Los Angeles, California —A simple saliva test can predict whether children will get cavities, how many cavities they will get and which teeth are most vulnerable.

Developed by researchers at the University of Southern California in Los Angeles, the test quantifies the genetic component of tooth decay, spotting the risk when something can be done about it.

“When we apply this to young children, it allows us to predict what might be their future caries history—the number of cavities that they’ll get by, say, their late 20s or early 30s,” says researcher Paul Denny.

Called the Caries Assessment and Risk Evaluation (CARE) test, the test measures the relative proportions in saliva of different types of sugar chains called oligosaccharides. The same sugar chains are present on tooth surfaces.

The effect of sugar chains on teeth’s resistance to disease is analogous to the effect of “good” and “bad” cholesterol on blood vessels. “Good” sugar chains tend to repel bacteria that cause cavities while “bad” allow bacteria to bond to teeth and start the decay process. Unlike cholesterol, however, sugar chain makeup in humans is 100% genetically determined.

Denny and colleagues have found that the sugar chain makeup in saliva can predict a child’s future cavity history to plus or minus one cavity with greater than 98% confidence.

The findings suggest that in developed areas of the modern era genes play a more significant role in tooth decay than in former times or third world nations where gross malnutrition and negligent oral hygiene held the greatest impact on dental health.

This past Sunday, Illinois Governor Pat Quinn signed into law a bill known as “Rocky’s Law” that requires Illinois high schools, through the local school district, to buy catastrophic injury insurance up to US$3 million or medical costs for up to five years, whichever one comes first, that covers student athletes. The insurance must cover student athletes while they are competing.

The legislation was named after Rasul “Rocky” Clark. In 2000, the Eisenhower High School football player became paralyzed from the waist down as a result of a tackle during a game. His school based health insurance covered the costs of his medical treatment. A legislator sponsoring the bill noted that the need for this type of insurance is rare. Clark’s mother attended the legislation signing. Her son died last year.

Before parents can claim money from school insurance, they first must pay out US$50,000. Schools have until January 1, 2014 to comply with the law. Schools cannot charge students more than US$5 to defray the cost of insurance. If a school district already requires student to be covered through private health insurance, they are exempted from this law.

Former U.S. Commissioner of Internal Revenue Mark Everson took some time to talk with Wikinews about his campaign for the U.S. Republican Party’s 2016 presidential nomination.

Everson served as Commissioner of Internal Revenue, the administrative head of the Internal Revenue Service (IRS) from 2003 to 2007, during the George W. Bush administration. After his departure, he briefly served as CEO of the American Red Cross, worked in the cabinet of Indiana governor Mitch Daniels, and worked for the tax consulting firm alliantgroup. He announced his candidacy this past March with a sixteen-page open letter in which he outlined the six pillars of his campaign: amnesty for illegal immigrants, reinstatement of the military draft, a promise to serve only a single presidential term, and calls for tax reform, deficit reduction, and corporate responsibility.

He was excluded from the August 6 Fox News Republican presidential debate and has been excluded from most presidential polls. However, he is listed on the Republican Party’s website as one of 18 candidates and filed a Federal Election Commission (FEC) complaint against Fox News for his exclusion from the August 6 debate.

With Wikinews reporter William S. Saturn?, Everson discusses his 2016 campaign, the media blackout of his campaign, and his views on the presidency and the possible Everson administration.

Do you have a hard time finding a parking space? Take the bus or tram if you go to the city. That’s the message Belgian bus company De Lijn (The Line) is sending to promote public transport as a solution for car parking problems. As a part of their media campaign, they have jokingly suggested that people use the top of the busses as parking space.

Another idea they are using in their media campaign: maybe you could park your car on the bottom of a canal? The bus company is using an invented diving company called Cardive, which has divers that offer to dump your car in the canal. The divers walk around in cities and hand out free bus tickets and maps of the bus network.

To reach car drivers who are not using public transport, the media campaign has several radio commercials that present other solutions to the car parking problem. You could use “asphalt-spray” to camouflage your car, making it invisible for policemen (although you then need to remember where you’ve parked). Or you could use the “flat tire kit”, which comes with a fake flat tire and an inflatable dummy, so it looks like you’re replacing your flat tire. The final idea the bus company has is to use a View-Master to fool parking guards into believing that your car has been stationed correctly.

A survey among 4000 customers of De Lijn shows that two out of three car owners who use public transport, do so to avoid parking space troubles, and in cities this percentage rises to 90%. The survey further shows that 39% use the bus to go shopping.

During the month of May, the auto-bus and the divers tour several cities in Flanders (Leuven, Hasselt, Ghent, Bruges and Antwerp).

Investigators examining the wreck of British Airways Flight 38, a Boeing 777 that crash landed short of the runway at London’s Heathrow Airport in the first hull loss of a 777, are examining the aircraft’s fuel system as a possible factor in the crash. No-one was killed as the scheduled flight from Beijing, China lost power during final approach on January 17.

