Russian chess grandmaster, Vladimir Kramnik lost the final match of his man versus machine match against the Deep Fritz chess program. The six game match in Bonn, Germany had a final result of 4-2 for the German-developed chess program which runs on readily available computer hardware.

The first match which concluded on November 25 was a draw, Kramnik lost the second game to the computer with some indications that he overlooked a mate in one win. Third through fifth matches were all draws.

Kramnik, whilst the current world chess champion, is actually ranked third in the world. A contributory factor in this is his health problems. The world champion suffers from a rare form of arthritis which makes sitting playing in tournaments extremely painful for him.

Mauritanian refugees stuck in Senegal for nearly two decades after fleeing ethnic clashes in their home country have begun returning to Mauritania under a U.N.-sponsored program. But many do not want to return.

There were goodbye ceremonies and welcoming ceremonies attended by officials on both sides of the Senegal River as more than 100 former refugees were ferried on motorized pirogues.

A spokesman for the United Nations refugee agency, Alphonse Munyaneza, explained international funding will help pay for resettlement.

“Each refugee returning back to Mauritania will receive a piece of land equivalent to 140 square meters for establishing a house. UNHCR and the government of Mauritania will provide construction material so that they can build a house,” explained Munyaneza. “We will provide three months of food ration. We will provide a tent also.”

Mauritanian refugee children broke out in song and laughter when officials arrived at their camps close to the border to get the process going.

There are more than 20,000 Mauritanian refugees in Senegal. Officials say the return program will extend over 18 months.

One of those happy to go is Haddy Sy. She says she left Mauritania after she was beaten up. This took place during a wave of ethnic violence that began in Arab Moor-dominated Mauritania in 1989 and escalated into border clashes, forcing tens of thousands of black, mostly ethnic Fula, Mauritanians into exile.

In the late 1990s, more than 30,000 refugees returned by their own means and some U.N. assistance.

Sy says she is leaving behind many good things in Senegal, including a peaceful setting, but that she is still happy to return to her home country.

Since taking office last year, the government of the elected, post-coup President Sidi Ould Cheikh Abdallahi has been making efforts to bring home the refugees, including several thousand more in Mali.

But many in Senegal do not want to return home, like Yaraah Sow, who lives in the Dagana refugee camp about 400 kilometers northwest of Dakar.

He says he is still very bitter about what happened nearly 20 years ago. He said his father, who was a civil servant, was attacked by a mob and died of internal bleeding at the gates of a hospital after doctors refused to treat him.

Sow accuses the military of seizing all his family’s property. He says that two of his younger brothers died on the trip to Senegal. He says his children are now going to school and that they are better off in Senegal.

One of the refugee leaders, Mohamed Ali Sow, who left when he was 10, says he is studying at a university in Senegal to become a lawyer to defend the rights of chased out Mauritanians.

He says the return program has been rushed, because he says people who had their property seized, houses burned, and jobs taken away, should have guarantees these will be restored. He says until then, he does not think it is wise to go back.

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 court in England, UK has jailed a policeman for ten months after he was convicted of defrauding his car insurance company.

Police Constable Simon Hood, 43, arranged for a friend who dealt in scrap metal to dispose of his Audi TT, then claimed it had been stolen.

Hood had been disappointed with the car’s value when he tried to sell it two years after its purchase in 2008. He arranged for friend Peter Marsh, 41, to drive the vehicle to his scrapyard in Great Yarmouth, Norfolk. Marsh then dismantled the vehicle with the intent of disposing of it, but parts were later found wrapped in bubblewrap at Ace Tyre and Exhaust Centre.

Marsh picked up the TT from outside nearby Gorleston police station. Records show mobile phone conversations between the conspirators that day in March, both before and after the vehicle was reported stolen. The pair denied wrongdoing but were convicted of conspiring to commit insurance fraud after trial.

The fraud was uncovered after Hood told former girlfriend Suzanne Coates of the scheme. It was alleged before Norwich Crown Court that he had confessed to her in an effort to resume their relationship. Coates said that after the pseudotheft, Hood told her “he didn’t want to look for it. He said it would be like looking for a needle in a haystack, which I thought was a bit strange.”

