Current Affairs Quiz - January, 2025

Notes:
The Boda Tyohar festival, the largest annual celebration for the Hatti tribes in Himachal Pradesh, started recently with great enthusiasm. Hattis are a close-knit community known for selling home-grown crops, vegetables, meat, and wool at ‘haats’. They traditionally wear white headgear on ceremonial occasions. Hatti homeland spans the Himachal-Uttarakhand border, near the Giri and Tons rivers, tributaries of the Yamuna. There are two main Hatti clans, one in Trans-Giri, Himachal, and the other in Jaunsar Bawar, Uttarakhand.

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:
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:
The first astronomical observatory in Eastern India has been inaugurated in Garpanchkot Hills, Purulia, by the Satyendra Nath Bose National Centre for Basic Sciences (SNBNCBS). This is the sixth such observatory in India and is named after Satyendra Nath Bose. The observatory, located 600 meters above sea level at approximately 86° E longitude, fills a key gap in astronomical observations. It aims to aid scientific observations, student training, and foster national and international research collaborations. The observatory is strategically placed to observe transient astronomical phenomena. Satyendra Nath Bose Centre has partnered with Sidhu Kanu Birsa University for its operation.

Notes:
Researchers at the Guangzhou Institute of Geochemistry, China, developed Electrokinetic Mining (EKM) for eco-friendly extraction of rare earth elements (REEs). EKM uses an electric field to concentrate REEs, simplifying their separation. REEs are 17 metallic elements with critical properties for modern technologies, including magnetic, electronic, and chemical applications. EKM relies on electrokinetics, which involves the movement of particles or fluids under an electric field to extract REEs from ore.

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 Ministry of Electronics & Information Technology (MeitY) and Data Security Council of India (DSCI) launched the second edition of the Cyber Security Grand Challenge (CSGC 2.0). The prize pool has been increased to Rs. 6.85 crores from Rs. 3.2 crores. Innovators, startups, and entrepreneurs are invited to address six key cybersecurity challenges, including API Security, Data Security, and AI for Threat Detection. Intellectual property rights for solutions developed will stay with startups. The competition has four stages, with winners receiving Rs. 25 lakh, and the overall winner getting Rs. 1 crore. The initiative supports Digital India and Atmanirbhar Bharat.

Notes:
The Halda Festival is celebrated in January in Lahaul-Spiti, Himachal Pradesh. It honors Shiskar Apa, the Goddess of Wealth, to seek blessings for prosperity and a good harvest. Celebrations are most prominent in the Pattan, Gahar, and Chandra valleys.

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:
New research reveals that genetic mutations in Huntington’s Disease (HD) can have delayed effects, impacting disease progression over time. Huntington’s Disease (HD) is a genetic condition causing gradual loss of brain cell function, leading to their death. It affects brain regions regulating voluntary movement, memory, and decision-making, primarily the basal ganglia and brain cortex. HD is caused by a mutation in the HTT gene, which produces huntingtin protein crucial for neuron function. Mutated huntingtin proteins have abnormal shapes, damaging and killing neurons. HD is inherited; each child of an affected parent has a 50% chance of developing the disease. It affects 3 to 7 out of 100,000 people, primarily of European ancestry.
