Dorner Confirmed Dead in Autopsy on Cabin Remains

Christopher Dorner, the ex-Los Angeles police officer who declared himself on a killing spree against his former law enforcement colleagues, is dead.

Authorities this evening confirmed that remains found after a fiery standoff at a California mountain cabin Tuesday were, in fact, Dorner's.

"The charred human remains located in the burned out cabin in Seven Oaks have been positively identified to be that of Christopher Dorner," the San Bernardino County Sheriff-Coroner's Office said in a written statement. "During the autopsy, positive identification was made through dental examination."

In a 6,000-word "manifesto," Dorner outlined his anger at the Los Angeles Police Department for firing him, and made threats against individuals he believed were responsible for ending his career with the police force five years ago. Dorner was fired after filing what the LAPD determined to be a false report accusing other cops of brutality.

Dorner is suspected of killing four people, including Monica Quan and her fiance, who were found shot to death Feb. 3. Quan was the daughter of former LAPD Capt. Randal Quan, who was mentioned as a target of Dorner's fury in the manifesto.

Dorner is also suspected in the shooting death of Riverside, Calif., Police Officer Michael Crain, whose funeral was Wednesday.

San Bernardino Sheriff's Deputy Jeremiah MacKay, 35, a 15-year veteran and the father of two children, was killed in Tuesday's shootout at the cabin.

A second San Bernardino County sheriff's officer had to undergo multiple surgeries after he was wounded in the cabin shootout, and other officers also were wounded in earlier alleged encounters with Dorner.

After Crain's death, police tracked Dorner to the Big Bear Lake area of Southern California, where his burning truck was found in the mountains late last week.

A couple with a cabin in the area were some of the last people to see Dorner before his final encounter with police. Their 911 call to police triggered a chase that concluded with the fiery standoff at the nearby cabin.

The couple, Karen and Jim Reynolds, said at a news conference Wednesday that their ordeal lasted a few minutes but seemed like hours.

The Reynolds believe Dorner, 33, was holed up starting Friday in their unoccupied cabin in Big Bear, Calif., only steps from where police had set up a command center.

"He said four or five times that he didn't have a problem with us, he just wanted to clear his name," Jim Reynolds said. "He said, 'I don't have a problem with you, so I'm not going to hurt you.'"

Dorner tied their arms and put pillowcases over their heads before fleeing in their purple Nissan, the couple said.

Before he fled, the couple said Dorner told them that he had been watching them before he took over their cabin. Dorner told the couple he could tell they were "hard working, good people."

"He had been watching us and saw me shoveling the snow Friday," Jim Reynolds said.

They say they may have left the cabin door unlocked and that could have been the reason Dorner was able to enter undetected.

Dorner remained "calm and meticulous" throughout the harrowing ordeal, the couple said.

The Reynolds walked into their cabin around noon Tuesday when they came face-to-face with Dorner. There was no question in their minds who he was -- the suspected cop killer at the center of one of the largest manhunts in recent memory.

Athletics: Paralympic day to top off London Diamond

LONDON: London's Olympic Stadium will stage three days of athletics in July, including one devoted solely to Paralympic competition, British Athletics has announced.

The London Anniversary Games, which will take place from July 26-28 and in the process mark a year since the opening ceremony of the 2012 Olympics, will incorporate the annual two-day Diamond League meeting on the Friday and Saturday, but also, for the first time, a day of purely Paralympic competition on the Sunday.

Sebastian Coe, who chaired the London 2012 Organising Committee and is now chairman of the British Olympic Association, said it was terrific news.

"I am delighted that the London Anniversary Games has been confirmed as three days of international athletics this July.

"London 2012 was an amazing year for British sport and what a way to celebrate its success by welcoming the world back to London once more to watch the biggest names in athletics."

British middle distance great Coe, the Olympic 1,500 metres gold medallist at both the 1980 and 1984 Games in Moscow and Los Angeles respectively, added he hoped this July's event would build on the success of London 2012.