Shortly afterwards Hood suggested they should become a couple once more, she said; she challenged his version of events regarding the car: “He said he did it but I couldn’t tell anyone. He said he did it with Peter. Peter had a key and took the car away and it was going to be taken to bits and got rid of so it was never found.”

Hood was defended by Michael Clare and Marsh by Richard Potts. Both lawyers told the court that their clients had already suffered as a result of the action in mitigation before sentencing. Clare said Hood had resigned from the police after fifteen years of otherwise good service and risked losing his pension. “It is not a case where his position as a police officer was used in order to facilitate the fraud,” he pointed out. “His career is in ruins.” Hood is now pursuing a career in plumbing.

Potts defended Marsh by saying that he, too, had already suffered from his actions. His own insurers are refusing to renew their contract with him when it expires and his bank withdrew its overdraft facility. His business employs 21 people and Potts cited Marsh’s sponsorship of Great Yarmouth In Bloom as amongst evidence he supported his local community.

Judge Alasdair Darroch told Marsh that he did accept the man was attempting to help his friend. He sentenced Marsh to six months imprisonment, suspended for two years and ordered to carry out 250 hours of community service. He was more critical of Hood:

“As a police officer you know the highest possible standards are demanded by the public. You have let down the force. You knew throughout your career that policemen that get involved in serious dishonesty get sent to prison.”

Monday saw the latest edition of the vetted version of Wikipedia, which is aimed at educational use, go quietly online. The extensively revised version covers over five thousand topics, targeting the eight to seventeen years age group. Partnerships with the Shuttleworth Foundation and the Hole in the Wall project will see it distributed in South Africa and India as well as copies being available globally via the offices of SOS Children UK’s umbrella organisation, SOS Kinderdorf worldwide.

First launched in 2006 as a 4,000 article edition, the extract of Wikipedia has employed hi-tech distribution methods, as well as offering a website version which has steadily climbed up in ranking to above other reviewed Wikipedia rivals and copies; the 2007 version was available on the BitTorrent peer to peer network to keep distribution costs down and was equivalent to a fifteen-volume printed encyclopedia. Monday’s release is compared to a twenty-volume print edition.

Key to the process for selecting articles is the English National Curriculum and similar educational standards around the world. The initial vision was to bring this wealth of knowledge to schools where access to the Internet was poor or unavailable, but copies of Wikipedia for Schools can be found on many first world school intranets and web servers. Among the compelling reasons to adopt the project are the vetting and additional study materials which overcome the oft-publicised concerns many educators have with the million article plus Wikipedia that anyone can edit.

In today’s press release announcing the launch, Wikimedia Foundation Executive Director Sue Gardner expressed delight at seeing the project bring out a new version, “Our goal is to make Wikipedia accessible to as many people as possible around the world, and SOS Children is a great partner that helps us make that happen. Wikipedia is released under a free content license so that individuals and institutions can easily adapt, reuse and customize its content: we encourage others, like SOS Children, to do exactly that.”

Running 192 schools in the developing world, SOS Children sees Wikipedia for Schools as a key piece in fulfilling the educational aspect of their mission. SOS Children’s Chairwoman, Mary Cockcroft gave us an introduction and, a Wikipedia administrator himself, the charity’s CEO Andrew Cates spoke to Wikinews at length about the project.

You are part of SOS-Kinderdorf International, can you explain a little about how this works in terms of distributing funds raised in the UK and involving UK citizens in work outside the country?

