title: Extended Longevity Photoactivated Surface Enhanced Raman Spectroscopy for the Detection of Biosignatures on Icy Worlds and Martian Polar Caps

description: Surface Enhanced Raman Spectroscopy (SERS) has traditionally not been considered for planetary sciences due to issues associated with SERS substrate degradation and spectra reproducibility. Here we present ongoing work on the Compact Integrated Raman Spectrometer (CIRS) instrument developed for the Europa Lander Mission concept [1], [2], which incorporates SERS capability into the green-wavelength Raman system in order to allow detection of biosignatures at extremely low concentrations. In this work we optimize a SERS method based on chemically stable AgCl precursor coating [3], which is reduced to SERS-active Ag nanoparticles (NPs) in-situ, thus eliminating any potential degradation of the SERS-active AgNPs during transit. We use the modified AgCl coating to detect biosignatures relevant for the search for extraterrestrial life, evaluate the detection limit and characterize the stability and reproducibility of the resulting spectra. To assess the impact of environmental conditions on Icy Worlds and Mars, we also investigate the effect of salts and varying pH. The results show L-Histidine can be detected 10nM and BPE as low as 10-24M, which is within the estimated biomolecule concentration range for Icy Worlds [2], [4], [5]. Furthermore, the presence of salts significantly enhances the SERS signal, which makes this method particularly favourable for detecting in salty brines, such as on Ocean Worlds or Mars. This method thus greatly enhances the scientific capabilities of the CIRS instrument for the exploration of Icy Worlds and Martian polar caps. Furthermore, the SERS coating is applied to the sample cup at little additional cost or complexity and requires no sample preparation.

title: AlphaFold Prediction of Structural Ensembles of Disordered Proteins

description: Deep learning methods of predicting protein structures have reached an accuracy comparable to that of high-resolution experimental methods. It is thus possible to generate accurate models of the native states of hundreds of millions of proteins. An open question, however, concerns whether these advances can be translated to disordered proteins, which should be represented as structural ensembles because of their heterogeneous and dynamical nature. To address this problem, we introduce the AlphaFold-Metainference method to use AlphaFold-derived distances as structural restraints in molecular dynamics simulations to construct structural ensembles of ordered and disordered proteins. The results obtained using AlphaFold-Metainference illustrate the possibility of making predictions of the conformational properties of disordered proteins using deep learning methods trained on the large structural databases available for folded proteins.

title: Research data for Seasonality, long-term trends and co-occurrence of sharks in a top predator assemblage

description: Data consist of occurrence records for sharks and other marine fauna on 1,917 scuba dives at Protea Banks, South Africa, between 2013 and 2019.<b>Abstract</b>Shark predator assemblages play an important role in the top-down processes that are vital to marine ecosystem functioning. Spatiotemporal partitioning of sharks due to seasonal movements or population changes may have significant consequences for the top-down effects, depending on the level of functional redundancy in the assemblage. However, long-term, co-occurrence data for sharks is hard to obtain and often lacking. Here we use citizen science data collected by professional scuba guides over seven years to model the seasonal and across-year temporal dynamics, and intraguild and trophic co-occurrence interactions, for an assemblage of six shark top predators (Carcharhinus leucas, Carcharhinus obscurus, Carcharhinus limbatus, Carcharias taurus, Sphyrna lewini, and Galeocerdo cuvier). The presence of all six study species were clearly seasonal and, in most cases, exhibited positive long-term trends across years. The seasonalities observed, combined with temporal co-occurrence analysis, suggests that dietary redundancy but temporal complementarity exists amongst the top predator assemblage. The study shows citizen science data collected by professional non-scientists is a cost-effective method for monitoring top predators and may be able to highlight potential predator-prey interactions worthy of further investigation.

title: Experimental Study on the Effects of Ambient Light on the Precision of Short-Range Near-Infrared LiDAR Systems

description: This work investigates the influence of ambient light noise on the performance of an 850 nm single-point light detection and ranging (LiDAR) system, specifically focusing on targets with varying reflectivity and range. A commercial LiDAR module was used, in conjunction with six distinct specimens, to collect and analyze spatial-temporal data over a measurement range of up to 4 meters. The spatial-temporal analysis of quasi-static experimental data reveals that luminous intensity and range critically affect LiDAR accuracy. At the same time, reflectivity consistently impacts LiDAR measurements irrespective of their magnitude but varies with material type. The relative error in measurement, reflectivity of material, and luminous intensity of the light noise exhibit near-normal distributions with asymmetrical tails. Statistically significant differences between the distributions of relative error, reflectivity, and luminous intensity highlight the complex interactions influencing LiDAR performance. These findings offer essential insights for the design and optimization of LiDAR systems, ensuring accurate environmental sensing under variable ambient light conditions, and they affirm the possibility of developing transferable models.
