Swimming: Trickett urges healing after "toxic" Games

SYDNEY: Australian swimmer Libby Trickett called for healing within the sport after reports exposed a "toxic" atmosphere at the London Olympics including drunkenness, deceit and bullying.

Swimming Australia has vowed to restore its standing with the public after the country's much vaunted swimmers disappointed at the 2012 Olympics and inquiries into its culture revealed discipline was loose and the squad lacked leadership.

Trickett, who has won four gold medals at three Olympics, welcomed the news that officials would further investigate allegations against the team, including that some athletes misused prescription drugs as a prank in London.

"That issue has been left unresolved and it needs to be dealt with in order for us to move on," she told the Australian newspaper.

"It probably has gone too long without being dealt with. It certainly does need to be addressed because... if we let this one go, it's a precedent for the future."

She said all swimmers had been "under a cloud" because no individuals had so far been named.

"But if names are named, we will need to support them through the difficult times that lie ahead for them -- and they will be difficult," she said, The Australian reported.

"We need to come together again as a team and what better way to do that than by embracing these swimmers?"

Australia endured its worst swimming haul in decades in London, winning just one gold medal, six silver and three bronze for its lowest tally in the pool since Barcelona in 1992.

The lacklustre performance, in which no individual swimming gold medal was won for the first time since the 1976 Montreal Games, resulted in the commissioning of two independent reports released on Tuesday.

They revealed that morale within the swimming team was so low one athlete referred to London as the "lonely Olympics" as individuals looked after themselves ahead of the team.

Higgs Boson calculations add up to new Armageddon scenario

Anyone who thinks the end is nigh with a giant asteroid colliding into Earth may have a new apocalypse scenario to worry about.

It all boils down to the Higgs Boson particle, aka the "God particle."

Calculations that came with the likely discovery of the Higgs Boson last July also show that the particle's mass qualities could spell out the end of the universe said Fermilab theoretical physicist Joseph Lykken yesterday, according to NBC's Cosmic Log.

However, doomsdayers don't need to fret too much, the scientist also said that the likelihood of such a demise is probably tens of billions of years off.

The God particle was likely discovered last year when scientists at the CERN nuclear research facility observed a particle consistent with the Higgs running through the Large Hadron Collider. Until then, the particle was a theoretical idea rather than a sure thing. Higgs is thought to be responsible for mass in the otherwise-already-proven standard model of physics.

Theory on the particle indicates that mass can be transmitted to other fundamental particles in the universe, which is how the possibility of the end of the world comes into play. This idea of mass transference suggests that the universe is not completely stable -- it's actually in a "metastable" state.

"If you use all the physics that we know now, and we do what we think is a straightforward calculation, it's bad news," Lykken said, according to NBC. "The universe wants to be in a different state, so eventually to realize that, a little bubble of what you might think of as an alternate universe will appear somewhere, and it will spread out and destroy us."

Basically, Lykken says that our universe could easily be slapped out by another universe. However, he also said that if it does happen, it will happen at the speed of light -- which means it will be so fast we won't even realize it.

Florida Python Hunt Captures 68 Invasive Snakes

It's a wrap—the 2013 Python Challenge has nabbed 68 invasive Burmese pythons in Florida, organizers say. And experts are surprised so many of the elusive giants were caught.

Nearly 1,600 people from 38 states—most of them inexperienced hunters—registered for the chance to track down one of the animals, many of which descend from snakes that either escaped or were dumped into the wild.

Since being introduced, these Asian behemoths have flourished in Florida's swamps while also squeezing out local populations of the state's native mammals, especially in the Everglades. (See Everglades pictures.)

To highlight the python problem, the Florida Fish and Wildlife Conservation Commission and its partners launched the 2013 Python Challenge, which encouraged registered participants to catch as many pythons as they could between January 12 and February 10 in state wildlife-management areas within the Everglades.

The commission gave cash prizes to those who harvested the most and longest pythons.

Frank Mazzotti, a wildlife ecologist at the University of Florida and scientific leader for the challenge, said before the hunt that he would consider a harvest of 70 animals a success—and 68 is close enough to say the event met its goals.

It's unknown just how many Burmese pythons live in Florida, but catching 68 snakes is an "exceptional" number, added Kenneth Krysko, senior herpetologist at the Florida Museum of Natural History in Gainesville.

Snakes in the Grass

Finding 68 snakes is impressive, experts say, since it's so hard to find pythons. For one, it's been unusually warm lately in Florida, which means the reptiles—which normally sun themselves to regulate their body temperature—are staying in the brush, making them harder to detect, Krysko said.

