Notes:
IIT Bombay researchers developed a solution to tackle soil pollution using bacteria that consume toxic pollutants and produce essential nutrients. These bacteria degrade harmful substances, boost plant growth hormones, inhibit harmful fungi, and improve nutrient availability for plants. This innovation can reduce reliance on chemical pesticides and enhance soil health and fertility. The bacteria, mainly from the genera Pseudomonas and Acinetobacter, were isolated from highly toxic environments and contaminated soils. They effectively break down aromatic pollutants like carbaryl, naphthalene, and phthalates, commonly found in pesticides and industrial by-products. The research offers an eco-friendly alternative to expensive traditional soil remediation methods.

Notes:
Researchers from IIT Guwahati and Bose Institute, Kolkata, created an advanced injectable hydrogel for localized cancer treatment. The hydrogel acts as a stable reservoir, releasing anti-cancer drugs in a controlled way. It minimizes harm to healthy cells while targeting cancer effectively. The breakthrough is expected to revolutionize breast cancer therapy. The hydrogel is made from protein-based ultra-short peptides, stable at injection sites, and insoluble in body fluids. The peptides are biocompatible and biodegradable, ensuring safety and effectiveness.

Notes:
Tularemia, also called ‘rabbit fever,’ has risen by over 50% in the US recently. It is a rare but potentially deadly infectious disease. It primarily affects children aged 5-9, older men, and American Indians or Alaska Natives. Tularemia is caused by the bacterium Francisella tularensis, which can infect various animals, especially rabbits and rodents. The disease is transmitted to humans through tick bites, contact with infected animals, or contaminated water. Symptoms can range from skin ulcers to severe respiratory issues.

Notes:
A male tiger, T-2402, left Sariska Tiger Reserve and injured three people. Sariska Tiger Reserve is located in Rajasthan, covering 800 sq km in the Aravali Hills. It was a hunting ground for the Maharaja of Alwar before becoming a reserve in 1955 and a national park in 1979. It was the first reserve globally to successfully relocate tigers. The area is known for temples, palaces, and lakes like Pandu Pol, Bhangarh Fort, Siliserh Lake, and JaiSamand Lake.

Notes:
Amit Shah chaired the 7th Island Development Agency (IDA) meeting in New Delhi, reviewing development initiatives in the Andaman and Nicobar Islands and Lakshadweep. The focus was on achieving 100% renewable energy generation through solar panels and windmills. The ‘PM Surya Ghar’ scheme will install solar panels in all households across both island groups. The Union Government established the Island Development Agency (IDA) on June 1, 2017. The agency focuses on the development of islands.

Notes:
CSIR-Central Institute of Mining and Fuel Research (CSIR-CIMFR) successfully conducted India’s first trial blast using the Dozer Push Mining Method, integrating digital technologies for enhanced safety and efficiency. The trial took place at Parsa East and Kanta Basan (PEKB) Coal Mine, Chhattisgarh, operated by Adani Enterprises. The method aims to optimize mining processes while controlling vibrations and flyrock. It uses automated machinery, including unmanned drill machines and large-sized dozers. The method is a cost-effective alternative to traditional mining techniques like truck-shovel and dragline methods.

Notes:
Major Wall Street banks have exited the Net-Zero Banking Alliance, a prominent group in global finance. The Alliance, led by banks and convened by the UN, commits members to align lending, investments, and capital activities with net-zero greenhouse gas emissions by 2050. The United Nations Environment Programme Finance Initiative (UNEP FI) convenes the Net-Zero Banking Alliance (NZBA). It is governed by a Steering Group, including member banks, UNEP FI Secretariat, and the UN. Banks in the alliance commit to transitioning GHG emissions in their portfolios and setting 2030 and 2050 targets with updates every five years. Members must annually publish emissions data. No Indian bank is currently part of this alliance.

Notes:
Tamil Nadu Chief Minister M.K. Stalin announced a $1 million prize for deciphering the ancient Indus Valley script. The announcement was made during the centenary celebration of the Indus Valley Civilization at an international conference in Chennai. The Chief Minister emphasized the importance of decoding the script to understand ancient history. Tamil Nadu is supporting archaeological research through initiatives like a dedicated research chair named after Iravatham Mahadevan. This move reflects the state’s commitment to promoting historical and archaeological studies.

Notes:
India and the U.S. agreed to co-produce sonobuoys for the Indian Navy’s Undersea Domain Awareness (UDA). Sonobuoys are electro-mechanical acoustic sensors used to detect submarines and ships underwater. They are dropped by naval helicopters or aircraft, deploy automatically upon hitting water, and use inflatable systems for surface communication. Sensors descend to a specific depth to relay underwater acoustic data. Sonobuoys can be used in active or passive modes for tracking. Deploying multiple sonobuoys in a pattern allows precise location tracking of submarines, enhancing naval capabilities.

Notes:
The Flamingo Festival 2025 returns to Andhra Pradesh after a four-year break, celebrating migratory birds, especially flamingos, at Pulicat Lake and Nelapattu Bird Sanctuary. The event covers five key locations: Nelapattu Bird Sanctuary, Atakanithippa, BV Palem (Pulicat Lake), Sullurpet’s Government Junior College, and Sri City. More than 200 bird species, including flamingos, grey pelicans, and open-bill storks, are expected to migrate to the region. Activities include birdwatching, eco-friendly biodiversity sessions, boating, cultural programs, and stalls at Sullurpeta.
