Are Honeybees Losing Their Way?

A single honeybee visits hundreds, sometimes thousands, of flowers a day in search of nectar and pollen. Then it must find its way back to the hive, navigating distances up to five miles (eight kilometers), and perform a "waggle dance" to tell the other bees where the flowers are.

A new study shows that long-term exposure to a combination of certain pesticides might impair the bee's ability to carry out its pollen mission.

"Any impairment in their ability to do this could have a strong effect on their survival," said Geraldine Wright, a neuroscientist at Newcastle University in England and co-author of a new study posted online February 7, 2013, in the Journal of Experimental Biology.

Wright's study adds to the growing body of research that shows that the honeybee's ability to thrive is being threatened. Scientists are still researching how pesticides may be contributing to colony collapse disorder (CCD), a rapid die-off seen in millions of honeybees throughout the world since 2006.

"Pesticides are very likely to be involved in CCD and also in the loss of other types of pollinators," Wright said. (See the diversity of pollinating creatures in a photo gallery from National Geographic magazine.)

Bees depend on what's called "scent memory" to find flowers teeming with nectar and pollen. Their ability to rapidly learn, remember, and communicate with each other has made them highly efficient foragers, using the waggle dance to educate others about the site of the food source.

Watch as National Geographic explains the waggle dance.

Their pollination of plants is responsible for the existence of nearly a third of the food we eat and has a similar impact on wildlife food supplies.

Previous studies have shown certain types of pesticides affect a bee's learning and memory. Wright's team wanted to investigate if the combination of different pesticides had an even greater effect on the learning and memory of honeybees.

"Honeybees learn to associate floral colors and scents with the quality of food rewards," Wright explained. "The pesticides affect the neurons involved in these behaviors. These [affected] bees are likely to have difficulty communicating with other members of the colony."

The experiment used a classic procedure with a daunting name: olfactory conditioning of the proboscis extension reflex. In layman's terms, the bee sticks out its tongue in response to odor and food rewards.

For the experiment, bees were collected from the colony entrance, placed in glass vials, and then transferred into plastic sandwich boxes. For three days the bees were fed a sucrose solution laced with sublethal doses of pesticides. The team measured short-term and long-term memory at 10-minute and 24-hour intervals respectively. (Watch of a video of a similar type of bee experiment.)

This study is the first to show that when pesticides are combined, the impact on bees is far worse than exposure to just one pesticide. "This is particularly important because one of the pesticides we used, coumaphos, is a 'medicine' used to treat Varroa mites [pests that have been implicated in CCD] in honeybee colonies throughout the world," Wright said.

The pesticide, in addition to killing the mites, might also be making honeybees more vulnerable to poisoning and effects from other pesticides.

Stephen Buchmann of the Pollinator Partnership, who was not part of Wright's study, underscored how critical pollinators are for the world. "The main threat to pollinators is habitat destruction and alteration. We're rapidly losing pollinator habitats, natural areas, and food—producing agricultural lands that are essential for our survival and well being. Along with habitat destruction, insecticides weaken pollinators and other beneficial insects."

Dorner Not IDed, But Manhunt Considered Over

Though they have not yet identified burned remains found at the scene of Tuesday's fiery, armed standoff, San Bernardino, Calif., officials consider the manhunt over for Christopher Dorner, the fugitive ex-cop accused of going on a killing spree.

"The events that occurred yesterday in the Big Bear area brought to close an extensive manhunt," San Bernardino County Sheriff John McMahon told reporters this evening.

"I cannot absolutely, positively confirm it was him," he added.

However, he noted the physical description of the suspect authorities pursued to a cabin at the standoff scene, as well as the suspect's behavior during the chase and standoff, matched Dorner, 33.

The charred remains of the body believed to be Dorner were removed from the cabin high in the San Bernardino Mountains near Big Bear, Calif., the apparent site of Dorner's last stand. Cornered inside the mountain cabin Tuesday, the suspect shot at cops, killing one deputy and wounding another, before the building was consumed by flames.

"We did not intentionally burn down that cabin to get Mr. Dorner out," McMahon said tonight, though he noted pyrotechnic canisters known as "burners" were fired into the cabin during a tear gas assault in an effort to flush out Dorner. The canisters generate high temperatures, he added.

The deputies wounded in the firefight were airlifted to a nearby hospital, where one died, police said.

The deceased deputy was identified tonight as Det. Jeremiah MacKay, 35, a 15-year veteran and the father of two children -- a daughter, 7, and son, 4 months old.

