As picture-taking mobile telephones and digital movie cameras grow ubiquitous, Internet users worldwide are being recruited as citizen news reporters.
In December Yahoo launched YouWitnessNews, a website that posts offerings from users after the submissions pass muster with professional editors.
Founded almost two years ago, news website NowPublic.com taps into legions of people that post pictures, videos, or commentary online.
NowPublic boasts more than 60,000 contributing "reporters" in more than 140 countries and promises to quickly locate potential witnesses or news gatherers close to breaking events from natural disasters to terrorist attacks.

Online encyclopaedia Wikipedia might have to close because it only has enough funding for another four months.
Florence Devouard, chairwoman of the Wikimedia Foundation, told the Lift07 conference that the outfit might join the Everywhere Girl and disappear from the Interweb.
Wikipedia normally raises a $1 million a year, this year it has raised $1.1 million. But it claims that it needs $5 million a year to sustain operations.

A new study published in the journal Science bills Enceladus as "a cosmic graffiti artist, caught in the act."
Last spring NASA's Cassini spacecraft showed what appeared to be geysers streaming out from Enceladus's surface.
One theory suggests that the plumes are created by liquid water below the surface that freezes instantly in the moon's frigid surface climate.
"Enceladus coats itself, snows on itself, and distributes pure water ice particles on its surface," said lead study author Anne Verbiscer, an astronomer at the University of Virginia.

Geologists at the University of Illinois at Urbana-Champaign have located a huge chunk of Earth's lithosphere that went missing 15 million years ago.
By finding the massive block of errant rock beneath Tibet, the researchers are helping solve a long-standing mystery, and clarifying how continents behave when they collide.
The Tibetan Plateau and adjacent Himalayan Mountains were created by the movements of vast tectonic plates that make up Earth's outermost layer of rocks, the lithosphere. About 55 million years ago, the Indian plate crashed into the Eurasian plate, forcing the land to slowly buckle and rise. Containing nearly one-tenth the area of the continental U.S., and averaging 16,000 feet in elevation, the Tibetan Plateau is the world's largest and highest plateau.

DNA tests carried out on two British men have shed light on a mystery surrounding the ancestry of Thomas Jefferson, America's third president. In the 1990s, DNA was taken from male relatives of Jefferson to see if he fathered a son with one of his slaves. They found the president had a rare genetic signature found mainly in the Middle East and Africa, calling into question his claim of Welsh ancestry. But this DNA type has now been found in two Britons with the Jefferson surname.
The final design for a "doomsday" vault that will house seeds from all known varieties of food crops has been unveiled by the Norwegian government.

Comment: Hmmm, wonder how many NeoCon vaults there are out there... (and who keeps that sidewalk clear of snow and ice in the North Pole?)
A fleeting pulse of light has been captured and then made to reappear in a different location by US physicists.
The quantum sleight of hand exploits the properties of super-cooled matter known as a Bose-Einstein condensate.
The emerging pulse was slightly weaker than the high-speed beam that entered the experimental setup, but was identical in all other respects.
The work, published in the journal Nature, could one day lead to advances in computing and optical communication.

The study, reported this week in The Journal of Neuroscience, provides the first direct evidence that humans, like rats, moths and butterflies, secrete a scent that affects the physiology of the opposite sex.
"This is the first time anyone has demonstrated that a change in women's hormonal levels is induced by sniffing an identified compound of male sweat," as opposed to applying a chemical to the upper lip, said study leader Claire Wyart, a post-doctoral fellow at UC Berkeley.

Lunar colonists could be in for a nasty shock - literally. A team of US scientists has found that the Moon's surface can become charged with up to several thousand volts of static electricity1.
This charging could release sparks that disable electronic equipment - including monitors, space buggies or even the front door of a Moon base. And it could cause dust clouds that clogs up instruments. What's worse, it can be caused by bad weather in space: just when astronauts need their equipment to give them warning and allow them to shelter from the radiation.

US military engineers are looking to bats for inspiration.
Video footage of bats in flight has revealed extreme aerodynamic flexibility of the creature's wings. Bats' wings are made of highly jointed skeletons and elastic membranes, which allow them to generate and manipulate lift in unusual ways.
For their study, researchers Kenneth Breuer and Sharon Swartz at Brown University in Providence, US, used high -speed video cameras to record the 3D wing and body movements of flying lesser short-nosed fruit bats, Cynopterus brachyotis.
