While nearly all coverage of the 2008 United States Presidential election has focused on the Democratic and Republican candidates, the race for the White House also includes independents and third party candidates. These parties represent a variety of views that may not be acknowledged by the major party platforms.

Wikinews has impartially reached out to these candidates, throughout the campaign. We now interview independent Presidential candidate Jon Greenspon, a veteran and small business executive.

A University of Tokyo group of researchers, led by bioengineer Shoji Takeuchi, has made an electronic sensor capable of smelling gases. The sensor uses genetically engineered frog cells. Since previous sensors were not very accurate, the scientist decided to try a biological approach. The invention was revealed in a US scientific journal yesterday, and is supposed to be used to design better machines to detect polluting gases in the atmosphere.

Previous smell sensors were based on quartz rods, which vibrate when a substance binds to them. The gases are distinguished by their molar masses, which can be similar for molecules with different structure, thus relatively often triggering a false positive. Trying to find a more accurate solution, Takeuchi decided to follow an example from insect world. As he explained, “when you think about the mosquito, it is able to find people because of carbon dioxide from the human. So the mosquito has CO2 receptors. When we can (extract) DNA (from the mosquito) we can put this DNA into the frog eggs to detect CO2.”

Genes of several insects (the silk moth, diamondback moth and fruit fly), injected into African clawed frog Xenopus laevis eggs, allowed them to produce relatively inexpensive and useful sensors. The choice of the species was caused by their widely studied and well-understood protein expression mechanism.

The modified cells responded to three kinds of pheromones and one odourant, which have similar chemical properties. When a molecule of an odorous substance adhered to the receptor on the membrane protein, ion channels opened for a certain period of time, and a current was generated. Its magnitude was clearly different for all four tested substances, allowing to distinguish between them accurately.

The colleagues embedded the sensor into a mannequin, so that it could shake its head when a gas was detected. It was easier to observe. Pheromones and molecules with quite similar molecule structure produced clearly distinguishable reaction, with higher accuracy than other biological or human-made sensors. As the research group said, the detection sensitivity of the odor sensor is several tens of parts per billion (ppb), and it is as high as the sensitivity of an existing odor sensor that uses an oxide semiconductor. The distinctive feature of the new sensor is its capability to selectively detect some odorous substances, rather than its sensitivity. Very few false positives were possible due to the biological mechanism involved.

At normal temperature, the sensor lifetime is about 12 hours, which can be extended by putting it into a refrigerator before first use.

Shoji Takeuchi says has a great hope for research use in future, since the frog eggs are very practical for genetic engineering, and can be conveniently used to develop smell sensors for a wide range of gases. He said, “The X. laevis oocyte has high versatility for the development of chemical sensors for various odorants. We believe that a shared ability to smell might open a new relationship between man and robot. .. The research will have wide implications… If the sensor is embedded in a nursing robot, it will be able to identify certain mouth odors or body odors. Also, it can be used for detecting CO2, air pollution, water pollution and food. It’s very important for the environment.”

Buffalo, New York —A massive warehouse complex of at least 5 buildings caught on fire in Buffalo, New York on 111 Tonawanda Street, sending a plume of thick, jet black colored smoke into the air that could be seen as far away as 40 miles.

As of 6:40 a.m., the fire was under control, and firefighters were attempting to stop it from spreading, but could not get to the center of the fire because of severe amounts of debris. Later in the morning, the fire was extinguished.

“The fire is mostly under debris at this point. It’s under control, but it’s under some debris. We really can’t get to it. We’re just going to have to keep on pouring water on it so it doesn’t spread,” said Thomas Ashe, the fire chief for the North Buffalo based fire division who also added that at one point, at least 125 firefighters were on the scene battling the blaze. One suffered minor injures and was able to take himself to the hospital to seek medical attention.

Shortly after 8:00 p.m. as many as 3 explosions rocked the warehouse sending large mushroom clouds of thick black smoke into the air. After the third explosion, heat could be felt more than 100 feet away. The fire started in the front, one story building then quickly spread to three others, but fire fighters managed to stop the flames from spreading onto the 3 story building all the way at the back.

According to a Buffalo Police officer, who wished not to be named, the fire began at about 7:00 p.m. [Eastern time], starting as a one alarm fire. By 8:00 p.m., three fire companies were on the scene battling the blaze. Police also say that a smaller fire was reported in the same building on Saturday night, which caused little damage.

At the start of the fire, traffic was backed up nearly 4 miles on the 198 expressway going west toward the 190 Interstate and police had to shut down the Tonawanda street exit because the road is too close to the fire.