"Our department is grieving from this event," McMahon said. "It is a terrible deal for all of us."

The Associated Press quoted MacKay on the Dorner dragnet Tuesday, noting that he had been on patrol since 5 a.m. Saturday.

"This one you just never know if the guy's going to pop out, or where he's going to pop out," MacKay said. "We're hoping this comes to a close without more casualties. The best thing would be for him to give up."

The wounded deputy, identified as Alex Collins, was undergoing multiple surgeries for his wounds at a hospital, McMahon said, but was expected to make a full recovery.

Before the final standoff, Dorner was apparently holed up in a snow-covered cabin in the California mountains just steps from where police had set up a command post and held press conferences during a five-day manhunt.

The manhunt for Dorner, one of the biggest in recent memory, led police to follow clues across the West and into Mexico, but it ended just miles from where Dorner's trail went cold last week.

Residents of the area were relieved today that after a week of heightened police presence and fear that Dorner was likely dead.

"I'm glad no one else can get hurt and they caught him. I'm happy they caught the bad guy," said Ashley King, a waitress in the nearby town of Angelus Oaks, Calif.

Hundreds of cops scoured the mountains near Big Bear, a resort area in Southern California, since last Thursday using bloodhounds and thermal-imaging technology mounted to helicopters, in the search for Dorner. The former police officer and Navy marksman was suspected to be the person who killed a cop and cop's daughter and issued a "manifesto" declaring he was bent on revenge and pledging to kill dozens of LAPD cops and their family members.

But it now appears that Dorner never left the area, and may have hid out in an unoccupied cabin just steps from where cops had set up a command center.

Obama keeps faith in science and warns of cyber threats

Peter Aldhous, San Francisco bureau chief

"IT IS our unfinished task to restore the basic bargain that built this country - the idea that if you work hard and meet your responsibilities, you can get ahead."

In adopting the phrase "unfinished task" as a signature motif for his 2013 State of the Union address, President Barack Obama signalled a return to familiar themes. For those who care about investment in science, that was a reassuring message. 

The fight against global warming and the importance of technology to protect national security also got high billing. On the latter, Obama signaled that hacking skills, rather than kilotons, are increasingly a crucial currency, promising a new focus on combating cyberattacks - paralleled by negotiated cuts to the US nuclear arsenal. 

In a combative speech designed to counter Republican opponents who want to cut the budget deficit by curbing spending on Obama's priorities - including education and research - the President made the case for continued investment in innovation.

"Every dollar we invested to map the human genome returned $140 to our economy. Today, our scientists are mapping the human brain to unlock the answers to Alzheimer's; developing drugs to regenerate damaged organs; devising new material to make batteries ten times more powerful. Now is not the time to gut these job-creating investments in science and innovation. Now is the time to reach a level of research and development not seen since the height of the Space Race."

The estimate of a 140:1 return on investment in genomics comes from a 2011 study by the Battelle Memorial Institute in Columbus, Ohio. While the precise numbers from that analysis have been questioned, the importance of continued innovation to America's future economic competitiveness has been stressed in multiple reports, notably from the US National Academies. 

"Now our enemies are also seeking the ability to sabotage our power grid, our financial institutions, and our air traffic control systems. We cannot look back years from now and wonder why we did nothing in the face of real threats to our security and our economy."

Obama called on Congress to pass new legislation to counter threats from hackers backed by hostile governments. That won't be easy: last year, a bill that would have demanded that companies meet minimum standards for cybersecurity, and report if they are attacked, foundered amid complaints that it would impose large costs on US businesses.

Pope makes first appearance since shock resignation

VATICAN CITY: Pope Benedict XVI made his first public appearance Wednesday since the shock announcement of his resignation, sticking with his schedule by presiding over his weekly general audience.

Tickets to the event in the Vatican's Paul VI auditorium were issued well in advance, so several thousand pilgrims experienced the historic moment out of sheer luck just two days after the 85-year-old Benedict said he would step down at the end of the month.

The pope will then celebrate Ash Wednesday mass at 1600 GMT, his last public mass and one of his final engagements as pontiff.

The mass is traditionally held in the Santa Sabina Church on Rome's Aventine Hill, but has been moved to St Peter's Basilica out of respect for the outgoing pontiff and to accommodate the crowd of faithful who will want to mark the end of his eight-year rule -- one of the shortest in the Church's modern history.

