Precisely designed oxygen carriers enable low-temperature methane reforming

"Methane reforming" is a process that turns methane (CH4) into hydrogen—which can be utilized as an environmentally friendly source of energy. The biggest downside is that methane reforming, in its current state, is not quite ...

The depths of Neptune and Uranus may be 'superionic'

The interiors of ice giant planets like Uranus and Neptune could be home to a previously unknown state of matter, according to new computational simulations by Carnegie's Cong Liu and Ronald Cohen. Their work, published in ...

Cow manure digesters really do cut methane—unless they leak

A new study shows that systems designed to capture methane from cow manure, called dairy digesters, are highly effective. But on the rare occasions they fail, the leaks are large enough to offset their climate benefits.

Thawing permafrost becomes 25 to 100 times more permeable, experiments find

Experiments by University of Leeds researchers, published in Earth's Future, have shown that thawing of permafrost makes it between 25 and 100 times more permeable, allowing more climate change forcing gases to escape.
