Minor planet 1566 Icarus: Asteroid or comet? [PDF]

By employing a cometary nongravitational force model, based on the outgassing of a water ice nucleus, the orbital fits to the optical and radar astrometric data are improved for both Apollo and Icarus.

An Innovative “Tooth‐On‐Chip” Microfluidic Device Emulating the Structure and Physiology of the Dental Pulp Tissue

Advanced Healthcare Materials, EarlyView.
This work presents a “tooth‐on‐chip” device that mimics dental pulp tissue. By co‐culturing key cell types, it recreates vascular networks, stem cell niches, the odontoblast/dentine interface, and trigeminal innervation. This innovative platform provides a unique model of dental pulp structure and physiology, with significant potential for accelerating

ROS‐Triggered Microgels for Programmable Drug Release in Volumetric Muscle Loss Repair

Advanced Healthcare Materials, EarlyView.
Reduced graphene oxide‐incorporated hyaluronic acid microgels are developed as ROS‐responsive, injectable platforms for curcumin delivery in volumetric muscle loss. The microgels exhibit strong antioxidative activity, high drug‐loading capacity, and ROS‐triggered release.
