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."

'Blade Runner' Charged With Murder of Girlfriend













Oscar Pistorius, the Olympic and Paralympic athlete known as the "blade runner," was taken into custody in South Africa today and charged with the murder of his girlfriend, who was fatally shot at his home.


Police in the South African capital of Pretoria received a call around 3 a.m. Thursday that there had been a shooting at the home of 26-year-old Pistorius, Lt. Col. Katlego Mogale told the Associated Press. When police arrived at the scene they found paramedics trying to revive 29-year-old Reeva Steenkamp, the AP reported.


At a press conference early Thursday police said that a 26-year-old man, whom they have not named, was arrested and has requested to be taken to court immediately. Police in South Africa do not name suspects in crimes until they have appeared in court.

Mogale said that the woman died at the house, and a 9 mm pistol was recovered at the scene and a murder case opened against Pistorius, the AP reported.


Police said this morning that there are no other suspects in the shooting, and that Pistorius is currently at the police station.


The precise circumstances surrounding the incident are unclear. Local reports say he may have mistaken her for a burglar, according to the AP.


Police said that they have heard reports of an argument or shouting at the apartment complex, and that the only two people on the premises were Steenkamp and Pistorius.


Police confirmed there have previously been incidents of a domestic nature at the home of Pistorius.


Pistorius, a sprint runner, had double below the knee amputations, and part of his legs have been replaced with carbon fiber blades. In 2012 he became the first double leg amputee to participate in the Olympics, competing in the men's 400 meter race. He also competed in the Paralympics, where he won gold medals in the men's 400 meter race, in what became a Paralympics record. He also took the silver in the 200 meter race.


Steenkamp, according to her Twitter bio, is a law graduate and model. On Wednesday she tweeted, "What do you have up your sleeve for your love tomorrow??? #getexcited #ValentinesDay."

Obama urges a move away from narrow focus on politics of austerity



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.”

EU ministers to meet on horsemeat crisis






BRUSSELS: European Union farm ministers hold crisis talks in Brussels on Wednesday to agree a response to a scandal over mislabelled frozen meat products which is spreading across Europe.

The snap talks come a day after British police searching for the source of horsemeat found in kebabs and burgers raided two meat plants, the first such operation in the row, and France became the second EU nation after Britain to find horsemeat posing as beef in frozen food.

"If there is horsemeat in hamburgers or lasagne there should've been a label indicating this," EU commissioner for health Tonio Borg said ahead of the talks.

"Consumers are entitled to know what they are eating," he said at a news conference, "If anyone distributes and circulates meat products as beef, when it is not beef, that is in violation" of EU legislation.

It was up to member states to enforce current labelling legislation, he said, reiterating also that the European Commission believed that the scandal "up until now is a labelling issues" and "not a health issue".

"It is evident," he added, "that someone down the line has fraudulently or negligently -- probably fraudulently -- labelled a product in a deceptive way."

Wednesday's talks between EU agriculture ministers opening at 1630 GMT aim to have "an exchange of views and allow for sharing of information between the most affected member states" -- Britain, France, Luxembourg, Poland, Romania and Sweden.

The ministers will also look at "whatever steps may be necessary at EU level to comprehensively address this matter", said Ireland, which currently holds the rotating EU presidency.

On Tuesday, supermarkets in Switzerland and the Netherlands became the latest to pull ready-made meals as anger grows across Europe.

France has called for precise labelling on the origin of meat in ready-made dishes.

And President Francois Hollande warned on Wednesday that the scandal could seriously damage the country's frozen food sector.

"The president underlines that it is a serious affair in relation to consumer confidence and potentially serious for the consequences for the French sector," government spokeswoman Najat Vallaud-Belkacem said.

Interbev, an association representing the French cattle and meat industry, has denounced the EU's failure to act, saying bth consumers and professionals wanted swift action on better labelling.

In Britain, police and officials from the Food Standards Agency on Tuesday raided a slaughterhouse in northern England and a meat-producing factory in Wales. They shut both sites and seized all meat there.

"The agency and the police are looking into the circumstances through which meat products, purporting to be beef for kebabs and burgers, were sold when they were in fact horse," the agency said.

Andrew Rhodes, operations director of the FSA, said he had ordered an audit of abattoirs that produce horsemeat in Britain when the scandal arose last month "and I was shocked to uncover what appears to be a blatant misleading of consumers."

The raids on the British meat premises opened a new front in the pan-European search for the source of the horsemeat: the allegations had so far focused on Romania.

In France, retailer Picard said tests had confirmed that horsemeat was present in two lots of frozen "beef" lasagne meals made by French firm Comigel.

Retailers in Britain, Sweden, France, Switzerland and the Netherlands have been removing Comigel products after the firm alerted Swedish frozen food giant Findus to the presence of horsemeat in its meals last week.

Swiss supermarket giant Coop said it had now withdrawn all frozen lasagnes produced by Comigel as a precaution.

Comigel denies any wrongdoing. It said it obtained its meat from another French firm, Spanghero, which said it was supplied from two abattoirs in Romania who allegedly passed off horsemeat as beef.

