RAF intercepts Russian bombers over Stornoway

Mike Wade


Two Russian Blackjack bombers, capable of carrying nuclear weapons, have been intercepted by RAF fighters over Stornoway in the Outer Hebrides, and escorted out of British airspace.
The action was described as “not unusual” by Wing Commander Mark Gorringe, of 111 Squadron, scrambled to intercept the bombers. He said that RAF crews had been involved in similar incidents on more than 20 occasions since the start of 2009, equivalent to once every three weeks.
The Ministry of Defence confirmed yesterday that two RAF Tornado F3 fighter jets from RAF Leuchars, in Fife, had been alerted in the early hours of March 10.
The aircraft shadowed the supersonic Tu160 bombers as they flew in the direction of the Clyde estuary, before the Russians turned north towards the Antrim coast. The Russian aircrfat left British airspace and after four hours, the Tornado crews were stood down.
The MoD took the unprecedented step of issuing photographs of the two Russian aircraft.
Wing Commander Gorringe accepted that the public would be surprised by the frequency of such incidents. “Our pilots, navigators and indeed all the support personnel at RAF Leuchars work very hard to deliver the UK Quick Reaction Alert Force 24 hours a day, to defend the UK from unidentified aircraft entering our airspace, or aircraft in distress,” he said.
Experts say that the Russian missions have a mixture of motives. “There is probably a little bit of submarine-watching around the Clyde, there are naval exercises scheduled about now off the Scottish coast and there is probably a bit of muscle-flexing, saying “Hey, we are still here’,” said one defence source.
“These guys are not in contact with air traffic control in the UK. Any aircraft has to be identified, because one day there could be a risk”.
During the Cold War, Britain’s northern air defences were frequently tested by Soviet aircraft.

