Serial Killer 'Broke Own Rule,' Lost Control

Serial killer Israel Keyes' capture was his own undoing. It was the meticulous murderer's loss of control and violation of his own careful rules of murder that ended years of traveling to kill for fun.

When Keyes, 34, approached an Anchorage coffee stand Feb. 1, he told himself that if the person working inside did not have her own car, he would only rob the place and leave.

But when he approached and found teenage barista Samantha Koenig by herself, he couldn't help himself, Keyes told police. He dragged her out, into his own car, raped her, strangled her and was eventually arrested for her murder.

"In prior cases, he had enough self-control to walk away from it, to not commit the kidnapping, to not commit the abduction and with Samantha he didn't," Anchorage homicide Det. Monique Doll said Monday. "He broke his own rule. He had drawn his line in the sand and he couldn't help himself, he said. He took her anyway."

The arrest of Keyes on March 12 ended more than a decade of traveling around the country to find victims to kill or to prepare for future crimes by burying murder kits of weapons, cash and tools to dispose of bodies. Since March he had been slowly telling police about his hidden life and how he operated. But the tale abruptly ended when Keyes committed suicide in his jail cell on Dec. 1.

Police are now left trying to fill in the details of his vicious life. Police believe he killed between 8 and 12 people, including Koenig, but only three victims have been definitively tied to Keyes so far.

Before his jail cell suicide, Keyes gave authorities some clues on how he managed to remain undetected for so long.

"He basically had this rule, this unwritten rule, that he would travel outside and go to great lengths to distance himself from any of his victims," Doll said. "He told us he was losing control. He was losing the massive amount of self-control that he had."

Koenig's abduction broke Keyes' rules on two levels. First, she was in Anchorage, which was also Keyes' home. Second, she did not have her own vehicle.

"Mr. Keyes told us that he was deciding as he walked up the coffee kiosk that if the person working inside did not have a vehicle he was only going to rob the [place] and walk away because he did not want to transport his victim in his vehicle," Doll said.

Keyes quickly discovered that Koenig did not have a car, but when he saw her, his desire to kill overpowered his discipline.

This admission was among many startling revelations Keyes made over about 40 hours of interviews with police in which he discussed topics ranging from torturing animals as a child to the way he fantasized his own death.

"He didn't plan on being taken alive," Anchorage Police Officer Jeff Bell said at the news conference.

Keyes envisioned himself being caught robbing a bank and dying in a police shootout, Bell said. For this reason, he would bring two guns with him to bank robberies--the gun used to rob the bank and a second gun hidden in his coat with 100 rounds for a shootout.

Keyes also talked about his interest in serial killers, though he was adamant about not being called a serial killer.

"He had researched and read other serial killers. He knew a lot about Ted Bundy," Doll said. "He was very careful to say that he had not patterned himself after any other serial killers, that his ideas were his own. He was very clear about that distinction. That mattered a lot to him."

"He never identified himself as a serial killer," she said. "That was one of the things that he wanted very much, as this investigation progressed, to keep from being identified as."

Doll said Keyes was interested in suspense and crime movies and books, which he said he enjoyed because he recognized himself in the characters in a way that he could never talk about.

US stocks edge up amid hopes for 'cliff' deal

NEW YORK: US stocks ended slightly higher Monday amid hopes that a political deal over the looming fiscal cliff was in the works.

Markets showed little effect from the fresh turmoil in the eurozone, after Italian Prime Minister Mario Monti said he would resign in the coming days and Silvio Berlusconi threatened a comeback on an anti-austerity platform.

The Dow Jones Industrial Average rose 14.75 points (0.11 percent) to 13,169.88.

The broad-market S&P 500 added 0.48 (0.03 percent) to 1,418.55, while the tech-rich Nasdaq Composite rose 8.92 points (0.30 percent) to 2,986.96.

Trade was light and in a narrow range, with transportation, technology and basic materials shares strongest, while consumer goods slipped.

Troubled Hewlett-Packard surged 2.6 percent on rumors that raider Carl Icahn was moving on the company.

