Observation of contemporaneous optical radiation from a gamma-ray burst

, 1999
The origin of gamma-ray bursts (GRBs) has been enigmatic since their discovery. The situation improved dramatically in 1997, when the rapid availability of precise coordinates for the bursts allowed the detection of faint optical and radio afterglows ...

Utilizing Synergistic Effect in Pd‐Doped Mesoporous γ‐Al2O3/SnO2 for Multiple Freon Refrigerant Gases Detection

Advanced Sensor Research, EarlyView.
Due to the synergistic effect of improved catalytic decomposition mechanism and Schottky‐barrier effect, the Pd‐γ‐Al2O3/SnO2 sensor exhibits outstanding response, good stability, selectivity, repeatability, and universality in sensing different Freon gases, which demonstrates its potential for use in Freon refrigeration leakage detection.

First results of the BATSE/COMPTEL/NMSU rapid burst response campaign [PDF]

, 1994
The Imaging Compton Telescope (COMPTEL) on board the Compton Gamma Ray Observatory regularly observes gamma‐ray bursts which occur inside the instrument’s ∼1 sr field‐of‐view.

The supernova/gamma-ray burst/jet connection

, 2013
The observed association between supernovae and gamma-ray bursts represents a cornerstone in our understanding of the nature of gamma-ray bursts. The collapsar model provides a theoretical framework for this connection.

Human iPSC‐Derived Mononuclear Phagocytes Improve Cognition and Neural Health across Multiple Mouse Models of Aging and Alzheimer's Disease

Advanced Science, EarlyView.
Short‐term intravenous treatments with iPSC‐derived mononuclear phagocytes (iMPs) improve cognitive decline and neural health in two mouse models of aging and in the 5xFAD mouse model of Alzheimer's disease. iMPs reduce levels of serum amyloid proteins that increase in aging and improve the health of hippocampal microglia and mossy cells.

Gamma-ray burst afterglow blast waves

, 2018
The various stages of baryonic gamma-ray burst afterglow blast waves are reviewed. These are responsible for the afterglow emission from which much of our understanding of gamma-ray bursts derives.

Controlling Release Kinetics of an Adjuvant from a Depot Improves the Efficacy of Local Immunotherapy in Metastatic Cancer

Advanced Science, EarlyView.
We show that intratumoral release of an immunotherapy—CpG —can be tuned with molecular precision by complexing it to an elastin‐like polypeptide (ELP). Injecting ELP‐CpG and an excipient ELP into tumors drives thermally‐triggered phase separation into a micro‐scale “sponge” depot that releases CpG at rates depending on the ELP composition, which ...
