US: Bluefin tuna probably OK after BP oil spill

(AP) ? Last year's BP oil spill probably won't push the troubled bluefin tuna population in the Gulf of Mexico over the edge as some scientists had worried, a federal analysis shows.

Of all the potential damage from the 172-million-gallon (651-million-liter) spill in April 2010, scientists had been most concerned about how the oil spill would harm an already overfished species of large tuna. That's because about one-fifth of the spawning habitat where the Gulf's baby tuna were living was coated with oil, according to satellite records. Tuna less than a year old are most vulnerable to pollution.

An analysis by the National Oceanic and Atmospheric Administration, using two different projections from computer models, says that at most, such a spill probably would result in a 4 percent reduction in future spawning of the fish, but probably far less.

Bluefish tuna is considered one of the Gulf's signature species. A summit that begins Monday in Houston will examine the Gulf's health, including the government's restoration plans and the tuna's fate.

"It appears so far that the impact on the larval population is relatively small," said Clay Porch, director of sustainable fisheries for NOAA's Southeast Fisheries Science Center in Miami.

The agency's analysis, which was mentioned in two pages of a 114-page government update on overall tuna health released in May, is based on an assumption that 1 in 5 baby tuna was killed or unable to reproduce in the future because that's the size of the spill in the spawning area.

That 20 percent potential loss of year-old tuna translates to 4 percent of the overall tuna population in the future. Overall population figures also have to factor in the fact that in general many baby tuna at that age die naturally.

But that is probably way too high a figure, Porch said in an interview.

Instead of 20 percent of baby tuna being harmed, more recent analysis yet to be published said it should be 11 percent or maybe even 5 percent, he said. Those figures should be reduced even more for the overall future population of tuna, down nearer to 2 percent.

At most that number should be 1 in 9 or even in 1 in 20 deaths of baby tuna, and that's only the effect on one year for the long-lived tuna.

Those smaller figures are based on larval surveys that have not been released publicly because of a potential court case with BP over damages from the spill, and more simulations "that are conditioned on real data," Porch said.

Porch said it's unlikely that the effect on tuna stock would hit 4 percent and "it is not an additional major source of stress" on the overall population of the bluefin tuna in the Gulf. Other work on baby tuna health will be published in peer reviewed science journals.

But that's only the young. So far NOAA doesn't know how the spill affected adults and whether adults of all ages were killed or made infertile in massive numbers that could have a bigger effect on the overall population than the oiling of one year's worth of young, Porch said.

Boris Worm, a fisheries professor at Dalhousie University in Canada who has warned of problems with tuna populations in the past, said the NOAA figures are within the yearly variations of mortality for tuna.

"So it will be a bad year, but not a catastrophic year," Worm said. "This wouldn't push them over the brink."

Former NOAA chief scientist Sylvia Earle, a renowned ocean explorer who has campaigned against overfishing of tuna, isn't convinced that bluefin tuna weathered the oil slick.

"I think it's too early to celebrate a possible greater survival than had been predicted. These are, after all, models," Earle said. "The truth is we don't have enough information to be able to clearly say one way or another what happened to the 2010 class of baby tuna."

Gulf scientists have wondered for months about the health of the bluefin tuna, said Larry McKinney, executive director of the Harte Research Institute for Gulf of Mexico Studies at Texas A&M University in Corpus Christi.

"They are sentinel species that gives us an idea of the health of the open ocean, where we don't know a lot," McKinney said.

Southern Miss ruins No. 7 Houston's BCS hopes

HOUSTON (AP) ? Austin Davis threw four touchdown passes and No. 24 Southern Mississippi ruined Houston's perfect season and Bowl Championship Series hopes with a 49-28 victory over the seventh-ranked Cougars on Saturday.

It was star quarterback Case Keenum's last home game for Houston for sure, and could've also been the finale for coach Kevin Sumlin, who has been mentioned as a top candidate for virtually every higher-profile job opening.