"It will be an important concelebration, and the last led by the Holy Father in Saint Peter's," Vatican spokesman Federico Lombardi said.

The high point of Wednesday's mass, which launches the traditional period of penitence ahead of Easter in the Christian calendar, will see the pope mark the foreheads of the faithful with ashes.

Lombardi has said he expects a new pope in place in time for Easter, which falls on March 31 this year, although no date has yet been set for the secret conclave to elect a new leader of the world's 1.2 billion Catholics.

In the meantime, the outgoing pontiff will honour his existing engagements.

On Thursday he will hold his annual meeting with the pastors of Rome. And before he steps down at the end of the month he will also meet the presidents of Guatemala and Romania, as scheduled.

Next week will be given over to a spiritual retreat at the Vatican which is sure to be dominated by jockeying among factions within the College of Cardinals over the choice of Benedict's successor.

Benedict's decision to step down -- making him the first pontiff in 700 years to resign simply because he cannot carry on -- sparked a flurry of rumours over his health, fed by revelations that he had had an operation to replace the batteries in his pacemaker three months ago.

Some observers saw Benedict's decision as a bid to avoid the fate of his predecessor John Paul II, whose drawn-out and debilitating illness was played out on the world's stage.

But Lombardi insisted: "The pope is well and his soul is serene.

"He did not resign the pontificate because he is ill but because of the fragility that comes with old age."

After Ash Wednesday Benedict will, on the next two Sundays, will recite the Angelus from his apartment window and hold his final general audience, this time in St. Peter's Square on February 27, before retiring to a little-known monastery within Vatican walls.

Soon a new pope will be installed in the papal apartments, with his predecessor just a stone's throw away.

But Benedict will spend his time in prayer rather than giving advice, the Vatican says.

As rumours fly over front-runners for St. Peter's chair, commentators have said age may be a key factor in selecting a new pope, although any of the 117 cardinals eligible to vote is likely to be chosen.

While some hope Africa or Asia could yield the next pontiff, others have tipped high-flying European or North American cardinals. The new pope will have to face up to the growing secularism in the West, one of the Church's biggest challenges.

Only one other pope has resigned because of an inability to carry on -- Celestine V in 1294 -- a humble hermit who stepped down after just a few months saying he could no longer bear the intrigue of Rome.

Opera embraces WebKit in browser brain transplant

Opera CTO Håkon Wium Lie

(Credit:
Stephen Shankland/CNET)

Opera Software, an independent voice in the browser market since the 1990s, will dramatically change its strategy by instead adopting the WebKit browser engine used by Safari and Chrome.

The Norwegian company announced the move today and said it will show off the first fruits of the work with a WebKit-based version of its
Android browser at the Mobile World Congress show in less than two weeks. But the company will move to WebKit for its desktop browser, too.

A browser engine processes the Web page instructions written in HTML, JavaScript, and CSS then renders the results on screens. The engine also interactions that are increasingly important as the developer world expands from static Web pages to dynamic Web apps.

Opera Chief Technology Officer Håkon Wium Lie described the company's motives in a statement:

The WebKit engine is already very good, and we aim to take part in making it even better. It supports the standards we care about, and it has the performance we need. It makes more sense to have our experts working with the open source communities to further improve WebKit and Chromium, rather than developing our own rendering engine further. Opera will contribute to the WebKit and Chromium projects, and we have already submitted our first set of patches: to improve multi-column layout.

Hints of Opera's WebKit work emerged with a mobile-browser project called ICE in January, but today's news is a much more sweeping change than just a single product. Opera said it will move gradually to the WebKit for "most of its upcoming versions of browsers for smartphones and computers." It's not immediately clear which products will continue to use Opera's in-house technology, and Opera declined to say which.

Opera has struggled to keep its fifth-place ranking in the browser usage, but it's certainly not irrelevant. The company also announced today that 300 million people use its browsers each month.

But there are difficult trends the company must face. On mobile devices, Opera Mini is a strong contender, but its popularity is chiefly on lower-end phones; iOS and Android devices come with their own WebKit-based browsers. On personal computers, Google's Chrome rose from nowhere in a few years, quickly surpassing Opera and
Safari, while Microsoft by some measures has reversed declines in its share of browser usage.

Although ditching its in-house Presto browser engine raises the possibility of engineering layoffs, Opera spokeswoman Zara Lauder took an optimistic tone when asked about it.

