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).

Basketball: West wins third in a row over East in All-Star Game

HOUSTON, Texas: Chris Paul scored 20 points and passed out 15 assists to spark the Western Conference over the Eastern Conference 143-138 in the 62nd NBA All-Star Game.

NBA scoring leader Kevin Durant had a game-high 30 points for the West and Paul's Los Angeles Clippers teammate Blake Griffin added 19 points, both of them jamming down spectacular slam dunks thanks to set-up passes from Paul.

Clippers guard Paul was voted the NBA All-Star Game's Most Valuable Player as the West won the annual showdown of elite hoops talent for the third time in a row and fourth time in five games.

"You just never expect something like this," Paul said. "All these great players I have the chance to play with, it's an honour and a privilege."

Paul joined Magic Johnson and Isiah Thomas as the only All-Star Game players to produce at least 20 points and 15 assists in one game.

"To be mentioned with those guys, it's an honour," Paul said. "To be on the court with all these guys I don't get the chance to play with, it's an privilege."

Carmelo Anthony led the East with 26 points and 12 rebounds while LeBron James added 19 points and Paul George contributed 17.

The West led 69-65 at half-time and had the same margin, 108-104, entering the fourth quarter when a showy game of dunks and flashy moves found intensity.

Back-to-back 3-pointers by Kyrie Irving pulled the East within 119-118, but Durant had two slam dunks in an 8-2 West run to boost the lead to 127-120.

Anthony sparked a 6-2 East run to pull his side within 129-126 but Paul followed with a 3-pointer and Kobe Bryant played tight defence on James in what became a man-on-man rivalry between playmakers in the final minutes.

Bryant made a driving layup and blocked a James shot to set up a fast break slam dunk by Durant to put the West ahead 136-126. Bryant later added another block of James as the two traded taunts on the court.

Durant became the first player to score at least 30 points in three consecutive NBA All-Star Games.

Paul answered an East basket with his fourth 3-pointer of the game and after George hit back-to-back 3-pointers, Griffin answered with a free throw and a fast break slam dunk that included a pass to himself off the backboard.

Spectacular slam dunks by James, Durant and Griffin produced the most sparkling moments of the first half.

Dwyane Wade set up Miami teammate James for the East but made one of his best passes to Tyson Chandler for a running one-handed alley-oop jam while Bryant and Paul kept Durant and Griffin set up for dunks.

"If they run, I have fun just assisting and passing the ball," Paul said.

Durant made 8-of-12 shots for 19 points in the first half while every basket by Griffin in the first half came on a slam dunk.

Big men Dwight Howard and Tim Duncan tried to see who could sink a rare 3-pointer first while guards took turns dribbling between the legs of rivals as the players used the light-hearted matchup for fun moments that regular NBA games rarely allow.

"You need a three, give it to me," West center Howard said.

Before the game, played on the 50th birthday of NBA legend Michael Jordan, James -- a modern-day displayer of Jordan's gravity-defying, high-leaping moves -- tweeted his best wishes to six-time NBA champion Jordan.

"Happy 50th MJ! U inspired a kid from Akron Ohio without u even knowing," James tweeted. "All by just playing the game u loved. I appreciate what u did for the game and don't take it for granted."

James ended the messages with the hashtag GOAT for Greatest of All Time.

Why Google's stores shouldn't look so much like Apple stores

Is this really different enough?

(Credit:
Crave CNET UK)

Some engineers have never dated a real person.

They've tried to, but it's hard for them to appreciate that real people don't necessarily use data to make decisions -- especially when it comes to love.

Perhaps their most embarrassing moments come when they try to mimic what non-engineers do in order to make themselves more attractive.

This mirrors some of the little issues that the Google brand has had over the years in becoming, well, human.

When you've spent you life believing that facts are everything, it's hard to imagine that people might prefer, oh, rounded corners or that ephemeral thing sometimes known as taste.

Google has made progress through some of its advertising. The "Jess Time" ad for Chrome was one of the very best tech ads of the 2012.

Yet when Google has wandered into retail, it has either believed that all you need is online or that an offline store ought to look rather like Apple's.

This is something against which Microsoft also struggles. It was almost comical when one Microsoft employee explained to me that its store looked -- at first glance -- a lot like the Apple store because the company used the same design firm.

This week, rumors surfaced that Google wants to make the next step in coming toward humanity by having its own shopping-mall retail presence.

The evidence so far from its pop-up stores -- as the picture above shows -- is that Google isn't thinking different. Or, at least, different enough.

If it fully intends to come out to the people -- to be itself-- then instead of having nice, clean retail staff in blue T-shirts (what brand does that remind you of?), it should embrace its true heart.

It should have real house-trained nerds, replete with bedhead and bad taste clothing, there for all to see. Yes, you could have nice, normal members of staff there to translate for them.

But the purpose of a retail store isn't merely to sell. It's to create street theater. Apple has its own version. Google must find its own too.