DNA Reveals New Hominid Ancestor



A new member of the human evolutionary family has been proposed for the first time based on an ancient genetic sequence, not fossil bones. Even more surprising, this novel and still mysterious hominid, if confirmed, would have lived near Stone Age Neandertals and Homo sapiens.
“It was a shock to find DNA from a new type of ancestor that has not been on our radar screens,” says geneticist Svante Pääbo of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. These enigmatic hominids left Africa in a previously unsuspected migration around 1 million years ago, a team led by Pääbo and Max Planck graduate student Johannes Krause reports in a paper published online March 24 in Nature.
The researchers base their claim on DNA from a finger bone belonging to a hominid that lived in the Altai Mountains of central Asia between about 48,000 and 30,000 years ago.
Anthropologists have generally assumed that hominids left Africa in a few discrete waves, starting with Homo erectus about 1.9 million years ago. Neandertal ancestors left between 500,000 and 300,000 years ago, followed by humans around 50,000 years ago.
But the new genetic sequence supports a scenario in which many African hominid lineages trekked to Asia and Europe in the wake of H. erectus, Pääbo suggests.
This curious sequence was extracted from a piece of finger bone unearthed in 2008 at Denisova Cave in southern Siberia’s Altai Mountains. Previous excavations of stone and bone artifacts in the cave indicated that modern humans and Neandertals lived there periodically beginning at least 125,000 years ago. Few fossils have turned up at the site.
While retrieving DNA from presumed Neandertal fossils in November 2009, Krause noticed an unusual mitochondrial sequence. Mitochondrial DNA is located outside the cell nucleus and inherited from the mother.
Krause conducted tests to confirm that the newly recovered mitochondrial DNA came from an ancient hominid rather than from bacteria or researchers who had handled the fossil. Using advanced techniques for fishing DNA fragments out of fossils, the team then assembled a complete mitochondrial genome for the Denisova individual. The same approach has yielded ancient DNA sequences for Neandertals (SN: 3/14/09, p. 5) and a Greenland man who lived 4,000 years ago (SN: 3/13/10, p. 5).
The researchers compared Denisova mitochondrial DNA to complete mitochondrial sequences from 54 people who are living today as well as a human who lived in Siberia about 30,000 years ago, six Neandertals from more than 40,000 years ago, a modern pygmy chimpanzee and a modern common chimp.
Mitochondrial DNA from the Denisova fossil differs from that of humans at almost twice as many chemical positions as Neandertal mitochondrial DNA does, Krause says.
“That number of differences is good evidence for a new hominid because simple variation can’t account for it,” remarks geneticist Morten Rasmussen of the University of Copenhagen.
Assuming that mitochondrial DNA ancestors of humans and chimps diverged 6 million years ago, the researchers calculate that a mitochondrial ancestor common to the Denisova hominid, Neandertals and modern humans lived between 779,300 and 1,313,500 years ago.
A common mitochondrial DNA ancestor of modern humans and Neandertals lived more recently, an estimated 321,200 to 618,000 years ago.
Krause and Pääbo are now directing an effort to extract nuclear DNA from the Denisova fossil. Comparisons of Denisova, Neandertal and modern human nuclear DNA are needed to confirm that the finger bone comes from a new hominid species and to check for signs of interbreeding with Neandertals or humans.
For now, the researchers refer to the Denisova hominid as “X woman,” although its sex remains undetermined until nuclear DNA can be examined.
X woman’s finger bone came from a soil layer that has yielded bracelets and other artifacts usually attributed to humans, Krause notes.
“What we can say for now is that there were at least three different forms of hominids living in the Altai Mountains around 40,000 years ago,” Pääbo says. At that same time, Homo floresiensis, better known as hobbits, occupied the Indonesian island of Flores (SN: 5/10/08, p. 7). Hobbit DNA has yet to be recovered.
In a comment published with the new report, geneticist Terence Brown of the University of Manchester says that further ancient DNA studies will “possibly increase the crowd of ancestors that early modern humans met when they travelled into Eurasia”.
Anthropologist Ian Tattersall of the American Museum of Natural History in New York City agrees. Hominid evolution over the past 6 million to 7 million years includes at least two dozen species, in Tattersall’s view. It was “practically routine” for two or more species to live in the same general area at the same time, he says.
Tattersall regards the new mitochondrial DNA sequence as so distinctive that, unless disproved by further evidence, it must represent a new type of hominid.
In contrast, anthropologist Erik Trinkaus of Washington University in St. Louis views the new genetic data skeptically. “I don’t know what to make of this, at least not until there is more substantial fossil material than a partial finger bone,” he says. “It may be going too far to propose a new hominid”.
Trinkaus, who sees fewer species in the hominid family than Tattersall, cautions that biologists have difficulty identifying different species even among living primates. For example, groups of baboons that usually live apart as apparently separate species sometimes aggregate and interbreed, muddying their classification.
Pääbo acknowledges the complexity of finding new hominids in mitochondrial DNA, which in animals such as mice can pass from one species to another via interbreeding. “But there are massive genetic differences between X woman and both Neandertals and modern humans,” he says.

Ukrainian women berate 'Neanderthal' PM for sexist remarks

Mykola Azarov enrages feminist groups by suggesting women are unsuitable for high political office

Luke Harding in Moscow

Ukraine's new pro-Russia prime minister, Mykola Azarov, has enraged feminist groups by suggesting that women are unsuitable for high political office and incapable of carrying out reforms.


Women's groups in Ukraine have angrily reported Azarov – who presides over an all-male cabinet – to the country's ombudsman following his remarks last week. They accuse him of gender discrimination and holding Neanderthal views.
Speaking on Friday, Azarov said Ukraine's economic problems were too difficult for any woman to handle.
"Some say our government is too large; others that there are no women," he said. "There's no one to look at during cabinet sessions: they're all boring faces. With all respect to women, conducting reforms is not women's business".
Ukraine's new woman-free government was capable of working 16 hours a day with "no breaks and weekends", Azarov boasted.
The prime minister's gaffe echoes comments made recently by the man who appointed him – Ukraine's new president, Viktor Yanukovych. During February's election campaign, Yanukovych declared that his female opponent, Yulia Tymoshenko, should "go to the kitchen".
Today, Azarov's political enemies denounced him as an unreconstructed dinosaur. They said his derisory remark, snubbing half of the country's 46 million population, underlined just how out of touch he is with ordinary Ukrainians.

