The Gauhati High Court has observed that the constitutional dispute between the Union government and the Government of Nagaland over petroleum and natural gas regulations in the state falls under the exclusive jurisdiction of the Supreme Court of India. In a judgment delivered on March 10, a division bench comprising Justice Kalyan Rai Surana and Justice Manish Choudhury made the observation while disposing of a suo motu public interest litigation (PIL) related to the validity of the Nagaland Petroleum and Natural Gas Regulations, 2012 and the Nagaland Petroleum and Natural Gas Rules, 2012.

Researchers at the Indian Institute of Technology Guwahati have created a new radiation-resistant cement mortar aimed at enhancing safety in nuclear facilities by improving the structural integrity and radiation-shielding capabilities of concrete. This innovation incorporates microparticles—boron oxide, lead oxide, bismuth oxide, and tungsten oxide—into conventional cement mortar, enhancing its density, durability, and ability to block harmful radiation. The enhanced mortar significantly reduces radiation penetration, thereby mitigating the risk of leaks in sensitive environments like nuclear reactors. The study revealed that each microparticle affects the mortar differently: lead oxide increases density and strength, tungsten oxide improves cracking resistance and durability, while…