"We have never had more people at Opera working on our products than right now, and we look forward to contributing to WebKit," Lauder said. "This change has been some time in the making, and all hands are now hard at work on making the best possible browser for our users."

Although Opera's profile is lower than that of many rivals, it's still functioning financially. During the company's third quarter of 2012, the most recent for which financial results are available, Opera reported revenue grew 40 percent to $56 million, and its profit was $6.5 million. Its revenue sources include payments from search traffic it drives to partners including Google and Yandex, its own advertising technology, and partnerships with mobile network operators.

The WebKit project began as the KHTML engine used in the KDE project to supply Linux with a polished user interface and a host of software utilities, but Apple became its chief sponsor when it based OS X's WebKit on the project. WebKit got another major boost with Google's embrace.

Adobe Systems now is also contributing as it moves to recreate many of Flash Player's abilities without requiring the browser plug-in, and WebKit also is used in the browsers of BlackBerry OS and Samsung's Bada.

One notable consequence of moving to WebKit is that Opera will be able to more easily support the large and growing number of iOS devices. Apple rules prohibit browser engines besides a version of WebKit that Apple itself supplies (and incidentally, that runs slower than the version Safari on iOS itself uses). Google's Chrome for iOS uses this Apple-supplied version of WebKit, and Opera would be able to make such a move more easily if its own browser used WebKit, too.

WebKit is not a single, unified project, though. For example, Chrome and Safari differ dramatically under the covers in how they execute the JavaScript programs on Web pages. Chrome uses Google's V8 JavaScript engine, whereas Safari uses a different one called Nitro. Opera said it will use V8.

Another consequence of Opera's change is that developers could have an easier time supporting browsers. Although independent testing will still be required, Web pages likely will be easier to write and test -- especially advanced ones using newer features such as animations and "responsive" design that can handle a wide variety of screen types.

With Opera throwing in the towel on its own Presto engine technology, the bulk of the browser market will be reduced to using three primary engines: WebKit, Microsoft's Trident, and Mozilla's Gecko.

Lie also announced Opera's move on the WebKit mailing list.

"Switching from Presto to WebKit frees up resources and allows us to contribute to the WebKit platform," Lie said.

Being part of WebKit potentially gives Opera more clout in the standards world, because it can build experiments that are more easily tested and adopted by fellow WebKit members. That, in turn, makes it easier to formalize new ideas into actual standards.

Opera has begun work on first such standard through WebKit, an approach at Web page layouts that handle multiple columns of text and graphics more easily. Opera has begun submitting patches for the multicolumn layout idea.

"We have experimented with combining multicol layout with page floats and column spans; in 10 lines of CSS code one can create amazingly beautiful, scalable, and responsive paged
presentations," Lie said.

Opera's move from Presto to WebKit arguably give the company a lot more engineering breathing room, since it can share labor with other browser makers instead of pulling all its own weight. But not everybody was happy to hear the news.

"Sad day for my former team at Opera and for the Web to lose a rendering engine," tweeted Anne van Kesteren, who for years worked on standards issues at Opera.

Obama Pledges U.S. Action on Climate, With or Without Congress

If there were anything in President Barack Obama's State of the Union to give hope to wistful environmentalists, it was the unprecedented promise to confront climate change with or without Congress, and to pursue new energy technology in the process.

Following his strong statements in his inaugural address about the ripeness of the moment to address a changing climate, Obama outlined a series of proposals to do it. Recognizing that the 12 hottest years on record all occurred in the last decade and a half, Obama said his most ambitious goal would be a "bipartisan, market-based solution," similar to the cap-and-trade system that died in Congress during his first term.(See related story: "California Tackles Climate Change, But Will Others Follow?")

But without legislative action, Obama threatened to act himself using executive authority. "I will direct my Cabinet to come up with executive actions we can take, now and in the future, to reduce pollution, prepare our communities for the consequences of climate change, and speed the transition to more sustainable sources of energy," he said. That will translate, White House officials said earlier in the week, to new regulations for existing coal-burning power plants and directives to promote energy efficiency and new technology research. (See related story: "How Bold a Path on Climate Change in Obama's State of the Union?")

The effort isn't one that can be stalled, he noted. Not just because of a warming planet, but also because of international competition from countries like China and parts of Western Europe that have gone "all in" on clean energy.