At one point, traffic on the 198 was moving so slow, at least a dozen people were seen getting out of their cars and walking down the expressway to watch the fire. That prompted as many as 10 police cars to be dispatched to the scene to force individuals back into their cars and close off one of the 2 lanes on the westbound side.

One woman, who wished not to be named as she is close to the owner of the warehouse, said the building is filled with “classic cars, forklifts, and money” and that owner “does not have insurance” coverage on the property. The building is not considered abandoned, but firefighters said that it is vacant.

Officials in Fort Erie, Ontario were also swamped with calls to fire departments when the wind blew the smoke over the Niagra River and into Canada.

It is not known what caused the fire, but a car is suspected to have caught on fire and there are reports from police and hazmat crews, that there were also large barrels of diesel fuel being stored in one building. Firefighters say the cause of the blaze is being treated as “suspicious.” The ATF is investigating the fire and will bring dogs in to search the debris.

Chinese authorities say they are preparing to launch a crackdown on melamine-laced milk after the scandal over tainted products, which made hundreds of thousands of children ill two years ago and damaged China’s brand reputation overseas, resurfaced.

China has dispatched inspectors to sixteen provinces to urge local governments to thoroughly investigate cases concerning food safety.

The decision comes after milk products tainted with the industrial chemical melamine were removed from sale in Shanghai and the provinces of Shaanxi, Shandong, Liaoning and Hebei, the state-run Xinhua News Agency said.

At least twenty-six people have been killed in Karachi, Pakistan after four days of ethnic killings, according to police officials. The officials said that nine people were killed on Monday in the city’s Orangi western neighbourhood, which has a majority ethnic Pashtun community.

The Sindh government has awarded special powers to the Pakistan Rangers under Section 5 of the Anti-Terrorism Act 1997 and imposed Section 144 in the limits of 26 police stations for a month.

At least forty people were killed as ethnic clashes erupted across the city in early January.Home minister of Sindh province, Dr Zulfiqar Mirza has called upon the Army to restore peace and order.

Western Australian Master Builders Association (MBA) yesterday demanded the Carpenter Government call an emergency cabinet meeting to avoid a “state of emergency” over the energy crisis gripping WA. A MBA spokesperson said that hundreds of workers have already been stood down, many without pay, and that the cost of building material is soaring.

The Minister for Energy, Fran Logan has admitted that the gas shortage caused by Tuesday’s fire is damaging the economy as mining, manufacturing and construction industries wind back operations. Western Australia’s two major brick producing companies have shut operations and Wesbeam’s $A100 million Neerabup pine production facility has been closed, their 130 employees have been stood down.

Wesbeam chief executive James Malone said, “It’s an industrial tsunami in my view. It’s a little ripple that has very quickly had a huge multiplying effect on the whole community”.

Michael McLean, Master Building Association director said “It’s a worst-nightmare scenario, and not one we could have imagined in our wildest dreams,” building supplies are expected to start running out by the middle of next week.

Premier Carpenter has announced a meeting of ministers and industry representatives to take place on Sunday to discuss solutions to the growing crisis. Tim Wall, managing director of Apache Corporation has said Apache is conducting a worldwide search for the parts need to repair the pipeline.

Major mining companies and Apache partners BHP Billiton and Rio Tinto have already reported they are suffering with the loss of gas supply; the Chamber of Minerals and Energy has talked down the effect saying that they don’t expect the crisis to take the heat off the booming mining industry.

Opposition leader Troy Buswell has describe the performance of Fran Logan as “absolutely dismal” noting that Mr Logan had experienced a similar incident in January this year, when a fire at Woodsides Karratha operations had a similar effect.

Scientists have uncovered the largest Neolithic settlement in the United Kingdom at the Durrington Walls and believe that the village was inhabited by the people who built the Stonehenge monument.

Scientists say that the village was built around 2,600 B.C., roughly when Stonehenge was believed to have been constructed, and housed over 100 people.

Inside the areas which would have been the interior of houses at the time, scientists also found outlines of what they think were beds and cupboards or dressers. Pieces of pottery and “filthy” rubbish around the site. Animal bones, arrowheads, stone tools and other relics were also discovered.

“We’ve never seen such quantities of pottery and animal bone and flint. In what were houses, we have excavated the outlines on the floors of box beds and wooden dressers or cupboards,” said Sheffield University archaeologist Mike Parker Pearson.

