Death toll in Tanzania building collapse rises to 17

NAIROBI (Reuters) - The death toll from the collapse of a building in Tanzania's commercial capital Dar es Salaam has climbed to 17, a senior government official said on Saturday.

The building of more than 12 storeys, which had been under construction, collapsed on Friday morning near a mosque in the Kariakoo district around the city centre. Several cars were crushed by falling masonry.

Tanzania's buoyant economy has fuelled a building boom, especially in Kariakoo and the city centre. But the speed of construction has raised concerns about standards.

"I can confirm that so far 17 people have been killed and their bodies have already been recovered," Dar es Salaam Regional Commissioner Said Meck Sadick told Reuters.

State television carried the same figure after conflicting reports on Friday about the death toll.

"Eighteen people survived the collapse of the building, but the search for more survivors continues," Sadick said, adding that the rescue operation had run through the night and would continue until everyone was accounted for.

"There is still a lot of work to be done," he said. "There is a lot of rubble that still has to be removed."

Witnesses said they believed construction workers were inside the building when it collapsed, and up to four boys who had been playing soccer at the nearby mosque were missing.

Tanzanian President Jakaya Kikwete, who visited the scene on Friday, ordered authorities to take action against responsible parties. Police officials said four suspects had been arrested, including the building owner and contractor.

Senate group resolves key issues on immigration reform: lawmakers

By Thomas Ferraro and Steve Holland

WASHINGTON (Reuters) - With U.S. business and labor now in agreement, a bipartisan group of senators has resolved all major issues in a pending deal to overhaul the U.S. immigration system and aims to unveil it after Congress reconvenes in the second week of April, key lawmakers said on Sunday.

The lawmakers said that while there was no final deal yet, they hope and even expect there to be one soon after the measure is put into legislative language so all eight senators in the group can review it.

The U.S. Chamber of Commerce, the biggest U.S. business group, and the AFL-CIO, the largest labor federation, reached an elusive agreement on a guest-worker program on Friday, clearing the way for the writing of a full bill.

The bill will include an earned pathway to U.S. citizenship for an estimated 11 million undocumented immigrants, bolstered border security and ways for business to meet the need for both high-skilled and low-skilled workers.

"With the agreement between business and labor, every major policy issue has been resolved," said Senator Charles Schumer, a New York Democrat and a member of the so-called Gang of Eight, which has four Democrats and four Republicans.

"We've all agreed that we're not going to come to a final agreement until we see draft legislative language and we agree on that," Schumer told NBC's "Meet the Press."

But Schumer added: "I don't think any of us expect there to be problems."

Republican Senator Jeff Flake of Arizona, another member of the group, also appeared on "Meet the Press," and said: "We're committed to this if we can get the language right."

Republican Senator Lindsey Graham of South Carolina, another member of the group, said: "I think we've got a deal."

"There are a few details yet," he said on CNN's "State of the Union" program. "But conceptually we have an agreement between business and labor, between ourselves that has to be drafted. It will be rolled out next week."

CONFIDENCE

Graham voiced confidence that the bill would eventually be approved by the Democratic-led Senate and Republican-led House of Representatives - provided President Barack Obama, as expected, actively rallies support for it.

The Gang of Eight had initially planned to have a bill by the end of March but now plans to unveil it in the week of April 8, when Congress returns from a two-week recess.

Republican Senator Marco Rubio of Florida, another member of the Gang of Eight and a potential 2016 White House contender, said the senators had made "substantial progress" on a deal, but were not yet finished.

"I'm encouraged by reports of an agreement between business groups and unions on the issue of guest workers. However, reports that the bipartisan group of eight senators have agreed on a legislative proposal are premature," Rubio said in a statement issued by his office.

Still, Rubio said: "I believe we will be able to agree on a legislative proposal that modernizes our legal immigration system, improves border security and enforcement and allows those here illegally to earn the chance to one day apply for permanent residency contingent upon certain triggers being met."

Rubio, the son of Cuban immigrants, made it clear that he expects a lengthy legislative process.

"We will need a healthy public debate that includes committee hearings and the opportunity for other senators to improve our legislation with their own amendments," he said.

Republicans have complained that a pathway toward U.S. citizenship would amount to "amnesty" and attract even more undocumented immigrants into the United States.

But members of the Gang of Eight have voiced confidence that the "earned pathway" toward citizenship that they drafted, which includes a requirement that immigrants pay a fine, pay back taxes and learn English, will attract Republican support.

"I hope that we can pull some Republicans our way. I think a number of them are with us already," Flake said.

Schumer served as a mediator in a conference call on Friday between the head of the U.S. Chamber of Commerce, Tom Donohue, and the president of the AFL-CIO, Richard Trumka, a source said.

A guest-worker program has been a major stumbling block to the Gang of Eight, which has been working to try to reach a deal since December. The thorny issue has derailed other immigration-reform efforts over the years.

Labor unions have argued against such a program, worrying that a flood of low-wage immigrant laborers would take away jobs from Americans. The agreement covers pay levels for low-skilled workers and provides labor protections for American workers.

A new "W visa" would be created for employers to petition for foreign workers in lesser-skilled, non-seasonal non-agricultural occupations. This could include jobs in hospitality, janitorial, retail, construction and others.

The W visa would not be considered a temporary visa, as workers would have the ability to seek permanent status after a year, according to details of the agreement released by the AFL-CIO.

The program would begin on April 1, 2015, unless there is a need to extend the start date by six months.

At the beginning, 20,000 visas would be permitted and the figure would rise to 35,000 the next year, 55,000 in the third year and 75,000 in the fourth. Under the agreement, the number of visas permitted in any year can never be less than 20,000 or more than 200,000.

The Gang of Eight began forming a day after the November 2012 elections, which saw Hispanics, the fastest growing voter bloc, heavily favor Democrats over Republicans.

The election experience has made Republicans realize that for their own political good they need to get behind immigration reform, something that has been primarily embraced by Democrats.

