The impacts of climate change on coastal areas are severe than inland as they are vulnerable to flooding and extreme weather phenomena like cyclones, tornadoes etc. As the climate crisis deepens, a quarter of India's population, who live along the coasts, have another issue to worry about – availability of freshwater. Due to unchecked pumping of groundwater for daily use and rainfall variation, freshwater sources are being depleted. Besides, saltwater from the sea is unwittingly finding its way into local aquifers through a process called seawater intrusion. Although many independent studies, conducted at different locations, have observed depletion in freshwater sources along India's coasts, there is no comprehensive study yet. Now, researchers at Anna University, Chennai, have tried to address the extent of seawater intrusion in the Indian coastal regions in a study published in journal Environmental Science and Pollution Research. The study was funded by the National Centre for Earth Sciences Studies, Earth System Science Organisation, and the Ministry of Earth Sciences.

Researchers have uncovered a previously unknown species of the unique aquatic insect known as the water-penny beetle, marking the first-ever record of its genus in Tamil Nadu. The discovery, made in the fast-flowing Kurangani stream of the Bodi hills, introduces Jaechanax kuranganiensis to the world.
