Galactic cosmic rays on extrasolar Earth-like planets: II. Atmospheric implications

, 2016
(abridged abstract) Theoretical arguments indicate that close-in terrestial exoplanets may have weak magnetic fields. As described in the companion article (Paper I), a weak magnetic field results in a high flux of galactic cosmic rays to the top of the ...

Screening and identification of a six-cytokine biosignature for detecting TB infection and discriminating active from latent TB

Journal of Translational Medicine, 2018
Background The early and accurate diagnosis of tuberculosis (TB) is critical for controlling the global TB epidemic. Although early studies have supported the potential role of cytokine biomarkers in blood for the diagnosis of TB, this method requires ...

Fingerprinting Non-Terran Biosignatures [PDF]

Astrobiology, 2018
Most strategies for life detection rely upon finding features known to be associated with terran life, such as particular classes of molecules. But life may be vastly different on other planets and moons, particularly as we expand our efforts to explore ocean worlds like Europa and Enceladus.

Microscale Biosignatures and Abiotic Mineral Authigenesis in Little Hot Creek, California

Frontiers in Microbiology, 2018
Hot spring environments can create physical and chemical gradients favorable for unique microbial life. They can also include authigenic mineral precipitates that may preserve signs of biological activity on Earth and possibly other planets.

A characteristic cerebellar biosignature for bipolar disorder, identified with fully automatic machine learning

IBRO Neuroscience Reports, 2023
Background: Transcriptomic profile differences between patients with bipolar disorder and healthy controls can be identified using machine learning and can provide information about the potential role of the cerebellum in the pathogenesis of bipolar ...

Deciphering Biosignatures in Planetary Contexts [PDF]

Astrobiology, 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 processes would look like ...

Application of Cerebrospinal Fluid Host Protein Biosignatures in the Diagnosis of Tuberculous Meningitis in Children from a High Burden Setting

Mediators of Inflammation, 2019
Background. The diagnosis of tuberculous meningitis (TBM) especially in children is challenging. New tests are urgently needed for the diagnosis of the disease, especially in resource-limited settings. Methods.

Detectors and cooling technology for direct spectroscopic biosignature characterization

, 2016
Direct spectroscopic biosignature characterization (hereafter "biosignature characterization") will be a major focus for future space observatories equipped with coronagraphs or starshades.