US commandos hand over troubled area to Afghans

KABUL, Afghanistan (AP) ? U.S. special operations forces handed over their base in a strategic district of eastern Afghanistan to local Afghan special forces on Saturday, a senior U.S. commander said. The withdrawal satisfies a demand by Afghan President Hamid Karzai that U.S. forces leave the area after allegations that the Americans' Afghan counterparts committed human rights abuses there on U.S. orders.

The transfer of authority ends a particularly rocky episode in the strained relations between the U.S. and Karzai. He had insisted that U.S. forces leave Nirkh district in Wardak province over the alleged torture, kidnapping and summary execution of militant suspects there ? charges U.S. officials firmly denied.

The incident shows the larger struggle of Karzai's government to assert its authority over security matters, even as its green security forces try to assume control of much of the country from coalition forces on a rushed timeline, ahead of the scheduled withdrawal of most of coalition forces by December 2014.

"We're coming out of Nirkh," said Maj. Gen. Tony Thomas, the top U.S. special operations commander in Afghanistan, in an interview with The Associated Press.

Attaullah Khogyani, spokesman for the governor of Wardak province outside Kabul, confirmed that U.S. special operations forces withdrew and were replaced by a joint Afghan security forces team.

Karzai had originally demanded the U.S. special operations forces pull out from the entire province, a gateway and staging area for Taliban and other militants for attacks on the capital Kabul. But he scaled down his demands to just the single district after negotiations with top commander in Afghanistan Gen. Joseph Dunford and other U.S. officials.

"President Karzai was specific, it's only for Nirkh, that was a provocative point," Thomas said. "American special operations forces are integral in the defense of Wardak from now until the foreseeable future."

U.S. commandos will also continue to visit the Afghan team in Nirkh.

"We're going to support them from a distance," Thomas said. "The reality is there was such a groundswell of support (from locals) in Wardak after the initial allegations that we're keeping several teams down there to work with the Afghan security forces for the future, with an idea that we'll transition over time."

The American special operations troops are paired with and live alongside locally recruited and trained teams known as Afghan local police. Thomas said most of the local police will be paired with Afghan security forces by the end of the summer, with the Americans making occasional visits as they will do in Nirkh, to assess whether they need logistic or other support.

One Wardak government official expressed relief that the agreement crafted with Karzai did not mean the complete pullout of U.S. forces from the province, saying that local officials were worried their new forces would not yet be able to keep hardcore insurgents out of the area.

The official spoke on condition of anonymity because his comments run counter to public statements made by Karzai that the Afghan security forces are ready for complete independence in Wardak.

Meanwhile, Taliban militants attacked a police convoy Saturday morning in Ghazni province in eastern Afghanistan, kicking off a fierce gun battle, according to deputy provincial police chief Col. Mohammad Hussain.

The police requested a coalition air strike, which hit the militants' position and killed 15 fighters but also wounded nine civilians including a woman and child, Hussain said. He did not report any police casualties.

Mate choice in mice is heavily influenced by paternal cues

Friday, March 29, 2013

Mate choice is a key factor in the evolution of new animal species. The choice of a specific mate can decisively influence the evolutionary development of a species. In mice, the attractiveness of a potential mate is conveyed by scent cues and ultrasonic vocalizations. Researchers from the Max Planck Institute for Evolutionary Biology in Pl?n investigated whether house mice (Mus musculus) would mate with each other even if they were from two populations which had been separated from each other for a long time period. To do this, the researchers brought together mice from a German population and mice from a French population. Although to begin with all the mice mated with one another randomly, the hybrid offspring of French and German parents were distinctly more choosy: they showed a definite preference for mating with individuals from their father's original population. According to the researchers, this paternal imprinting accelerates the divergence of two house mouse populations and thus promotes speciation.

In allopatric speciation, individuals of a species become geographically isolated from each other by external factors such as mountains or estuaries. Over time, this geographic separation leads to the sub-populations undergoing various mutations, and thus diverging genetically. Animals from the two different sub-populations can no longer successfully reproduce, so two new species evolve.

To find out what role partner selection plays in such speciation processes, Diethard Tautz from the Max Planck Institute for Evolutionary Biology and his colleagues conducted a comprehensive study on house mice ? the classic model organisms of biology. "To investigate whether there are differences in the mating behaviour of the mice in the early stages of speciation, we caught wild house mice in southern France and western Germany. The two populations have been geographically separate for around 3,000 years, which equates to some 18,000 generations," says Diethard Tautz. Due to this geographical separation, the French and German mice were genetically different.

The Pl?n-based researchers created a semi-natural environment for their investigations ? a sort of "Playboy Mansion" for mice. The research enclosure was several square meters in size and was divided up using wooden walls, "nests" made out of plastic cylinders, and plastic tubes. It also featured an escape tube with several entrances, which led into a cage system nearby. "We constructed the enclosure in such a way that all animals had unimpeded access to all areas, but thanks to the structural divisions were also able to create their own territories or retreat into nests," explains Tautz. "The escape tube was a control element. If the mice retreated to it only very seldom ? as was the case in our experiment ? then we could be sure there was no overpopulation in the central enclosure."

In this central enclosure, the French and German mice had both time and space to mate with each other and reproduce. "At first, all the mice mated with each other quite randomly. But with the first-generation offspring, a surprising pattern emerged," says Tautz. When the first-generation hybrid offspring of mixed French and German parentage mated, they showed a specific preference for pure-bred mates whose "nationality" was that of their father only. "There must be some kind of paternal influence that prompts the hybrid mice to choose a mate from a specific population, namely that of their father," concludes the biologist, based on the results of his study. "This imprinting must be learned, however, meaning that the animals must grow up in the presence of their fathers. This was not the case for the original mice, which were kept in cages for a time after being caught."

