A paste containing synthetic tooth enamel can seal small cavities without drilling. Kazue Yamagishi and colleagues at the FAP Dental Institute in Tokyo say that the paste can repair small cavities in 15 minutes.

Currently, fillers don’t stick to such small cavities so dentists must drill bigger holes. Hydroxyapatite crystals, of which natural enamel is made, bond with teeth to repair tiny areas of damage.

Yamagishi and colleagues have tested their paste on a lower premolar tooth that showed early signs of decay. They found that the synthetic enamel merged with the natural enamel. The synthetic enamel also appears to make teeth stronger which will improve resistance to future decay. As with drilling, however, there is still the potential for pain: The paste is strongly acidic to encourage crystal growth and causes inflammation if it touches the gums.

The paste is reported in the journal Nature.

The name Robert Cailliau may not ring a bell to the general public, but his invention is the reason why you are reading this: Dr. Cailliau together with his colleague Sir Tim Berners-Lee invented the World Wide Web, making the internet accessible so it could grow from an academic tool to a mass communication medium. Last January Dr. Cailliau retired from CERN, the European particle physics lab where the WWW emerged.

Wikinews offered the engineer a virtual beer from his native country Belgium, and conducted an e-mail interview with him (which started about three weeks ago) about the history and the future of the web and his life and work.

Wikinews: At the start of this interview, we would like to offer you a fresh pint on a terrace, but since this is an e-mail interview, we will limit ourselves to a virtual beer, which you can enjoy here.

Robert Cailliau: Yes, I myself once (at the 2nd international WWW Conference, Chicago) said that there is no such thing as a virtual beer: people will still want to sit together. Anyway, here we go.

British fashion designer Alexander McQueen has died at the age of 40. He was found dead inside his residence in London, England yesterday.

The Metropolitan Police said they are not treating the death as suspicious. A spokesperson for the police force said, “[w]e were called by London Ambulance Service at about 10.20am this morning to reports of a man found dead at an address in Green Street, W1. He is believed to be 40 years old and from London. Next of kin have been informed, however we await formal identification before releasing the name of the deceased.” According to reports, McQueen committed suicide by hanging, however this has not been confirmed.

Between the years of 1996 and 2003, McQueen received Fashion Designer of the Year four times. He was also given a CBE by Queen Elizabeth II in 2003. The fashion designer had a new selection of clothing, entitled “McQ”, that was expected to be shown on Thursday; the show has now been cancelled. Alexander’s mother Joyce died earlier this month. In response to this, McQueen placed a message on his Twitter page which said “RIP mumxxxxxxxxxxxxxxxxxxxxxxxxxxx.” Isabella Blow, who assisted in making McQueen famous, killed herself in 2007.

Yesterday, a statement was released from McQueen’s company headquarters stating “On behalf of Lee McQueen’s family, Alexander McQueen today announces the tragic news that Lee McQueen, the founder and designer of the Alexander McQueen brand, has been found dead at his home. At this stage it is inappropriate to comment on this tragic news beyond saying that we are devastated and are sharing a sense of shock and grief with Lee’s family. Lee’s family has asked for privacy in order to come to terms with this terrible news and we hope the media will respect this.”

Pittsburgh, Pennsylvania — Local caterers get ready for big business, as almost three thousand fans converge on the David L. Lawrence Convention Center over the Independence Day weekend for the world’s largest ever furry convention, Anthrocon 2007.

Many hope to renew acquaintances, or meet new friends. Others look to buy from dealers and artists, or show off new artwork or costumes. Some attend to make money, or even learn a thing or two. But one thing unites them: They’re all there to have fun.

On the second day today of a three day visit to India the President of the People’s Republic of China, Xi Jinping, has signed multiple economic deals with India’s Prime Minister Narendra Modi.File:Xi Jinping October 2013 (cropped).jpg

China would set up two industrial parks in India, one in Gujarat and one in Maharashtra. The deals encompass Chinese investment of US$20 billion in infrastructure projects, modernisation of the Indian Railways, and agreements on trade, space exploration, and civil nuclear energy. China has also committed itself to opening its markets to Indian pharmaceuticals and farm products. A final settlement of the unresolved dispute over the Chinese–Indian border in the Himalayas is also to be sought; the dispute, over which the Sino-Indian War of 1962 was fought, arises over where the border should be.

In a message to Chinese journalists on Tuesday, Indian Prime Minister Modi used the slogan “Inch towards Miles”, (standing for “India and China towards Millennium of Exceptional Synergy”) to express his hopes as to the future direction of the two nations’ bilateral ties. The Indian Prime Minister further emphasised the shared history and culture of the two nations which could be further enhanced for a brighter shared future.

The Chinese president’s visit comes amid tension over Chinese territorial claims in the South China Sea, clashing with claims of several other countries, including Japan. In a five day visit to Japan in the beginning of this month, Modi said “The world is divided in two camps. One camp believes in expansionist policies while the other believes in development.” Modi and Japanese Prime Minister Shinzo Abe also came to an agreement which would see Japanese investment in India rise to US$33.6 billion in the next five years.

Another unresolved tension between the two nuclear powers India and China is continued Chinese support of India’s rival Pakistan.

