups are small dissident factions according to the report.

The report also added that the two loyalist paramilitaries, the Ulster Defence Association (UDA) and the Ulster Volunteer Force (UVF) are also beginning to move from violence but at slower pace and not at a grassroots level like the IRA. Another loyalist paramilitary, the Loyalist Volunteer Force

The report was received warmly by Irish Toaiseach Bertie Ahern and British Prime Minister Tony Blair. Ahern, said “These positive and clear-cut findings are of the utmost importance and significance. It is time to make decisions and for Northern Ireland to look to the future.”

“The IRA has done what we asked it to do, and while issues like policing remain to be solved, the door is now open to a final settlement, which is why the talks next week in Scotland are going to be so important.” said Tony Blair in a live statement.

In a surprising reaction, the notoriously hardline leader of the Democratic Unionist Party, Ian Paisley, also welcomed the report. He believes that his party’s pressure is working and if Sinn Fein signs up to policing there could be a deal. Paisley said, “If the police question is settled absolutely on a democratic basis and principle we would have come a long way along the road.”

Sinn Fein leader Gerry Adams said “The DUP don’t have anything other than very limited options. They will or will not participate in power-sharing arrangements. If they don’t participate they are condemning people here, but particularly their own constituents, to second class public services, run by second class fly-in, fly-out British ministers. All the DUP can do is to delay, is to attempt to slow down, but they can’t stop the process of changing.”

Australian researchers say they have scientifically proven that stress causes sickness. The Garvan Institute in Sydney has discovered that a hormone, known as neuropeptide Y (NPY) is released into the body during times of stress. Their findings show the hormone can stop the immune system from functioning properly.

“Neuropeptide Y is one of those hormones that gets unregulated or released from neurones when stressful situations occur…it’s known for example that it regulates blood pressure and heart rates so your heart rate goes up but it hasn’t been known that it actually can affect immune cells as well,” said Professor Herbert Herzog, one of the researchers.

Herzog feels it is good to finally have proof of something people have suspected for so long.

“Now we have proven without doubt that there is a direct link and that stress can weaken the immune system and that makes you more vulnerable when you for example have a cold or flu and even in the more serious situations such as cancer can be enhanced in these situations,” said Herzog.

The Garvan Institute study centres on two key events that enable the human body to recognise foreign substances and control invaders. When our body encounters a pathogen (bacteria and viruses), the immune cells retain and interrogate suspects. Their activation is made possible by NPY. These cells then return to the lymph nodes, which are found all over the body, with information about the foreign invaders. The lymph nodes are where decisions about defence are made.

“Most of us expect to come down with a cold or other illness when we are under pressure, but until now we have mostly had circumstantial evidence for a link between the brain and the immune system,” said lead Garvan researcher, associate Professor Fabienne Mackay. “During periods of stress, nerves release a lot of NPY and it gets into the bloodstream, where it directly impacts on the cells in the immune system that look out for and destroy pathogens (bacteria and viruses) in the body.”

In the case of bacteria and viruses, TH1 cells are part of the attack team that is sent out on the ‘search and destroy’ mission. But when their job is done they need to be turned ‘off’ and the immune system reset. The same hormone, NPY, that activates the sentry cells now prompts the TH1 cells to slow down and die.

“Under normal conditions, circulating immune cells produce small amounts of NPY, which enables the immune cells on sentry duty and the TH1 immune cells to operate – it’s a yin and yang kind of situation. But too much NPY means that the TH1 attack is prevented despite the foreign invaders being identified – and this is what happens during stress,” added McKay.

The impact of stress on the body has been observed in athletes. Ph. D researcher at the University of Queensland, Luke Spence, together with the Australian Institute of Sport, studied elite and recreational athletes over five months.

They found elite athletes were more susceptible to respiratory diseases under stress.

“A lot of elite athletes put themselves through vast amounts of physical stress in their training, but also their emotional, psychological stress of feeling the pressure of Australia on their shoulders, wanting to compete and wanting to do their best,” said Spence.

It’s not just athletes who are prone to stress. Pressures at work and at home may cause emotional and mental stress that can be equally damaging. Almost a third of all work absenteeism in Australia is due to illness, costing employers over $10 billion a year.

“I think it has a huge impact for the work force and also for employers – if their employees are constantly stressed, constantly under pressure, they are more likely to get sick,” Spence said.

Further research could lead to the development of new drugs which may inhibit the action of the neuropeptide Y hormone.

Herzog warns people to minimise stress before it becomes a problem.

“Relaxation methods like yoga will help you to prevent that but there will still be people out there that are not responding to that and treatment by interfering with the system will be important,” he said. “There’s obviously some time until such a treatment will be available but this is something we will definitely work towards.”

