Gunman 'Tentatively' Identified in Oregon Shooting













A masked gunman who opened fire in the crowded Clackamas Town Center mall in suburban Portland, Ore., killing two individuals before killing himself, has been "tentatively" identified by police, though they have not yet released his name.


The shooter, wearing a white hockey mask, black clothing, and a bullet proof vest, tore through the mall around 3:30 p.m. Tuesday, entering through a Macy's store and proceeding to the food court and public areas spraying bullets, according to witness reports.


Police have not released the names of the deceased. Clackamas County Sheriff's Department Lt. James Rhodes said authorities are in the process of notifying victims' families.


The injured victim has been transported to a local hospital, according to Clackamas County Sheriff Craig Roberts.

Nadia Telguz, who said she was a friend of the injured victim, told ABC News affiliate KATU-TV in Portland that the woman was expected to recover.


"My friend's sister got shot," Teleguz told KATU. "She's on her way to (Oregon Health and Science University hospital). They're saying she got shot in her side and so it's not life-threatening, so she'll be OK."


Witnesses from the shooting rampage said that a young man who appeared to be a teenager ran through the upper level of Macy's to the mall food court, firing multiple shots, one right after the other, with what is believed to be a black, semi-automatic rifle.

More than 10,000 shoppers were at the mall during the day, police said. Roberts said that officers responded to the scene of the shooting within minutes, and four SWAT teams swept the 1.4 million-square-foot building searching for the shooter. He was eventually found dead, an apparent suicide.


"I can confirm the shooter is dead of an apparent self-inflicted gunshot wound," Rhodes said. "By all accounts there were no rounds fired by law enforcement today in the mall."


Roberts said more than 100 law enforcement officers responded to the shooting, and at least four local agencies were working on the investigation, including the FBI and Bureau of Alcohol, Tobacco and Firearms, which is working to trace the shooter's weapon.

"For all of us, the mall is supposed to be a place where we can take our families, especially during the holiday season," Roberts said. "Things like this are not supposed to happen."


Roberts also said that shoppers, including two emergency room nurses and one physician who happened to be at the mall, provided medical assistance to victims who had been shot. Other shoppers helped escort individuals out of the mall and out of harm's way, he said.


"There were a huge amount of people running in different directions, and it was chaos for a lot of citizens, but true heroes were stepping up in this time of high stress," Roberts said. "E.R. nurses on the scene were providing medical care to those injured, a physician on the scene was helping provide care to the wounded."


Mall shopper Daniel Martinez told KATU that he had just sat down at a Jamba Juice inside the mall when he heard rapid gunfire. He turned and saw the masked gunman, dressed in all black, about 10 feet away from him.


"I just saw him (the gunman) and thought, 'I need to go somewhere,'" Martinez said. "It was so fast, and at that time, everyone was moving around."


Martinez said he ran to the nearest clothing store. As he ran, he motioned for another woman to follow; several others ran to the store as well, hiding in a fitting room. They stayed there for an hour and a half until SWAT teams told them it was safe to leave the mall.

Twitter vs. Instagram in a knock-down, drag out filters fight




With one bold step Monday, Twitter took the photo filtering fight directly to Instagram.


Until yesterday, Instagram was the undisputed leader when it comes to mobile photo filtering and sharing. But with its release of a new version of its mobile app that enables filters, Twitter has launched a very credible challenge to the crown.



To be sure, Instagram has a massive lead, and a very passionate community. But Twitter has a nine-figure user base, and now that it is offering filters -- albeit just eight, while Instagram has 18 free filters -- it can begin to chip away at its competitor's lead.


There's only one way to decide whose filters are best, though, and that's to compare them side by side. With that in mind, CNET took a single photograph and applied each of Twitter's and Instagram's free filters. Only you can decide which is best.


Which filter do you think is best? Please leave your thoughts in the comments section.

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.

SEAL Killed in Rescue Mission Identified













The Pentagon has identified Petty Officer 1st Class Nicolas Checque as the Navy SEAL who died of injuries sustained in the successful rescue of an American doctor from the Taliban over the weekend.


Checque, who hailed from Monroeville, Pa., died of "combat related injuries," according to a Pentagon release. Though the release only said Checque was assigned to "an East Coast-based Naval Special Warfare unit," ABC News previously reported the fallen servicemember was a part of the Navy's elite SEAL Team 6, the same unit that killed Osama bin Laden.


