Glasgow International Airport in Renfrewshire, Scotland was evacuated after a green Jeep Cherokee struck the airport’s terminal building and burst into flames at 1511 BST.

An eyewitness told the BBC that “[A] man was on fire.” All flights are grounded, and two men have been arrested and the United Kingdom has raised the national threat level to “critical” which means another terror attack is imminent.

Eyewitnesses described a Jeep speeding toward the building with flames coming out from underneath. They also reported seeing two Asian men in the car, one of whom was on fire.

The BBC quoted an eyewitness as saying that two attempts were made to ram the Jeep through the wall, and that the passenger was holding a lit Molotov Cocktail and made several attempts to throw the bottle.

The Strathclyde Police Chief announced that the event is being linked to the earlier attempted car bombings in London, and as such is being treated as a terrorist investigation.

Eyewitnesses are now saying that one of the two men was pouring bottles of petrol into the car’s interior and onto himself, before running from the car, on fire, into the main terminal building. Witnesses have also reported that gas cylinders were removed by bystanders from the burning vehicle.

According to the BBC, the driver of the vehicle put up a violent struggle before being overpowered by the police and public. One person who tackled him was Stephen Clarkson, a member of the public.

Richard Gray, an eyewitness to the event, stated “There was an Asian guy who was pulled out of the car by two police officers.”

Seven people have been taken to local hospitals with injuries.

Police said that this incident was a deliberate attempt and not a road accident. Officials have also said that the incident is connected to earlier attempted car bombings in London the day before.

Two people have been arrested, one of whom was badly burned. Seven known casualties, including the Asian male have been taken to the Royal Alexandra Hospital, Paisley.

While the suspect was being treated in the hospital, a suspect device was discovered in the hospital, resulting in the partial evacuation of the building while the device was moved to a safe area. This object later turned out to be mundane, although initial reports believed it to be a suicide belt.

The BBC announced that the Prime Minister is being kept fully informed. He chaired a meeting of Civil Contingencies Committee (COBRA) at 1900 (BST), after which the Home Secretary, Jacqui Smith, announced that the national threat level been elevated from “Severe” to “Critical”, meaning another attack is expected “imminently.”

Officials at Edinburgh Airport have said that all cars are being turned away from the airport, and at Heathrow in London, passengers are being advised not to bring private cars near to the terminal buildings. Some passengers were kept waiting in planes while the area was secured.

The first bomber, who was taken to Govan high security prison, has now been interviewed, though no further statements from Strathclyde police have been forthcoming. The second bomber, who was taken to the Royal Alexandria hospital in Paisley, is listed in critical condition tonight, and is being kept under 24-hour guard.

2,300 passengers who were due to set off from Glasgow Airport today have been driven by coach to a conference centre, where a reception area has been set up for them.

Two people were arrested by The Metropolitan Police Anti-Terrorist Branch on the M6 motorway in Cheshire in connection with the Glasgow International Airport attack and attempted London car bombings.

The Prime Minister Gordon Brown is expected to hold another COBRA meeting with other members of the Cabinet today. This will be the fifth COBRA meeting in 48 hours.

American film director John Hughes, noted for such movies as Sixteen Candles, Pretty in Pink and The Breakfast Club, died Thursday due to a heart attack.

A statement, released by his representative, said that he experienced the heart attack while on a morning stroll in Manhattan, New York. Hughes was born on February 18, 1950 in Michigan. He started his career as an advertising copywriter in Chicago. By the end of the 1970s he was a frequent contributor to the National Lampoon magazine.

In the 1990s, he made the Home Alone series, which became a box office sensation and turned Macaulay Culkin into a star.

In recent years, Hughes stepped back from the movie industry to spend more time with his family. He is survived by his wife of 39 years, Nancy, two sons and four grandchildren.

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.

Thomas Charles Damron, aged 22, was charged in the death of 18 year old Kathryn Sutherland, killed Saturday afternoon in a four-car crash Saturday afternoon near Romeo, Michigan.

Damron, arraigned Monday afternoon, was charged with operating a vehicle with the presence of drugs causing death, possession of marijuana, and negligent homicide. Preliminary investigations indicate that Damron crashed into the rear of another vehicle starting a chain reaction that ultimately led to still another car crossing into the westbound lane where it struck the victim’s car.

Kathryn Sutherland died after she was airlifted to the University of Michigan Medical Center.

