At The Paris Auto Show, Supercars And Stylish Concepts
From Popular Science:
In 1898 the world's first auto show was held in Paris at the Tuilleries Gardens. Only a few vehicles were on display, and people were so skeptical of this new mode of transportation -- Le Car -- that exhibitors had to drive their automobiles from Versailles to Paris to prove their validity.

It's The End Of The World: 8 Potential Armageddons
From FOX News:
Oil plumes threaten to choke the oceans and methane gas explosions shoot sky high -- and those are hardly the biggest threats facing the Earth. From cosmic rays to asteroid impacts to the threat of general destruction, our planet may be less safe than you think.
Here are the top eight risks to life as we know it, detailed by scientists and science fiction writers -- and whether it's even possible to save ourselves.

From The National Geographic:
NASA craft reveals unexpected unpredictability of our protective bubble.
It's cold, dusty, and bereft of planets, but the outskirts of our solar system are anything but dull, according to increasing evidence from NASA's Interstellar Boundary Explorer (IBEX) craft.
As charged particles flow out from the sun, they eventually bump up against interstellar medium—the relatively empty areas between stars. These interactions "inflate" a protective bubble that shields Earth and the entire solar system from potentially harmful cosmic rays (solar system pictures).

NASA's Future Looks Bleak Amid Policy Shift
From The L.A. Times:
The demise of the Constellation moon rocket means 7,000 job losses in a year. Funding for a heavy-lift rocket for asteroid missions will be comparably less than that for the moon rocket.
Reporting from Washington — A new law passed by Congress this week finally gives NASA some badly needed direction, but the future of the space agency remains bleak — at least in the near term.

Reports From The Hive, Where The Swarm Concurs
The author, on Appledore Island, watching a swarm launch into flight from the vertical board that he uses as a swarm mount. The two feeder bottles on the mount provide sugar syrup to keep the swarm well fed. From the book “Honeybee Democracy” by Thomas D. Seeley
From The New York Times:
What can we learn from the bees? Honeybees practice a kind of consensus democracy similar to what happens at a New England town meeting, says Thomas D. Seeley, author of “Honeybee Democracy.” A group comes to a decision through a consideration of options and a process of elimination.

Ray Kurzweil’s Blio E-Book Launch Met With Confusion, Controversy
From Gadget Lab:
This week, K-NFB, an e-reading company founded by Ray Kurzweil and the National Federation for the Blind, launched its much-anticipated Blio reading app and e-book store. Blio was immediately and widely panned by publishers, developers and readers.
“Many of the failures are fundamentally at odds with the one thing that Kurzweil was touting above all else: accessibility,” wrote Laura Dawson, a digital reading industry consultant, formerly of BarnesAndNoble.com. K-NFB initially promised to make e-books more accessible to blind readers; yet Windows, currently its only enhanced books platform, has known text-to-speech conversion issues.

Scribd Facebook Instant Personalization Is A Privacy Nightmare
From Epicenter:
Online document sharing site Scribd hooked up with Facebook to create “instant personalization” so Scribd users can get reading recommendations based on their Facebook likes and what their friends are sharing. Sounds interesting, right?
But the document sharing and embedding service has created a privacy nightmare that involves drafting users who are already logged into Facebook without offering a clear opt out process either on the site or through e-mail.

Industrial computer systems are typically far less secure than they should be, experts say.
For the last few months, a sophisticated computer worm has wriggled its way between some of the most critical control systems in the world.
The timing of the worm's release, combined with several clues buried in its code, has led some experts to speculate that the worm, dubbed Stuxnet, was originally designed to sabotage an Iranian nuclear facility, possibly the enrichment plant in Natanz, roughly 180 miles south of Tehran. This week, officials in Iran confirmed that Stuxnet had been found on systems inside the plant, although they denied that it had caused any harm.

The Supernova's Secrets Cracked At Last?
From Time Magazine:
Most stars end their lives in a whimper — our own sun will almost certainly be one of them — but the most massive stars go out with an impressive bang. When that happens, creating what's known as a Type II supernova, the associated blast of energy is so brilliant that it can briefly outshine an entire galaxy, give birth to ultra-dense neutron stars or black holes, and forge atoms so heavy that even the Big Bang wasn't powerful enough to create them. If supernovas didn't exist, neither would gold, silver, platinum or uranium. The last time a supernova went off close enough to earth to be visible without a telescope, back in 1987, it made the cover of TIME.

Budget Deal Propels NASA On New Path
From Wall Street Journal:
House's Passage of $58 Billion Compromise Bill Funds Commercial Space Travel, More Robotic Deep-Space Missions.
In unusual bipartisan fashion, the House on Wednesday approved a three-year $58-billion compromise bill intended to revive NASA's manned-exploration programs while funding plans for pioneering private rockets able to blast astronauts into orbit.
Capping nearly a year of intense industry turmoil, agency uncertainty and congressional debate, the vote reflected last-minute decisions by House leaders from both parties to embrace a previously-passed Senate blueprint for NASA, though it doesn't completely satisfy any of the rival interest groups or regional factions maneuvering to shape the agency's future.

From The Daily Mail:
The ancient language of Babylonian can be heard for the first time in almost 2,000 years after Cambridge University scholars posted readings and poems online.
Babylonian, one of the chief languages of Ancient Mesopotamia, dates back as far as the second millennium BC but died out around 2,000 years ago.
However, Cambridge historians have resurrected the ancient tongue by discovering how the language was pronounced and spoken.

Rivers Threatened Around The World
From New Scientist:
The water supplying 80 per cent of the world's population is exposed to "high levels of threat". That's the conclusion of a study that surveys the status of rivers throughout the world, and looks at their effects on both humans and the ecosystem at large.
Writing in this week's Nature (vol 467, p 555), Charles Vorosmarty of the City College of New York and colleagues pull together a swathe of data on factors affecting water security, from dams that reduce river flow to the pollution and destruction of wetlands.

Are UFOs Disarming Nuclear Weapons, And If So Why?
Did UFOs Disarm Nuclear Weapons? And If So, Why? -- Live Science
At an unusual press conference recently held in Washington, D.C., a UFO author and a half-dozen or so former U.S. military airmen asserted that "The U.S. Air Force is lying about the national security implications of unidentified aerial objects at nuclear bases and we can prove it." They claim that since 1948, extraterrestrials in spaceships have not only been visiting Earth but hovering over British and American nuclear missile sites and temporarily deactivating the weapons.
