That's why deals like the one announced Tuesday between Pasadena's eSolar and the Indian conglomerate Acme Group are essential to any truly green global future. ESolar will sell Acme 1,000 megawatts worth of solar thermal technology, so that the latter can build a network of solar power plants in India's northern state of Haryana. "India is an enormous electricity market with enormous demand for growth," said Rob Rogan, vice president of corporate communications for eSolar. "We see this as our chance to be part of a long-term renewable energy solution in India." To date, most wind and solar power has been deployed in the rich, industrialized nations. A 2008 report found that the world's developed countries had installed 207 gigawatts of renewable-power generation, excluding large hydro. That's only a few percent of the rich countries' power generation, but it's a lot more than the 88 gigawatts of clean power that had been built in the developing world. Now, even with the Obama-led United States looking increasingly green-friendly, that trend could reverse. Falling renewable-energy costs and the desire to use domestic energy sources have helped green tech make inroads in fast-growing countries. Renewable-energy investments jumped 91 percent in 2007 in China. and India expects add 6 gigawatts of wind power between 2007 and 2012. Here we present five of the largest green tech projects that have broken ground, or plan to, in 2009. Each one of them is slated to be among the largest green-tech projects in the world. Though each is as big as a large coal plant, your average fossil fuel plant will generate more kilowatt-hours because they can burn round the clock every day the year, not just when the sun is shining or the wind blowing.

"If you have just a few basic things," said University of Colorado at Boulder microbiologist Steven Schmidt, "you can get a complex ecosystem going, even in one of the harshest places on the planet." Schmidt's team studied soil from the upper flanks of the Socompa volcano, high in the Andes mountains. Straddling Chile and Argentina, the volcano is surrounded by the Atacama desert, one of the few spots on Earth to contain regions devoid of any life form. At 20,000 feet above sea level, the Socompa's upper flanks are especially harsh: there's little oxygen, and ultraviolet radiation passes easily through the thin atmosphere. But where steam from the volcano bursts through the ground, there's methane and water. Add that to atmospheric carbon dioxide, and conditions resemble what once existed — and may still exist — on Mars. Scientists recently found that Mars still belches methane into its carbon-dioxide rich atmosphere. And though NASA's Mars Rover found water only in ice, rather than the liquid necessary for life as we know it, many geologists suspect water is present beneath the planet's surface, warmed by the Mars' still-hot core. "The Socompa microbial ecosystem is an extremely exciting Earth analog for investing how life on Mars may survive in hydrothermal oases, where water, heat and nutrients are being provided from deep within," said California Institute of Technology biochemist Adrian Ponce, who was not involved in the study. Schmidt's team sampled soil around volcanic vents, and from regional soils thought to be lifeless. In the vent soil, they identified moss, algae and about 500 species of bacteria. Apart from the discovery of a new species of mite, said Schmidt, these findings are most significant for their level of genomic detail, since the organisms were already known to exist. Far more surprising was the presence of roughly 100
species of bacteria in earth taken miles from volcano's vents. No life
at all was thought to exist in that parched soil. This, she said, might occur "fairly rarely" — an understatement for a region in which years can pass between rainstorms. Lisa Pratt, a NASA astrobiologist who was not involved in the study, mirrored Ponce's excitement, saying the Socompa vents "may be the best example yet of an Earth analogue for habitable surface and near-surface environments on Mars." "If water, a carbon source and energy for metabolism are present, then life seems to manage daunting extremes," said Pratt. That is, if it can get started. Some scientists question whether the chemistry on Mars has ever been conducive for life to begin, even if we know organisms can evolve to survive those same conditions. But life didn't necessarily need to bootstrap itself on Mars: it could have arrived there on rocks knocked into space by an asteroid's collision with some other, more temperate planet.

Source: Wired: Wired Science | 4 Mar 2009 | 12:13 am What is science anyway?Britain's Science Council has spent the past year working out a new definition of the word 'science'. But how does it measure up to the challenge of intelligent design and creationism? It might have been the 16th century philosopher Francis Bacon who coined the term "science", but even if it wasn't, the word must have come into common usage around his time, in the western world at least. Here's what they've come up with:
Not bad for a year's work ... But why bother with a new definition? In a statement from the Council, chief exec Diana Garnham says:
So there you go. I ran the definition past a couple of experts to see what they made of it. David Edgerton, professor of the history of science and technology at Imperial College, made two points:
and
The philosopher AC Grayling thinks the Council has done a good job:
The new definition has left me with two mildly nagging doubts, though. I wonder what it means for those who suggest that intelligent design or creationism are based on science?