Electronic Gaming Monthly is now dead. EGM was one issue away from its 20th anniversary in February 2009. An internal email leaked to industry website Gamasutra on Tuesday revealed that EGM was to be closed following the acquisition of the online element of the 1UP network by competitor Hearst Corporation‘s UGO Entertainment and that the January 2009 issue (with Wolverine on the cover) would be the final printed issue of the iconic magazine. Ziff Davis‘s sale, brokered by GCA Savvian Advisors also includes Mycheats.com, Gametab.com, and GameVideos.com. Hearst Interactive is the owner and operator of UGO Entertainment.

According to CEO Jason Young, the court proceedings help Ziff Davis “pay down debt and shift our full focus to our core PCMag Digital Network Business.” Davis had been focusing on PCMag Digital Network. As a result, around 30 employees of Ziff Davis’ Game Group, including EGM Magazine’s staff, 1UP Network’s web staff, podcast and video producers lost their jobs. A UGO spokesman explained that “the reality is that UGO Entertainment is saving over 25 jobs, the company is retaining a core group of editorial all-star performers.” Ziff Davis Holdings Inc (ZFDH.PK), which publishes EGM and about 15 Web sites, obtained Manhattan, New York Court Judge Burton Lifland’s approval of a reorganization plan under Chapter 11, Title 11, United States Code. It was able, therefore, to emerge from its duly filed March bankruptcy protection petition.

UGO Entertainment CEO J Moses left a note on EGM’s gaming legacy, saying, “since we started UGO 11 years ago, we have served the gamer community and built a world-class online publishing platform.” Ziff Davis Media CEO Jason Young further noted: “We believe this is a smart transaction for Ziff Davis Media that places these market leading assets and teams in a great environment poised for further success. The transaction allows us to pay down debt and shift our full focus to our core PCMag Digital Network business. We thank our 1UP team members for their contributions and wish them the best of success into the future.” In July 2007, Hearst acquired the 11-year-old UGO Networks (Hearst Interactive) for an estimated price of $100 million. Established in 1998 by CEO J Moses, UGO is an online site targeting men aged 18 to 34.

J Moses stated categorically that his company just saved 1UP and UGO never tried to acquire EGM. “Closing EGM has absolutely nothing to do with UGO. We have just hired 24 people and have expanded UGO by 33 percent, because our business is robust and growing. We only wanted to buy 1UP and related sites. That was our interest as a dot-com company and that’s all we’ve ever been for 11 years.” Sam Kennedy, editorial director of 1UP, further explained that Ziff Davis was insolvent and 1UP was not financially healthy. “The reality of the market was that no company, including UGO, was willing to sustain 1UP as it was so the cuts were very painful but necessary to the survival of 1UP,” he added.

Electronic Gaming Monthly, which has been synonymous to video games for generations of gamers, was an American consumer video game magazine mainstay. It was published by Ziff Davis as part of the 1UP Network and released 12 issues a year (and an occasional extra “13th” issue for the Christmas season, also known as the “Smarch” issue, a reference to an episode of The Simpsons). As ZD’s sole print magazine, EGM, a stalwart of the videogame industry and dubbed the New York Times of games journalism, has been losing money. The 20-year-old publication had 236 issues total, since its debut in 1989.

In 2008, the company closed 27-year Games for Windows Magazine, or Computer Gaming World. In late 2006, Ziff-Davis also shuttered its Official U.S. PlayStation Magazine, while its Xbox-focused XBN and Electronics Boutique in-store mag GMR were terminated in 2004. EGM’s February issue, which is completed, will only be available digitally. Print publications have been suffering for years now, due to the global economic meltdown.

Wireless provider Sprint announced today, that they would be working with RealNetworks to launch a streaming music service, for Sprint wireless customers, called Rhapsody Radio.

The service will allow users to listen to podcasts and six streaming radio stations (rap, hip-hop hits, alternative, country, ’70s, and music news) from their mobile phone. Users will be able to listen to live broadcasts of those stations over their cellular connection. For a monthly subscription fee of $6.95, users will also have unlimited access to commercial-free radio broadcasts. Selected streaming podcasts from KCRW, Santa Monica 89.9 FM, and National Public Radio’s Southern California station will also be available. A special Beats N Breaks stream is also available. Beats N Breaks provides background music from hip-hop songs for users to rap with.

Rhapsody Radio service requires a Sanyo MM-7400, Sanyo MM-5600, Sanyo MM-8300, Samsung IP-A790, Samsung MM-A800, Samsung MM-A880 or an LG MM-535 mobile phone. Customers are able to order directly from their phones, with the charge appearing on their next bill.