Supreme Court grants Texas inmate last-minute stay of execution

The US Supreme Court has suspended the execution of convicted murderer Hank Skinner after a plea from France and his defense lawyers to allow further DNA tests

By News Wires


AFP - The US Supreme Court Wednesday stayed the execution of a convicted murderer less than an hour before he was due to die after a plea from France and his defense lawyers to allow further DNA tests.

Henry "Hank" Skinner has urged new DNA tests to be carried out which he says will prove he did not commit the New Year's Eve 1993 triple murder he was sentenced to death for.

Skinner, 47, who is now married to a French anti-death penalty campaigner, was convicted in Texas at a 1995 jury trial for the killings of his girlfriend and her two sons.

Earlier in day the French ambassador in Washington contacted Texas authorities urging a stay of execution.

Both French President Nicolas Sarkozy and Foreign Minister Bernard Kouchner have expressed their support to Skinner's French wife, Sandrine Ageorges-Skinner.

Super Size Me: how the Last Supper became a banquet over 1,000 years

Art imitates life as scientists discover that size of portions in paintings of Jesus's final meal grew over time
By Steve Connor, Science Editor
It is the most famous meal in history and now scientists have found that the artistic renditions of the Last Supper over the past thousand years show that the size of the plates and the amount of food being eaten by Jesus Christ and his disciples have grown significantly over the centuries.
A study of dozens of paintings of the Last Supper from AD1,000 to the more recent past has found that the depiction of Christ's final meeting with the 12 apostles suffered a type of "food inflation" normally associated with the supersized portions being served in modern-day, fast-food outlets.
Food items depicted in medieval paintings created at the turn of the first millennium are significantly smaller compared to the average size of the disciples' heads than the portions and plates drawn several centuries later, noticeably from the Renaissance onwards, the scientists said.
The findings indicate that the phenomenon of serving bigger portions on bigger plates, which has helped to push people into overeating food that they might not have otherwise eaten, has occurred gradually over the millennium, according to Professor Brian Wansink of Cornell University in New York.
"We took the 52 most famous paintings of the Last Supper and analysed the size of the entrées, bread and plates, relative to the average size of the average head in the painting," Professor Wansink said.
The study found that the size of the food portions and plates depicted in the paintings expanded significantly. The size of the main dish grew by 69 per cent, the size of the plates grew by 66 per cent and the size of the bread depicted in the paintings grew by 23 per cent over the course of the 1,000-year period, Professor Wansink explained.
"The last 1,000 years have witnessed dramatic increases in the production, availability, safety, abundance and affordability of food. We think that these changes have been reflected in paintings of history's most famous dinner," he said.
Each of the 52 paintings, taken from the book Last Supper published by the Phaidon Press in 2000, was scanned into a computer and the food items and figures analysed by computer-aided design software that could rotate objects and measure their dimensions irrespective of their original orientation in the work of art.
Professor Wansink co-authored the study published in the International Journal of Obesity with his brother Craig, professor of religious studies at Virginia Wesleyan College in Norfolk, Virginia. They wanted to test the idea that food portions have increased as food has become abundant over time.
"If art imitates life and if food resources have become generally more available over the past millennium, we might expect the size of food, the portions and the plate sizes that are depicted in these paintings, to increase over time," Professor Wansink said.
Although the Last Supper is a central part of Christian theology, and is mentioned in the gospels of Matthew, Mark and Luke, nothing is known about how much was served or what exactly was eaten, except that it included bread and wine. In the paintings, about 18 per cent of the tables served fish or eel, 14 per cent showed lamb being served and 7 per cent painted portions of pork.
"Our starting point was with the artistic representations and the portrayal of food portions and sizes. The empirical reality at an average dinner table may have been different. What stands out in the paintings is the perception that portions were greater," said Professor Craig Wansink.
"Because there were not strong theological reasons that accounted for the size of the changes in plates, main dishes, and bread in these paintings, we were just intrigued by the gradual increase. Even if people themselves weren't necessarily eating more, this emphasis on abundance is striking," he said.
"The growth seemed consistent – a generally upward slope – but increases in the 16th and 17th centuries stand out," he added.

