Earth’s sixth mass extinction is underway, scientists warn

How would you react if you read in the news that horses are on the endangered species list? Will you be untouched by news that all dogs will be extinct by 2025? How about cats? Take a moment to think about this. Can you imagine a world with no horses, no dogs and no...

Nano-spike Catalysts Convert Carbon Dioxide Directly Into Ethanol

In a new twist to waste-to-fuel technology, scientists at the Department of Energy’s Oak Ridge National Laboratory have developed an electrochemical process that uses tiny spikes of carbon and copper to turn carbon dioxide, a greenhouse gas, into ethanol. Their finding, which involves nanofabrication and catalysis science, was serendipitous.

Earth Just Permanently Passed Climate Threshold

Carbon dioxide concentration in the atmosphere stayed above 400 parts per million (ppm) during September—a time when CO2 levels typically hit the yearly low—raising fears that the planet has reached a point of no return.