On top of that, Burmese pythons are notoriously hard to locate, experts say.

The animals are so well camouflaged that people can stand right next to one and not notice it. "It's rare that you get to see them stretched out—most of the time they're blending in," said Cheryl Millett, a biologist at the Nature Conservancy, a Python Challenge partner.

What's more, the reptiles are ambush hunters, which means they spend much of their time lying in wait in dense vegetation, not moving, she said.

That's why Millett gave the hunters some tips, such as looking along the water's edge, where the snakes like to hang out, and also simply listening for "something big moving through the vegetation."

Even so, catching 68 snakes is "actually is a little more than I expected," said Millett.

No Walk in the Park

Ruben Ramirez, founder of the company Florida Python Hunters, won two prizes in the competition: First place for the most snakes captured—18—and second place for the largest python, which he said was close to 11 feet (3.4 meters) long. The biggest Burmese python caught in Florida, nabbed in 2012, measured 17.7 feet (5.4 meters).

"They're there, but they're not as easy to find as people think," said Ramirez. "You're not going to be stumbling over pythons in Miami." (Related blog post: "What It's Like to Be a Florida Python Hunter.")

All participants, some of whom had never hunted a python before, were trained to identify the difference between a Burmese python and Florida's native snakes, said Millett. No native snakes were accidentally killed, she said.

Hunters were also told to kill the snakes by either putting a bolt or a bullet through their heads, or decapitating them-all humane methods that result "in immediate loss of consciousness and destruction of the brain," according to the Python Challenge website.

Ramirez added that some of the first-time or amateur hunters had different expectations. "I think they were expecting to walk down a canal and see a 10-foot [3-meter], 15-foot [4.5-meter] Burmese python. They thought it'd be a walk in the park."

Stopping the Spread

Completely removing these snakes from the wild isn't easy, and some scientists see the Python Challenge as helping to achieve part of that goal. (Read an opposing view on the Python Challenge: "Opinion: Florida's Great Snake Hunt Is a Cheap Stunt.")

"You're talking about 68 more animals removed from the population that shouldn't be there—that's 68 more mouths that aren't being fed," said the Florida museum's Krysko. (Read about giant Burmese python meals that went bust.)

"I support any kind of event or program that not only informs the general public about introduced species, but also gets the public involved in removing these nonnative animals that don't belong there."

The Nature Conservancy's Millett said the challenge had two positive outcomes: boosting knowledge for both science and the public.

People who didn't want to hunt or touch the snakes could still help, she said, by reporting sightings of exotic species to 888-IVE-GOT-1, through free IveGot1 apps, or www.ivegot1.org.

Millett runs a public-private Nature Conservancy partnership called Python Patrol that the Florida wildlife commission will take on in the fall. The program focuses not only on eradicating invasive pythons but on preventing the snake from moving to ecologically sensitive areas, such as Key West.

Necropsies on the captured snakes will reveal what pythons are eating, and location data from the hunters will help scientists figure out where the snakes are living—valuable data for researchers working to stop their spread.

"This is the most [number of] pythons that have been caught in this short of a period of time in such an extensive area," said the University of Florida's Mazzotti.

"It's an unprecedented sample, and we're going to get a lot of information out of that."

Former Navy SEAL on Coming Out of Shadows

It used to be that Navy SEALs didn't just operate in the shadows. They trained in them too. Their whole story stayed shrouded in mystery. Their secret missions stayed secret to the rest of us.

But when they got Osama Bin Laden, snatched back an American cargo ship taken by pirates and rescued two air workers held hostage in Somalia, then suddenly, it seemed that SEALs were headline-makers.

Add to that some SEALs wrote books about SEAL adventures and even acted in a movie about the SEAL experience using live ammunition when they made "Act of Valor." They can't quite be called "the military unit that no one ever talked about" any longer.

Watch the full story on "Nightline" TONIGHT at 12:35 a.m. ET

Rorke Denver played Lt. Commander Rorke in "Act of Valor," a film that used dozens of SEALs and went on to gross $80 million at the box office. Now, with the help of a writer, Denver is doing some pretty decent storytelling in a new book, "Damn Few: Making the Modern SEAL Warrior."

He agrees that with SEALs like him telling their stories that these guys are out in the open like never before.

"We are, at this moment in our history, when the heat is on, the missions are getting press and coverage," Denver said.

When asked if it was a good thing, he said, "time will tell."

