New blood test finds elusive fetal gene problem



































A NEW non-invasive blood test for pregnant women could make it easier to catch abnormalities before their child is born.












Human cells should have two copies of each chromosome but sometimes the division is uneven. Existing tests count the fragments of placental DNA in the mother's blood. If the fragments from one chromosome are unusually abundant, it might be because the fetus has an extra copy of that chromosome. But triploidy, where there are three copies of every chromosome, is missed, since the proportion of fragments from each chromosome is the same.












California-based company Natera uses an algorithm to calculate the most likely genotype for the fetus. To do this it looks at single letter variations called SNPs in the parents and compares this to a database of the most common SNPs patterns in the population. This genotype is then compared with placental DNA.












This approach can catch triploidy since the whole fetal genotype is the reference rather than a single chromosome. The method was presented last week at the Society for Maternal-Fetal Medicine in San Francisco.

John Kerry embarks on sweeping tour of Europe, Mideast






WASHINGTON: America's top diplomat John Kerry began his first official trip as secretary of state on Sunday, a marathon get-acquainted tour of America's closest allies in Europe and the Middle East.

A plane carrying the news US secretary of state and his team took off from Joint Base Andrews outside Washington at around 7:15 am local time (1215 GMT).

Kerry will visit the United Kingdom, Germany, France, Italy, Turkey, Egypt, Saudi Arabia, the United Arab Emirates, and Qatar from February 24 to March 6.

The first stop will be London, where Kerry will meet with senior British officials, State Department Spokeswoman Victoria Nuland told reporters Friday.

Kerry travels on to Berlin where, in addition to meeting Germans, he will encounter his Russian counterpart, Sergei Lavrov, for a tricky exchange at a time when Moscow and Washington are at loggerheads on many issues.

"Obviously, they know each other well from when Secretary Kerry was Senator Kerry, but it will be their first opportunity to sit down bilaterally as foreign ministers," Nuland said.

Nuland added: "I would expect they'll talk about all of the issues -- bilateral, regional, global -- but with a particular emphasis, I would expect, on Syria, Iran, DPRK (North Korea) and the bilateral issues of the day."

The marathon trip underscores Washington's new foreign policy imperative, which is subtly pivoting away from Asia and increasingly towards Europe.

Tyson Barker of the Bertelsmann Foundation think tank said that, after a first term focused on relations with Pacific countries, President Barack Obama hopes "to consolidate and retro-fit some of our legacy relationships."

He added that Obama has in Kerry someone who is "comfortable engaging with Europe, and someone with whom Europe is comfortable engaging."

Kerry is a figure of standing in Washington.

He served for decades as a US senator, including a stint as the chairman of the chamber's Foreign Relations Committee. He was also the Democratic party's presidential nominee in 2004.

Among the issues high on his agenda during the marathon series of talks is a newly-announced effort to agree a mammoth free trade agreement between the United States and the European Union.

Obama announced the proposed Transatlantic Trade and Investment Partnership in his annual State of the Union address last month, and said the agreement would boost economic growth and jobs on both sides of the Atlantic.

Nuland added, on a personal note, that Kerry's visit to Berlin "will also be an opportunity to reconnect with the city in which he lived as a child."

The 69-year-old diplomat's father, Richard Kerry, was a Foreign Service officer who was posted in Berlin, where John Kerry lived before being sent to a Swiss boarding school at the age of 11.

Kerry travels from Germany to Paris, where Nuland said he would meet senior French officials to discuss American assistance for France's ongoing military operation against Islamist rebels in Mali.

On his next stop, in Rome, Kerry will concentrate on multilateral talks on the crisis in Syria.

However, Syria's main opposition umbrella group, the National Coalition, has canceled plans to attend international meetings on Syria in Italy, saying it wanted action not words from Arab and Western countries.

Instead, the coalition announced on Friday it would set up a government to run areas of the country "liberated" by rebels and would meet in Istanbul on March 2 to name a prime minister.

Kerry will travel to Ankara for meetings with Turkish officials on a range of strategic issues, including Syria.