Instead of the now almost cliched clean lines and permanent white, it should make its stores look like excitable, sophisticated college playrooms, where books about dragons and vast Hulk hands are lying about and episodes of "Star Trek" and "Game of Thrones" are playing on huge screens.

More Technically Incorrect

It should expose itself fully as a brand that came out of nerdomania by parading its nerdomanic tendencies for all to see and making it lovable.

You might think this marginally insane. You might think that I am suffering from delusions of brandy.

Yet "The Big Bang Theory" has proved to be one of the most popular TV shows, not because the nerds are hidden away, but because they are in full view, with a beautiful counterpoint in a real person called Penny.

Imagine taking your kids, your lover, or your granny into a Google store and having them actually enjoy learning something about, say, comic books or Hermann von Helmholtz.

Imagine walking in and one of the Google nerds has dressed as The Flash, Batman, or Wonder Woman for the day, yet still finds a way to sell you a fascinating
Nexus 7.

In fact, wouldn't it be an excellent human resources idea, as well as a stimulus to make more uplifting products, if every Google engineer had to spend a certain period working in a Google retail store?

Mountain View should surely mine the more lofty, fantastic elements of its reality in order to create something unique and dramatic.

Otherwise, its stores might simply be accused of being Apple rip-offs.

And you know where that will ultimately end up. Yes, in front of Judge Lucy Koh.

Meet the Meteorite Hunter

Michael Farmer is one of the world's only full-time meteorite hunters. Since the 1990s, the 40-year-old Tucson, Arizona, resident has been scouring the world for pieces of interstellar rock, racing to be the first one on the scene and selling his finds to museums and private collectors. On Friday, as Russians reportedly scrambled to collect fragments from a passing meteorite that injured hundreds, Farmer spoke with National Geographic about his unusual line of work.

Why are so many people in Russia busy gathering up meteorite fragments?

It's a historic event. This will be talked about forever. Everyone wants to have a little piece of it. And scientifically, we want to study it. We want to know what's out there, and we want to know how big it is, and we want to know what damage it can cause. The preliminary data from NASA's Jet Propulsion Laboratory says about 7,000 tons landed.

How many meteorite fragments are known to be on Earth?

There are a couple of hundred thousand known meteorites. Of course, there's millions and millions on the planet; we just have to find them. Most of the Earth is inhospitable—heavy forest, jungle, ocean. Meteorites that fall in the ocean are just gone, disappeared to the bottom.

How many other full-time meteorite hunters are there?

Dedicated, serious meteorite hunters? There are maybe 20 of us. If you add in the part-timers who go somewhere whenever [an impact is] close to them, then you might approach a hundred.

How did you become a meteorite hunter?

Here in Tucson right now we have the world's biggest mineral show going on. I bought a meteorite at this very same show 20 years ago, and I was absolutely obsessed and hooked. Since then I've been around the world more times than I can count—four million miles on American Airlines alone.

How many countries have you been to?

About 70 countries, by my last count. About 50, 59 trips to Africa—a lot of work in Africa. The Sahara and other deserts there make meteorites easier to find than on other terrains, and also keep them well preserved.

What are the challenges you face when you're on a hunt?

Well, you're usually going into a kind of chaotic scene where nobody really knows much. In Africa and other places I go [the locals] don't usually understand what's happening, and most of the time they don't care. They're more concerned with eating that day. But the instant some guy shows up and says, "I'll pay you to find this rock," the whole village empties—and then lots of rocks show up.

It can be dangerous work. I've been robbed, put into prison. For example, I was in prison two years ago in the Middle East, in Oman—actually sentenced, convicted, and put in prison for three months for "illegal mining activity." Not a very nice time. And the same year, 2011, in the fall I went to Kenya three times, after a major meteorite fell. On the third trip over I had a robbery where they ambushed us and almost murdered me. I was down on my knees, with a bag over my head and a machete on my throat and a gun at my head, being beaten. Luckily they decided to just take everything and leave instead of killing us. It's a dangerous line of work because it involves money, and people want that money.

What's the most valuable meteorite you've found?

Well, I've found three separate moon rocks in the Middle East. [Moon rocks are considered a type of meteorite that came loose from the lunar surface and fell to Earth.] And one of them I sold for $100,000 a week later. It was just a small piece—the size of a walnut. But the best meteorite I found was with my three partners up in Canada. It was actually discovered in 1931, but we went back to the location and discovered 53 kilograms [117 pounds] more. It's an extremely rare type of meteorite called a pallasite, and it's about 4.5 billion years old. We sold it to the Canadian government for just under a million dollars. Now it's in the Royal Ontario Museum, in Toronto, and it's considered a national treasure.

Where else do you sell your wares?

Well, I do shows around the world, in France, Germany, Japan. I go to expos, like this one here in Tucson, which is the biggest mineral show in the world and lasts for three weeks. And museums are always calling me.

Related: Archival Photos of Meteorite Recovery

It's a small market. It's not like I need a shop or anything. People call me or email me or go to my website and check it out. The market these days is so ravenous for anything new that when I get a new meteorite, it's usually sold in hours. I don't even have to work anymore. I just make phone calls to a few people, and it's all gone.