Immigrant students suffering says OECD

Non-ethnic Danish students don’t complete as much higher education as their Danish counterparts

Students of non-Danish ethnic backgrounds and immigrants are lagging behind their ethnic Danish counterparts in education, according to a new OECD report.

The Migrant Education report is due to be published later today and investigates the education of immigrants in six European countries, including Denmark.

According to the report, immigrant students score notably poorer in tests than their fellow students.

The study also shows that while 64 percent of immigrants complete a higher education programme, 74 percent of ethnic Danish students do the same.

Immigrant students choose a business line of further education more so than a general study programme, but they suffer from a higher drop out rate, according to the report.

Education minister Tine Nedergaard accepted the OECD recommendations to improve efforts and facilities to bridge the gap and said several initiatives were already underway.

‘These initiatives will naturally take time to work and I’m convinced we will see their effect in the coming years,’ she said.

But according to Professor Niels Egelund from the Danish School of Education, if something isn’t done soon, there’s a risk of creating a new lower class of young people in society with a low competence level.

‘It can cause enormous frustration and this frustration could lead to more crime,’ Egelund told Berlingske Tidende newspaper.

Australia starting to Close the Gap: Calma


One of the leaders of the Close the Gap campaign says progress on reducing Indigenous disadvantage has been made in the past few years.
More than 30,000 people are expected to take part in the fourth annual national Close the Gap day today, focusing on measures to improve the health of Indigenous people.
Campaign co-chairman Tom Calma acknowledges there have been funding boosts for Indigenous health services in recent years, but says more is needed.
"We're all starting to face in the right direction and starting to walk in the right direction," he said.
"More and more people [are] understanding that it is unacceptable that in a developed country like Australia we have third-world health outcomes".
Mr Calma says the Federal Government should establish a comprehensive plan of action to ensure all agencies involved in health are working together to close the gap.
"The key issue is to address access, particularly at the primary health care level," he said.
"That means building up the capacity and the reach of the Aboriginal community-controlled health services.
"We need to make sure that the mainstream medical facilities are going to be accessible and used by Aboriginal and Torres Strait Islander peoples".

Russian maths genius Perelman urged to take $1m prize


Russian maths genius Grigory Perelman, who declined a prestigious international award four years ago, is under new pressure to accept a prize.
A US institute wants to give him $1m (£700,000) for solving one of the world's most complex mathematical problems, the Poincare Conjecture.
But it is unclear whether Dr Perelman, a virtual recluse, will pick it up.
A children's charity in St Petersburg, where he lives, has urged him to take the money and give it to charity.
Dr Perelman, 43, has cut himself off from the outside world for the past four years, living with his elderly mother in a tiny flat said by neighbours to be infested with cockroaches.
In an open letter on its website, the Warm Home charity called on Dr Perelman to give the cash equivalent of the US Clay Mathematics Institute's $1m Millennium Prize to Russian charities.
It suggested that the mathematician had already made an ethical point by turning down the Fields Medal, the world's highest prize in mathematics, in 2006.
Appeal for privacy
The mathematician is reported to have said "I have all I want" when contacted by a reporter this week about the Clay Millennium Prize.
According to the UK's Daily Mail newspaper, he was speaking through the closed door of his flat.
Dr Perelman was the first person to turn down the Fields Medal, which would have been presented to him at the International Congress of Mathematicians in Madrid.
"I'm not interested in money or fame," he is quoted to have said at the time.
"I don't want to be on display like an animal in a zoo. I'm not a hero of mathematics. I'm not even that successful; that is why I don't want to have everybody looking at me".
One of Russia's most senior politicians, Federation Council Chairman Sergei Mironov, has appealed for Dr Perelman to be left in peace to make up his own mind.
He suggested that it was "not very decent to look into other people's pockets and count other people's money", Russia's Interfax news agency reports.

