The Svalbard Global Seed Vault, a vault containing millions of seeds from all over the world, saw its first deposits on Tuesday. Located 800 kilometers from the North Pole on the Norwegian island of Spitsbergen, the vault has been referred to by European Commission president José Manuel Barroso as a “frozen Garden of Eden“. It is intended to preserve crop supplies and secure biological diversity in the event of a worldwide disaster.

“The opening of the seed vault marks a historic turning point in safeguarding the world’s crop diversity,” said Cary Fowler, executive director of the Global Crop Diversity Trust which is in charge of collecting the seed samples. The Norwegian government, who owns the bank, built it at a cost of $9.1 million.

At the opening ceremony, 100 million seeds from 268,000 samples were placed inside the vault, where there is room for over 2 billion seeds. Each of the samples originated from a different farm or field, in order to best ensure biological diversity. These crop seeds included such staples as rice, potatoes, barley, lettuce, maize, sorghum, and wheat. No genetically modified crops were included. (Beyond politics they are generally sterile so of no use.)

Constructed deep inside a mountain and protected by concrete walls, the “doomsday vault” is designed to withstand earthquakes, nuclear warfare, and floods resulting from global warming. Norwegian Prime Minister Jens Stoltenberg called it an “insurance policy” against such threats.

With air-conditioned temperatures of -18 degrees Celsius, experts say the seeds could last for an entire millennium. Some crops will be able to last longer, like sorghum, which the Global Crop Diversity Trust says can last almost 20 millenniums. Even if the refrigeration system fails, the vaults are expected to stay frozen for 200 years.

The Prime Minister said, “With climate change and other forces threatening the diversity of life that sustains our planet, Norway is proud to be playing a central role in creating a facility capable of protecting what are not just seeds, but the fundamental building blocks of human civilization.” Stoltenberg, along with Kenyan Nobel Peace Prize laureate Wangari Maathai, made the first deposit of rice to the vault.

“It is very important for Africa to store seeds here because anything can happen to our national seed banks,” Maathai said. The vault will operate as a bank, allowing countries to use their deposited seeds free of charge. It will also serve as a backup to the thousands of other seed banks around the world.

“Crop diversity will soon prove to be our most potent and indispensable resource for addressing climate change, water and energy supply constraints and for meeting the food needs of a growing population,” Cary Fowler said.

A robotic system at Stanford Medical Center was used to perform a laparoscopic gastric bypass surgery successfully with a theoretically similar rate of complications to that seen in standard operations. However, as there were only 10 people in the experimental group (and another 10 in the control group), this is not a statistically significant sample.

If this surgical procedure is as successful in large-scale studies, it may lead the way for the use of robotic surgery in even more delicate procedures, such as heart surgery. Note that this is not a fully automated system, as a human doctor controls the operation via remote control. Laparoscopic gastric bypass surgery is a treatment for obesity.

There were concerns that doctors, in the future, might only be trained in the remote control procedure. Ronald G. Latimer, M.D., of Santa Barbara, CA, warned “The fact that surgeons may have to open the patient or might actually need to revert to standard laparoscopic techniques demands that this basic training be a requirement before a robot is purchased. Robots do malfunction, so a backup system is imperative. We should not be seduced to buy this instrument to train surgeons if they are not able to do the primary operations themselves.”

There are precedents for just such a problem occurring. A previous “new technology”, the electrocardiogram (ECG), has lead to a lack of basic education on the older technology, the stethoscope. As a result, many heart conditions now go undiagnosed, especially in children and others who rarely undergo an ECG procedure.

Queues have started to form today outside the London Apple store for the launch of the iPhone. The phone launches tomorrow at 6.02 p.m. UTC exclusively onto the O2 network amid controversy. The iPhone was launched five months ago in the United States and is set to launch in the United Kingdom and Germany tomorrow.

Many people have braved the poor weather and have set up camp in the street in a bid to be the first of many thousands to buy the product on the first day of it’s release in the UK. Apple have already sold 1.4 million of the units in the US, some of which have already been imported into the UK un-officially. The cost of the device is set as £269 on a minimum £35 per month contract and will be sold at The Carphone Warehouse, O2 and Apple Stores across the UK.

The iPhone has a touch screen display and can act as a phone, text device, web browser, music player and email client all in one. The launch of the product onto one phone network only has caused controversy internationally and has led to many people using free and paid methods of unlocking the phone to be able to use it on other networks even though it voids the warranty. Apple replied to this move by releasing software patches that, when installed, will prevent functionality of the phone.

In Vancouver, a 20-year urban success story may yet have a sad ending. The city’s downtown population has doubled to 80,000 in the last 20 years thanks to Vancouver’s “Living First” policy – a planning strategy that favors residential development over commercial. And planners are expecting the population to reach more than 120,000 by 2030. But while downtown booms with people, business is busting. The International Herald Tribune reports that the city’s recently-released jobs and land-use study is estimating that downtown Vancouver may run out of commercial and office space within 5 years.

The ‘Vancouver problem’ is one that many cities in the United States could only hope to have. On the contrary, much effort has been put into bringing residential life back into the city centres. In Los Angeles, San Diego, Miami, and Washington, D.C. there has been a condominium boom in recent years, but these cities are far from the situation Vancouver faces now.

To counter the trend in Vancouver, planners are proposing changes to the city’s zoning regulations, including the passage of more lenient building height restrictions. But because residential developments are so much more profitable than commercial and office space, some public officials are proposing offering better incentives to the developers willing to build commercial. Another option is to expand the moratorium that was placed on new housing development in the central business district two years ago.