His travels conclude in the Middle East.

In Egypt, Kerry will meet with political and business leaders and the secretary general of the Arab League, Nabil al-Arabi.

He will then go to Riyadh for meeting with Saudi leaders on "a broad range of shared concerns," said Nuland.

Kerry then visits Abu Dhabi, capital of the United Arab Emirates, and Doha, Qatar, key contacts for America as it confronts crises in Syria, Afghanistan, and the Middle East peace process.

Pistorius' brother faces homicide charge








By Holly Yan and Karen Smith, CNN


updated 8:38 AM EST, Sun February 24, 2013







Carl Pistorius, brother of Olympic and Paralympic athlete Oscar Pistorius, is shown Friday at a bail hearing for the runner.




STORY HIGHLIGHTS


  • A Pistorius family attorney confirms that Carl Pistorius is charged with culpable homicide

  • Prosecutors blame Carl Pistorius for the death of a motorcyclist in 2010

  • His attorney says the motorcyclist crashed into Carl Pistorius' vehicle

  • Carl Pistorius' trial was rescheduled so he could support his brother




(CNN) -- As Olympic icon Oscar Pistorius faces a murder trial for shooting his girlfriend, his older brother is also charged in the death of a woman.


Carl Pistorius is accused in the 2010 death of a female motorcyclist, Pistorius family attorney Kenny Oldwage said.


Culpable homicide refers to "unlawful negligent killing," South African police say.


Prosecutors say Carl Pistorius was driving recklessly in Vanderbijlpark, South Africa, when he crashed with the motorcyclist in the daytime.


Oldwage disputes allegations that his client was driving recklessly and said the motorcyclist rode into Carl Pistorius' vehicle.






"Carl deeply regrets the accident. Blood tests conducted by the police at the time proved that he had not been under the influence of alcohol, confirming that it was a tragic road accident after the deceased collided with Carl's car," a statement from the Pistorius family said.


The motorcyclist died in a hospital a couple of days after the accident, Oldwage said.


Carl Pistorius was initially scheduled to go on trial Thursday -- during the middle of his brother's four-day bail hearing.


But Carl Pistorius asked the court to postpone his trial so he could support his brother, and the court agreed.


The trial has been rescheduled for the end of March. His case could be over before his brother's murder trial is scheduled to start in June.


Carl Pistorius was a fixture at his younger brother's bail hearing last week, handing Oscar tissues as the 26-year-old sobbed uncontrollably in court.


Oscar Pistorius, the double-amputee sprinter known as the "Blade Runner," is charged with premeditated murder in the death of his girlfriend, model Reeva Steenkamp. Prosecutors say the Olympian killed her after a heated argument in the early morning hours of Valentine's Day.


Pistorius says he thought Steenkamp, 29, was an intruder.


After a four-day, emotionally wrenching bail hearing, the track star was granted bail Friday.


As part of his conditions for release, Oscar Pistorius cannot return to his home, where the shooting happened; must surrender his passport; and can't go near an airport.


It's unknown whether Oscar Pistorius will be in court to support his brother during his trial.


CNN's Nkepile Mabuse and Josh Levs contributed to this report.

NASCAR has some cleaning and explaining to do

DAYTONA BEACH, Fla .With the start of the Daytona 500 just hours away, NASCAR officials still have some cleaning up to do amid growing questions about fan safety.

The season opener will go off as planned Sunday less than 24 hours after at least 33 people were injured when a car flew into the fence during a NASCAR race at Daytona International Speedway, sending a tire and large pieces of debris sailing into the stands.

"Just seeing the carnage on the racetrack, it was truly unbelievable," driver Justin Allgaier said.

Fans injured in crash at Daytona



The final-lap accident Saturday marred the second-tier Nationwide Series race on the eve of a spectacle often called the Super Bowl of motorsports. Late into the night, track workers were scrambling to repair a huge section of fence that separates fans from the high-speed track.

Nathan Kimpel, 24, who works at a concession stand near where the crash happened, told CBS News correspondent Adriana Diaz that he saw 10 to 15 fans being carried out on stretchers.

