Habitability on Early Mars and the Search for Biosignatures with the ExoMars Rover [PDF]

open access: yes, 2017
The second ExoMars mission will be launched in 2020 to target an ancient location interpreted to have strong potential for past habitability and for preserving physical and chemical biosignatures (as well as abiotic/prebiotic organics).

False Biosignatures on Mars: Anticipating Ambiguity [PDF]

open access: yes, 2021
It is often acknowledged that the search for life on Mars might produce false positive results, particularly via detections of objects, patterns or substances that resemble the products of life in some way but are not biogenic.

Toward a Unified Biosignature for Tuberculosis [PDF]

open access: yesCold Spring Harbor Perspectives in Medicine, 2014
Accurate and rapid diagnosis of active tuberculosis (TB) disease is still hampered by inadequate tools. Although current assays relying on single-marker readouts mostly display inadequate sensitivity and/or specificity, host-related multimarker signatures are especially poorly developed. As a consequence, research programs have been initiated to search

A review of exoplanetary biosignatures [PDF]

open access: yesPhysics Reports, 2017
We review the field of exoplanetary biosignatures with a main focus upon atmospheric gas-phase species. Due to the paucity of data in Earth-like planetary atmospheres a common approach is to extrapolate knowledge from the Solar System and Early Earth to Earth-like exoplanets. We therefore review the main processes (e.g.

Deciphering Biosignatures in Planetary Contexts [PDF]

open access: yesAstrobiology, 2019
Microbial life permeates Earth's critical zone and has likely inhabited nearly all our planet's surface and near subsurface since before the beginning of the sedimentary rock record. Given the vast time that Earth has been teeming with life, do astrobiologists truly understand what geological features untouched by biological ...

Discriminating between extinct and extant life detection: implications for future Mars missions

open access: yesFrontiers in Astronomy and Space Sciences
The search for biosignatures on Mars has been a high priority for astrobiology. The approach to detecting putative biosignatures has largely been focused on chemical analyses targeting predominantly extinct life.

Biosignature hide and seek [PDF]

open access: yesNature Astronomy, 2018
A new model predicts locations on the surface of radiation-blasted Europa, the ocean moon of Jupiter, where biochemical signatures of life emergent from the subsurface ocean might survive long enough for detection on the moon's changing surface.

Hierarchical interactions model for predicting Mild Cognitive Impairment (MCI) to Alzheimer's Disease (AD) conversion.

open access: yesPLoS ONE, 2014
Identifying patients with Mild Cognitive Impairment (MCI) who are likely to convert to dementia has recently attracted increasing attention in Alzheimer's disease (AD) research.
