Scientists demonstrate high-efficiency quantum dot solar cells

Research shows newly developed solar powered cells may soon outperform conventional photovoltaic technology. Scientists from the National Renewable Energy Laboratory (NREL) have demonstrated the first solar cell with external ...

Triton: A subsurface ocean?

Neptune's largest moon Triton is most likely a captured Kuiper Belt Object. The capture of icy Triton and the subsequent taming of its orbit likely led to the formation of a subsurface ocean through tidal heating. New research ...

New study links extreme weather to climate change

Scientists said Monday they have identified a physical mechanism behind the extreme weather that has plagued many parts of the world in recent years—and that it is tied to climate change.

New model reveals how huddling penguins share heat fairly

Penguins that face the bitter cold and icy winds of Antarctica often huddle together in large groups for warmth during storms. Mathematicians at the University of California, Merced created a model of penguin huddles that ...
