Discovery shakes beliefs of earth to the core

For a century, scientists have assumed that the Earth has the same chemical make-up as the sun. But this belief has been challenged by scientists at The Australian National University. Professors Ian Campbell and Hugh O’Neill from the Research School of Earth Sciences at ANU said their research shakes up our understanding of the Earth’s […] … learn more→

Revisiting population growth: The impact of ecological limits

The hard part about predicting the future, someone once said, is that it hasn’t happened yet. So it’s a bit curious that so few experts question the received demographic wisdom that the Earth will be home to roughly 9 billion people in 2050 and a stable 10 billion at the century’s end.

The researchers, writing in the September issue of the journal Astrobiology, argue that pumice has a unique set of properties which would have made it […] … learn more→

Berkeley scientists discover an \’instant cosmic classic\’ supernova

A supernova discovered Thursday is closer to Earth—approximately 21 million light-years away—than any other of its kind in a generation. Astronomers believe they caught the supernova within hours of its explosion, a rare feat made possible with a specialized survey telescope and state-of-the-art computational tools. The finding of such a supernova so early and so […] … learn more→