Houston (12-1) was poised to impress a national-television audience and representatives from the Orange and Sugar Bowl, who attended Saturday's game. Keenum could've also made one last case for an invitation to next week's Heisman Trophy ceremony.

Instead, the Golden Eagles (11-2) turned it into their big day, shackling Houston's high-powered offense and striking with several big plays of their own to win their first league title.

Mexico activist in Juarez women killings wounded (AP)

CIUDAD JUAREZ, Mexico ? An activist representing relatives of women slain or missing in the border city of Ciudad Juarez was shot Friday in what authorities called an apparent robbery attempt.

Chihuahua state prosecutors said Norma Andrade, 51, was shot twice outside her home and was in stable condition in a hospital.

Andrade was the second activist to be shot this week in northern Mexico. Anti-crime activist Nepomuceno Moreno was killed Monday in Hermosillo. He had protested the kidnapping of his teenage son.

Andrade founded an organization of relatives of women who have gone missing or been murdered in Ciudad Juarez to pressure authorities to solve the cases. Her daughter Lilia Alejandra Garcia Andrade was tortured, raped and killed in 2001 when she was 17.

Arturo Sandoval, spokesman for the state Attorney General's Office, said Andrade told investigators that a man approached her outside her house and tugged at her purse. When she tried to hold on to it, the man fired his gun wounding her right hand and left shoulder, Sandoval said.

Authorities were still trying to determine whether it was a robbery or a murder attempt, Sandoval said.

Andrade's daughter, Malu Andrade, told The Associated Press that teachers at the middle school where her mother works said suspicious men had been asking about her whereabouts Friday morning. The attack happened in the afternoon.

"Authorities knew that we had been threatened," the daughter said by telephone.

A series of eerily similar killings of more than 100 mainly young women began in Ciudad Juarez in 1993, but appeared to had tapered off by late 2004 or early 2005.

The killings have been the topic of books, documentaries and the 2006 movie "Bordertown" starring Jennifer Lopez. Lopez in 2007 received a special recognition from Andrade and her organization, Bring Our Daughters Home.

Rise of atmospheric oxygen more complicated than previously thought

Friday, December 2, 2011

The appearance of oxygen in the Earth's atmosphere probably did not occur as a single event, but as a long series of starts and stops, according to an international team of researchers who investigated rock cores from the FAR DEEP project.

The Fennoscandia Arctic Russia - Drilling Early Earth Project -- FAR DEEP -- took place during the summer of 2007 near Murmansk in the northwest region of Russia. The project, part of the International Continental Scientific Drilling Program, drilled a series of shallow, two-inch diameter cores and, by overlapping them, created a record representing stone deposited during the Proterozoic Eon -- 2,500 million to 542 million years ago.

"We've always thought that oxygen came into the atmosphere really quickly during an event," said Lee R. Kump, professor and head of geosciences, Penn State. "We are no longer looking for an event. Now we are looking for when and why oxygen became a stable part of the Earth's atmosphere."

The researchers report in today's (Dec. 1) issue of ScienceExpress that evaluation of these cores and comparison with cores from Gabon previously analyzed by others, supports the conclusion that the Great Oxidation Event played out over hundreds of millions of years. Oxygen levels gradually crossed the low atmospheric oxygen threshold for pyrite -- an iron sulfur mineral -- oxidation by 2,500 million years ago and the loss of any mass-independently fractionated sulfur by 2,400 million years ago. Then oxygen levels rose at an ever-increasing rate through the Paleoproterozoic, achieving about 1 percent of the present atmospheric level.

"The definition of when an oxygen atmosphere occurred depends on which threshold you are looking for," said Kump. "It could be when pyrite becomes oxidized, when sulfur MIF disappears or when deep crustal oxidation occurs."

When the mass-independent fractionated sulfur disappeared, the air on Earth was still not breathable by animal standards. When red rocks containing iron oxides appeared 2,300 million years ago, the air was still unbreathable.

"At about 1 percent oxygen, the groundwater became strongly oxidized, making it possible for groundwater seeping through rocks to oxidize organic materials," said Kump.

