Chile wildfire under control: president
Hundreds of firefighters in Chile have successfully brought under control a massive blaze that consumed 30,000 acres (12,500 hectares) of a national park in Patagonia, the government said.
Using Loch Ness to track the tilt of the world
That the rise and fall of the tide is primarily driven by the gravitational pull of the moon and the Sun is common knowledge, but not all tides are controlled by such a standard mechanism.
Evaluating the energy balance of Saturn's moon Titan
To understand the weather and climate on Earth as well as on other planets and their moons, scientists need to know the global energy balance, the balance between energy coming in from solar radiation and thermal energy radiated back out of the planet.
Should we terraform Mars?
As we continue to explore farther out into our solar system and beyond, the question of habitation or colonization inevitably comes up. Manned bases on the Moon or Mars for example, have long been a dream of many. There is a natural desire to explore as far as we can go, and also to extend humanity’s presence on a permanent or at least semi-permanent basis. In order to do this, however, it is necessary to adapt to different extreme environments. On the Moon for example, a colony must be self-sustaining and protect its inhabitants from the airless, harsh environment outside.
Twin Grail spacecraft reunite in lunar orbit
(PhysOrg.com) -- The second of NASA's two Gravity Recovery And Interior Laboratory (GRAIL) spacecraft has successfully completed its planned main engine burn and is now in lunar orbit. Working together, GRAIL-A and GRAIL-B will study the moon as never before.
Space mountain produces terrestrial meteorites
When NASA's Dawn spacecraft entered orbit around giant asteroid Vesta in July, scientists fully expected the probe to reveal some surprising sights. But no one expected a 13-mile high mountain, two and a half times higher than Mount Everest, to be one of them.
How to see the best meteor showers of 2012: Tools, tips and 'save the dates'
(PhysOrg.com) -- Whether you're watching from a downtown area or the dark countryside, here are some tips to help you enjoy these celestial shows of shooting stars. Those streaks of light are really caused by tiny specks of comet-stuff hitting Earth's atmosphere at very high speed and disintegrating in flashes of light.
Two New Zealand scientists to travel to Antarctica to measure magnetic South Pole
(PhysOrg.com) -- While the rest of the world gets on with meeting the New Year head on, two research scientists from New Zealand are traveling to the Antarctic to take measurements of the magnet South Pole. Such periodic measurements are necessary geo-scientists say, because the magnetic poles keep moving around. The south magnetic pole, for example is slowly moving north toward Australia at almost ten miles per year; this matters because very accurate ground measurements are necessary to keep satellites properly calibrated, ensuring such things as GPS coordinates are accurate.

British government to fund 3D laser cameras for highway crash site investigations
(PhysOrg.com) -- One of the banes of modern existence is surely the time spent in traffic backups. Oftentimes these backups occur as the result of accidents and the resulting investigative work that goes on before cleanup can commence. Such work must be done in order verify what occurred during an accident for both legal and financial reasons, thus, there is little chance of simply doing away with some of them. There does appear to be hope of developing new ways to do that detective work though, as new technology is developed to help speed things along. One of these new technologies involves the use of laser equipped 3D cameras and computer technology, instead of old fashioned photography and legwork.
