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 urges a move away from narrow focus on politics of austerity

Just about every argument in Washington since the 2010 midterm elections, which returned control of the House to Republicans, has centered on reducing the federal deficit. On Tuesday night, President Obama leaned into his second term by declaring that a single-minded focus on deficit reduction would jeopardize the nation’s future. And he sounded an urgent call to rebuild.

Reelected by an ascendent coalition, the president spoke from a position of strength in his fourth State of the Union address. The economy is improving. The Republican Party is in disarray. The time has come, Obama indicated, to pivot away from the politics of austerity.

“Most of us agree that a plan to reduce the deficit must be part of the agenda,” he said. “But let’s be clear: Deficit reduction alone is not an economic plan. A growing economy that creates good middle-class jobs — that must be the North Star that guides our efforts.”

The president rejected the fiscal brinkmanship that defined the past two years. Instead, he framed future fiscal debates as opportunities to shape a “smarter government” — one with new investments in science and innovation, with a rising minimum wage, with tax reform that eliminates loopholes and deductions for what the president labeled “the well-off and well-connected.”

Second-term presidents have a narrow window of time to enact significant change before they become lame ducks, and Obama, while echoing campaign themes of reinforcing the middle class, made an urgent case for a more pragmatic version of populism, one that emphasizes economic prosperity as the cornerstone of a fair society.

Over and over, he noted that the time to rebuild is now.

The “Fix-It-First” program that Obama outlined to put people to work on “urgent repairs,” such as structurally deficient bridges, bore echoes of President Bill Clinton’s call in his 1999 State of the Union address to “save Social Security first.” Clinton’s was an effective line, one that stopped — at least until President George W. Bush took office two years later — a Republican drive to use the budget surplus to cut taxes.

Although Obama’s speech lacked the conciliatory notes of some of his earlier State of the Union addresses, he did make overtures to Republicans and cited Mitt Romney, his presidential challenger, by name.

He combined tough talk about securing the border, which brought Republicans to their feet, with a pledge to entertain reasonable reforms to Medicare, the federal entitlement program that fellow Democrats are fighting to protect.

“Those of us who care deeply about programs like Medicare must embrace the need for modest reforms,” he said.

Obama also pledged to cut U.S. dependence on energy imports by expanding oil and gas development. And he singled out one area where he and Romney found agreement in last year’s campaign: linking increases in the minimum wage to the cost of living.

Obama set a bipartisan tone at the start of his speech, quoting from President John F. Kennedy’s address to Congress 51 years earlier when he said, “The Constitution makes us not rivals for power, but partners for progress.”

Cambodia reports sixth bird flu death this year

PHNOM PENH: A three-year-old Cambodian girl has died from bird flu, bringing the country's toll from the deadly virus to six so far this year, the World Health Organisation said on Wednesday.

The girl, from the southern province of Kampot, died in a children's hospital in the capital Phnom Penh, the WHO said in a joint statement with the Cambodian health ministry.

Tests confirmed she had contracted the H5N1 strain of avian influenza and "the girl had a history of coming into contact with poultry (in her village) prior to becoming sick", it added.

Cambodian Health Minister Mam Bunheng said in the statement that "H5N1 remains a serious threat to the health of Cambodians, especially children".

The country has recorded 28 cases of H5N1 since 2003, with all but three of them proving fatal.

Four Cambodians, including a 17-month-old girl, died from the strain last month and a five-year-old girl died last week.

The virus has killed more than 365 people worldwide since a major outbreak in 2003, according to WHO statistics.

It typically spreads from birds to humans through direct contact. But experts fear it could mutate into a form easily transmissible between humans, with the potential to trigger a pandemic.

Kerala rape case: Kurien's wife rubbishes charge against husband

PATHANMTHITTA, KERALA: Amid growing clamour for resignation of Rajya Sabha Deputy Chairman P J Kurien in the Suryanelli gangrape case, his wife has rubbished the allegations against him and said those hurling "malicious charges" never bothered to appreciate sentiments of her family.

Susan Kurien, a retired high school teacher, said in a statement here that her husband had reached home and they had supper together on the day he was alleged to have abused the victim in a guest house at distant Kumali.

"I am sure that the allegations against my husband are baseless. Myself and my two daughters firmly believe that the truth prevail in this matter," Susan said.

