We have evolved as meat eaters, proclaims Patrick Martins, and it's futile to deny it. But, given the destructive forces of the fast-food industry and factory farming, we need to make smart, informed choices about the food we eat and where it comes from. In 50 short chapters, Martins cuts through organized zealotry and the misleading jargon of food labeling to outline realistic steps everyone can take to be part of the sustainable-food movement. With wit, and insight, and no small amount of provocation, The Carnivore's Manifesto is both a revolutionary call to arms and a rollicking good read that will inspire, engage, and challenge anyone interested in the way we eat today.

TASK-1 is a two-pore K + leak channel. The name, TASK-1, stands for TWIK-related acid-sensitive potassium channel 1, and this channel is encoded by the KCNK3 gene. TASK-1 channels are expressed in humans and modulate cell excitability in excitable cells such as neurons, cardiomyocytes, and vascular smooth muscle cells. TASK-1 inhibition is a mechanism of action for some respiratory stimulants, such as doxapram. TASK-1 channels have also been suggested to play a role in circumventing cell apoptosis in a population of non-small-cell lung cancer cells. We propose that the inner vestibule of the TASK-1 channel, a known binding site of known TASK-1 inhibitors, BAY10000493 and BAY2341237, can be exploited via virtual screening to find other novel TASK-1 inhibitors. Our results show that by targeting the inner vestibule site, we found an active TASK-1 inhibitor. We suspect that this region of interest can be further exploited to discover additional TASK-1 inhibitors. Our initial success lends validity to our virtual screening methodology and parameters. In this study, we identified a novel TASK-1 inhibitor, KU124, which we verified using an in vitro assay.

In recent years, sulfamic acid (SA, NH 2 SO 3 H) has emerged as a novel green catalyst for organic synthesis because of several advantages, including its non-volatility, non-hygroscopicity, non-corrosivity, and low cost. This work reports the use of sulfamic acid as a catalyst in the pretreatment of oil with a high content of free fatty acids (10 and 20 % FFA) in ethanol or methanol. The process (esterification reaction) used in the pretreatment of the oil was carried out under a variety of conditions, initial fatty acid content, temperature, type of alcohol, and  % catalyst. The experiments using an NH 2 SO 3 H/ethanol system resulted in a high fatty acid ethyl ester conversion, 88.53 % (±0.95) from an initial acidity of 40 mg KOH/g (20 % FFA), using 8 % NH 2 SO 3 H as the catalyst. According to the results, the methodology using sulfamic acid and ethanol demonstrated elevated potential for a environmentally-friendly means of biodiesel production.

The Environmental Sensitivity Index (ESI) Map is an element to guide the planning of contingency. Road transport is the main vectors in accidents which cause oil spilling in the environment. Since terrestrial environments do not have their environmental sensitivity index, as the marine environment have. Current analysis forwards a proposal for mapping environmental sensitivity to oil and oil derivatives spills in terrestrial environments. Four factors have been included in the Environmental Sensitivity Index Maps: (1) biological resources; (2) socioeconomic mosaic; (3) land cover; (4) Terrestrial Environmental Sensitivity Index (TESI). ESI maps were prepared in five pilot areas for the Rodovia dos Tamoios, state of São Paulo, Brazil, featuring intermediary class TESI, diversity in socio-economic activities, land cover and constant presence of fauna. Adequacy for sensitivity in terrestrial environments triggers the systematization of an efficient, fast and simple production index.

This paper presents an innovative testing framework, testFAILS, designed for the rigorous evaluation of AI Linguistic Systems (AILS), with particular emphasis on the various iterations of ChatGPT. Leveraging orthogonal array coverage, this framework provides a robust mechanism for assessing AI systems, addressing the critical question, “How should AI be evaluated?” While the Turing test has traditionally been the benchmark for AI evaluation, it is argued that current, publicly available chatbots, despite their rapid advancements, have yet to meet this standard. However, the pace of progress suggests that achieving Turing-test-level performance may be imminent. In the interim, the need for effective AI evaluation and testing methodologies remains paramount. Ongoing research has already validated several versions of ChatGPT, and comprehensive testing on the latest models, including ChatGPT-4, Bard, Bing Bot, and the LLaMA and PaLM 2 models, is currently being conducted. The testFAILS framework is designed to be adaptable, ready to evaluate new chatbot versions as they are released. Additionally, available chatbot APIs have been tested and applications have been developed, one of them being AIDoctor, presented in this paper, which utilizes the ChatGPT-4 model and Microsoft Azure AI technologies.

