China’s President Xi Jinping is expected to visit India for the BRICS meeting and may speak with Prime Minister Modi about improving relations.

Scientists say Mercury is becoming smaller as its hot interior slowly cools.

In India, women make up a very large share of informal workers in some districts, especially in the south and northeast.

Bihar flooded even though it had received less rain than usual because water came from upstream areas and the Ganga rose sharply.

A river’s backwater effect can make it harder for tributaries to drain into a swollen main river.

Manipur wants to use 1951 as a reference year for a possible citizens’ register.

Some groups support this, while others worry that old and incomplete records could wrongly exclude people.

“Normally, the rivers entering Bihar from Nepal — the Bagmati, Kamla, Kosi and Gandak — rise first, followed by the Ganga. This time, the Ganga became the main source of concern first.”
