Arsenic-eating bacteria found, NASA

NASA scientists are putting their ideas of life back under the microscope, after a surprising discovery in California.

They found an organism whose basic building blocks include arsenic, a substance that is poisonous to most things living on Earth. And that’s making them re-think what organisms need to survive – here on earth, and elsewhere.

After days of rampant speculation that NASA was on the cusp of revealing it had detected extraterrestrial life, the reality was slightly more down-to-Earth.

A team of scientists revealed Thursday that they had found a remarkable quality in a bacterium growing quietly in California’s Mono Lake — it is the only known life form able to subsist on the deadly element arsenic. The organism even uses arsenic to build the backbone of its DNA.

To researchers searching for life elsewhere in the universe, the discovery still qualified as a heaven-sent event.

Karin Kloosterman: Are You Hot or Not? - Green Dating Version With 7 Tips

A lot has changed since our parents were in the dating scene. They couldn't break up over an SMS, show how they swap spit on Facebook, or hook-up through the plethora of online dating sites available to us now. Some are paid sites like the popular JDate, Plenty Of Fish, or Yahoo Personals but there are many free dating sites and directories to choose from to meet your match.

But more than how people meet today has been a game changer in the dating scene: with more mindfulness to our planet, navigating through a date -- especially when you find that perfect he or she to be green-minded is -- risky business. If you haven't earned yourself a Green MBA chances are there's a lot to learn. And I am here to offer you some very creative "green" dating tips to impress, seduce and sweep that perfect "green" someone off their feet.

1. Know what they do (and don't) eat
Environmentalists can be tricky to feed, since many stay away from the highly-polluting meat industry. The question is, how much do they steer clear of meat? Your vegetarian sweetheart may not eat fish and your vegan honey may not eat, well, honey. Yeah that's right, honey. Vegans avoid all animal-produced food items (the most obvious of which are dairy and eggs), including the sweet, golden apiarian nectar. So before starting preparations on that romantic home cooked meal, know the deal.

2. Un-pimp your ride
If you're dating somebody who counts carbon emissions like a cheerleader counts calories, consider not showing up for your date in a huge, flashy SUV. Wanna really turn them on? Show up in a super gas efficient car, or better yet - a tandem bike. Don't have either? A walk would be eco-acceptable as well.

3. Wear vintage clothing
While some singles like their dates to be wearing the trendiest, newest duds out there, you are probably more likely to catch an environmentalist's eye by wearing second-hand vintage clothing. Used clothing requires no additional energy (and carbon emissions) to produce, and since it can't be found in a chain store splattered all over the place it is sure to make you stand out as well.

4. Brush up on your environmental lingo
The environmental movement has developed some new terminology since they taught you about ecology and how important it is to recycle in the 5th grade. "Locavore", believe it or not, has nothing to do with locomotive trains and "carbon footprint" doesn't refer to an actual footprint left in a block of carbon. Read TreeHugger, or my own green blog Green Prophet for the latest news.

5. Get a library card and use it
Most environmentalists are all about reducing unnecessary energy consumption wherever possible. This includes reducing energy consumption in the personal entertainment sector which, if you want to have a classic dinner and a movie date, is tricky. Your green date is bound to be more impressed by a home cooked meal (see tip number 1) and a movie rented from the library than a swanky meal at a wasteful restaurant and a movie projected onto a huge screen.

6. Take super short showers
In preparation for your date, haul a timer with you into the shower. You and your date can turn it into a flirtatious competition - who took the shorter shower (and therefore saved much more water) before going out? You get extra points if you use homemade shampoo and conditioner (note to self: add the word "paraben" to your new environmental jargon). Don't forget to wash behind your ears, though.

7. Set the mood with candles
If you're having your green, vegetarian/vegan love interest over for the evening, save a little electricity and set the mood with some candles. Just make sure the candles are made out of soy and not regular paraffin wax (which is made from petroleum and scores you far fewer points). See? Environmentalism can be romantic too.

*Last but not least: there are a number of popular green dating sites out there like Ethical Singles to choose from. But I wouldn't suggest that you limit your online dating search and online instincts by meeting just through sites like these. Today you'll find environmentalists lurking and cropping up everywhere on free dating sites.

I hope some of these tips will both educate and help you navigate your way through a good date, the first step on the road to a green wedding (common law or legal) ... and hopefully green bouncing babies ...

