Origin of Life: Hypothesis Traces First Protocells Back to Emergence of Cell Membrane Bioenergetics
December 20, 2012 — A coherent pathway -- which starts from no more than rocks, water and carbon dioxide and leads to the emergence of the strange bio-energetic properties of living cells -- has been traced for the ... > full story -
When the Ice Melts, the Earth Spews Fire
December 19, 2012 — It has long been known that volcanic activity can cause short-term variations in climate. Now, researchers have found evidence that the reverse process also occurs: Climate affects volcanic ... > full story -
Nanoscale Impulse Radar Measures Depth of Snow and Ice for Alpine Ski Slopes
December 17, 2012 — Snow is the be-all and end-all for alpine ski resorts. Now a tiny sensor has been developed to determine how much cold gold there is on the slopes and how much more should be produced. The sensor is ... > full story -
'Missing' Polar Weather Systems Could Impact Climate Predictions
December 16, 2012 — Intense but small-scale polar storms could make a big difference to climate predictions, according to new research. Difficult-to-forecast polar mesoscale storms occur frequently over the polar seas; ... > full story -
Finding Life in the Volcanic Systems of the Antarctic Polar Front
December 13, 2012 — Volcanic waters in the cold Southern Ocean are the destination for RRS James Cook's current expedition. Scientists are exploring a 2-mile deep water system of hydrothermal vents, calderas and cold ... > full story -
Was Life Inevitable? New Paper Pieces Together Metabolism's Beginnings
December 12, 2012 — A new synthesis by two researchers offers a coherent picture of how metabolism, and thus all life, arose. The study offers new insights into how the complex chemistry of metabolism cobbled itself ... > full story -
Mining Ancient Ores for Clues to Early Life
December 10, 2012 — An analysis of sulfide ore deposits from one of the world's richest base-metal mines confirms oxygen levels were extremely low on Earth 2.7 billion years ago, but also shows that microbes were ... > full story -
Smuggler's Tunnels: Detecting Tunnels Using Seismic Waves Not as Simple as It Sounds
December 10, 2012 — You’d think it would be easy to use seismic waves to find tunnels dug by smugglers of drugs, weapons or people. You’d be wrong. Scientists are now working to improve the detection of ... > full story -
NASA-NOAA Satellite Reveals New Views of Earth at Night
December 5, 2012 — Scientists have unveiled an unprecedented new look at our planet at night. A global composite image, constructed using cloud-free night images from a new NASA and NOAA satellite, shows the glow of ... > full story -
