Scientists Resurrect Ancient Proteins to Learn about Primordial Life on Earth
Moffet Field CA (NASA) Oct 03, 2014
Geological evidence tells us that ancient Earth probably looked and felt very different from the planet we all recognize today. Billions of years ago, our world was a comparatively harsh place. Earth likely had a hotter climate, acidic oceans and an atmosphere loaded with carbon dioxide. The fact that manmade climate change, through carbon dioxide pollution, is re-introducing such hotter, acidified conditions demonstrates their intertwinement. More recently, the life sciences have begun buttressin ... read more

NASA's Swift satellite sees small star ejecting 'super flares' Astronomers don't normally use canine clichés, but if they did, they might employ one - it's not the size of the dog in the fight, it's the size of the fight in the dog - to describe a small but energetic red dwarf in a binary system known as DG Canum Venaticorum, or DG CVn. That's because red dwarfs like DG CVn serve a serious electromagnetic punch in a small package. ... more		Cyanide fog marks winter's onset on Saturn moon Titan A cyanide cloud formed over Titan's south pole as the strange moon of Saturn entered its seven-year winter in 2009, astronomers reported on Wednesday. ... more		India signs $7 bn deal for 97 domestically made fighter jets France doubles down on threat to build future fighter jet alone US approves $1.2 bn missile sale to Germany		Space debris expert warns of increasing CubeSat collision risk The increasing number of small 'CubeSat' satellites being launched combined with a relaxed attitude to debris mitigation could lead to hazards for all space users unless preventative measures are ta ... more
