A Wild Ride On NASA's Massive Flight Simulator

NASA Ames' Vertical Motion Simulator, the largest-such simulator in the world, has been used since 1980 to help train pilots to fly helicopters, fighters, and space shuttles. Now, it is being used for training on the next-generation lunar lander. (Credit: Daniel Terdiman/CNET)

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."

Air France Airbus A380 Completes First Transatlantic Flight from Matt Molnar on Vimeo.



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.

Have The Climate Wars Of Africa Begun?


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.

Herschel Telescope 'Fingerprints' Colossal Star


From The BBC:

The death throes of the biggest star known to science have been observed by Europe's new space telescope, Herschel.

The observatory, launched in May, has subjected VY Canis Majoris, to a detailed spectroscopic analysis.

It has allowed Herschel to identify the different types of molecules and atoms that swirl away from the star which is 30-40 times as massive as our Sun.

VY Canis Majoris is some 4,500 light-years from Earth and could explode as a supernova at any time.

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.

Trend Watch 2010: Mobile Movies

From CNET:

As we move toward 2010, there is little question that mobile devices and smartphones will continue to have a huge impact on the market. Research firm Nielsen predicts that smartphones will dominate market share by the end of 2011, with the iPhone and Android-based phones taking the lead spots by a wide margin over traditional cell phones.

As devices mature, Wi-Fi connections become more ubiquitous, and 3G networks become more reliable, consumers will start looking for new ways to use their smartphones as replacements for other larger devices, such as PCs and TVs. One area that has been called out for growth is mobile video and TV, as well as streaming movies directly to a mobile device.

2011 Ferrari 458 Italia Supercar Test Drive


From Popular Mechanics:

MARANELLO, Italy—Ferarri's new lust-worthy 562-hp supercar hits 60 mph in 3.4 seconds. It's indisputably attractive, but it is also derivative, as though it had been concocted from the best parts of previous great Ferrari designs. Let's see what it can do on real roads.

The Specs:

Ferrari's early cars were dominated by V12 engines. But the Italian sports car maker inherited its first V8 from Lancia in 1955, and its mid-engined V8 sport coupes have been the backbone of the company's model range for the last 35 years. Strictly speaking, the first road-going production-V8 Ferrari was the wedge-shaped, Bertone-designed Dino GT4 of 1973. The most recognizable was of course the Pininfarina-designed 308 launched at the 1975 Paris Motor Salon—a car that starred quite prominently in the hit TV series Magnum PI.

From New Scientist:

After decades of searching, astronomers have confirmed that a gluttonous stellar remnant that glows brightly in X-rays can create high-energy gamma rays as well. The tiny powerhouse could serve as a nearby laboratory to study how particles are accelerated in the universe's biggest black holes.

Cygnus X-3, a pair of objects that sit some 30,000 light years from Earth, has long been a puzzle. The system is thought to contain the dense remnant of a star – either a black hole or a neutron star – that is feeding on a disc of material stolen from a companion star.

From Cosmos:

PARIS: Slowing population growth would help battle global warming, says an unprecedented U.N. report that links demographic pressure and climate change.

"Slower population growth... would help build social resilience to climate change's impacts and would contribute to a reduction of greenhouse-gas emissions in the future," the U.N. Population Fund (UNFPA) says.

Its 104-page document emphasises that population policies be driven by support for women, access to family planning, reproductive health and other voluntary measures.
