Glial hyper-drive for triggering epileptic seizures

When epileptic patients suffer seizures, their brain is undergoing repetitive and excessive neuronal firing. But what triggers this has stumped scientists for years. Now, researchers have used fluorescence calcium sensors to track astrocytes’ role in e…

The Italian central Apennines as a source of CO2

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, depending on the type of rock…

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 have demonstrated how these events can be triggered by a small external shock wave. Bring a flotation dev…
