Nurses comprise the largest health professional group in terms of number, and they can be found in almost every health care setting, including homes, schools, work sites, and hospitals. To a large extent, nurses have always been aware of environmental factors when doing their job, but the definition of environmental health nursing is being expanded. Today, in addition to considering the possibi...

In the last decades, substantial changes have occurred regarding what scientists consider the limits of habitable environmental conditions. For every extreme environmental condition investigated, a variety of microorganisms have shown that not only can they tolerate these conditions, but that they also often require these extreme conditions for survival. Microbes can return to life even after h...

Organisms with environmental sensors that guide survival are considered more likely to be favored by natural selection if they possess more accurate sensors. In this paper, we develop a theoretical model which shows that under certain conditions of environmental stochasticity, selection actually favors sensors of lower accuracy. An analogy between this counter-intuitive phenomenon and the well-...
