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 Supreme Court of Angola yesterday summoned President José Eduardo dos Santos to explain his decision to appoint his daughter head of the national state-owned oil firm, Sonangol. The pair face claims of nepotism and breach of probity legislation.

Isabel dos Santos, Africa’s richest woman according to Forbes, is also summoned. She took control of Sonangol in June after her father fired the entire board. Angola is now the continent’s largest oil producer, surpassing Nigeria after militancy affected production there. The company nonetheless is struggling to cope with reduced prices for oil.

The court’s move comes as it accepts a petition by a group of lawyers against the dos Santoses. “It is the first time that the court will examine a decision of the president,” said one of them, David Mendes. “The law stipulates that public officials cannot nominate or allow the nomination of family members,” he added yesterday.

According to Mendes the dos Santoses have eight days to answer the court. One member of ruling MPLA anonymously told reporters “The constitution of Angola is clear: the president does not have to personally explain actions taken during his term in court or in parliament”. He said a representative would appear instead.

José Eduardo dos Santos has ruled for over 30 years, but has expressed an intention to resign in 2018 following elections next year. Three years ago his son Jose Filomeno dos Santos was made head of the national Sovereign Wealth Fund. Isabel dos Santos owns shares in both Angolan and Portuguese businesses, particularly financial and telecoms firms.

Member states of the eurozone have offered to give Greece thirty billion euro in emergency loans for the debt-stricken country, should the latter want it.

The loans’ price will be determined using formulas by the International Monetary Fund (IMF), and will be set at around five percent.

The Luxembourgish prime minister, Jean-Claude Juncker, speaking on behalf of eurozone finance ministers, commented that “[t]he total amount put up by the eurozone member states for the first year will reach 30bn euros.” He added that “[t]his is certainly no subsidy” to Greece.

The prime minister also noted that financing would be “completed and co-financed” by the IMF. European Union monetary affairs chief Olli Rehn remarked that the IMF would make a “substantial contribution” to the loan package as well, perhaps around ten billion euros.

The Greek economy has spent more than it has earned for several years now, and currently faces a budget deficit equal to 12.9% of its economic output, or a total debt of 300 billion euros. The country intends to try and reduce the deficit to 8.7% this year.

Global chemical manufacturer LyondellBasell — the third-largest private chemical company in the world — has collapsed. The firm filed for Chapter 11 bankruptcy protection in the United States, as well as the Dutch equivalent. They had failed to meet a January 4 deadline on postponed debt payments, and talks with creditors failed.

Headquartered in The Netherlands, LyondellBasell is owned by private equity tycoon Len Blavatnik, who had already refused the company a loan to help deal with debt resulting from a $12.7 billion merger between Basell International Holdings and Lyondell Chemical to create LyondellBasell Industries.

The company had already appointed Kevin McShea from Alix Partners to restructure the firm. McShea was assigned speculatively prior to the bankruptcy filing. Access Industries, Blavatnik’s company, refused to extend credit as part of a loan deal brokered in March, a decision Lyondell Chemicals Company, a subsidiary of LyondellBasell, stated they were unhappy with.

LyondellBasell had postponed $280 million worth of interest payments, which Standard & Poor said placed it in “selective default” with a “rapidly weakening liquidity position”. S&P also said that LyondellBasell have debts of $26 billion in a report on the company prior to the firm’s collapse.

LyondellBasell responded with a press release, issuing the following statement: “Standard & Poor’s definition of ‘selected default’ related to our corporate credit rating should not be misinterpreted to suggest that LyondellBasell is currently in default of its bank agreements. As they stated in their press release, ‘This is a default in our opinion according to our definitions and criteria.’ LyondellBasell is not currently in default according to its agreements with its lenders.”

The company met with high oil prices shortly after the expensive merger. This was followed by a general tail-off in demand caused by the ongoing financial crisis. Investors were continuing to bet before the collapse that the firm would restructure under bankruptcy protection, leaving lenders with big losses, potentially over 90% of their investments. The cost of credit protection for LyondellBasell bonds had soared. The creditors include Merrill Lynch, Goldman Sachs, Citigroup, ABN Amro and UBS.

On Thursday, an interim allowance was made by a judge for LyondellBasell to seek up to $2.167 billion of loans. There is also an emergency loan paid out of $100 million. As well as LyondellBasell, 79 affiliates have become insolvent. Citigroup has said the collapse will set them back $1.4 billion in unpaid debts.

Local municipal and provincial volunteers in Manitoba, Canada are exhausted in their efforts to divert the rising waters of the Red River of the North.

It has been hard work with little sleep for the residents who live on the shores of the Red River to shore up their defences with sandbags, build dikes, clear frozen culverts and break ice jams

Volunteers to spell relief for local volunteers and food are desperately needed.

“It’s a week now we’ve been doing this … you’re talking four, five, six public works guys. In my one community we’ve got 25 volunteer firefighters and those guys have been going 24/7, so of course it’s wearing them down.” said Paul Guyader, Manitoba’s emergency measures coordinator.

“We’re dealing with one of the biggest floods the province has ever seen,” said Steve Strang, mayor of St. Clements, Manitoba “We’ve put out hundreds of thousands of bags already. The municipalities are working very well, we’re working with the provincial government, we’ve brought in every possible resource we could to address this issue. The volunteerism within the community has been phenomenal.”

The Portage Diversion has taken some spring waters from the Assiniboine River and diverted the flow to Lake Manitoba.

Roseau River Anishinabe First Nation has been totally evacuated, as well as many homes near the Canada – United States border.

The cold weather is freezing the ice jams into place. Guyader has had 2 Amphibex Excavators operating on the river breaking up ice.

The Red River is right now 16.7 feet (5 metres) above spring ice conditions. The Red River Floodway gates cannot be opened with the current ice jams.

“If we operate now, we can get ice jamming going into the floodway, jamming up against the St. Mary’s bridge, as such, the floodway capacity would be reduced and would cause higher water levels in the city of Winnipeg.” said Steve Topping, Manitoba Water Stewardship spokesman

The floodway was constructed in 1968 following the 1950 flood to divert the overflow spring flooding waters of the Red River. The floodway has been widened the since the 1997 “flood of the century” and the expansion is expected to be completed this spring. As well Manitoba built permanent dikes around communities within the flood plain since the last two major floods..

The Red River waters will crest between the beginning of April to mid April, at which time also the weather should be warming up. Communities are bracing for higher water levels, more ice jams as well as melting snow in the warmer spring temperatures.

Officials in Mumbai, India, demolished over 6,000 shanties today in a push to eradicate the capital city’s slums. In total, 39,000 shanties have been flattened, displacing over 200,000 people, in the city’s biggest-ever demolition drive, which began in early December.

When complete, over 2 million people are expected to be displaced. After wiping out the least desirable shanties, next in line for demolition are the illegal ‘well-off’ shanties and neighborhoods, according to the legal and bureaucratic motions that have been executed toward cleaning up Mumbai’s appearance by lowering the dominance of shanties, which make up 62 percent of Mumbai’s housing.

“As far as eye can see, there are mounds of wood, tin and tarpaulin, the remains of 6,200 illegal homes, flattened by a heavy excavator running on tank-like tracks and giant motorised claws,” the Indian Express reported about today’s destruction. [1]

Chief Minister Vilasrao Deshmukh said that citizens would see a change within six months. “Every chief minister likes to be remembered, and I’m no exception,” said Deshmukh, who despite having an empty exchequer, also announced that Rs 31,000 crore will be spent on new roads, sea links and rail lines.