German Shipping Faces Wave of Financing Problems


By Beat Balzli and Wolfgang Reuter

As recently as 2008, container ships were transporting record amounts of products across the world's oceans. Now, many German shipping companies are struggling to pay for the vessels they ordered during the boom. Their banks could be in trouble, too.

Major shipowner Bernd Kortüm and his wife were enjoying fresh snow in the Austrian ski resort of Lech last week. "The crisis is almost over," Kortüm, one of Hamburg's richest residents, said calmly, noting that things are beginning to look up for his industry. But the owner of a fleet of 102 container ships was exaggerating mightily.

Less than a year ago, Kortüm and his company, Norddeutsche Vermögen, were on the brink of collapse. Hamburg-based commercial lender HSH Nordbank had previously set aside risk reserves of close to €250 million ($338 million) to cover a credit line in the billions. "Because of the inadequate economic circumstances," the auditors of KPGM wrote, there were "acute risks of default". The lender was even threatening an extraordinary termination of loan agreements.



It was only last November that Körtum was able to put together a financing agreement with HSH. And it only came about due to the shipowner's willingness to make a substantial contribution from his private fortune. He is unwilling to reveal how much he is paying, but he does admit that there are problems. "The recently concluded charter rates are not covering total costs yet," says Kortüm, adding that eight of his ships are "without revenue".

Things are hardly looking any better for the rest of the German shipping industry. Despite a slight recovery in the freight market, many shipowners and ship funds face critical questions about their financial survival.

The crisis is also eating its way into the foundations of German banks. Institutions like HSH Nordbank, Commerzbank, Nord/LB, state-owned bank KfW's subsidiary Ipex and DVD Bank are the world's biggest ship financiers, with close to €100 billion in ship loans on their books.

At Anchor Worldwide

For many of the borrowers, it has become a question of survival, and the subject of profits hardly comes up at all anymore. Depending on the type of ship, charter rates are up to 80 percent lower than before the crisis, when they were at their highest point. In fact, writes Hamburg shipbroker Harper Petersen & Co., charter rates have arrived at "a painfully low level, and most shipowners are still losing money". For lack of contracts, almost 500 ships are currently at anchor in ports worldwide.

In the boom years, intoxicated with their success, German shipowners ordered $60 billion worth of new ships. Banks were expected to provide 70 percent of the financing, while shipowners planned to drum up the rest of the money from German small investors through so-called "ship funds" set up by brokerage firms like HCI, MPC and Lloyd. But now investors are balking. The supposedly safe ship funds, which had promised high returns subject to minimal tax rates, are suddenly requiring additional investments to cover their losses.

With the first funds already capitulating, shipowners can no longer depend on selling shares in new ship funds to finance their current orders.

Although brokerage firms and shipowners guarantee the equity shortfall for which the banks are now providing interim financing, they are unable to come up with the cash. "In theory, many are bankrupt," says Hamburg industry expert Jürgen Dobert. "But the banks are deferring debt service and are not enforcing their claims because they know that an entire house of cards could collapse if they did".

In the worst case, shipowners would have to sell ships from their fleets. "This would lead to new market distortions that would affect shipowners, shipyards and banks," one banker warns. Fire sales would depress already low ship prices even further, thereby reducing the value of the banks' collateral.

Not Even Discussed

Where, then, is the money supposed to come from? Not from the government, at any rate. Last fall, two major Hamburg shipowners, Claus-Peter Offen and Peter Döhle, tried in vain to obtain funds from the €115 billion German Economic Fund, which was passed in 2009 to help private companies weather the economic storm. The government's €1.2-billion loan guarantee for the Hapag Lloyd shipping line remains an exception.

