NASA postpones Mars 'flying saucer' test on Earth
Bad weather is preventing NASA from launching a "flying saucer" into Earth's atmosphere to test technology that could be used to land on Mars.
How Earth avoided global warming, last time around
Geochemists have calculated a huge rise in atmospheric CO2 was only avoided by the formation of a vast mountain range in the middle of the ancient supercontinent, Pangea. This work is being presented to the ...
Study shows Deepwater Horizon crude oil impairs swimming performance of juvenile mahi-mahi
