A Novel Perfused Full‐Thickness Human Skin Microphysiological System for Modeling Injury, Regeneration, Tumor Pathophysiology, and Therapeutics Development

Advanced Healthcare Materials, EarlyView.
What if human skin could remain fully alive and functional outside the body for weeks? A New Alternative Method (NAM) based on a vascularized full‐thickness skin microphysiological system achieves precisely this, preserving native vasculature, resident immunity, and metabolic activity for up to three weeks, while faithfully recapitulating radiation ...

Detecting Satellite Breakup Events via Density-Based Spatial Clustering of Space Debris

Aerospace
When artificial satellites disintegrate in orbit due to collisions, explosions, or anti-satellite tests, they generate a large amount of space debris. These debris move in orbit through formation-like flight patterns, which we refer to as debris clusters.

Detecting Plastic Debris from Space

, 2023
Prove plastic detection in river, dams and canals is possible using non-commercial satellites. Make use of Google Earth Engine (GEE) to access and process large time-series of Sentinel-2 data on the cloud. Estimate surface occupied by plastic debris at sub-pixel level using spectral unmixing.

Encoded Cell‐Material Interactions to Reroute Cytokine Signaling for Regenerative Medicine

Advanced Healthcare Materials, EarlyView.
We present native MATRIX (Material Activated To Regulate Inducible gene eXpression), a co‐engineered material‐cell platform. Surfaces functionalized with antibodies for endogenous soluble ligands (e.g., IL‐1β or IL‐6) capture and immobilize ligands for presentation to a cognate, engineered synthetic Notch receptor, releasing a transcription factor (TF)

Quadratic Shift-and-stack for Ground-based Optical Detection of Faint Cislunar Objects

The Astronomical Journal
Detecting faint objects in cislunar space using ground-based optical telescopes is difficult because of their low brightness, strong lunar background, and complex, nonlinear apparent motion.

Multi-Sensor Space Debris Tracking for Space Situational Awareness With Labeled Random Finite Sets

IEEE Access, 2019
As a result of the dependence worldwide on satellite technology, it is now necessary to use advanced multi-target tracking algorithms for space debris tracking systems to maintain custody of space objects around the earth.

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Stable Protein‐Based G‐Quadruplex‐Derived Supramolecular Bioinks as Tunable ECM‐Mimetic Constructs Assembled by Combining Non‐Covalent and Covalent Strategies

Advanced Materials, EarlyView.
Harnessing the synergistic interplay of supramolecular self‐assembly, under macromolecular crowding conditions, and enzymatic‐mediated covalent crosslinking toward a stable protein‐based G‐quadruplex‐derived supramolecular bioink. This bioinspired strategy enables the biofabrication of complex and tunable ECM‐mimetic constructs, providing a platform ...
