DAILY DOSE 8th JUNE -2024 CURRENT AFFAIRS
1) Blaze Star : Celestial Event
- The upcoming explosion of “Blaze Star” (T Coronae Borealis), a rare celestial event, will be visible to the naked eye for the first time since 1946. This event highlights the dynamic nature of the universe and the complex processes governing stellar evolution.
- Blaze Star is officially known as T Coronae Borealis (T CrB), is a dim star located 3,000 light-years away from our solar system.
- It is found in the constellation Corona Borealis (the “Northern Crown”).
- The Blaze Star is a rare example of a recurrent nova, occurring once in every 80 years.
- Stellar components: The nova involves a binary star system comprising a white dwarf and a red giant.
2) Parengyodontium album : Marine Fungus
- A marine fungus called Parengyodontium album has been discovered to break down plastic polyethene (PE) in the ocean.
- Parengyodontium album is a marine fungus that can break down plastic polyethene (PE), the most common plastic in the ocean.
- It was discovered by Marine microbiologists from the Royal Netherlands Institute for Sea Research (NIOZ).
- In this bioremediation process, the PE-derived carbon is converted into the fungal biomass of album, serving as its energy source.
3) World Summit On The Information Society:
- India played a significant role in the ITU’s WSIS+20 Forum High-Level Event and the ‘AI for Good’ Global Summit. During these events, India showcased its leadership in drafting global standards for responsible and trustworthy AI.
- The WSIS+20 Forum commemorates 20 years of progress since the World Summit on the Information Society (WSIS), which occurred in Geneva in 2003 and Tunis in 2005.
- This annual forum, co-organized by ITU, UNESCO, UNDP, and UNCTAD, aims to create a multi-stakeholder platform addressing issues raised by information and communication technologies inclusively at national, regional, and international levels.
- Its goal is to foster a people-centric, inclusive, and development-oriented Information Society, enabling universal access, utilization, and sharing of information.
4) Preston Curve : Study
- The Preston curve refers to the empirical relationship between life expectancy and per capita income in a country, proposed by American sociologist Samuel H. Preston in 1975.
- The curve shows that people in richer countries generally have longer life spans compared to those in poorer countries, likely due to better access to healthcare, education, nutrition, etc.
- As a poor country’s per capita income rises, its life expectancy increases significantly initially.
- For example, India’s per capita income rose from Rs 9,000 in 1947 to
5) Breeding And Nurturing Of Striped Hyenas And Asiatic Wild Dogs : Indira Gandhi Zoological Park
- The Indira Gandhi Zoological Park (IGZP) in Visakhapatnam has been at the forefront of wildlife conservation in India, particularly in the successful breeding and nurturing of Striped hyenas and Asiatic wild dogs (Dhole).
- Indira Gandhi Zoological Park (IGZP) is an ex-situ facility established in 1977, located amidst Seethakonda Reserve Forest in the Visakhapatnam district of Andhra Pradesh.
- It is surrounded by Eastern Ghats on three sides and the Bay of Bengal on the fourth side.
- It is a large category zoo recognised by the Central Zoo Authority.
6) Wheat Imports : After 6 Years Gap
- India, the world’s second-largest wheat producer, plans to begin wheat imports after a six-year gap to replenish depleted reserves and control rising prices, driven by three consecutive years of disappointing crops.
- New Delhi is expected to abandon a 40% tax on wheat imports this year paving the way for private traders and flour millers to buy from producers such as top exporter Russia, albeit in modest volumes.
- India’s wheat production has declined in the last 3 years due to unfavourable weather conditions, leading to a sharp drop in wheat output.
- The government estimates this year’s wheat crop to be 6.25% lower than the previous year’s (2023) record production of 112 million metric tons.
- As of April 2024, wheat stocks in government warehouses have dropped to 7.5 million tons, the lowest in 16 years, due to the government selling over 10 million tons from its reserves to control domestic prices.
7) Direct Seeded Rice:
- ICAR has commercialised herbicide-tolerant (Ht) basmati rice varieties that can control weeds
- Direct Seeded Rice (DSR) is a modern rice cultivation technique where rice seeds are directly sown into the field, replacing the traditional method of transplanting seedlings from a nursery.
- It is an efficient, and sustainable method of rice cultivation that offers significant benefits for farmers, the environment, and the economy.
- ICAR commercialised non-genetically modified (non-GM) Ht basmati rice. These varieties allow direct application of the herbicide Imazethapyr due to a mutated ALS gene.
8) Spot Bellied Eagle Owl:
- Pench Tiger Reserve (PTR), Maharashtra, recently reported the first photographic record of a spot-bellied eagle owl.
- Spot Bellied Eagle Owl is also known as the forest eagle-owl, is a large bird of prey with a formidable appearance.
- Scientific Name: Ketupa nipalensis
- It can be found in a variety of habitats, including tropical and subtropical forests, woodlands and savannas.
- It is commonly found in India, Sri Lanka, Nepal, Bhutan, Bangladesh and parts of Southeast Asia.
- It is a large species of owl. It measures about 50 to 65 cm in length and weighs 1500 to 1700 grams.
- Its wingspan can reach up to 1.7 meters.
9) Lost Nile Branch Key To Pyramid Construction:
- A study discovered an ancient Nile river branch that helped transport workers and materials to Egypt’s pyramids, now buried under modern landscapes.
- Researchers employed technologies including satellite imagery, high-resolution digital elevation data, and historical maps to trace the path of the now-vanished Ahramat Branch of Nile River.
- Key Highlights of the Study:
- The revelation of the Ahramat Branch, a previously unknown Nile channel from Lisht (village) to Giza (city), illuminates its crucial role in transporting workers and materials for pyramid construction, offering insight into their geographic and logistical considerations.
- The study shows that natural events such as climate change, tectonic shifts, and human activities, along with environmental factors like desertification and changes in rainfall, have altered the Nile’s landscape, and branches over time, impacting the region’s ecology and water systems.t.
10) KAZA Summit 2024:
- At the KAZA Summit 2024, leaders of the Kavango-Zambezi Trans-Frontier Conservation Area (KAZA-TFCA) decided to oppose the ivory trade ban at the CoP 20 of CITES.
- Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) is an international agreement between 184 governments to ensure that international trade in wild animals and plants does not threaten the survival of the species.
- The convention entered into force in 1975. India has been a CITES Party since 1976.
- All import, export and re-export of species covered under CITES must be authorized through a permit system.
