Scientists confirm that parts of earliest genetic material may have come from the stars
Scientists have confirmed for the first time that an important component of early genetic material which has been found in meteorite fragments is extraterrestrial in origin, in a paper published on 15 June 2008. View More (2008-06-16)
Recycling: A new source of indispensible 'rare earth' materials mined mainly in China
That axiom of sustainability - "recycle and reuse" - could help ease concerns about a reliable supply of substances, indispensible for a modern technological society, that are produced almost exclusively in the Peoples' Republic of China. View More (2011-06-30)
Rosetta closes in on Earth - a second time
ESA's comet chaser, Rosetta, is on its way to its second close encounter with Earth on 13 November. The spacecraft's operators are leaving no stones unturned to make sure Earth's gravity gives it the exact boost it needs en route to its destination. View More (2007-11-09)
First habitable-zone super-Earth discovered in orbit around a Sun-like star
NASA's Kepler Mission has discovered the first super-Earth orbiting in the habitable zone of a star similar to the Sun. A team of researchers, including Carnegie's Alan Boss, has discovered what could be a large, rocky planet with a surface temperature of about 72 degrees Fahrenheit, comparable to a comfortable spring day on Earth. This landmark finding will be published in the Astrophysical... View More (2011-12-06)
Ancient Earth crust stored in deep mantle
Scientists have long believed that lava erupted from certain oceanic volcanoes contains materials from the early Earth's crust. View More (2013-04-25)
We Owe It All to Comets
Comets have always fascinated us. A mysterious appearance could symbolize God's displeasure or mean a sure failure in battle, at least for one side. View More (2009-04-29)
EARTH: Antarctic trees surprise scientists
"Warm" and "Antarctica" are not commonly used in the same sentence; however, for scientists, "warm" is a relative term. A team of researchers has discovered that, contrary to previous thinking, the Antarctic continent has experienced periods of warmth since the onset of its most recent glaciation.

Heavy metal glass helps light go the distance
The fiber optic cable networks linking the world are an essential part of modern life. To keep up with ever-increasing demands for more bandwidth, scientists are working to improve the optical amplifiers that boost fiber optic signals across long distances. View More (2010-06-16)
Calculations favor reducing atmopshere for early Earth
Using primitive meteorites called chondrites as their models, earth and planetary scientists at Washington University in St. Louis have performed outgassing calculations and shown that the early Earth's atmosphere was a reducing one, chock full of methane, ammonia, hydrogen and water vapor.

Global change conference sets the scene for next round of Kyoto Protocol talks
Throughout the world, scientists are seeing clear signs that the Earth is rapidly changing. Tropical glaciers are melting fast and some will disappear within 15 years if current warming trends continue. Fifty percent of the land surface has been modified and more than half the world’s accessible freshwater is being used directly or indirectly by humans. These and many other changes are...

Earliest meteorites provide new piece in planetary formation puzzle
Researchers trying to understand how the planets formed have uncovered a new clue by analysing meteorites that are older than the earth. View More (2005-09-20)
Continents loss to oceans boosts staying power
New research suggests that the geological staying power of continents comes partly from their losing battle with the Earth's oceans over magnesium. View More (2008-04-02)
Study sheds new light on how the sun affects the Earth's climate
The Sun's activity has recently affected the Earth's atmosphere and climate in unexpected ways, according to a new study published today in the journal Nature. View More (2010-10-07)
Anthropocene Continues to Spark Scientific Debate
How have humans influenced Earth? Can geoscientists measure when human impacts began overtaking those of Earth's other inhabitants and that of the natural Earth system? View More (2012-11-02)
Evidence from Hawaiian volcanoes shows that Earth recycles its crust
A geologist at Rutgers, The State University of New Jersey, has come up with evidence our planet practices recycling on a grand scale. View More (2006-11-30)
New discovery at Jupiter could help protect Earth-orbit satellites
Radio waves accelerate electrons within Jupiter's magnetic field in the same way as they do on Earth, according to new research published in Nature Physics this week. The discovery overturns a theory that has held sway for more than a generation and has important implications for protecting Earth-orbiting satellites. View More (2008-03-10)
How rusty is the Earth?
An iron object lying around outside quickly turns rusty. Iron metal always has to be combined with some other elements or coated with paint to stop it corroding. The reason for this is that iron metal is unstable in the presence of the oxygen in the Earth's atmosphere. It reacts with the iron to produce ferric iron, a form of iron that exists in iron oxide molecules that are particularly rich in... View More (2004-06-10)
SECCHI team obtains images of the solar wind at Earth
Using the Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) instruments on board NASA's Solar Terrestrial Relations Observatory (STEREO) spacecraft, a consortium of scientists has seen, for the first time, large waves of solar material sweeping past Earth. View More (2007-12-10)
Sustainable development now more urgent than ever, says IGBP scientist
GOTHENBURG - The global environment is in the midst of a profound transformation making sustainable development a matter of urgency, said Dr Will Steffen from the International Geosphere-Biosphere Programme (IGBP, www.igbp.kva.se) at a major international consultation on education for sustainability in Gothenburg today. Dr Steffen, Executive Director of IGBP, told the delegates from 80 countries... View More (2004-05-05)
Fear no supernova
Given the incredible amounts of energy in a supernova explosion - as much as the sun creates during its entire lifetime - another erroneous doomsday theory is that such an explosion could happen in 2012 and harm life on Earth. View More (2011-12-19)
