Alternative Methylated Biosignatures. I. Methyl Bromide, a Capstone Biosignature [PDF]

open access: yesAstrophysical Journal, 2022
The first potential exoplanetary biosignature detections are likely to be ambiguous due to the potential for false positives: abiotic planetary processes that produce observables similar to those anticipated from a global biosphere.

Identification of serum tRNA-derived small RNAs biosignature for diagnosis of tuberculosis [PDF]

open access: yesEmerging Microbes and Infections
The tRNA-derived small RNAs (tsRNAs) are a new class of non coding RNAs, which are stable in body fluids and can be used as potential biomarkers for disease diagnosis.

Identification of an immune-metabolic biosignature linking depressive symptoms and breast cancer in a clinical population [PDF]

open access: yesTranslational Psychiatry
Breast cancer (BC) is a leading cause of mortality among women. Comorbidity with mood disorders is a condition either disregarded or underdiagnosed in BC patients, but that might ultimately jeopardize health trajectories.

Metabolomic Profile of the Fungus Cryomyces antarcticus Under Simulated Martian and Space Conditions as Support for Life-Detection Missions on Mars

open access: yesFrontiers in Microbiology, 2022
The identification of traces of life beyond Earth (e.g., Mars, icy moons) is a challenging task because terrestrial chemical-based molecules may be destroyed by the harsh conditions experienced on extraterrestrial planetary surfaces.