"We know that mice use ultrasonic vocalizations to communicate with each other and that particularly in the case of male mice these vocalizations can reveal signals of individuality and kinship. We believe that, like birdsong, the vocalizations of the males have a learned component and a genetic component," says Tautz. Therefore, French and German mice really could "speak" different languages, partly learned from their fathers, partly inherited from them. Individual mice thus have a mating preference for mice that speak the same language as they do.

The French and German mouse populations had evidently been geographically separated long enough for preliminary signs of species differentiation to be apparent as regards mating preferences. In addition, another aspect of mating behavior also sped up the speciation process.

Although mice have multiple mates, the researchers found evidence of partner fidelity and inbreeding. The tendency to mate with relatives fosters the creation of genetically uniform groups. When both occur together, this accelerates the speciation process.

In a next step, Diethard Tautz wants to find out whether the vocalizations of the mice play the decisive role in paternal imprinting, or if scent cues are also involved. Furthermore, the biologist wants to identify the genes that are involved in mate selection.

How diabetes drug delays aging in worms

Mar. 28, 2013 ? A widely prescribed type 2 diabetes drug slows down the aging process by mimicking the effects of dieting, according to a study published today using worms to investigate how the drug works.

Following a calorie-restricted diet has been shown to improve health in later life and extend lifespan in a number of animals, ranging from the simple worm to rhesus monkeys. The type 2 diabetes drug metformin has been found to have similar effects in animals but until now it was not clear exactly how the drug delays the aging process.

Researchers supported by the Wellcome Trust and Medical Research Council looked at the effects of metformin on C. elegans worms that were grown in the presence of E. coli bacteria, a relationship similar to that which humans have with the 'healthy' bacteria in our gut. They found that the worms treated with metformin lived longer only when the E. coli strain they were cultured with was sensitive to the drug.

Dr Filipe Cabreiro from the Institute of Healthy aging at UCL, who led the research, explains: "Overall, treatment with metformin adds up to 6 days of life for the worm which is equivalent to around a third of its normal lifespan. It seems to work by altering metabolism in the bacteria that live in the worm, which in turn limits the nutrients that are available to the worm host and has a similar effect to restricting the diet."

Bacteria living in the gut have an important role in helping the host organism to digest and extract nutrition from food. Defects in gut bacteria have been linked to metabolic diseases such as obesity, diabetes, inflammatory bowel disease and cancer. It has also been suggested that gut bacteria may have an impact on the aging process, but this is the first study to suggest a mechanism for how this works.

The team used strains of E. coli with defects in genes that are linked to metabolism and tweaked the levels of nutrients available to tease out which metabolic pathways might be affected by the drug. They found that treatment with metformin disrupted the bacteria's ability to metabolise folate, a type of B-vitamin, and methionine, one of the building blocks of proteins. This limits the nutrients that are available to the worm and mimics the effects of dietary restriction to enable the worms to live longer.

However, when they added an excess of sugar to the diet, the team found that the life-extending effects of metformin were cancelled out. As the drug is used as a treatment for diabetes caused by elevated glucose levels in the blood, this finding is particular relevant for understanding how the drug works in people.

Professor David Gems, who directed the study, said: "We don't know from this study whether metformin has any effect on human aging. The more interesting finding is the suggestion that drugs that alter bacteria in the gut could give us a new way of treating or preventing metabolic diseases like obesity and diabetes."

Metformin is currently one of the most widely prescribed drugs and the findings should help to inform how it is used in patients.

US consumer spending, income jump in February

WASHINGTON (AP) ? U.S. consumers stepped up spending in February after their income jumped, aided by a stronger job market that offset some of the drag from higher taxes. The gains led economists to predict stronger economic growth at the start of the year.

Consumer spending rose 0.7 percent in February from January, the Commerce Department said Friday. It was the biggest gain in five months and followed a revised 0.4 percent rise in January, which was double the initial estimate.

Americans were able to spend more because their income rose 1.1 percent last month. That followed huge swings in the previous two months, which reflected a rush to pay bonuses and dividends in December before taxes increased.

After-tax income also increased 1.1 percent last month, allowing consumers to put a little more away. The saving rate increased to 2.6 percent of after-tax income, up from 2.2 percent in January.

The gains in spending and income follow other signs of an economy gathering momentum. Hiring is up, businesses are spending more, the stock market is hitting record levels and the housing recovery is strengthening.

More spending by consumers should boost economic growth in the January-March quarter after a lull at the end of last year. Consumer spending accounts for 70 percent of economic activity.

After seeing Friday's report on consumer spending, Paul Ashworth, chief U.S. economist at Capital Economics, raised his growth forecast for the first quarter by a full percentage point. Ashworth now expects growth in the January-march quarter increase to an annual rate of 3 percent.

Growth at that pace would be a vast improvement from the 0.4 percent rate in the October-December quarter, which was held back by slower company stockpiling and the sharpest defense cuts in 40 years.

Ashworth called the boost in spending "impressive," noting that consumers spent more while having to adjust to the higher Social Security taxes and a spike in gasoline prices.

"We're now likely to see the fastest quarterly gain in real consumption in two years," he said.

Jennifer Lee, senior economist at BMO Capital Markets, said the increases suggest consumer spending could be growing in the first quarter at an annual rate of more than 3 percent. That would be the fastest gain in more than three years and more than double the 1.3 percent rate in the fourth quarter.

Inflation, as measured by a gauge tied to consumer spending, increased 1.3 percent in February compared with a year ago. That's well below the Federal Reserve's 2 percent target, giving the central bank room to keep stimulating the economy without having to worry about price pressures.

Consumers spent more at the start of the year even after paying higher taxes. An increase in Social Security taxes has reduced take-home pay for nearly all Americans receiving a paycheck. And income taxes have risen on the highest earners. The tax increases both took effect on Jan. 1.

One reason the tax increases haven't slowed the economy is companies have accelerated hiring and are slowly but steadily increasing wages.

Employers have added an average of 200,000 jobs a month since November. That helped lowered the unemployment rate in February to a four-year low of 7.7 percent. Economists expect similar strong job gains in March.