Initially, any oxygen in the atmosphere, produced by the photosynthesis of single-celled organisms, was used up when sulfur, iron and other elements oxidized. When sufficient oxygen accumulated in the atmosphere, it permeated the groundwater and began oxidizing buried organic material, oxidizing carbon to create carbon dioxide.

The cores from the FAR-DEEP project were compared with the Francevillian samples from Gabon using the ratio of carbon isotopes 13 and 12 to see if the evidence for high rates of oxygen accumulation existed worldwide. Both the FAR-DEEP project's cores and the Francevillian cores show large deposits of carbon in the form of fossilized petroleum. Both sets of cores also show similar changes in carbon 13 through time, indicating that the changes in carbon isotopes occurred worldwide and oxygen levels throughout the atmosphere were high.

"Although others have documented huge carbon isotope variations at later times in Earth history associated with stepwise increases in atmospheric oxygen, our results are less equivocal because we have many lines of data all pointing to the same thing," said Kump. "These indications include not only carbon13 isotope profiles in organic mater from two widely separated locations, but also supporting profiles in limestones and no indication that processes occurring since that time have altered the signal."

Justin Bieber and Friends Help Light Rockefeller Center Christmas Tree


Let's face it: this is Justin Bieber's world. We merely live in it.

The superstar has been everywhere this holiday season, and not solely because some moron named Mariah Yeater sued him for paternity of her son. Bieber has released a Christmas CD and has spent weeks promoting it via talk shows, live performances and official video releases. The latest example of the latter? This duet with Mariah Carey.

So it's only appropriate that Bieber - along with friends Usher and Busta Rhymes - was featured on last night's tree lighting ceremony at Rockefeller Center in New York City. Watch the teenage icon do his thing in the following two performance videos:

Hillary Rodham Clinton Makes Historic Visit To Myanmar

NAYPYIDAW, Myanmar -- U.S. Secretary of State Hillary Rodham Clinton has begun a historic visit to the long-isolated Southeast Asian nation of Myanmar to test the country's first civilian government in decades on its commitment to reform, including severing military and nuclear ties with North Korea.

Clinton arrived Wednesday in the capital of Naypyidaw on the first trip by a U.S. secretary of state to the nation also known as Burma in more than 50 years. She is to meet senior Myanmar officials Thursday before heading to the commercial capital of Yangon, where she will see opposition leader and Nobel peace laureate Aung San Suu Kyi, who is returning to the political scene after years of detention and harassment.

"I am obviously looking to determine for myself and on behalf of our government what is the intention of the current government with respect to continuing reforms both political and economic," Clinton told reporters before her arrival here.

She declined to discuss the specific measures she would suggest or how the U.S. might reciprocate.

"We and many other nations are quite hopeful that these flickers of progress ... will be ignited into a movement for change that will benefit the people of the country," she said, echoing President Barack Obama when he announced he was sending her to Myanmar.

The Obama administration is betting that the visit will pay dividends, promoting human rights, limiting suspected cooperation with North Korea on ballistic missiles and nuclear activity and loosening Chinese influence in a region where America and its allies are wary of China's rise.

Officials say Clinton will be seeking assurances from Myanmar's leaders that they will sign an agreement with the U.N. nuclear watchdog that will permit unfettered access to suspected nuclear sites. The U.S. and other Western nations suspect Myanmar has sought and received nuclear advice along with ballistic missile technology from North Korea in violation of U.N. sanctions. A U.S. official said missiles and missile technology are of primary concern but signs of "nascent" nuclear activity are also worrying.

Clinton also will note the government's baby steps toward democratic reform after 50 years of military rule that saw brutal crackdowns on pro-democracy activists like Suu Kyi and members of her National League for Democracy party.

Clinton's private dinner on Thursday and formal meeting with Suu Kyi on Friday probably will be the highlights of the visit. Suu Kyi, who intends to run for parliament in upcoming elections, has welcomed Clinton's trip and told Obama in a phone call earlier this month that engagement with the government would be positive. Clinton has called Suu Kyi a personal inspiration.

