A fire on Sunday night in the seven-storey carpark for the Echo Arena in Liverpool, England destroyed almost all the vehicles parked inside and led to cancellation of the final evening of the Liverpool International Horse Show and evacuation of nearby blocks of flats. The blaze reportedly started with a parked Range Rover Discovery.

Investigators with the fire brigade stated that they believe the fire began with an accidental engine fire in the Range Rover at about 4.30 pm. The first call was made at 4.42 and firefighters arrived eight minutes after that. Ultimately twelve engines and 85 firefighters were involved in combatting the blaze. Aerial appliances were used and also three high-volume pumps. Fed by the fuel in vehicles parked inside, the temperature of the fire in the carpark is believed to have reached as high as 1,000°C. It was too hot to be extinguished with water from hydrants, so a high-volume pump was used to draw water from the River Mersey, and two more were brought from other fire brigades in the region.

The carpark has seven storeys and a capacity of 1,600 vehicles, and approximately 1,300 were parked in it when the fire broke out. According to Dan Stephens, chief fire officer for Merseyside Fire and Rescue Service, almost all of them were destroyed, with the exception of a few parked on the top level and at corners. “With these very high temperatures, you were never going to put the fire out without the whole building taking hold. The speed at which the fire spreads means you simply aren’t going to put it out,” said Stephens.

The carpark itself was severely damaged; according to Joe Anderson, the mayor of Liverpool. It is not in danger of collapsing but will have to be demolished, which will be difficult with the many burned-out cars still inside it, Anderson told the BBC.

According to Stephens, there were no serious injuries: one woman injured her hand, and two people were treated for smoke inhalation. A spokesman for the Echo Arena also stated that all animals were safe. All horses were successfully evacuated from the carpark and then removed from the stables after smoke spread to them. Six dogs were also rescued unharmed, two on a lower level in the early stages of the fire and four that had been left in a car on the top level, freed by firefighters on Monday after the fire was put out.

The final evening of the four-day Liverpool International Horse Show had been scheduled to begin at 7.30, and had to be cancelled. Many attendees were stranded in the city on New Year’s Eve night. Merseyside police directed people to the Pullman Hotel, where Red Cross assistance was available, and the Liverpool City Council set up an assistance centre at the Lifestyles Gym. A spokesman for the Association of British Insurers has said that insurance companies will “move very quickly” to reimburse owners whose vehicles were destroyed.

Nearby blocks of flats were evacuated because of the smoke. Eyewitnesses reported hearing what they at first thought were firecrackers, then “multiple explosions”, “bangs and popping”, “the bangs of car windows exploding”. People reported leaving everything in their cars, including their cellphones, and running for their lives.

Mayor Anderson tweeted that cuts to fire services over the last two years made it significantly harder to fight the fire and might have caused it not to be controllable. He also suggested that fire safety in multi-storey carparks had not been sufficiently considered and that installing sprinklers in them might help stop future fires before they become unmanageable, in a letter to Nick Hurd, a member of Parliament.

At Thanksgiving dinner David Shankbone told his white middle class family that he was to interview Reverend Al Sharpton that Saturday. The announcement caused an impassioned discussion about the civil rights leader’s work, the problems facing the black community and whether Sharpton helps or hurts his cause. Opinion was divided. “He’s an opportunist.” “He only stirs things up.” “Why do I always see his face when there’s a problem?”

Shankbone went to the National Action Network’s headquarters in Harlem with this Thanksgiving discussion to inform the conversation. Below is his interview with Al Sharpton on everything from Tawana Brawley, his purported feud with Barack Obama, criticism by influential African Americans such as Clarence Page, his experience running for President, to how he never expected he would see fifty (he is now 53). “People would say to me, ‘Now that I hear you, even if I disagree with you I don’t think you’re as bad as I thought,'” said Sharpton. “I would say, ‘Let me ask you a question: what was “bad as you thought”?’ And they couldn’t say. They don’t know why they think you’re bad, they just know you’re supposed to be bad because the right wing tells them you’re bad.”

Chemists modeling the structure of strongly acidic solutions have found that hydronium ions can associate into unusual ion pairs.

Hydronium ions form whenever an acid dissolves in water, but it had always been assumed that they would repel each other. This new work suggests that at certain concentrations a fraction of the hydronium ions can in fact pair up.

Gregory A. Voth and Sergei Izvekov of the University of Utah, in collaboration with Feng Wang of Boston University, were examining the structure of highly acidic solutions (pH 0 to 1) of hydrochloric acid using sophisticated computer modeling. It is known that in water such acids dissociate into positive ions (cations) and negative ions (anions), with the H⁺ part solvated by water molecules to form cations such as hydronium (H₃O⁺). It might be expected that positive ions such as these would repel one another, but it turns out that some of these cations unexpectedly associate into pairs at acid concentrations of 0.43 – 0.85 M . The pairing disappears at even higher concentrations where larger aggregates of cations and anions instead begin to form. The authors note that “cation pairs are stabilized by a nonclassical charge delocalization of the excess proton charge defects over multiple water molecules”. They explain the phenomenon in terms of the amphiphilic nature of the hydronium ion discovered in their 2004 work.

Recent work by Wallace et al. indicated the presence of hydronium ion pairs in crystals, but this is the first time such an association has been predicted for an aqueous solution.

The Canadian Food Inspection Agency (CFIA) has issued border alerts for specific protein ingredients, imported from China, that may be incorporated into products destined for human consumption.

