Officials: Boston suspects motived by religion

(AP) ? Two U.S. officials say preliminary evidence from an interrogation suggests the suspects in the Boston Marathon attack were motivated by their religious views but were apparently not tied to any Islamic terrorist groups.

The two brothers, from southern Russia, practiced Islam.

The U.S. officials spoke Monday on condition of anonymity because they were not authorized to publicly discuss the investigation.

One of the brothers died in a police shootout Friday. The other brother was formally charged Monday after being questioned by federal officials in his hospital room where he is recovering from multiple injuries.

China says new bird flu case found in northeast

BEIJING (Reuters) - A man in the northeastern Chinese province of Shandong has been infected by a new strain of bird flu, the first case found in the province, state news agency Xinhua said on Monday, bringing the total number of victims in China to 105.

The H7N9 virus has killed 20 people in China. Although it is not clear how people are becoming infected, the World Health Organization (WHO) says there is no evidence of the most worrying scenario - sustained transmission between people.

A 36-year-old man from the city of Zaozhuang in Shandong was being treated in hospital, while two more people were infected in eastern Zhejiang province, Xinhua said.

A total of nine people in close contact with the victim in Shandong were under observation but were showing no signs of infection, Xinhua said.

An international team of experts led by the WHO has carried out field investigations into the response to the virus in Shaghai, where many of the cases have occurred, said Keiji Fukuda, WHO's assistant director-general for health, security and the environment.

"Right now we are in the middle of our work. We have not come up with any final conclusions, and I think it is too early to say," Fukuda told reporters.

Other bird flu strains, such as H5N1, have been circulating for many years and can be transmitted from bird to bird and bird to human, but do not generally pass from human to human

But Ho Pak-leung, an associate professor in the Department of Microbiology at the University of Hong Kong, noted in the British Medical Journal (BMJ) that in the two months since it was first detected, the H7N9 flu has already resulted in almost twice as many confirmed infections in China as H5N1 caused there in a decade.

"H7N9 is much more transmissible to humans, and it's much more difficult to track down," he told the BMJ, adding: "We don't understand why it's so difficult to find."

He said he did not believe the difficulties were related to sampling techniques or testing levels, but thought it could be that virus can only be detected in infected animals for a few days, meaning the timing of tests could be important.

"It (also) might be that they are not sampling enough animal species, and they may have to take a look at the less common species of birds being sold in Chinese markets," he said.

The WHO's China representative, Michael O'Leary, issued data on Friday showing that half of the patients analyzed had no known contact with poultry, the most obvious potential source, but he said it appeared human-to-human transmission was rare.

Some bird samples have tested positive and China has culled thousands of birds and shut down some live poultry markets.

China rushes relief after Sichuan quake kills 179

YA'AN, China (AP) ? Rescuers and relief teams struggled to rush supplies into the rural hills of China's Sichuan province Sunday after an earthquake left at least 179 people dead and more than 6,700 injured and caused frightened survivors spent a night in cars, tents and makeshift shelters.

The earthquake Saturday morning triggered landslides that cut off roads and disrupted phone and power connections in mountainous Lushan county, further south on the same fault line where a devastating quake wreaked widespread damage across the region five years ago.

Hardest hit Saturday were villages further up the valleys, where farmers grow rice, vegetables and corn on terraced plots. Rescuers hiked into neighboring Baoxing county after its roads were cut off, reaching it overnight, state media reported. In Longmen village, authorities said nearly all the buildings had been destroyed in a frightening minute-long shaking by the quake.

In the fog-covered town of Shuangli, corn farmer Zheng Xianlan said Sunday that the quake damaged her house, in a setback for a family that does not have much money. She rushed from the fields back to her home when the quake struck, and cried when she saw that the roof collapsed. She then spent the night outdoors on a worn sofa using a plastic raincoat for a cover to watch over it.

"We don't earn much money. We don't know what we will do now," said 58-year-old Zheng, her eyes welling with tears. "The government only brought one tent for the whole village so far, but that's not enough for us."

