Investigating the porosity of sedimentary rock with neutrons

Whether sedimentary rocks store fossil hydrocarbons or act as impermeable layers to prevent the rise of oil, natural gas or stored carbon dioxide—all depends on their porosity. The size, shape, organization, and connectivity ...

The Italian central Apennines are a source of CO₂, study finds

Tectonically active mountains play an important role in the natural CO2 regulation of the atmosphere. Competing processes take place here: At Earth's surface, erosion drives weathering processes that absorb or release CO2, ...

Scientists trigger mini-earthquakes in the lab

Earthquakes and landslides are famously difficult to predict and prepare for. By studying a miniature version of the ground in the lab, scientists at the UvA Institute of Physics have demonstrated how these events can be ...

A better way to predict Arctic riverbank erosion

Arctic riverbanks are typically resilient, thanks to the power of permafrost. This permanently frozen soil locks in sediment, leading to low erosion rates. But as Arctic river water warms due to climate change, some researchers ...
