In its large caldera, Newberry volcano (Oregon, U.S.) has two small volcanic lakes, one fed by volcanic geothermal fluids (Paulina Lake) and one by gases (East Lake). These popular fishing grounds are small windows into a ...

Methanethiol, a potential new feedstock in C1 chemistry

Catalytic conversion of molecules with one carbon atom such as methane, carbon dioxide (CO2), methanol (CH3OH) and others into higher-value chemicals is of major importance for a viable and sustainable chemical industry. ...

Hydrogen sulfide helps maintain the drive to breathe

Effective regulation of breathing pattern is essential for many different mammalian processes such as energy production, metabolic regulation and even speech. Researchers have recently discovered that the body's production ...