"It is an important part of the London 2012 legacy that as many people as possible experience world class sport in the world class facilities at Queen Elizabeth Olympic Park and I'm sure the London Anniversary Games will go a long way to inspiring the next generation of track and field fans."

Former Olympic 400m champion Christine Ohuruogu, who grew up in Stratford, added: "The London Diamond League has always been one of my favourite meets so it's fantastic that it's retaining its two day format.

"The atmosphere in the stadium was phenomenal last year and I'll never forget it -- it was very special for me as a local girl."

Officials had already announced the London Diamond League meeting would move to the Olympic venue in the eastern district of Stratford from Crystal Palace in south London.

But on Wednesday they said in addition to the usual track and field meeting on the first two days, the weekend would be topped off by a day of Paralympic competition in the Olympic Stadium, that will come soon after the International Paralympic Committee World Championships in Lyon, eastern France.

Earlier in July, two rock music concerts will see the 80,000-seater Olympic Stadium used for the first time since the Paralympics closing ceremony in September.

Although the Olympic Stadium is due to stage the 2017 World Athletics Championships, doubt remains over its long-term future.

English Premier League football club West Ham have been named as the preferred bidder for the tenancy and a final decision on their bid is expected before April.

The £292 million ($463 million, 348 million euro) complete transformation of the Olympic Park, which began when the London 2012 Games ended, is set to take 18 months.

Judge tosses some shareholder suits over Facebook's IPO flop

Things may be looking up for Facebook in the dozens of lawsuits it's facing from peeved shareholders over its botched initial public offering.

U.S. District Judge Robert Sweet ruled in favor of Facebook today and dismissed a group of these cases, according to the Wall Street Journal.

The social network became embroiled in this extensive legal battle shortly after its $16 billion IPO last May. The company's stock opened on the Nasdaq priced at $38 a share and, aside from a slight uptick right at the start, proceeded to plummet in the days and weeks following. Defendants in the lawsuits, many of whom are investors, claim Facebook failed to disclose in the critical days leading up to the IPO that there was "a severe and pronounced reduction" in forecasts for Facebook's revenue growth.

According to the Wall Street Journal, Judge Sweet ruled today that Facebook had no obligation to release its revenue growth forecasts in four of the shareholder lawsuits. The company had already "made express and extensive warnings" regarding obstacles to its mobile business, the judge said.

Originally, Sweet was assigned 42 cases filed against the social network, but he consolidated them in October. In December, he picked a handful of plaintiffs to head the class action suits, which include several state pension funds.

The majority of these lawsuits rely on the argument that Facebook failed to disclose its revenue growth forecasts in the days before its IPO. However, it's unclear if Sweet will rule the same for all of these cases. Throughout the process, Facebook has maintained that it's innocent of any wrongdoing.

When contacted by CNET, a Facebook representative said, "We are pleased with the court's ruling."

Update, 5:40 p.m. PT:

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."

Ship Stranded: Love Boat to Horror Honeymoon

A Texas couple's fantasy wedding quickly turned into a nightmare honeymoon when the fire-damaged Carnival Cruise ship carrying them became stranded in the Gulf of Mexico.

Rob Mowlam, 37, and Stephanie Stevenson, 27, of Nederland, Texas, got married on the Carnival Triumph on Saturday. The four-day cruise was meant to be back to shore on Monday, but was left disabled by an engine fire on Sunday.

The ship is being slowly towed to shore and is expected to dock in Mobile, Ala., on Thursday if weather permits. The vessel is without air conditioning, many working toilets and some restaurant service. Passengers, many who are sleeping in tents on deck, have told ABC News the smell on the ship is foul.

That is the honeymoon setting for Mowlam and Stevenson.

"[Rob Mowlam] had been with his girlfriend, or fiance, for a long period of time and they just took the next step," Mowlam's brother James Mowlam III told ABCNews.com. "The captain is the king of the world when they're on the boat and he hitched them up."

James Mowlam said he was shocked when he heard about the stranded boat and the increasingly dire conditions on the ship.

