The World's Fastest Computers

5: Tianhe-1. 563 teraflops
A new entrant into the Top500 list, China's fastest computer proved capable of more than 500 trillion operations per second. Put another way, a simple calculator's power is typically about 10 flops. Tianhe, which means "river in the sky", is housed at the National Super Computer Center, Tianjin, and is more than four times faster than the previous top computer in the country. The computer combines 6144 Intel processors with 5120 graphics processing units made by AMD, normally found in computer graphics cards. (Image: Xinhua News Agency/eyevine)

How A Prehistoric 'Super River' Turned Britain Into An Island Nation

From The Daily Mail:

A prehistoric 'super-river' is the reason why Britain became an island and was cut off from Europe.

An Anglo-French study has revealed that long before the English Channel there was a giant river which ran south from an area of the North Sea.

Previous research found that 500,000 years ago a range of low hills connected Britain to Europe between the Weald in South-East England and Artois in northern France.

Peat Fires Drive Temperatures Up: Burning Rainforests Release Huge Amounts of Greenhouse Gases

From Science Daily:

ScienceDaily (Nov. 29, 2009) — Peatlands, especially those in tropical regions, sequester gigantic amounts of organic carbon. Human activities are now having a considerable impact on these wetlands. For example, drainage projects, in combination with the effects of periodic droughts, can lead to large-scale fires, which release enormous amounts of carbon dioxide (CO2) into the atmosphere, and thus contribute to global warming. Using laser-based measurements, Professor Florian Siegert and his research group at Ludwig-Maximilians-Universität (LMU) in Munich have now estimated the volume of peat burned in such fires with unprecedented accuracy.

What's The Environmental Impact Of Going Into Space?

Dirty Rockets -- Slate

We hear so much about the environmental impacts of transportation. What about space travel? How do rockets affect the atmosphere?

There's a simple reason why we hear a lot more about cars, ships, and planes than we do about rocket ships: There are lot more of them. Each flight into space does have a small impact on the planet it leaves behind, but—for the moment, at least—these launchings are very rare. Only a couple of rockets blast off every week around the world. As a result, space travel doesn't register on most environmentalists' radars.

Yeah. The A-37 was small. So was Napoleon.

Looking for Mach-busting splendor in million-dollar wonders from the heavies of the U.S. military-industrial complex? This ain't it. The A-37 Dragonfly was a waist-high, subsonic light attack aircraft that could lift its own weight in fuel and armaments, built by a manufacturer known for civilian pleasure craft. You could get a half-dozen for the price of a single F-4. The A-37 brought jet-propelled combat in Vietnam down from rarefied heights to the low-and-slow—where the acrid haze of rice-burning season permeated the unpressurized cockpit and you plucked bullets from Viet Cong small arms out of the armor plate under your seat after a mission.

The Great Climate Change Science Scandal

From Times Online:

Leaked emails have revealed the unwillingness of climate change scientists to engage in a proper debate with the sceptics who doubt global warming.

The storm began with just four cryptic words. “A miracle has happened,” announced a contributor to Climate Audit, a website devoted to criticising the science of climate change.

“RC” said nothing more — but included a web link that took anyone who clicked on it to another site, Real Climate.

There, on the morning of November 17, they found a treasure trove: a thousand or so emails sent or received by Professor Phil Jones, director of the climatic research unit at the University of East Anglia in Norwich.

Jones is a key player in the science of climate change. His department’s databases on global temperature changes and its measurements have been crucial in building the case for global warming.

FUTURE HUMANS: Four Ways We May, Or May Not, Evolve

Looking backward, evolutionary theory—popularized by Charles Darwin's On the Origin of Species, published in 1859—has traced humanity's roots to fossil apes.

Solar Power Costs 50% Lower Than Last Year

From Scientific American:

New research by leading alternative energy research firm New Energy Finance finds that solar power will cost less by about 50% at the end of 2009 compared to the end of 2008.

The costs are pre-subsidy, so they could be much lower if you take better government subsidies into account.

But it isn’t only solar that’s down in cost. It’s other renewable energy sources, too.
The research company found that equipment costs (in solar, wind, and other sectors) decreased throughout the year but these were offset by increasing financing costs. However, equipment prices are expected to continue falling whereas the financing market is expected to get better.

Pacific Northwest Earthquakes Could Strike Closer To Home

From Wired Science:

Major earthquakes occurring along the Cascadia subduction zone off the coast of Washington state could strike closer to the state’s urban areas than some models have suggested, a new study notes.

GPS data gathered at dozens of sites throughout western Washington hint that slippage along the interface between the North American and Juan de Fuca tectonic plates could occur as deep as 25 kilometers below the Earth’s surface, says Timothy I. Melbourne, a geodesist at Central Washington University in Ellensburg. That depth, in turn, would place the epicenters of quakes triggered along that portion of the subduction zone — some of which could exceed magnitude 9 —more than 60 kilometers inland, he and CWU colleague James Chapman report online and in the November 28 Geophysical Research Letters.

If planet Earth becomes too crowded, where else in the solar system could humankind live? Space expert Steven Cutts considers our options.

For decades, the most popular destination for migrants the world over has been the United States. It was in America that the downtrodden and the footloose of this world saw their destiny. But America's ability to accommodate such people has always been finite. Billions of poverty-stricken people today crave the comfort and the affluence of a better world and almost none of them can have it. The increase in global population now exceeds the entire population of the US every five years; if migration is the solution to the problems of mankind then we're going to have to find a different planet.
