Here, we describe the characterization of a range of biosignatures within potentially analogous sulfur deposits from the surface of an Arctic glacier at Borup Fiord Pass to evaluate whether...

In this study, we performed eldwork in the subarctic and fi applied a protocol using UV-Vis spectroscopic equipment (in situ and in the laboratory) to search for biosignatures in samples …

Here, we describe the characterization of a range of biosignatures within potentially analogous sulfur deposits from the surface of an Arctic glacier at Borup Fiord Pass to evaluate whether …

In this report, we propose innovative instruments and instrument payloads designed to detect microbial life on Mars while addressing its unique, challenging conditions.

Our study provides a clear path for astrobiological exploration on a range of spatial scales, which has been tested and applied at a specific Mars analogue site.

We compare features with random forest importance, and we train a classifier that discriminates between biotic and abiotic samples with high accuracy. These ML-trained ocean-world analog …

To estimate aggregate preferences for the 2024 U.S. presidential election candidates, we collect and analyze secret-shared data from nearly 8000 users from August 2024 through February …

Mar 11, 2025 · In this study, we developed an interpretable ML approach for biosignature detection that can detect statistical interactions, disentangle biotic mimicry, and evaluate the …
