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.

Notes:
Google-backed Pixxel launched India’s first private satellite constellation, marking a milestone for the country’s private space sector. The satellites use hyperspectral imaging technology to capture detailed data across light bands for agriculture, mining, environmental monitoring, and defense. This technology can help improve crop yields, track resources, monitor oil spills, and provide better details than existing technology. Three more satellites are expected to be deployed by mid-2025. The global satellite imagery market is projected to reach $19 billion by 2029.

Notes:
The Telecom Regulatory Authority of India (TRAI) recommended capping Internet tariffs for Wi-Fi service providers under the Prime Minister’s Wi-Fi Access Network Interface (PM-WANI) scheme at twice the rate of retail broadband. The PM-WANI scheme was launched in December 2020 by the Department of Telecommunication. The scheme aims to expand public Wi-Fi hotspots, especially in rural areas. It seeks to enhance digital infrastructure, increase employment for small entrepreneurs, and provide low-cost internet to underserved urban and rural households. The scheme encourages local shops to offer Wi-Fi for last-mile delivery without requiring a license or registration fee.

Notes:
The United Nations Children’s Fund (UNICEF) report “Prospects for Children in 2025” warns of escalating crises affecting children globally. More than 473 million children, or 19%, lived in conflict zones in 2023, facing risks like displacement, starvation, and trauma. Nearly 400 million children are in countries burdened by debt, limiting education, healthcare, and social services. In low-income nations, debt servicing outpaces social spending, deepening poverty for 1.8 billion children. Climate change impacts children, with only 2.4% of climate finance directed to child-responsive initiatives. Digital inequality affects access to essential services, especially for youth in low-income countries and adolescent girls. UNICEF calls for increased financing to protect children’s health, education, and well-being.

Notes:
The Department of Telecommunications (DoT) launched the Sanchar Saathi mobile app on January 17, 2025, to report fraudulent communications directly from call logs. The app builds on the Sanchar Saathi portal, launched in May 2023, aimed at combating fraud calls and improving mobile security.
