Investment in sanitation and drinking water infrastructure is essential for universal access to these services in developing countries. Universal coverage of water and sanitation services (WSS) can prevent the dissemination of waterborne diseases and mitigate their adverse effects. These diseases are respons...
This year marks the mid-point for the implementation of the United Nations 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals, including Sustainable Development Goal 14 (‘Life below water’). We asked a range of researchers working across marine science, conservation, ...
Mushroom growing is a bit like a science project, and there’s an element of trial and error involved. However, there are steps that you can take to avoid costly mistakes. One of the biggest mistakes that mushroom growers make is not ensuring that their substrate is at the right temperature...
The aim of this study was to assess the potential usefulness of two low-cost adsorbents, namely aluminum drinking water treatment residual (Al-WTR) and crushed concrete (CC), as filter media intended to remove P from DW and forestry runoff. These wastewaters are representative sources of point...
except for once a day when the tubes were opened to remove pupal social fluid. Pulled glass capillaries were prepared as described elsewhere29, and used to remove and/or collect secretion droplets. We were careful to leave no remains of the secretion behind on the pupae or the inside of the...
economic and cultural schisms promoted by our rulers.It’snot capitalism vs. socialism, although a sacred-Earth society would probably look more like the latter than the former.It’s notscience vs. religion; it’s an understanding that unites them in service to creation. We are all children ...
treatment options: 1) the initial decision to adopt/purchase a POU device; 2) the installation of the device/physical alteration of the household environment; 3) the recurrent decisions to use the filtered water for domestic uses, including drinking and cooking, over other sources such as ...
Science for society Water is a vital resource and is critical for sustainable development. Human survival, energy and food production, and healthy ecosystems are all dependent on water availability. Water security is also impacted by and is at the core of adaptation to climate change. Yet, pressu...