136 passengers and 16 crew were on board when power was lost to the two Rolls-Royce engines about two miles from the runway, at a height of 600 feet. Autopilot and autothrottle were engaged at the time, the latter having just commanded an increase of thrust to the engines when power was lost. Co-pilot John Coward, in control at the time, was subsequently praised for being able to glide the disabled plane to within 1,000 feet of the runway, clearing a number of houses along the way.

Subsequent investigation has revealed that not only did the engines not fail simultaneously, but neither failed completely, contradicting initial belief. A preliminary report by the United Kingdom’s Aircraft Accident Investigation Branch (AAIB) stated that after the autothrottle commanded more thrust “The engines both initially responded but after about 3 seconds the thrust of the right engine reduced. Some eight seconds later the thrust reduced on the left engine to a similar level… Both engines continued to produce thrust at an engine speed above flight idle, but less than the commanded thrust.” This situation prevailed until impact.

On Wednesday the AAIB stated that they were examining “All possible scenarios that could explain the thrust reduction and continued lack of response of the engines.” However, it also went on to specifically mention attention to the jet’s fuel system, saying “This work includes a detailed analysis and examination of the complete fuel-flow path from the aircraft tanks to the engine-fuel nozzles.” The AAIB also ruled out the plane having completely run out of fuel, stating that there was “adequate fuel” in the tanks when the plane crashed. In addition to the fuel required to get to the target destination or emergency alternative airport – whichever is further – aircraft typically carry between thirty and forty-five minutes worth of extra fuel as a safety margin.

Possible scenarios being examined include fuel contamination, coming either from fuel taken on at Beijing or leakage from an unknown source. In particular, a heavy contaminant at the bottom of the tanks would explain a lack of earlier problems on the flight, as the fuel levels would only have become low in the final stages of the trip. Another possibility is that a central part of the fuel system developed a leak, reducing the amount of fuel available to the engines.

It is known that, according to the AAIB, “the autothrottle and engine-control commands were performing as expected prior to, and after, the reduction in thrust,” suggesting that all software in the aircraft was functioning correctly and rendering a software failure unlikely, although this possibility also remains under investigation.

The Supreme Court of the United States on Wednesday April 18 has upheld the federal Partial-Birth Abortion Ban Act of 2003. The 5-4 vote reflected the change in vote count resulting from the retirement of Justice O’Connor and the confirmation of Chief Justice Roberts and Justice Alito.

The Intact dilation and extraction procedure, also known as partial birth abortion, involves removing an intact late-term fetus from the womb via the cervix. While it is a relatively rare operation – 0.17% of all abortions in the US in 2000, it has become a focal point in the abortion debate.

The Partial-Birth Abortion Ban Act bans the procedure in cases where the fetus is terminated during the operation, unless it is performed to to save the life of the mother.

Justice Kennedy wrote in the opinion of the court: “respondents have not demonstrated that the Act would be unconstitutional in a large fraction of relevant cases.” Further, he said, “Respondents have not demonstrated that the Act, as a facial matter, is void for vagueness, or that it imposes an undue burden on a woman’s right to abortion based on its overbreadth or lack of a health exception. For these reasons the judgments of the Courts of Appeals for the Eighth and Ninth Circuits are reversed.”

In a concurring opinion, Justice Thomas stated that he joins “the Court’s opinion because it accurately applies current jurisprudence, including Planned Parenthood of Southeastern Pa. v. Casey, 505 U. S. 833 (1992).”

In dissent Judge Ginsburg wrote: “Today’s decision is alarming. It refuses to take Casey and Stenberg seriously. It tolerates, indeed applauds, federal intervention to ban nationwide a procedure found necessary and proper in certain cases by the American College of Obstetricians and Gynecologists.”

Justice Kennedy’s words also recall the complicated issues of standing related to such cases. An issue in Roe v. Wade was the impossibility of any individual having standing in a court proceeding regarding abortion rights, since court proceedings take more than the 9 months of pregnancy, retiring any individual plaintiff’s standing before an appeals process can take place. The criterion of “a large fraction of relevant cases” may effectively deny standing to any plaintiffs who wish to litigate particular restrictions in some relevant future cases.

Rail services between Melbourne and Adelaide in Australia are expected to be disrupted until early next week following a fatal crash between a truck and freight train in Lismore, Victoria 170 Km (105 miles) South-West of Melbourne.

The B-Double truck hit the side of a 1,375 metre long freight train at a level crossing at 7:13 a.m. AEST on Thursday in heavy fog, derailing two locomotives and 44 goods wagons. Victorian police said that the truck had been wedged beneath the wreckage of the train.

