US scientists have recreated the flu virus from the 1918 flu (aka ‘Spanish Flu’) via reverse genetics from lung tissue samples of persons who died from the pandemic. The flu was resurrected and injected into mice, according to Terrence Tumpey of the US Centers for Disease Control and Prevention, “to understand the biological properties that made the 1918 virus so exceptionally deadly.”

Disturbingly, the scientists have found genetic mutations and markers that are similar to those in flu viruses found in birds. This has raised concerns that the so-called “Asian bird flu” could spread to humans, becoming the next global flu pandemic.

200,000 litres of oil leaked into waters off the coast of Brisbane from the Pacific Adventurer when their fuel tanks were damaged in rough seas on Wednesday. The figure is about ten times higher than the original estimate of twenty thousand litres of oil. The devastating diesel oil spill has spread along 60 kilometres (37 miles) of the Queensland coast. In addition, 31 containers with 620 tonnes of ammonium nitrate fertiliser flew overboard during the violent storm.

Questions are being asked why the Hong Kong cargo ship was out in seas with nine meter waves caused by Cyclone Hamish, a Category 5 tropical cyclone, as well as why the fertiliser containers were not properly secured. One of the overboard containers ruptured the hull of the Pacific Adventurer, causing between 30 to 100 tonnes of oil to spew from the severely damaged ship.

If the ammonium nitrate mixes with the heavy oil, an explosion could occur. None of the containers have been recovered. Some of these may float, but it is believed that they may have sunk which then may cause algal blooms.

Disaster zones have been declared at Bribie and Moreton Islands, and along the Sunshine coast.

The vessel’s owner, Swire Shipping, reported that a second leak began on Friday, when the ship began listing after docking at Hamilton for repairs. “As full soundings of the vessel’s tanks were being taken at the port to determine how much oil had leaked from the vessel, a small quantity of fuel oil escaped from the Pacific Adventurer,” it stated. The ship was brought upright, and a recovery vessel was used to suck up the oil from the water. The leak produced a 500m-long oil slick down the Brisbane River. Booms were placed around this oil spill so that a skimmer could clean up the second spill.

Swire Shipping could face clean up costs of AU$100,000 a day as well as fines up to AU$1.5million (US$977,000; £703,000) if found guilty of environmental breaches or negligence.

Sunshine Coast beaches are slowly starting to be reopened. The beach of Mooloolaba was still closed following reports of burning sensations from swimmers. 12 beaches remain closed; however, 13 have been reopened.

Over 300 state government and council workers are using buckets, rakes and spades in the clean up effort. Sunshine Coast Mayor Bob Abbott says the majority will be gone by Sunday afternoon. The full environmental impact on wildlife is not yet known. One turtle and seven pelicans have been found covered in oil.

There are concerns that the drinking water of Moreton Island is at risk, as the island uses water from the underground water table near the oil spill site.

“Every bucketload of contaminated sand has to be removed from the island by barge, and each bucketload from a front-end loader weighs about one tonne. It’s just an impossible task,” said Mr Trevor Hassard of the Tangalooma Dolphin Education Centre.

The commercial fishing industry has suffered from the incident. Trawlers won’t resume operations until Sunday evening, and any catches will be tested for human consumption.

Bovine spongiform encephalopathy, better known as BSE or “mad cow” disease, may have been caused by human remains ingested by British cattle, two scientists said today.

Alan Colchester and his daughter Nancy Colchester, from the University of Kent and University of Edinburgh, respectively, suggested that the remains of humans cast into the Ganges in an Indian funeral rite contaminated Indian animal feed that was imported to the U.K. If some of the humans died of Creutzfeldt-Jakob disease, bone meal infected with CJD would have entered the British food chain, causing the similar BSE in cattle.

Admitting the evidence was not solid, the two scientists still argued that this new theory merited further review. The current theory of the origin of BSE involves the transmission of scrapie, a similar disease that affects sheep, to cattle. Prions, infectious proteins that would be the only disease-causing agents without nucleic acid, are thought to be the cause of all of these diseases.

A wet late Spring season’s increase in rainfall helped duck populations rebound in the northern Great Plains near the U.S.-Canadian border. A dry Winter and resulting low ground water levels threatened duck nesting grounds in the area.

Much to the relief of duck hunters, who feared a possible 2005 ban on duck hunting, the most-recent waterfowl survey released this week by the U.S. Fish and Wildlife Service showed duck populations in South Dakota on the rebound.

This contrasted to a May survey that showed fewer ducks and waterfowl nesting areas in the state with the population of breeding ducks numbering 1.6 million, down from 1.7 million in 2004. The same May survey indicated that duck habitats, specifically ponds, had declined more than 35 percent from the historical average.

However, late Spring rains reportedly improved wetland conditions and irrigated grasslands for grazing duck broods and re-nesting hens. The figures are used to set duck-hunting limits for the fall season, which begins in August.

“I have observed many duck broods across eastern South Dakota in July, and grassland cover looks great statewide,” Spencer Vaa, a waterfowl biologist with the South Dakota Department of Game, Fish and Parks said in an Associated Press report.

Anyone planning on attending the 2008 Summer Olympic Games in Beijing, China can forget about renting a car when they get there.

Newspapers reported on September 18 that no private cars would be allowed near any of the venues in the host city, in an attempt to combat the gridlock that has plagued the city.

Known for its stand-still traffic, Beijing’s transport authority believes it needs to curb at least 20% of traffic flow to ensure the Games run smoothly. The number of cars in the city is set to increase from 2.7 million to 3 million by the time of the Olympics. Country-wide, annual car sales are expected to reach 10 million annually by 2010.

A good infrastructure is one of the International Olympic Committee’s top priorities when searching for bid cities. The IOC requires that athletes, support staff such as coaches, venue volunteers, spectators, and the press all should be able to get from venue to venue without hassle.

Existing plans in Beijing say that private cars may only drive in the city on alternate days. Plates with odd numbers would drive one day, while even numbered licenses would drive the next day.

Wired magazine has suggested fuel-cell vehicles may be China’s next cultural revolution. Vancouver-based venture capitalist Mike Brown told the National Post: “If they get aggressive about this, and they decided to build up a fuel cell manufacturing capability to sell half a million of these things, they’ll get the costs down faster than anybody else.”

Financial analysts say Google is planning an e-wallet service that could eventually compete with eBay’s payment service PayPal. Google has not confirmed the development.

The rumor is a first sign of Google’s expected expansion of revenue sources to capitalize on its advertising customer base and search-engine traffic. What form that expansion will take has been a hotly debated subject for the company whose stock valuation momentarily made it the world’s biggest media company on June 7, 2005. Even Microsoft has been mentioned as a possible future competitor.

Ebay’s stock valuation dipped more than 2% on the news. Paypal currently accounts for one-fifth of the company’s revenues. But one business analyst saw potential benefit for Paypal[1], depending on exactly how the “Google Wallet” takes shape. The uncertainty underlined the lack of substantive information behind the rumor.

According to the New York Times, the CEO of a major online merchant, who spoke on the condition of anonymity, was approached by Google to take part in this service. Steve Langdon, a Google spokesperson, declined to comment.
