Researchers have found a crucial genetic difference between humans and chimps that could help explain our language and speech abilities. The difference lies in a gene called FOXP2 which encodes for a protein of the same name. This acts as a transcription factor, controlling the activity of other genes.

The human and chimp versions of the protein differ in only two of their 740 amino acid components, but when researchers at the University of California, Los Angeles, replaced the human gene with the chimp version in neurons grown in the laboratory, they found it affected the expression of at least 116 other genes.

The results are detailed in a paper published on Thursday in the scientific journal Nature.

Author of the study Dr. Daniel Geschwind, of the David Geffen School of Medicine at UCLA, said the gene had a “major role” in differences between chimps and humans. “We showed that the human and chimp versions of FOXP2 not only look different but function differently too.”

Some of the affected genes control the formation of connections in the brain, whilst others relate to facial movements. Several have already been found to be involved in language disorders. Mutations in FOXP2 itself were also known to affect speech and language; the gene was first identified in members of a family suffering from language problems who were found to share a genetic mutation.

Frances Vargha-Khadem at University College London has studied patients with FOXP2 mutations, and agrees with the new research. As well as language problems, some of her subjects have changes in the shape of their jaws, mouths and tongues. She thinks that chimps may also have these differences.

“We believe FOXP2 is not only important for the higher order cognitive aspect of language but also for the motor aspect of speech and language,” said Genevieve Konopka, one of the authors of the paper at UCLA.

Previous research indicates that the changes in FOXP2 occurred around 200,000 years ago with the rise of modern humans. Geschwind also suggests that several of the related genes may have evolved together. Preliminary studies have shown signs that they too emerged relatively recently.

Scientists are now keen to further study FOXP2 and the genes that it affects. Geschwind believes this could eventually lead to breakthroughs in treatment for disorders such as autism and schizophrenia, which affect language skills.

The study was funded by the National Institute of Mental Health, the A.P. Giannini Foundation and the National Alliance for Research on Schizophrenia and Depression.

Leaders from around the world have congratulated re-elected U.S. President Barack Obama on his success at the ballot box.

Israeli leader Benjamin Netanyahu stated that he “will continue to work with President Obama to preserve the strategic interests of Israel’s citizens” and described relations between the U.S. and Israel as “rock solid”. Some others within the ruling Likud party were not so optimistic about the relationship, with Knesset member Danny Danon criticising Obama for “ill-advised” policies towards Israel and hoping Obama “resets his course relating to Israel and our region for the next four years”.

A statement on behalf of Palestinian leader Mahmoud Abbas expressed hope that Obama “continues his efforts to achieve peace in the Middle East”.

The British Prime Minister David Cameron took time from his tour of the Middle East to congratulate Obama and listed as shared priorities a trade deal between the U.S. and the United Kingdom as well as solving the crisis in Syria. Ed Miliband, leader of the opposition Labour Party, stated on Twitter that Obama’s success in the election was “based on building fairer economy and optimism about what politics can achieve.”

French leader François Hollande said in choosing Obama over Mitt Romney, voters in the United States had voted for “an America of openness and solidarity, fully engaged on the international scene and conscious of the challenges facing our planet: peace, economy and the environment”. He listed economic growth, unemployment, and the Middle East as challenges the two politicians would have to face. German leader Angela Merkel stated she “deeply appreciated” meetings and conversations with Obama on issues including “overcoming the global financial and economic crisis”.

Herman Van Rompuy, President of the European Council, and Jose Manuel Barroso, President of the European Commission, issued a joint statement which described the U.S. as “a key strategic partner of the European Union” and hoped to meet Obama “at an early date in order to reconfirm our priorities and provide renewed impetus to our joint action”.

Across Africa, Obama received congratulations from South African President Jacob Zuma, Nigerian President Goodluck Jonathan, and Raila Odinga, the Prime Minister of Kenya.

Tensions are running high at the U.S. Postal Service as it faces an enormous budget shortfall. Even after announcing it was cutting 3,000 jobs, the beleaguered government agency is still quickly running out of money.

Postmaster General John Potter asked the United States Congress for help on Wednesday, once again bringing up the possibility of reducing mail delivery from six to five days a week. The service reduction would save approximately $3.5 billion this year.

Another way to cut costs could include changes to how it pays for its employee retirement plan, which would save a further $2 billion. Closing small and rural post offices is another possibility that has been discussed.

Many measures have already been taken to stem the agency’s losses. Construction of new facilities has been put on hold and existing ones put up for sale, millions of man-hours have been cut, and executive salaries have been frozen.

