The first case of bilateral gynandromorphic plumage type in the bearded reedling Panurus biarmicus
The European Zoological Journal, 2023 Bilateral gynandromorphism is a condition in which an individual has both male and female phenotypes distributed symmetrically on the body. We describe the first case of a likely gynandromorphic bearded tit, which was trapped in Poland.

Advanced Functional Materials, EarlyView.Photothermal, macroporous lignin‐based cryogels are engineered to convert sunlight into low‐grade heat. Integrated as stacked beds in a drum‐type device, a thin copper interlayer transfers waste heat between beds, enabling interlayer heat recovery and continuous solar cycling.

Bio‐Inspired Multimodal Hardware Front‐End Enabled by 2D Floating‐Gate Memory for UAV Perception
Advanced Functional Materials, EarlyView.A MoS2/h‐BN /graphene floating‐gate memory underpins a bio‐inspired multimodal front end that integrates visual, inertial, and airflow cues. A 4 × 4 FG memory array encodes temporal intensity differences, while IMU‐ and airflow‐driven threshold modulation suppresses self‐motion artifacts, enabling fast, low‐power, robust autonomous UAV tracking and ...