She said her family was deeply pained that Kurien was being haunted through media (by those levelling charges) after a span of 17 years, raising the same allegations which were found baseless by repeated investigations and judicial scrutiny.

"Those who are fighting for women's right should not forget the fact that Prof Kurien too has a family", she said.

Kurien has all along rejected the charge and opposition's demand for his resignation, saying it was a matter which had already been cleared by the Supreme Court.

The girl from Suryanelli in Idukki district was abducted in January 1996 and transported from place to place across Kerala and sexually exploited by different persons.

The victim had sent a letter to the Supreme Court last week, seeking a review of the apex court's order quashing all charges against Kurien.

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.

State of the Union: Obama Pushes Job Creation

Pursuing an aggressive and diverse early second-term agenda, President Obama turned his focus Tuesday night squarely to the economy, using his State of the Union address to unveil new government initiatives aimed at creating jobs.

The defining duty of the new Congress and new administration is to "reignite the true engine of America's economic growth -- a rising, thriving middle class," Obama said Tuesday night from the House chamber.

"That must be the North Star that guides our efforts," he said.

Obama's proposals had a familiar ring, including re-packaged economic ideas but also offering several bold new measures aimed at boosting the middle class.

None of the proposals would add to the deficit "by a single dime," Obama pledged, with costs offset by savings carved out in the budget and from money saved from ending two wars.

"It's not a bigger government we need, but a smarter government that sets priorities and invests in broad-based growth," Obama said.

For the first time as president, Obama called for raising the minimum wage from $7.25 to $9.00 an hour by 2015. He proposed to ensure future increases by indexing the minimum wage to inflation.

He proposed a national goal of universal pre-school education, an effort to help states provide tens of thousands of low- to middle-income four-year-old children access to quality public education from an earlier age.

And, to heal the nation's crumbling roads and bridges, Obama offered a $50 billion "fix it first" infrastructure program that would prioritize repair of existing structures before building new ones.

"Every day, we should ask ourselves three questions as a nation," Obama said. "How do we attract more jobs to our shores? How do we equip our people with the skills needed to do those jobs? And how do we make sure that hard work leads to a decent living?"

Answers to those questions, the president suggested, include redoubling investments in clean energy technologies -- a step which he said would both benefit the environment and reduce U.S. dependence on foreign oil.

"For the sake of our children and our future, we must do more to combat climate change," he said.

He called for doubling the amount of renewable electricity generation in the U.S. by 2020, and announced an energy version of his "Race to the Top" education program that would give states grants for the best energy efficiency programs.

In tandem with his economic focus, Obama announced the withdrawal of 34,000 U.S. troops from Afghanistan by this time next year, cutting in half the current force and marking a quickened pace for the final exit of U.S. combat forces by a 2014 deadline.

There are currently 66,000 U.S. troops serving in Afghanistan. Obama has vowed to bring nearly all of them home by the end of next year, though a small contingent will likely remain to train Afghan forces and assist counterterrorism operations, officials have said.

Obama touched briefly on his recently-unveiled proposals to overhaul the nation's immigration system, expand rights for gay and lesbian Americans and curb an epidemic of gun violence.

With dozens of victims of gun violence looking on from the House gallery, including former Rep. Gabby Giffords, and families of victims from shootings at Newtown, Conn., Oak Creek, Wisc., and Aurora, Colo., Obama made an emotional plea for an up-or-down vote on his gun control plan.

"Each of these proposals deserves a vote in Congress," he said of proposed restrictions on assault-style weapons and high capacity magazines, and enhanced background checks, among other measures.

"If you want to vote no, that's your choice," he said. "But these proposals deserve a vote. Because in the two months since Newtown, more than a thousand birthdays, graduations and anniversaries have been stolen from our lives by a bullet from a gun."

Impact of State of Union speeches isn’t very lasting

When President Obama delivers his fourth State of the Union speech Tuesday night, he is guaranteed an audience of millions of viewers, the rapt of attention of Beltway reporters and issues advocates, and for at least an hour, the undivided attention of Congress.

What isn’t guaranteed is any lasting impact.

Rarely have State of the Union addresses moved public opinion, and rarely have they led to the kind of broad legislative accomplishments that presidents propose. For all the ritual and attention surrounding these speeches, the State of the Union is, well, sort of lame.

