Glooby est une petite pieuvre, très tranquille, qui se faufile entre les cailloux, qui joue à cache-cache avec les anémones, et à Pierre-feuille-ciseaux avec les crabes. Elle aime bien manger du plancton, ou des petits bouts de crevettes avec un peu de salicorne. Elle n'a pas du tout envie que les groupes industriels internationaux d'exploitation des fonds marins viennent tout saccager pour extraire des nodules métalliques et faire des téléphones qui rendent débiles la moitié de l'humanité. Elle prépare ses pièges !

The impact of lung parenchyma attenuation on nodule volumetry in lung cancer screening - Insights into Imaging

Background Recent recommendations for lung nodule management include volumetric analysis using tools that present intrinsic measurement variability, with possible impacts on clinical decisions and patient safety. This study was conducted to evaluate whether changes in the attenuation of the lung parenchyma adjacent to a nodule affect the performance of nodule segmentation using computed tomography (CT) studies and volumetric tools. Methods Two radiologists retrospectively applied two commercially available volumetric tools for the assessment of lung nodules with diameters of 5–8 mm detected by low-dose chest CT during a lung cancer screening program. The radiologists recorded the success and adequacy of nodule segmentation, nodule volume, manually and automatically (or semi-automatically) obtained long- and short-axis measurements, mean attenuation of adjacent lung parenchyma, and presence of interstitial lung abnormalities or disease, emphysema, pleural plaques, and linear atelectasis. Regression analysis was performed to identify predictors of good nodule segmentation using the volumetric tools. Interobserver and intersoftware agreement on good nodule segmentation was assessed using the intraclass correlation coefficient. Results In total, data on 1265 nodules (mean patient age, 68.3 ± 5.1 years; 70.2% male) were included in the study. In the regression model, attenuation of the adjacent lung parenchyma was highly significant (odds ratio 0.987, p < 0.001), with a large effect size. Interobserver and intersoftware agreement on good segmentation was good, although one software package performed better and measurements differed consistently between software packages. Conclusion For lung nodules with diameters of 5–8 mm, the likelihood of good segmentation declines with increasing attenuation of the adjacent parenchyma.

This is a polymetallic nodule, about the size of a potato, formed over ~2 millions years at the seabed. This is what the fuss is about. This environment changes incredibly slowly, and the plumes of sediment thrown up by mining would spread and settle on distant seabed. But these ecosystems only form where the natural sediment from above is utterly minuscule. Most of the creatures found with the nodules are singletons - just one of their species. #ocean #seabed #nodule

Undersea nodule mining might have a radioactive problem

Metallic nodules on the seafloor could pose a headache for mining companies and regulators due to their high levels of radioactivity, according to German
