Moisture derived from underground water sources sustains one of world's oldest and most biologically diverse deserts

Fog, seen here receding in the morning, comes and goes quietly in the Namib Desert. The ocean is not the sole source of the fog that sustains life for numerous plants and animals living in Africa's coastal Namib Desert. The fog also comes from groundwater and other sources, report ecohydrologists supported by the National Science Foundation (NSF) and affiliated with Indiana University-Purdue University Indianapolis (IUPUI). The scientists conducted the research in one of the world's oldest and most biologically diverse deserts. Their results are published today in the journal Science Advances. Today on World Water Day -- and in fact every day -- water sources are an important consideration for society. To develop ecological models of arid environments, scientists say they must deepen their understanding of water sources. That knowledge can help them assess how plants and animals function in current and possible future climates.

Various theories of religion hypothesize a connection between death anxiety and religiosity. In particular, Terror Management Theory’s worldview defence hypothesis predicts that death anxiety is lowest among very religious and irreligious individuals, and highest among uncertain individuals. Likewise, the supposition that death anxiety motivates religious belief, which in turn mitigates death anxiety, predicts that religiosity increases with death anxiety among non-believers, and that death anxiety decreases as religiosity increases among believers. In both cases, a curvilinear relationship – specifically, an inverted-U curve – is predicted. We extracted 202 effect sizes from 100 studies for an “omnibus” religiosity meta-analysis, and six meta-analyses that examine particular dimensions of religiosity. We found high heterogeneity and a weak negative association between death anxiety and religiosity. A closer examination revealed that 10 of the 11 studies that directly tested for curvilinearity provided some support for an inverted-U pattern. The curvilinearity hypothesis cannot be ruled out, but more evidence – particularly on non-religious individuals, and in non-Western, non-Abrahamic contexts – is needed.