Mary Cockcroft: SOS Children[‘s Villages] is a “club” of member charities in 130 countries helping orphans and vulnerable children. The club elects SOS-Kinderdorf International as secretary. SOS is a large organisation whose members in aggregate turned over $1bn in 2007, and whose projects include owning and running 192 schools and family-based care for 70,000 children. However much of these funds are raised locally, with for example the member charities in each of India, Pakistan and South Africa raise considerably more funds in their own country than SOS UK does from the UK. Nonetheless SOS Children UK principally raises funds to finance projects in the developing world, and has only financially small projects in the UK (such as the Schools Wikipedia, which is very low cost because of extensive use of volunteers). This year we expect about 80% of our UK income will leave the UK for overseas SOS associations, and some of the remaining 20% will pay for project oversight. We do not spend money in the UK on Direct Mail or TV advertising. Our UK office is involved in overseeing projects we finance and a small number of high-skilled volunteers from the UK help overseas. However around 98% of SOS staff worldwide are local nationals, as are most volunteers.

((WN)) How much work does the UK charity actually carry out within the home country? Are there failings within the government system for orphans and other needy children that you feel obliged to remedy?

MC: We are deeply unhappy about the situation of children in out-of-home care in the UK. However our care model of 168 hour-a-week resident mothers does not fit with the UK philosophy for children without parental care. Internationally SOS always has a policy of sharing best practice and we are working to improve understanding of our way of working, which appears to us to have far better outcomes than the existing one in the UK. Ultimately though the legal responsibility for these children lies with government and we cannot remedy anything without their invitation.

((WN)) Who first came up with the idea of doing a vetted Wikipedia extract? What was the impetus? Was it more for the developing world than first world?

Andrew Cates: I honestly cannot remember who first suggested it, but it came from somewhere in the Wikipedia community rather than from the charity. The original product was very much pitched at the developing world where the Internet is only available if at all over an expensive phone line. I worked in West Africa 1993-1996 and I know well at how thirsty for knowledge people are and how ingenious they will be in overcoming technical obstacles if the need for infrastructure is removed.

((WN)) In reading past year’s announcements there’s some pride in the project being picked up and used in the first world, was this expected or a pleasant surprise?

AC: It was a pleasant surprise. I don’t think we had realised what the barriers schools faced in using the main Wikipedia were. It isn’t just pupils posting material about teachers or meeting strangers: the “Random Article” button on every page could potentially deliver an article on hardcore porn. We had already started when discussion broke on banning Wikipedia from classrooms and I am sure we benefited from it.

((WN)) Can you give an outline of the selection and vetting process? Is it primarily Wikipedians working on this, or are people from the educational establishment brought in?

AC: It was a long and painful process, even with a really good database system. Articles were taken into the proposal funnel from three main sources: direct proposals for inclusion from Wikipedians, lists which came from the Release Version team and proposals drawn up from working through National Curriculum subjects by SOS volunteers. In a few cases where we felt articles were missing we asked the community to write them (e.g. Portal:Early Modern Britain, which is a curriculum subject, was kindly written just for us): These “proposals” were then looked at by mainly SOS volunteers (some onwiki, some offline). Our offices are in the middle of Cambridge and we get high quality volunteers, who skim read each article and then compared two versions from the article history by credible WP editors a significant period apart (this picks up most graffiti vandalism which runs at about 3% of articles). Once they had identified a “best” version they marked any sections or text strings for deletion (sections which were just a list of links to other articles not included, empty sections, sex scandals etc). A substantial sample of each volunteers work was then doubled checked for quality by one of two office staff (of whom I was one). We then have a script which does some automated removals and clean ups. Once we had a selection we posted it to relevant wikiprojects and a few “experts” and got any extra steers.

((WN)) Will you be making use of BitTorrent for distribution again this year? Was it a success in 2007?

AC: BitTorrent was a bit disappointing in that it got us the only substantial criticisms we received online. A lot of people find it too much effort to use. However for the period we offered a straight http: download we had huge problems with spiders eating vast bandwidth (the file is 3.5G: a few thousand rogue spider downloads and it starts to hurt). As per last year therefore our main two channels will be free download by BitTorrent and mailing the DVDs free all over the world. At a pinch we will (as before) put straight copies up for individuals who cannot get it any other way, and we have some copies on memory sticks for on distributors.

((WN)) Is it your opinion that the UK Government should be encouraging the adoption of projects like this as mainstream educational resources?

