The observation of gamma ray bursts and terrestrial gamma-ray flashes with AGILE

, 2011
Since its early phases of operation, the AGILE mission is successfully observing Gamma Ray Bursts (GRBs) in the hard X-ray band with the SuperAGILE imager and in the MeV range with the Mini-Calorimeter.

Neurovascular coupling in bone regeneration: Mechanisms, advanced biomaterials and challenges

BMEMat, EarlyView.
This figure illustrates various material strategies for neurovascularized bone regeneration, including electroactive scaffolds, ion‐loaded materials, drug delivery systems, surface modifications, cells/cell products, growth factors, and peptides. These approaches aim to synergistically promote the regeneration of neural, vascular, and bone tissues ...

EXTRAGALACTIC GAMMA-RAYS: GAMMA RAY BURSTS AND BLAZARS

International Journal of Modern Physics A, 2005
The extragalactic gamma-ray sky is dominated by two classes of sources: Gamma-Ray Bursts (GRBs) and radio loud active galactic nuclei whose jets are pointing at us (blazars). We believe that the radiation we receive from them originates from the transformation of bulk relativistic energy into random energy.

Programmable three‐state nanoreactor for spatiotemporally controlled tumor therapy

BMEMat, EarlyView.
The OMVs are shielded with a biocompatible Da–Ca shell, which prolongs its circulation period and promotes intratumoral accumulation. Importantly, the biocompatible Da–Ca shell can be controllably disintegrated in tumor microenvironment by using laser irradiation, generating in situ hyperthermia and releasing Ca2+.

The Progenitor and Central Engine of Short-duration GRB 201006A Associated with a Coherent Radio Flash

The Astrophysical Journal
Recently, the detection of a coherent radio flash associated with short-duration GRB 201006A, occurring 76.6 minutes after the burst, has attracted great attention. However, the physical origin of the coherent radio flash remains under debate.

Gamma ray bursts observed with WATCH‐EURECA

, 1994
The WATCH wide field x‐ray monitor has the capability of independently locating bright Gamma Ray Bursts to 1° accuracy. We report the preliminary positions of 12 Gamma Ray Bursts observed with the WATCH monitor flown on the ES spacecraft EURECA during ...

Exosome‐mimetic vesicle‐encapsulated multi‐responsive antibacterial hydrogel core‐shell microneedle patch promotes scarless healing of infected wounds

BMEMat, EarlyView.
The core‐shell microneedle patch VP@FNV‐CuO2‐MN was fabricated by encapsulating n‐CuO2 in a moderately crosslinked PVA/CMCS/Borax4 hydrogel shell and VP‐loaded fibroblast membrane nanovesicles (VP@FNV) in a highly crosslinked PVA/CMCS/Borax6 hydrogel core. Upon application to an infected wound, the acidic microenvironment triggers Fenton‐like reactions

Diversity in Fermi/GBM Gamma-Ray Bursts: New Insights from Machine Learning

The Astrophysical Journal
Classification of gamma-ray bursts (GRBs) has been a long-standing puzzle in high-energy astrophysics. Recent observations challenge the traditional short versus long viewpoint, where long GRBs are thought to originate from the collapse of massive stars ...

Nanoagonist‐mediated spatiotemporal reprogramming of macrophage phenotypes to potentiate tumor immunotherapy

BMEMat, EarlyView.
This review systematically summarizes the major molecular mechanisms governing TAM polarization and their coordinated interactions. It further highlights recent advances in nanoagonist‐based strategies that intervene in these pathways to reprogram TAMs, critically discussing their therapeutic potential, current limitations, and translational prospects.

GRB 221009A and the Apparently Most Energetic Gamma-Ray Bursts

The Astrophysical Journal
Gamma-ray bursts (GRBs) are often referred to as the most luminous explosions in the Universe, due to their short and highly luminous prompt emission.