House Votes on Middle Class Tax Cuts: Raw Video

The White House and congressional Republicans have begun working behind the scenes toward a broad deal that would prevent taxes from going up for virtually every U.S. family and authorize billions of dollars in fresh spending to bolster the economy.
Negotiations have accelerated in recent days as Congress has confronted deadlines for extending a series of tax cuts that expire at the end of the month, renewing emergency jobless benefits and keeping the government funded into next year.

The talks mark the dawn of a new era on Capitol Hill, with resurgent Republicans holding far more leverage and commanding a more prominent role in crafting legislation. The private discussions, which parallel a more public set of talks, have left many Democrats grousing that President Obama is being too quick to accommodate his adversaries, who are still a month away from taking control of the House and expanding their presence in the Senate.

Republicans are demanding that Democrats extend Bush-era tax cuts at all income levels at least temporarily, not just those that primarily benefit the middle class. They are also pressing Democrats to approve a measure to keep the government funded through September, a move aimed at avoiding a fight with the White House over spending that could provoke a government shutdown.

AlaskaDispatch.com: Damming Alaska's Mighty Susitna River?

The proposed Susitna River hydro project in Alaska would involve building the biggest dam in the United States in 50 years and change the flow of one of the most loved rivers in the state.

In most places, especially the West, where dams are being torn down and not put up, building a $4.5 billion, massive concrete wall in the middle of nowhere would be unthinkable. But this is Alaska, and the Susitna hydro project is as close as it's ever been in the 30 years that the state has been talking about it.

Last week, the Alaska Energy Authority released a new report touting the Susitna River hydro project over other large hydro proposals as the best way to meet energy needs in the Railbelt, an area stretching from the Kenai Peninsula to Fairbanks. At the same time, Gov. Sean Parnell said he plans to introduce legislation that would allow AEA to pursue funding for and ownership of the project.

"I just absolutely believe this is a go," said state Sen. Lesil McGuire, an Anchorage Republican who has been co-chair of the state Senate Resources Committee. "Having the governor come out and make this a legacy issue for him, at the top of his agenda, has given it a real chance for success."

James Denselow: Haunted by the Soviet Afghan Legacy

The US-led occupation of Afghanistan now outlasts the Soviet presence in the country, with recent tactical changes providing worrying parallels

The revelations of Wikileaks diplomatic cables will absorb headlines and historians for some time; however there is a danger in our attention being too focused on US views of the past rather than the worrying direction of the Afghan conflict in the present.

The narrative of Obama's Afghan strategy is being increasingly muddled by a gap between its rhetoric and its reality. The rhetoric was that a surge of troops combined with the effective use of the new counterinsurgency tactics would win hearts and minds and connect the Afghan state to its violent hinterland. The reality is that General McChrystal always struggled to turn the US military into an army of solider monks. Indeed this week a US Army medic pleaded guilty to being a member of a 12 man 'kill team' that killed Afghan civilians at random and collected their fingers as trophies. An inability to change the character of the occupying force has combined with the massive levels of corruption and an absence of real legitimacy within the government in Kabul, making it impossible to gain effective sovereignty over the country.

The 2014 deadline for leaving the country is likely to slip with Obama warning that "it is hard to anticipate exactly what is going to be necessary to keep the American people safe as of 2014". Despite NATO's senior civilian representative Mark Sedwill claiming that Kabul was safer than London, in November the Pentagon announced that violence in the country was at an all time high, with the numbers of clashes having increased fourfold since 2007.

Greater rates of violence are the consequence of continued failure, and US adjustments to such violence are increasingly showing parallels to Soviet tactics. Interestingly a year ago NATO approached Russia for assistance in Afghanistan, an approach which has now developed into Russian support training the Afghan army and the possible provision of attack helicopters. The US originally avoided the use of tanks in Afghanistan precisely to avoid comparisons to the Soviet occupation, however last month it was announced that main battle tanks were being deployed to Helmand, although according to a US Colonel they won't be used to 'oppress' the Afghans.

As the US passes the milestone of outlasting the Soviet occupation of the country their counterinsurgency strategy is at great peril of ignoring the failures of the Soviet experience. The return of the Russian helicopters and the introduction of US tanks is simply the latest reminder of the slippage in policy as Obama's rhetoric has crashed against the immovable shores of the Afghan reality.
