Men display faster in male-biased mating contexts.

Across diverse species with sexual reproduction, typically the more male-biased the adult sex ratio (ASR), the greater the investments by the more populous males in the rarer females who hold greater bargaining power in a mating context. Relatively few studies have examined this effect in humans however, and almost none involve observations of actual male investment in a potential mating context. Here, we present one of the first studies to observe investments of men in a potential mating context under differing ASRs.

Surface soil-dust contamination of Phalaris arundinacea grown on former lead mine sites: Implications for biomass use, phytoremediation and phytomanagement.

This study evaluated the contribution of soil dust deposited on the surface of reed canary grass (Phalaris arundinacea) grown on historic lead (Pb) mine sites to the overall contamination of the biomass, with implications for phytoremediation, valorization and utilization. By applying a novel combination of imaging of plant material using X-ray computed tomography (XCT) and scanning electron microscopy (SEM), with washing experiments and bulk analysis, the research aimed to distinguish between (a) Pb uptake through biological processes (phyto-extraction), and (b) surficial dust and physical entrapment of Pb-rich dust on plants cultivated in contaminated soils (surface-contamination). The study established the presence and distribution of Pb-rich particles, which were difficult to remove even by means of sequential washing in 1 M hydrochloric acid and surfactant.

Rapid Onsite Evaluation: A Prospective Observational Study of Endobronchial Ultrasound-Guided Transbronchial Needle Aspirates to Expedite Diagnosis.

Biomedical scientists (BMS) can report sample adequacy during EBUS TBNA using rapid on-site evaluation (ROSE). Despite being able to report exfoliative samples such as pleural fluid cytology and bronchial washings, they are usually not permitted to offer a preliminary diagnostic impression of EBUS TBNA samples. Experienced biomedical scientists can provide a reliable diagnostic impression during ROSE for EBUS samples, with sensitivity and specificity comparable to cytopathologist reporting.
