The economic case for wind, solar energy in Africa

While hydropower and fossil fuel power plants are favored approaches in some quarters, a new assessment has found that wind and solar can be economically and environmentally competitive options and can contribute significantly to the rising demand.

Hydrogen production: This is how green algae assemble their enzymes

Researchers have analyzed how green algae manufacture complex components of a hydrogen-producing enzyme. The enzyme, known as the hydrogenase, may be relevant for the biotechnological production of hydrogen.

Europa: Our best shot at finding alien life?

After years of planning, scientists are set now to send missions to explore the ocean world of Europa.

Study refines filters for greener natural gas

Open hardware systems could make robots more affordable and easier to build

Collapsing cliff reveals comet’s interior

Rosetta scientists have made the first compelling link between an outburst of dust and gas and the collapse of a prominent cliff, which also exposed the pristine, icy interior of the comet.

World’s most efficient, environment-friendly solar cells

In the future, solar cells can become twice as efficient by employing a few smart little nano-tricks, suggest investigators in a new report.

Microorganisms in the subsurface seabed on evolutionary standby

Through genetic mutations microorganisms normally have the ability to develop new properties over a short time scale.

Enormous swarms of midges teach about interconnected landscapes

Ecologists are trying to understand why the midge population at an Icelandic lake can fluctuate by 100,000-fold across a decade, and what impact these massive swarms have on the surrounding landscape.
