Ultra‐Thin Tow‐Based Discontinuous Composites—Material Overview and Aspirations

Advanced Functional Materials, EarlyView.
Tow‐based discontinuous composites made from ultra‐thin tapes offer outstanding in‐plane mechanical properties. This material, inspired by Nacre, has high volume fraction of tapes exceeding 90 % and allows for quasi‐isotropic material plates less than 100 micrometer in thickness.

A 16 Myr Super-Neptune in Upper Centaurus Lupus and a Preliminary Survey of Transiting Planets in Sco-Cen with TESS

The Astronomical Journal
Measuring the properties of planets younger than about 50 Myr helps to test different planetary formation and evolution models. NASA’s Transiting Exoplanet Survey Satellite (TESS) has observed nearly the entire sky, including a wide range of star-forming

Architectural Tuning of Bouligand Electrospun Laminates Enables Coupled Mechanical Robustness and Electromechanical Sensing

Advanced Functional Materials, EarlyView.
Bioinspired Bouligand architectures are translated into biodegradable polymer laminates with integrated sensing, revealing how structural design governs multifunctional performance. A 20° interlayer rotation optimizes strength, flexibility, and electromechanical response, while embedded nanotube networks enable real‐time damage detection and wearable ...

Evolution of Nuclear Star Cluster in Dwarf Galaxy through Mergers and In Situ Star Formation

The Astrophysical Journal
Nuclear star clusters (NSCs) are dense stellar systems located at the centers of galaxies. Employing Enzo- Abyss , which integrates hydrodynamics with a direct N -body solver, we introduce a simulation capable of resolving the evolution of NSCs within a ...

A first GLIMPSE into star-cluster populations across cosmic time

Astronomy & Astrophysics
We present the first sample of 218 high-redshift (z > 0.5) star clusters, detected with JWST/NIRCam in 78 magnified galaxies from different galaxy cluster fields. The majority of the systems (~60%) are observed in the very deep NIRCam observations of the

Hydrogel‐Based Method for High‐Resolution Measurements of Contact Mechanics in Rapid Biological Adhesives: A Case Study in Cuttlefish Tentacle Strikes

Advanced Functional Materials, EarlyView.
Cuttlefish and squid can catch their prey within milliseconds using specialized tentacles and suckers. The physics of how the suckers can attach so quickly has remained a mystery given the technical challenges of studying them in vivo. In this publication, we develop a hydrogel that retains imprints of the suckers in order to estimate the forces they ...

Tracing the Earliest Stages of Star and Cluster Formation in 19 Nearby Galaxies with PHANGS-JWST and HST: Compact 3.3 μm Polycyclic Aromatic Hydrocarbon Emitters and Their Relation to the Optical Census of Star Clusters

The Astrophysical Journal
The earliest stages of star and cluster formation are hidden within dense cocoons of gas and dust, limiting their detection at optical wavelengths. With the unprecedented infrared capabilities of JWST, we can now observe dust-enshrouded star formation ...

Bioprinted Stiffness‑Tunable Pancreatic Microniches to Decode Early Tumor Initiation Mechanisms

Advanced Healthcare Materials, EarlyView.
Stiffness‐tunable GelMA microniches generated by microvalve bioprinting preserve wild‐type acinar identity while revealing a nonlinear, Kras‐dependent response to matrix mechanics. Intermediate stiffness promotes acinar‐to‐ductal metaplasia and proliferation, defining a permissive mechanical window.
