Antarctic ice samples: What do they say about global warming?
Antarctic ice core samples, up to 150,000 years old, may help scientists estimate whether it will take 50 years - or 500 years - for the Ross Ice Shelf to collapse at the current rate of climate change.
Scientist Nancy Bertler holds the final section of ice she collected from a half-mile under Antarctica's surface in a laboratory freezer, near Wellington, New Zealand. Antarctica's pristine habitat provides a laboratory for scientists studying the effects of climate change.

They drilled out hundreds of ice cores, each slightly longer and wider than a baseball bat, from the half-mile-thick ice covering Antarctica's Roosevelt Island. The cores, which may total 150,000 years of snowfall, almost didn't survive the boat ride to New Zealand because of a power outage.
Bertler hopes the material will help her estimate how long the Ross Ice Shelf would last under the current rate of climate change before falling apart.
Evidence from the last core her team hauled out needs further study, but it contains material that Bertler said appeared to be marine sediment that formed recently ? at least in geological terms measured in thousands of years.
That would bolster scientists' suspicions that the shelf could collapse again if global temperatures keep rising, triggering a chain of events that could raise sea levels around the world.
"From a scientific point of view, that's really exciting. From a personal point of view, that's really scary," said Bertler, a senior research fellow at the Antarctic Research Centre at the Victoria University of Wellington.
The ice shelf acts as a natural barrier protecting massive amounts of ice in West Antarctica, and that ice also could fall into the ocean if the shelf fell apart. Scientists say West Antarctica holds enough ice to raise sea levels by between 2 meters (6.5 feet) and 6 meters (20 feet) if significant parts of it were to collapse.
Ted Scambos, the lead scientist at the National Snow and Ice Data Center at the University of Colorado, said that even under the worst case scenario he thinks it would take at least 500 years for West Antarctica's ice to melt.
However, he said a discovery of sediment would indicate a significant portion of the ice shelf is under threat of becoming unstable again, and that the implications were "huge."
Bertler hopes the material she recovered will help her to estimate by the end of this year whether it will take 50 years or 500 years for the ice shelf to collapse at the current rate of climate change. Those answers should prove important for policymakers who, she said, may need to decide whether to build sea walls or move populations to higher ground.
Bertler's project is one of scores that take place on Antarctica every Southern Hemisphere summer. To scientists, the continent's pristine habitat offers a unique record of the planet's weather and a laboratory for studying the effects of climate change.
Studies indicate that while the Arctic has suffered what scientists consider to be alarming rates of ice loss in recent years, the Antarctic ice shelf has remained relatively stable despite having have lost ice in recent decades.
Research in Antarctica creates huge logistical and personal challenges.
Bertler's camp on Roosevelt Island is a three-hour flight from the nearest permanent Antarctic outposts, Scott Base and McMurdo Station. The island is surrounded by the Ross Ice Shelf, the world's largest mass of floating ice, covering an area the size of Spain.
Even during the spring and summer months when Bertler's team was working there, the temperature sometimes dropped to minus 25 C (minus 13 F) and there were frequent storms and thick fog.

Roman ring that 'inspired Tolkien' goes on show
LONDON (AP) ? A Roman gold ring that could have inspired J.R.R Tolkien to write "The Hobbit" and "The Lord of the Rings" is going on exhibition in England.
Found in a field in southern England in 1785, the ring is linked to a Roman tablet inscribed with a curse on the thief who stole it.
That tablet was found at the site of a Roman temple dedicated to the god Nodens in Gloucestershire, western England. Tolkien worked on the etymology of the name Nodens in 1929 and visited the temple several times.
Lynn Forest-Hill, education officer for the Tolkien Society, says the exhibition will explore the ring's story and let visitors decide whether it is Tolkien's One Ring.
The exhibition at The Vyne, a historic mansion in southern England, opens Tuesday.

