Understanding the atomic density fluctuations in silica glass      (via sciencedaily.com)     Original source 

The intermediate range order of covalent glasses has been extensively studied in terms of the first sharp diffraction peak (FSDP), but the direct observation of the atomic density fluctuations that give rise to FSDP is still lacking. Addressing this gap, researchers employed a new energy-filtered angstrom-beam electron diffraction technique to provide the direct experimental observation for the origin of FSDP in silica glass, providing important insights into the atomic structure of glasses.

Ancient medicine blends with modern-day research in new tissue regeneration method      (via sciencedaily.com)     Original source 

For centuries, civilizations have used naturally occurring, inorganic materials for their perceived healing properties. Egyptians thought green copper ore helped eye inflammation, the Chinese used cinnabar for heartburn, and Native Americans used clay to reduce soreness and inflammation. Flash forward to today, and researchers are still discovering ways that inorganic materials can be used for healing. A new article explains that cellular pathways for bone and cartilage formation can be activated in stem cells using inorganic ions. Another recent article explores the usage of mineral-based nanomaterials, specifically 2D nanosilicates, to aid musculoskeletal regeneration.

Scientists develop most sensitive way to observe single molecules      (via sciencedaily.com)     Original source 

A technical achievement marks a significant advance in the burgeoning field of observing individual molecules without the aid of fluorescent labels. While these labels are useful in many applications, they alter molecules in ways that can obscure how they naturally interact with one another. The new label-free method makes the molecules so easy to detect, it is almost as if they had labels.
