Devastating earthquakes hit Afghanistan

Lying atop a network of fault lines, where the Indian and Eurasian tectonic plates meet, Afghanistan is prone to earthquakes. However, the Herat area has not seen an event for almost 1000 years. As such, it was the least likely area to experience the series of devastating earthquakes and aftershocks which are reported to have killed thousands this week. Afghani seismologist Zekaria Shnizai discusses the factors which led to the disaster.

After a couple of delays, NASA’s Psyche mission is due to launch this Friday. It will map Psyche, a metal-rich asteroid orbiting the Sun between Mars and Jupiter. Project leader Lindy Elkins-Tanton's excitement for the project is infectious.

And can deep learning help us predict the next pandemic? Computational Biologist Debora Marks’ new tool, Evescape, can predict the most likely mutations a virus will gain under pressure. This could be a game changer.
