Scientists find key human language gene

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.”

	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

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.

Scientists report chemotherapy cocktail may cause adult women to grow new egg cells

Chemotherapy is usually associated with a collection of side effects ranging from digestive problems to hair loss, but a study published this week in Human Reproduction demonstrated that female cancer patients may find they have something in common with much younger women in one specific area — their ovaries.

Scientists from the University of Edinburgh examined donated ovarian tissue from fourteen female cancer patients, most of whom had Hodgkin lymphoma, and compared it to tissue from healthy women. They found the samples from women who had been treated with a specific chemotherapeutic regimen known as ABVD not only contained greater numbers of dormant ova — egg cells — than those from women treated with harsher regimens but also more than samples from healthy women. ABVD is named for combining several drugs known as adriamycin, bleomycin, vinblastine, and dacarbazine.

These reproductive cells were not merely more plentiful in ABVD patients. They also appeared immature, “new” in the words of lead researcher Evelyn Telfer. This challenges the conventional belief that girls are born with all the ova they will ever have and the numbers can only go down as the cells are either used up by the reproductive cycle or succumb to damage or natural aging. However, further research is needed to confirm this. The study covered relatively few patients by scientific standards, and David Albertini of the Center for Human Reproduction in New York has suggested the cells may not actually be freshly grown. Instead, they may have always been there and were merely rendered more detectable by ABVD treatment.

The ability to grow new egg cells may have significant implications for women in Western societies, many of whom postpone childbearing to establish careers, sometimes into their late thirties or forties. However, Telfer warns against making use of these findings too soon: “There’s so much we don’t know about the ovary. We have to be very cautious about jumping to clinical applications.”

The experiments had been discussed earlier this year at the annual conference of the European Society of Human Reproduction and Embryology.

Nine dead after armed Santa Claus opens fire in LA suburb

Nine dead after armed Santa Claus opens fire in LA suburb

Posted on April 6, 2022April 7, 2022 by

Monday, December 29, 2008

At least nine people have been killed in a two-story house in Covina, California, after a man dressed in a full Santa Claus outfit opened fire at a Christmas Eve party and then set the house ablaze. Covina is a city in Los Angeles County, California about 22 miles (35 km) east of downtown Los Angeles.

According to local police, the Christmas party at the 1100 block of East Knollcrest Drive was attended by about 25 people. Trend News Agency said that the gunman fired two semi-automatic handguns and used an apparently home-made pressurized device to spread some kind of accelerant. As the guests tried in vain to escape, the gunman used his ‘present’ to spray inflammable liquid that started the raging blaze. Reports from the scene said Molotov cocktails were also used by the madman.

Media reports said the gunman was plotting vengeance against his ex-wife. Prime suspect, Bruce Jeffrey Pardo, age 45, six-foot-three-inch, 250 pound (1.9 meter, 113 kilogram), an electrical engineer, is long time Roman Catholic church usher and a laid-off aerospace worker. He worked with ITT Electronic Systems, Radar Systems, in Van Nuys from February 2005 to July 2008, and as an engineer at Northrop Grumman for five months in 2005, according to Court records. He had also worked for about nine years at NASA’s Jet Propulsion Laboratory in Pasadena until 1994.

Pardo’s ex-sister-in-law, who escaped from the Covina house alive with her injured daughter, called 911. Police on Friday released her 911 audio.

Msnbc.com has reported that Pardo “has brown hair and blue eyes, and known to frequent La Crescenta and La Verne.” Court records reveal that Mr Pardo’s wife acrimoniously divorced him last September. The divorce decree was finalized December 18. Until earlier this year, he lived in the Sylmar house with his ex-wife and her three children. The marriage lasted barely a year. However, Pardo held no criminal record and had no history of violence.

There is some speculation that the divorce may have been caused by Pardo concealing a paraplegic child from a previous relationship. Matthew, his nine-year-old son, by another former girlfriend, Elena Lucano, became brain damaged when he fell into a backyard swimming pool on Jan. 6, 2001. Pardo kept this child a secret from his wife. Pardo owed her $10,000 as part of the divorce settlement, according to court documents that detailed a bitter split. He also lost a dog he doted on and did not get back a valuable wedding ring. Pardo complained in a court declaration that Sylvia Pardo was living with her parents, not paying rent, and had spent lavishly on a luxury car, gambling trips to Las Vegas, meals at fine restaurants, massages and golf lessons.

After the mass murder, Pardo put on his street clothes and drove his rental Dodge Caliber car to the house of his brother, Jimmy Pardo, in Sylmar, approximately 30 miles away from the crime scene, where he committed suicide from a self-inflicted gunshot wound to the head. His brother was not present in the home and he broke inside to enter in. It was believed that Pardo intended to flee to Canada by plane as he had bought an airline ticket to a flight there from Los Angeles to Moline, Illinois. However due to suffering from severe third-degree burns on both arms stemming from the blaze, he decided to go against the initial plan.

