Confirmed: Martian rocks landed in Morocco
CBS News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Scientists are confirming a recent and rare invasion from Mars: meteorite chunks from the red planet that fell in Morocco last July. This is only the fifth time scientists have confirmed chemically Martian meteorites that people witnessed as they fell. The fireball was spotted in the sky six months ago, but the rocks were not discovered on the ground in North Africa until the end of December. More

Setting off a supervolcano
Earth Magazine    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Supervolcanoes are one of nature's most destructive forces, but given that there are no recorded observations of super-eruptions — the last occurred 74,000 years ago in Indonesia — scientists don't fully understand how they work. Now a team studying the world's fastest-inflating volcano, Bolivia's Uturuncu, is shedding some light on how supervolcanoes become so powerful. More

The world's slowest clock
Physorg.com    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The argon-argon clock is used to date rocks and estimate the time of geological events that occurred as far back as 4.5 billion years ago, when the Earth was formed. The new research will increase the accuracy of these estimates by correcting measurements of argon first made in the 1950s by American physicist Alfred Nier. The argon-argon clock works by measuring the ratio of the amount of radioactive potassium in a sample of rock to the amount of its decay product, argon. The older a rock is, the more potassium has decayed and the more argon is found in the rock. More

UK scientists find 'lost' Darwin fossils
Time    Share    Share on FacebookTwitterShare on LinkedinE-mail article
British scientists have found scores of fossils the great evolutionary theorist Charles Darwin and his peers collected but that had been lost for more than 150 years. Dr. Howard Falcon-Lang, a paleontologist at Royal Holloway, University of London, said that he stumbled upon the glass slides containing the fossils in an old wooden cabinet that had been shoved in a "gloomy corner" of the massive, drafty British Geological Survey.

Carbonation brings diamonds to surface
ScienceNews    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Drop a Mentos candy in a bottle of Diet Coke, and carbon dioxide will bubble violently out of the soda. Similar chemical reactions may send certain kinds of magma frothing up from deep within the Earth, carrying diamonds along the way. The discovery, reported in Nature, solves several mysteries about why and how diamond-bearing rocks appear where they do. As gem-laden magma rises, the theory goes, it gobbles a mineral called orthopyroxene, changing the magma's chemical composition and belching carbon dioxide gas that drives its continued ascent. More

Newly discovered molecule has potential to offset climate change and cool the planet
GizMag    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers claim a newly discovered molecule found in the Earth's atmosphere holds the potential to help offset global warming by actually cooling the planet. The molecule is a Criegee biradical or Criegee intermediate, which are chemical intermediaries that are powerful oxidizers of pollutants produced by combustion, such as nitrogen dioxide and sulfur dioxide. They have the ability to naturally clean up the atmosphere by helping break down nitrogen dioxide and sulfur dioxide to form sulfate and nitrate, which ultimately leads to cloud formation that could help cool the planet.

An abundance of exoplanets changes our universe
Scientific American    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Planets in habitable zones, planets orbiting twin suns, miniature solar systems, rogue planets, planets, planets, planets. If there is one single piece of information you should take away from the recent flood of incredible exoplanetary discoveries it is this: Our universe makes planets with extraordinary efficiency — if planets can form somewhere, they will.