Canadian energy firm Nexen added 13.8 percent after Canadian regulators approved its takeover by Chinese state oil giant CNOOC late Friday.

Excepting Apple (-0.6 percent), big tech stocks were higher: Facebook 1.3 percent, Google 0.2 percent, Cisco 2.4 percent and STMicroelectronics, which said it was leaving a joint venture with Ericsson, added 3.4 percent.

Bond prices edged higher. The 10-year US Treasury yield slipped to 1.62 percent from 1.63 percent late Friday, while the 30-year fell to 2.80 percent from 2.81 percent.

Bond prices and yields move inversely.

FTC re-slams apps for kids over privacy concerns

FTC follow up report on app privacy for kids shows little progress being made

(Credit:
FTC.gov)

In February, 2012 the Federal Trade Commission (FTC) issued a report titled Mobile Apps for Kids: Current Privacy Disclosures are Disappointing (PDF) that pointed out that there was "little or no" privacy information available to parents in the
Android Google Play and Apple iOS app stores prior to download and scarce data in the apps themselves or on the app vendors websites.

And on Monday, the FTC issued a follow up report, Mobile Apps for Kids Disclosures Still Not Making the Grade that complains that "despite many high-visibility efforts to increase transparency in the mobile marketplace, little or no progress has been made."

Findings
The new report noted that since the first report, "the market for mobile apps has continued to grow at an explosive rate." There are now over 700,000 apps in the Apple app store (up 40% since December 2011) and an equal number in the Google Play store, "an 80% increase since the beginning of 2012," according to the FTC.

FTC staff downloaded nearly 1,000 apps that had the keyword "kids" and then randomly selected 200 each from the Apple App store and Google Play. The report found that "Only 20 percent of the apps staff reviewed disclosed any information about the app's privacy practices," and that nearly 60 percent of the apps surveyed are transmitting user information back to the developer or (more commonly) to an advertising network analytics company or other third party.

The report also stated that 58% of the apps (230) contained advertising within the app, "while only 15% (59) indicated the presence of advertising prior to download."

The report also found that 22% percent of the apps "contained links to social networking services, while only nine percent disclosed that fact." Budget minded parents might note that 17 percent of the apps allowed kids to make purchases for virtual goods within the app and that "although both stores provided certain indicators when an app contained in-app purchasing capabilities, these indicators were not always prominent and, even if noticed, could be difficult for many parents to understand."

Regulations coming?
In what could be a prelude to proposed regulation, the FTC is urging the mobile app industry to develop "best practices" that:

1. Incorporate privacy protections into the design of mobile products and services ("privacy by design")
2. Offer parents easy-to-understand choices about the data collection and sharing through kids' apps
3. Provide greater transparency about how data is collected, used, and shared through kids' apps.

Recommendations for the industry and parents
These findings should be a wake-up call to what FTC calls the "app industry." If app developers, many of which are very small businesses, don't get their own act together on privacy, it's a pretty safe bet that the FTC and Congress will impose some pretty strict rules. Unfortunately, Congress sometimes legislates with an ax rather than a scalpel, so it would be in the app developers' interest to try to preempt such legislation or -- at the very least -- to make sure it deals with abuses and doesn't punish companies that are trying to do the right thing.

Regardless of what the government might do, parents still need to be aware of the apps their kids are using and how they affect their kids' privacy. In the absence of good information from app developers, at least read user reviews and try out the apps yourself (or with your kids) to see what information they are collecting and passing on. Pay special attention to location, access to contact information, in-app purchases, and information that children are encouraged to disclose within the app.

U.K. Dash for Shale Gas a Test for Global Fracking

Thomas K. Grose in London

The starting gun has sounded for the United Kingdom's "dash for gas," as the media here have dubbed it.

As early as this week, a moratorium on shale gas production is expected to be lifted. And plans to streamline and speed the regulatory process through a new Office for Unconventional Gas and Oil were unveiled last week in the annual autumn budget statement by the chancellor of the exchequer, George Osborne.

