Doha summit launches climate damage aid

The latest summit to stop climate change, held in Doha, Qatar, over the past two weeks has been roundly slammed. Little was agreed to curb greenhouse gas emissions and the latest modelling, carried out by the Climate Action Tracker consortium shows global averages temperatures are still set to rise by at least 3 °C above pre-industrial levels.

There was one breakthrough: developing countries won a promise from developed ones that they would compensate them for losses and damage caused by climate change. The deal offers the promise of large amounts of climate aid. But first, science will have to catch up with politics.

All countries will suffer from climate change. There will be consequences even if humanity slashed its emissions and stopped temperatures rising more than 2 °C above pre-industrial levels, the stated goal of the UN negotiations. In actual fact, with emissions rising faster than ever, a 3 or 4 °C rise is likely this century.

The consequences will be manifold. Deserts will spread and lethal heatwaves become more frequent. Changes in rainfall will bring droughts, floods and storms, while rising seas will swamp low-lying areas, obliterating valuable territory. Food production will fall.

Before Doha kicked off, the charities ActionAid, CARE International and WWF released a report arguing that rich countries should compensate poor countries for such damages. Tackling the Limits to Adaptation points out that climate change will cost countries dearly, both economically and in less tangible ways such as the loss of indigenous cultures.

Two-pronged approach

So far, climate negotiations have taken a two-pronged approach to the problem. On the one hand, they have sought to create incentives or imperatives to cut emissions. On the other, they have established a pot of money for poor countries to pay for measures that will help them fend off the unavoidable consequences of climate change – such as sea walls and irrigation systems.

That, according to some, leaves a third element missing. Helping those who suffer the consequences of climate change is a moral obligation and must be part of any treaty on climate change, says Niklas Höhne of renewable energy consultancy Ecofys. The idea of climate compensation has been around since the early 1990s, when the United Nations Framework Convention on Climate Change was negotiated.

In Doha, a coalition including China, the Alliance of Small Island States and the G77 group of developing countries pushed for it to revived.

They proposed a scheme that would decide when countries had suffered climate harms, and compensate them. It would be a form of insurance, and the greatest international aid scheme ever. The idea gained momentum after Typhoon Bopha struck the Philippines last week, and that country's negotiator Naderev "Yeb" Saño broke down in tears during a speech. And, although developed nations had little incentive to agree, the conference concluded with a promise to set something up next year.

Compensation poses a fundamental challenge to climate science, which still struggles to work out if trends and events are caused by greenhouse gases or would have happened anyway. "We can't say that an individual event was caused by climate change," says Nigel Arnell of the University of Reading, UK. "What we can do is say that the chance of it happening was greater."

Systematic tests

Some climatologists are now running systematic tests to decide whether extreme weather events are caused by climate change. They run climate models with and without humanity's emissions. If the odds of a particular event are different, it suggests it was at least partially driven by emissions. By this measure, the 2003 European heatwave and 2011 Texas drought were both made more likely by human emissions.

But this science is in its infancy. We can confidently attribute large-scale trends and temperature changes, says Kevin Trenberth of the National Center for Atmospheric Research in Boulder, Colorado. But changes in rainfall, and short-term events like hurricanes, are harder because we do not really understand them. Trenberth speculates that superstorm Sandy would not have flooded the New York subways without climate change, but says it's not possible to prove.

Arnell says that might prove unworkable. Gradual changes – such as rising sea levels, melting glaciers and ocean acidification – are easy to attribute to climate change but their consequences difficult to cost; sudden events are easy to cost but difficult to attribute.

There may be another possibility. Rather than examining individual events, climate models could predict the extra climate-related costs each country would experience, allowing regular payouts. "That would be a way round it," says Arnell. Delegates at next year's conference will have to consider these questions.