Translink is currently involved in a major expansion of the 49.5 km (30.8 mi) Skytrain system centred on downtown Vancouver. Construction of the Canada and Evergreen lines is underway. The former will be complete in 2009, and the latter in 2011.

Israel has purchased two more Dolphin class submarines which have the capacity to carry nuclear warheads. Israel already has three older nuclear weapons-capable Dolphin submarines but the new Dolphins have propulsion systems that allow them to remain submerged for longer periods of time, according to the Jerusalem Post, making it harder for them to be tracked by satellite. Experts view the purchase as a clear signal to Iran that Israel can retaliate if subjected to a nuclear attack.

“The Iranians would be very foolish if they attacked Israel,” said Paul Beaver, a British based defence analyst, speaking to the Washington Post. According to Beaver, the submarines would provide Israel with both first strike and second strike capability.

Israel already has land-based nuclear-capable ballistic missiles in the form of the Jericho I and II missiles.

German officials confirm that the contracts for the new submarines was signed July 6. The Jerusalem Post reports that they will be operational shortly.

Israel has never confirmed nor denied that it has nuclear weapons but is believed to have the world’s sixth largest stockpile of the devices, with most outside estimates putting their stockpile in the low hundreds. Israel’s possession of nuclear arms has often been a locus of bitter controversy in the Middle East, especially among countries who believe that the world community, and especially the United States, is hypocritical in its tolerance of Israeli nuclear arms while decrying the efforts of other Middle Eastern nations to develop their own nuclear capabilities.

Meanwhile, the Jerusalem Post reports there is a growing mood among Israel’s defence establishment that the country will have to act independently to stop Iran from obtaining nuclear weapons as the United States is unlikely to do so.

“America is stuck in Iraq and cannot go after Iran militarily right now,” according to an unnamed official quoted by the paper.

A report by the US House of Representatives’ Intelligence Committee released on Wednesday asserts that if Iran arms itself with nuclear weapons, Israel would be pressed to respond militarily. “A nuclear armed Iran would likely exacerbate regional tensions. Israel would find it hard to live with a nuclear armed Iran and could take military action against Iranian nuclear facilities,” the report states. Iran has continually maintained that it seeks only to develop nuclear technology for the production of electrical power, though this has been disputed by many nations.

New reports indicate that the proliferation of the Conficker computer worm (also known as Kido or Downadup) has nearly quadrupled in the last four days. The worm has gone from just over 2 million Microsoft Windows computers infected to 8.9 million, according to estimates by anti-virus company F-Secure. Though Microsoft issued a patch with a severity rating of “critical” in mid-October 2008, just days after Conficker was first discovered, many business computers still have not applied the patch.

Most to all of the infected computers are on corporate networks; Conficker cannot spread through the Internet or e-mails. Instead, when an infected laptop connects to a corporate network, the worm searches for vulnerable computers and attempts to guess its password. Conficker also infects any network shares the user may be connected to. The worm has a list of about one hundred common passwords, including “password” and “qwerty“. Conficker also infects USB sticks, which then infect any Microsoft Windows computer the stick is plugged in to.

After it gains access to the computer, Conficker adds itself to the Windows processes “services.exe”, “explorer.exe” and “svchost.exe”, then makes a copy of itself as a DLL file with a random five- to eight-character name. The worm also disables Windows services such as Windows Update and Windows Defender. Conficker also blocks access to most security-related sites, including Windows Update. The worm then checks several websites for the current date, then generates a domain name based on that date and downloads infected files from that domain. This domain is believed to be in Ukraine. Conficker makes itself very hard to remove by registering the downloaded files as kernel drivers and the DLL copy of itself of a service.

Microsoft has advised users to install the patch (security bulletin MS08-067), then run the latest edition of the Windows Malicious Software Removal Tool.

Peter Costello’s budget announcement has led to rejoicing for small businesses, but the lack of joy for those pushing for radical corporate taxation reform has led to many businesses asking “what about us?”

Personal taxation and small business have been the big winners after this year’s federal budget. Although dampened by the twin economic threats of rising interest rates and petrol prices, there should be a reasonable amount of real income savings for both low and high income earners, with those receiving Medicare, or a superannuation benefit, privy to an even lower level of taxation (0% for those on super benefits).

Small business also has benefited from the Howard government’s 11th annual budget, with them receiving a higher level of reducing depreciation, leading to a higher level of deductions in the years following the uptake of new technology or other capital. They are also privy to a AU$435 million dollar tax cut to compensate for their changing accounting requirements under the government’s new AIFRS reporting standards, as well as increasing the uptake of both the small business tax relief scheme and CGT (Capital Gains tax) Concessions.

The budget was not a complete loss for big business however, as superannuation laws have been tweaked to streamline contribution and payment rules previously impeding those with multitudes of staff.

But this is not enough, says Big 4 accounting firm Ernst & Young. In their newly published paper “Taxation of Investment in Australia: the need for ongoing reform”. In it they lead the charge for a greater streamlining and organization of the corporate tax system in Australia, submitting that it will lead to reductions in “disincentives to work save and invest in Australia [as well as improving] the international competitiveness of Australian businesses.” This follows from a recent report brought out by Mr. Costello himself about the need for tax reform in Australia.

A budget night Mr. Costello was notably coy about any future reform of corporate tax in Australia. He alluded to the report by his ministers but kept from outlining the government’s plan precisely.