"It is an atrocious scene to be subjected to," he said.

Mowlam said he has not been able to communicate with his brother, but that his father has had sporadic communication with him.

"It would be my guess that this would probably not be on anyone's great list of memorable wedding experiences," Mowlam said with a laugh. "Although, my mom told him that she was hoping they had a memorable wedding and I think this would classify as a memorable wedding experience."

The bride's brother, Justin Davis, told ABCNews.com that his sister works for a doctor's office and the cruise was a gift from the doctor to the staff.

Davis has not been able to speak to Stevenson but said that her two young sons are being cared for by her mother. He said his sister is tough and he guesses she's probably not scared.

"She might be a little aggravated at the situation, but I'd say she's [probably] handling it really well," he said.

Others on the ship do not seem to be handling the situation so well.

Elderly and disabled passengers aboard the ship are struggling to cope with the worsening conditions, according to at least one passenger.

"Elderly and handicap are struggling, the smell is gross," passenger Ann Barlow text-messaged ABC News overnight. "Our room is leaking sewage."

The head of Carnival Cruise Lines said the British-U.S.-owned company was working hard to ensure the thousands of passengers stranded on the disabled ship were as comfortable as possible while the vessel was being towed to a port in Alabama.

"I need to apologize to our guests and to our families that have been affected by a very difficult situation," Carnival Cruise Lines president and CEO Gerry Cahill said at a news conference Tuesday evening.

It was the first time since a fire erupted in Triumph's engine room Sunday, knocking out its four engines, that a company representative had spoken publicly. The Triumph, with roughly 4,200 people on board, was left bobbing like a 100,000-ton cork for more than 24 hours. Giant sea-faring tugboats then hooked up to the ship and began towing the nearly 900-foot-long ship to land.

Carnival spokeswoman Joyce Oliva told The Associated Press Tuesday that a passenger with a pre-existing medical condition was taken off the ship as a precaution. Everyone else will likely have to weather conditions such as scarce running water, no air conditioning and long lines for food.

Back on land, passenger Barlow's 11-year-old twins told ABC News Tuesday they are worried as more passengers continue to talk about living with limited power and sanitation.

Plants listen more closely to kin than strangers

It is not just humans that like a natter with their nearest and dearest – plants pay most attention to their closest relatives.

When an insect bites a leaf, many plants release volatile chemicals to prime their neighbours for attack. The defences this triggers vary – some plants respond by attracting predatory insects that eat the herbivores, others make themselves less tasty.

Now Richard Karban of the University of California, Davis, has shown that for the sagebrush, responses to these warning signals can vary with relatedness.

At the start of three growing seasons, Karban's team exposed different branches of the same plants to volatile chemicals. The substances came from relatives of the same species whose leaves had been clipped to trigger chemical release.

By the end of the seasons, herbivores had done less damage to the branches exposed to chemicals from close relatives than to those receiving signals from more distant relatives – the warning probably prompting the plants to release herbivore-deterring chemicals, says Karban.

He has previously shown that the blend of volatiles varies enormously between individuals – "so much so that big peaks in some individuals are undetectable in others", he says.

However, there is some similarity between family members. Karban thinks this variability is being exploited by the plants as a kind of family-specific signature, to prevent eavesdroppers from listening in and to give those that share the same genes a greater chance of survival.

Some plants are genetically more resistant to being eaten than others, so it makes sense that plants should care more about their kin's fate than that of the general population.

"It is very elegant work," says Susan Dudley from McMaster University in Ontario, Canada, who has shown that plants competing for space in a small pot are less aggressive if they are related to their neighbours.

She thinks this kind of kin-recognition is probably common among many plants.

Peru archeologists find ancient temple

LIMA: Peruvian archaeologists have discovered a temple believed to be about 5,000 years old at the ancient archaeological site of El Paraiso in a valley just north of Lima, the Culture Ministry said Tuesday.

If the date is confirmed, it would be among the oldest sites in the world, comparable to the ancient city of Caral, a coastal city some 200 kilometres (125 miles) to the north.

