Accumulation of non-outer segment proteins in the outer segment underlies photoreceptor degeneration in Bardet–Biedl syndrome

Proceedings of the National Academy of Sciences of the United States of America, 2015
Significance The photoreceptor outer segment (OS) is a cellular compartment that senses light in the eye. Structural and functional defects in the OS are common causes of inherited blindness.

Retina‐Inspired Bi‐Based Terahertz Photonic Neuromorphic Devices

Advanced Science, EarlyView.
Combined with effective band alignment and substrate engineering, bismuth materials are introduced to form terahertz photonic bio‐inspired devices with picosecond short‐term plasticity to enable multi‐scene visual perception. Thus obtained hardware through the terahertz optical neural network (THz‐ONN) demonstrates high recognition accuracy, providing ...

Emerging Molecular Links Between Plant Photomorphogenesis and Virus Resistance

Frontiers in Plant Science, 2020
Photomorphogenesis refers to photoreceptor-mediated morphological changes in plant development that are triggered by light. Multiple photoreceptors and transcription factors (TFs) are involved in the molecular regulation of photomorphogenesis.
