Gamma ray emission from embedded young massive star clusters unveiled by Fermi-LAT [PDF]
EPJ Web of ConferencesMassive star clusters (SCs) have been proposed as additional contributors to Galactic Cosmic rays (CRs), to overcome the limitations of supernova remnants (SNR) to reach the highest energy end of the Galactic CR spectrum.

Stars in the Galactic Centre [PDF]
, 2006 In the centre of our Galaxy lies Sgr~A*, a $3.5 \times 10^6$ solar mass black hole, immersed in a star cluster with dozens of massive stars. The very low luminosity of Sgr~A*, and the presence of young stars in the close proximity of a super-massive ...

Advanced Robotics Research, EarlyView.This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

Liquid Metal Nanotransformers for Drug‐Resistant Pan‐Cancer Therapy in Patient‐Derived Organoids
Advanced Science, EarlyView.Pan‐cancer therapies are severely limited in drug‐resistance patients due to genetic mutations and other factors, resulting in poor therapeutic outcomes and constrained clinical benefit. Liquid metal nanotransformers, a new class of shape‐transformable nanomaterials capable of dramatic morphological changes, offer a promising physical strategy to ...

Galactic Superaccreting X-Ray Binaries as Super-PeVatron Accelerators
The Astrophysical Journal LettersThe extension of the cosmic-ray (CR) spectrum well beyond 1 PeV necessitates the existence of a population of accelerators in the Milky Way, which we refer to as super-PeVatrons. Identifying the nature of these sources remains a challenge to the paradigm

Study of Free‐Space Optical Quantum Network: Review and Prospectives
Advanced Science, EarlyView.Free from the constraints of fiber connections, free‐space quantum network enables longer and more flexible quantum network connections. This review summarizes and comparatively analyzes free‐space quantum network experiments based on ground stations, satellites, and mobile platforms.

The Spatially Resolved Hot Gas Properties of NGC 1266’s Active Galactic Nucleus-driven Outflow
The Astrophysical JournalGalactic winds play a critical role in galaxy evolution, yet their structure and driving mechanisms remain poorly understood, especially in low-luminosity active galactic nucleus (LLAGN) systems.

Advanced Science, EarlyView.Producing MSCs on rigid culture substrates induces a scar‐making phenotype, jeapordizing therapeutic success. ‘Tissue‐soft’ surfaces prevent MSC fibrogenesis and preserve regenerative traits. An epigenetic network, driven by HOXA11 and SALL1, maintains ‘soft memory’ by keeping chromatin open in relaxed MSCs, promoting anti‐fibrotic programs.
