DNA hydrogels are biocompatible drug delivery systems for targeted therapeutic interventions. Conventional DNA hydrogels, formed with many DNA nanostructure units, lead to increased preparation costs and design complexities. To address this, researchers from Japan constructed a Takumi-shaped DNA nanostructure with minimal DNA units and optimized its structure for improved in vivo retention abilities and sustained drug release. This study presents a promising DNA-based drug delivery system, which can potentially improve patient outcomes.

New findings from NASA’s James Webb Space Telescope explain the Phoenix cluster’s mysterious starburst. Data confirm the cluster is actively cooling and able to generate a huge amount of stellar fuel on its own. 

Researchers have been working for decades to understand the details of where the proton gets its intrinsic angular momentum, otherwise referred to as its spin. Recently, there have been indications that the spin contribution of the gluons could either be positive or negative. Now, a new approach that avoids assumptions and re-analyzes observational data with lattice quantum chromodynamics points strongly toward a positive gluon spin contribution, ∆g, to the proton spin.
