65 lakh names missing from Bihar draft roll as Election Commission faces scrutiny

Why in news: The Election Commission of India (ECI) is facing scrutiny over the exclusion of 65 lakh names from the August 2025 Bihar draft roll and technical hurdles in the appeals process in West Bengal.

In Bihar, 65 lakh names were missing from the August 2025 draft roll due to reasons like deaths, migration, and duplicate entries. In West Bengal, 27 lakh names were deleted during adjudication, leading to 22 lakh appeals.

Prelims pointers (5)

BodyElection Commission of India (ECI) is responsible for the mass revision of electoral rolls.
FactIn Bihar, 65 lakh names were missing from the August 2025 draft roll.
FactIn West Bengal, 27 lakh names were deleted and 22 lakh appeals were filed.
FactIn Aland, Karnataka, only 24 of 6,018 deletion applications were accepted.
FactMaharashtra's 2024 turnout rose from 58.22% to 66.05%.

Mains angle

Q. Discuss the importance of transparency and grievance redressal mechanisms in the maintenance of electoral rolls to ensure inclusive democratic participation.

Transparency gap: Need for public disclosure of reasons for exclusion to allow for verifiable challenges.
Technological bottlenecks: Issues with appeals portals hindering the timely restoration of wrongfully deleted names.
Historical inclusivity: Ensuring registration of women in their own right to prevent systemic disenfranchisement.

IIT Madras centre creates 3D maps of 100 human brains from foetus to 85-year-olds

Why in news: The Sudha Gopalakrishnan Brain Centre at IIT Madras launched a project to create 3D maps of 100 human brains from foetus to 85-year-olds to understand cellular-level structural changes across the lifespan.

The project, led by Professor Mohanashankar Sivaprakasam, uses sections between 10 and 20 microns to reconstruct 3D models. It aims to create a reference map of brain structures and cells to aid in understanding diseases and planning surgeries.

Prelims pointers (5)

S&TSudha Gopalakrishnan Brain Centre is located at IIT Madras.
FactThe project involves mapping 100 human brains ranging from foetus to 85-year-olds.
FactBrain sections for mapping are between 10 and 20 microns thick.
FactAn adult brain can yield between 8,000 and 10,000 sections for mapping.
BodyThe centre collaborated with over 10 institutions, including CMC Vellore, and released DHARANI and C-STROKE in 2025.

Mains angle

Q. Discuss how high-resolution neuro-mapping and cellular-level structural analysis can revolutionize personalized medicine and surgical planning in India.

Diagnostic precision: Transitioning from conventional living-patient imaging to high-resolution cellular reference maps for disease pathology.
Neuro-evolutionary research: Addressing the lack of longitudinal data on brain structural changes from foetus to old age.
Technological sovereignty: Development of indigenous industrial-scale sectioning and imaging systems for neuroscience.

Kerala paddy fields drop 80% as Revenue Department earns ₹1,606 crore from regularisation

Why in news: The Department of Revenue earned ₹1,606 crore from regularising paddy land conversions despite the Kerala Conservation of Paddy Land and Wetland Act, 2008.

Kerala's paddy fields declined from 8.82 lakh ha in 1974-75 to 1.76 lakh ha in 2024-25. The LSGD and CAG identified administrative failures and legal loopholes in the land conversion process.