Checque, 28, sustained his mortal injuries while on a nighttime mission Saturday to free Dr. Dilip Joseph, an American doctor who worked for an non-governmental organization based in Kabul. Joseph was kidnapped by the Taliban earlier this month and American officials believed he was in imminent danger.

Joseph's family released a statement thanking the U.S. government and military for the operation and offering their condolences to Checque's family.


"We could not be more grateful for that soldier's heroism and for the bravery of all involved in the mission to bring Dilip home," the statement said.


Before Checque was identified publicly, Defense Secretary Leon Panetta said Sunday he was "deeply saddened" to learn one of the servicemen had died.


"The special operators who conducted this raid knew they were putting their lives on the line to free a fellow American from the enemy's grip. They put the safety of another American ahead of their own, as so many of our brave warriors do every day and every night. In this fallen hero, and all of our special operators, Americans see the highest ideals of citizenship, sacrifice and service upheld. The torch of freedom burns brighter because of them," Panetta said.


President Obama also praised the Special Operations force for their bravery.


"Yesterday, our special operators in Afghanistan rescued an American citizen in a mission that was characteristic of the extraordinary courage, skill and patriotism that our troops show every day," he said Sunday.

Why the world is arguing over who runs the internet






















The ethos of freedom from control that underpins the web is facing its first serious test, says Wendy M. Grossman






















WHO runs the internet? For the past 30 years, pretty much no one. Some governments might call this a bug, but to the engineers who designed the protocols, standards, naming and numbering systems of the internet, it's a feature.












The goal was to build a network that could withstand damage and would enable the sharing of information. In that, they clearly succeeded - hence the oft-repeated line from John Gilmore, founder of digital rights group Electronic Frontier Foundation: "The internet interprets censorship as damage and routes around it." These pioneers also created a robust platform on which a guy in a dorm room could build a business that serves a billion people.












But perhaps not for much longer. This week, 2000 people have gathered for the World Conference on International Telecommunications (WCIT) in Dubai in the United Arab Emirates to discuss, in part, whether they should be in charge.












The stated goal of the Dubai meeting is to update the obscure International Telecommunications Regulations (ITRs), last revised in 1988. These relate to the way international telecom providers operate. In charge of this process is the International Telecommunications Union (ITU), an agency set up in 1865 with the advent of the telegraph. Its $200 million annual budget is mainly funded by membership fees from 193 countries and about 700 companies. Civil society groups are only represented if their governments choose to include them in their delegations. Some do, some don't. This is part of the controversy: the WCIT is effectively a closed shop.












Vinton Cerf, Google's chief internet evangelist and co-inventor of the TCP/IP internet protocols, wrote in May that decisions in Dubai "have the potential to put government handcuffs on the net".












The need to update the ITRs isn't surprising. Consider what has happened since 1988: the internet, Wi-Fi, broadband, successive generations of mobile telephony, international data centres, cloud computing. In 1988, there were a handful of telephone companies - now there are thousands of relevant providers.












Controversy surrounding the WCIT gathering has been building for months. In May, 30 digital and human rights organisations from all over the world wrote to the ITU with three demands: first, that it publicly release all preparatory documents and proposals; second, that it open the process to civil society; and third that it ask member states to solicit input from all interested groups at national level. In June, two academics at George Mason University in Virginia - Jerry Brito and Eli Dourado - set up the WCITLeaks site, soliciting copies of the WCIT documents and posting those they received. There were still gaps in late November when .nxt, a consultancy firm and ITU member, broke ranks and posted the lot on its own site.












The issue entered the mainstream when Greenpeace and the International Trade Union Confederation (ITUC) launched the Stop the Net Grab campaign, demanding that the WCIT be opened up to outsiders. At the launch of the campaign on 12 November, Sharan Burrow, general secretary of the ITUC, pledged to fight for as long it took to ensure an open debate on whether regulation was necessary. "We will stay the distance," she said.












This marks the first time that such large, experienced, international campaigners, whose primary work has nothing to do with the internet, have sought to protect its freedoms. This shows how fundamental a technology the internet has become.












A week later, the European parliament passed a resolution stating that the ITU was "not the appropriate body to assert regulatory authority over either internet governance or internet traffic flows", opposing any efforts to extend the ITU's scope and insisting that its human rights principles took precedence. The US has always argued against regulation.