Businesses are also investing more in equipment and machinery, which has given factories a lift after a disappointing 2012.

And the housing recovery that began last year appears to be sustainable. In February, sales of previously occupied homes rose to the highest level in more than three years. The gains have helped lift home prices, which have made Americans feel wealthier.

Stock prices have also surged. On Thursday, the Standard & Poor's 500 index closed at a record high of 1,569. That surpassed the previous record of 1,565 set in October 2007, a year before the peak of the financial crisis.

Three weeks ago, the Dow Jones industrial average beat its 2007 record.

Markets are closed Friday for the Good Friday holiday.

Scientists image deep magma beneath Pacific seafloor volcano

Mar. 27, 2013 ? Since the plate tectonics revolution of the 1960s, scientists have known that new seafloor is created throughout the major ocean basins at linear chains of volcanoes known as mid-ocean ridges. But where exactly does the erupted magma come from?

Researchers at Scripps Institution of Oceanography at UC San Diego now have a better idea after capturing a unique image of a site deep in the Earth where magma is generated.

Using electromagnetic technology developed and advanced at Scripps, the researchers mapped a large area beneath the seafloor off Central America at the northern East Pacific Rise, a seafloor volcano located on a section of the global mid-ocean ridges that together form the largest and most active chain of volcanoes in the solar system. By comparison, the researchers say the cross-section area of the melting region they mapped would rival the size of San Diego County.

Details of the image and the methods used to capture it are published in the March 28 issue of the journal Nature.

"Our data show that mantle upwelling beneath the mid-ocean ridge creates a deeper and broader melting region than previously thought," said Kerry Key, lead author of the study and an associate research geophysicist at Scripps. "This was the largest project of its kind, enabling us to image the mantle with a level of detail not possible with previous studies."

The northern East Pacific Rise is an area where two of the planet's tectonic plates are spreading apart from each another. Mantle rising between the plates melts to generate the magma that forms fresh seafloor when it erupts or freezes in the crust.

Data for the study was obtained during a 2004 field study conducted aboard the research vessel Roger Revelle, a ship operated by Scripps and owned by the U.S. Navy.

The marine electromagnetic technology behind the study was originally developed in the 1960s by Charles "Chip" Cox, an emeritus professor of oceanography at Scripps, and his student Jean Filloux. In recent years the technology was further advanced by Steven Constable and Key. Since 1995 Scripps researchers have been working with the energy industry to apply this technology to map offshore geology as an aid to exploring for oil and gas reservoirs.

"We have been working on developing our instruments and interpretation software for decades, and it is really exciting to see it all come together to provide insights into the fundamental processes of plate tectonics," said Constable, a coauthor of the paper and a professor in the Cecil H. and Ida M. Green Institute of Geophysics and Planetary Physics at Scripps. "It was really a surprise to discover that melting started so deep in the mantle -- much deeper than was expected."

Key believes the insights that electromagnetics provides will continue to grow as the technology matures and data analysis techniques improve (last week Key and his colleagues announced the use of electromagnetics in discovering a magma lubricant for the planet's tectonic plates).

"Electromagnetics is really coming of age as a tool for imaging the earth," said Key. "Much of what we know about the crust and mantle is a result of using seismic techniques. Now electromagnetic technology is offering promise for further discoveries."

Key also has future plans to apply electromagnetic technology to map subglacial lakes and groundwater in the polar regions.

In addition to Key and Constable, coauthors of the paper include Lijun Liu of the University of Illinois and Anne Pommier of Arizona State University.

The study was supported by the National Science Foundation and the Seafloor Electromagnetic Methods Consortium at Scripps.

Kerry arrives in Iraq on unannounced visit

BAGHDAD (AP) ? U.S. Secretary of State John Kerry is in Iraq on an unannounced visit to urge Iraqi leaders to stop Iranian overflights of arms and fighters heading to Syria and to overcome sectarian differences that still threaten Iraqi stability 10 years after the American-led invasion that toppled Saddam Hussein.

Kerry flew into Baghdad on Saturday from Amman after accompanying President Barack Obama to Israel, the Palestinian Authority and Jordan.

Officials traveling with him said he would press Iraqi Prime Minister Nouri al-Maliki and other senior officials on democratic reforms and directly urge them to stop overflights of Iranian aircraft carrying military personnel and equipment to support the Syrian government as it battles rebels.

The overflights have long been a source of contention between the U.S. and Iraq and Kerry will tell the Iraqis that allowing them to continue will make the situation in Syria worse and threaten Iraq's stability.

A senior U.S. official said the sheer number of overflights, which occur "close to daily," as well as overland shipments to Syria through Iraq from Iran was inconsistent with Iranian claims that they are only carrying humanitarian supplies. The official said it was in Iraq's interest to prevent the situation in Syria from deteriorating further, particularly as there are fears that Iranian-backed extremists may gain a foothold in the country.

The official said there are clear links between al-Qaida linked extremists operating in Syria and militants who are carrying out terrorist attacks in Iraqi territory with increasing regularity.

Former Secretary of State Hillary Rodham Clinton secured a pledge from Iraq to inspect the flights last year, but the official said that since then only two aircraft have been checked by Iraqi authorities.

Kerry will tell al-Maliki that Iraq cannot be part of the political discussion about Syria's future until it clamps down on the shipments.

As Iraq approaches provincial elections next month, Kerry will also stress the importance of ensuring that all elements of society feel enfranchised, the official said. A recent decision to delay the polls in Anbar and Nineveh provinces is a "serious setback" to Iraq's democratic institutions and should be revisited, the official said.

Kerry also plans to speak by phone with Massoud Barzani, the head of the Kurdish Regional Government based in Irbil to encourage the Kurds not go ahead with unilateral actions - especially involving oil, like a pipeline deal with Turkey. He will not meet with Iraqi Foreign Minister Hoshyar Zebari because he is in Doha for an Arab League meeting

He will stress the "importance of maintaining the unity of Iraq," say that "separate efforts undercut the unity of the country" and that "The Kurdish republic cannot survive financially without the support of Baghdad," the official said.