“Most of the speeches can be summarized in three words: boring, boring, boring,” said Allan Lichtman, author of “The 13 Keys to the Presidency.” “They tend to be laundry lists. But sometimes they rise above that.”

Mandated by the Constitution, the State of the Union, for much of its history, was not a speech at all but a written list of policy recommendations handed to Congress. Now, the addresses are grand political theater and provide a rare chance for a president to make an unfiltered argument and lay out policy ambitions from the biggest bully pulpit he will have all year.

Billed as a coda to his second inauguration, Obama’s speech will focus on the economy and the middle class — he is set to propose spending public money on education, research and infrastructure — as well as touch on immigration and gun control.

He will spend the remainder of the week giving repackaged versions of his address, looking to capi­tal­ize on the moment and further underscore his priorities.

“The State of the Union is a Super Bowl-like political event. The key to fully leveraging it is to make sure that it doesn’t become a one-off but contains a big-idea thematic animated by some specific proposals,” said Chris Lehane, a Democratic strategist who worked for President Bill Clinton. “If the speech is not approached like that, it risks becoming a pupu platter moment — lots of tasty dishes, but you won’t be filled up for the long term.”

Although interest groups and lobbyists, inside and outside the administration, spend time trying to get the briefest of mentions of their pet causes in the speech before an audience of about 40 million, there are few legislative payoffs to show for all their efforts.

President George W. Bush used the first State of the Union speech of his second term to call for privatizing Social Security, an effort that hit a brick wall in Congress and nationwide.

In his 2012 speech, Obama proposed that every state require that students stay in high school until they graduate or turn 18, a recommendation that also fell flat.

Obama used that address to make his argument for reelection, touching on themes of fairness and economic equality that would undergird his campaign stump speeches. But there have been few memorable lines or themes from Obama’s addresses on par with Clinton’s 1996 pronouncement that “the era of big government is over” or Bush’s “axis of evil” reference from 2002.

“His speeches have tended to be about half looking back and half looking forward. And that’s a style you can choose in a State of the Union — how much of the speech is going to be devoted to where we are today, how far we’ve come and so forth, versus something more visionary and using your time to look forward,” said Chriss Winston, a speechwriter for President George H.W. Bush. “That’s a choice every president has to make.”

Obama rebukes North Korea over test

WASHINGTON: US President Barack Obama said Tuesday that North Korea's "provocative" nuclear test did not make it more secure and called for "swift" and "credible" international action in response.

Obama also vowed in a written statement that Washington would remain vigilant in the face of the underground detonation by the Stalinist state and steadfast in its defense commitments to its allies in Asia.

"These provocations do not make North Korea more secure," Obama said.

"Far from achieving its stated goal of becoming a strong and prosperous nation, North Korea has instead increasingly isolated and impoverished its people through its ill-advised pursuit of weapons of mass destruction and their means of delivery."

Obama complained that the test was a "highly provocative act" that -- following the North's December 12 ballistic missile launch -- undermined regional stability and violated UN Security Council resolutions.

"The danger posed by North Korea's threatening activities warrants further swift and credible action by the international community," Obama said, ahead of an emergency meeting of the UN Security Council called for later on Tuesday.

"The United States will also continue to take steps necessary to defend ourselves and our allies," Obama said.

Joint Parliamentary Committee questions CBI director on 2G prosecutor's removal

NEW DELHI: CBI director Ranjit Sinha was on Tuesday quizzed by Opposition members about the removal of the prosecutor in the 2G case during a meeting of the Joint Parliamentary Committee examining the scam.

Sinha is learnt to have told the Committee, chaired by PC Chacko, that the veracity of the purported taped conversations between CBI prosecutor AK Singh and Unitech Managing Director Sanjay Chandra was yet to be established.

CBI had removed Singh from the 2G spectrum case after he was caught in an alleged taped conversation discussing prosecution strategy with Chandra.

As Sinha appeared before the JPC examining the alleged irregularities in allocation of 2G spectrum, questions on the removal of Singh were first put to him by opposition members.

The CBI chief's testimony was slated as one of the last presentations to the JPC along with that of telecom secretary R Chandrashekhar.
