GOLD Observations of Thermospheric Neutral Temperature Variability During the 14 October 2023 Annular Solar Eclipse

open access: yesGeophysical Research Letters
The 14 October 2023 annular solar eclipse was visible from the US Pacific coast to Brazil's east coast. NASA's Global‐scale Observations of Limb and Disk (GOLD) mission observed the first synoptic thermospheric temperature changes from a geo‐stationary ...

The dynamic effects of solar eclipses of October 25, 2022, and October 14, 2023, on GPS-derived total electron content

open access: yesGeodesy and Geodynamics
This study analyzes total electron content (TEC) variations during two solar eclipse events that occurred on October 25, 2022, and October 14, 2023. The solar eclipse of October 25, 2022, was a partial solar eclipse, while the eclipse of October 14, 2023,

Unraveling the Heterogeneity of Cargo Distribution in the Exogenous Association of Proteins With Extracellular Vesicles

open access: yesAdvanced Healthcare Materials, EarlyView.
We characterized the distribution of cargo proteins associated with extracellular vesicles using various exogenous loading methods. In all cases, single‐particle analysis revealed that the distribution of protein content per EV is heterogeneous, following an exponential decay function.

A Human Neural Tube Model Using 4D Self‐Folding Smart Scaffolds

open access: yesAdvanced Healthcare Materials, EarlyView.
Induced pluripotent stem cells (iPSCs) exhibit features comparable to the inner cell mass of the human embryo. iPSCs are applied to a novel self‐folding 4D‐Neural Tube (4D‐NT) structure that mimics the neurulation process. This 4D‐NT model recapitulates early events of human neural development and represents a platform to explore neurodevelopmental ...

Studying the Radio Eclipse of Spider Pulsar J1816+4510 with the FAST

open access: yesThe Astrophysical Journal
We report on the radio eclipse properties of spider pulsar J1816+4510 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The high-sensitivity FAST observations will allow us to probe much deeper into the eclipse region of this pulsar

A Human Kidney Tubuloid Model of Repeated Cisplatin‐Induced Cellular Senescence and Fibrosis for Drug Screening

open access: yesAdvanced Healthcare Materials, EarlyView.
Replicating aging and senescence‐related pathophysiological responses in kidney organoids remains a significant challenge. Human adult renal tubular organoid, tubuloids, are successfully developed recapitulating cellular senescence that is the central pathophysiological mechanism of chronic kidney disease (CKD).

Ultrasound‐Triggered Gelation for Restoring Biomechanical Properties of Degenerated Functional Spinal Units

open access: yesAdvanced Healthcare Materials, EarlyView.
This study introduces an innovative approach to treating intervertebral disc degeneration using ultrasound‐triggered in situ hydrogel formation. Proof‐of‐concept experiments using optimized biomaterial and ultrasound parameters demonstrate partial restoration of biomechanical function and successful integration into degenerated disc tissue, offering a ...

Few‐Layered Conductive Graphene Foams for Electrical Transdifferentiation of Mesenchymal Stem Cells Into Schwann Cell‐Like Phenotypes

open access: yesAdvanced Healthcare Materials, EarlyView.
Few‐layered three dimansional conductive graphene foams are promising cytocompatible platforms to transdifferentiate mesenchymal stem cells into Schwann cell‐like phenotypes using electrical and microstructural cues. Applied electrical stimulation conditions resulted in activation of MAPK, neurotrphin and RAS signaling pathways that led to upregulation