Many analysts predicted the introduction of music services by other wireless providers after Apple recently introduced the Motorola ROKR. The Motorola ROKR comes with a version of the iTunes software which allows users to listen to up to 100 songs on their phone. Service for this phone in the USA is provided by Cingular Wireless.

Planetary scientist Vlada Stamenkovi? of the NASA Jet Propulsion Laboratory and colleagues have developed a new chemical model of how oxygen dissolves in Martian conditions, which raises the possibility of oxygen-rich brines; enough, the work suggests, to support simple animals such as sponges. The model was published in Nature on October 22. Wikinews caught up with him in an email interview to find out more about his team’s research and their plans for the future.

The atmosphere of Mars is far too thin for humans to breathe or for lungs like ours to extract any oxygen at all. It has on average only around 0.6% of the pressure of Earth’s atmosphere, and this is mainly carbon dioxide; only 0.145% of the thin Martian atmosphere is oxygen. The new model indicated these minute traces of oxygen should be able to enter salty seeps of water on or near the planet’s surface at levels high enough to support life forms comparable to Earth’s microbes, possibly even simple sponges. Some life forms can survive without oxygen, but oxygen permits more energy-intensive metabolism. Almost all complex multicellular life on Earth depends on oxygen.

“We were absolutely flabbergasted […] I went back to recalculate everything like five different times to make sure it’s a real thing,” Stamenkovi? told National Geographic.

“Our work is calling for a complete revision for how we think about the potential for life on Mars, and the work oxygen can do,” he told Scientific American, “implying that if life ever existed on Mars it might have been breathing oxygen”.

Stamenkovi? et al cite research from 2014 showing some simple sponges can survive with only 0.002 moles of oxygen per cubic meter (0.064 mg per liter). Some microbes that need oxygen can survive with as little as a millionth of a mole per cubic meter (0.000032 mg per liter). In their model, they found there can be enough oxygen for microbes throughout Mars, and enough for simple sponges in oases near the poles.

In 2014, also suggesting multicellular life could exist on Mars, de Vera et al, using the facilities at the German Aerospace Center (DLR), studied some lichens, including Pleopsidium chlorophanum, which can grow high up in Antarctic mountain ranges. They showed those lichens can also survive and even grow in Mars simulation chambers. The lichens can do this because their algal component is able to produce the oxygen needed by the fungal component. Stamenkovi? et al’s research provides a way for oxygen to get into the Martian brines without algae or photosynthesis.

Stamenkovi? et al found oxygen levels throughout Mars would be high enough for the least demanding aerobic (oxygen-using) microbes, for all the brines they considered, and all the methods of calculation. They published a detailed map^[3] of the distributions of solubility for calcium perchlorates for their more optimistic calculations, which they reckoned were closer to the true case, with and without supercooling. The lowest concentrations were shown in the tropical southern uplands. Brine in regions poleward of about 67.5° to the north and about 72.5° to the south could have oxygen concentrations high enough for simple sponges. Closer to the poles, concentrations could go higher, approaching levels typical of sea water on Earth, 0.2 moles per cubic meter (6.4 mg per liter), for calcium perchlorates. On Earth, worms and clams that live in the muddy sea beds require 1 mg per liter, bottom feeders such as crabs and oysters 3 mg per liter, and spawning migratory fish 6 mg per liter, all within 0.2 moles per cubic meter, 6.4 mg per liter.

((Wikinews)) Does your paper’s value of up to 0.2 moles of oxygen per cubic meter, the same as Earth’s sea water, mean that there could potentially be life on Mars as active as our sea worms or even fish?

Stamenkovi?: Mars is such a different place than the Earth and we still need to do so much more work before we can even start to speculate.

Stamenkovi? et al studied magnesium and calcium perchlorates, common on Mars. They found the highest oxygen concentrations occur when the water is colder, which happens most in polar regions.

((WN)) The temperatures for the highest levels of oxygen are really low, -133 °C, so, is the idea that this oxygen would be retained when the brines warm up to more habitable temperatures during the day or seasonally? Or would the oxygen be lost as it warms up? Or — is the idea that it has to be some exotic biochemistry that works only at ultra low temperatures like Dirk Schulze-Makuch’s life based on hydrogen peroxide and perchlorates internal to the cells as antifreeze?

