Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels
A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...

Ternary Transistors With Reconfigurable Polarities
Polarity‐reconfigurable ternary transistors are demonstrated using black phosphorus homojunction with asymmetric contacts and split‐gate structures. Suppression of majority carrier injection, while Fowler–Nordheim tunneling of low‐density minority carriers persists, enables a well‐defined intermediate state with improved on/off ratios.

High Thermoelectric Performance in Low‐Cost Cu8SiSxSe6‐x Argyrodite
This study discovers the great potential of Cu8SiSxSe6‐x argyrodites as new, low‐cost, Te‐free thermoelectric materials. The proposed defect scheme suppresses the phase transition, enhances the weighted mobility and optimizes the grain boundary contacts.

A Predicted Great Dimming of T Tauri: Has it Begun?
The optical star in the T Tauri triple system is the prototype of young Sun-like stars in our galaxy. This complex and dynamic system has evidence for misaligned disks and outflows, and molecular material in a circumbinary ring that obscures the southern

The scaffold‐free Anchored Cell Sheet Engineering platform is used to create three‐dimensional (3D) in vitro models of skeletal muscle tissue that replicate key features of Duchenne and Myotonic dystrophies. These personalized tissue models, validated by histological, immunostaining, and proteomics analyses, accurately mimic disease phenotypes and ...

Radial Velocity and Astrometric Evidence for a Close Companion to Betelgeuse
We examine a century of radial velocity, visual magnitude, and astrometric observations of the nearest red supergiant, Betelgeuse, in order to reexamine the century-old assertion that Betelgeuse might be a spectroscopic binary.