Along the main roads, ambulances, fire engines and military trucks piled high with supplies waited in long lines, some turning back to try other routes when roads were impassable.

Rescuers were forced to dynamite boulders that had fallen across roads, and rains Saturday night slowed rescue work, state media reported.

Chinese Premier Li Keqiang arrived Saturday afternoon by helicopter in Ya'an to direct rescue efforts, the government's official Xinhua News Agency reported.

"The current priority is to save lives," Li said, after visiting hospitals, tents and climbing on a pile of rubble to view the devastation, according to Xinhua.

Xinhua, citing the China Earthquake Administration, said at least 179 people had died, and more than 6,700 were injured.

The quake ? measured by the earthquake administration at magnitude-7.0 and by the U.S. Geological Survey at 6.6 ? struck shortly after 8 a.m. Saturday, when many people were at home, sleeping or having breakfast.

Tens of thousands of people moved into tents or cars, unable to return home or too afraid to go back as aftershocks continued to jolt the region. In Ya'an, a city that administers Lushan, where aftershocks rattled buildings nearly a day after the quake, residents sat in groups outside convenience stores watching the news on television sets early Sunday. Fourteen-year-old Wang Xing sat with her family on chairs by the roadside in the cool night air, a large blanket on her lap.

Wang and her relatives decided to spend the night in their cars. "We don't feel safe sleeping at home tonight," said Wang, a student. She said the quake left tears on the walls of her family's house. "It was very scary when it happened. I ran out of my bed and out of the house. I didn't even have my shoes on."

As in most natural disasters, the government mobilized thousands of soldiers and others, sending excavators and other heavy machinery as well as tents, blankets and other emergency supplies. Two soldiers died after their vehicle slide off a road and rolled down a cliff, state media reported.

The Chinese Red Cross said it had deployed relief teams with supplies of food, water, medicine and rescue equipment to the disaster areas.

Lushan, where the quake struck, lies where the fertile Sichuan plain meets foothills that eventually rise to the Tibetan plateau and sits atop the Longmenshan fault. It was along the same fault line that a devastating magnitude-7.9 quake struck on May 12, 2008, leaving more than 90,000 people dead or missing and presumed dead in one of the worst natural disasters to strike China in recent decades.

"It was just like May 12," Liu Xi, a writer in Ya'an city, said via a private message on his account on the Twitter-like Weibo service. "All the home decorations fell at once, and the old house cracked."

The official Xinhua News Agency said the well-known Bifengxia panda preserve, which is near Lushan, was not affected by the quake. Dozens of pandas were moved to Bifengxia from another preserve, Wolong, after its habitat was wrecked by the 2008 quake.

Moderate earthquake strikes western Mexico, no major damage

MEXICO CITY (Reuters) - A magnitude 5.9 earthquake struck western Mexico on Sunday, shaking buildings in the capital, but there were no reports of significant damage or injuries, officials said.

The quake, initially reported as a magnitude 6.2 off the coast, was centered 33 km (20 miles) northwest of La Union, on the border between Guerrero and Michoacan states, close to the Pacific coast, the U.S. Geological Survey said.

State oil monopoly Pemex said shortly after the quake that the power supply to its Tula refinery was interrupted. Not long after, it reported electricity was coming back on line again.

Pemex said it was unclear if the tremor had caused the break in energy supply at the Tula refinery, Mexico's second biggest. It has a production capacity of 315,000 barrels per day.

A Pemex official could not say whether production had been affected, but added that any loss would be made up.

The quake was felt in Mexico City, about 325 km (200 miles) away from La Union. Buildings shook and residents briefly ran outdoors, but most returned inside shortly afterwards.

Several senior Mexican officials, including Interior Minister Miguel Angel Osorio Chong, said via Twitter there were no immediate reports of injuries or significant damage.

