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.

At least 10,000 protesters stormed government buildings, burnt down a police station, and took control of an airport to prevent reinforcements from being flown into Jalal-Abad, Kyrgyzstan today as they demanded the resignation of president Askar Akayev. The protesters claim that recent parliamentary elections were rigged.

According to a police source in the capital of Bishkek, four police were beaten to death in clashes with protesters.

Last week, Akayev warned civil war would break out if there was an attempt to copy the Ukrainian “Orange Revolution.” However, the government says it wants a peaceful resolution. “We have never gone against our own people, especially not with weapons in our hands,” Prime Minister Nikolai Tanayev said.

Opposition leader Kurmanbek Bakiyev says negotiations will only be fruitful if president Akayev himself is involved. “All other lower level negotiations will be just a waste of time,” Bakiyev said.

The U.S. state department issued a statement saying the situation could be dealt with “according to the rule of law,” and spokesman Adam Ereli said, “U.S. officials have been in contact with both the government and opposition to reinforce this message.”

The OSCE stated the elections did not properly measure up to international standards, citing “lack of effective voter access to diverse sources of information, bias in the media, continued de-registration of candidates on minor grounds…, and inaccurate and poorly maintained voter lists.”

On December 4, 2008, a solar car, developed by scientists at Swiss universities, ended its journey of traveling around the world at the United Nations climate talks in Pozna?, Poland. Yvo de Boer, the Executive Secretary of the UN Framework Convention on Climate Change, rode into Pozna? in the vehicle, along with schoolteacher Louis Palmer.

The two-seat car began its journey 17 months ago in Lucerne, Switzerland. Carrying solar cells on a trailer, the car sent the message that global warming can be stopped and there are better alternatives.

“This is the first time in history that a solar-powered car has travelled all the way around the world without using a single drop of petrol,” said Palmer. “These new technologies are ready. It’s ecological, it’s economical, it is absolutely reliable. We can stop global warming.”

Many people have been carried by the solar car, including New York City Mayor Michael Bloomberg and UN Secretary General Ban Ki-moon.

The conference in Pozna? seeks to draft a new climate treaty that would replace the Kyoto protocol, which is set to expire in 2012. The delegates hope to finalize the treaty by December 2009, when the UN reconvenes on the climate in Copenhagen, Denmark.

“Here at the conference, we are talking about reducing emissions by 10 or 20 percent,” Palmer said. “I want to show that we can reduce emissions by 100 percent — and that’s what we need for the future.”

Greenpeace activists have scaled the house of Britain’s Deputy Prime Minister, John Prescott, and then mounted 60 square feet of solar panels on the roof.

The four men and four women were highlighting what they believe is Prescott’s failure to make new houses, for which he has responsibility, more energy efficient.

After putting the solar panels up, they unfurled a large banner which read Oi 2 Jags! Hit targets, not voters.

John Prescott’s wife was alone in the house when the protesters climbed the building. She was reportedly awoken by their noise.

One protester, Laura Yates, 27, said, “The Deputy PM’s got a reputation for straight-talking,” she said from the roof, “but since the election kicked off we’ve heard barely a squeak about climate change from big hitters like him. As long as the average existing British house is responsible for six tonnes of CO2 every year he’s not dealing with the climate crisis. He’s in danger of hitting more voters than climate targets. Whoever wins on May 5th needs to get serious about energy efficiency.”

Speaking from the roof by mobile phone, she told Reuters, “It’s a major contributor to the climate change problem and Prescott could do something about this, particularly with the millions of new homes that are going to be built in Britain over the next years,” she said.

“He’s overseeing this house building programme and he should be ensuring that every one of these new homes is built to zero emissions standards,” she added.

The protesters climbed down at 2.50pm and were promptly arrested by local police for “harassment of a person in a dwelling”. The police then handcuffed them before taking them away in a van. The protesters left the solar panels by the door of the house, offering to come back and install the panels at a later date.

A police officer emphasised to BBC News that the distress of the event had been immense for Mrs Prescott: “It’s not pleasant to be invaded in the privacy of your own home and it is being treated seriously. She’s very distressed but she’s pleased with the happy outcome.”

John Prescott is currently touring the country as part of Labour’s General Election 2005 campaign. Speaking from Gloucester, he told BBC News 24, “It’s now clearly a publicity stunt and it terrorised my wife in the early hours in the morning to see all those men scrambling over the building. [Mrs Prescott] did not know who they were. It’s deplorable and unacceptable even for a publicity stunt.”

The protesters were challenged by the armed police officers who guard Mr Prescott’s home, but reportedly the officers withdrew when they realised it was a peaceful protest.

On Tuesday, Indian Railway Minister D. V. Sadananda Gowda presented his first budget for Indian Railways.

The budget emphasized increased amenities for travelers, better safety, and timely completion of projects. There were no fare hikes announced as both passenger and freight fares had been increased last month. But, it was announced that fares will be revised twice a year to absorb fuel costs. Gowda criticized previous governments for announcing new projects and failing to complete them. He said projects will now be prioritized, such as decongesting major routes instead of announcing new ones. Gowda announced no major new projects, but announced 54 new trains. He also criticized the last government for driving the railways into a loss.

Gowda announced a bullet train between Mumbai and Ahmedabad; new semi-high speed trains in nine sectors connecting metros; and new measures towards improving cleanliness, food, and e-ticketing were announced. He said CCTVs will be installed in major stations to monitor cleanliness, and major stations will have food courts serving local cuisines and precooked food from reputable catering brands will be served on-board. The railways have faced complaints of substandard food in the past.

He announced the introduction of a new rail-flaw detection system to better investigate the causes of accidents. The budget allocated a significant sum to the construction of bridges at unmanned crossings, a major cause of rail-track deaths. He announced a new project to introduce automatic closing doors on mainline and suburban trains, and said wi-fi will be provided in larger stations and select trains. Workstations will be available for on-board use for a fee by Business travelers. The e-ticketing system will be extended from booking tickets to booking coaches and entire trains, and also retiring rooms in stations. Electric mobility carts will be provided to elderly and handicapped passengers at all major stations. Also, Railway Protection Force will recruit four thousand female constables and escorted carriages will be provided for women. A significant amount was announced for improving rail connectivity in north-east India.

Gowda emphasized use of public-private partnerships (PPPs) to fund future projects. He also said he will ask the Cabinet to approve foreign direct investment (FDI) in Indian Railways. Some stations are to be improved using PPPs. Manish R. Sharma, executive director of capital projects and infrastructure at PricewaterhouseCoopers, pointed out the budget didn’t contain any information on how the government intends to attract private investors. Deven Choksey, managing director at K. R. Choksey securities, said the government now seemed to be more inclined towards PPPs than before. India’s stock index SENSEX dropped and closed 2% below opening. Investors were observed selling shares in energy, infrastructure, and real estate sectors.
