A dusty atmosphere caused extreme global cooling

In recent Earth history, climate has varied following ~100,000 year, glacial-interglacial cycles with higher and lower temperatures and greenhouse gas concentrations. During the coldest glacial conditions, global mean temperatures ...

Worst over, but dangers persist at Japan plant

A month after a deadly quake-tsunami hit a Japanese nuclear plant, the risk of a huge radiation leak has fallen but the danger is far from over, experts say -- a risk brought sharply into focus by a powerful tremor Monday.

High plutonium breeding of light water cooled reactors

Professor Oka and his research team at Waseda University have succeeded in developing the world's first conceptual nuclear reactor design of high plutonium breeding by light water cooling.

Climate engineering could slow Antarctic ice loss, study says

Scattering sunlight-reflecting particles in the atmosphere could slow rapid melting in West Antarctica and reduce the risk of catastrophic sea-level rise, according to a study led by Indiana University researchers.
