Archives (PRELIMS & MAINS Focus) OLEANDER FLOWERS Syllabus Prelims – Science Context: Two Kerala government-controlled temple boards, which together manage 2,500-odd temples in the state, have banned use of oleander flowers (locally known as arali) in temple offerings after a 24-year old woman died after accidentally chewing some oleander leaves. Background:- Oleander’s toxicity has been recognised across the world. About Oleander Nerium oleander, commonly known as oleander or rosebay, is a plant cultivated worldwide in tropical, subtropical, and temperate regions. Known for its drought tolerance, the shrub is often used for ornamental and landscaping purposes. In Kerala, the plant is known by the names of arali and kanaveeram and is grown along highways and beaches as a natural, green fencing. There are different varieties of oleander, each with a flower of a different colour References in Ayurveda : The Ayurvedic Pharmacopoeia of India (API), a government document that describes the quality, purity, and strength of drugs used in Ayurveda, mentions oleander. According to API, an oil prepared from the root bark can be used to treat skin diseases. Charka [Charak Samhita] has prescribed the leaves of white-flowered variety externally in chronic and obstinate skin diseases of serious nature including leprosy. Bhavaprakasha has described Karvira [another name of the plant] as a visha (poison) and indicated it in treatment of vrana (infected wounds), kustha (skin diseases including leprosy), krimi (microbes and parasites), kandu (itching) etc Ingestion or inhalation of smoke from burning oleander can be intoxicating. This is due to the properties of cardiac glycosides (a type of chemical) including oleandrin, folinerin, and digitoxigenin, which are present in all parts of the plant. Cardiac glycosides are steroidal compounds capable of exerting pharmacological effects on cardiac muscle. The primary therapeutic value of these glycosides lies in their ability to exert profound tonic effects on the heart [stronger and faster heart contractions]. Effects of oleander toxicity include nausea, diarrhea, vomiting, rashes, confusion, dizziness, irregular heartbeat, slow heartbeat, and, in extreme cases, death.

Background: The security vulnerability was being exploited in the wild, and could result in data leakage, code execution and crashes in the software.This is the fifth zero-day exploit Google fixed since the start of this year. Three zero-day exploits were discovered in March 2024. Key Takeaways A Zero-Day Vulnerability is an undiscovered flaw in an application or operating system. The term “Zero day” refers to the fact that the software or device vendor has zero days to fix the flaw because malicious actors can already use it to access vulnerable systems. The unknown or unaddressed vulnerability is referred to as a zero-day vulnerability or zero-day threat. A Zero-Day Exploit is a cyberattack vector that takes advantage of this unknown or unaddressed security flaw. A zero-day attack is when a malicious actor uses a zero-day exploit to plant malware, steal data, or otherwise cause damage to users, organizations, or systems. Zero-day vulnerabilities—especially in widely-used operating systems or computing devices—are a severe security risk. They leave huge numbers of users or entire organizations wide open to cybercrime until the vendor or the cybersecurity community identifies the problem and releases a solution. A similar but separate concept, Zero-Day Malware, is a virus or malware for which the signature is unknown or as yet unavailable, and therefore undetectable by many antivirus software solutions or other signature-based threat detection technologies Source: Hindu Kaziranga National Park Syllabus Prelims – Environment Context: Assam’s Kaziranga National Park collects highest revenue in its 50-year history.The revenue collected by the authorities of Kaziranga National Park, from the tourists, touches ₹8.8 crore. Background: Kaziranga National park is sprinkled with elephant-grass meadows, swampy lagoons, and dense forests is home to more than 2200 Indian one-horned rhinoceros, approximately 2/3rd of their total world population. About Kaziranga National Park: Kaziranga National Park is a national park located in the Golaghat and Nagaon districts of the state of Assam, India. Located on the edge of the Eastern Himalaya biodiversity hotspot, the park combines high species diversity and visibility. The park is a UNESCO World Heritage Site. It’s renowned for its population of the Indian one-horned rhinoceros, which is one of the main attractions for visitors. Kaziranga is also recognized as an Important Bird Area by BirdLife International for the conservation of avifaunal species. The park’s contribution in saving the Indian one-horned rhinoceros from the brink of extinction at the turn of the 20th century to harbouring the single largest population of this species is a spectacular conservation achievement. The park is spread over an area of 1,090 km² (420 sq mi) and is home to a large breeding population of elephants, wild water buffalo, and swamp deer. The Endangered Ganges dolphin is also found in some of the closed oxbow lakes. Over the time, the tiger population has also increased in Kaziranga, and that’s the reason why Kaziranga was declared as Tiger Reserve in 2006. Due to the difference in altitude between the eastern and western areas of the park, one can see mainly four types of vegetation like alluvial inundated grasslands, alluvial savanna woodlands, tropical moist mixed deciduous forests, and tropical semi-evergreen forests. Kumbhi, Indian gooseberry, the cotton tree, and elephant Apple are amongst the famous trees that can be seen in the park. It is criss-crossed by four major rivers, including the Brahmaputra. The park faces several challenges, including poaching, habitat loss due to human encroachment, and annual flooding from the Brahmaputra River. Efforts to mitigate these threats involve anti-poaching measures, community involvement, and habitat restoration projects.
