The Space Within: How Architected Voids Promote Tissue Formation

open access: yesAdvanced Materials, EarlyView.
This review explores the role of void spaces in tissue engineering scaffolds and examines four key methods for introducing porosity into hydrogels at different scales. It discusses sacrificial templating, microgels, phase separation, and 3D printing, highlighting principles, advantages, and limitations. It also addresses emerging strategies integrating

The Warm–Hot Disk–Halo Interface below the Perseus Spiral Arm

open access: yesThe Astrophysical Journal
The Milky Way’s disk–halo interface mediates energy and mass exchange between the interstellar thin disk and the halo. In the first detailed study of the Perseus arm’s disk–halo interface, we combine Hubble Space Telescope/Space Telescope Imaging ...

Virus Enhanced Microrobots for Biofilm Eradication

open access: yesAdvanced Materials, EarlyView.
Biofilms resist antimicrobials across medicine, industry, and environments. We present virus‐conjugated microrobots synthesized hydrothermally and magnetically actuated. Their motion and viral specificity enable targeted binding, penetration, and delivery, outperforming bare microrobots.

A New High-latitude H i Cloud Complex Entrained in the Northern Fermi Bubble

open access: yesThe Astrophysical Journal Letters
We report the discovery of 11 high-velocity H i clouds at Galactic latitudes of 25°–30°, likely embedded in the Milky Way’s nuclear wind. The clouds are detected with deep Green Bank Telescope 21 cm observations of a 3 $\mathop{.}\limits^{\unicode{x000b0}

Zinc‐Coordinated Trienzyme Nanogel Cascade Therapy for Accelerated Post‐Pancreatectomy Cutaneous Wound Healing

open access: yesAdvanced Materials, EarlyView.
A zinc‐coordinated nanogel assembly is reported that co‐delivers three enzymes to regulate glucose, oxidative stress, and oxygen levels. This system mimics natural enzyme cascades to reprogram the wound environment after pancreatectomy. In a post‐pancreatectomy mouse model, it accelerates healing by reducing infection, promoting blood vessel growth ...

Lithium‐Charged Gold Nanoparticles: A New Powerful Tool for Lithium Delivery and Modulation of Glycogen Synthase Kinase 3 Activity

open access: yesAdvanced Materials, EarlyView.
This study introduces glutathione‐stabilized gold nanoparticles for targeted lithium delivery (LiG‐AuNPs), enabling the controlled modulation of Glycogen Synthase Kinase‐3 (GSK‐3β). These non‐toxic, 2‐nm particles release lithium intracellularly, effectively inhibiting GSK‐3β in the brain without significant plasma lithium alterations.