Efforts by ITU secretary general Hamadoun Touré to spread calm have largely failed. In October, he argued that extending the internet to the two-thirds of the world currently without access required the UN's leadership. Elsewhere, he has repeatedly claimed that the more radical proposals on the table in Dubai would not be passed because they would require consensus.












These proposals raise two key fears for digital rights campaigners. The first concerns censorship and surveillance: some nations, such as Russia, favour regulation as a way to control or monitor content transiting their networks.












The second is financial. Traditional international calls attract settlement fees, which are paid by the operator in the originating country to the operator in the terminating country for completing the call. On the internet, everyone simply pays for their part of the network, and ISPs do not charge to carry each other's traffic. These arrangements underpin network neutrality, the principle that all packets are delivered equally on a "best efforts" basis. Regulation to bring in settlement costs would end today's free-for-all, in which anyone may set up a site without permission. Small wonder that Google is one of the most vocal anti-WCIT campaigners.












How worried should we be? Well, the ITU cannot enforce its decisions, but, as was pointed out at the Stop the Net Grab launch, the system is so thoroughly interconnected that there is plenty of scope for damage if a few countries decide to adopt any new regulatory measures.












This is why so many people want to be represented in a dull, lengthy process run by an organisation that may be outdated to revise regulations that can be safely ignored. If you're not in the room you can't stop the bad stuff.

Greece extends debt buyback to Tuesday






ATHENS: Greece announced it had extended until Tuesday a debt buyback offer, the success of which is key for it to receive bailout funding from the EU and IMF without which it could soon go bankrupt.

"We have decided to extend the invitation to offer designated securities for exchange to 11 December 2012," the head of Greece's PDMA debt management agency, Stelios Papadopoulos, said in a statement on Monday.

Private holders of Greek sovereign bonds originally had to submit by Friday their offers to participate in the buyback, which offered them 32.2 to 40.1 percent of the face value of the securities.

The PDMA statement said they now had until 1200 GMT on Tuesday to submit bids to participate in the buyback, which aims to cut Greece's debt by around 20 billion euros (US$26 billion) and is vital to qualify for more financial aid from the European Union and International Monetary Fund.

The head of the PDMA warned that any future offers to buy back debt may not be as advantageous to investors.

"Future measures may not involve an opportunity to exit investments (Greek sovereign bonds) at the levels offered for this buyback," Papadopoulos said.

The IMF and the eurozone have agreed to release 43.7 billion euros in rescue loans in four instalments to enable Greece to avoid bankruptcy provided Athens carries out the bond buyback.

Five lies your TV salesperson will tell you



Using the time-honored tactics of obfuscation, misdirection, and a little bit of fear, the people who try to sell you TVs can hit you with some heavy-duty lies.


Now this isn't to say that all TV sales people are bad, nor that any necessarily do this out of malice (there's plenty of misinformation out there confused as truth). But when it's your dollar on the line, being prepared with some facts can only be a good thing.



For a primer on all the jargon, check out "TV tech explainer: Every HDTV technology decoded."


'This TV has a million-to-one contrast ratio.'
No, it doesn't. Every TV manufacturer lies about contrast ratio. Not a single one is remotely accurate. So it's impossible to prescribe an exact number to any TV given only the manufacturers data. The fact is, plasmas have better native contrast ratios than LCDs (LED or otherwise). There are three local-dimming LED LCDs on the market this year (Elite by Sharp, Sony HX950, and LG LM9600), and they're all extremely expensive. These offer similar contrast ratios than the best plasmas, though not exactly. For more info, check out "Contrast ratio (or how every TV manufacturer lies to you)."


'This TV has better sound.'
You know what, let's say they're right. Let's say TV A has better sound than TV B. The fact is, no TV sounds good. So all they're really saying is, "This TV sounds less bad than this other TV."


The thinness that we all love in flat-panel TVs means the speaker drivers by their very nature have to be very small. Small drivers can't do much to create sound waves.


The wiser salespeople will direct you towards a sound bar or other home audio system. This is definitely where you should spend a few dollars. Pretty much every sound bar will sound better than the TV speakers, and the better sound bars actually sound pretty good.


Check out CNET's page on the best home audio and best sound bars.



