This study reports on the chemical modification of hyaluronic acid to create hydrogels with hydrolytic degradability ranging from 2–28 days. Granular hydrogels that undergo timed degradation to increase porosity enhance cell invasion and provisional ECM remodeling in a muscle injury model, leading to reduced fibrosis and improved regeneration ...

Formation scenarios of dense starless cores from their ice composition
Context. Dense, dark, starless cores of molecular clouds form in large-scale processes. The evolution of physical conditions in forming dense cores is often regulated by external phenomena and cannot be easily reproduced with models considering only the ...

A Noninvasive Approach to Study Localized Forces in 3D Epithelia
Epithelial morphogenesis depends on dynamic mechanical coupling between adhesion complexes and the cytoskeleton, yet its regulation in polarized 3D tissues remains elusive. We developed a noninvasive strategy using cell‐like elastic microbeads to quantify local forces in intact epithelia.

Defined PEG hydrogels enable human iPSC‐derived intestinal organoid culture without Matrigel. PEG‐ and Matrigel‐cultured organoids both support duodenal‐like epithelial identity, but direct comparison reveals subtle epithelial differentiation‐marker shifts and stronger mesenchymal ECM‐remodeling/integrin programs in PEG.

H4F talk with Dania Achermann: Ice cores, small states and global climate change
For our final talk of the series H4F chat with Dania Achermann the topic “Histories of Climate Science”. We talk about Dania’s research on ice-core paleoclimatology and the cultural-political factors that shape how we know and understand climate sciences.

Bilayered PEDOT:PSS–Collagen Scaffolds as Functional Architectures for Tissue Engineering
A bilayered scaffold integrates collagen and PEDOT:PSS as distinct yet interconnected 3D matrices, preserving their fibrillar and conductive characteristics. Spatial compartmentalization enables independent tailoring of each domain while maintaining mechanical stability and compatibility with electrochemical monitoring, providing a multifunctional ...

Bromine Enrichment Signal in Svalbard Shallow Cores Reflects Changes of Seasonal Sea Ice Variability
Bromine enrichment Brenr has been widely used as a proxy for past sea ice reconstructions. In this study, three firn cores drilled on Holtedahlfonna (Svalbard) were analyzed for trace elements.

Control of Bacterial Attachment on Macroporous PDMS/Paraffin SLIPS With Varying Lubricant Viscosity
Slippery liquid‐infused porous surfaces (SLIPS) prepared from macroporous PDMS, infused with medical‐grade paraffins, were systematically investigated regarding the correlation of viscosity, surface corrugation, bulk porosity, and bacterial resistance. Substrate porosity was found to dominate lubricant stabilization and the antifouling activity.