Kerry's visit if the first by a U.S. secretary of state since Clinton went in 2009. During Obama's first term, the Iraq portfolio was largely delegated to Vice President Joe Biden.

Mom, 2 sons improving after Ala. airport sign fell

MONTGOMERY, Ala. (AP) ? A woman and two of her sons were improving Sunday after being seriously injured when a flight information billboard fell on them at an airport.

A third son was killed Friday when the electronic board, weighing at least 300 pounds, fell from a wall at the Birmingham-Shuttlesworth International Airport.

The boys' mother, Heather Bresette, had broken ankles and a crushed pelvis. She had surgeries over the weekend, but she was still in intensive care and unconscious, University Hospital spokeswoman Nicole Wyatt said.

"She does not know that her baby is dead," the family's priest, the Rev. Don Farnan, said.

The Bresettes, a family of seven, took a weeklong vacation to Destin, Fla., and were about to fly home to Overland Park, Kan., when the arrival-departure sign fell.

Luke Bresette, 10, was killed. His brother, 5-year-old Tyler, suffered a concussion. His 8-year-old brother, Sam, had a broken leg and nose. Tyler was let out of a children's hospital Sunday.

Luke was the middle child of the five. The father, Ryan Bresette, and another son and daughter, were at the airport but not injured.

During their vacation, the family swam in the Gulf of Mexico and Luke went parasailing for the first time.

"His dad said he was thrilled. He was an adventurous kid. He loved sports," said Farnan, a priest at St. Thomas More in Kansas City, Mo.

After the sign fell, it took six people to lift the large board and a dozen people to hold it up while first responders administered aid. Officials were investigating how the sign fell at the newly renovated airport and took down an identical billboard on Saturday.

The renovated concourse opened March 13. It was part of an ongoing $200 million upgrade of Birmingham's airport. The construction began in June 2011 and is being overseen by Brasfield & Gorrie Global Services Group.

The Birmingham-based company said in a statement it was working with airport authorities to determine why the sign fell.

"This is a terrible tragedy that none of us fully understand, and we hope that the family who lost their loved one will find strength through prayer and the support of all of us," the statement said.

At St. Thomas More, hundreds of worshippers showed up for a Saturday morning Mass that usually has about 75 people. Luke's uncle Alex Bresette placed a Rockhurst High School jersey on the altar.

"He would have been in the Class of 2020," he told the Kansas City Star.

Ryan Bresette said in a message on Facebook that words cannot describe the pain the family feels.

In a note to his son, he wrote, "I miss and love Luke so very much. I love you Luke!"

"Ryan is especially grateful for the amazing support of the people in Birmingham. They even started a fund for the family at a bank there," Farnan said. "There are long, loving arms that stretch between Birmingham and Kansas City."

Investigation launched into death of Putin foe Berezovsky

By Guy Faulconbridge and Maria Golovnina

LONDON (Reuters) - Boris Berezovsky, the Russian oligarch who helped broker Vladimir Putin's rise to the Kremlin's top job only to become his sworn enemy, has been found dead at his home in Britain in unclear circumstances. He was 67.

Police in Britain, where the tycoon fled in 2000 after falling foul of the Kremlin under Putin, said on Saturday the death was unexplained and they had started an investigation.

Associates said the man who personified the ruthless world of post-Soviet politics may have committed suicide or suffered a heart attack following the stress of losing a $6 billion court case to Chelsea Football Club owner Roman Abramovich.

He was found at his house in Ascot, a commuter town 25 miles west of London, by one of his bodyguards, possibly in his Russian sauna.

"I can confirm he died in his home. I've known him for a long, long time, we have spent a lot of time together," Andrei Sidelnikov, a Russian dissident living in London who was a friend of Berezovsky's, told Reuters.

"I am shocked. It is the end of an epoch."

A fast-talking former mathematician who scaled the heights of the ruthless world of post-Soviet business and politics, Berezovsky clashed with Putin soon after his election in 2000 and fled for Britain where he became his most vociferous enemy.

From his base in London, Berezovsky vowed to overthrow Putin whom he cast as a corrupt 'bandit' surrounded by venal ex-KGB spies. Once a supporter, he accused Putin of rolling back the freedoms won after the 1991 collapse of the Soviet Union.

Berezovsky's court included some of Putin's most wanted enemies, including a former Chechen rebel, and the former billionaire funded opposition leaders and former spies such as Alexander Litvinenko, who was murdered in London in 2006.

Putin fumed at any mention of Berezovsky and his asylum in Britain strained ties between London and Moscow, which cast Berezovsky as a criminal who should stand trial for massive fraud and tax evasion.

"UNRELIABLE WITNESS"

Once cast as the 'godfather of the Kremlin' by foes and admirers alike, Berezovsky was humiliated in 2012 when he lost a legal battle with former partner Abramovich, over shares in Russia's fourth biggest oil company.

The judge, Elizabeth Gloster, said Berezovsky was an "unimpressive and inherently unreliable witness" who would say "almost anything to support his case".

Some associates said that Berezovsky, once one of Russia's richest billionaires, had grappled with the financial impact of losing the case, which lawyers at the time said could open him up to claims for costs of considerably more than $100 million.

Clearly shaken by the verdict in August, Berezovsky said it appeared to have been written by Putin himself but in the months following he kept a low profile and was rarely seen in public.

Berezovsky had sought as much as $6 billion from Abramovich whom he accused of using the threat of Kremlin retribution to intimidate him into selling out of Russia's fourth biggest oil company at a knockdown price. He also accused Abramovich of selling his shares in RUSAL, the world's top aluminum producer, without his permission.

The judge dismissed all of Berezovsky's claims.

In an effort to recoup some of the losses incurred during case, Berezovsky is said to have auctioned off an Andy Warhol portrait of Soviet leader Vladimir Lenin to raise cash.