The trip is the first major development in U.S.-Myanmar relations in decades and comes after the Obama administration launched a new effort to prod reforms in 2009 with a package of carrot-and-stick incentives.

One senior official accompanying Clinton on the trip described the administration's early efforts as "abysmal failures" but said the situation had improved notably in recent months. The official spoke on condition of anonymity in order to discuss the administration's internal thinking.

The rapprochement sped up when Myanmar held elections last year that gave power to a new government that pledged greater openness. The administration's special envoy to Myanmar has made three trips to the country in the past three months, and the top U.S. diplomat for human rights has made one.

Those officials pushed for Clinton to make the trip, deeming a test of the reforms as worthwhile despite the risks of backsliding.

President Thein Sein, a former army officer, has pushed reforms forward after Myanmar experienced decades of repression under successive military regimes that canceled 1990 elections that Suu Kyi's National League for Democracy party won.

Last week, Myanmar's parliament approved a law guaranteeing the right to protest, which had not previously existed, and improvements have been made in areas such as media and Internet access and political participation. The NLD, which had boycotted previous flawed elections, is now registered as a party.

But the government that took office in March is still dominated by a military-proxy political party, and Myanmar's commitment to democratization and its willingness to limit its close ties with China are uncertain.

Corruption runs rampant, hundreds of political prisoners are still jailed and violent ethnic conflicts continue in the country's north and east. Human rights activists have said Clinton's visit should be judged on improvements in those conditions.

Myanmar's army continues to torture and kill civilians in campaigns to stamp out some of the world's longest-running insurgencies, according to rights groups. They say ongoing atrocities against ethnic minorities serve as a reminder that reforms recently unveiled by the country's military-backed government to worldwide applause are not benefitting everyone.

Aid groups have reported atrocities that occurred as recently as last month: A village leader was killed, allegedly by soldiers, for helping a rebel group, his eyes gouged out and his 9-year-old son buried beside him in a shallow grave. The boy's tongue was cut out.

With minorities making up some 40 percent of Myanmar's 56 million people and settled in some of its most resource-rich border regions, resolution of these brutal conflicts is regarded by all sides as crucial. The fighting has uprooted more than 1 million people, now refugees within their country or in neighboring Thailand and Bangladesh.

And, although the government suspended a controversial Chinese dam project earlier this year, China laid down a marker ahead of Clinton's trip by having its vice president meet the head of Myanmar's armed forces on Monday.

China's Foreign Ministry said in a statement that Vice President Xi Jinping pledged to maintain strong ties with Myanmar and encouraged Gen. Min Aung Hlaing to push for solutions to unspecified challenges in relations.

Myanmar also remains subject to tough sanctions that prohibit Americans and U.S. companies from most commercial transactions in the country.

U.S. officials say Clinton's trip is a fact-finding visit and will not result in an easing of sanctions. But officials also say that such steps could be taken if Myanmar proves itself to be serious about reform. Other steps being contemplated include upgrading diplomatic relations that would see the two countries exchange ambassadors.

Despite high hopes, U.S. officials remain decidedly cautious about prospects for Clinton's visit. That caution has been echoed by some members of Congress, who have expressed concern that the trip is an undeserved reward for the regime.

"I am concerned that the visit of the secretary of state sends the wrong signal to the Burmese military thugs that cosmetic actions ... are sufficient for the U.S. to engage the regime," said Rep. Ileana Ros-Lehtinen, R-Fla., chairwoman of the House Foreign Affairs Committee. "Secretary Clinton's visit represents a monumental overture to an outlaw regime whose DNA remains fundamentally brutal."

Sen. Richard Lugar, R-Ind., the ranking member of the Senate Foreign Relations Committee, and Rep. Ed Royce, D-Calif., urged Clinton to make Myanmar's dealings with North Korea a top priority of her trip.
