On 14 Nov, two studies published in the journal Cell found that the diversity of microscopic organisms habiting the Earth’s oceans are the least at the higher latitudes nearer to the poles and increase in a gradient towards the equator. The two studies analysed the diversity of these organisms in samples collected from ocean water ..

Plastic pieces that are less than 5mm in length are called microplastics. Microplastics can be formed by fragmentation of large plastic waste material. Microfibres from washing of textiles, microbeads used in cosmetics and even paint from land run-offs can dump microplastics in the ocean. Biomagnification refers to increasing concentration of a substance, such as a toxic ..