Police had found $17,000 cling-wrapped on his legs inside a girdle, the car key, and his rental car that had been parked on Herrick Avenue, one block from his brother’s house, which had been rigged by remnants of his Santa suit that would ignite a flame and detonate the car with black powder if removed. Also recovered from the scene were four 13-round capacity handguns that were each empty, and at least 200 rounds of ammunition. Suggesting that what had been inside the car was being treated as a threat, police fired an incendiary device into it, destroying and burning it.

The police found on early Thursday, Mr Pardo bore a single gunshot wound to the head. According to LA County coroner’s official Ed Winter, the bodies found in the ashes were “extremely charred and burned.” All three of Sylvia Pardo’s children — Selina, Sal and Amanda — survived. According to the Scott Nord, the Ortega family lawyer, “the entire family was wiped out, and there’s basically like 16 orphans.”

Three other party guests have injuries, according to police. A 16-year-old girl was shot in the back, and an eight-year-old girl suffered facial gunshot wounds that were not life-threatening, while a 20-year-old woman had a broken ankle, after jumping from a second-story window, the police specified. About 80 firefighters put off the fire that soared fifteen metres (40 to 50 feet) high for more than one hour. The police discovered two handguns at the scene, and found two more in the in-laws’ house. Media reports on Friday said the 16-year-old daughter of Sylvia Pardo was released from Los Angeles County-USC Medical Center.

Meanwhile, investigators served a search warrant at Pardo’s Montrose house, where they retrieved evidence of high-octane racing fuel, five empty boxes for semi-automatic handguns, as well as two shotguns.

Covina police Lt. Pat Buchanan on Saturday said they are looking for Pardo’s rented gray 1999 RAV4, with California license plate 5RYD562. Police have found the second rental car Saturday night in a Glendale, California but found no bombs nor any explosives.

The police also revealed Saturday the names of nine people missing since the Christmas Eve massacre occurred. They are Pardo’s ex-wife, Sylvia Pardo, 43; her parents, Joseph Ortega, 80, and Alicia Ortega, 70; Alicia Ortiz, 46, and her son, Michael Ortiz, 17; Sylvia’s brother, Charles Ortega, 50, and his wife, Cheri, 45; another brother, James Ortega, 52, and his wife, Teresa, 51, according to Lt. Buchanan. “Hopefully, we’ll get positive identifications early next week,” Covina Police Chief Kim Raney said.

A murder-suicide is an act in which an individual kills one or more other persons immediately before, or at the same time as, killing him or herself. According to the psychiatrist Karl A. Menninger, murder-suicide or murder and suicide are interchangeable acts – suicide sometimes forestalling murder, and vice versa.

Christchurch can host 2011 Rugby World Cup final

Christchurch can host 2011 Rugby World Cup final

Posted on April 5, 2022April 6, 2022 by

Tuesday, November 14, 2006

Christchurch, New Zealand‘s Jade stadium says they can host the 2011 Rugby World Cup final if Auckland can’t make a decision on whether or not they should build a new stadium on the waterfront or upgrade Auckland’s current stadium, Eden Park, costing NZ$500 million and $385 million respectively.

Jade Stadium would be able to host the final if they were to include temporary seating to accommodate 60,000 people, required by the International Rugby Board (IRB).

Gary Moore, mayor of Christchurch, said that if they were selected to host the final then they will ask the government for $80 million. The stadium is already planning for an upgrade, worth $60 million but that money will be funded from private and charitable organisations as well as the local and central governments. The current upgrade will see Jade stadium’s seating capacity grow to 43,000 and if they host a quarter-final or semi-final then temporary seating will increase the seats to 55,000.

Trevor Mallard, the Minister of Sport, said that the Auckland City Council and the Auckland Regional Council have both been given about two weeks to tell the government which decision it supports. If they cannot come to a decision then the final will most likely be given to Jade stadium, Christchurch. The least likeliest of all decisions, an upgrade of Carlaw park, but that is designated for a retirement home and on private land.

Mr Moore said that he and “stadium officials had offered Jade Stadium as a back-up final venue at a recent informal meeting with Mallard because of the continuing Auckland divisions over a site. This is about New Zealand Inc, not about Christchurch versus Auckland. What we have said to Trevor Mallard is we are able to put a stadium into Christchurch that would accommodate the numbers they would need as an insurance policy if Auckland cannot get its act together. The Government knows that when Christchurch or Canterbury puts its hand up it delivers with excellence.”

Bryan Pearson, chief executive of Vbase, the company which manages Jade Stadium, said: “It was not uncommon for major sporting venues to add temporary seating for big events. London had included temporary seating for some stadiums as part of its successful Olympic hosting bid. It was not a low-rent option, and was a commercially prudent way to marry short-term opportunity with long-term legacy.”

Mr Pearson hopes that Jade Stadium will not be used for the final as he understands why the government wants a national stadium, “Let’s hope this gets sorted and we can focus our attentions on playing a very major supporting role. We are only a third the size of Auckland, so what we can sustain post-World Cup is nowhere near what Auckland can.”