Xi’s visit to India, which began yesterday following visits to Sri Lanka and the Maldives, is part of an initiative Xi likens to the creation of a 21st Century Maritime Silk Road.

In an effort to ease complaints by the U.S. and Europe about a heavy influx of low priced Chinese goods, China will raise export tariffs on 74 categories of textile products in June. This follows plans from the U.S. to impose quotas on Chinese textiles and clothing.

Products likely to see an increase from the Chinese move include synthetic fiber shirts, trousers, knit shirts and blouses, cotton shirts, and combined cotton yarn. Last week, similar restrictions were imposed by the U.S. on cotton trousers, knit shirts, and underwear. Currently, a 2.5 cent charge per item is imposed; the new tariff will raise this to the equivalent of 12 cents per piece now. While this is a fourfold increase, it is not expected to affect consumer prices. Because of this, some doubt the tariff will have any effect on correcting the trade imbalance.

This move is in response to U.S. trade quotas imposed due to concerns that increased Chinese goods would put U.S. textile manufacturers out of business. According to Auggie Tantillo, executive director of the American Manufacturing Trade Action Coalition, a textile industry group in the U.S., the move will preserve 10,000 U.S. jobs. The new U.S. trade quota will limit the growth of Chinese textile imports to 7.5 percent compared with shipments over the past year.

Prior to January 1, a global quota system helped regulate the trade. With the quota system gone, fears have arisen that a flood of Chinese goods could undercut U.S. competitiveness in the market. China is able to market its goods cheaply due to an artificially weak yuan. The U.S. Treasury criticized the China yuan policy as “highly distortionary”, posing a major risk to China’s economy itself and to global economic growth. They challenged China to revalue its currency to bring it to a level they believe will allow fairer competition between global manufacturers.

China has disputed the charges of the U.S. Treasury. Chinese Commerce Minister Bo Xilai said, “I believe they are not reasonable”.

Laura Jones, a representative of large retailers, also criticized the move, saying “These restrictions on imports from China will do absolutely nothing to help the U.S. textile industry — and the government knows it.”

China has seen a boom in economic growth in recent years due to growing trade surpluses with the West, but economists worry that the trade gap will cause longer term global economic problems. China’s textile and apparel exports are the most noteworthy example, with exports up over 1,000 percent in some categories this year and the rapid loss of marketshare and jobs by U.S. textile manufacturers.

Beginning in 1978, the Chinese economy has been transforming from a Soviet-style centrally planned economy to more of a free market style system, under the rigid political control of Communist Party of China.

To this end, the government has leveraged foreign trade to stimulate economic growth. The result has been a fourfold increase in GDP, making China the sixth largest economy in the world. By 2012 the People’s Republic of China may have the highest GDP in the world.

According to U.S. statistics, from 1999 to 2004 China’s trade surplus with the U.S. doubled to $170 billion. Wal-Mart is China’s seventh largest export partner, just ahead of the United Kingdom.

However, the gains from their “socialist market economy” have not been without problems. The Chinese leadership has often experienced the worst results of socialism and capitalism: bureaucracy, lassitude, corruption, and inflation. Inflation rates have been an on-going challenge, reaching as high as 17% in 1995.

Environmental deterioration is a longer-term threat to economic growth. In 1998, the World Health Organization reported that China had seven of the 10 most-polluted cities on Earth. Another concern among some economists is that China’s economy is over-heating, and due to its global economic expansion this could have major repercussions among other nations.

Typically, wages have been low and working conditions poor, with workers living in restrictive dormitories and working at boring factory jobs. However, recent labor shortages have started improving conditions, and raising the minimum wage towards the equivalent of 100-150 US dollars per month. The labor shortages are in part a result of a demographic trend caused by strict family planning.

The Marussia F1 team’s test driver, Spaniard María de Villota, was taken to hospital by air ambulance today after a collision in testing at Duxford Aerodrome.

At the end of her first installation run, the car she was driving had a low-speed collision with the loading ramp of the team’s support truck. According to BBC Cambridgeshire presenter Chris Mann, the car “suddenly accelerated” into the rear of the vehicle. The Marussia team released a statement an hour and a half after the accident, stating that she had been transferred to hospital, and a further statement would be issued once her condition had been assessed.

A spokesman for the East of England ambulance service, Gary Sanderson, said de Villota had “[…] sustained life-threatening injuries and following treatment at the scene by paramedics, she has been taken to Addenbrooke’s Hospital for further care.” According to witnesses, she was motionless for about fifteen minutes as medical teams attended to her, but did move her hands before being taken away from the test track. Medical charity Magpas, whose volunteer paramedics attended the accident, reported she had sustained injuries to her head and face, and was in a ‘stable condition’ when she reached the hospital.

Marussia reported her as conscious later in the afternoon: “Since Maria’s arrival at the hospital at approximately 10.45am this morning, she has been receiving the best medical attention possible at the hospital, which is the region’s major trauma centre. Maria is conscious and medical assessments are ongoing. The team will await the outcome of these assessments before providing further comment. The team’s first priority at this time is Maria and her family.”

De Villota was announced as Marussia’s test driver in March, having prior experience driving for Alan Docking Racing in Superleague Formula in Spain.