Positive step

Harjeet Singh of ActionAid in New Delhi, India, calls the Doha deal "a positive step forward". But it is only an agreement in principle: no money was committed, and even a promise to do so in the future was left out of the final text. Edward Davey, the UK's secretary of state for energy and climate change, said it was "far too early" to talk about committing money. "We aren't saying there should be compensation," he said.

Singh says the developed world would save money by cutting emissions now, rather than letting temperatures rise and then paying compensation. Small island states were keen to get an agreement on loss and damage because emissions cuts are going so slowly, making dangerous climate change almost certain. The Doha agreement is a first step towards dealing with the consequences of that failure.

On 'other business'

Aside from agreeing to make compensation available for loss and damage, the Doha summit achieved little. Nearly two decades ago, the world's governments set out to agree a binding deal to cut greenhouse gas emissions. Doha included some baby steps towards a deal in 2015, but that is not guaranteed and in any case will come too late to stop dangerous climate change. Only Lebanon and the Dominican Republic made new emissions pledges.

The talks were bogged down in rows over financing. In a deal that was separate to the adaptation fund, developed countries had promised in 2009 to deliver $100 billion a year by 2020 to help poor nations prepare for climate change. Between 2009 and 2012 they allocated $10 billion a year. In Doha they refused to say how they would scale that up, simply promising to "continue" – leaving developing countries unsure if or when they would get more.

The Kyoto protocol was renewed until 2020, but its global effect is likely to be limited. Its value is partly symbolic, to show that binding agreements can be reached, and as one of many small and medium-scale projects to cut emissions.

Twitter adds Instagram-style photo features

SAN FRANCISCO: Twitter on Monday added Instagram-style smartphone photo sharing features after the Facebook-owned service made it impossible for Internet users to integrate its images into tweets.

"Starting today, you'll be able to edit and refine photos, right from Twitter," the globally popular one-to-many messaging service said in a blog post.

"Every day, millions of people come to Twitter to connect with the things they care about and find out what's happening around the world," it added.

"As one of the most compelling forms of self-expression, photos have long been an important part of these experiences."

Twitter said its partner Aviary is powering "filters" and other effects for images using the latest Twitter applications for Apple iPhones or smartphones running on Google-backed Android software.

A social media feud between Twitter and Instagram escalated over the weekend as the popular smartphone photo-sharing service made it impossible for Internet users to view its images in "tweeted" messages.

Instagram, which has some 100 million users, is seeking to route photo viewers to its own website, where it has the potential to make money from ads or other mechanisms, instead of letting Twitter get the benefits.

Previously, Instagram pictures shared in messages tweeted from smartphones could be viewed unaltered at Twitter.

Twitter indicated in a status update Sunday that Instagram had "disabled photo integration with Twitter" and that "as a result, photos are no longer appearing in Tweets or user photo galleries."

"While tweeting links to Instagram photos is still possible, you can no longer view the photos on Twitter, as was previously the case," Twitter said.

Last week, Instagram had made it more difficult to view pictures in tweets, with the images cropped from the posts called Twitter Cards. By Sunday, the images were no longer viewable.

The moves escalated the battle between the smartphone app Instagram, which was acquired by Facebook this year, and the popular message service Twitter.

Instagram co-founder Kevin Systrom told a Paris conference last week that the move was part of a shift by the photo app to direct more users to the Instagram site.

Instagram rose to stardom with the help of Twitter, but has distanced itself from the messaging service since being acquired by leading social network Facebook.

Facebook completed its acquisition of Instagram in September. The original price was pegged at US$1 billion but the final value was less because of a decline in the social network's share price.

Instagram last month was given a Facebook spin with the roll-out of online profiles that let people showcase themselves and photos they have taken with the smartphone application.

People can share their profiles with whomever they wish, as well as "follow" other Instagram users, commenting on or expressing "likes" for pictures.

A distinctive feature of Instagram is that it allows users sharing smartphone snaps to enhance them with image filters for artistic effects such as mimicking historic types of film.

It's still a mystery where John McAfee will eventually land, but his life story is destined for the small screen.