"As soon as I saw the accident I just turned my head because I didn't want to get injured or anything," Kimpel told Diaz. "I saw the fence separate and more pieces of car parts flying up."

Meghan Willams, 20, who also works at a concession stand, told Diaz the crash sounded like an "earthquake." She saw people running and crying and a girl completely covered in engine oil.

Byron Cogdell, a spokesman for Halifax Health Medical Center, told CBS News that one of the 11 patents taken to the hospital was in critical condition and five more were listed as "trauma" patients.

Speedway President Joie Chitwood III has a news conference scheduled for Sunday morning to give the latest update on repairs and any safety changes that could be made before the "Great American Race."

The 12-car crash began about 200 feet from the start-finish line as the front-runners approached the checkered flag. Leader Regan Smith attempted to block Brad Keselowski for the win, triggering a horrific pileup that could have been much worse.

The front end of Larson's No. 32 car was sheared off, and his burning engine wedged through a gaping hole in the fence. Parts and pieces of his car sprayed into the stands, including a tire that cleared the top of the fence and landed midway up the spectator section closest to the track.

The 20-year-old Larson stood in shock a few feet from his car as fans in the stands waved frantically for help. Smoke from the burning engine briefly clouded the area, and emergency vehicles descended on the scene.

Ambulance sirens could be heard wailing behind the grandstands at a time the race winner would typically be doing celebratory burnouts.

"It was freaky. When I looked to my right, the accident happened," Rick Harpster of Orange Park said. "I looked over and I saw a tire fly straight over the fence into the stands, but after that I didn't see anything else. That was the worst thing I have seen, seeing that tire fly into the stands. I knew it was going to be severe."

Shannan Devine of Egg Harbor Township, N.J., was sitting about 250 feet from where the car smashed into the fence and could see plumes of smoke directly in front of her.

"I didn't know if there was a car on top of people. I didn't know what to think," she said. "I'm an emotional person and I immediately started to cry. It was very scary. Absolutely scary. I love the speed of the sport. But it's so dangerous."

Chitwood said 14 fans were treated on site and 14 others were taken to hospitals. Local officials said 19 people were taken to neighboring hospitals, including two who were in critical but stable condition.

Because of potential injuries, race winner Tony Stewart skipped the traditional victory celebration.

Stewart, who won for the 19th time at Daytona and seventh time in the last nine season-opening Nationwide races, was in no mood to celebrate.

"The important thing is what is going on on the frontstretch right now," said Stewart, a three-time NASCAR champion. "We've always known, and since racing started, this is a dangerous sport. But it's hard. We assume that risk, but it's hard when the fans get caught up in it.

"So as much as we want to celebrate right now and as much as this is a big deal to us, I'm more worried about the drivers and the fans that are in the stands right now because that was ... I could see it all in my mirror, and it didn't look good from where I was at."

Crash at Daytona Exposes Risks to Fans












The risks of racing extend beyond the drivers.



Fans can wind up in the danger zone, too.



A horrifying crash on the last lap of a race at Daytona International Speedway injured at least 30 fans Saturday and provided another stark reminder of what can happen when a car going nearly 200 mph is suddenly launched toward the spectator areas.



The victims were sprayed with large chunks of debris — including a tire — after rookie Kyle Larson's machine careened into the fencing that is designed to protect the massive grandstands lining NASCAR's most famous track.



"I love the sport," said Shannan Devine, who witnessed the carnage from her 19th-row seat, about 250 feet away. "But no one wants to get hurt over it."



The fencing served its primary purpose, catapulting what was left of Larson's car back onto the track. But it didn't keep potentially lethal shards from flying into the stands.



"There was absolute shock," Devine said. "People were saying, 'I can't believe it, I can't believe it. I've never seen this happen, I've never seen this happen. Did the car through the fence?' It was just shock and awe. Grown men were reaching out and grabbing someone, saying, 'Oh my gosh! Oh my gosh!' It was just disbelief, absolute disbelief."