"We are in the public eye and I think that mythology is something that people are hugely, hugely interested in and they have an appetite for it," Denver said. "So for us with the movie and then also with 'Damn Few' I had an opportunity, I feel, to authentically represent and hopefully do it from an honorable point of view and accurately do so."

It's mostly his own story Denver tells in "Damn Few," how he joined the SEALs after college -- they didn't want him at first.

"I put in my first application and they said no, and I am glad it went that way. I think the community really values resiliency and toughness and focus and a 'never quit' attitude. For me, when they said no I thought, that ain't going to cut it."

Denver didn't quit. He reapplied and went on to survive the SEALs brutal Hell Week and training, joined the team and deployed all over the world, including the deadly Al Anbar province in Iraq when the war there was at its hottest. His family waited for him to return stateside.

"The families, I feel, are the ones who pay the price of our choices," Denver said. "But I didn't appreciate how much I was asking my family to bear and experience it with me. They really are every bit a part of our experience and frankly they are the ones who are back home and praying and believing that you are going to come home."

But even his family didn't quite know what Denver did at work every day.

"I never ask questions about what he does," said his wife, Tracy.

But "Act of Valor" was revealing in that way, and Denver's wife watched the film.

"For me it was incredibly eye-opening to actually see a submarine mission or running around in the jungle, jumping out of a plane, shooting his weapons," she said. "For me, it was like, oh, so this is what you are doing when you are away. I appreciated it actually."

Biofuel rush is wiping out unique American grasslands

Say goodbye to the grass. The scramble for biofuels is rapidly killing off unique grasslands and pastures in the central US.

Christopher Wright and Michael Wimberly of South Dakota State University in Brookings analysed satellite images of five states in the western corn belt. They found that 530,000 hectares of grassland disappeared under blankets of maize and soya beans between 2006 and 2011. The rate was fastest in South Dakota and Iowa, with as much as 5 per cent of pasture becoming cropland each year.

The trend is being driven by rising demand for the crops, partly through incentives to use them as fuels instead of food.

The switch from meadows to crops is causing a crash in populations of ground-nesting birds. One of the US's most important breeding grounds for wildfowl, an area called the Prairie Pothole Region, is also at risk, with South Dakota's crop fields now within 100 metres of the wetlands. "Half of North American ducks breed here," says Wright.

Bill Henwood of the Temperate Grasslands Conservation Initiative in Vancouver, Canada, says the results are distressing. "Exchanging real environmental impacts for the dubious benefits of biofuels is counterproductive," he says. "Last year's record drought in the corn belt all but wiped out the crops anyway."

S'pore, Malaysia agree on high-speed rail link

SINGAPORE: Singapore and Malaysia have agreed to build a high-speed rail link between Kuala Lumpur and Singapore, with a target to complete it by 2020.

This was announced by Prime Minister Lee Hsien Loong and Malaysian Prime Minister Najib Razak on Tuesday during their annual Leaders' Retreat.

With the new link, it will take about 90 minutes to get from Singapore to KL and vice versa.

The two leaders described the high-speed rail system as a strategic development in the bilateral relations, saying it will dramatically improve the connectivity between Malaysia and Singapore.

Mr Lee said: "It is a strategic project for the two countries. It will change the way we see each other. It is the way people in London and Paris are able to think of it -- as twin cities, where you can commute, go up there, do business, meet friends, have a meal and come back, all within two thirds of the day.

"And I think it is going to be a game changer. It will transform the way people interact, the intensity of our cooperation and the degree to which we become interdependent on each other and therefore have stakes on each other's success."

The leaders added that it will usher in a new era of strong growth, prosperity and opportunities for both countries.

The link will also facilitate seamless travel between KL and Singapore, enhance business links, and bring peoples of Singapore and Malaysia closer together.

The leaders added that ultimately the project will give both countries greater stakes in each other's prosperity and success.

Mr Najib said: "Our two cities will complement each other. Our two countries will look at each other differently and the opportunities are boundless between our two countries.

"So I am excited about the project. We will certainly do our level best to meet the 2020 deadline. It may go slightly beyond that, but those are details in implementation."

The prime ministers have tasked a joint ministerial committee to look into the details and modalities of the high-speed rail link.

"The modalities will be offered to Singapore. Basically, we want Singapore to participate in this based on the different kinds of options that we will offer to the Singapore government," added Mr Najib.

Microsoft moves Outlook.com out of preview

Microsoft announced Tuesday that its Outlook.com browser-based e-mail service has moved out of its preview stage and is now available globally.