The German government's negative stance toward the shipping industry hasn't changed. At a crisis meeting in the Economics Ministry last Thursday evening, the industry's request for a €10 billion loan guarantee was not even brought up.
Instead, the roughly 50 industry representatives agreed to a 13-point plan with top government officials and Hans-Joachim Otto, the federal government's maritime coordinator. So far, the plan primarily calls for a number of studies. The goal is to examine whether the federal government can move up public shipbuilding orders, partly in connection with development aid, such as those for ferries in Africa. In addition, the industry wants to determine whether the government-owned KfW bank can relax the requirements for obtaining funding from the German Economic Fund.

This will hardly be enough. Some 1,000 ships ordered by German shipowners have not yet been delivered. They include about 300 giant container ships, with an estimated value of about €30 billion.

The maritime business is having a significant impact on bank balance sheets. The division of government-supported Commerzbank that is partly responsible for ship financing lost close to €850 million in 2009.

Succumbed to the Temptations

Ailing lender HSH Nordbank, the world's largest shipping industry financier, doubled its reserves to €1 billion for the 2009 fiscal year. Ship loans worth about €35 billion are languishing on the books of the Hamburg-based lender. An auditor's report on HSH Nordbank reveals how threatening many a ship loan was for the bank -- and, in some cases, still is.

The auditors were particularly interested in the Kortüm case. With a credit line of €2 billion at the end of 2008, the shipowner is one of the bank's biggest customers. He had also succumbed to the temptations of the boom years. His floating cash machines were such tremendous moneymakers that he embarked on a veritable ordering frenzy shortly before the crisis erupted.

Kortüm couldn't have picked a worse time to expand. He and his wife were on a sailboat headed for Australia on Sept. 15, 2008, the day US investment bank Lehman Brothers went under. The volume of freight orders for ships declined sharply, and the bankers at HSH became alarmed.

By now, all of Kortüm's new ships have charter agreements. But his company, Norddeutsche Vermögen, will be forced to acquire two new ships without the help of outside investors due to lack of interest in shipping funds. Indeed, leading ship fund businesses have their backs to the wall. In February, HCI was able to negotiate a moratorium with its creditor banks, deferring payments until Sept. 2013, in a move that saved them from bankruptcy. Other brokerage firms are still in talks.

Cases like Kortüm's are the rule rather than the exception at HSH Nordbank. Another example is the Danaos Group, most of which is owned by Greek shipowner John Coustas. Until recently, the 53-year-old was counted among the world's richest men. But according to an audit report by KPMG, the group owed Hamburg banks more than half a billion euros by the end of 2008. In their report, the auditors wrote that the Coustas fleet was expected to include "30 new ships with delivery dates through 2011".

Acute Risks

In 2008, HSH lent more than €400 million to Dryships Inc., a ship holding company, which even includes two mobile drilling barges in its fleet. It is now unclear whether the loans will be repaid in full. The financial markets, at any rate, have largely lost confidence in the company, whose stock price has declined sharply, from more than $80 to about $6 a share.

HSH is unwilling to provide any information about individual borrowers. But bank executives are making a deliberate effort to appear unperturbed. No one at HSH is willing to admit that there are acute risks, not to mention a threat to the bank's very existence. CEO Dirk Jens Nonnenmacher is already promising profits for 2011.

"The ships have financing periods of 13 years, but lifespans of 25 years," says HSH division manager Harald Kuznik, who also attended last week's crisis meeting in Berlin. In other words, he adds, shipowners can defer debt repayment during the crisis "without losing money in the end." In addition, he says, the major shipping lines, such as Hapag Lloyd, are "operationally out of the woods".

Industry expert Dobert, however, sees all of this as "nothing but cheap propaganda" since the future development of the economy is still up in the air. "If consumer spending doesn't pick up and remain strong," he warns, "the shipping lines won't have much to do soon".
