Ufmylation‐Deficient DDRGK1 Ameliorates Obesity by Inhibiting FASN‐Mediated Adipocyte Lipogenesis

Advanced Science, EarlyView.
DDRGK1 regulates de novo lipogenesis via stabilization of fatty acid synthase (FASN). DDRGK1‐mediated UFMylation of FASN prevents its ubiquitin–proteasomal degradation. Reduced DDRGK1 expression or mutation at the key UFMylation site enhances FASN degradation and suppresses fatty acid synthesis (FAS), resulting in smaller adipocytes and improved ...

Impact of Biomimetic Pinna Shape Variation on Clutter Echoes: A Machine Learning Approach

Advanced Intelligent Systems, EarlyView.
Bats with dynamic ear structures navigate dense, echo‐rich environments, yet the echoes they receive are highly random. This study shows that machine learning can reliably detect structural signatures in these seemingly chaotic biosonar signals. The results open new directions for biologically inspired sensing, where time‐varying receiver shapes ...