Inspectors from the Canada Border Services Agency (CBSA) will hold products, such as wheat and corn gluten, as well as soy and rice proteins until they can be tested for melamine, the contaminant found to have sickened pets through its use in pet food. If determined to be free of melamine, the ingredients will be released to the intended recipient. Materials such as glutens and protein powders are used commonly in many forms of food products.

The CFIA said it was not acting on specific information, but rather taking a cautious approach to human protection. “That’s why we have the border lookout for the ingredient, so that we can proactively assess any potential that the product is contaminated,” Paul Mayers of the CFIA told CBC News.

Since the border alert for melamine is a new procedure, the government can’t be sure if the contaminant made it into the food chain previously. The CFIA acknowledged that the same Chinese company under suspicion in the tainted pet food affair had shipped wheat gluten to a Canadian company, which in turn used it in food for fish farms. Although the fish were subsequently eaten by people, the CFIA believes the health risk from such consumption would be low.

In related news, Canadian researchers at the University of Guelph believe they may have determined the mechanism of how melamine caused illness in cats and dogs.

Both cyanuric acid and melamine were found in urine samples from pets that died after consuming contaminated pet food. The two compounds react with one another to form crystals that may block kidney function, researchers at the university said. The researchers observed crystals formed in cat urine by the addition of melamine and cyanuric acid. The composition of these crystals matches those found in the urine of affected pets when compared by infrared spectroscopy (FTIR).

“You wouldn’t normally expect to find those compounds in pet food, and hence nobody was really looking for it,” said John Melichercik, director of analytical laboratory services. “It’s just another piece of the puzzle along the way in this particular pet-food issue.”

On Sunday, female ice hockey players from North and South Korea joined one another for a training session before the upcoming Winter Olympics. Players from the two Koreas are to compete together as a united team for the events hosted in Pyeongchang, South Korea, which are scheduled to start on February 9; Seoul’s Unification Ministry said. The cross-border gesture is part of diplomatic efforts to ease tensions on the divided Korean Peninsula and the team was approved by the International Olympic Committee.

The International Olympic Committee selected Pyeongchang in 2011 to host the event, marking South Korea’s first opportunity since the 1988 Summer Olympics in Seoul. The earlier event was marred by violence as North Korea had bombed a South Korean flight several months prior, killing over 100 and boycotted the event. Inter-Korean relations have changed considerably in the ensuing thirty years, including the two sending unified teams for table tennis and youth football in other non-Olympic competitions.

The announcement that the two countries would compete together was a stated goal of South Korean President Moon Jae-in. Last year, he announced the proposal and the two nations went into discussion this month. After two weeks, they made the announcement to field a consolidated 35-strong team of ice hockey players and have joint skiing exercises with both team coaches involved.

According to Yonhap News Agency estimates, about 80% of South Koreans support dialogue, but the move to have a joint team has been controversial. Over 10,000 South Korean citizens sent a petition to South Korean President Moon opposing the union and a group of North Korean defectors held a protest at the South Korean National Assembly on January 24, tearing apart photos of the North Korean leader, Kim Jong-un. Public support for eventual reunification of the Korean peninsula has waned in recent years, with the younger generation more skeptical of the possibility.

This week Google’s on-line video sharing website YouTube launches its own awards ceremony. The site will present the best user-generated videos posted during 2006 in seven categories. The starting point is Monday and users will end voting on Friday. Winners will get their trophies on March 26.

The categories that YouTube is going to present include: most creative or inspirational video, best series, as well as music video or commentary and best comedy. The last category, number seven, is called “most adorable video ever” and it is to continue the tradition of videos starring cats and dogs while asleep.

Those that are nominated are able to promote themselves on YouTube during the following five days. These users are also able to plead for votes.

The $1.65 billion Google’s acquisition gathered a huge number of fans. According to Jamie Byrne, head of YouTube product marketing, 2006 was a pioneering year for sites that rely on user’s content.

However, companies like Viacom, believe one category is missing – “Best Professionally Produced Copyrighted Video.” Last week Viacom sued Google together with YouTube for more than $1 billion. The lawsuit states that the ever increasing popularity of YouTube is due to a massive uploads of copyrighted videos including “The Colbert Report” and “South Park“.

At least six miners are trapped approximately 1700 feet underground in a coal mine in Utah after portions of the shaft collapsed. The mine is owned by Utah American Energy and is close to the town of Huntington, Emery County, 160 km south of Salt Lake City.

Robert Murray, The CEO, President, Director and owner of Murray Energy and the owner of Utah American Energy, said during a press conference at 5:00 p.m. (eastern time), an “earthquake caused the collapse at about 3:00 a.m. (mountain time).”

The United States Geological Survey (USGS) recorded what is allegedly a magnitude 3.9 earthquake at 2:48 a.m. (mountain time) on Monday morning 21 km (13 miles) east, southeast of Mount Pleasant, Utah, but the director of the USGS seismology stations Walter Arabasz, says that no earthquake caused the collapse.

Murray states that at least “two mining machines will be brought in to clean out the debris” at the beginning of the collapse and that he will “spare no expense” in rescuing the men.

“We have four rescue teams working to free the trapped miners. We will try four ways to get to the miners which include drilling 1,700 feet from the top of the mountain. We will also drill a hole” in a neighboring mine shaft sealed in 2004 after it was finished being mined that is “about 100 feet from the miners.”
