Long-lived lakes reveal a history of water on Mars

The northern hemisphere of Mars is divided into two broadly distinctive areas: the smooth northern lowlands and the pockmarked southern highlands. The region of Arabia Terra sits along the transition between these two regions ...

Melting permafrost increases greenhouse gas from Arctic lakes

Groundwaters that circulate through the subsoil as a result of melting permafrost can transport carbon dioxide and methane to Arctic lakes and in turn be emitted to the atmosphere. This process of transporting greenhouse ...

Attosecond measurement on electrons in water clusters

Virtually all vital chemical processes take place in aqueous solutions. In such processes, a decisive role is played by electrons that are exchanged between different atoms and molecules and thus, for instance, create or ...

New method helps exfoliate hexagonal boron nitride nanosheets

Chinese researchers recently reported an innovative mechanical process for controllably exfoliating hexagonal boron nitride nanosheets (h-BNNSs).This method, known as the "water-icing triggered exfoliation process," was proposed ...