Currently in custody in Guatemala and fighting deportation efforts that could return him to Belize to face questions about a murder, the antivirus-software pioneer has signed a deal that gives the rights to his life story to a Montreal-based TV producer.

The TV production company Impact Future Media said today it has secured the exclusive intellectual property rights to the former fugitive's story, a project tentatively titled "Running in the Background: The True Story of John McAfee."

"Mr. McAfee has entrusted us with his life story, and that is a responsibility we take very seriously," François Garcia, CEO and cofounder of Impact Future Media, said in a statement. "We will work tirelessly to make certain that his story is shared with the proper industry partners."

McAfee, 67, offered a "most heartfelt thank-you" to Impact Future Media for taking on the project.

"Their dedication to the truth is very uncommon in the world we live in today," McAfee said in the company's press release. "I am now, and will always be grateful to their organizations."

McAfee was arrested Wednesday by Guatemalan police after crossing into the country early last week to seek asylum, a request that has since been denied. McAfee had been on the run from police in neighboring Belize since November 12, when his neighbor Gregory Faull, a contractor and restaurant owner, was discovered with a bullet in his head.

McAfee, who claims he is being wrongfully persecuted by officials in Belize, has filed a trio of appeals with the Guatemalan government to avoid deportation and has also said he would like to return to the United States.

"My goal is to get back to America as soon as possible," McAfee told Reuters. "I wish I could just pack my bags and go to Miami."

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.

Guilty Verdict in Lottery Winner's Murder

DeeDee Moore, the Tampa woman accused of swindling and then killing lottery winner Abraham Shakespeare, was found guilty today of first degree murder and other charges, after she declined to take the stand and the defense rested without calling a single witness.

In addition to the murder charge, Moore was also found guilty of possessing and discharging a firearm resulting in death. Prosecutors did not pursue the death penalty in the case, and Moore was sentenced to life in prison without parole.

"After trial and listening to all of this over two weeks, words that were said cool, calculated, manipulated. Abraham Shakespeare was your prey and victim. Money was the route of evil you brought to Abraham. You are sentenced to life in prison you shall not be elegible for parole," Judge Emmet Battles said.

Jurors deliberated for more than three hours Monday before delivering their verdict.

Prosecutors argued that Moore, 40, befriended Shakespeare before he vanished in April 2009 after he'd won $30 million in the Florida lottery. After Shakespeare had given away most of his money to people who simply asked for it, Moore agreed to manage the little he had left, but instead, prosecutors said, stole his winnings and killed him.

During a dramatic trial Moore has broken down in tears several times, and at one point said that she went into anaphylactic shock while in custody after taking the drug Bactrim when she was having problems with cuts on her ankles from being cuffed every day.

Early today the defense announced it would rest its case without calling any witnesses. Moore did not testify during her trial.

Dee Dee Moore Trial: Woman Accused of Murdering Lottery Winner Watch Video

"There is no witness that can say she ever admitted to doing the killing or participating as a principle in helping anyone else do the killing," Moore's defense attorney Byron Hileman said today.

In the courtroom this morning, Moore's friend, former inmate Rose Condora was accused of threatening witnesses by Tampa Judge Emmett Battles, and was thrown out of the courtroom.

Authorities say Shakespeare, 47, was shot twice in the chest by a .38-caliber pistol sometime in April 2009. He wasn't reported missing until November 2009. His body was found under a slab of cement in a backyard in January 2010.

Polk County authorities claim Moore offered someone a $200,000 house in exchange for reporting a false sighting of Shakespeare. She also allegedly sent the victim's son $5,000 in cash for his birthday, and used the victim's cellphone to send text messages purportedly from him.

Shakespeare's mother, Elizabeth Walker, also testified that Moore tried to hide that her son was missing, and said that he had AIDS.

Sentorria Butler, Shakespeare's ex-girlfriend and the mother of his child, also testified. Butler told the court last week that Moore is a divisive and manipulative woman who told her Shakespeare "ran off with the lady from the bank."

