About Neurotoxins:-
IMAGE SOURCE: 5 Neurotoxins Found in Popular Foods | Be Brain Fit
Neurotoxins are synthetic or naturally occurring substances that damage, destroy, or impair the functioning of the central and/or peripheral nervous system.
Neurotoxins may damage neurons, axons, and/or glia resulting in loss of specific nuclei and/or axonal tracts or demyelination.
They may also cause metabolic imbalances that can secondarily affect the central nervous system (CNS).
Many neurotoxins are of external origin, entering the body from environmental sources.
Others, however, are endogenous, being produced and existing within the body.
Examples of endogenous neurotoxins include the neurotransmitters nitric oxide and glutamate. (UPSC CSE: Biological and Toxin Weapons Convention (BTWC) )
Physiological effects:-
Neurotoxins are absorbed through inhalation, ingestion, skin contact, or injection and can have immediate or long-lasting impacts by causing neurons to malfunction or by disrupting interneuron communication.
Certain neurotoxins are highly potent and have been developed into chemical weapons.
Sarin is an organophosphorus compound that is classified as a weapon of mass destruction (UPSC Prelims: Stockholm Convention on Persistent Organic Pollutants (POPs) )
Neurotoxins such as arsenic, chlorpyrifos, DDT (dichlorodiphenyltrichloroethane), ethyl alcohol, fluoride, lead, polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), manganese, mercury, and toluene are major contributors to the prevalence of neurobehavioral disorders.
The impact of some neurotoxins, such as lead and ethyl alcohol, is well-documented.

Article 142
Syllabus
Prelims –Polity
Context: In a recent ruling, the Supreme Court rules that it can directly grant a divorce to couples under Article 142.
About Article 142:-
It deals with the enforcement of decrees and orders of the Supreme Court.
Article 142 provides discretionary power to the Supreme Court as it states that the Supreme Court in the exercise of its jurisdiction may pass such decree or make such order as is necessary for doing complete justice in any cause or matter pending before it. (UPSC PRELIMS: Understanding Article 142)
Subsection 1 of Article 142 provides a unique power to the Supreme Court, to do complete justice between the parties.
According to some eminent jurists, natural justice is above law, and the Supreme Court shall have full right to pass any order that it considers just. (UPSC MAINS: alternate dispute resolution mechanism in India.)
Therefore, the Supreme Court shall exercise these powers and will not be deterred from doing justice by the provision of any rule or law, executive practice or executive circular or regulation etc.
The framers of the Constitution felt that this provision is of utmost significance to those people who have to suffer due to the delay in getting their necessary reliefs due to the disadvantaged position of the judicial system. (UPSC CSE: Judicial Accountability )
Significance of Article 142:-
Prevents Injustice: It provides a special and extraordinary power to the Supreme Court to do complete justice to the litigants who have suffered traversed illegality or injustice in the proceedings.
Uphold citizen’s rights: Article 142 has been invoked for the purpose of protecting the rights of the different sections of the population.
Check on Government: Works as a system of checks and balances with the Government or Legislature.
Cases where the Supreme Court has invoked its plenary powers under Article 142:-
Manohar Lal Sharma v. Principal Secretary(2014): The Supreme Court can deal with exceptional circumstances interfering with the larger interest of the public in order to fabricate trust in the rule of law.
A.R. Antulay v. R.S. Nayak(1988): The Supreme Court held that any discretion which is given by the court should not be arbitrary or in any way be inconsistent with provisions of any statute laid down.
Union Carbide Corporation v. Union of India (1989): In Bhopal Gas Tragedy Case, the court ordered to award of compensation to the victims and placed itself in a position above the Parliamentary laws.
Siddiq v. Mahant Suresh Das (2019): Popularly known as the Ayodhya dispute, the Supreme Court exercised the powers mentioned under Article 142 of the Constitution.