In the U.K., where all underground mineral rights concerning fossil fuels belong to the crown, hydraulic fracturing, or fracking, could unlock a new stream of government revenue as well as fuel. But it also means that there is no natural constituency of fracking supporters as there is in the United States, birthplace of the technology. In the U.S., concerns over land and water impact have held back fracking in some places, like New York, but production has advanced rapidly in shale basins from Texas to Pennsylvania, with support of private landowners who earn royalties from leasing to gas companies. (Related: "Natural Gas Stirs Hope and Fear in Pennsylvania")

A taste of the fight ahead in the U.K. came ahead of Osborne's speech last weekend, when several hundred protesters gathered outside of Parliament with a mock 23-foot (7-meter) drilling rig. In a letter they delivered to Prime Minister David Cameron, they called fracking "an unpredictable, unregulatable process" that was potentially toxic to the environment.

Giving shale gas a green light "would be a costly mistake," said Andy Atkins, executive director of the U.K.'s Friends of the Earth, in a statement. "People up and down the U.K. will be rightly alarmed about being guinea pigs in Osborne's fracking experiment. It's unnecessary, unwanted and unsafe."

The government has countered that natural gas-fired power plants would produce half the carbon dioxide emissions of the coal plants that still provide about 30 percent of the U.K.'s electricity. London Mayor Boris Johnson, viewed as a potential future prime minister, weighed in Monday with a blistering cry for Britain to "get fracking" to boost cleaner, cheaper energy and jobs. "In their mad denunciations of fracking, the Greens and the eco-warriors betray the mindset of people who cannot bear a piece of unadulterated good news," he wrote in the Daily Telegraph. (Related Quiz: "What You Don't Know About Natural Gas")

Energy Secretary Edward Davey, who is expected this week to lift the U.K.'s year-and-a-half-old moratorium on shale gas exploration, said gas "will ensure we can keep the lights on as increasing amounts of wind and nuclear come online through the 2020s."

A Big Role for Gas

If the fracking plan advances, it will not be the first "dash for gas" in the U.K. In the 1980s, while Prime Minister Margaret Thatcher battled with mining unions, she undercut their clout by moving the nation toward generating a greater share of its electricity from natural gas and less from coal. So natural gas already is the largest electricity fuel in Britain, providing 40 percent of electricity. (Related Interactive: "World Electricity Mix")

The United Kingdom gets about 10 percent of its electricity from renewable energy, and has plans to expand its role. But Davey has stressed the usefulness of gas-fired plants long-term as a flexible backup source to the intermittent electricity generated from wind and solar power. Johnson, on the other hand, offered an acerbic critique of renewables, including the "satanic white mills" he said were popping up on Britain's landscape. "Wave power, solar power, biomass—their collective oomph wouldn't pull the skin off a rice pudding," he wrote.

As recently as 2000, Great Britain was self-sufficient in natural gas because of conventional gas production in the North Sea. But that source is quickly drying up. North Sea production peaked in 2000 at 1,260 terawatt-hours (TWH); last year it totaled just 526 TWh.

Because of the North Sea, the U.K. is still one of the world's top 20 producers of gas, accounting for 1.5 percent of total global production. But Britain has been a net importer of gas since 2004. Last year, gas imports—mainly from Norway, Belgium, and the Netherlands—accounted for more than 40 percent of domestic demand.

The government hopes to revive domestic natural gas production with the technology that has transformed the energy picture in the United States—horizontal drilling into deep underground shale, and high-pressure injection of water, sand, and chemicals to create fissures in the rock to release the gas. (Related Interactive: "Breaking Fuel From the Rock")

A Tougher Road

But for a number of reasons, the political landscape is far different in the United Kingdom. Britain made a foray into shale gas early last year, with a will drilled near Blackpool in northwest England. The operator, Cuadrilla, said that that area alone could contain 200 trillion cubic feet of gas, which is more than the known reserves of Iraq. But the project was halted after drilling, by the company's own admission, caused two small earthquakes. (Related: "Tracing Links Between Fracking and Earthquakes" and "Report Links Energy Activities To Higher Quake Risk") The April 2011 incident triggered the moratorium that government now appears to be ready to lift. Cuadrilla has argued that modifications to its procedures would mitigate the seismic risk, including lower injection rates and lesser fluid and sand volumes. The company said it will abandon the U.K. unless the moratorium is soon lifted.

