Biogenic Metal Nanoparticles: A New Approach to Detect Life on Mars?
Life, 2020 Metal nanoparticles (MNPs) have been extensively studied. They can be produced via different methods (physical, chemical, or biogenic), but biogenic synthesis has become more relevant, mainly for being referred by many as eco-friendly and more ...

Using retinal electrophysiology toward precision psychiatry
European Psychiatry, 2022 Precision medicine in psychiatry is based on the identification of homogeneous subgroups of patients with the help of biosignatures—sets of biomarkers—in order to enhance diagnosis, stratification of patients, prognosis, evaluation, and prediction of ...

Advanced Science, EarlyView.A programmable 3D Neuron‐Injury‐on‐a‐Chip platform integrates multiaxial mechanical loading with ultrasensitive electrochemical biosensing to decode neuronal responses in real time. By mimicking physiologically relevant extension–torsion forces, the system reveals load‐specific biomarker trajectories (T‐Tau, NFL), gene regulation, and apoptosis.

Biosignature hide and seek [PDF]
Nature 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.

Evidence of microbial activity from a shallow water whale fall (Voghera, northern Italy) [PDF]
, 2012 The fossil bones, associated carbonate cements and enclosing concretion of a Miocene mysticete from inner shelf deposits (Monte Vallassa Formation, northern Italy) were analyzed for evidence of microbial activity. Optical and scanning electron microscopy,

Journal of Raman Spectroscopy, EarlyView.Simulated planetary gas detection using the A.C.M.E. chamber and a novel hollow‐core fiber Raman sensor. Controlled atmospheric mixtures were used to evaluate the sensor’s performance, demonstrating its capability to detect gases such as CO₂, O₂, and N₂. The results support the applicability of the HCF‐based Raman sensor in future planetary exploration

Interpretable Differential Abundance Signature (iDAS)
Small Methods, EarlyView.iDAS is an ANOVA‐based framework that enhances the interpretability of differential abundance signatures in single‐cell and spatial omics data. It provides a coherent and interpretable framework for grouping gene‐level associations in complex experimental designs.

Evaluating Biosignatures for Life Detection [PDF]
Astrobiology, 2020 Conceptual frameworks are developed for evaluating the ability of different biosignatures to provide evidence for the presence of life in planned missions or observational studies. The focus is on intrinsic characteristics of biosignatures in space environments rather than on their detection, which depends on technology. Evaluation procedures are drawn
