Japan has restarted a reactor at the Kashiwazaki-Kariwa nuclear power plant, the world’s largest by capacity, nearly 15 years after the Fukushima disaster. Reactor No. 6, located northwest of Tokyo, was brought back online on Wednesday after a brief delay caused by an alarm issue. Commercial operations are expected to begin next month. The plant once had seven reactors with a total capacity of 8.2 gigawatts. Only one reactor is restarting for now, while others may remain offline or be decommissioned. Japan has been gradually reviving nuclear power to reduce energy imports and meet its clean energy targets by 2050. (PC: BBC)

Indian mountaineer Rohtash Khileri has reportedly become the first person to stay for 24 continuous hours on the summit of Mount Elbrus without using supplemental oxygen.

Canadian Prime Minister Mark Carney said the US-led global order has ended, speaking at the World Economic Forum in Davos. “We are in the midst of a rupture, not a transition. The old order is not coming back,” he said. Carney warned that major powers now use trade, finance and supply chains as tools of pressure. He said the idea of a fair rules-based system was “partially false” and applied unevenly. Carney said deep global integration has become a risk for many countries. He urged Canada to build domestic strength and diversify trade ties. He also called on middle powers to work together in a more divided world. (PC: India Today)

European Commission President Ursula von der Leyen announced the EU is "on the cusp" of signing a historic trade agreement with India, calling it the "mother of all deals" that would create a two-billion-person market representing nearly a quarter of global GDP.
