Scientists at the Copernicus Climate Change Service (C3S) reported 2024 as the hottest year since global temperature tracking began in 1850. Copernicus Climate Change Service (C3S) is part of the European Union’s (EU) Copernicus Earth Observation Programme and is managed by the European Centre for Medium-Range Weather Forecasts (ECMWF). It provides free access to climate data on past, present, and future climates globally. C3S’s Climate Data Store offers updated datasets, tools, and expert guidance for visualizing climate information. The service supports a wide range of users, including scientists, policymakers, and the public.

Notes:
The Sri Lankan Navy recently arrested 17 Indian fishermen near Neduntheevu Island. Neduntheevu, also called Delft Island, is the largest island in the Palk Strait, Sri Lanka. It covers 50 sq.km, with an 8 km length and 6 km width. The island is flat, oval-shaped, and often wind-swept, offering a soothing environment. It lacks streams; freshwater comes from surface water and artificial ponds. The island has dry shrubs, semi-arid tropical plants, and tall palm trees. A Dutch fort made of coral chunks is located on the island, which has a population of 4,800.

Notes:
Five Maoists, including two women, were killed in an encounter with security forces in Indravati National Park, Bijapur, Chhattisgarh. Indravati National Park is located in Bijapur district, Chhattisgarh. It was established in 1981. It became a tiger reserve in 1983 under India’s Project Tiger. The park is named after the Indravati River, which flows east to west and forms its northern boundary with Maharashtra.

Notes:
A rare carnivorous plant, Utricularia, has been found in large numbers at Rajasthan’s Keoladeo National Park. Utricularia, or bladderwort, belongs to the family Lentibulariaceae and includes 220 species found in temperate and tropical habitats worldwide. These plants lack roots and have floating stems with simple or divided leaves. They produce small carnivorous bladders that range from dark to transparent and trap tiny animals like insect larvae and water fleas. The trap door mechanism activates within milliseconds, capturing prey efficiently. Utricularia plants are found in lakes, streams, and waterlogged soils, with some species being invasive.

Notes:
The Gangasagar Mela organizers introduced initiatives like certificates for pilgrims, e-Anushandhan for facilities access, and e-Parichay QR code identity bands. The Gangasagar Mela is an annual Hindu festival held on Sagar Island, West Bengal, at the confluence of the Ganges and the Bay of Bengal. It includes rituals like the sacred bath and Deepdan and is celebrated during Makar Sankranti, marking the Sun’s transition into Capricorn.

Notes:
Uttar Pradesh Transport Department proposed a “No Helmet, No Fuel” policy to reduce road accidents involving two-wheelers. The policy will begin in Noida on January 26, 2025, aiming to enforce helmet use and improve road safety. Fuel stations statewide must display “No Helmet, No Fuel” signs and deny fuel to riders and pillions without helmets. The policy was introduced in Gautam Buddh Nagar in 2019 but was inconsistently implemented. Awareness campaigns and education for fuel station operators on the Motor Vehicles Act, 1988, and related rules are being prioritized.

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.
