Get rid of your ex on Valentine's, from Facebook at least

An ex is like a scar you once got after a seventh Cabernet in a bar with 12 steps.

Some days, you look at it and are proud. At other times, you wonder how you could have done it to yourself.

The lies, the hurt, the occasional odor of indifference and the underarm spray that was at least two years old -- they all serve as jogs and jags to the memory.

Sadly, many people still hold material relics of disappointed love all over the most important part of their lives -- yes, their Facebook timelines.

In the bowels of these definitive capsules lies the evidence of smiles that proved fake, hugs that proved self-serving, and the sharing of caramel cone ice cream that proved to be nothing more than a deceptive and fattening practice.

So to give your Valentine's Day a fresh start and a clean break, a mobile app called KillSwitch is launching, its sole purpose being to eradicate your ex from your Facebook timeline.

As Mashable reports, KillSwitch promises faithfully to hoover away at your past and suck up all the detritus of the one who once said she loved you more than she loved, well, herself. (C'mon. This is America. That couldn't possibly have been true.)

There's one important -- and potentially deal-breaking -- element to using this app. You and your ex must still be Facebook friends.

I know that for some the very first act after a breakup is to sever the Facebook friendship. (The second is severing ties on LinkedIn.)

Some, though, for reasons of laziness or hidden longing, keep that tenuous connection alive, just in case one party becomes less obstinate or less blind to what really happened.

KillSwitch puts an end to that maybe.

More Technically Incorrect

It digs deep and wide, in order to find any last image, wall post, status update, or poke. You then decide whether to delete them permanently or keep them in a secret KillSwitch folder for a snowy day (in Hell).

Though it costs a whole 99 cents, some of the money will go to the American Heart Association of New York. (It's available as an
Android app in the Google Play store and "coming soon" to the Apple App Store.)

With some exes, it can take awhile to remove all trace -- 4,000 posts took 15 minutes, according to the people behind the app. (4,000 posts? Who does that?)

But if your relationship was a mere superficial shell, then you can be done with all the evidence before you've had 10 slurps of your cappuccino.

Naturally, one could suggest that you could avoid the need for such technology, if you didn't feel such a desperate need to plaster the Web with pictures of every stage of every relationship.

But life these days is about display before dismay, isn't it?

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 shows 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."

Tempers and Compensation on Cruise Ship Rising

The 4,000 passengers and crew aboard the stricken Carnival Triumph cruise ship will disembark after dark tonight from the fetid cruiser dubbed "the poop deck" on social media, according to officials.

"It will come in. It will not stop," Alabama State Port Authority Director Jimmy Lyons said at a news conference today. "We're going to do everything we can from our standpoint to ensure that this is as smooth as possible."

He estimated the ship would arrive between 7 p.m. and 10 p.m. tonight.

Delighted passengers waved at media helicopters that flew out to film the ship and passenger Rob Mowlam told ABCNews.com by phone today that most of the passengers on board were "really upbeat and positive."

Nevertheless, when he gets off Mowlam said, "I will probably flush the toilet 10 times just because I can."

Mowlam, 37, got married on board the Triumph Saturday and said he and his wife, Stephanie Stevenson, 27, haven't yet thought of redoing the honeymoon other than to say, "It won't be a cruise."

Lyons said that with powerless "dead ships" like the Triumph, it is usually safer to bring them in during daylight hours, but, "Once they make the initial effort to come into the channel, there's no turning back."

"There are issues regarding coming into the ship channel and docking at night because the ship has no power and there's safety issues there," Richard Tillman of the Mobile Bay Convention and Visitors Bureau told ABCNews.com.

When asked if the ship could be disembarked in the dark of night, Tillman said, "It is not advised. It would be very unusual."

Carnival Cruise Senior Vice President of Marketing Terri Thornton, however, insisted during a news conference at the port of Mobile today, "Our understanding is it will be alongside this evening."

Thornton denied the rumors that there was a fatality on the ship. He said that there was one illness early on, a dialysis patient, but that passenger was removed from the vessel and transferred to a medical facility.

The U.S. Coast Guard is assisting now and there are multiple generators on board. And customs officials will board the ship while it is being piloted to port to accelerate the embarkation, officials said.

