Measurements of trace gases in planetary atmospheres help us explore chemical conditions different to those on Earth. Our nearest neighbour, Venus, has cloud decks that are temperate but hyperacidic. Here we report the apparent presence of phosphine

Simple guidelines to minimise exposure to earthquake-triggered landslides

Autor: Milledge, David, Rosser, Nick, Oven, Katie, Dixit, Amod Mani, Dhungel, Ranjan, Basyal, Gopi Krishna, Adhikari, Sujan Raj, Densmore, Alexander, Earthquake Without Frontiers, NERC, ESRC

Reducing landslide risk in many mountainous regions \ud is most effectively achieved by reducing exposure to \ud landslides, because landslides cannot be predicted or \ud stopped and engineering solutions are generally \ud impractical or impossible.

We conducted a multi-isotope study of five fifth-century AD cemeteries in modern-day Hungary to determine relationships between nomadic-pastoralist incomers—the historically documented Huns and other nomadic groups—and the sedentary agricultural

Reduced graphene oxides with varying degrees of reduction have been produced by hydrazine reduction of graphene oxide. The linear and nonlinear optical properties of both graphene oxide as well as the reduced graphene oxides have been measured by sin
