Wikipedia Founder Dismisses Claim The Site Is Losing Thousands Of 'Editors'

Photo: Jimmy Wales, the co-founder of the site contested the claim that 49,000 volunteer editors had left in the first three months of 2009

From The Daily Mail:

Wikipedia's co-founder has called into question research which suggests thousands of volunteer editors across the world had left the site thereby undermining its usefulness.

Jimmy Wales contested the claim that 49,000 volunteer editors had left in the first three months of 2009.

'Our internal numbers don’t confirm all the claims made. We do agree that the number of editors has stabilised, as one would expect, since we're already the fifth most popular website on the internet...[however] our own data shows that the number of active editors across all projects is stable – i.e. the new editors are replaced at about the same pace as existing editors are leaving,' he told the Telegraph.

Multiple Sclerosis 'Blood Blockage Theory' Tested

Image: The answer may lie with blood flow

From The BBC:

US scientists are testing a radical new theory that multiple sclerosis (MS) is caused by blockages in the veins that drain the brain.

The University of Buffalo team were intrigued by the work of Italian researcher Dr Paolo Zamboni who claims 90% of MS is caused by narrowed veins.

He says the restricted drainage, visible on scans, injures the brain leading to MS.

He has already widened the blockages in a handful of patients.

The US team want to replicate his earlier work before treating patients.

From Time Magazine:

At first it sounded like science fiction, curing genetic diseases by giving people new genes. Then it seemed like simple fiction: while theoretically possible, gene therapy appeared unlikely to become a true therapeutic option, the field having suffered years of complications and high-profile setbacks. But over the past year, a series of small but intriguing advances has suggested that the technique may hold real future potential.

Scientists Take The First Step In Unlocking Origins Of Universe

The Cern computer system displays images generated of the
first collisions to take place in the Large Hadron Collider. CERN

From The Independent:

After 10 years – and £6bn – the first particles finally smash into each other in the Large Hadron Collider.

After embarrassing breakdowns caused by bread-dropping birds and hugely expensive repairs, the world's biggest science experiment – the Large Hadron Collider – has suddenly burst into life and smashed together proton beams for the first time.

Scientists operating the giant £6 billion machine at Cern, the nuclear research body near Geneva, said yesterday that they had finally succeeded in making low energy proton collisions, which could eventually provide clues about the first Big Bang and the origins of the universe.

Networked Surveillance Minicopters Can't Be Kept Down

From New Scientist:

The helicopter in this video may weigh only 30 grams, but it carries a compass and motion sensors, can change course and warn fellow craft of obstacles it bumps into, and could even carry a small camera. It can also resist what might be called a King Kong attack – if swatted out of the air the tiny craft soon recovers and takes off again.

Did The NSA Helped With Windows 7 Development?

From Computer World:

Privacy expert voices 'backdoor' concerns, security researchers dismiss idea.

Computerworld - The National Security Agency (NSA) worked with Microsoft on the development of Windows 7, an agency official acknowledged yesterday during testimony before Congress.

"Working in partnership with Microsoft and elements of the Department of Defense, NSA leveraged our unique expertise and operational knowledge of system threats and vulnerabilities to enhance Microsoft's operating system security guide without constraining the user to perform their everyday tasks, whether those tasks are being performed in the public or private sector," Richard Schaeffer, the NSA's information assurance director, told the Senate's Subcommittee on Terrorism and Homeland Security yesterday as part of a prepared statement.

From The Guardian:

The wing-like heads of hammerhead sharks with their widely spaced eyes give the creatures excellent binocular vision.

The bizarre appearance of hammerhead sharks has led generations of marine biologists to ponder the same question: why the wide face?

Part of the answer may now be at hand. Eye tests on species caught off the coasts of Florida and Hawaii show that the wider the head the better the shark's binocular vision, and hence its perception of distance.

From CNET News:

MOUNTAIN VIEW, Calif.--There I was, staking my claim to a pilot's slot in one of NASA's next-generation lunar landers, and to be perfectly frank, I think I'd better not quit my day job.

"I think we probably walked away from that," said NASA aerospace engineer Eric Mueller, after one rough touchdown. It was an overly charitable assessment of my performance. I'd hate to know what he was really thinking.

Congress Launches Climategate Investigation

From The New American:

Climategate scientists are under congressional investigation in the wake of information gleaned from e-mails pirated from a global-warming research center in England.

The e-mails revealed evidence that scientists with the United Nations Intergovernmental Panel on Climate Change (IPCC) have been manipulating data to prove their theories of anthropogenic (man-made) global warming (AGW). Senator James Inhofe (R – Okla.) announced on November 24 that he will launch an investigation into the matter, sending letters to the scientists involved and to federal agencies warning them to "retain [related] documents."

From Popular Mechanics:

Air France on Friday became the first European airline to operate the double-decker Airbus A380 in commercial service, completing its inaugural flight from Charles De Gaulle Airport in Paris to John F. Kennedy Airport in New York.

While Air France is actually the third carrier to operate the world’s largest commercial aircraft on U.S. routes—following Emirates and Qantas—this flight marks perhaps the most politically significant milestone the A380 program has achieved so far, connecting the country where Airbus assembles the aircraft to the home of the manufacturer’s archrival, Boeing.

Kenyans Draw Weapons Over Shrinking Resources -- L.A. Times

Experts fear the conflicts involving cattle, water and land may be just the beginning of climate-driven violence in Africa. At least 400 people have died in northern Kenya this year, the U.N. says.

Reporting from Isiolo, Kenya - Have the climate wars of Africa begun?

Tales of conflict emerging from this remote, arid region of Kenya have disturbing echoes of the lethal building blocks that turned Darfur into a killing ground in western Sudan.

Tribes that lived side by side for decades say they've been pushed to warfare by competition for disappearing water and pasture. The government is accused of exacerbating tensions by taking sides and arming combatants who once used spears and arrows.

The aim, all sides say, is no longer just to steal land or cattle, but to drive the enemy away forever.

50 Practical Tips To Save You Half A Lifetime

From Times Online:

When I was 16 I didn’t want agony-aunt advice on sex and love, but real advice on spots and shaving – like this . . .

Dear Sir. Dear Madam. Dear me.

As a lamentation rather than a greeting, “dear me” occurred as I flicked through a clever book (proceeds to the Elton John Aids Foundation) recommended by my colleague Libby Purves. “Dear Me — a letter to my sixteen-year-old self” is an anthology of letters to themselves from a range of famous people. Some are moving, some self-pitying, some funny, many patronising, and a few verbose. All are intriguing.

The Science And Magic Of Breadmaking

Use your loaf: Making bread was surely one of humankind's first chemistry experiments.
Graham Turner/Guardian

From The Guardian:

As winter sets in, warm your senses by baking your own fresh bread. Andy Connelly guides you through the magical process that turns flour and water into heavenly food.

When I think of bread my mind goes back to cold Saturday mornings with ice on the inside of the patio doors and cartoons blazing on the television. My dad would get up early and, after eating his porridge, would begin to make bread.

He would mix all the ingredients in a large ceramic bowl that was crystal-white on the inside and biscuit-brown on the outside. I would watch as the flour became dough and the dough grew and grew in the warm kitchen. I would linger near the oven to smell the earthy fresh bread as it baked, waiting for the treat of eating the crusty end slice of the loaf with a thick slab of butter.