AC: Clearly yes. We have had a very enthusiastic reaction from schools and the teaching community. We think every school should have an intranet copy. We expect the Government to catch on in a few years. That is not to say that Wikipedia is as good as resources developed by teachers for teachers such as lesson plans etc. but it is a fantastic resource.

((WN)) You’re a Wikipedia administrator, all too often a thankless task. What prompted you to get involved in the first place? What are the most notable highs and lows of your involvement with the project?

AC: Funnily the thing I have found most amazing about Wikipedia is not widely discussed, which is the effect of Wikipedia policies on new editors. I have seen countless extreme POV new editors, who come in and try to get their opinions included slowly learn not only that there are other opinions to consider but that elements of their own opinion which are not well founded. Watching someone arrive often (on pages on religions for example) full of condemnation for others, gradually become understanding and diplomatic is one of the biggest buzzes there is. The downside though is where correcting things which are wrong is too painfully slow because you need to find sources. I was a post-doc at Cambridge University in combustion and I know the article on Bunsen burners has several really significant errors concerning the flame structure and flow structure. But sadly I cannot correct it because I am still looking around for a reliable source.

((WN)) Do you believe schools should encourage students to get involved contributing to the editable version of Wikipedia? Does SOS Children encourage those who are multilingual to work on non-English versions?

AC: I think older students have a lot to learn from becoming involved in editing Wikipedia.

((WN)) To close, is there anything you’d like to add to encourage use of Wikipedia for Schools, or to persuade educators to gain a better understanding of Wikipedia?

AC: I would encourage people to feed back to the project online or via the charity. The Wikipedia community set out to help educate the world and are broadly incredibly well motivated to help. As soon as we understand what can be done to improve things people are already on the task.

((WN)) Thank you for your time.

Leaders of African Union (AU) member states met in Niamey, Niger’s capital, for an AU summit where on Sunday Presidents Muhammadu Buhari of Nigeria and Patrice Talon of Benin signed the African Continental Free Trade Area (AfCFTA) agreement.

Nigeria previously announced it planned to join the AfCFTA in the week leading up to the summit. AU trade and industry commissioner Albert Muchanga announced Benin was to join. The commissioner said, “We haven’t yet agreed on rules of origin and tariff con[c]essions, but the framework we have is enough to start trading on July 1, 2020”.

Niger’s president Mahamadou Issoufou said, “Nigeria is Africa’s biggest economy and most populous country. Without Nigeria the free trade zone would’ve been handicapped.”

The agreement seeks to remove tariffs on 90 percent of commodities and better intregrate African economies.

At the opening of the AU summit, AU chairperson President Abdel Fattah el-Sisi of Egypt said, “The success of the AfCFTA will be the real test to achieve the economic growth that will turn our people’s dream of welfare and quality of life into a reality”.

With Sunday’s signings, all but one of the member states of the 55-member AU have signed on to the agreement, with Eritrea the only state unsigned. African leaders have negotiated the deal over the last four years. While 54 nations have signed onto the AfCFTA, only 27 have ratified the agreement.

While many transactions in Africa occur using U.S. dollars or euros, the AU announced an electronic pan-African payment system.African Export–Import Bank president Okey Oramah said the use of third-party currencies “costs Africa between $5 and $7 billion,” further saying, “Beyond that, it also reduces trade because Africa has a scarcity of foreign exchange.”

There are reportedly 1.3 billion people in the free trade area, with the combined economies of the countries worth US$3.4 trillion. One of the stated goals of AfCFTA is to encourage more intra-Africa trade. Currently about 16–17 percent of African trade occurs between African countries. This is in contrast to the European Union members, where intra-European trade accounts for over 60 percent of trade.

The International Monetary Fund said in May the AfCFTA might be for African countries comparable to the European and North American trade blocs as an “economic game changer”.

Seven members states had bid to host the AfCFTA secretariat, the operational organ of the free trade agreement, with Ghana winning the bid.

