Microplastic debris floating at the ocean surface can harm marine life. Understanding the severity of this harm requires knowledge of plastic abundance and distributions. Dozens of expeditions measuring microplastics have been carried out since the 1970s, but they ha...ve primarily focused on the North Atlantic and North Pacific accumulation zones, with much sparser coverage elsewhere. Here, we use the largest dataset of microplastic measurements assembled to date to assess the confidence we can have in global estimates of microplastic abundance and mass. We use a rigorous statistical framework to standardize a global dataset of plastic marine debris measured using surface-trawling plankton nets and coupled this with three different ocean circulation models to spatially interpolate the observations. Our estimates show that the accumulated number of microplastic particles in 2014 ranges from 15 to 51 trillion particles, weighing between 93 and 236 thousand metric tons, which is only approximately 1% of global plastic waste estimated to enter the ocean in the year 2010. These estimates are larger than previous global estimates, but vary widely because the scarcity of data in most of the world ocean, differences in model formulations, and fundamental knowledge gaps in the sources, transformations and fates of microplastics in the ocean.

Consolidating Earthquake Safety Assessment Efforts in India. This document provides succinct instructions on how to perform rapid visual screening (RVS), a quick method of earthquake assessment of buildings. It covers a brief description of RVS and its role as a simplified qualitative assessment in ...the wider methodology of earthquake assessment of buildings, and the recommended forms for pre-earthquake and post-earthquake Level 1 Assessments for seven building typologies. The method recommended by the primer is the BMTPC method which provides both Seismic Safety Index and Performance Rating to a particular building.

Onchocerciasis used to be an important public health problem in Africa, with over 37 million people infected and millions suffering from debilitating skin disease, terrible itching, impaired vision and
blindness. But the epidemiological situation has improved dramatically over the last two decades.... Community directed treatment with ivermectin has effectively brought the disease under control in most endemic areas where onchocerciasis is no longer a public health risk.