First introduced last July, Outlook.com is Microsoft's boldest e-mail move since Google launched Gmail in 2004 and a clear answer to it. As I said in my First Take, the simple interface, Skydrive integration, and promise of mega storage will remind you of Google's product while the People Hub and vaguely Windows 8 look and feel give Outlook.com a distinct identity.

Microsoft designed Outlook.com to replace its Hotmail product, which it acquired in 1997, and the general availability marks the start of that process. The Hotmail name won't disappear entirely, but Outlook.com will become Microsoft's sole free consumer e-mail offering.

In a phone interview last week, Senior Director of Product Management Dharmesh Mehta said existing Hotmail users can switch over at anytime. You'll be able to keep using your "@Hotmail" address and you'll have the option to claim an "@Outlook.com" alias, as well.

Users who don't switch over on their own will be upgraded in waves to the new product automatically starting this week. Mehta said that the process should finish by the summer, though he declined to name an exact date.

Microsoft also announced that in the six months since Outlook.com debut, the service has attracted to 60 million users. And in an effort to attract more, Mehta said that the company is launching its largest marketing ever for an e-mail service.

Outlook.com's minimalist interface is both familiar and unique.

Confirmed: Dogs Sneak Food When People Aren't Looking

Many dog owners will swear their pups are up to something when out of view of watchful eyes. Shoes go missing, couches have mysterious teeth marks, and food disappears. They seem to disregard the word "no."

Now, a new study suggests dogs might understand people even better than we thought. (Related: "Animal Minds.")

The research shows that domestic dogs, when told not to snatch a piece of food, are more likely to disobey the command in a dark room than in a lit room.

This suggests that man's best friend is capable of understanding a human's point of view, said study leader Juliane Kaminski, a psychologist at the U.K.'s University of Portmouth.

"The one thing we can say is that dogs really have specialized skills in reading human communication," she said. "This is special in dogs." (Read "How to Build a Dog.")

Sneaky Canines

Kaminski and colleagues recruited 84 dogs, all of which were more than a year old, motivated by food, and comfortable with both strangers and dark rooms.

The team then set up experiments in which a person commanded a dog not to take a piece of food on the floor and repeated the commands in a room with different lighting scenarios ranging from fully lit to fully dark.

They found that the dogs were four times as likely to steal the food—and steal it more quickly—when the room was dark. (Take our dog quiz.)

"We were thinking what affected the dog was whether they saw the human, but seeing the human or not didn't affect the behavior," said Kaminski, whose study was published recently in the journal Animal Cognition.

Instead, she said, the dog's behavior depended on whether the food was in the light or not, suggesting that the dog made its decision based on whether the human could see them approaching the food.

"In a general sense, [Kaminski] and other researchers are interested in whether the dog has a theory of mind," said Alexandra Horowitz, head of the Dog Cognition Lab at Barnard University, who was not involved in the new study.

Something that all normal adult humans have, theory of mind is "an understanding that others have different perspective, knowledge, feelings than we do," said Horowitz, also the author of Inside of a Dog.

Smarter Than We Think

While research has previously been focused on our closer relatives—chimpanzees and bonobos—interest in dog cognition is increasing, thanks in part to owners wanting to know what their dogs are thinking. (Pictures: How smart are these animals?)

"The study of dog cognition suddenly began about 15 years ago," Horowitz said.

Part of the reason for that, said Brian Hare, director of the Duke Canine Cognition Lab and author of The Genius of Dogs, is that "science thought dogs were unremarkable."

But "dogs have a genius—years ago we didn't know what that was," said Hare, who was not involved in the new research. (See pictures of the the evolution of dogs, from wolf to woof.)

Many of the new dog studies are variations on research done with chimpanzees, bonobos, and even young children. Animal-cognition researchers are looking into dogs' ability to imitate, solve problems, or navigate social environments.

So just how much does your dog understand? It's much more than you—and science—probably thought.

Selectively bred as companions for thousands of years, dogs are especially attuned to human emotions—and, study leader Kaminski said, are better at reading human cues than even our closest mammalian relatives.

"There has been a physiological change in dogs because of domestication," Duke's Hare added. "Dogs want to bond with us in ways other species don't." (Related: "Dogs' Brains Reorganized by Breeding.")

While research reveals more and more insight into the minds of our furry best friends, Kaminski said, "We still don't know just how smart they are."

Obama's Speech on Guns Doesn't Stop Ill. Killing

A Chicago teenager was shot and killed Friday only hours after her sister attended President Obama's speech on the city's rampant gun violence.
Janay McFarlane, 18, was killed while walking with a friend during a visit to her dad, Herbert McFarlane, in North Chicago.

