Supreme Court to examine plea challenging voter roll revision in Bihar

The Supreme Court stated it will examine everything after a group of petitioners, including Lok Sabha Leader of the Opposition Rahul Gandhi, challenged the Special Intensive Revision (SIR) of electoral rolls in Bihar by the Election Commission of India. Petitioners allege the exercise is arbitrary and could lead to mass disenfranchisement of genuine voters, highlighting transparency concerns, impact on marginalized sections, and arbitrary deletions. A three-judge bench headed by Chief Justice B.R. Gavai posted the matter for further hearing after the ECI files its response.

  • The Supreme Court agreed to hear a petition challenging the Special Intensive Revision (SIR) of electoral rolls in Bihar.
  • Petitioners argue that the ongoing revision process is arbitrary and could lead to large-scale disenfranchisement of genuine voters.
  • The ECI maintains that SIR is a routine process to verify and update electoral rolls by cross-checking citizen details.
Exam Points
  • The case is heard by a three-judge bench headed by Chief Justice of India B.R. Gavai.
  • Special Intensive Revision (SIR) is conducted by the Election Commission of India (ECI).
  • The petition raises concerns regarding Article 21 (Right to life and personal liberty) and democratic participation.

Exploring the human genome's dark matter and non-coding DNA

Researchers have made a significant breakthrough in understanding the human genome by revealing that a large portion of non-coding DNA, previously considered junk, plays a crucial role in regulating genes, shaping traits, and influencing disease risk. Published in Nature, the study analyzes non-coding DNA using advanced genomic tools and focuses on regulatory elements that act as switches controlling when, where, and how genes are expressed. This research reframes our understanding of human biology, evolution, and disease, opening new avenues for personalized medicine and targeted therapies.

  • A recent study published in Nature reveals that non-coding DNA plays a vital role in gene regulation and human health.
  • Non-coding DNA acts as regulatory switches that control when and where genes are expressed.
  • The discovery challenges the long-held view that only about 1-2 percent of the genome codes for proteins.
Exam Points
  • The study focusing on non-coding DNA was published in the journal Nature.
  • Only about 1-2% of the genome traditionally codes for proteins, while vast regions consist of non-coding DNA.
  • The research involves international collaboration and advanced genomic tools.

India must lead a green transition in a changing climate: UNEP report

A recent report by the United Nations Environment Programme (UNEP) has warned that the world is likely to cross the 1.5°C warming threshold within the next few years, highlighting the urgent need for faster decarbonization, stronger infrastructure, and increased investment in clean energy. NITI Aayog estimates that 86% of India's building stock will be in place by 2070, underlining the necessity for green construction to combat extreme weather. The report emphasizes that India's green transition can serve as a model for developing nations, provided there is adequate international cooperation and financial support.

  • The UNEP report warns that global warming is likely to exceed the 1.5°C threshold soon, necessitating rapid decarbonization.
  • NITI Aayog estimates that 86% of India's building stock will be established by 2070, requiring sustainable urban planning and green construction.
  • India's agricultural, water resources, and coastal regions are highly vulnerable to extreme weather events.
Exam Points
  • The report was published by the United Nations Environment Programme (UNEP).
  • NITI Aayog estimates that 86% of India's building stock will be in place by 2070.
  • The warming threshold highlighted in the report is 1.5°C.