He agreed to pay one of Britain's biggest-ever divorce settlements to his former wife Galina in 2011. Local media said the settlement was believed to be more than $100 million.

"My sources say it was heart failure," said Alexei Venediktov, editor of Russia's Ekho Moskvy radio. "After his recent loss in court against Roman Abramovich he was in deep depression, he was being treated, he was treated in Israel."

"I think it was probably his health, including depression, and his age. Boris Abramovich never took it easy - he was a fighter, he led an active lifestyle, and unfortunately he has left life in this way."

Known for his love of cognac, beautiful women and for his ability to talk well into the night, Berezovsky lived the adrenaline-fuelled life of Russia's A-team of oligarchs.

Whatever the circumstances of his final hours, his death marks the end of an era for many Russians for whom Berezovsky epitomized the oligarch of the 1990s: brash, arrogant and dangerous alpha males who made their own rules.

UNLIKELY OLIGARCH

As a mathematician working in an obscure section of the Academy of Sciences, Berezovsky was an unlikely oligarch.

But the collapse of the Soviet Union helped propel him from academia to the pinnacle of one of the most ruthless, corrupt and violent business environments on earth - post Soviet Russia.

As the Soviet empire crumbled and gang wars erupted in Moscow, Berezovsky forged a profitable relationship with AvtoVAZ, Russia's biggest carmaker and producer of the Lada.

With the rouble worth nothing, cars were a tradeable asset, though to protect his fortune, Berezovsky forged ties with the Chechen gangs - some of the most feared in Russia.

The graveyards of Russia attest to the short lifespans of many businessmen in the 1990s and Berezovsky came close: in 1993 he faced a gun battle in central Moscow and a year later the Mercedes he was in was blown up, decapitating his driver.

But with nerves of iron and flush with cash, Berezovsky went for gold: he paid for the publication of President Boris Yeltsin's memoirs, securing him the goodwill of Russia's leader.

His political clout gave him access to Aeroflot, once the Soviet flag carrier, and then to oil.

After meeting on a Caribbean yacht trip organized by fellow tycoon Pyotr Aven, Berezovsky and Abramovich, then a 28-year-old oil trader, came up with a simple idea: merge Russia's best refinery with some of the top oil and gas fields of Siberia.

The result was Sibneft over which they would clash years later in a London courtroom.

"Everything can be bought and everything on earth has a price," he once said. "Politicians are the hired help of entrepreneurs."

But if Kremlin politics under Yeltsin had helped Berezovsky to the top, Kremlin politics under Putin proved his downfall.

'GODFATHER OF THE KREMLIN'

Facing the prospect of a Communist victory in 1996, Berezovsky helped rally the billionaire barons of Siberia to Yeltsin's side. He won. And the oligarchs carved up more of Russia's vast oil and metals sector.

But as Yeltsin's health deteriorated in 1999 and his popularity plummeted, Berezovsky and others began to look for a protege who could rule Russia for its second post-Soviet decade.

The obscure and quiet former KGB spy they found was Putin and Berezovsky helped pitch him when the powerbrokers of Russia met at their country houses, known as dachas, outside Moscow.

"Boris Berezovsky was certainly the political father of Vladimir Putin. He was the person who found Putin," commentator Sergei Parkhomenko said on Ekho Moskvy radio.

While Putin was happy to receive support, he resented the meddling that Berezovsky and oil oligarch Mikhail Khodorkovsky felt was their right. Berezovsky could not win. His only option was to flee.

According to Russian journalist Ilya Zhegulev, who spoke to him on Friday, Berezovsky was pining for Russia.

"I should not have left Russia," she quoted him as saying. "He said: I don't know what to do. I am 67 and I don't know."

Putin's spokesman, Dmitry Peskov, told state-run Rossya-24 television that Berezovsky had written to Putin and asked for help in returning to Russia.

Berezovsky did not return.

Promoters: MMA fighter faked own death, ruse discovered after arrest for armed robbery

We're not experts on faking our own death, but it would seem you might want to avoid getting arrested and charged with armed robbery and assault with intent to murder less than a month after pulling off your ruse.

That challenge, however, was apparently too much for Charles Rowan. The 25-year-old MMA fighter from Michigan was recently hauled in by police after they alleged he robbed a store named "Guns and Stuff" with his girlfriend Rosalinda Martinez and friend Michael Bowman.

Seeing Rowan's mug shot on the news came as a surprise to his promoters Christo Piliafas and Scott DiPonio. Both say they had been told by Martinez and Bowman in late February that the amateur heavyweight had died in a car accident and that they had helped raise over $1,000 for his funeral costs.

From the Associated Press:

Rowan's fifth career fight was scheduled for February in Traverse City. That night, DiPonio said, Martinez called from Rowan's phone number to tell him that her boyfriend had been involved in a fatal car wreck on the way to the event.

A distraught DiPonio and his girlfriend hopped in their car the next day and made the lengthy trek to Gladwin, where they were met by ''young kids and grandparents crying.''

''I thought for sure Charlie was dead. I mean, these people were hysterically crying,'' said DiPonio, who gave the family $150 for expenses on the spot.

Two weeks ago, Piliafas and DiPonio helped raise $1,350 in proceeds and donations through their benefit event, ''Fight for Charlie.''

Rowan had a career record of 1-3 and his rap sheet is equally as poor. He has past convictions for failing to register as a sex offender and delivery and manufacture of marijuana.

Ex-Oklahoma teacher gets 45-year sentence for child exploitation

By Steve Olafson

OKLAHOMA CITY (Reuters) - A former third-grade teacher in Oklahoma was sentenced to 45 years in prison on Friday for taking lewd photos of her young students at the behest of a retired college professor.

Kimberly Crain pleaded guilty to 19 counts of sexual exploitation of a child under 12, possessing child pornography and lewd molestation, according to District Attorney Richard Smothermon.

Crain blamed much of her actions on retired Pennsylvania college professor Gary Doby, whom she described as an "online love interest" who urged her to provide him photos of her students at the grade school in McLoud, a small town 30 miles east of Oklahoma City.