So far, the dig has revealed at least 8 houses roughly 14-16 feet square, but scientists say that they think there may have been at least 25 altogether.

The site was likely to have been occupied only seasonally rather than year-round and evidence suggests that a lot of “partying” went on at the location.

“The animal bones are being thrown away half-eaten. It’s what we call a feasting assemblage. This is where they went to party – you could say it was the first free festival. The rubbish isn’t your average domestic debris. There’s a lack of craft-working equipment for cleaning animal hides and no evidence for crop-processing,” added Pearson.

The Durrington Walls are approximately 2 miles from the Stonehenge site.

Scientists have announced that the largest radio telescope array in the world, the Square Kilometer Array (SKA) is to be built in either Africa or Australia and will be composed of thousands of antenna arrays that will be capable of detecting the first galaxies and stars formed in our universe. The control center for the array is announced to be located in the United Kingdom in Manchester, England at the Jodrell Bank Centre for Astrophysics.

“The next generation radio telescope – the Square Kilometer Array – will carry on this tradition of innovation. The goal is to construct a network of antennas working at centimeter to meter wavelengths with 100 times the sensitivity of the largest existing arrays. This telescope will play a major role in the following decades, alongside other next generation facilities in the millimeter, optical/IR, X-ray and so on, in further exploring the content and evolution of the universe,” said a press released on SKA’s website.

Construction will begin in 2012 and cost over US$2 billion (£1 billion, €1.4 billion) to build. The array will reportedly begin operation by the year 2020. SKA decided to release the details of the array plans on the 50th anniversary of the launch of Sputnik. At least 17 different countries and 55 schools, universities, engineers and astronomers are expected to take involvement in the project.

The array will be built in one of two locations. The first option is in Mileura, Australia. According to SKA’s website, the location is ideal because “only 100,000 people inhabit the five million square kilometers of the interior” area of western Australia, making it one of “the most radio-quiet locations on Earth.”

The second option is in South Africa in Northern Cape Province because of the “dry climate, a good existing infrastructure of roads and power reticulation, a low Radio Frequency Interferences (RFI), low land prices and low operating costs” and “has a appropriately skilled workforce and a well-established telecommunications infrastructure,” says SKA’s website.

The array is going to be more than 50 times as powerful as the Arecibo Observatory in Puerto Rico, which is currently the largest radio telescope on the planet.



Monday, January 2, 2006Firefighters in the Australian state of New South Wales continue to battle bushfires across the state.

Rural Fire Service Commissioner Phill Koperberg said that there are still three fires on the Central Coast, while another fire in Junee is moving north and is now spread over 35,000 hectares.

He added that it could take up to four days to contain the fires due to rain and strong winds. A southerly change blew through the state last night, easing temperatures and reducing the fire threat. No homes are believed to be under direct threat at this time.

It is feared that the weather which helped the fires take hold may return on the weekend.

Fires on the Central Coast fires continue to affect road and rail transport between Sydney and Newcastle.

The Sydney-Newcastle Freeway and the Pacific Highway have been reopened, although there is heavy traffic on the freeway at Brooklyn and Cowan. Drivers have been advised to exercise caution due to thick smoke. Trains travelling between the Central Coast and Newcastle to Sydney are heavily delayed.

Only one person has been killed by the fires, a 65 year old man who suffered a heart attack while helping residents evacuate on the Central Coast.

27 fires are reported to be burning across New South Wales.

General Motors Corporation (GM), an American automaker which has filed for bankruptcy protection, announced on Friday that the Penske Automotive Group (PAG) was selected to purchase Saturn Corporation. The transaction should be completed in October.

The purchase includes rights to the Saturn brand, its five current models and its dealership network. Two models would be discontinued, the Sky and Astra. GM would continue building the Aura sedan, the SUV’s, Vue and Outlook for at least two more years.

Saturn has 350 dealers across the United States. The dealers employ more than 13,000 jobs and sell only the Saturn autos. Canadian Saturn dealers are not included in the deal.

According to Penske future Saturn vehicles will be fuel economy focused. An expert indicated that this would move Saturn back to its roots of a entry level car company. PAG is in talks with several international automakers to replace GM after 2011. Automotive News reports that Renault Samsung Motors of Korea is the most likely candidate.

Penske wants Jill Lajdziak, Saturn’s general manager, and Tom LaSorda, former Chrysler President to head up the company when it is independent of GM.

Serra Automotive in Grand Blanc Township, Genesee County, Michigan, is in talks to take a partial ownership in a new Saturn lead by Penske.