A few days ahead of Osborne's speech, the Independent newspaper reported that maps created for Britain's Department of Energy and Climate Change (DECC) showed that 32,000 square miles, or 64 percent of the U.K. countryside, could hold shale gas reserves and thus be open for exploration. But a DECC spokeswoman said "things are not quite what it [the Independent story] suggests." Theoretically, she said, those gas deposits do exist, but "it is too soon to predict the scale of exploration here." She said many other issues, ranging from local planning permission to environmental impact, would mean that some tracts would be off limits, no matter how much reserve they held. DECC has commissioned the British Geological Survey to map the extent of Britain's reserves.

Professor Paul Stevens, a fellow of the Royal Institute of International Affairs, said the U.K. is clearly interested in trying to replicate America's shale gas revolution. "That's an important part of the story," he said, but trying to use the American playbook won't be easy. "It's a totally different ballgame." In addition to the fact that mineral rights belong to the crown, large expanses of private land that are commonplace in America don't exist in England. Just as important, there is no oil- and gas-service industry in place in Britain to quickly begin shale gas operations here. "We don't have the infrastructure set up," said Richard Davies, director of the Durham Energy Institute at Durham University, adding that it would take years to build it.

Shale gas production would also likely ignite bigger and louder protests in the U.K. and Europe. "It's much more of a big deal in Europe," Stevens said. "There are more green [nongovernmental organizations] opposed to it, and a lot more local opposition."

In any case, the U.K. government plans to move ahead. Osborne said he'll soon begin consultations on possible tax breaks for the shale gas industry. He also announced that Britain would build up to 30 new natural gas-fired power plants with 26 gigawatts (GW) of capacity. The new gas plants would largely replace decommissioned coal and nuclear power plants, though they would ultimately add 5GW of additional power to the U.K. grid. The coalition government's plan, however, leaves open the possibility of increasing the amount of gas-generated electricity to 37GW, or around half of total U.K. demand.

The U.S. Energy Information Administration (EIA) estimates that Europe may have as much as 600 trillion cubic feet of shale gas that could be recovered. But Stevens said no European country is ready to emulate the United States in producing massive amounts of unconventional gas. They all lack the necessary service industry, he said, and geological differences will require different technologies. And governments aren't funding the research and development needed to develop them.

Globally, the track record for efforts to produce shale gas is mixed:

• In France, the EIA's estimate is that shale gas reserves total 5 trillion cubic meters, or enough to fuel the country for 90 years. But in September, President Francois Hollande pledged to continue a ban on fracking imposed last year by his predecessor, Nicolas Sarkozy.
• Poland was also thought to have rich shale gas resources, but initial explorations have determined that original estimates of the country's reserves were overstated by 80 percent to 90 percent. After drilling two exploratory wells there, Exxon Mobil stopped operations. But because of its dependence on Russian gas, Poland is still keen to begin shale gas production.
• South Africa removed a ban on fracking earlier this year. Developers are eyeing large shale gas reserves believed to underlie the semidesert Karoo between Johannesburg and Cape Town.
• Canada's Quebec Province has had a moratorium on shale gas exploration and production, but a U.S. drilling company last month filed a notice of intent to sue to overturn the ban as a violation of the North American Free Trade Agreement.
• Germany's Environment Ministry has backed a call to ban fracking near drinking water reservoirs.
• China drilled its initial shale gas wells this year; by 2020, the nation's goal is for shale gas to provide 6 percent of its massive energy needs. The U.S. government's preliminary assessment is that China has the world's largest "technically recoverable" shale resources, about 50 percent larger than stores in the United States.

New Evidence Suggests Biblical Flood Happened

The story of Noah's Ark and the Great Flood is one of the most famous from the Bible, and now an acclaimed underwater archaeologist thinks he has found proof that the biblical flood was actually based on real events.

In an interview with Christiane Amanpour for ABC News, Robert Ballard, one of the world's best-known underwater archaeologists, talked about his findings. His team is probing the depths of the Black Sea off the coast of Turkey in search of traces of an ancient civilization hidden underwater since the time of Noah.