From Daytona to Le Mans to a rural road in Ireland, auto racing spectators have long been too close to the action when parts start flying. The crash in the second-tier Nationwide race follows a long list of accidents that have left fans dead or injured.





The most tragic incident occurred during the 1955 24 Hours of Le Mans, when two cars collided near the main stands. The wreck sent debris hurtling into the crowd, while one of the cars flipped upside down and exploded in a giant fireball.



Eighty-three spectators and driver Pierre Levegh were killed, and 120 fans were injured.



The Daytona crash began as the field approached the checkered flag and leader Regan Smith attempted to block Brad Keselowski. That triggered a chain reaction, and rookie Kyle Larson hit the cars in front of him and went airborne into the fence.



The entire front end was sheared off Larson's car, and his burning engine wedged through a gaping hole in the fence. Chunks of debris from the car were thrown into the stands, including a tire that cleared the top of the fence and landed midway up the spectator section closest to the track.



"I thought the car went through the fence," Devine said. "I didn't know if there was a car on top of people. I didn't know what to think. I'm an emotional person. I immediately started to cry. It was very scary, absolutely scary. I love the speed of the sport. But it's so dangerous."



The fencing used to protect seating areas and prevent cars from hurtling out of tracks has long been part of the debate over how to improve safety.



Three-time Indianapolis 500 winner Dario Franchitti lost close friend Dan Wheldon at Las Vegas in the 2011 IndyCar season finale, when Wheldon's car catapulted into the fencing and his head struck a support post. Since his death, IndyCar drivers have called for studies on how to improve the safety barriers.



Franchitti renewed the pleas on Twitter after the Daytona crash, writing "it's time (at)Indycar (at)nascar other sanctioning bodies & promoters work on an alternative to catch fencing. There has to be a better solution."



Another fan who witnessed the crash said he's long worried that sizable gaps in the fencing increase the chances of debris getting through to the stands.

Amazon to open market in second-hand MP3s and e-books






















A new market for second-hand digital downloads could let us hold virtual yard sales of our ever-growing piles of intangible possessions






















WHY buy second-hand? For physical goods, the appeal is in the price – you don't mind the creases in a book or rust spots on a car if it's a bargain. Although digital objects never lose their good-as-new lustre, their very nature means there is still uncertainty about whether we actually own them in the first place, making it tricky to set up a second-hand market. Now an Amazon patent for a system to support reselling digital purchases could change that.












Amazon's move comes after last year's European Union ruling that software vendors cannot stop customers from reselling their products. But without technical support, the ruling has had no impact. In Amazon's system, customers will keep their digital purchases – such as e-books or music – in a personal data store in the cloud that only they can access, allowing them to stream or download the content.












This part is like any cloud-based digital locker except that the customer can resell previous purchases by passing the access rights to another person. Once the transaction is complete, the seller will lose access to the content. Any system for reselling an e-book, for example, would have to ensure that it is not duplicated in the transaction. That means deleting any copies the seller may have lying around on hard drives, e-book readers, and other cloud services, since that would violate copyright.












Amazon may be the biggest company to consider a second-hand market, but it is not the first. ReDigi, based in Boston, has been running a resale market for digital goods since 2011. After downloading an app, users can buy a song on ReDigi for as little as 49 cents that would costs 99 cents new on iTunes.












When users want to sell an item, they upload it to ReDigi's servers via a mechanism that ensures no copy is made during the transfer. Software checks that the seller does not retain a copy. Once transferred, the item can be bought and downloaded by another customer. ReDigi is set to launch in Europe in a few months.












Digital items on ReDigi are cheaper because they are one-offs. If your hard drive crashes and you lose your iTunes collection you can download it again. But you can only download an item from ReDigi once – there is no other copy. That is the trade-off that makes a second-hand digital market work: the risk justifies the price. The idea has ruffled a few feathers – last year EMI sued ReDigi for infringement of copyright. A judge denied the claim, but the case continues.


















