Daily Current Affairs Quiz: September 29, 2023

ANSWER: B

ANSWER: D

ANSWER: C

ANSWER: A

• Recent scientific research has revealed that traits inherited from Neanderthals and Denisovans, another extinct hominin species, continue to influence our health, biology, and even our response to diseases like Covid-19.
• Recent studies have linked Neanderthal DNA to various human traits and diseases. For instance, researchers have found connections between Neanderthal genes and a serious hand disease, the shape of people’s noses, and even our immune response to pathogens.
• The amount of Neanderthal or Denisovan DNA present in modern humans varies depending on geographical location and ancestral lineage.
  • While some African populations have almost no Neanderthal DNA, those from European or Asian backgrounds carry about 1% to 2%.
  • Denisovan DNA is barely detectable in most parts of the world but makes up 4% to 6% of the DNA of people in Melanesia, extending from New Guinea to the Fiji Islands.
• These genetic remnants can have both beneficial and detrimental effects on our health.
  • For example, Neanderthal DNA has been linked to autoimmune diseases like Graves’ disease and rheumatoid arthritis.
  • On the other hand, interbreeding with Neanderthals and Denisovans likely bolstered our ancestors’ immune systems, providing a quick fix to diseases prevalent in Europe and Asia.

ABOUT NEANDERTHALS (HOMO NEANDERTHALENSIS)

• Neanderthals are our closest extinct human relative.
• They lived throughout Europe and parts of Asia from about 400,000 until about 40,000 years ago.
• Physical features include long, low skull with a characteristic prominent brow ridge above their eyes, relatively short and stocky bodies.
• They co-existed with modern humans for long periods of time before eventually becoming extinct.

ABOUT DENISOVANS

• Denisovans are also an extinct species of hominid and were close relatives of Neanderthals.
• They lived lakhs of years ago, coexisting with Neanderthals in some regions, and interbreeding with early modern humans in some cases.
• The Denisovans are a much more recent addition to the human family tree.
• They were first identified as a separate species in 2010, following the discovery of a fragment of a finger bone and two teeth, dating back to about 40,000 years ago, in the Denisovan Cave in Siberia.
• Denisovan fossils are so rare because their population was smaller than that of Neanderthals.

ANSWER: C

• Times Higher Education (THE) has announced results of the 2024 edition of World University Rankings.
• THE has considered 1,904 universities across 108 countries and regions for 2024 rankings.
• In the global list, UK’s University of Oxford is in the top spot, followed by Stanford University and MIT in second and third places.
• This time, Indian Institute of Science (IISc) Bangalore has featured in the 201-250 bracket.
• Four Indian varsities – Anna University, Jamia Millia Islamia, Mahatma Gandhi University and Shoolini University of Biotechnology and Management Sciences – are in the 501-600 bracket.
• A record 91 Indian universities have made it to the list this year making a significant improvement in the country’s rank.
  • Only 75 institutes from India were included in the rankings last year.
• India has now become the fourth best represented nation in the 2024 World University Rankings.
  • India was ranked at the sixth position last year.

ANSWER: B

• The Pension Fund Regulatory and Development Authority (PFRDA) has urged the government to raise the guaranteed pension amount under the Atal Pension Yojana (APY).
• The current sum may not entice potential subscribers to join the scheme.

ABOUT ATAL PENSION YOJANA (APY)

• APY is a contributory scheme aimed at establishing a universal social security system for workers in the unorganised sector.
• APY replaced Swavalamban Scheme.
• Administered by PFRDA under National Pension System.
• Nodal Ministry – Ministry of Finance
• Currently, subscribers between 18 years to 40 years contribute and receive a fixed pension amount ranging from Rs 1,000 to Rs 5,000 after turning 60.
• As of 16 September, APY has 50 million subscribers and Rs 30,694 crore in assets under management (AUM).

ANSWER: C

• Recently Jharkhand’s CM penned a letter to PM urging the acknowledgment of the ‘Sarna’ religious practices among tribal communities.
• He highlighted that the tribal population in the state has decreased from 38 percent to 26 percent over the past eight decades.

ABOUT SARNA FAITH

• Followers of Sarna faith regard themselves as belonging to a distinct religious group, and are nature worshippers.
• The holy grail of the Sarna faith is “Jal (water), Jungle (forest), Zameen (land)” and its followers pray to the trees and hills while believing in protecting the forest areas.
• Believers of Sarna faith do not practice idol worship, nor do they adhere to the concept of the Varna system, heaven-hell, etc.
• The followers are largely concentrated in the tribal belt states of Odisha, Jharkhand, Bihar, West Bengal, and Assam.
• Several surveys and reports have indicated that over 50 lakhs tribal people in the entire country put their religion as ‘Sarna’ in the 2011 census, although it was not a code.

• State-run V O Chidambaranar (VOC) Port, located in Tamil Nadu’s Thoothukudi district, has become the first port in India to handle green ammonia with the arrival of three 20-inch tank containers loaded with the fuel from the Port of Damietta in Egypt for Tuticorin Alkali Chemicals and Fertilisers Ltd.
  • VOC Port is one of the 12 ports owned by the Union government.

About Green Ammonia

• Green Ammonia, referred to as the ‘fuel of the future’, has gained prominence as a cleaner and greener alternative to traditional fossil fuels.
• It is produced through a process that utilizes renewable energy sources, such as wind and solar power, to generate hydrogen, which is then combined with nitrogen to create ammonia.
• This process significantly reduces greenhouse gas emissions compared to conventional ammonia production methods.
• Applications– a clean energy source for ships, power generation and even as a fertiliser.

ANSWER: B

• In 2023, the theme for World Heart Day is “Use Heart, Know Heart”
• The first World Heart Day was celebrated in 1999.
• The date of September 29th was chosen as it marks the anniversary of the foundation of the World Heart Federation, which was established in 1978.
  • World Heart Federation is a global non-governmental organization dedicated to the prevention and control of cardiovascular disease.