Nvidia: Current-Gen Consoles Barely Have Enough Power to Beat ...
Nvidia's Senior vice president of content and technology, Tony Tamasi says that the next wave of mobile devices (we assume using Nvidia technology) will outperform current generation consoles. He goes so far as to say that current generation systems like the Xbox 360 and PS3 can barely hold an edge over today's Tegra 4 powered devices.
"The PS3 and Xbox 360 are barely more powerful than mobile devices," he told Bit-tech. "The next click of mobile phones will outperform [them]."
Tamasi was wise in not mentioning next-generation consoles in the pipeline like the PS4 and whatever Xbox console Microsoft plans to release.
He also didn't mention Nvidia's upcoming Shield gaming device either...

Conference Delivers Good News for Investing in Energy Stocks ...
Three Key Takeaways if You're Investing in Energy Stocks
? The U.S. is Where It's At: The United States has become one of the best places in the world to conduct business in the oil and gas industry, and companies throughout the globe have raced to the country to take part in the new energy boom.Technologies like fracking that have tapped into vast reserves have erased lingering fears of diminishing energy supplies.
Worries have been replaced by optimism about the abundance of U.S.-produced energy.
According to data from oil field services company Baker Hughes Inc. (NYSE: BHI), oil and gas companies are currently running 1,757 rigs to drill new wells in the U.S. That's far more than the 1,275 wells in operation throughout the rest of the world.
The Energy Information Administration reports the U.S. is expected to average 7.3 million barrels a day of oil production this year, an increase from 6.4 million last year.
Meanwhile, U.S. oil imports have been declining since their 2005 peak. During February, U.S. oil imports averaged an estimated 7.7 million barrels a day, down 1.2 million from the same period a year ago, EIA data shows.
"Unconventional liquid plays helped boost U.S. oil production, which grew by 40% since 2008 - the highest growth in oil output of any country during the period," Yergin explained.
Big economic gains are expected from U.S. shale oil and gas plays.
"We have a strong belief that these shale plays in North America - particularly in the U.S. -
are going to lift the entire U.S. economy by its bootstraps out of its economic malaise and turn the entire economy around over the next five to seven years," said Mark Papa, CEO of Houston-based EOG Resources Inc. (NYSE: EOG).
The Asian nation is drifting from coal to other fuels like nuclear and gas. Currently, coal accounts for 80% of China's power generation. By 2025, the figure is expected to fall to 50% -- 60%.
"We are not going to do away with coal for many decades." Xizhou Zhou, IHS China energy director, said at the conference. But, he added, "We believe the diversification away from coal has already begun."
The U.S. has a competitive edge when it comes to meeting soaring Asian demand for natural gas.
"The U.S. model cannot be easily duplicated. Conditions were right for a shale revolution: Technology and expertise was available, the pipeline infrastructure was very well-developed; the regulatory system was conductive," said Chevron Corp. (NYSE: CVX) Gas and Midstream President Joseph Geagea.
? Russia Could Lose its Place As Top Producer: According to Kuwait Finance House Research, the U.S. will overtake Russia to become the largest oil and gas producing country in 2015.For two decades, Russia has seen "nothing but surprises" in the energy industry, Thane Gustafson, IHS senior director for Russian and Caspian energy, told conference attendees.
But in 2013, the most surprising thing might be that there are no surprises coming out of Russia, Gustafson said: "2013 looks like an unusually quiet year."
That could change in future years, though.
"Russia ... has the largest combined oil and gas reserves, as well as the highest combined production of oil and gas [in the world]. And in our view, its potential has yet to be realized," BP CEO Bob Dudley said in an opening keynote address at CERAWeek.
He sees "enormous scope" for increasing Russia's production through enhanced recovery in Western Siberia and exploration and production in Eastern Siberia and the Yamal Peninsula.
Russia also has the potential to develop its own shale oil, Dudley said.
"What Russia and the U.S. have in common is that each will require energy investment on an epic scale, undertaken by energy partners who are not daunted by the obstacles and have the resources, experience, capability and appetite for the task," he said.