Used digital goods can also come with added charm. ReDigi tracks the history of the items traded so when you buy something, you can see who has owned it and when. ReDigi's second-hand marketplace has grown into a social network. According to ReDigi founder John Ossenmacher, customers like seeing who has previously listened to a song. "It's got soul like an old guitar," he says. "We've introduced this whole feeling of connectedness."












It could be good for business too if the original vendors, such as iTunes, were to support resale and take a cut of the resell price. Nevertheless, Amazon's move bucks the industry trend. Microsoft's new Xbox, for example, is expected not to work with second-hand games.












But the market could change rapidly now that Amazon's weight is behind this, says Ossenmacher. "The industry is waking up."

STORY HIGHLIGHTS


  • The massive system sweeping the U.S. wraps up with a wet finale

  • The far Northeast should see snow

  • Slushy snow or rain should fall from Boston on down




(CNN) -- It will be a messy weekend in the Northeast and the Deep South as the massive weather system that walloped 20 states with a snowstorm rolls off toward the Atlantic Ocean.


A winter storm is expected to deposit up to 10 inches of snow in isolated pockets of western Massachusetts, and 6 inches to a foot in parts of southern Vermont and New Hampshire, and central Maine.


This is not the same storm that blanketed the Great Plains, said CNN Meteorologist Pedram Javaheri, although it is part of the same overall system that spans the country from north to south.


It will be much less intense, he said, and it should not affect the places hardest hit by the blizzard that plastered the Northeast two weeks ago, knocking out power to hundreds of thousands of customers.








Boston will likely see a slushy mix of rain and snow that could lead to downed branches and power lines, Javaheri said.


Track severe weather


Rain will continue to soak the eastern United States from Washington, D.C., on down, especially Sunday, according to the National Weather Service.


"Across the Southeast, some of the rainfall totals are going to be staggering," said CNN Meteorologist Karen McGinnis. Parts of the central Southeast should get 4 -- 6 inches of rainfall.


Some snow records


The outgoing system will have made its mark on virtually the entire country from the southwest corner of California to central Maine, leaving its deepest imprint on Kansas.


Wichita saw its second-highest storm snowfall total on record with 14.2 inches over two days, the National Weather Service said.


The town of Russell in the state's middle lay under a 22 inch layer of white by the time the storm roared by.


Missouri was not far behind, with accumulations of around a foot in some places.


The snow set a record at Kansas City International Airport, with 9 inches falling in a single day. The old record was 5.1 inches set in 2010.


Some businesses and universities shut down Thursday as state officials urged residents to stay off the roads.


The white blanket emptied the streets of Kansas City.


Silver lining


The snowstorm turned out to be a welcome one to many Kansans and many others throughout the Great Plains, who have been suffering a drought for a third straight year.


Kansas, Nebraska, Iowa, Missouri and a host of other farm-heavy states have seen crop losses as a result.


The Kansas Department of Agriculture expects those conditions to continue into April, but near-record levels of snowfall will ease the problem and could accelerate the drought's end.


"It snows so infrequently here. Now we've been in a really bad drought for several years; really, really hot summer and just no moisture. So we're thrilled to see snow or ice -- whatever moisture we can get," Wichita resident Kristen Woodburn said.


Ranchers embraced the storm, even though bitter cold snow can be deadly during calving season.


Frank Harper, a Kansas rancher from Sedgwick and the immediate past president of the Kansas Livestock Association, said the storm caused more work for him because he had to bring his calves inside to warm them up.


But he called the snowstorm a blessing for bringing good moisture to the winter wheat.

Pentagon grounds F-35 fleet after engine crack found

Updated 9:03 PM ET

WASHINGTON The Pentagon on Friday grounded its fleet of F-35 fighter jets after discovering a cracked engine blade in one plane.

The problem was discovered during what the Pentagon called a routine inspection at Edwards Air Force Base, Calif., of an F-35A, the Air Force version of the sleek new plane. The Navy and the Marine Corps are buying other versions of the F-35, which is intended to replace older fighters like the Air Force F-16 and the Navy F/A-18.

