Small Extracellular Vesicles from Neural Cells: Physiological and Pathological Roles, and Potential in Neurodegenerative Therapy

Advanced Healthcare Materials, EarlyView.
Neural cell–derived small extracellular vesicles (sEVs) are emerging as pivotal mediators in neurodegenerative diseases, exerting both pathogenic and therapeutic functions. This review synthesizes current evidence on how sEVs from distinct neural cell types regulate neurodegeneration, neuroprotection, biomarker discovery, and targeted drug delivery ...

Micro- to nano-sized solid inclusions in magnetite record skarn reactions [PDF]

European Journal of Mineralogy
Magnetite is a widespread ore mineral in skarn systems and usually hosts a wide variety of inclusions. Micro- to nano-sized solid inclusions in magnetite are unique tools to track the evolutionary processes of its host mineral and, subsequently, to ...

Controllable Dynamic Mechanical Cell Stimulation using Magnetically Actuated Artificial Cilia

Advanced Healthcare Materials, EarlyView.
This paper introduces a platform based on magnetic artificial cilia for providing controllable dynamic mechanical stimulation to single cells, suitable for investigating large cell populations and enabling live cell imaging. Proof‐of‐principle experiments show that cell morphology is strongly influenced by the artificial cilia, that cellular forces can

Coherent generation of symmetry-forbidden phonons by light-induced electron-phonon interactions in magnetite

, 2017
Symmetry breaking across phase transitions often causes changes in selection rules and emergence of optical modes which can be detected via spectroscopic techniques or generated coherently in pump-probe experiments.

Avian magnetoreception: elaborate iron mineral containing dendrites in the upper beak seem to be a common feature of birds [PDF]

, 2010
The magnetic field sensors enabling birds to extract orientational information from the Earth’s magnetic field have remained enigmatic. Our previously published results from homing pigeons have made us suggest that the iron containing sensory dendrites ...