Even so, it is expected to lift off aboard a Delta 2 rocket from Cape Canaveral within the next few days. Kepler will not enter Earth-orbit though. Instead it will trail the Earth in orbit around the Sun from where it will have an unbroken view of star-fields in the constellations Cygnus and Lyra, looking for Earth-sized planets about other stars. With a 95 megapixel sensor, its camera is the most powerful ever launched into space, while its primary mirror of 1.4 metres aperture is the largest ever to go beyond Earth-orbit. Yet it will still not image the planets directly. Instead, it is to monitor the precise brightness of some 100,000 stars in our Galaxy, looking for any minute dimming of a star's light as its planet passes in front of it. Any periodicity in the dimming will tell us the planet's "year", while the way the light dims and recovers could betray its size. Knowing the star's energy, and the orbital period of its planet, would tell us whether that planet is in the star's habitable zone where liquid water might persist and life as we know it might be possible. Such transit techniques have been used successfully before, for example by the less-sensitive French/ESA Corot satellite which has so far discovered at least five so-called exoplanets, all larger than the Earth. guardian.co.uk © Guardian News & Media Limited 2009 | Use of this content is subject to our Terms & Conditions | More Feeds

The safe containing the one-gallon vessel was unearthed in 2004 during a clean-up operation of a waste trench at the Hanford nuclear site in Washington state. The clean-up team noticed the jug was partially filled with a mysterious white slurry and sent it for testing. Scientists at Pacific Northwest National Laboratory in Richland have now revealed that the jug contained several hundred milligrams of bomb-grade plutonium, which they have dated to 1944 when the US nuclear programme was still in its infancy. Analysis of the jug's contents shows that the material did not originate at Hanford but can be traced back to the world's first industrial-scale nuclear reprocessing site in Oak Ridge, Tennessee. Jon Schwantes, who led the team of investigators, describes their work as "nuclear archaeology" in the latest issue of the journal Analytical Chemistry. The US nuclear bomb programme was set up in 1939 in response to fears that Nazi Germany was developing a similar weapon. Research and production for the project was based at three sites – Hanford, Oak Ridge and Los Alamos in New Mexico – under the watchful eye of Robert Oppenheimer. During the Second World War, the Hanford facility produced bomb-grade plutonium for Trinity, the first nuclear weapon to be tested, and later for the atomic bomb dropped on Nagasaki in Japan. Schwantes said the forensic techniques used to identify the nuclear relic will come in useful for tracing material confiscated from smugglers caught with black market nuclear materials. "It is likely that with the current nuclear renaissance and greater access to these materials by the public, smuggling events involving fissionable materials may rise in the near future," Schwantes said. guardian.co.uk © Guardian News & Media Limited 2009 | Use of this content is subject to our Terms & Conditions | More Feeds

But let's put that to one side for a moment. Yesterday saw the unveiling of a new portrait of Peter Higgs, the eminent physicist who worked on a concept called spontaneous symmetry breaking in the 1960s. The painting – on display at the School of Informatics, Edinburgh University – is by Ken Currie, one of Scotland's leading artists. I quite like it, but hope Professor Higgs didn't have to stand up for much of the, erm, sitting. In May he will celebrate his 80th birthday. When Higgs first published his theory, it was arcane even for the world of theoretical particle physics. But over the past 40 years, it has endured as the prevailing explanation for how elementary particles acquire mass. It's a big deal. Without it, quarks and electrons would zip about at the speed of light and never combine to form atoms ... or planets ... or us. At least that's how the theory goes. Higgs and others, notably the Anglo-American group of Gerry Guralnik, Richard Hagen and Tom Kibble, plus two Belgian theorists, Robert Brout and Francois Englert, put forward the idea almost simultaneously. Together, they suggest there's an invisible field pervading the entire universe that drags on particles and makes them heavy. Just as electromagnetic fields come with a particular particle, the photon, so the Higgs field comes with its own, the Higgs boson. Finding the boson is now the focus of a frenzied hunt. Right now, the only machine with a chance of finding it is the Tevatron, the world's most powerful particle collider, at Fermilab on the outskirts of Chicago. It was a former director of the lab, the Nobel prizewinner Leon Lederman, who dubbed it the God particle. Come September, it will become the prime target of Europe's most expensive broken toy, the Large Hadron Collider at Cern near Geneva. For the latest on the Higgs race, there's a nice summary on the Cosmic Variance blog. I know scientists hate the name God particle, and it's hard to disagree with any of their reasons for objecting. But I can't help thinking they should lighten up a little. The name has stuck for a reason. At the very least, Lederman boosted the chances of particle physics being written about by the lay media. That has to be good news for the public, who pay for these giant machines to be built, and for the wages of many of those working on them. Moving on. The other night I was kicking around on Vimeo, a site where I've found some truly brilliant movies, when I stumbled upon the Colliding Particles project. It's run by particle physicists Gavin Salam, Jonathan Butterworth and Adam Davison, who looks remarkably like that bloke out of Four Weddings and a Funeral and The Mummy. It's testament to the team's passion for science, their film-making skills and real knack for storytelling that I watched all three episodes back to back. At least I hope that's the explanation. You can watch the movies below, but I'd recommend you also check out their website, which has a wealth of extra material, and you can sign up for future instalments. It's a great project.