All versions -- a total of 51 planes -- were grounded Friday pending a more in-depth evaluation of the problem discovered at Edwards. None of the planes have been fielded for combat operations; all are undergoing testing.

In a brief written statement, the Pentagon said it is too early to know the full impact of the newly discovered problem.

A watchdog group, the Project on Government Oversight, said the grounding is not likely to mean a significant delay in the effort to field the stealthy aircraft.

"The F-35 is a huge problem because of its growing, already unaffordable, cost and its gigantically disappointing performance," the group's Winslow Wheeler said. "That performance would be unacceptable even if the aircraft met its far-too-modest requirements, but it is not."

The F-35 is the Pentagon's most expensive weapons program at a total estimated cost of nearly $400 billion. The Pentagon envisions buying more than 2,400 F-35s, but some members of Congress are balking at the price tag.

Friday's suspension of flight operations will remain in effect until an investigation of the problem's root cause is determined.

The Pentagon said the engine in which the problem was discovered is being shipped to a Pratt & Whitney facility in Connecticut for more thorough evaluation.

6 Leaking Tanks Are Wash. Nuke Site's Latest Woe











Federal and state officials say six underground tanks holding a brew of radioactive and toxic waste are leaking at the country's most contaminated nuclear site in south-central Washington, raising concerns about delays for emptying the aging tanks.



The leaking materials at Hanford Nuclear Reservation pose no immediate risk to public safety or the environment because it would take perhaps years for the chemicals to reach groundwater, Washington Gov. Jay Inslee said Friday.



But the news has renewed discussion over delays for emptying the tanks, which were installed decades ago and are long past their intended 20-year life span.



"None of these tanks would be acceptable for use today. They are all beyond their design life. None of them should be in service," said Tom Carpenter of Hanford Challenge, a Hanford watchdog group. "And yet, they're holding two-thirds of the nation's high-level nuclear waste."



Just last week, state officials announced that one of Hanford's 177 tanks was leaking 150 to 300 gallons a year, posing a risk to groundwater and rivers. So far, nearby monitoring wells haven't detected higher radioactivity levels.



Inslee then traveled to Washington, D.C., to discuss the problem with federal officials, learning in meetings Friday that six tanks are leaking.






AP Photo/Shannon Dininny, File








The declining waste levels in the six tanks were missed because only a narrow band of measurements was evaluated, rather than a wider band that would have shown the levels changing over time, Inslee said.



"It's like if you're trying to determine if climate change is happening, only looking at the data for today," he said. "Perhaps human error, the protocol did not call for it. But that's not the most important thing at the moment. The important thing now is to find and address the leakers."



Department of Energy spokeswoman Lindsey Geisler said there was no immediate health risk and that federal officials would work with Washington state to address the matter.



Regardless, Sen. Ron Wyden, the new chairman of the Senate Energy and Natural Resources Committee, will ask the Government Accountability Office to investigate Hanford's tank monitoring and maintenance program, said his spokesman, Tom Towslee.



The federal government built the Hanford facility at the height of World War II as part of the Manhattan Project to build the atomic bomb. The remote site produced plutonium for the bomb dropped on Nagasaki, Japan, and continued supporting the nation's nuclear weapons arsenal for years.



Today, it is the most contaminated nuclear site in the country, still surrounded by sagebrush but with Washington's Tri-Cities of Richland, Kennewick and Pasco several miles downriver.



Several years ago, workers at Hanford completed two of three projects deemed urgent risks to the public and the environment, removing all weapons-grade plutonium from the site and emptying leaky pools that held spent nuclear fuel just 400 yards from the river.



But successes at the site often are overshadowed by delays, budget overruns and technological challenges. Nowhere have those challenges been more apparent than in Hanford's central plateau, home to the site's third most urgent project: emptying the tanks.



Hanford's tanks hold some 53 million gallons of highly radioactive waste — enough to fill dozens of Olympic-size swimming pools — and many of those tanks are known to have leaked in the past. An estimated 1 million gallons of radioactive liquid has already leaked there.