Energy experts signaled support of Obama's comments on energy security, including a plan for an Energy Security Trust to use revenue from oil and gas production on public lands to fund new energy research. "Clean energy businesses commend the president for reaffirming his commitment to reduce greenhouse gas emissions and to address the damaging and costly impacts of climate change," Lisa Jacobson, president of Business Council for Sustainable Energy, said in a statement. The influential League of Conservation Voters perked up to Obama's vow to act on climate change, even if alone.

Noticeably unmentioned in the speech was the Keystone XL pipeline that would carry oil from Canadian tar sands to the refining centers of Texas. Environmentalists have urged Obama to reject the project's application for federal approval in order to hold the line against carbon-intensive production from the oil sands. (See related blog post: "Obama and Keystone XL: The Moment of Truth?") Energy analysts believe Obama is likely to approve the project in the coming weeks, yet at the same time offer new regulations on domestic oil and natural gas development.

Other environmental analysts took Obama's remarks as simple talk, so far not backed by action. “How many times do we have to have the problem described?” David Yarnold, president of the Audubon Society said after the speech. “Smarter standards for coal-fired power plants are the quickest path to a cleaner future, and the president can make that happen right now.”

Obama's path toward accomplishing those goals will likely be lonely. In the Republican rebuttal to Obama's speech, Florida Senator Marco Rubio sidelined climate change as an issue of concern and highlighted the deep partisan distrust. "When we point out that no matter how many job-killing laws we pass, our government can’t control the weather, he accuses us of wanting dirty water and dirty air," Rubio said. He echoed the long-held Republican concern that remaking an economy may not be the wisest way to confront the problem of extreme weather.

Central to Obama's efforts will be his nominees to lead the Environmental Protection Agency and the Department of Energy in his second term. Both roles were at times attacked over his first term, notably when EPA instituted new air and water regulations and DOE was caught making a bad investment in the now-defunct solar manufacturer Solyndra. If the tone of his State of the Union offers a blueprint, he'll choose people unafraid to act.

Charred Human Remains Found in Burned Cabin

Investigators have located charred human remains in the burned out cabin where they believe suspected cop killer and ex-LAPD officer Christopher Dorner was holed up as the structure burned to the ground, police said.

The human remains were found within the debris of the burned cabin and identification will be attempted through forensic means, the San Bernardino County Sheriff-Coroner Department said in a press release early this morning.

Dorner barricaded himself in the cabin in the San Bernardino Mountains near Big Bear Tuesday afternoon after engaging in a gunfight with police, killing one officer and injuring another, the San Bernardino County Sheriff's Department said.

Cindy Bachman, spokeswoman for the San Bernardino County Sheriff's Department, which is the lead agency in the action, said Tuesday night investigators would remain at the site all night.

FULL COVERAGE: Christopher Dorner Manhunt

When Bachman was asked if police thought Dorner was in still in the burning cabin, she said, "Right… We believe that the person that barricaded himself inside the cabin engaged in gunfire with our deputies and other law enforcement officers is still inside there, even though the building burned."

Bachman spoke shortly after the Los Angeles Police Department denied earlier reports that a body was found in the cabin, contradicting what law enforcement sources told ABC News and other news organizations.

Fugitive Ex-Cop Believed Barricaded in Cabin, California Cops Say Watch Video

Police around the cabin told ABC News they saw Dorner enter but never leave the building as it was consumed by flames, creating a billowing column of black smoke seen for miles.

A press conference is scheduled for later today in San Bernardino.

One sheriff's deputy was killed in a shootout with Dorner earlier Tuesday afternoon, believed to be his fourth and victim after killing an LAPD officer and two other people this month, including the daughter of a former police captain, and promising to kill many more in an online manifesto.

PHOTOS: Former LAPD Officer Suspected in Shootings

Cops said they heard a single gunshot go off from inside the cabin just as they began to see smoke and fire. Later they heard the sound of more gunshots, the sound of ammunition being ignited by the heat of the blaze, law enforcement officials said.

Police did not enter the building, but exchanged fire with Dorner and shot tear gas into the building.

One of the largest dragnets in recent history, which led police to follow clues across the West and into Mexico, apparently ended just miles from where Dorner's trail went cold last week.

Police got a break at 12:20 p.m. PT, when they received a 911 call that a suspect resembling Dorner had broken into a home in the Big Bear area, taken two hostages and stolen a car.

The two hostages, who were tied up by Dorner but later escaped, were evaluated by paramedics and were determined to be uninjured.

Officials say Dorner crashed the stolen vehicle and fled on foot to the cabin where he barricaded himself and exchanged fire with deputies from the San Bernardino Sheriff's Office and state Fish and Game officers.