Warwick Taylor, former All Black, said it will be great if Christchurch can host the final even though he played in the 1987 final at Eden Park. Though Mr Taylor does say that an Auckland stadium is a better idea as a 60,000 seat stadium is more viable in such a large population city. Mr Taylor said that he “had great memories playing at Eden Park and in some ways would hate to see it lose the final. But I also like the idea of a national stadium.”

The New Zealand Rugby Union said that a waterfront stadium and an upgrade of Eden Park are the only two options being considered, and no other stadiums are being considered.

A lot of people are confirming that Christchurch will be able to cope with the huge amount of visitors that would arrive for the final as Christchurch has the highest per capita amount of restaurants and bars in Australasia. The city also features numerous hotels.

If New Zealand cannot deliver a final in a 60,000 seat World Class stadium then the IRB will allocated the final to another country.

U.S. President Obama’s farewell address focuses on accomplishment

U.S. President Obama’s farewell address focuses on accomplishment

Posted on April 5, 2022April 6, 2022 by

Thursday, January 12, 2017

United States President Barack Obama gave his official farewell address on Tuesday night from McCormick Place in Chicago, reflecting on personal and national accomplishments. This is expected to be his last major speech before officially handing the reins to president-elect Donald Trump on January 20.

“Its why GIs gave their lives at Omaha Beach and Iwo Jima; Iraq and Afghanistan – and why men and women from Selma to Stonewall were prepared to give theirs as well.”

Obama’s speech was wide-ranging. He thanked his family and the nation, spoke of the need for unity, noted the country’s accomplishments and need for improvement in areas like education and civil rights, and spoke about the need for pride in U.S. accomplishments, citing milestones of U.S. history and of his presidency specifically. “It’s why GIs gave their lives at Omaha Beach and Iwo Jima; Iraq and Afghanistan – and why men and women from Selma to Stonewall were prepared to give theirs as well.”

The president also addressed his country’s troubled history with race and racism, an issue many black citizens feel he has avoided. Despite this, Chauncy Devega of Salon described the president as “a role model of calm, cool reflective black masculinity: a man utterly at home in his own skin.” Obama described the concept of a post-racial U.S. “unrealistic” and particularly cited the need for reform in education and the criminal justice system and greater acceptance of scientific evidence, particularly evidence supporting action to counteract climate change.

However, publications including The Washington Post and Salon have given particular focus to another aspect of the president’s address: the country’s increasing political tensions and controversies involving access to news and information, both accurate and inaccurate. “We become so secure and our bubbles,” said Obama, “that we start accepting only information, whether it’s true or not, that fits our opinions instead of basing our opinions on the evidence that is out there,” calling this trend “a third threat to our democracy.”

The Washington Post characterized Obama’s comment, “If every economic issue is framed as a struggle between a hard-working white middle class and an undeserving minority, then workers of all shades will be left fighting for scraps while the wealthy withdraw further into their private enclaves,” as a “not-so-subtle jab” at the campaign tactics of President-elect Donald Trump. The Telegraph describes Obama’s warnings about the need to protect democracy as “a thinly veiled slight to the divisive rhetoric of Donald Trump’s election campaign, which included attacks on Muslims, the disabled, women and immigrants.” The president went on to call on the public to “reject the first dawning of every attempt to alienate any portion of our country from the rest or to enfeeble the sacred ties that make us one America. We weaken those ties when we allow our political dialogue to become so corrosive […] We weaken those ties when we define some of us as more American than others when we write off the whole system as inevitably corrupt and when we sit back and blame the leaders we elect without examining our own role in electing them. It falls to each of us to be those anxious, jealous guardians of our democracy.”

Despite this, when the mention of Donald Trump brought boos from the crowd, Obama reiterated the importance of the long history of peaceful transfers of power from one president to the next: “No no no no no. […] I committed to President-elect Trump that my administration would ensure the smoothest possible transition, just as President Bush did for me.” However, this was not unaccompanied by a call to action. Near the end of the speech, he insisted citizens dissatisfied with elected officials should “lace up your shoes, grab a clipboard, get some signatures and run for office yourself.”

Overall, the departing president’s speech focused on accomplishment, echoing the “Yes we can” slogan from his 2008 campaign: “If I have told you eight years ago, that America would reverse a great recession, reboot our auto industry, and unleash the longest stretch of job creation in our history. If I had told you, that we would open up a new chapter with the Cuban people, shut down Iran’s nuclear weapons program without firing a shot, take out the mastermind of 9/11[…] If I had told you that we would win a marriage equality and secure the right to health insurance for another twenty million of our fellow citizens. If I had told you all that, you might have said our sights were set a little too high. But that’s what we did.”

But when the crowd began shouting “Four more years! Four more years!” Obama, with a small laugh, answered, “I can’t do that.”