The driver of the truck, thought to be a 34-year-old man from Wedderburn in Victoria’s North-West died in the crash. The train driver and an observer escaped uninjured. Police said it could take a number of days to retrieve the truck driver’s body. “It could possibly take days to retrieve the body” a Victorian police spokesperson said.

Great Southern Railways, which operates “The Overland” passenger train service between Melbourne and Adelaide said it expected rail services to be disrupted up until early next week. The company will transfer passengers to bus services or allow them to claim a full refund.

The crash will also disrupt freight services between Melbourne and Adelaide.

Local residents and the Victorian opposition are blaming the crash on the level crossing itself, which has no booms, lights or bells.

Rob Dennis, a local resident said the level crossing is the cause of the crash, as it is not fitted with boom gates or flashing lights.

“And it’s a blind turn for anything in a large vehicle,” he said.

Terry Mulder, the opposition’s transport spokesperson said the Bracks Government should have spent part of the $750 million allocated to fast rail projects to upgrading level crossings in Victoria.

“The State Labor Government has wasted $750 million on fast rail projects,” Mr Mulder said.

Mr Mulder said that Victoria has 2,274 level crossings, 1,468 which have no warning systems in place.

The US Secret Service has released the first photos Wednesday of the new presidential limousine that will transport Barack Obama down Pennsylvania Avenue next Tuesday as part of the 56th Presidential inaugural parade after he is sworn in at the Capitol. The First Limo – the 2009 Cadillac Presidential Limousine – will replace President Bush’s Cadillac DTS Presidential Limousine that rolled out in 2004.

Nicknamed “The Beast”, the hulking machine is a new model year 2009, modified limousine. According to General Motors, the new “2009 Cadillac Presidential Limousine” is the first not to carry a specific model name. The Obama Mobile was introduced on January 14 with noticeably different styling borrowed from the Cadillac Escalade and STS, while the suspension is most likely related to the Chevrolet Kodiak medium-duty truck.

Mr. David Caldwell of General Motors has revealed that the sleek black car would include a hand-crafted interior and “state of the art electronics.” The car’s high-tech security features include five-inch-thick (12.7-centimeter-thick) bombproof glass, tough-as-nails tires, and a sealed interior that’s invulnerable to chemical attack. The armoured limousine has been heavily modified to withstand potential attacks by weapons or bombs. The San Francisco Chronicle puts it in a proper perspective noting, “a half-inch of transparent armor is enough to stop a .44 Magnum round at point-blank range; at a thickness of 1 1/4 to 1 1/2 inches, the same material can withstand higher-velocity bullets fired from military assault rifles.”

According to spy photographer, Brenda Priddy, and General Motors, the limousine, which has the intricate, dual-textured grille, is also equipped with standard Goodyear Regional RHS truck tires in a 285/70R19.5 size, on 19.5-inch wheels. The rims have a run-flat device (manufactured by Hutchinson Industries). Xenon headlights from the Escalade are installed in the front, while the rear has some STS part. The doors are at least 20 centimeters (8 inches) thick. It carries the US flag on the front fenders and an embroidered Seal of the President of the United States is affixed to several panels in the back.

According to the US Secret Service, the vehicle would be a “valuable asset” in providing the President with the highest level of protection. “Although many of the vehicle’s security enhancements cannot be discussed, it is safe to say that this car’s security and coded communications systems make it the most technologically advanced protection vehicle in the world,” Nicholas Trotta, Assistant Director for the Office of Protective Operations said in a statement. The new limousine is the responsibility of White House Transportation Agency.

The Presidential State Car is the official state car used by the President of the United States. It is informally known as “Cadillac One”. The current Presidential State Car is a 2005 hand-crafted, armored, and stretched DTS (DeVille Touring Sedan) built on a GM four-wheel drive platform. It was first used on the second inauguration parade of George W. Bush in 2005. But the version to be used by President Obama uses a GMC Topkick chassis, while maintaining the Cadillac exterior.

The President of the United States travels in one of two armoured Cadillac limousines based upon the normal sedan, the Cadillac DTS, with heavy customisation. Lincoln cars have also been used in the past, most notably by President John F Kennedy. The current limousines were custom-built by O’Gara, Hess and Eisenhart, founded in Fairfield, Ohio in 1942. It specializes in armouring limousines for presidents and heads of state.

President William McKinley was the first US president to ride in an automobile. However, it was President Theodore Roosevelt who rode on the first government-owned car, a white Stanley Steamer. Roosevelt’s successor, William Howard Taft, was the first president to use a presidential state car that was permanently stored in the White House garage.

Meanwhile, Obama’s 2005 Chrysler 300C Hemi was auctioned on eBay with a starting bid of $100,000 and a buy-it-now price of $1,000,000. It has less than 21,000 miles on it and is in like-new condition. He leased the car in 2004 and traded it for a Ford Escape Hybrid in 2007. The car was sold to Tim O’Boyle.
