Current Affairs Quiz - January, 2025

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:
The Kumani Bank mud volcano erupted in 2023, creating a temporary “Ghost Island.” Kumani Bank mud volcano is located 25 km off Azerbaijan’s eastern coast in the Caspian Sea. The island, about 400 meters across, formed in 2023 and eroded back into the sea by late 2024. Ghost Islands are temporary land masses created by volcanic activity that disappear over time. The island provides geological insights into tectonic processes and subsurface pressure dynamics. It offers clues about similar features on Mars for planetary exploration. The area is linked to methane and gas emissions and highlights Azerbaijan’s unique geological landscape with over 300 mud volcanoes.

Notes:
Australian scientists discovered a larger, more venomous Sydney funnel-web spider species, named Atrax christenseni. The new species, called “Big Boy,” is 9 cm (3.54 inches) long and was first found in the early 2000s near Newcastle. It is dark brown to black with finger-like spinnerets at the abdomen’s end. Its venom glands are bigger, and its fangs are longer. Only male funnel-web spiders cause human deaths due to their stronger venom. Found in bushy suburban areas, forests, and shady gullies. Funnel-web spiders are among the most dangerous, with venom containing 40 toxic proteins.

Notes:
The Musi River Historic Buildings in Hyderabad and Bhuj Historic Water Systems in Gujarat are listed in the 2025 World Monuments Watch by the New York-based World Monuments Fund (WMF). These sites face risks from climate change and water crises, highlighting the need for advocacy and preservation. WMF emphasizes heritage as a pathway for rejuvenation, sustainability, and resilience amid Hyderabad’s environmental challenges and rapid change.

Notes:
The “One Plate, One Bag” campaign was launched at the Maha Kumbh, Prayagraj, to promote a plastic-free event. Cloth bags and steel plates and glasses are being distributed to replace plastic and disposable items. Around 70,000 cloth bags have been distributed from six centers so far. More than 2 million steel plates and glasses collected nationwide are being supplied to langars and food outlets. Uttar Pradesh CM Yogi Adityanath urged pilgrims to adopt eco-friendly practices and avoid single-use plastic during the pilgrimage.

Notes:
International Labour Organisation (ILO) has released the World Employment and Social Outlook Report for 2025. The report highlights ongoing global labor market struggles due to geopolitical tensions, climate change costs, and unresolved debt issues. The global jobs gap in 2024 was 402 million, including 186 million unemployed, 137 million temporarily unavailable, and 79 million discouraged workers. The global unemployment rate stood at 5%, with youth unemployment at 12.6%. Low-income countries face challenges creating decent jobs, with informal work returning to pre-pandemic levels. Labour force participation declined in low-income nations but increased among older workers and women in high-income countries, though gender gaps persist.

Notes:
Satellite images show a nearly completed airstrip on Yemen’s Abd al-Kuri Island, likely built by the UAE. Abd al-Kuri Island is 65 miles southwest of Socotra, in the Indian Ocean, part of the Socotra Archipelago. Although it belongs to Yemen, the island is geographically closer to Somalia, about 110 km northeast of Cape Gwardafuy. The island is rocky, 35 km long, and 5 km wide, with its highest point at 700 meters, Mount Jebel Saleh. With fewer than 500 residents, its inhabitants mainly rely on fishing, and settlements are connected by dirt roads. The island features the endemic Euphorbia abdalkuri plant.

Notes:
INS Mumbai, an indigenously built guided missile destroyer, is participating in the fourth edition of Exercise LA PEROUSE. The exercise involves navies from Australia, France, the UK, the US, Indonesia, Malaysia, Singapore, and Canada. It focuses on enhancing maritime situational awareness, surveillance, interdiction, air operations, and information sharing. The exercise highlights India’s naval synergy, interoperability, and commitment to a rules-based maritime order. It aligns with India’s SAGAR vision to ensure security and growth in the Indo-Pacific region.

Notes:
The Indian men’s and women’s teams won the inaugural Kho Kho World Cup 2025 titles at the Indira Gandhi Indoor Stadium in New Delhi. The men’s team defeated Nepal 54-36, while the women’s team beat Nepal 78-40 in their respective finals. The tournament, backed by the Indian Olympic Association (IOA), featured 20 men’s and 19 women’s teams. Both finals showcased India’s dominance, with strong attacking and defensive performances.

Notes:
Lake Naivasha in Kenya is severely affected by the invasive water hyacinth, covering large areas. It is a shallow freshwater lake in Kenya’s southern Rift Valley, fed by the Malewa and Gilgil Rivers from the Aberdare Mountains. The lake is surrounded by extinct or dormant volcanoes and features vegetation like Cyperus papyrus and submerged plants. It supports waterbirds, large mammals, fishing, flower farming, and geothermal power, making it economically vital. Lake Naivasha is a Ramsar site, recognized for its ecological importance. Water hyacinth, an invasive species from South America, blocks sunlight, reduces airflow, and harms aquatic life.
