New clues to deep earthquake mystery

A new understanding of our planet's deepest earthquakes could help unravel one of the most mysterious geophysical processes on Earth. Deep earthquakes -- those at least 300 kilometers below the surface -- don't typically cause damage, but they are often widely felt. These earthquakes can provide vital clues to understanding…

The Influence of Nanoparticle Shape on Protein Corona Formation

Nanoparticles (NPs) have become an integral part of many aspects of modern medicine, becoming utility in a wide range of areas such as drug delivery, medical imaging, and diagnostics. In this context, mesoporous silica nanoparticles (MSNs) are particularly interesting for medical applications because of their biocompatibility, biodegradability, large surface‐to‐volume ratio,…
