Nearly 600 years ago, a massive volcanic eruption sent clouds of sulfurous gas and ash high into the atmosphere. The blast known as the 1458/59 CE event was so huge that it triggered decades of cooling, especially in the ...
Bivalves, such as clams, oysters and mussels, record seasonal environmental changes in their shells, making them living chronicles of climate history. A new study of bivalve shells has detected two major episodes of instability ...
More than 90% of plastic waste ends up in the soil, where it breaks down into microplastics that are invisible to the naked eye. Microplastic pollution of the soil poses a severe threat to soil health as it can harm essential ...
Plastic may well be a useful everyday item, but its careless disposal in oceans and inland waterways is a pressing global problem. Plastic pollution poses a significant threat to human health and the health of our planet. ...
Endotoxin, a toxic chemical found in bacteria, makes up only 0.0001% of PM2.5 fine particles but packs a serious punch when it comes to its bioactivity.
Powerful pulses of groundwater flow up from beneath Lakes Michigan and Huron, which together form one of the largest freshwater systems in the world. This groundwater flux may dramatically alter how and where ice forms, with ...
