Get PDFMy Octopus Teacher combines a carefully structured love story with astonishing information about undersea life, documenting a year of encounters between a photographer and an octopus. It is important as a non-standard love story and as a reflection on the possibility of deep connection with non-human creatures

Onset of the Messinian Salinity Crisis: Insights from molecular organic geochemistry
Get PDFThe Messinian Salinity Crisis (MSC) generated extensive anoxic sediments under the evaporitic deposits in marginal Mediterranean basins. In an interdisciplinary approach combining field work with multiple laboratory techniques, the oil source rock potential and biomarkers of pre-evaporitic Messinian sediments from the Caltanissetta Basin (Sicily) were evaluated using Rock-Eval pyrolysis, gas chromatography-mass spectrometry, isotopic analysis and optical and electron microscopy. Organic-rich samples from the 45 m Serra Pirciata section consist of cycles of diatomaceous and carbonate layers alternating with organic shales of variable TOC. The organic matter is mostly optically amorphous, increasing in content upwards in the section. Of the 43 samples analyzed within the section, an especially organic- and sulfur-rich interval shows TOC values up to 10%, and oil generation potential (Rock-Eval S2) up to 75 mg HC/g rock. Samples show Rock-Eval Hydrogen Indices (HI) up to ca. 800 mg HC/g TOC, but most fall in the range of 300-600 mg HC/ g TOC, indicating type II kerogen. Within this section, a specific interval is especially remarkable for its unusual biomarker assemblage, having abundant sulfur compounds including isoprenoid, steroid, and hopanoid thiophenes and thiolanes, as well as microscopic sponge fossils. We propose that this organic-rich interval with its distinctive biomarkers represents an initial episode of basin restriction and, based on cyclostratigraphic interpretations, constitutes a non-evaporitic record of the onset of the MSC in the deeper part of the Caltanissetta Basin, where gypsum deposits were initially absent. If the depocenter of the Caltanissetta Basin is an analog for the deep Mediterranean basin, these results suggest that a large volume of organic matter of bacterial origin accumulated in the deep Mediterranean prior to evaporitic deposition
Heart Rate Variability Following Blood Flow Restriction Resistance Exercise and Traditional Resistance Exercise in Trained Men and Women
No full textAutonomic nervous system responses are attenuated following blood flow restriction (BFR) resistance exercise vs traditional resistance exercise (TRE) in men, but women’s responses are unknown. The purpose of this investigation is to compare the effects of a single BFR vs TRE session on HRV. Thirty-nine adults (M=20, W=19, age: 23±4yrs, body mass: 72.3±13.2kg, height: 169±9cm) participated in the study. Barbell back squat 1 repetition maximum (1RM) testing was performed followed by two randomized and counterbalanced exercise visits ≥48hrs apart (BFR: 4 sets, 30-15-15-15 repetitions, 30% 1RM, 60s rest; TRE: 4 sets x 10 repetitions, 70% 1RM, 60s rest). Pre- and post-exercise resting electrocardiograms were analyzed using heart rate variability (HRV) normalized units for low frequency (LF), high frequency (HF), and LF/HF. Two-way repeated measures ANOVA’s with sex as a between-subjects effect were analyzed (alpha p\u3c 0.05). Both LF and HF displayed interaction effects (both p\u3c 0.05) with no effect or interaction with sex (all p\u3e0.05). Post-hoc testing found that LF increased and HF decreased post exercise, but with greater effects in the TRE condition (all p\u3c 0.05). LF/HF also increased post exercise, and there was a sex by time interaction (all p\u3c 0.05). Post-hoc testing found greater increases in LF/HF post-exercise in men than women (p\u3c 0.05) across exercise conditions. Both TRE and BFR increased sympathetic activity and decreased parasympathetic activity HRV indices, and the changes were attenuated for BFR in both sexes. However, men have a greater shift towards sympathetic dominance independent of exercise type. These changes in HRV indices may have beneficial applications for exercise training/recovery when trying to reduce autonomic stress
