Data from: Pushing Raman spectroscopy over the edge: purported signatures of organic molecules in fossil animals are instrumental artefacts
<p>Widespread preservation of fossilized biomolecules in many fossil animals has recently been reported in six studies, based on Raman microspectroscopy. Here, we show that the putative Raman signatures of organic compounds in these fossils are actually instrumental artefacts resulting from intense background luminescence. Raman spectroscopy is based on the detection of photons scattered inelastically by matter upon its interaction with a laser beam. For many natural materials, this interaction also generates a luminescence signal that is often orders of magnitude more intense than the light produced by Raman scattering. Such luminescence, coupled with the transmission properties of the spectrometer, induced quasi-periodic ripples in the measured spectra that have been incorrectly interpreted as Raman signatures of organic molecules. Although several analytical strategies have been developed to overcome this common issue, Raman microspectroscopy as used in the studies questioned here cannot be used to identify fossil biomolecules.</p>

IODP Expedition 366 Rig instrumentation
<p>Operational rig information data were measured using a variety of sensors and compiled using the RigWatch software package. Approximately 50 channels of drilling/coring data are captured in real time during the expedition. Data are presented as ASCII files extracted from the proprietary RigWatch data files and are presented by expedition. RigWatch data in time or depth domain can be imported into graphics and analysis programs to be merged and correlated with core physical properties data to enhance assessment of poor core recovery intervals.</p>

Development of low-cost instrumentation for single point autofluorescence lifetime measurements
<p>Dataset used for analysis in the paper. ABSTRACT: Autofluorescence lifetime measurements, which can provide label-free readouts in biological tissues, contrasting e.g. different types and states of tissue matrix components and different cellular metabolites, may have significant clinical potential for diagnosis and to provide surgical guidance. However, the cost of the instrumentation typically used currently presents a barrier to wider implementation. We describe a low-cost single point time-resolved autofluorescence instrument, exploiting modulated laser diodes for excitation and FPGA-based circuitry for detection, together with a custom constant fraction discriminator. Its temporal accuracy is compared against a “gold-standard” instrument incorporating commercial TCSPC circuitry by resolving the fluorescence decays of reference fluorophores presenting single and double exponential decay profiles. To illustrate the potential to read out intrinsic contrast in tissue, we present preliminary measurements of autofluorescence lifetime measurements of biological tissues <em>ex vivo.</em> We believe that the lower cost of this instrument could enhance the potential of autofluorescence lifetime metrology for clinical deployment and commercial development.</p>

The many faces of early life adversity - Content overlap in validated assessment instruments as well as in fear and reward learning research
<p>The precise assessment of childhood adversity is crucial for understanding the impact of aversive events on mental and physical development. However, the plethora of assessment tools currently used in the literature with unknown overlap in childhood adversity types covered hamper comparability and cumulative knowledge generation. In this study, we conducted two separate item-level content analyses of in total 35 questionnaires aiming to assess childhood adversity. These include 13 questionnaires that were recently recommended based on strong psychometric properties as well as additional 25 questionnaires that were identified through a systematic literature search. The latter provides important insights into the actual use of childhood adversity questionnaires in a specific, exemplary research field (i.e., the association between childhood adversity and threat and reward learning). Of note, only 3 of the recommended questionnaires were employed in this research field. Both item-wise content analysis illustrate substantial heterogeneity in the adversity types assessed across these questionnaires and hence highlight limited overlap in content (i.e., adversity types) covered by different questionnaires. Furthermore, we observed considerable differences in structural properties across all included questionnaires such as the number of items, age ranges assessed as well as the specific response formats (e.g., binary vs. continuous assessments, self vs. caregiver). We discuss implications for the interpretation, comparability and integration of the results from the existing literature and derive specific recommendations for future research. In sum, the substantial heterogeneity in the assessment and operationalization of childhood adversity emphasizes the urgent need for theoretical and methodological solutions to promote comparability, replicability of childhood adversity assessment and foster cumulative knowledge generation in research on the association of childhood adversity and physical as well as psychological health.</p>