'TVs break all the time. You need an extended warranty.'
Another example of this is "I see TVs come in for repair all the time." From a rhetorical standpoint, this is a rather brilliant argument. This person works at the store. They see lots of TVs coming in for repair. So as an "authority," this seems a valid point.


Except, it isn't.


What the salesperson isn't seeing, is all the TVs that don't come in for repair. Which is most of them. Flat-panel TVs are very reliable, so an extended warranty is a largely a waste of money.


'LED TVs have the best picture quality.'
Nope. First of all, there's no such thing as an "LED TV." Every
LED TV is just a standard LCD TV that uses LEDs to create light instead of the "old-fashioned" cold-cathode fluorescent lamps (CCFL). LCDs have their positives, like light output and lower energy consumption, but when it comes to a direct picture quality comparison, plasmas have better black levels, better contrast ratios, and better viewing angles (for those not sitting directly in front of the TV). For example, four of the five TVs CNET picked for best picture quality are plasmas (the one LED LCD is also the most expensive TV you can buy per-screen-inch).


There's more to it than that, as I lay out in "Why LED does not mean a better picture" and "LED LCD vs. plasma vs. LCD."


'If you want the best picture and sound, you need the best HDMI cable.'
This is the one that annoys me the most, and I've written four articles about it for CNET alone. This is the one that eliminates any guilt I have impugning the good name of some hard-working salespeople. There is no picture or sound quality difference between any HDMI cable. None. At all. So if you spend $3 or $300, the image and sound will be 100 percent exactly the same.


I could talk about this forever, and indeed I have. Check out "Why all HDMI cables are the same,"
"Why all HDMI cables are the same, Part 2,"
"Still more reasons why all HDMI cable are the same," and the "HDMI cable buying guide."


Bottom line



It is difficult to get a man to understand something, when his salary depends upon his not understanding it! -- Upton Sinclair



A commenter on one of the HDMI articles posted the above quote, and it's perfect. But look, be polite. Don't waste someone's time. This goes for both sides. They're just trying to make a living, you're just trying to keep as much of your living as possible. When I sold electronics at Circuit City, I was given all sorts of information, presented as truth, to tell customers. Much of which I know now to be false, or at least "truth adjacent." But as an 18-year-old, long haired (yep, believe it), wannabe guitar god, I didn't know any better. So give the poor guy or gal the benefit of the doubt that they're not knowingly lying to you.



Except for that HDMI cable stuff; man that bugs me.



How about you? Been told any doozys?




Got a question for Geoff? Send him an e-mail! If it's witty, amusing, and/or a good question, you may just see it in a post just like this one. No, he won't tell you which TV to buy. Yes, he'll probably truncate and/or clean up your e-mail. You can also send him a message on Twitter: @TechWriterGeoff.

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.

Fiscal Cliff Talks: Boehner, Obama Meet Face-to-Face













For the first time in more than three weeks, President Obama and House Speaker John Boehner met face-to-face today at the White House to talk about avoiding the fiscal cliff.


White House Principal Deputy Press Secretary Josh Earnest would offer no details saying only, "The lines of communication remain open."


Erskine Bowles, the co-creator of a debt reducing plan, who was pessimistic a couple weeks ago, said he likes what he's hearing.


"Any time you have two guys in there tangoing, you have a chance to get it done," Bowles said on CBS's "Face the Nation."


The White House afternoon talks, conducted without cameras or any announcement until they were over, came as some Republicans were showing more flexibility about approving higher tax rates for the wealthy, one of the president's demands to keep the country from the so-called fiscal cliff -- a mixture of across-the-board tax increases and spending cuts that many economists say would send the country back into recession.

Fiscal Cliff Battle: President Obama vs. Speaker John Boehner Watch Video





"Let's face it. He does have the upper hand on taxes. You have to pass something to keep it from happening," Sen. Bob Corker of Tennessee said on "FOX News Sunday."


This comes after the White House moderated one of its demands about tax rate increases for the wealthy.


The administration was demanding the rate return to its former level of 39.6 percent on income above $250,000. The so-called Bush tax cut set that rate at 35 percent. But Friday, Vice President Joe Biden signaled that rate could be negotiable, somewhere between the two.


"So will I accept a tax increase as a part of a deal to actually solve our problems? Yes," said Oklahoma Republican Tom Coburn on ABC's "This Week."


The problems the senator was referring to are the country's entitlement programs. And there was some progress on that front, too.