But Romanian Prime Minister Victor Ponta this week angrily denied his country was to blame and called on European Union officials to find out from where the fraud originated and identify the guilty parties.

Dutch supermarkets PLUS and Boni said Tuesday they had withdrawn Primafrost brand frozen lasagne as a precaution because it may contain horsemeat without being marked on the packaging.

2G scam: Rajnath Singh demands widening of probe

RAIPUR: Bharatiya Janata Party(BJP) president Rajnath Singh on Wednesday demanded widening of the scope of a probe into prosecutor-accused collusion in the 2G spectrum scam case saying he suspected involvement of more influential people.

"A detailed probe is needed to find out who all were behind revealing the prosecution strategy with one of the accused. Even there may be some ministers and officers", he said at a press conference on his arrival here in Chhattisgarh to attend a meeting of Bharatiya Janata Yuva Morcha( BJYM).

Referring to the controversy over alleged corruption in purchase of helicopters from Italian firm Finmeccanica, BJP chief said although defence minister A K Anthony had ordered an inquiry into the complaints of corruption, it's the Italian agencies that had taken prompt action while the probe by Indian agencies did not progress.

To a question that the initial process for the purchase of helicopters from the Italian firm was carried out during the previous NDA regime, Singh quipped "Let there be an inquiry. The facts will come out".

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 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.


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.

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





One sheriff's deputy was killed in a shootout with Dorner earlier Tuesday afternoon, believed to be his fourth victim after killing a Riverside police 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.

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.


Sources tell ABC News it all began at 12:20 p.m. PT Tuesday, when a maid working at a local resort called 911, saying she and another worker had been tied up and held hostage by Dorner in a cabin.


The maid told police she was able to escape, but Dorner had stolen one of their cars, which was identified as a purple Nissan.


San Bernardino Sheriff's Office and state Fish and Game officers spotted the stolen vehicle and engaged in a shootout with Dorner.


Officials say Dorner crashed the stolen vehicle and fled on foot only to commandeer Rick Heltebrake's white pick-up truck on a nearby road a short time later.


"[Dorner] said, 'I don't want to hurt you, just get out and start walking up the road and take your dog with you.' He was calm. I was calm. I would say I was in fear for my life, there was no panic, he told me what to do and I did it," Heltebrake said.


"He was dressed in all camouflage, had a big assault sniper-type rifle. He had a vest on like a ballistic vest," Heltebrake added.


Ten seconds later, Heltebrake said, a "volume of gunfire" could be heard.


Sources tell ABC News the gunfire was from Dorner who exchanged fire with two deputies.


The 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. All schools were briefly placed on lockdown.


Believing that Dorner might have been watching reports of the standoff, authorities asked media not to broadcast images of police surrounding the cabin, but sent him a message.


"If he's watching this, the message ... is: Enough is enough. It's time to turn yourself in. It's time to stop the bloodshed. It's time to let this event and let this incident be over," said Los Angeles Police Department spokesman Andy Smith, told reporters at a press conference Tuesday.

North Korea threatens "stronger" action after nuke test






SEOUL: North Korea said its nuclear test on Tuesday was only a "first" step and warned of stronger action if it was faced with tougher sanctions as a result.

"The latest nuclear test was only the first action, with which we exercised as much self-restraint as possible," the foreign ministry said in a statement carried by the country's official news agency.

"If the US further complicates the situation with continued hostility, we will be left with no choice but to take even stronger second or third rounds of action," it said without elaborating.

The statement came just hours after South Korea's spy agency chief warned Pyongyang might carry out another nuclear test or ballistic missile launch in the coming days or weeks.

North Korea said Tuesday's test was directly targeted at the United States. It accuses Washington of inciting global condemnation of its nuclear programme and of leading the sanctions charge in the UN Security Council.

The ministry statement said any measure like forced ship inspections or a sea blockade would be considered an "act or war" and trigger "merciless retaliations".

The UN Security Council was scheduled to meet in emergency session later Tuesday to discuss the international response to the latest test.

"The US should make a choice between taking the path of easing tension... or continuing on its current, wrong path of pursuing anti-DPRK (North Korea) policies and further escalating tensions," the ministry said.

Father wants son out of Kerala cabinet

THIRUVANANTHAPURAM: Kerala Congress (Pillai) leader R. Balakrishna Pillai Tuesday asked Chief Minister Oommen Chandy to drop his (Pillai's) son and minister K.B. Ganesh Kumar from the cabinet.

The father and son have been at war for over a year. A letter making this demand was handed over to Chandy by an aide to the senior Pillai.

Ganesh Kumar is the forest, sports and cinema minister.

At a meeting of the Congress-led United Democratic Front Monday, Pillai's aide demanded that Ganesh Kumar be removed as minister as he does not enjoy the confidence of the party any more.

The UDF demanded a written request.

Pillai, 78, has not been attending UDF meetings because he was upset that Chandy and the UDF were not acceding to his demand.

Pillai is an eight-time legislator and a one-time Lok Sabha member.

His son Ganesh Kumar won for a third time from Pathanapuram constituency.

UDF and Chandy have tried their best to broker peace between the father and son but all efforts have failed.

The UDF will decide on Pillai's request at its meeting Feb 21.
