The action followed inputs from United States (US) authorities and led to the arrest of two individuals from Mangalore and Delhi.The CBI’s International Operations Division registered cases under the Indian Penal Code (IPC), Information Technology (IT) Act, 2000, and Protection of Children from Sexual Offences (POCSO) Act, 2012.This comes as part of CBI’s broader efforts under earlier operations like Operation CARBON (2021) and Operation Megh Chakra (2022)

Notes:
The European Red Admiral butterfly, scientifically called Vanessa atalanta, has been recorded for the first time in India near Dharamshala, Himachal Pradesh. This rare sighting was confirmed during a butterfly survey at Thatharna Hill in the Dhauladhar mountain range, at an altitude of 2,500 metres. The observation was verified by Himalayan butterfly expert Lovish Garlani from the Himachal Pradesh Forest Department. This raises the total number of butterfly species in Himachal Pradesh to 440, highlighting the region’s rich biodiversity. The species is known for long migrations across Europe and North America and was last seen in South Asia in 2022 in Pakistan after a 93-year gap. It has no confirmed records from China, Mongolia, or Afghanistan, making its presence in India a significant eastward range expansion.

Notes:
A recent report by the Wildlife Justice Commission (WJC) says global trafficking of pangolin scales has dropped sharply since 2020 due to COVID-19 disruptions, strong law enforcement, and changing smuggling methods. Pangolins are insect-eating mammals found in tropical forests, grasslands, and farms, often near people. There are 8 species of pangolins — 4 in Africa and 4 in Asia, including the Indian pangolin found in India, Nepal, Sri Lanka, and Bangladesh. They eat ants and termites, helping control pests and improve soil, which supports healthy ecosystems. Pangolins are hunted for their meat and scales used in traditional medicine. The Indian pangolin is listed as Endangered and the Chinese pangolin as Critically Endangered on the International Union for Conservation of Nature (IUCN) Red List.

Notes:
On May 2, 2025, Australian boatbuilder Incat launched the world’s largest electric-powered ship, named Hull 096. The ship is a 130-metre-long aluminium catamaran designed for South American ferry operator Buquebus. It can carry 2,100 passengers and up to 225 vehicles across the River Plate between Buenos Aires and Uruguay. Hull 096 is powered by over 250 tonnes of batteries with an Energy Storage System (ESS) providing more than 40 megawatt hours of capacity. It was initially planned to run on Liquefied Natural Gas (LNG) but was later converted to battery power. The launch highlights a major step towards reducing maritime carbon emissions, which account for about three percent of global greenhouse gas emissions. This comes after the International Maritime Organization (IMO) voted for a global carbon pricing system, with cleaner fuels required by 2028.

Notes:
The Pulitzer Prizes 2025 were recently announced by the Pulitzer Prize Board to honor excellence in journalism and the arts. The Pulitzer Prize is considered the most prestigious award in journalism in the United States. It was established in the year 1917 and is administered by Columbia University. The award is overseen by the Pulitzer Prize Board, which consists of judges appointed by Columbia University. The prize is named after Joseph Pulitzer, a famous newspaper publisher who left funds in his will to create the School of Journalism and the Pulitzer Prize.

Notes:
Defence Research and Development Organisation (DRDO) and Indian Navy successfully carried out combat firing of the Multi-Influence Ground Mine (MIGM) with reduced explosives. MIGM is an advanced underwater naval mine developed by Naval Science and Technological Laboratory, Visakhapatnam, with support from other DRDO labs. It is designed to target stealth ships and submarines, enhancing the Indian Navy’s underwater combat strength. The mine has intelligent systems with ARM processor-based electronics that process sensor data in real time for precise defence action. Bharat Dynamics Limited and Apollo Microsystems Limited are the production partners. The system will strengthen India’s coastal defence and underwater deterrence.

Notes:
On May 8, 2025, twenty-two Naxalites were killed in an encounter during Operation Sankalp in the forests of Bijapur district, Chhattisgarh. Operation Sankalp is a large-scale counter-insurgency drive launched on April 21, 2025, targeting Maoist strongholds across 800 sq km near the Chhattisgarh-Telangana border. The operation involves nearly 28,000 personnel from District Reserve Guard (DRG), Bastar Fighters, Special Task Force (STF), Central Reserve Police Force (CRPF), and Commando Battalion for Resolute Action (CoBRA).

Notes:
World Red Cross Day is observed every year on May 8 to honour the birth anniversary of Jean Henry Dunant, the founder of the Red Cross, who was born 197 years ago. The theme for this year is “Keeping Humanity Alive,” which celebrates people who dedicate their time and lives to reduce others’ suffering and protect human dignity.

Notes:
Researchers from the Monterey Bay Aquarium Research Institute (MBARI) and Florida State University have created a new method to estimate how much carbon is transported from the ocean surface to deeper waters. This method uses satellite data and is called the Lagrangian Growth-Advection Model. It helps map how phytoplankton develop and how carbon is transported in the ocean by following surface currents, especially in nutrient-rich upwelling zones like the California Current. This model improves our understanding of ocean carbon cycles by showing how ocean movement and biological processes interact over time and space. It supports climate research by offering a more accurate way to estimate oceanic carbon export using satellite data.

Notes:
India has launched chip-based e-passports as part of its digital transformation of travel documentation. These passports, embedded with Radio Frequency Identification (RFID) chips and biometric data, aim to improve security, efficiency, and convenience for international travelers. The initiative, under the Passport Seva Programme Version 2.0, began on April 1, 2024. The new passports make India comparable to countries like the USA, UK, and Germany in using advanced e-passport technology. Features include enhanced security, RFID chips, scannable barcodes, and a tamper-proof design. The goal is to improve passport security, streamline immigration, and support India’s digital transformation.
