3D Rome Created From 150,000 Flickr Photos
From The Telegraph:
Hundreds of thousands of holiday photos posted on Flickr have been used to create 3D models of European cities - including the major sites of Rome.
Scientists from the University of Washington have used advanced photo analysis and modelling techniques to generate fly-though representations of the Colosseum, the Trevi fountain and the Croatian city of Dubrovnik.
The models are created entirely from data taken from images uploaded by members of the public on to the photo-sharing website.

Private Firms Preparing for Moon Flights
Testing, Testing .... Armadillo Aerospace's Super Mod rocket makes the first free-flight landing on a surface designed to mimic a lunar surface. Armadillo Aerospace From Discovery Magazine:
Sept. 21, 2009 -- Lured by millions of dollars in prize money, teams of private firms aren't waiting for NASA to figure out if, when and how to get back to the moon. They're preparing to go themselves.
The first $1 million prize for demonstrating a lunar landing system is due to be awarded at the end of October. The front-runner is Texas-based Armadillo Aerospace, which this month made back-to-back flights of a vehicle named Scorpius.
Two other contenders plan to enter the NASA-backed competition before this year's cutoff on Oct. 31.

Russian Billionaire Installs Anti-Photo Shield on Giant Yacht
From Gadget Lab/Wired:
Russian billionaire Roman Abramovich has a rather curious new addition built in to his latest oversized yacht. The 557-foot boat Eclipse, the price tag of which has almost doubled since original plans were drawn to almost $1.2 billion, set sail this week with a slew of show-off features, from two helipads, two swimming pools and six-foot movie screens in all guest cabins, to a mini-submarine and missile-proof windows to combat piracy.

Recession And Policies Cut Carbon
Photo: Climate protestors in New York are demanding further cuts.From The BBC:
The global recession and a range of government policies are likely to bring the biggest annual fall in the world's carbon dioxide emissions in 40 years.
The International Energy Agency (IEA) estimates that global CO2 emissions will fall by more than 2% during 2009.
Measures such as emissions trading have complemented the drop in emissions as economic activity has declined.
The news comes as leaders gather at the UN for a day of climate talks convened by Secretary-General Ban Ki-moon.
The anticipated fall in emissions is larger than that seen during the recession of the early 1980s.

When You Could Fling A Frisbee From Canada To Zimbabwe
Ancient basalt vein, Greenland Credit: Michael A. HamiltonFrom Live Science:
Imagine flipping a Frisbee in Quebec, Canada, and seeing it land in Zimbabwe. That’s a distance of 8,000 miles now, but 2.6 billion years ago, with good wrist action, it would have been no feat at all (if only there had been Frisbees and, of course, people).
Present-day Quebec and Zimbabwe were adjacent way back then, say geologists who are using new techniques to map Earth’s early continents.

Quantum Computers Are Coming – Just Don't Ask When
Will quantum computers do for the 21st century what digital computers did for the 20th? (Image: Everett Collection/Rex Features)From The New Scientist:
WHATEVER happened to quantum computers? A few years ago, it seemed, it was just a case of a tweak here, a fiddle there, and some kind of number-crunching Godzilla would be unleashed upon us. Just as digital processors changed our lives in ways hard to imagine a few decades ago, the monstrous information processing power of individual atoms and electrons would mean that computing - and the world - would never be the same again.

Earth Approaching Sunspot Records
Charlie Perry, a research hydrologist with the U.S. Geological Survey in Lawrence, sifts through graphs of data in explaining why he believes solar activity may have greater impacts on global temperatures than previously thought. COREY JONES/THE CAPITAL-JOURNALFrom CJ Online:
The average person may not associate coolness with the sun.
The sun releases energy through deep nuclear fusion reactions in its core and has surface temperatures as hot as 10,000 degrees Fahrenheit, according to NASA's Web site.
Not cool at all.
But the sun's recent activity, or lack thereof, may be linked to the pleasant summer temperatures the midwest has enjoyed this year, said Charlie Perry, a research hydrologist with the U.S. Geological Survey in Lawrence.

We Trust People More If They Resemble Us
There are people we trust instinctively and those we do not, says the research. More often than not, this decision is based on physical appearance. Credit: iStockphotoFrom Cosmos:
GUILDFORD, U.K.: A new study has found that subconsciously we are more likely to trust people with similar facial features to our own, but less likely to be physically attracted to them.
There are people we trust instinctively and those we do not, says the research. More often than not, this decision is based on physical appearance.
Using computer graphics, a team led by Lisa DeBruine from the University of Aberdeen in Scotland, manipulated faces so they looked more or less similar to participants in their study. Effectively, the faces either resembled siblings or not, said DeBruine.

Hunting Hidden Dimensions
From U.S. News And World Report:Black holes, giant and tiny, may reveal new realms of space.
In many ways, black holes are science's answer to science fiction. As strange as anything from a novelist's imagination, black holes warp the fabric of spacetime and imprison light and matter in a gravitational death grip. Their bizarre properties make black holes ideal candidates for fictional villainy. But now black holes are up for a different role: heroes helping physicists assess the real-world existence of another science fiction favorite—hidden extra dimensions of space.

How Cooking Helped Us To Evolve
From Times Online:
The success of the human species is all down to our mastery of fire and cooking, a scientist claims. And hot food not sex was the basis for our relationships.
It is the ultimate domestic cliché: a woman, pinafored and dutiful, tending a stove all day in preparation for her husband’s homecoming. As soon as he walks in, the ritual can begin: family members take their seats around the table (he sits at the head, of course) and dinner is served. Our couple are reliving a scene that has played out billions of times in our history because gender roles — husband at work all day, woman as homebody — have been forged not by relatively recent social conventions but by our distant evolutionary past.

WHO: H1N1 Vaccine Production To Fall Short
From Time Magazine:(GENEVA) — Global production of swine flu vaccines will be "substantially less" than the previous maximum forecast of 94 million doses a week, the World Health Organization said Friday.
The number of doses produced in a year will therefore fall short of the 4.9 billion doses the global health body previously hoped could be available for the pandemic, WHO spokesman Gregory Hartl told reporters in Geneva.
Production will be lower because some manufacturers are still turning out vaccines for seasonal flu — an illness that can be serious in sick and elderly people, Hartl said.