First 2000-year-long temperature reconstructions for individual continents

Apr. 19, 2013 ? Past climate change varied remarkably between regions. This is demonstrated in a new study coordinated by the international Past Global Changes (PAGES) project, which reconstructed temperature over the past 1000 to 2000 years.

It is the first comprehensive temperature reconstruction on a continental scale. One of its main findings is that a general cooling trend, caused by different factors (e.g. orbital-driven insolation and changes in solar and volcanic activity), was ubiquitous across all continental-scale regions and was reversed by a distinct warm trend beginning at the end of the 19th century.

The scale of this project is impressive. Some 80 researchers from all over the world collaborated on the study, which has just been published in the scientific journal Nature Geoscience. In one of the widest-ranging efforts yet undertaken to reconstruct climate across the globe, the international author team evaluated data from all continents to track the evolution of temperatures over the past one to two millennia.

This major project was initiated and coordinated by the Past Global Changes (PAGES) organization. PAGES was established in 1991 to facilitate international research into understanding climatic and environmental dynamics by studying the past. The program receives funding mainly from the Swiss and US national science foundations. In 2006, ambitious scientists in the PAGES network decided to organize an initiative to reconstruct the climate of the last 2000 years in unprecedented quality.

The first results of the collective effort have now been published. "A key aspect of the consortium effort was to engage regional experts who are intimately familiar with the evidence for past climate changes within their regions," says Heinz Wanner, emeritus professor at the University of Bern and one of the original architects of the PAGES 2k Network.

"Several mathematical procedures were applied to reconstruct the continental temperature time series and they were compared to assess the extent to which the main conclusions of the study stood up to the different analytical approaches." Previous attempts to reconstruct temperature changes focused on hemispheric or global-scale averages, which are important, but overlook the pronounced regional-scale differences that occur along with global changes, he points out.

Natural climate archives and documentary sources

For the present study, "Continental-scale temperature variability during the last two millennia," the researchers drew up temperature curves for large regions at seven continents, using 511 local temperature records. These were based on the analysis of tree rings, pollen, corals, lake and marine sediments, ice cores and stalagmites as well as historical documents.

In most cases the data used were highly resolved, attesting to short-term variations over decades or less, rather than smoothing over centuries. In Africa, there were too few records to accurately determine long-term temperature changes for that continent. Nevertheless, the expansive new dataset will undoubtedly be used in future studies, including for comparisons with the output of climate models used to help project future climate change.

The evolution of temperature across all the continents was noticeably more similar within the hemispheres than between the Northern and Southern Hemisphere. "Distinctive periods, such as the Medieval Warm Period or the Little Ice Age stand out, but do not show a globally uniform pattern," says professor Heinz Wanner.

By around 1500 AD temperatures did indeed fall below the long-term mean everywhere. However, in the Arctic, Europe and Asia this temperature drop occurred several decades earlier than in North America and the Southern Hemisphere. These new findings will certainly stimulate vibrant discussions within the research community, Wanner believes.

Long-term cooling trend reversed

The most consistent feature across the regions over the last 2000 years was a long-term cooling trend, which was likely caused by a combination of factors such as an overall increase in volcanic activity, a decrease in solar irradiance, changes in land cover, and slow changes in earth's orbit. This cooling only came to an end toward the end of the 19th century.

The warming during the last century has reversed this long-term cooling, the study found. It remained cold only in Antarctica. An analysis of the average temperatures over 30-year periods indicates that interval from 1971-2000 was probably warmer than any other 30-year period in the last 1400 years.

Cooler 30-year periods between the years 830 and 1910 AD were particularly pronounced during weak solar activity and strong tropical volcanic eruptions. Both phenomena often occurred simultaneously and led to a drop in the average temperature during five distinct 30- to 90-year intervals between 1251 and 1820.

Warming in the 20th century was on average twice as large in the northern continents as it was in the Southern Hemisphere. During the past 2000 years, some regions experienced warmer 30-year intervals than during the late 20th century. For example, in Europe the years between 21 and 80 AD were possibly warmer than the period 1971-2000.