House Oversight Post Office Subcommmittee chairman Stephen F. Lynch (D-Mass.) has expressed reluctance with the plan to reduce service, saying “With the Postal Service facing budget shortfalls the subcommittee will consider a number of options to restore financial stability and examine ways for the Postal Service to continue to operate without cutting services.”

Other than cost cutting, Congress could also appropriate taxpayer dollars to fund the struggling Postal Service, which currently does not rely on public funding outside of a subsidy for international voting mail and services for the blind.

If nothing is done, the USPS will soon run completely out of money, and may be unable to pay many of its bills. Salaries are the agency’s highest priority to continue paying, though other debts may have to wait to be paid, said Potter. Last year the Postal Service lost $2.8 billion.

The Community Broadcasting Association of Australia (CBAA) has urged the Australian government to increase funding for community broadcasters. CBAA is asking for an extra $AU14 million for “vital community broadcasting services.”

According to CBAA President Deborah Welch, community television is the training ground for the Australian media industry.

“It is the launching pad for the career of thousands of Australian musicians. It is an incredible source of local news, music and culture targeted specifically to local communities and produced by members of the community themselves,” Ms Welch said in a statement.

Stations broadcast a range of programs from religious programing, to car shows and sporting events. Several state based sporting leagues broadcast on community television stations. C31 Melbourne broadcasts an association football show called The Victoria Football Show; Queensland Community Television broadcasts AFL Queensland State League matches; and C31 Adelaide broadcasts Indoor Cricket & Netball and South Australian National Football League matches.

According to the CBAA, the primary income sources for community television stations are sponsorship announcements and community donations.

“The CBBA is calling on the Federal Government to commit $14 million in new funding for content production, infrastructure, training and sector co-ordination and planning,” Ms Walch says. “With $10.4 billion being spent on ‘strengthening the economy’ this is highly targeted $14 million will assist in skills development and employment pathways for many volunteers involved in local stations as well as strengthening local communities ability to sustain themselves in tough times.”

Australian Greens communications spokesperson Senator Scott Ludlum says, “[The] government should always be looking at ways to bring communities together, through sharing information and building partnerships.”

In a major decision, the Supreme Court of the United States has expanded the right of government to seize private property for public good by allowing the city of New London, Connecticut to invoke eminent domain and seize homeowners’ property for economic development reasons.

In a closely-divided decision, 5-4, the court determined that the city’s economic development plan constituted a “public use”, and therefore qualified under the U.S. Constitution’s fifth amendment’s Eminent Domain clause.

Justice John Paul Stevens wrote the majority decision, and was joined by Justices David H. Souter, Ruth Bader Ginsburg, Stephen G. Breyer and Anthony Kennedy. “Promoting economic development is a traditional and long accepted function of government,” Stevens wrote, and justified the decision further by saying municipal authorities are better positioned to make decisions regarding a community’s best interests than judges.

Writing the dissenting opinion, Justice Sandra Day O’Connor rejected the economic justification as a public use, pointing out that wealthy individuals are more capable of defending themselves and so are less at risk. But the greatest issue was the liklihood of abuse of eminent domain:

“The specter of condemnation hangs over all property. Nothing is to prevent the state from replacing any Motel 6 with a Ritz-Carlton, any home with a shopping mall or any farm with a factory.” A separate dissent was also included written by Justice Clarence Thomas.

China has finished production of the first of its Chinese-built magnetically levitated (maglev) trains in Zhuzhou, Hunan. Described as low-cost and eco-friendly, the trains are to begin operating next year on the Daitai line between Haidian District and Beijing. The three-coached trains are able to carry up to 600 passengers and run at a top speed of 100 km/h.

“It’s ideal for mass transportation, as it is quiet and environmentally friendly”, says Xu Zongxiang, general manager of Zhuzhou Electric Locomotive Company. “Its manufacturing cost is about 75 percent of a conventional light-rail train”.

The train claims zero emissions as opposed to conventional trains which run on coal or diesel. It has a minimum turning radius of 50 meters and the production company has stated that it has reduced the risks of derailment and overturning. The company is exploring possible future operations in certain cities. Meanwhile, the Daitai line between Haidian District and Beijing is scheduled to operate by next year.

Liu Youmei, a railway transport specialist, said, “It can be used for public transport in populous areas and at scenic spots with fragile environment.”

China operates the first commercial maglev in the world, in Shanghai between a metro station and Pudong International Airport. The train takes less than 8 minutes to cover the 30 km route with a top speed of 430 km/h. Maglev trains can accelerate to high speeds as they run suspended in the air by magnetism, avoiding friction between the train and the tracks.
