Could The Mono Lake Arsenic Prove There Is A Shadow Biosphere?
From Times Online:
Do alien life forms exist in a Californian lake? Could there be a shadow biosphere? One scientist is trying to find out.
Mono Lake has a bizarre, extraterrestrial beauty. Just east of Yosemite National Park in California, the ancient lake covers about 65 square miles. Above its surface rise the twisted shapes of tufa, formed when freshwater springs bubble up through the alkaline waters.

A Computer That Processes Faster Than The Speed of Light
Pushing the Limits of Physics Exceeding the speed of light opens one up to all kinds of theoretical problems, but two Austrian researchers claim there's no reason we can't build a computer that processes information at superluminal speeds.
From Popular Science:
How fast is too fast? According to the laws of physics, the speed of light is a good boundary, as going beyond it opens you up to all sorts of paradoxes and space-time phenomena that are usually the stuff of sci-fi. But a couple of researchers in Austria have come up with a way to compute information faster than the speed of light.

How Safe Is Your Cell Phone?
From Time Magazine:
It takes a little extra work to get in touch with Andrea Boland. The Maine state representative answers e-mails and lists her business and home phone numbers on the Web. But unlike many politicians surgically attached to their BlackBerrys, she keeps her cell switched off unless she's expecting a call. And if she has her way, everyone in Maine — and perhaps, eventually, the rest of the U.S. — will similarly think twice before jabbering away on their mobiles.
NASA: Space Shuttles Could Fly Longer With Extra Funds
From Space.com:
WASHINGTON – The chief of NASA's space shuttle program said Tuesday that the agency could technically continue to fly its three aging orbiters beyond their planned 2010 retirement if ordered to do so by President Barack Obama and lawmakers. All it would take would be the extra funding needed to pay for it.
Space shuttle program manager John Shannon said NASA spends about $200 million a month on its space shuttle program. That's about $2.4 billion a year that would be required to keep the shuttle flying beyond their 2010 retirement date, he said.

Did 'Midwife Molecule' Assemble First Life On Earth?
From New Scientist:
The primordial soup that gave birth to life on EarthMovie Camera may have had an extra, previously unrecognised ingredient: a "molecular midwife" that played a crucial role in allowing the first large biomolecules to assemble from their building blocks.
The earliest life forms are thought by many to have been based not on DNA but on the closely related molecule RNA, because long strands of RNA can act as rudimentary enzymes. This would have allowed a primitive metabolism to develop before life forms made proteins for this purpose.

New HIV Hiding Spot Revealed
From Science:
Powerful anti-HIV drugs have come tantalizingly close to eradicating the virus from people, driving the blood level of HIV so low that standard tests cannot detect it. But no one has been cured: the virus comes roaring back in everyone who stops taking the drugs. A new study has identified one of HIV's main hideaways, raising intriguing possibilities about how to remove it.

13 Crazy Earthquake Facts
From Live Science:
1. Earth has been more seismologically active in the past 15 years or so, says Stephen S. Gao, a geophysicist at Missouri University of Science & Technology. Not all seismologist agree, however.
2. San Francisco is moving toward Los Angeles at the rate of about 2 inches per year — the same pace as the growth of your fingernails — as the two sides of the San Andreas fault slip past one another. The cities will meet in several million years. However, this north-south movement also means that despite fears, California won't fall into the sea.

More States Propose Internet Sales Taxes
From CNET:
Jeremy Bray received an e-mail message this morning with an unwelcome surprise: Amazon.com told him it had canceled its affiliate program, which provides small payments for referring customers, for everyone in the state of Colorado.
The reason? A state law, which Democratic Gov. Bill Ritter signed last week, slaps onerous new restrictions on large out-of-state sellers like Amazon, which said it has no choice but to end its marketing program in response.

From Discovery News:
Thousands of bodies are already cryonically frozen, waiting for faster computers and medical advances that will undo their cause of death.
What is death? Over the centuries, the line dividing life and death has moved from the cessation first of breathing, then of the heartbeat, and finally of brain activity. But cryogenic methods first contemplated in science fiction may push the line even further. The idea is to freeze legally dead people in liquid nitrogen in the hope of regenerating them at some future date.

What It Takes to Keep a City Afloat -- Wall Street Journal
In One Day, the World's Largest Cruise Ship Prepares to Set Sail, with 700 Tons of Supplies, 80,000 Beers, and One Bagpiper
How do you keep more than 6,300 people fed, housed and having the time of their life while floating in the middle of the ocean?
The Oasis of the Seas—the world's largest cruise ship—aims to accomplish that feat nearly every week. Almost five times as large as the Titanic, it has a population during its seven-day Caribbean sailings that is larger than many American small towns—more than 8,600 when it is fully booked and including staff. The Royal Caribbean Cruises Ltd. ship, which first set sail last December, is almost as long as five Airbus A380 airplanes, or about four football fields. It has 24 restaurants and its own leafy "Central Park." During the weeklong sailings, about 700 tons of new supplies are needed, all loaded aboard each Saturday. Guests consume about 20 gallons of maraschino cherries and 80,000 bottles of beer.

'We Don't Know What 96% Of The Universe Is Made Of
From The Guardian:
Pop star-turned-physicist Brian Cox speaks about his new TV series on the solar system.
It's big space, isn't it?
It's 93 million miles to the Sun: that's a long way. It takes light eight minutes to do that. There are 100bn galaxies in the observable universe. If you take a 5p coin and hold it 75 feet away, the space in the sky it would obscure would hold 10,000 galaxies. It's mindblowing. I don't think anyone has a grasp of that other than to say: it's big.

The Shocking Truth About Tasers
The new long-range Taser rifle, which can immobilise a suspect for 20 seconds from 100ft away, with an X26 pistol mounted beneath it.
From The Daily Mail:
A commuter in a diabetic coma, an 89-year-old man and children as young as 12 - just some of the targets of British police armed with skin-piercing 50,000-volt Taser guns. As the Home Office investigates bringing an even more powerful rifle version to Britain, Jason Benetto reports on the slow creep of arms onto our streets.
The smartly dressed sales executive travelling on the number 96 bus across Leeds didn't notice his body descending into a state of severe hypoglycaemia.
He didn't have time to ask his fellow passengers for help, or press the bell. Instead he slumped back in his seat in a diabetic coma, his head lolling from side to side.