Stamenkovi?: The options are both: first, cool oxygen-rich environments do not need to be habitats. They could be reservoirs packed with a necessary nutrient that can be accessed from a deeper and warmer region. Second, the major reason for limiting life at low temperature is ice nucleation, which would not occur in the type of brines that we study.

Stamenkovi? et al’s paper is theoretical and is based on a simplified general circulation model of the Mars atmosphere — it ignores distinctions of seasons and the day / night cycle. Stamenkovi?’s team combined it with a chemical model of how oxygen would dissolve in the brines and used this to predict oxygen levels in such brines at various locations on Mars.

When asked about plans for a future model that might include seasonal timescales, Stamenkovi? told Wikinews, “Yes, we are now exploring the kinetics part and want to see what happens on shorter timescales.”

Stamenkovi? et al’s model also takes account of the tilt of the Mars axis, which varies much more than Earth’s does.

Wikinews asked Stamenkovi? if he had any ideas about whether and how sponges could survive through times when the tilt was higher and less oxygen would be available:

((WN)) I notice from your figure^[4] that there is enough oxygen for sponges only at tilts of about 45 degrees or less. Do you have any thoughts about how sponges could survive periods of time in the distant past when the Mars axial tilt exceeds 45 degrees, for instance, might there be subsurface oxygen-rich oases in caves that recolonize the surface? Also what is the exact figure for the tilt at which oxygen levels sufficient for sponges become possible? (It looks like about 45 degrees from the figure but the paper doesn’t seem to give a figure for this.)

Stamenkovi?: 45 deg is approx. the correct degree. We were also tempted to speculate about this temporal driver but realized that we still know so little about the potential for life on Mars/principles of life that anything related to this question would be pure speculation, unfortunately.

((WN)) How quickly would the oxygen get into the brines — did you investigate the timescale?

Stamenkovi?: No, we did not yet study the dynamics. We first needed to show that the potential is there. We are now studying the timescales and processes.

((WN)) Could the brines that Nilton Renno and his teams simulated, forming on salt/ice interfaces within minutes in Mars simulation conditions, get oxygenated in the process of formation? If not, how long would it take for them to get oxygenated to levels sufficient for aerobic microbes? For instance could the Phoenix leg droplets have taken up enough oxygen for aerobic respiration by microbes?

Stamenkovi?: Just like the answer above. Dynamics is still to be explored. (But this is a really good question ?).

Wikinews also asked Stamenkovi? how their research is linked to the recent discovery of possible large subglacial lake below the Martian South Pole found through radar mapping.

((WN)) Some news stories coupled your research with the subglacial lakes announcement earlier this year. Could the oxygen get through ice into layers of brines such as the possible subglacial lakes at a depth of 1.5 km?

Stamenkovi?: There are other ways to create oxygen. Radiolysis of water molecules into hydrogen and oxygen can liberate oxygen in the deep and that O₂ could be dissolved in deep groundwater. The radiolytic power for this would come from radionuclides naturally contained in rocks, something we observe in diverse regions on Earth.

((WN)) And I’d also like to know about your experiment you want to send to Mars to help with the search for these oxygenated brines.

Stamenkovi?: We are now developing at “NASA/JPL-California Institute of Technology” a small tool, called TH2OR (Transmissive H2O Reconnaissance) that might one day fly with a yet-to-be-determined mission. It will use low frequency sounding techniques, capable of detecting groundwater at depths down to ideally a few km under the Martian surface, thanks to the high electric conductivity of only slightly salty water and Faraday’s law of induction. Most likely, such a small and affordable instrument could be placed stationary on the planet’s surface or be carried passively or actively on mobile surface assets; TH2OR might be also used in combination with existing orbiting assets to increase its sounding depth. Next to determining the depth of groundwater, we should also be able to estimate its salinity and indirectly its potential chemistry, which is critical information for astrobiology and ISRU (in situ resource utilization).

((WN)) Does your TH2OR use TDEM like the Mars 94 mission — and will it use natural ULF sources such as solar wind, diurnal variations in ionosphere heating and lightning?

Stamenkovi?: The physical principle it uses is the same and this has been used for groundwater detection on the Earth for many decades; it’s Faraday’s law of induction in media that are electrically conducting (as slightly saline water is).

Stamenkovi?: However, we will focus on creating our own signal as we do not know whether the EM fields needed for such measurements exist on Mars. However, we will also account for the possibility of already existing fields.