Two deputies were wounded in the firefight and airlifted to a nearby hospital, where one died, police said. The second deputy was in surgery and was expected to survive, police said.

Police sealed all the roads into the area, preventing cars from entering the area and searching all of those on the way out. Are schools were briefly placed on lockdown.

Arctic sunshine cranks up threat from greenhouse gases

IT'S a solar double whammy. Not only does sunlight melt Arctic ice, but it also speeds up the conversion of frozen organic matter into carbon dioxide.

The amount of carbon in dead vegetation preserved in the far northern permafrost is estimated to be twice what the atmosphere holds as CO₂. Global warming could allow this plant matter to decompose, releasing either CO₂ or methane – both greenhouse gases. The extent of the risk remains uncertain because the release mechanisms are not clear.

Rose Cory at the University of North Carolina at Chapel Hill and her colleagues analysed water from ponds forming on melting permafrost at 27 sites across the Arctic. They found that the amount of CO₂ released was 40 per cent higher when the water was exposed to ultraviolet light than when kept dark. This is because UV light, a component of sunlight, raises the respiration rate of soil bacteria and fungi, amplifying the amount of organic matter they break down and the amount of CO₂ released.

The thawing Arctic is emerging as a potentially major source of positive feedback that could accelerate global warming beyond existing projections. "Our task now is to quantify how fast this previously frozen carbon may be converted to CO₂, so that models can include the process," Cory says.

Shocked world media speculates on pope's successor

MANILA: The world's media speculated on whether the next pontiff may come from the developing world, while paying mixed tributes to Pope Benedict XVI following his shock resignation announcement.

The 85-year-old Benedict said on Monday that he would step down at the end of this month because of health reasons, becoming the first leader of the Catholic Church to resign of his own free will in 700 years.

Argentina's largest selling newspaper, Clarin, ran a headline on its website asking whether the next pope might hail from the Americas, Asia or Africa rather than Europe, where all popes have come from through the centuries.

"After the virtually unprecedented decision by the head of the church to resign, there is a growing possibility that deeply established traditions and criteria might change in the next choosing of the pope and there could be a surprise," the report said.

Clarin said this was not just a matter of geography but something that went much deeper.

Catholicism is in serious decline in Europe but growing robustly in Africa and Asia. And Latin America, despite fervent adherence to the faith being patchy, is home to 40 percent of the world's Catholics, the paper noted.

In the Philippines, the Catholic Church's stronghold in Asia, the pope's decision dominated the front pages of newspapers, while major Internet news sites focused on whether Filipino Cardinal Luis Antonio Tagle may succeed him.

"He has the rare chance, like 116 others, to choose the leader of the world's 1.2 billion Catholics. And who knows? He himself may become Pope Benedict XVI's successor," news portal Rappler wrote of Cardinal Tagle.

The pope's resignation made the front pages of most British newspapers, which largely praised his personal qualities, but they also called for the next pope, whether he is from Europe, Asia, Africa or the Americas, to bring about reform.

In an editorial, The Guardian said that Benedict's papacy was "theologically, politically and organisationally a continuation of that of John Paul II, with all its defects and its virtues".

It painted a sober picture of the future, saying that "not a single liberal candidate to succeed Benedict can be identified".

The Times described Benedict's resignation in an editorial as a "noble and selfless decision" but said his successor should try to make the Catholic church "a more collegial venture".

The Independent newspaper focused on the future with the headline "Situation Vacant: New leader wanted for 1.2 billion Roman Catholics".

It added that Benedict's announcement "plunges his Church into turmoil".

In France, daily Catholic newspaper La Croix praised Benedict for making a tough decision.

"This is a man of faith who has decided to resign with the consciousness of having given everything he could for the good of the Church," the newspaper said.

Conservative French newspaper Le Figaro published a special edition in which it welcomed the "humility" of Benedict XVI, who "felt that the challenges of the contemporary church exceeded its powers".

The pope's resignation also made the front pages in Australia, with Rupert Murdoch's national daily newspaper The Australian carrying a headline that said: "Pope Benedict surrenders: too old, too frail to lead a billion people".

In an opinion piece, the newspaper's foreign editor said Benedict was "a good man but a poor pope".

"Benedict was always going to have a hard time following in the footsteps of John Paul II, the most charismatic, and perhaps the most influential, pope in the 20th century," wrote Greg Sheridan.

"But he disappointed even his closest supporters."
