Mars terraforming not possible using present-day technology

Science fiction writers have long featured terraforming, the process of creating an Earth-like or habitable environment on another planet, in their stories. Scientists themselves have proposed terraforming to enable the long-term ...

Did Phosphorus Trigger Complex Evolution -- and Blue Skies?

(PhysOrg.com) -- The evolution of complex life forms may have gotten a jump start billions of years ago, when geologic events operating over millions of years caused large quantities of phosphorus to wash into the oceans. ...

Wetlands likely source of methane from ancient warming event

An expansion of wetlands and not a large-scale melting of frozen methane deposits is the likely cause of a spike in atmospheric methane gas that took place some 11,600 years ago, according to an international research team ...

Humans adding less nitrogen to oceans than models predict

A new study finds that human activities are likely contributing far less nitrogen to the open ocean than many atmospheric models suggest. That's generally good news, but it also nullifies a potential side benefit to additional ...

Diamond defect boosts quantum technology

New research shows that a remarkable defect in synthetic diamond produced by chemical vapor deposition allows researchers to measure, witness, and potentially manipulate electrons in a manner that could lead to new "quantum ...

Research supports a new approach to counting CO2 emissions

(Phys.org) —Researchers have called for a system of carbon emission assessments that reflect better the true contribution of each emitting nation to the increase in atmospheric CO2 and promote preservation of forests, particularly ...

NASA investigates use of 'trailblazing' material for new sensors

Tiny sensors—made of a potentially trailblazing material just one atom thick and heralded as the "next best thing" since the invention of silicon—are now being developed to detect trace elements in Earth's upper atmosphere ...