Doby, 66, who had met Crain in the 1970s when he taught at Oklahoma Baptist University, was sentenced to life in prison in January.

In a letter to the court, Crain also cited depression, menopause and an inattentive husband for her actions.

Crain, 50, will not be eligible for parole until she is 87 because she must serve 85 percent of her sentence, said Smothermon.

"This literally shook the community to its core," Smothermon said. "She was trusted and beloved by the community."

HBO's Richard Plepler Weighs In On Game Of Thrones Piracy, Says ?Maybe' On Broadband-Only HBO

richard pleplerWhen TechCrunch attended the San Francisco premiere of Game of Thrones Season 3, we didn't just ask the cast members about their smartphones. I also had a few minutes to talk to HBO CEO Richard Plepler, when I asked him about the show's status as the most-pirated program of 2012. "Well, look, it's the good news and the bad news, right?" Plepler said. "The good news is that a lot of people want to see it. Over 12.5 million people are watching it legally. And most of that pirating is occurring overseas. We're going to do what we can to bring that down, and we're going to do what we can, obviously, to bring that down in the United States as well."

Dell Latitude 10 review: a business-friendly Windows tablet with great battery life

We've been making the grand tour of Windows 8 hybrids running low-powered Atom processors, and our latest stop is Dell's Latitude 10. While some similar systems, such as the ASUS VivoTab Smart and the Lenovo ThinkPad Tablet 2, focus on portable designs and long battery life, the Latitude 10 takes after that group of devices with "Smart" and "Pro" in their name.

Indeed, like the Surface Pro and Samsung ATIV Smart PC Pro, the Latitude 10 flaunts a large variety of corporate-friendly features, such as TPM, a productivity dock, a Wacom-certified stylus and a Bluetooth keyboard. The entry-level configuration will set you back a tolerable $499, but adding on business essentials such as the dock and keyboard could soon have you looking at a price above the $1,000 threshold. Does the Latitude 10 work well enough to warrant the dough -- and satisfy on-the-go professionals? You know where to look if you want to find out.

Fossil bird study on extinction patterns could help today's conservation efforts

Mar. 21, 2013 ? A new University of Florida study of nearly 5,000 Haiti bird fossils shows contrary to a commonly held theory, human arrival 6,000 years ago didn't cause the island's birds to die simultaneously.

Although many birds perished or became displaced during a mass extinction event following the first arrival of humans to the Caribbean islands, fossil evidence shows some species were more resilient than others. The research provides range and dispersal patterns from A.D. 600 to 1600 that may be used to create conservation plans for tropical mountainous regions, some of the most threatened habitats worldwide. Understanding what caused recent extinctions -- whether direct habitat loss or introduction of invasive species -- helps researchers predict future ecological impacts. The study was published online in The Holocene March 12 and is scheduled to appear in the journal's print edition in July.

"People arrive about 6,000 years ago and within a millennium or two, you lose the big, spectacular critters -- the ground sloths, the monkeys, the biggest rodents and some of the big extinct birds, like giant owls and eagles," said lead author David Steadman, ornithology curator at the Florida Museum of Natural History on the UF campus. "We have some bird species from our fossil site that, from a modern standpoint, are just as extinct as the others, but in fact, they almost were able to survive longer. That helps give us a gauge on what the future might bring."

Researchers used comparisons with modern bones to identify 23 species from the 4,857 bird fossils excavated from Trouing Jean Paul, a cave in southeast Haiti at an elevation of about 6,000 feet. The most common bird species include the Zenaida Dove, the Black Swift, the Least Pauraque, the Hispaniolan woodpecker and a new, undescribed extinct woodcock in the genus Scolopax. Researchers believe the woodcock became extinct between A.D. 1350 and 1800, surviving the first arrival of the Amerindians 6,000 years ago, but dying off following the arrival of Europeans and African peoples in 1492, Steadman said.

"When you take a look at what could've caused this, it really does just keep pointing to humans," Steadman said. "I just think it's habitat loss from people and introduction of non-native, invasive plants and animals. It's the same thing we're dealing with in Florida now -- who knows what the pythons are going to wipe out in the Everglades."

Researchers radiocarbon-dated six individual bones from the extinct woodcock to determine the site's age. Because the locality also includes fossils of frogs, lizards, snakes, bats and rodents, in addition to the Common Barn Owl and Ashy-faced Owl, it was likely a roost where owls deposited boney pellets of their prey, scientists said.

Of the present-day species found at the site, as many as one-third are considered threatened today and four of the 23 total species are no longer found in the area. Their predominant habitat was pine forests, which are mostly disturbed today or entirely cut down for agriculture. The Least Pauraque, a type of nightjar, is now an endangered species that lives in an extremely localized area, Steadman said.

"This gives us some evidence of how drastic the range contraction was of this species -- the Least Pauraque not only lived in the mountains, it was common there," Steadman said. "Within 1,000 years, it's lost most of its range and most of its population. From the standpoint of evolution, if we want that species to ever have the opportunity to evolve through time, we need to be concerned with time intervals that are measured in centuries and millennia, not just decades."

Jim Mead, professor and chair of the department of geosciences at East Tennessee State University, said the research is important because the direct radiocarbon dating represents a much later time period than the arrival of the first Amerindians.

"What Steadman is finding, more often than not, is that we as people bring in other things with us and indirectly wipe out other animals," said Mead, who was not involved with the study. "He's providing background data and I think that's critical to Hispaniola because you have two countries on that island and they're quite different culturally and economically, so those countries are going to play different games on the local fauna."

Mead said it is also significant that Trouing Jean Paul occurs at a high elevation, where human or climate pressures could result in animals finding a "refugia" upslope.

"Typically, a lot of sites are found in lower elevation, or we go to the lower elevations to look at localities we work on," Mead said. "But Dave is saying, 'Why don't we look at these other areas that haven't really been examined?' This one cave is a critical one for that. It gives us a 3-D look at environments on an island."