The aim of this investigation was to determine whether fish diversity in headwater streams is influenced by environment, connectivity with large rivers via source-sink dynamics, and/or by an interchange of individuals with other stream assemblages. We measured local diversity using four indices: species richness (SR), functional diversity (FD), taxonomic diversity (TD), and local contribution to beta diversity (LCBD). For each descriptor, we applied a variation partitioning framework based on a partial linear regression, considering environmental variables and distance of headwater streams to the main stem or pairwise distance among streams as predictors. The results indicated that water velocity was positively associated with SR, while FD is positively associated with elevation and channel width, and negatively with conductivity. All diversity indices were significantly associated with distance among streams. SR and TD were both related to spatial filters describing larger scales, while FD was related to smaller scales, and LCBD was related to both smaller and larger scales. These results indicate that differences in SR and TD are greater among distant assemblages, whereas FD and LCBD respond to an interplay between local and regional processes. The variation of the four indices was also explained by the shared component between environment and space but not by the distance of headwater streams to the main stem. Therefore, patterns of local fish diversity seem to be more related to patch dynamics or species sorting, rather than to source-sink dynamics. Strategies to protect assemblages of headwater streams in tropical regions should consider multiple sites rather than single sites to guarantee species dispersal and the preservation of environmental heterogeneity.

Abstract Aim: Chlorophyll-a may be directly influenced by local variables and/or indirectly by land use and cover, once landscape modifications change limnological variables, which in turn affect the primary productivity of aquatic environments, e.g., streams. Therefore, the objective of this study was to determine the relative importance of the local and landscape environmental components and assess the direct and indirect effects of these variables on sestonic chlorophyll-a concentration in 30 Cerrado streams (Santa Teresa River basin). Results All aquatic environments were oligotrophic during the study period. Only the local variables were important to explain chlorophyll-a variation (R2 = 0.27; P = 0.04). In addition, the path analysis showed that all variables used in the analysis influenced chlorophyll-a concentration more directly than indirectly. Conductivity was the most important variable to directly influence chlorophyll-a, followed by turbidity. Conclusion The large amount of remnant native vegetation in the basin indicates that the region studied is well preserved, which may explain the greater importance of local variables and the low effect of the landscape in explaining chlorophyll-a variation. Resumo Objetivo: A clorofila-a pode ser influenciada diretamente por variáveis locais e/ou indiretamente pelo cobertura e uso do solo, uma vez que alterações na paisagem promovem mudanças em variáveis limnológicas, o que por sua vez afeta a produtividade primária de ambientes aquáticos tais como riachos. Portanto, o objetivo deste trabalho foi determinar a importância relativa dos componentes ambientais locais e de paisagem e verificar os efeitos diretos e indiretos dessas variáveis na concentração da clorofila-a planctônica em 30 riachos do Cerrado (Bacia do rio Santa Teresa). Resultados Os ambientes aquáticos durante o período de estudo foram oligotróficos. Somente as variáveis locais foram importantes para explicar a variação da clorofila-a (R2 = 0,27; P = 0,04). Além disso, a análise de caminhos demonstrou que todas as variáveis utilizadas na análise influenciaram mais de forma direta do que indiretamente a concentração de clorofila-a. Diretamente a condutividade foi a variável mais importante, seguida de turbidez. Conclusões A grande proporção de vegetação nativa remanescente na bacia indica que a região de estudo ainda é bastante preservada, o que pode explicar a maior importância das variáveis locais em detrimento do pequeno efeito da paisagem na variação da clorofila-a.