After eight miserable days at sea, the ship's owners have increased the compensation for what some on board are calling the vacation from hell.

All 3,143 passengers aboard the 900 foot colossus, which stalled in the Gulf of Mexico after an engine room fire early Sunday, were already being given a full refund for the cruise, transportation expenses and vouchers for a another cruise. Carnival Cruise Lines is now boosting that offer to include another $500 per person. Gerry Cahill, president and CEO of Carnival Cruise Lines, announced the additional compensation Wednesday.

"We know it has been a longer journey back than we anticipated at the beginning of the week under very challenging circumstances," he said in a statement. "We are very sorry for what our guests have had to endure. Therefore, in addition to the full refund and future cruise credit already offered, we have decided to provide this additional compensation."

Carnival also said that it has canceled a dozen planned voyages for the Triumph and acknowledged that the crippled ship had been plagued by other mechanical problems in the weeks before an engine-room fire left it powerless in the Gulf of Mexico.

Asteroid to give Earth a record close shave on Friday

Earth is about to dodge a bullet. An asteroid will buzz the planet on 15 February, coming closer than many communications satellites.

At 45 metres wide, the space rock is the biggest object in recorded history to swoop this close to Earth. Were it to collide with the planet, it would cause devastation akin to the 1908 Tunguska event that flattened 2000 square kilometres of trees in Siberia.

Astronomers have been tracking the object, called 2012 DA14, since it was discovered a year ago. It will pass about 27,500 kilometres above Earth's surface, making its closest approach over Indonesia at 7.24 pm GMT. In dark, clear skies the asteroid will be visible with binoculars.

Closer look

There is no risk of a collision, but the near miss offers a chance to observe the asteroid up close, for instance, using radar to map its surface. This was done in late 2011 with the asteroid 2005 YU55, which didn't come as near to Earth but was a whopping 400 metres across. Astronomers got a detailed view of a surface covered with craters.

"2012 DA14 is a much smaller object, so won't look this good," says Amy Mainzer of NASA's Jet Propulsion Lab in Pasadena, California. Still, the radar images should give a better sense of the object's shape and spin, which will improve our understanding of its likely future path, she says.

"Right now astronomers expect that Earth's gravity will shift the asteroid's orbit closer to the sun, which means it is unlikely to get cosy with our planet again for another 100 years.

Astronomers also hope to read the object's spectrum - chemical clues in its reflected light that can reveal its composition, says JPL's Donald Yeomans. This can help studies of all near-Earth asteroids, he says: "If you can match up spectral types of asteroids to a corresponding meteorite type, which has been studied to death on the ground, then you know what this thing is made of at the elementary level."

Olympics: Wrestlers vow to fight Olympic removal

PARIS: Wrestlers around the world on Wednesday vowed to fight to save the ancient sport's Olympic status, after the International Olympic Committee voted to drop it for the 2020 Games.

Japan and Turkey -- whose cities Tokyo and Istanbul are bidding to host the Games in seven years' time -- led the calls for the world body to reconsider, as an online petition was organised urging a rethink and gained thousands of supporters.

The president of the Turkish wrestling federation, Hamza Yerlikaya, called the decision, taken at the IOC executive board meeting in Lausanne, Switzerland, on Tuesday, "unfair" and a "mistake" that they would seek to overturn.

"To have the 2020 Olympics in Istanbul without wrestling is unthinkable," said Yerlikaya, himself a double Olympic gold medallist, three-time world champion and eight-time European champion in Greco-Roman wrestling.

"We won't allow it," he added.

In Japan, Yerlikaya's counterpart Tomiaki Fukuda said on his federation's website that he was "dissatisfied and baffled", echoing the views of the sport's world governing body, which called the decision "an aberration".

Wrestling will remain on the programme for the 2016 Olympics in Rio de Janeiro but faces a fight against seven other sports for inclusion at the Games four years later. A final decision is to be made when all IOC members meet in September.

Members are seen as unlikely to vote against the executive board, however, raising the prospect that one of the few sports that survived from the original Olympics in ancient Greece into the modern era will disappear.

Wrestling first appeared in 708 BC and has only ever been left out of the Olympic programme once before in 1900.