Where do you store your collection?

I have multiple storage sites—never put all your eggs in one basket. And I have lots of bulk material. Sometimes I buy this stuff by the ton, and it goes into storage and I sell it off one piece at a time.

What's the verification process like?

Any meteorite, anything that we want to have an official name, has to go to a laboratory, where it gets sectioned and studied by scientists. For example, I'd guess this meteorite in Russia yesterday will be in a lab in Moscow, being researched within hours.

Related: History's Big Meteorite Crashes

In the collector market, we work collaboratively with the scientists. I supply them with rocks, and they supply me with data, both of which I need to make money. People want to know what something is before they buy it.

Are there legal or ethical implications to meteorite hunting?

There always are. Certain countries have passed laws. But when I was arrested in Oman, they actually had no law—they were just very upset that we were taking lots of meteorites. The only law they could charge us with was illegal mining operations—basically running a company in the country without government licensing. But I won on appeal because we had no mining equipment. We were picking up rocks off the surface of the desert. And a judge said, "If a child could do it, then it's not mining." And I was immediately released and sent home.

But there's always friction between the collecting market and the scientific market. There are scientists out there who believe that no meteorite should be in private hands. Well, I tell you, I've been on hunts all over the world and I've only run into scientists a couple of times. They don't have the time or money to do it. So if it wasn't for us, 99 percent of these meteorites would be lost to science.

What about this meteorite strike—do you think scientists will go to Russia?

I guarantee there'll be scientists from everywhere in the world going to this one.

Are you catching the next flight to Moscow?

Well, of course as a meteorite dealer, I want to own this. I woke up this morning to a hundred e-mails from people begging me to get on a plane and go get it so they can buy a piece.

But I'm probably not going. Getting into Russia can be complicated. I'll just buy some from the Russians when it comes out.

Of course, if this had happened in China or somewhere in Africa, I'd be packing my bags right now and getting on a plane, figuring it all out when I get there.

Troubled Country Singer Shot Herself, Cops Say

Mindy McCready, the country singer who soared to the top of the charts with her debut album, "Ten Thousand Angels," but struggled with substance abuse, served time in jail and fought a lengthy battle with her mother over custody of her son has died of what appears to be a self-inflicted gunshot wound, police said. She was 37.

Deputies from the Cleburne County Sheriff's Office were dispatched to a report of gun shots fired at McCready's Heber Springs, Ark., home at around 3:30 p.m. today.

There they found McCready on the front porch. She was pronounced dead at the scene from what appeared to be a single self-inflicted gunshot wound, according to a statement from the sheriff's office.

McCready's boyfriend, David Wilson, died in January of a self-inflicted gunshot wound. McCready was ordered to enter rehab shortly after Wilson's death, and her two children, Zander, 6, and 9-month-old Zayne were taken from her. She was released after one day to undergo outpatient care.

McCready scored a number-one Billboard country hit in 1996 with "Guys Do It All the Time," but in recent years, the country crooner has received more media attention for her troubled personal life than her music.

She has been arrested multiple times on drug charges and probation violations and has been hospitalized for overdoses several times, including in 2010, when she was found unconscious at her mother's home after taking a painkiller and muscle relaxant.

Her mother, Gayle Inge, was appointed to be her son Zander's legal guardian in 2007 after McCready was arrested for violating probation on a drug-related charge. The boy's father is McCready's ex-boyfriend Billy McKnight.

Following a custody hearing in May 2011, McCready released a statement, saying, "We have progressed in a positive manner to reunite me and my son, Zander. I feel very optimistic this will happen in the near future."

But just six months later, in November 2011, was accused of violating a court order for failing to bring Zander back to her mother in Florida after a visit. The boy was placed in foster care while McCready and her mother worked out the custody dispute.

McCready's struggle with substance abuse was broadcast in 2010 on the third season of "Celebrity Rehab with Dr. Drew."

McCready also claimed to have carried on a decade-long affair with baseball star Roger Clemens that began was she was 15 years old and he was 28. Clemens denied that the relationship was sexual in nature.

"You know what, I don't think I'm ever going to be one of those people that has a normal, quiet existence," McCready told ABC Radio in 2010. "I've been chosen for some reason to be bigger and larger than life in every way. Negative and positive."

McCready, who was born and raised in southern Florida, moved to Nashville when she was 18 to start her music career.

Within a few months, she was starting to work with producer David Malloy, who got her tapes to RLG Records. The company signed her to a contract after seeing her in concert, giving her a record deal less than a year after her arrival in Nashville.

Her debut album, "Ten Thousand Angels," went gold within six months of its release in April 1996, and eventually went multi-platinum. Two more followed: "If I Don't Stay the Night," in 1997; and "I'm Not So Tough" in 1999.

Her most recent album, "I'm Still Here," featuring new versions of her early hits "Ten Thousand Angels" and "Guys Do It All the Time," was released in March 2010.