Tune in to Christiane Amanpour's two-part ABC News special, "Back to the Beginning," which explores the history of the Bible from Genesis to Jesus. Part one airs on Friday, Dec. 21 and part two on Friday, Dec. 28, both starting at 9 p.m. ET on ABC. See photos from her journey HERE

Ballard's track record for finding the impossible is well known. In 1985, using a robotic submersible equipped with remote-controlled cameras, Ballard and his crew hunted down the world's most famous shipwreck, the Titanic.

Now Ballard is using even more advanced robotic technology to travel farther back in time. He is on a marine archeological mission that might support the story of Noah. He said some 12,000 years ago, much of the world was covered in ice.

"Where I live in Connecticut was ice a mile above my house, all the way back to the North Pole, about 15 million kilometers, that's a big ice cube," he said. "But then it started to melt. We're talking about the floods of our living history."

The water from the melting glaciers began to rush toward the world's oceans, Ballard said, causing floods all around the world.

"The questions is, was there a mother of all floods," Ballard said.

According to a controversial theory proposed by two Columbia University scientists, there really was one in the Black Sea region. They believe that the now-salty Black Sea was once an isolated freshwater lake surrounded by farmland, until it was flooded by an enormous wall of water from the rising Mediterranean Sea. The force of the water was two hundred times that of Niagara Falls, sweeping away everything in its path.

Fascinated by the idea, Ballard and his team decided to investigate.

"We went in there to look for the flood," he said. "Not just a slow moving, advancing rise of sea level, but a really big flood that then stayed... The land that went under stayed under."

Four hundred feet below the surface, they unearthed an ancient shoreline, proof to Ballard that a catastrophic event did happen in the Black Sea. By carbon dating shells found along the shoreline, Ballard said he believes they have established a timeline for that catastrophic event, which he estimates happened around 5,000 BC. Some experts believe this was around the time when Noah's flood could have occurred.

"It probably was a bad day," Ballard said. "At some magic moment, it broke through and flooded this place violently, and a lot of real estate, 150,000 square kilometers of land, went under."

The theory goes on to suggest that the story of this traumatic event, seared into the collective memory of the survivors, was passed down from generation to generation and eventually inspired the biblical account of Noah.

Noah is described in the Bible as a family man, a father of three, who is about to celebrate his 600th birthday.

Female lemurs avoid the wrong love in the dark

IT IS the ultimate voice-recognition system. Without ever meeting him, a female lemur still knows the call of her father.

The ability to identify family members is important to avoid inbreeding. For large-brained mammals like apes that engage in complex social interactions this is relatively straightforward. Now, a team has shown that nocturnal grey mouse lemurs appear to do the same, even though lemurs are reared exclusively by their mothers (BMC Ecology, doi.org/jvx).

Study leader Sharon Kessler of Arizona State University in Tempe, believes that the young lemurs may associate calls similar to their own, or to those of male siblings, with their fathers.

Football: Barca legend Messi beats Mueller record

MADRID: Lionel Messi surpassed Gerd Mueller's record of 85 goals in a calendar year with a first-half double that helped his side to an important 2-1 win at Real Betis on Sunday.

The Argentinian moved up to 86 goals in 2012 but was only given the go-ahead to play against Betis before the game after injuring his knee in the midweek Champions League game against Benfica.

He beats the German legend's record set in 1972, and now has 23 in the league this season, six more than Radamel Falcao who hit five goals for Atletico in their win.

It did not take long for Messi to equal Mueller's record with his side's first real attack on 16 minutes, making a diagonal run across the Betis defence before hitting a left footed shot into the right hand corner.

His history-making moment came nine minutes later when he struck from almost an identical position after good play from Adriano and Andres Iniesta.

Betis had started and finished the better side in Seville, Salva Sevilla had a header well saved by Victor Valdes on three minutes and they hit the woodwork on three occasions in the second-half.

Adrian in the Betis goal then made an acrobatic save to deny Xavi Hernandez, and the home side appeared out of the game until substitute Alvaro Vadillo played a clever pass to Ruben Castro who finished coolly to reduce Barca's lead before the interval.

