4.4 billion-year-old meteorite found in the Sahara sheds light on infant Mars
A meteorite found in the Sahara last year by Bedouin tribesmen is a rock from Mars, revealing that the Red Planet’s crust formed 4.4 billion years ago, scientists reported on Wednesday. Sold to the elite club of meteorite collectors, the extraordinary rock has been analysed by US and French geologists.

Something unknown has blocked the progress of the biggest tunnel-boring machine in the world
SEATTLE — A secret subterranean heart, tinged with mystery and myth, beats beneath the streets in many of the world’s great cities. Tourists seek out the catacombs of Rome, the sewers of Paris and the subway tunnels of New York. Some people believe a den of interstellar aliens lurks beneath Denver International Airport.

Scientists discover giant trench under Antarctic Ice
The research involved scientists from Newcastle University, the University of Bristol's Glaciology Centre, the British Antarctic Survey and the universities of Edinburgh, Exeter, and York. They charted the Ellsworth Subglacial Highlands – an ancient mountain range buried beneath several kilometres of Antarctic ice - by combining data from satellites and ice-penetrating radars towed behind skidoos and on-board small aircraft.

Mystery Mars rock reveals unexpected chemical composition
The rock that suddenly appeared next to the NASA’s Opportunity rover in the beginning of January turns out to have an irregular chemical composition for Mars: it has too much sulfur, magnesium and manganese, scientists say.

Why China just built this lantern-shaped research base in Antarctica
Antarctica is the world’s last unexploited continent, and the latest site of a global race over resources and status. Over the weekend, China unveiled its fourth research station in Antarctica, where sovereignty is unclear and countries try to stake their claims on the area by building large research bases. The 1,000 square-meter (10,763 sq. feet) Taishan base, also known as “the lantern” because of the shape of its main building, sits near stations run by the US, Italy and South Korea.

Evolution stuck in slime for a billion years
Tasmanian researchers have revealed ancient conditions that almost ended life on Earth, using a new technique they developed to hunt for mineral deposits. The first life developed in the ancient oceans around 3.6 billion years ago, but then nothing much happened. Life remained as little more than a layer of slime for a billion years. Suddenly, 550 million years ago, evolution burst back into action – and here we are today. So what was the hold-up during those 'boring billion' years?

Earth Tones
This image of a large sample of Seven Springs jasper with hematite illustrates some of the colorful earth tones found north of the Phoenix area. Jasper is a variety of silica-rich chert (quartz) with many impurities including iron oxide. Note that the actual size of this rock face is approximately 12 in by 18 in (20 cm by 45 cm)..

Yellowstone Supervolcano Has Been Found to Be Active
The Yellowstone supervolcano has been found to be active even if it probably is not close to erupting any time soon. That is good to know since if the enormous volcano located under beneath the park ever exploded, it could send out ash that covered most of the United States,. Of course, the Yellowstone Caldera as it is officially known, has not erupted in around 70,000 years and only appears to erupt about every 700,000 years.

Magma rising in Washington state's Mount St. Helens volcano: USGS
Magma levels are slowly rebuilding inside Mount St. Helens, a volcano in Washington state that erupted in 1980 and killed 57 people, although there was no sign of an impending eruption, U.S. scientists said. The roughly 8,300-foot volcano erupted in an explosion of hot ash and gas on May 18, 1980, spewing debris over some 230 square miles and causing more than a billion dollars in property damage.

What Caused a 1300-Year Deep Freeze?
The study “pulls the rug out from under the contrived impact hypothesis quite nicely,” says Christian Koeberl, a geochemist at the University of Vienna. Most evidence for the extraterrestrial impact hypothesis, he says, was conjured up “out of thin air.”

Seven earthquakes shake Oklahoma in two days
On Saturday and Sunday in Oklahoma, there were seven earthquakes. You read that right. Not tornadoes. Earthquakes. The most severe temblor registered 4.3 near Langston, the U.S. Geological Survey site showed, delivering a rumble to Logan County, north of Oklahoma City, according to the U.S. Geological Survey. There were no reports of damage or major injury on Saturday, CNN affiliate News9 said.

Mount Fuji Is In A 'Critical State' And Could Be Ready To Blow, Researchers Say
After 307 years, the massive active volcano in Japan may be due for another eruption as a result of a buildup of pressure from the 9.0-magnitude earthquake that hit the country's eastern coast in 2011. While volcano eruptions may often be difficult to predict, a new study published by a team of French and Japanese researchers indicates that Mount Fuji is in a particularly precarious state.
