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.

A National Academy of Sciences report (.pdf) last year said that while the milk and meat from cloned animals would not likely make anyone sick, more research should be performed. Now, a new US-Japan study published in the April 11 online issue of the Proceedings of the National Academy of Sciences says that milk and meat from cloned cattle does indeed appear to meet industry standards and appears to be safe for human consumption.

As BBC News reports, the scientists, led by Professor Jerry Yang from the University of Connecticut, compared the produce from two beef and four dairy clones, all derived from a single Holstein dairy cow and a single Japanese black bull, with the produce from normal animals of similar age and breed.

The meat was analysed against more than 100 physiological, tissue and cellular components, while the milk was analysed for protein, fat and other variables. No significant differences between the produce of cloned and normal cattle were found. Higher levels of fat and fatty acids were found in the cloned cow meat, but they still fell within beef industry standards.

While the study showed the cloned produce to be within the range approved for human consumption, the scientists stressed that the research was still in its early stages. Their findings, they said, provide “guidelines” for further research with larger numbers of clones from different genetic backgrounds.

Cloning livestock may one day increase yields by copying those animals that are especially productive and especially resistant to disease.

“The milking production levels in the US are three to four times higher than levels in China; maybe even five times or more compared to cows in India and some other countries,” Professor Jerry Yang told BBC News. “Therefore cloning could offer technology for duplicating superior farm animals. However, all the products from these cloned animals must be safe for human consumption. …and it is a major issue for scientists to provide a scientific basis for the data and information to address this question.”

As USA Today reports, there is currently no law governing the sale of meat or milk from the estimated 1,000 to 2,000 cloned farm animals in the USA. But since 2003, the US Food and Drug Administration (FDA) has asked producers to voluntarily keep the meat and milk of these animals, and that of their offspring, out of the food supply.

Wired News reports that companies like ViaGen and Cyagra, which offer livestock-cloning services, have also been waiting for several years for a final say from the FDA.

“For the United States agricultural industry, (cloning) can reduce the number of cows necessary for milking,” said Jerry Yang “They can have a pleasant environment and produce even more milk.” He also said that cloning cattle from the United States, where genetic breeding is more advanced, could save developing countries 50 years of breeding.

The idea of cloning animals for human consumption is not without its critics. First, there are the welfare concerns, as most cloned animals do not make it to term before being born, and many of those that do are born deformed or prone to illness. The Humane Society of the United States has asked for a ban on milk and meat from clones for just this reason. Second, there is still the concern that healthy clones may have subtle defects that could make their food products unsafe to eat.

As the Washington Post reports, some critics are asking why it is necessary to clone cows that produce huge amounts of milk when surpluses, rather than shortages, are the main problem facing the U.S. dairy industry today.

A viral election joke has landed several politicians in hot water as Norway goes to the polls to elect its parliament today. A hoax message turning voters away from polling stations is circulating in digital media. The message was also passed on by politicians, who have used social media like Twitter and YouTube to interact with the voters during the campaign. The targeted party is not laughing, and is warning that the activity could be seen as voter suppression.

“Due to full polling stations, Progress Party voters should send their vote by SMS [Standard Modular System] with shortcode FRP to 2009″ That message, and variations of it, was the joke circulating in social media such as Facebook and Twitter or by mobile phone messages.

Norway has taken significant steps towards e-government, such as a trial letting pre-calculated tax returns be filed by SMS. In this context, the General Secretary of the Progress Party, Geir Mo, said that the message was “sabotaging democracy”, because the damage would be done even if just one person believed the message. Kjell Ingolf Ropstad, one of the politicians who passed the message on, refused to apologize for doing it.

The main issue in the election has been whether voters should let the Labour Party dominated majority coalition government stay in power, or vote them out by voting for opposition parties.

Yesterday, Chinese Foreign Minister Wang Yi attended bilateral talks with Indian External Affairs Minister Subrahmanyam Jaishankar and National Security Advisor Ajit Doval.

Wang arrived in New Delhi Thursday night after visiting Pakistan and Afghanistan.

Wang discussed the recent Indo-China skirmish in Ladakh which led to the death of twenty Indian soldiers and four Chinese soldiers and showed interest to conciliate the strained relations between the two countries.

Jaishankar said that the border needs to be completely demilitarised for normal relations with China. He added that, “the frictions and tensions that arise from China’s deployments since April 2020 cannot be reconciled with a normal relationship between the two neighbours.”

Doval called for a de-escalation at the border. Several talks in the past on the level of military commanders at the border have not resulted in any solution. Both the countries have thousands of troops and warfare equipment amassed at the borders.

The ministers also talked about the current situation in Ukraine. Both the countries called for an immediate ceasefire. Both India and China have close bilateral ties with Russia and have not yet condemned its invasion of Ukraine.

Wang arrived in India in secrecy without any notification from either of the governments to the public. Wang left India for Nepal late Friday following an initiative by China to strengthen relations with South Asian countries.

Previously, India criticised the comments made by Wang Yi about the disputed territory of Kashmir at the Organisation of Islamic Cooperation Summit held in Pakistan.

Greg Abbott was sworn in on Tuesday as the first new governor for the state of Texas in fourteen years. Abbott replaces Rick Perry, who was elected in three consecutive elections as the state’s Governor. Although Perry was not, Abbott is an attorney and recently served as the state’s Attorney General.

During his inauguration speech, Abbott spoke about the issue of border security in the state by saying, “We must do more for the millions of Texans who are tired of seeing our state sovereignty and the rule of law ignored by a federal government that refuses to secure our border”. Abbott in his speech did not address recent drops in state revenue tied to declining oil and gas prices.

Although the state has over a US$1 trillion per-year economy, some economists suggest tough times may be on the horizon as energy prices slump. Fundraising of over US$4.5 million supported the inaugural celebration in the state capital of Austin, including a parade. Abbott is the first Governor in the US to routinely use a wheelchair since George Wallace, former governor of Alabama.

Wednesday, March 29, 2006The Australian House of Representatives today acknowledged the impact of the recent devastating Cyclone Larry and the efforts of the support given to the residents and communities of north Queensland in order to restore normal life.

Phillip Ruddock (Liberal, Berowra) moved a motion expressing this after Question Time today, which included a description of the devastation wrought on the area, the response by the Australian Government and the Australian Defence Force, and thanked the efforts of people for their “willingness to roll up their sleeves and get on with the job of cleaning up and rebuilding their towns and centres.”

The Leader of the Opposition, Kim Beazley (Labor, Brand) supported the motion, and congratulated the move to put General Peter Cosgrove in charge of operations, stating that soldiers “know how to work through logistics issues…how to work around officialdom or blockages”, praised both local federal and state members of Parliament, and especially the Labor Queensland state premier, Peter Beattie.

Bob Katter (Independent, Kennedy) was more critical in his speech. Katter thanked Beattie for his immediate response, but also described his confrontation with him and said how first responses were “simply not working”, but also praised Beattie’s decision on Cosgrove. Katter also described how the incident was “the worst natural disaster inAustralian history” and how the banana industry in north Queensland was decimated. Katter went on to describe the financial problems of the people in the region, the “huge gap” between the cost of rebuilding and insurance payouts, also asking “Are we going to pay people virtually nothing to sit on their backsides to do nothing or are we going to pay them a decent wage and have them rebuilding our communities for us?”

The debate is set to continue in the Main Committee, as an opportunity for many more members of the House of Representatives to speak to the motion, without taking up further time in the Chamber.
