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.
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.
After years of planning, scientists are set now to send missions to explore the ocean world of Europa.
Scientists have mapped out the best materials for either carbon dioxide capture or balancing carbon capture with methane selectivity.
Open hardware systems could make robots more affordable and easier to build
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.
In the future, solar cells can become twice as efficient by employing a few smart little nano-tricks, suggest investigators in a new report.
Through genetic mutations microorganisms normally have the ability to develop new properties over a short time scale.
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.
Researchers develop a model they hope can be used to understand how dolphins and whales react physiologically to threats from predators and people.
If most of the world’s coral reefs die, some of the richest and most colorful life in the ocean could be lost, along with huge sums from reef tourism.
The world is getting warmer every year, thanks to climate change — but where exactly most of that heat is going may be a surprise.