The Garvan research will be published in the Journal of Experimental Medicine, Volume 202, No. 11.

In Seattle, on Sunday, Seattle Sounders FC beat the Portland Timbers 1–0 in the Cascadia Cup battle. Stefan Frei notched his fourth shutout this season while Clint Dempsey scored the winning goal in the 77th minute with an assist from Andy Rose. Seattle is now 1–0 in the cup while Portland falls to 0–2.

Portland almost scored minutes later when sub Fanendo Adi rattled the crossbar in the 81st minute. The Timbers also led the Sounders in shots with 11–10. Seattle was glad to have points before hitting the road. Head Coach Sigi Schmid added “We’ve got 13 points now in seven games, so we’re happy with that and we want to come back from these three road games with as many as possible.”

The total crowd on Sunday was tallied at 41,451. Seattle now stands at 4-2-1 with Portland struggling at 2-3-3. Portland hosts the Vancouver Whitecaps next weekend and Seattle travels to face New York City FC.

London, UK — The Vodafone GPRS (General Packet Radio Service) Mobile Data Network within the UK was off the air for several hours, but Vodafone staff were unable to supply any details as to how or why this had happened. The incident seems to have originated within Southern England, but spread “nationwide” within a short period.

Customers were therefore unable to access data services for a protracted period, including WAP browsing from mobile phones, email from personal devices like Blackberries and Windows Mobile Messengers, and full access over data cards from laptops.

Some criticism has been levelled at the company for failing to provide an easy source of information on the problem, with the only realistic option being to queue for a response from a call centre, as no information could be found on their public-facing website. This practice, whilst far from unique to Vodafone within the telecommunications industry, contrasts poorly with the common practice for most ISPs (Internet Service Providers), who conventionally provide a “system status” page on their website.

A diverse group of approximately 25 people gathered at the Johnson County Library on Monday to participate in reference librarian Scott Vieira’s class, Wikiwhatia? Wikipedia.

Scott opened the session by sharing a disparaging quote from Robert McHenry (former editor-in-chief of Encyclopedia Britannica) comparing Wikipedia to a public restroom. He then shared a quote from Andrew Keen, author of The Cult of the Amateur, in which he stated Wikipedia is the blind leading the blind. Scott shared Wikipedia usage data from a 2007 Pew Internet study showing 36% of adults have consulted Wikipedia and that that Wikipedia receives 10,000-30,000 searches per second. Scott also pointed out that Wikipedia now has over two million articles in English alone (over nine million articles in 250 languages). So there is a discrepancy here, lots of critics and lots of use.

Scott then shared some historical information in order to provide a context for understanding Wikipedia. This included some important names and dates in the history of encyclopedias… including Pliny the Elder (23-79 C.E.) who published 37 Volumes of Natural History, and Joachim Sterck van Ringelbergh (c. 1499-1556) who first used the term encyclopedia, and then d’Alembert and Diderot who published 17 volumes of their French Encyclopedia from 1751-1765. Encyclopedia Britannica was first published in Scotland in serial format 1768-1771.

Scott also discussed more recent history, sharing a photo of Ward Cunningham –who is credited with being the inventor of wiki software. Wikipedia was founded on Jan 15, 2001 by Larry Sanger and Jimmy Wales. Sanger left Wikipedia in 2002 and founded Citizendium in 2007 a complementary project which now has 4500 articles.

After the historical perspective, the class moved into using Wikipedia. Everyone in the audience had used Wikipedia. The class explored the content of Wikipedia, realising there is a whole lot going on. Scott demonstrated that the article about “frogs” for example, is semi-protected. The “history of science” article was examined, including the history of changes. Discussion covered how people contribute, who contributes and edits. The group also talked about Wikipedia bots, which aid in routine tasks in a semi-automated or automated fashion.

A discussion about teachers, school media specialists and students regarding their use of Wikipedia ensued. Some teachers and school media specialists are negative about Wikipedia, but Scott’s hope is that they will use it to start a discussion about the need to evaluate and critically think about information (even when it’s from more traditionally reviewed and edited sources).

An unanswered question from an audience member was, “What was the first Wikipedia article?”

Discussion topics from Scott to audience were as follows:

• Do you think Wikipedia is less accurate than published resources and how important is that accuracy to you?
• How do we determine authority on a subject? How important is it that an article be written by an expert? How is Wikipedia changing our idea of what an authority is?
• Currency – the ability to publish immediately – what are the advantages and what are the disadvantages?
• What do we think about the content selection in Wikipedia?
• Should Wikipedia be used by librarians?
• What do you think about the future of Wikipedia?
