Notes:
IIT Roorkee researchers developed a method to degrade plasticizers like diethyl hexyl phthalate (DEHP) using bacterial enzymes. DEHP is found in plastics and personal care products, posing health risks. Esterase enzyme from Sulfobacillus acidophilus breaks DEHP into mono-(2-ethylhexyl) phthalate (MEHP) and 2-ethyl hexanol. The enzyme was structurally studied using X-ray crystallography and remains active for about a month. Researchers used four additional enzymes from Comamonas testosteroni to complete the degradation process. Integrating enzymes into bacteria ensures prolonged activity and continuous degradation without needing fresh batches. Plasticizers enhance flexibility and shine in products but can be absorbed through the skin, posing health dangers.

Centre for Development of Telematics (C-DOT) and IIT Delhi signed an agreement to develop THz communication front ends for 6G under the Telecom Technology Development Fund (TTDF). TTDF is established under the Universal Services Obligation Fund (USOF), now called Digital Bharat Nidhi, by the Department of Telecom. The fund supports research, design, prototyping, testing, and manufacturing in telecommunications. It aims to foster rural-specific communication technologies, promote technology ownership, and encourage indigenous manufacturing. TTDF seeks to boost exports, reduce imports, enhance co-innovation, and support Intellectual Property creation in the telecom sector.

Notes:
The online ‘central suspect registry’ has prevented six lakh fraudulent transactions, saving ₹1,800 crore. It strengthens fraud risk management with a registry of cybercriminal identifiers. It was created using the National Cybercrime Reporting Portal (NCRP). It includes data on 1.4 million cybercriminals. It hs been developed by the Indian Cyber Crime Coordination Centre (I4C) with input from banks and financial institutions. Indian Cyber Crime Coordination Centre (I4C) , under the Ministry of Home Affairs, coordinates efforts against cybercrime. It also prevents cyberspace misuse by extremist and terrorist groups.