A number of properties in a Hare Krishna village in Kazakhstan were demolished on November 21, by the local authorities, causing international outrage by religious freedom groups and Hindu associations alike. Since the attack fears are now rising within the community of further demolition to the remaining properties, including the main temple structure.

“The community is in shock, but they are determined to defend their homes and place of worship,” community member Govinda Swami told Forum 18 News Service. He says destruction of the temple would be “devastating”.

The authorities in Kazaksthan claim that the Hare Krishna devotees had no official right to their homes. However human rights activists Ninel Fokina and Andrei Grishin, state in reply that while 13 out of the 66 Hare Krishna homes were destroyed on court orders, “the adjacent houses of other people who do not belong to the Society for Krishna Consciousness were left untouched even though their title deeds have the same status”.

The Hare village itself, known as ‘Sri Vrindavan Dham commune’ (named after Vrindavan forest in India is based in the Keskelen district, in the town of Seleksia, close to Almaty. It was the only village of it’s type run by Hare Krishna devotees in the country.

According to human rights activist Yevgeni Zhovtis: “Unfortunately Kazakh law does not prohibit evictions during the winter period and also does not oblige the court bailiffs to give those being evicted a few days notice,” “All the same, there were crude violations of the law. The court bailiffs had the right to evict the residents of the houses but not to demolish the buildings themselves. It was also a very crude violation to throw the belongings of the Krishna devotees into the mud. The court bailiffs were obliged to put the devotees’ belongings into store.”

Local journalist Grishin claims to have had his camera confiscated by the Police and to have been threatened “If I see you here again, I will personally smash your eyes, even though I am the hakim.”

Protests are being made by Hindu groups and members of the International Society for Krishna Consciousness around the world in an attempt to halt any further demolition or other forms of alleged religious persecution. Groups within the UK have brought the issue to the attention of both Tony Blair, and the House of Commons.

One of the Indian political parties, Bharatiya Janata Party criticised the central government for keeping silence over the issue. The party is expected to follow the saffron brotherhood agenda in the second term of Rajnath Singh.

American and European scientists say the upgraded Hubble space telescope has spotted the oldest galaxies ever seen. The images were taken with the telescope’s new Wide Field Camera 3 (WFC3) in August this year.

The galaxies are about 13 billion light years from Earth, meaning they formed less than one billion years after the Big Bang — the cosmological model of the initial conditions and subsequent development of the universe.

WFC3 was installed in May this year, during a mission by the space shuttle Atlantis to repair and upgrade Hubble. Experts say the new instrument will let them peer even further back in time, to when the universe was in its infancy. The more distant a galaxy is, the more its light is “redshifted” due to expansion of the universe. Light from the furthest galaxies is shifted to infrared wavelengths invisible to the human eye, but WFC3 can detect these.

The new image was taken in August, in the same region as a 2004 visible light image known as the Hubble Ultra Deep Field. The 2004 photo previously showed the most distant galaxies, but the new infrared pictures from the WFC3 allow even more remote galaxies to be seen.

Capturing the image took four days, and the total exposure lasted 173,000 seconds. In the three months since, twelve scientific papers have been submitted on it. On Tuesday one of these confirmed the galaxies as the furthest ever seen.

They are also the oldest, with the light from them having taken around 13 billion years to reach Earth.

“At these distances, you’re really looking back in time, like you have a time machine,” said Ray Villard, of the Space Telescope Science Institute in Baltimore. “Those things don’t exist anymore.”

The photo could be one of the ultimate achievements of the Hubble telescope, now almost twenty years old.

“These new observations are likely to be the most sensitive images Hubble will ever take,” said Professor Jim Dunlop of the University of Edinburgh.

The servicing mission in May extended the telescope’s life by around five years, but it is scheduled to be replaced by the James Webb Space Telescope in 2014. This will use infrared imaging and have a greater collecting area than Hubble, and it is thought that it may be able make out objects from just 100 million years after the Big Bang.

“We’ve really pushed Hubble to its limits,” said Villard, “and we need a bigger space telescope to go back even farther. It shows us there are really exciting things to look for with the Webb telescope.”
