The emergence of bacterial pathogens resistant to all known antibiotics is a global health crisis. Adding to this problem is that major pharmaceutical companies have shifted away from antibiotic discovery due to low profitability. As a result, the pipeline of new antibiotics is essentially dry and many bacteria now resist the effects of most commonly used drugs. To address this global health concern, citizen science through the Small World Initiative (SWI) was formed in 2012. As part of SWI, students isolate bacteria from their local environments, characterize the strains, and assay for antibiotic production...

V Re, E Sacchi
Salinization and nitrate pollution are generally ascertained as the main issues affecting coastal aquifers worldwide. In arid zones, where agricultural activities also result in soil salinization, both phenomena tend to co-exist and synergically contribute to alter groundwater quality, with severe negative impacts on human populations and natural ecosystems' wellbeing. It becomes therefore necessary to understand if and to what extent integrated hydrogeochemical tools can help in distinguishing among possible different salinization and nitrate contamination origins, in order to provide adequate science-based support to local development and environmental protection...

Gilberto Pérez-Campos
Ontological issues have a bad reputation within mainstream psychology. This paper, however, is an attempt to argue that ontological reflection may play an important role in the development of cultural psychology. A cross-reading of two recent papers on the subject (Mammen & Mironenko, Integrative Psychological and Behavioral Science, 49(4), 681-713, 2015; Simão Integrative Psychological and Behavioral Science, 50, 568-585, 2016), aimed at characterizing their respective approaches to ontological issues, sets the stage for a presentation of Cornelius Castoriadis' ontological reflections...

Aquatic systems can be subjected to multiple stressors, including pollutant cocktails and elevated temperature. Evaluating the combined effects of these stressors on organisms is a great challenge in environmental sciences. To the best of our knowledge, this is the first study to assess the molecular stress response of an aquatic fish species subjected to individual and combined pesticide mixtures and increased temperatures. For that, goldfish (Carassius auratus) were acclimated to two different temperatures (22 and 32°C) for 15 days...

A key goal for livestock science is to ensure that food production meets the needs of an increasing global population. Climate change may heighten this challenge through increases in mean temperatures and in the intensity, duration, and spatial distribution of extreme weather events, such as heat waves. Under high ambient temperatures, livestock are expected to decrease dry matter intake (DMI) to reduce their metabolic heat production. High yielding dairy cows require high DMI to support their levels of milk production, but this may increase susceptibility to heat stress...

US Presidents make their mark on health, for better or worse. Donald Trump campaigned on a populist platform to "make America great again". While the actual policies his administration will pursue-and the priority he will place on each of them-remain in many ways uncertain, both his statements and his nominations for key government posts suggest that his presidency could have profound implications for health. His proposal to repeal and replace the Affordable Care Act with a "better reform", his stance on reproductive rights, and his approaches to other areas, such as science policy and climate change, coupled with his stated intention to put "America first" are creating anxiety and uncertainty about America's domestic health policies and its global leadership role in areas such as security and development...

The static levels of proteins are the net results of their production and clearance regulated by the activities of proteins involved in their synthesis, degradation, and transportation. Therefore, the information on the rates of protein synthesis and clearance is needed to understand the underlying dynamic nature of a proteome. In this chapter, the experimental technique, we use in our laboratory for monitoring the synthesis of individual proteins in Caenorhabditis elegans (C. elegans) is described. The technique utilizes a preisotopically labeled amino acid ((13)C6-Lys) as a precursor for protein synthesis and monitors the kinetics of the precursor incorporation into the newly synthesized proteins...