Lee Hi "It's Over" - Kpop Music Mondays - Eat Your Kimchi
DUH LEE DUH LEE EE EE EE! This week we?re talking about Lee Hi?s ?It?s Over? for Kpop Music Monday. It?s awesome! It?s fun! If you haven?t seen it yet, check it out here, and then sing it in your heads incessantly afterwards
Isn?t this video so odd? It?s a really fun concept. A big grumpy jerky teddy bear. Hilarious. Especially when he Rick-James-to-Charlie-Murphy?s all over the shopping cart. The whole video just looked like loads of fun, and it was fun to watch as well. Match that with the super catch chorus and it?s clear why this video would get so many views so fast.
We also like that the cute innocence of this video is actually cute and innocent, and not lolita-esque, like ?I?m cute and innocent oppa but I?m so sexy!? Lee Hi is just cute, and ? though I know she?s in high school ? I swear, she looks like, 9 years old TOPS in this video. See, what struck us about Kpop a while ago is that it seems so much more innocent than Western Pop music, and that?s what?s part of it?s appeal to us and to a lot of other people, but it seems to be losing that more and more lately. This video, though, harkens back to that sweetness, you know?
One theory we tossed around back and forth when we were scripting for Music Monday, but ultimately scrapped, is that Lee Hi might become Korea?s new sweetheart, now that IU seems to have lost that title, from what we read in the news somewhere a while ago after that whole IUnhyuk thingy. We?re not fully convinced that this is the case, but we?re not fully not-convinced, either. We just abandoned it when we tried to squeeze in an Eunhyuk joke in there, and realized we?d be murdered. Screw that! We?re dedicated to corny jokes, but not that dedicated!
Otherwise, this is the first video that we?ve talked about on our KpopCharts that wasn?t in first place since we announced the Personal-Choice-Among-Top-3 rule. You guise vote for the top 3, we pick one and make our video on that. This rule is, amongst other things, to try to prevent the vast amount of boybands out there from ruling our Kpop Music Mondays, like they did in 2012. Sure, it sucks that we didn?t review U-Kiss this time, but hopefully we?ll review them next week! Uggh. Tumblr ban for the next week!
Anyhow, if you?re a fan of this song like we are (and you definitely must be. This song RAWKS!) pick it up on either iTunes or YesAsia. Do it! And, we were rather on point this week for Music Monday, so we don?t have as many bloopers as usual, but if you?re addicted to watching us mess up, here?s Martina making out with our giant Unicorn a bit too much?

Trending Now at SXSW: Wacky developments from world of tech
Here at the South by Southwest Interactive Conference, tons of startups and tech companies are vying to get people's attention. Since we're in Austin, a city known for being weird, it turns out that some of the most interesting and innovative technology being exhibited at the conference also happens to be a little offbeat.
For example, if you ever get tired of 'liking' things on Facebook all the time and want to be a little more negative, there's the 'Hater' App for iOS. Hater's Chief Executive, Jake Banks, says the app was made to, "share the things you hate with the people you love." Users make profiles to upload photos of the things they can't stand- long lines, self-taken photos, or "selfies," and for some, Kim Kardashian. So if you're looking for a way to cut the positivity and just vent a little bit about the things that annoy you, Hater might be for you. It's available for iOS devices now.
If you're looking for a combination of things you never thought you would see, how about Twitter, and cycling? Well, thanks to digital ad company Razorfish, SXSW is overrun with 'tweeting bikes' employing UseMeLeaveMe.com. The bikes tweet both their location using GPS, as well as clever quips like, 'Who needs a ride to their lunch date? Better yet, who needs a lunch date? Find me and I'm all yours." Riders can hop on, take one where they need to go, and leave it for the next person who needs a quick ride.
Finally, we have some technology that might have potential to change the health world. Intelligent M, a startup being featured at SXSW Interactive, addresses one problem that is surprisingly common in hospitals- washing one's hands. According to Intelligent M, 100,000 people a year in the United States alone die because of infections that arise from hospital visits. The company created a wristband that monitors how often and how properly hospital staff are washing their hands, 24 hours a day, 7 days a week. Now that sounds like some cleanliness we can get on board with.
Have you heard of any cool technology you would like to share with us? Tell us on Facebook, or follow us on Twitter, and don't forget to use the hashtag #YahooTrendingSXSW.
