Cambridge researchers are set to explore the uncharted depths of life in the extreme cold, with findings that could reshape our understanding of biology and pave the way for future scientific breakthroughs.
Paraguayan import/export operations, which are heavily dependent on barge transport through the Paraná and Paraguay Rivers, saw costs go up 29.2% interannually in July as lower water levels limited both navigation and the amount of cargo each vessel can carry.