The International Federation of Associated Wrestling Styles (FILA) has vowed to fight the decision, while multiple medallists Russia and Iran have also said they hoped the IOC would backtrack.

"This issue will definitely be a big blow to the country's sport, as it is one of our country's most popular sports," the head of Iran's national Olympic commitee, Mohammad Aliabadi was quoted as saying in Iranian media, "I will certainly pursue the case."

IOC president Jacques Rogge meanwhile insisted on Wednesday that the vote -- by secret ballot -- was fair and said he understood the angry response from those involved in the sport.

A meeting was planned between the committee and the International Federation of Associated Wrestling Styles (FILA), to discuss the matter, he told a news conference in Lausanne.

Wrestlers have been left dismayed by the decision, with Japan's undisputed queen of the ring, Saori Yoshida, saying: "I am so devastated that I don't know what to do."

Yoshida, a 55kg-class freestyle wrestler who is the face of Tokyo's campaign for the right to host the 2020 Games, has won a record 13 straight Olympic and world championship gold medals over 10 years.

In India, Sushil Kumar, who won a bronze in Beijing and a silver in London last year, said: "I still can't get over the news that we won't be at the Olympics.

"All sportsmen look towards the Olympics as the pinnacle of excellence, everyone wants to take part in them. Now what do we do? Give up wrestling? I hope the IOC will reconsider this decision."

An online petition at change.org entitled "The International Olympic Committee: Save Wrestling as an Olympic sport #SaveOlympicWrestling" has also been mounted, urging the US Senate to take up the matter.

By late afternoon on Wednesday, it had more than 21,000 signatures.

On Twitter, one user, @WrestlersLoveUs, wrote: "Ancient Olympic wrestlers used to sometimes fight to the death. IOC better understand we're ready to do that again. #SaveOlympicWrestling."

Skype 6.2 arrives for Windows, Mac

Microsoft's Skype team today rolled out two new updates, both labeled as version 6.2, for Windows and Mac.

The Windows version includes a redesigned top toolbar that brings together main actions, like calling phones, creating groups, and adding contacts. It also includes "eGifting," or the ability to send Skype credits to users on their birthday which the recipients can use anytime.

Another feature in the Skype 6.2 for Windows release includes the option to send an instant message using ctrl+enter. This version drops support for PCs using Intel Pentium 3 or similar CPUs which don't support SSE2 instructions.

The Skype for Mac 6.2 update includes the same eGifting capability. It also adds support for one-way SMS without the addition and verification of the user's mobile number.

The
Mac update includes several bug fixes, including problems with signing out of Facebook, and issues around the display of Messenger contacts in a Skype contact group.

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 news 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, a spokeswoman for the 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 whether 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 news 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 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, which was the sound of ammunition being ignited by the heat of the blaze, law enforcement officials said.

Police did not enter the building, but shot tear gas inside.

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.

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, sources said.

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

The San Bernardino Sheriff's Office and state Fish and Wildlife wardens 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 pickup 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.

The white pickup truck bought Dorner extra time because police were still looking for the purple Nissan, California Department of Fish and Wildlife Lt. Patrick Foy told "Good Morning America" today.

"We were looking for a purple color Nissan and all of a sudden this white pickup starts coming by in the opposite direction. That's not the suspect's vehicle that we had been looking for," Foy said.

A warden with the Fish and Wildlife department noticed Dorner driving and the pursuit picked up again, Foy said.

"Ultimately, the officer who was driving that vehicle stopped and pulled out his patrol rifle and engaged probably 15 to 20 shots as Dorner was driving away," Foy said.

Dorner then ran on foot to the cabin in which he barricaded himself and got in a shootout with San Bernardino County sheriff's deputies and other officers who arrived.

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 officers' surrounding the cabin, but sent him a message.

"If he's watching this, the message is: Enough is enough," Los Angeles Police Department spokesman Andy Smith told reporters at a news conference Tuesday. "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."

Horsemeat disguised as beef confirmed in France: company

PARIS: A major French frozen food retailer said on Tuesday it had found horsemeat in two lots of frozen beef lasagne meals it removed from its shelves last week.

Picard, which has hundreds of outlets across France that sell ready-to-eat meals, said the products were made by Comigel, the French firm which last week sparked the frozen food scandal now spreading across Europe.
