A Massive Hot Jupiter Orbiting a Metal-rich Early M Star Discovered in the TESS Full-frame Images
The Astronomical Journal, 2023 Observations and statistical studies have shown that giant planets are rare around M dwarfs compared with Sun-like stars. The formation mechanism of these extreme systems has remained under debate for decades. With the help of the TESS mission and ground-

Infrared Non-detection of Fomalhaut b -- Implications for the Planet Interpretation [PDF]
, 2012 The nearby A4-type star Fomalhaut hosts a debris belt in the form of an eccentric ring, which is thought to be caused by dynamical influence from a giant planet companion.

Nanoscale Mapping of the Subcellular Glycosylation Landscape
Advanced Science, EarlyView.Using multiplexed super‐resolution imaging with fluorophore‐labeled lectins, this study reports intracellular glycosylation at the nanoscale across organelles and synaptic specializations. Extending glycan analysis beyond the cell surface, Glyco‐STORM reveals distinct glycosylation nanodomains in the ER, Golgi, lysosomes, and synaptic sites.

Breaking Giant Chains: Early-stage Instabilities in Long-period Giant Planet Systems
The Astrophysical JournalOrbital evolution is a critical process that sculpts planetary systems, particularly during their early stages where planet–disk interactions are expected to lead to the formation of resonant chains.

Advanced Science, EarlyView.The introduction of atomically dispersed Zr‐N moieties adjacent to Fe‐N4 centers forms a bimetallic coordination configuration. This structure modifies the local electronic environment of the Fe sites, weakening the adsorption of OH intermediates, suppressing Fe agglomeration and dissolution, and consequently enhancing both the catalytic activity and ...

Defect‐Engineered Bulk Conversion Anodes for Fast and Temperature‐Adaptive Na+ Storage
Advanced Science, EarlyView.Defect‐engineering has been rationally applied in bulk conversion anodes for sodium ion batteries. The typical carbon‐free/defect‐rich bulk‐Fe7Se8‐x realizes extraordinary fast and temperature‐adaptive sodium ion storage. Various in/ex situ experimental characterizations and DFT calculations verify the peculiar conversion‐type reaction mechanism and ...