Valdes saved Barca six minutes into the second period, plucking a left-wing volley from Sevilla from under the crossbar.

The game continued from end-to-end at a frantic pace without many clear-cut chances until Barca's Javier Mascherano struck his own post whilst trying to clear a corner with twenty minutes remaining.

Jorge Molina then hit a post with a fierce shot while at the other end Adrian blocked well from Pedro Rodriguez before Jordi Alba hit the bar when he should have scored.

Barca were in danger of conceding until the end but held on for a vital three points where rivals Real Madrid lost 1-0 only two weeks ago.

The win keeps Barca six points ahead of Atletico Madrid at the top of La Liga who had earlier thrashed Deportivo La Coruna 6-0.

Falcao became the first La Liga player in a decade to score five to keep the pressure on Barca.

He had already hit a double along with a Diego Costa header to put Atletico out of sight by half-time, his second smashed on the half-volley direct from a throw-in.

He completed his hat-trick with a second-half penalty before hitting two more to make him the first player to hit five in a La Liga game since Fernando Morientes for Real Madrid against Las Palmas in 2002.

It was Atletico's eighth straight home win of the campaign.

A hapless looking Deportivo side remain bottom of the table on 11 points, level with Espanyol.

Also on Sunday, Levante thrashed Mallorca 4-0 with goals from Obafemi Martins, David Navarro, Ruben Garcia and Vicente Iborra to move into sixth position.

A first-half header from Aritz Aduriz, his ninth of the season, was enough for Athletic to edge a competitive encounter with Celta Vigo.

On Saturday Real Madrid kept in touch with a 3-2 win at Valladolid, but remain five points behind Atletico in third.

Google, Facebook ask court to reject patents on abstract ideas

As patent spats continue to command much of the tech world's attention and corporate resources, a group of prominent companies is taking a stand against a practice it sees as hobbling innovation.

Google, Facebook, Zynga and five other tech giants filed an amicus brief with the U.S. State Court of Appeals for the Federal Circuit on Friday, asking the court to reject the patents central to a lawsuit between two financial institutions. CLS Bank sued Alice Corp. for infringing on four patents covering a computerized method of having a third-party hold funds in escrow on behalf of two other contracting parties.

The 37-page brief (see below), also signed by Dell, Intuit, Homeaway, Rackspace, and Red Hat, argues that combining phrases such as "on a computer" or "over the Internet" with an abstract idea doesn't deserve a patent. The brief said the issue was "critically important in the high-tech context" and that granting patents stymie innovation:

Many computer-related patent claims just describe an abstract idea at a high level of generality and say to perform it on a computer or over the Internet. Such barebones claims grant exclusive rights over the abstract idea itself, with no limit on how the idea is implemented. Granting patent protection for such claims would impair, not promote, innovation by conferring exclusive rights on those who have not meaningfully innovated, and thereby penalizing those that do later innovate by blocking or taxing their applications of the abstract idea.

Calling abstract patents a "plague in the high-tech sector," the brief concludes that, "It is easy to think of abstract ideas about what a computer or website should do, but the difficult, valuable, and often groundbreaking part of online innovation comes next: designing, analyzing, building, and deploying the interface, software, and hardware to implement that idea in a way that is useful in daily life. Simply put, ideas are much easier to come by than working implementations."

The brief comes as companies grapple with a rash of lawsuits based on patents that are secured for the purpose of extracting licensing fees from other companies rather than making products based on the patents. A study released earlier this year found that patent infringement lawsuits are on the rise, costing U.S. companies $29 billion in 2011.

The explosion in patent lawsuits, especially in the software and pharmaceutical industries, led one judge presiding over high-profile cases to declare that "patent protection is on the whole excessive and that major reforms are necessary."

Plants Grow Fine Without Gravity

When researchers sent plants to the International Space Station in 2010, the flora wasn't meant to be decorative. Instead, the seeds of these small, white flowers—called Arabidopsis thaliana—were the subject of an experiment to study how plant roots developed in a weightless environment.