"All this gun violence going on, you never think it would be your child," he told ABC's Chicago station WLS. "This is the hardest thing for me in my life."

Herbert McFarlane told WLS that the loss of Janay is especially hard because she leaves behind a 3-month old son, who likes to wear an "I love Mommy" shirt. The shooting occurred in Lake County, a northern suburb miles from the epicenter of the gun violence on the city's South Side.

"I'm in Lake County to get away from violence and now it happened in Lake County where I moved to," he told WLS.

McFarlane and her child spent time both in Lake County and on the South Side where her mother lives.

Only hours before McFarlane was shot and killed, President Obama returned to his hometown to speak on the South Side at a Hyde Park high school. McFarlane's sister, Destini Warren, 14, sat behind the president during the speech.

More than 500 people were shot and killed here last year, and this year the situation has worsened with the most deadly January the city has seen in over a decade. The shooting death of Hadiya Pendleton, a 15-year old who performed in Washington, D.C. at events connected to the president's inauguration last month, garnered national attention.

"Too many of our children are being taken away from us," Obama said in Hyde Park, with McFarlane's sister in the audience.

"Last year there were 443 murders with a firearm on the streets of this city, and 65 of those victims were 18 and under," he said. "So that's the equivalent of a Newtown every four months." He was referring to Newtown, Conn., where 20 first graders were gunned down by Adam Lanza along with seven adults.

Only hours later in Chicago, another 18-year old was shot and killed.

"I felt like someone took a knife and stabbed me in the heart, and a piece of my heart I will never get back," Angela Blakely, Janay McFarlane's mother, told WLS.

North Chicago Police on Sunday reportedly questioned two people in connection to McFarlane's death. Her family said McFarlane was an unintended target of the shooting.

Messages left by ABC News with the North Chicago Police Department and the Lake County Coroner's Office went unreturned Monday.

Another Chicago teenager, Frances Colon, was also shot and killed Friday just hours after she had told her father that she saw President Obama's helicopter fly over her neighborhood.

Wiping out top predators messes up the climate

Wiping out top predators like lions, wolves and sharks is tragic, bad for ecosystems – and can make climate change worse. Mass extinctions of the big beasts of the jungles, grasslands and oceans could already be adding to greenhouse gases in the atmosphere.

Trisha Atwood of the University of British Columbia in Vancouver, Canada, studied the effect of removing predator fish from ponds and rivers in Canada and Costa Rica. Across a range of ecosystems, climates and predators, she found a consistent pattern: carbon dioxide emissions typically increased more than tenfold after the predators were removed.

"It looks like predators in many types of ecosystems – marine and terrestrial as well as freshwater – can play a very big role in global climate change," she told New Scientist.

The widespread and dramatic ecological impacts of the loss of top predators are well known. In the ensuing "trophic cascade", the vanished top predator's prey proliferate, which in turn puts pressure on the species that the prey eats, and so on down the food chain. In this way, changes at the top of a food chain destabilise the balance of populations right the way down.

But the geochemical impacts of trophic cascades, including any impact on emissions from ecosystems, are much less well known. Atwood's study of freshwater ecosystems showed how changes to species at the bottom of the food chain, such as photosynthesising algae, following the removal of a top predator dramatically increased the flow of CO₂ from the ecosystem to the atmosphere.

The effect will not always be to increase CO₂ emissions, however – sometimes the loss of top predators could decrease emissions, she says. "But we show that something so seemingly unrelated, like fishing all the trout from a pond or removing sharks from the ocean, could have big consequences for greenhouse-gas dynamics."

Help from kelp

Other recent studies have hinted at similar effects. Last October, Christopher Wilmers of the University of California, Santa Cruz, reported how the disappearance of sea otters is linked with increased CO₂ emissions from North American coastlines (Frontiers in Ecology and the Environment, doi.org/khz). With no otters eating them, sea urchins thrive and eat out kelp forests – often known as the "rainforests of the oceans" – resulting in major CO₂ releases.

Global climate models do not take such impacts into account yet. Atwood says they could be major, as freshwater emissions may be on a par with the influence of deforestation, which is thought responsible for around 15 per cent of human-caused CO₂ emissions.

Environmentalists will herald the findings as further evidence that it is vital to protect pristine habitats and the charismatic species at the top of their food chains. But there is a dark side. A recent study found that some island ecosystems around New Zealand store 40 per cent more carbon than others because of their top predators – invading rats that are wiping out seabird colonies. Rats, it seems, are good for the climate (Biology Letters, doi.org/bbmtw9).