During the trial, jurors also watched a Walmart surveillance video that the prosecution said links Moore to Shakespeare's killing. The footage shows Moore making a $104 cash purchase of gloves, duct tape, plastic sheeting and other items detectives later found close to where Shakespeare's body was buried.

Jurors hearing the case also heard a rambling two-page letter that witness Greg Smith, a police informant who was a former friend of Shakespeare and supposed friend of Moore, says Moore allegedly forged while at a Comfort Inn & Suites in Lakeland, Fla.

The letter was meant to appear to be from Shakespeare, prosecutors said. They say the letter was a ruse to convince Shakespeare's mother that he was still alive. Moore attempted to cover her tracks while it was written, according to prosecutors.

During the trial, jurors had to be accompanied by a security escort into the courtroom after they told the judge Smith and Shakespeare's family and friends were making them feel uncomfortable outside the courthouse. None of the jurors had to be excused by the judge.

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.

Fire breaks out at Bendemeer Road; elderly sent to hospital

SINGAPORE: A fire broke out in a flat at block 31 Bendemeer Road on Sunday night.

The Singapore Civil Defence Force said it received a call at just past 9:00pm. It despatched two fire engines, a Red Rhino, an ambulance and a support vehicle.

When officers arrived at the scene they saw white smoke coming from a ninth floor unit. An elderly woman was found standing near the front metal grille door of the unit.

Fire fighters used rescue tools to pry open the grille. The elderly woman complained of breathing difficulties. She was sent to the Singapore General Hospital.

The fire was confined to the stove area in the kitchen.

The SCDF has issued these fire safety tips - do not leave cooking unattended; turn off all cooking appliances and unplug them when not in use; avoid wearing clothes with long loose sleeves when working near heat sources; never place or store combustible items/ materials (for eg. paper etc) near heat sources; do not overload electrical outlets (for eg. do not overload multi-plugs); check for broken wires and exposed wirings; if any are found, replace them immediately; do not throw burning embers (for eg. hot charcoal) into rubbish chutes without fully extinguishing them first; and keep matches, lighters and candles away from children.

White House joins Pinterest

President Obama is increasing his administration's social media presence by moving the White House on to Pinterest.

While the president already has a Pinterest account in his own name, used primarily to support his re-election campaign, the White House account will be used to post images and information relating to life inside 1600 Pennsylvania Avenue.

"It's the 'People's House,'" First Lady Michelle Obama, said in a WhiteHouse.gov blog post. "It's a place that is steeped in history, but it's also a place where everyone should feel welcome. And that's why my husband and I have made it our mission to open up the house to as many people as we can."

The White House's first pinboard will debut on December 17, the date of the president's holiday social.

Obama is a dedicated social-networking buff; in addition to Pinterest, he has accounts with Twitter, Facebook, YouTube, Instagram, Tumblr, Google+, and Myspace. He recently used his Twitter account to drum up support for his tax plan, and a tweet sent by his account after being re-elected quickly became the most popular tweet ever, with more than 800,000 retweets.

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.

Remains of Banda Superstar Jenni Rivera's Jet Reported Found

UPDATED: Multiple reports, including one from Gerardo Ruiz Esparza, Mexico's Secretary of Communications and Transports, claim that the remains of the private jet carrying Jenni Rivera have been found, with no survivors. Rivera, 43, was one of seven passengers.

Rivera's parents are believed to be en route to Mexico. Her brother, fellow singer Lupillo Rivera, and eldest daughter Chiquis have still not made any statements.

Celebrity reactions on Twitter have poured in since news of the disappearance of Rivera's jet, including Paulina Rubio (who was set to co-host the Mexican edition of The Voice with Rivera) William Levy, Joan Sebastian, Ricky Martin, and others.

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 and her make-up artist Jacob Yebale are believed to have been on that flight. Their 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. Televisa has canceled tonight's show given Rivera's disappearance.

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."