Gravity is an important influence on root growth, but the scientists found that their space plants didn't need it to flourish. The research team from the University of Florida in Gainesville thinks this ability is related to a plant's inherent ability to orient itself as it grows. Seeds germinated on the International Space Station sprouted roots that behaved like they would on Earth—growing away from the seed to seek nutrients and water in exactly the same pattern observed with gravity. (Related: "Beyond Gravity.")

Since the flowers were orbiting some 220 miles (350 kilometers) above the Earth at the time, the NASA-funded experiment suggests that plants still retain an earthy instinct when they don't have gravity as a guide.

"The role of gravity in plant growth and development in terrestrial environments is well understood," said plant geneticist and study co-author Anna-Lisa Paul, with the University of Florida in Gainesville. "What is less well understood is how plants respond when you remove gravity." (See a video about plant growth.)

The new study revealed that "features of plant growth we thought were a result of gravity acting on plant cells and organs do not actually require gravity," she added.

Paul and her collaborator Robert Ferl, a plant biologist at the University of Florida in Gainesville, monitored their plants from the Kennedy Space Center in Florida using images sent from the space station every six hours.

Root Growth

Grown on a nutrient-rich gel in clear petri plates, the space flowers showed familiar root growth patterns such as "skewing," where roots slant progressively as they branch out.

"When we saw the first pictures come back from orbit and saw that we had most of the skewing phenomenon we were quite surprised," Paul said.

Researchers have always thought that skewing was the result of gravity's effects on how the root tip interacts with the surfaces it encounters as it grows, she added. But Paul and Ferl suspect that in the absence of gravity, other cues take over that enable the plant to direct its roots away from the seed and light-seeking shoot. Those cues could include moisture, nutrients, and light avoidance.

"Bottom line is that although plants 'know' that they are in a novel environment, they ultimately do just fine," Paul said.

The finding further boosts the prospect of cultivating food plants in space and, eventually, on other planets.

"There's really no impediment to growing plants in microgravity, such as on a long-term mission to Mars, or in reduced-gravity environments such as in specialized greenhouses on Mars or the moon," Paul said. (Related: "Alien Trees Would Bloom Black on Worlds With Double Stars.")

The study findings appear in the latest issue of the journal BMC Plant Biology.

Banda Superstar Jenni Rivera's Plane Missing

Mexican officials have confirmed the disappearance of a private jet carrying regional Mexican music superstar Jenni Rivera that took off from the northern Mexican city of Monterrey at 3:15 a.m. local time on Sunday and fell off the radar 10 minutes (or 62 miles) after take-off.

The Learjet 25 jet is believed to have been carrying seven people – five passengers and two pilots. It was headed for Toluca International Aiport, located outside of Mexico City, where it was meant to arrive at 4:40 a.m. An official search for the jet was initiated at sunrise.

Rivera's publicist Arturo Rivera is believed to have been on that flight. His most recent tweets are of photos from Rivera's concert in Monterrey on Saturday night.

The Mexican American singer's most recent tweet is a re-tweet of what appears to be a fan's message.

Rivera was due in Toluca this evening for the taping of a Mexican TV show, La Voz.

Known as La Diva de la Banda and beloved by fans on both sides of the border, Rivera, 43, has had a groundbreaking career in regional Mexican music, selling some 15 million records. Among her many feats in a male-dominated genre, she made history in September 2011 when she sold out the Staples Center in Los Angeles, the first female regional Mexican artist to do so. Her reality show on mun2, I Love Jenni, is one of the network's highest rated shows. Rivera made her film debut at the 2012 Sundance Film Festival in the indie family drama Filly Brown, due in theaters in January 2013.

The Long Beach, Calif.-born singer's personal life has often called for as much attention as her career. A mother of five, Rivera had filed for divorce from baseball player Esteban Loaiza in October after two years of marriage, citing "irreconcilable differences." Soon after, rumors of an affair between Loaiza and Rivera's own daughter Chiquis surfaced, which Chiquis addressed on Twitter in October by saying, "I would NEVER do that, Ever! That's a horrible accusation."

The search for Rivera's jet continues. This is a developing story.