The discovery, dubbed the Temple of Fire, was found in one of the wings of El Paraiso's main pyramid. It includes a hearth that experts believe was used to burn ceremonial offerings.

"The smoke allowed the priests to connect with the gods," said Marco Guillen, who led the team of researchers who made the find.

Archaeologists found the hearth in mid-January as they were carrying out conservation work at a set of 4,000-year-old ruins known as El Paraiso, located some 40 kilometers northeast of Lima in the Chillon River Valley.

The discovery shows "that the Lima region was a focus of civilizations in the Andean territory," Deputy Culture Minister Rafael Varon told reporters.

Archaeologists believe the ancient coastal civilisations raised crops including cotton, which they traded with coastal fishermen for food.

El Paraiso, spread across 50 hectares (125 acres), has 10 buildings and is one of the largest ancient sites in central Peru.

Tip: Use OS X services to reveal or open file paths

Apple's Spotlight offers a quick way to find user files and resources like applications or system preferences. However, it does not locate items in the system folder or in hidden folders, though at times you might need to access them. This limitation may be especially cumbersome to deal with if you are troubleshooting a problem in OS X or helping someone do so, meaning you may need to ask them to locate a specific hidden file and remove it or modify its contents.

For some system resources you can simply navigate through the Finder; however, in its default view the Finder does not show a number of hidden files and folders such as the user library. So, for example, if you tell someone to access his or her user library to locate the Fonts folder, since the user library is hidden he or she might instead erroneously access the global library at the root of the hard drive.

Right-clicking a selected text path will show an option in the Services menu to open or reveal the path in the Finder.

Even if you are familiar with standard Unix file path notation and direct someone to open the ~/Library folder, if that person doesn't know what the tilde character means then he or she might go to the wrong directory in the Finder.

To get around these potential areas of confusion both for yourself and when instructing others, you can make use of some services and features in OS X that make possible quick access to any file or folder based on a typed path you provide, which can help avoid confusion and make it straightforward for anyone to open a specified Unix-compliant path.

The first option is to use the system's contextual services: if you have a full Unix-compliant path typed out, then you can simply highlight it, right-click the selected text, and then choose either Open or Reveal from the Services contextual menu, and the system will then display the item in the Finder or try to open it with its default handling application.

For example, you can triple-click the following folder path examples or otherwise select each in its entirety, and try opening the items in the Finder (note that if you use the Open service the system may ask for confirmation before opening the path):

This warning may show up if you use the Open service.

~/Library/Fonts

/System/Library/CoreServices

/var/db/dslocal/nodes

/Volumes

If you come across a file path as part of an instruction for tweaking your system or troubleshooting it, you can use these services to access it by selecting the file path and right-clicking in this way. Additionally, if you are attempting to help others access parts of their systems and you know the exact file or folder path they should use, then you can likewise send it to them and have them perform this procedure to quickly open it.

These services can be enabled or disabled in the Keyboard system preferences. You can also assign them custom hot keys if desired.

(Credit:
Screenshot by Topher Kessler/CNET)

These contextual services are built into OS X and should be enabled by default, but if they aren't then they can be enabled in the Services section of the Keyboard system preferences, under the Keyboard Shortcuts tab.

While useful for opening a full file path from a text document or Web page, these options are also convenient in other areas. If you are a power user and access the Terminal regularly, then you probably have a number of file paths listed in your command history that you previously acted upon. If you need to open one of these paths in the Finder, you can use these services to quickly select and open it.

A last and related way to navigate through a full file path is to use the OS X Go to Folder feature that is available in the Finder's Go menu (and can also be invoked by pressing Shift-Command-G). With this option, you can copy a full file path or even a partial one with respect to the directory of the current Finder window, and then paste it in the Go to Folder field instead of using the Open or Reveal services, which should open it for you in the Finder. For example, select and copy any of the file paths listed above, and then paste it in the Go to Folder field to have the system open it in the Finder.