Oona Takano, who helped sort and identify the specimens as a UF undergraduate student, is a study co-author.

72% of Professors Who Teach Online Courses Don't Think Their Students Deserve Credit

3475417696_9565941ee0_nThis is not a good sign for online education: 72 percent of professors who have taught Massive Open Online Courses (MOOCs) don't believe that students should get official college credit, even if they did well in the class. More importantly, these are the professors who voluntarily took time to teach online courses, which means the actual number of professors who discount the quality of MOOCs is probably much (much) higher. The survey reveals the Grand Canyon-size gap between the higher-education establishment and the coalition of tech companies and lawmakers that are mandating college credit for online courses.

South Korea: Chinese address source of attack

SEOUL, South Korea (AP) ? Investigators have traced a coordinated cyberattack that paralyzed tens of thousands of computers at six South Korean banks and media companies to a Chinese Internet Protocol address, authorities in Seoul said Thursday.

IP addresses, which are unique to each computer connected to the Internet, can easily be manipulated by hackers operating anywhere in the world, and the investigation into who was actually behind Wednesday's attack and whether they were in China could take weeks. Suspicion for the simultaneous shutdown is still focused on North Korea, which has threatened Seoul and Washington in recent days over U.N. sanctions imposed for its Feb. 12 nuclear test and is accused of waging similar cyberattacks over the past four years.

The cyberattack did not affect the government or military, and there were no immediate reports that customers' bank records were compromised. But it disabled scores of cash machines across the country, disrupting commerce in this tech-savvy, Internet-dependent country, and renewed questions about South Korea's Internet security and vulnerability to hackers.

If the attack was in fact carried out by North Korea, the purpose would seem to be to send a tacit message ? and a warning ? to South Korea that Pyongyang is capable of breaching its computer networks.

On Thursday, only one of the six targets, Shinhan Bank, was back online and operating regularly.

South Korean investigators say there is no proof yet that North Korea was behind the attack. However, the outage took place as Pyongyang warned Seoul against holding joint military drills with the U.S. that it considers rehearsals for an invasion.

North Korea also has threatened retaliation for sanctions imposed for the nuclear test, as well as its launch of long-range rocket in December. Pyongyang blames Seoul and Washington for leading the push to punish the North.

The Korean Peninsula has remained in a technical state of war, divided by a heavily militarized border, since the foes signed a truce in 1953. Over the past decade, the two Koreas have engaged in deadly naval skirmishes in waters that both countries claim. And increasingly, their warfare has extended into cyberspace.

Seoul's National Intelligence Services believes Pyongyang was behind six cyberattacks between 2009 and 2012.

Pyongyang, meanwhile, blamed Seoul and Washington for an Internet shutdown that disrupted its network last week.

"If it plays out that this was a state-sponsored attack, that's pretty bald-faced and definitely an escalation in the tensions between the two countries," said James Barnett, former chief of public safety and homeland security for the U.S. Federal Communications Commission.

An ominous question is which other businesses, in South Korea or elsewhere, may also be in the sights of the attacker, said Barnett, who heads the cybersecurity practice at Washington law firm Venable.

"This needs to be a wake-up call," he said. "This can happen anywhere."

Wednesday's attack in South Korea, which disabled some 32,000 computers at broadcasters YTN, MBC and KBS, as well as three banks, appeared to come from "a single organization," regulators said. The initial findings were based on results from an investigation into one target, Nonghyup Bank, and the investigation is continuing into the shutdown at the five other firms.

A malicious code that spread through the Nonghyup server was traced to an IP address in China, said Cho Kyeong-sik, a spokesman for the state-run Korea Communications Commission.

The attack may also have extended to the United States. The website of the U.S.-based Committee for Human Rights in North Korea also was hacked, with reports on satellite imagery of North Korean prison camps and policy recommendations to the U.S. government deleted from the site, according to executive director Greg Scarlatoiu.

However, experts say signs do not point to Chinese hackers since Chinese hacking, either from Beijing's cyber-warfare command or freelance hackers, tends to be aimed at collecting intelligence and intellectual property ? not simply at disrupting commerce.

China also is home to a sizable North Korean community, both North Koreans working in the neighboring nation and Chinese citizens of ethnic ancestry who consider North Korea their motherland.

In 2011, computer security software maker McAfee Inc. said North Korea or its sympathizers likely were responsible for a cyberattack against South Korean government and banking websites that year. The analysis also said North Korea appeared to be linked to a massive computer-based attack in 2009 that brought down U.S. government Internet sites. Pyongyang denied involvement.

Previous hacking attacks on commercial ventures have compromised the personal data of millions of customers. Past malware attacks also disabled access to government websites and destroyed files on personal computers.

Last year, North Korea threatened to attack several South Korean news outlets, including KBC and MBC, for reports critical of Pyongyang's activities.

In recent days, North Korea's Committee for the Peaceful Reunification of Korea ? a government agency that often targets South Koreans in its push to draw attention to reunification ? warned Seoul's "reptile media" that the North was prepared to conduct a "sophisticated strike" if its negative coverage continued.

"North Korea has almost certainly done similar attacks before," said Timothy Junio, a cybersecurity fellow at Stanford University's Center for International Security and Cooperation. "Part of why this wasn't more consequential is probably because South Korea took the first major incident seriously and deployed a bunch of organizational and technical innovations to reduce response time during future North Korea attacks."

South Korea also created a National Cybersecurity Center and Cyber Command modeled after the U.S. Cyber Command. Junio said South Korea's anti-virus firms also play a large role in stopping hacking attacks.

Immediately after Wednesday's attack, South Korean regulators distributed anti-virus software to government offices, banks, hospitals and other institutions. It could be days before the targeted companies are back online, and weeks before the investigation is complete.

"Hackers attack media companies usually because of a political desire to cause confusion in society," said Lim Jong-in, dean of Korea University's Graduate School of Information Security. "Political attacks on South Korea come from North Koreans."
