Resident Space Object Classification from Light Curves with Deep Learning [PDF]
, 2023 In this study, a novel data-driven pipeline is suggested for classifying resident space objects (RSO) from photometric light curve data. The latter was extracted from the MiniMega-TORTORA (MMT) monitoring system.

Resident Space Object (RSO) Tracking in Space-Based, Low Resolution, Non-Constant-Attitude Imagery
Remote SensingResident Space Objects (RSOs) are a collection of both man-made and natural objects in near-Earth space. Given their large orbital velocities and rapidly increasing quantity, they pose a collision threat to space assets, necessitating better Space ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