Shilabhattarika
Syllabus
Prelims –Art and Culture
Context: Recent decoding of Copper plates sheds light on the celebrated ancient Sanskrit poetess Shilabhattarika.
About Shilabhattarika:-
Shilabhattarika was a Sanskrit poetess who lived in the 9th century.
M. B. Padma, a scholar of the University of Mysore, speculates that she may be the same as Shila-maha Devi, the queen of the 8th-century Rashtrakuta ruler Dhruva.
His theory is based on the fact that the suffix “Bhattarika” attached to the poet’s name indicates her high social status and that the queen is known to have made generous grants to scholars.
The 10th-century poet Rajashekhara praises Shilabhattarika as a leading figure of the Panchali literary style (one of the four major contemporary literary styles)
The other three are Vaidharbhi, Gaudi, and Lati.
According to Rajashekhara, the Panchali style can be traced to the works of Shilabhattarika, and possibly to some of the works of the 7th-century poet Bana.
Shilabhattarika has been quoted by several classical Sanskrit literary critics, and her verses appear in most major Sanskrit anthologies. (UPSC CSE: Central Sanskrit University Bill)
She is known to have written at least 46 poems on topics such as “love, morality, politics, nature, beauty, the seasons, insects, anger, indignation, codes of conduct, and the characteristic features of various kinds of heroines.“
However, most of her works are now lost.
Only six of her short poems are extant.
Sharngadhara-paddhati, a 14th-century anthology, praises her and three other female poets in the following words.
Shilabhattarika, Vijja, Marula, and Morika are poetesses of renown with great poetic genius and erudition. (UPSC CSE: Examining the contribution of women poets towards India’s Bhakti literature.)

Key provisions and challenges of Forest Rights Act, 2006
Syllabus
Mains – GS 2 (Governance) and GS 3 (Environment)
Context: The National Commission for Scheduled Tribes (NCST) has issued a notice to district authorities in Andaman and Nicobar islands on grounds that the Great Nicobar Island (GNI) Project violated norms under the Forest Rights Act (FRA), 2006.
About The Forest Rights Act, 2006:
Source: The Hindu
The Forest Rights Act, 2006 (also known as the Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act) is a landmark legislation in India that seeks to recognise and vest forest rights and occupation in forest land in forest-dwelling Scheduled Tribes and Other Traditional Forest Dwellers.
The Act aims to rectify historical injustices done to forest-dwelling communities and recognise their role in forest conservation.
Important provisions of the Act and their impact:
FRA enacted in 2006 recognises the rights of forest-dwelling tribal communities (FDST) and other traditional forest dwellers (OTFD) to forest resources on which these communities were dependent for a variety of needs, including livelihood, habitation and other sociocultural needs.
It recognizes and vest the forest rights and occupation FDST and OTFD who have been residing in such forests for generations.
It strengthens the conservation regime of the forests while ensuring livelihood and food security of the FDST and OTFD.
The Gram Sabha is the authority to initiate the process for determining the nature and extent of Individual Forest Rights (IFR) or Community Forest Rights (CFR) or both that may be given to FDST and OTFD.
Rights Under the Forest Rights Act:
Title rights:
It gives FDST and OTFD the right to ownership to land farmed by tribals or forest dwellers subject to a maximum of 4 hectares.
Ownership is only for land that is actually being cultivated by the concerned family and no new lands will be granted.
Use rights:
The rights of the dwellers extend to extracting Minor Forest Produce, grazing areas
Relief and development rights
To rehabilitate in case of illegal eviction or forced displacement and to basic amenities, subject to restrictions for forest protection.
Forest management rights:
It includes the right to protect, regenerate or conserve or manage any community forest resource which they have been traditionally protecting and conserving for sustainable use.
Challenges
Administrative Apathy
Implementation of the act remains the biggest challenge as acts related to the environment are not entirely compliant with the law, illegal encroachments have happened as much as that claims have been unfairly rejected.
As tribals are not a big vote bank in most states, governments find it convenient to subvert FRA or not bother about it at all in favour of monetary gains.
Lack of Awareness
Unawareness at the Lower level of forest officials who are supposed to help process forest rights claims is high and majority of the aggrieved population too remains in the dark regarding their rights.
The forest bureaucracy has misinterpreted the FRA as an instrument to regularise encroachment instead of a welfare measure for tribals.
Dilution of Act
Certain sections of environmentalist raise the concern that FRA bend more in the favour of individual rights, giving lesser scope for community rights.
Community Rights effectively gives the local people the control over forest resources which remains a significant portion of forest revenue making states wary of vesting forest rights to Gram Sabha.
Reluctance of the forest bureaucracy to give up control
There has been deliberate sabotage by the forest bureaucracy, both at the Centre and the states, and to some extent by big corporates.
The forest bureaucracy fears that it will lose the enormous power over land and people that it currently enjoys, while the corporates fear they may lose the cheap access to valuable natural resources.
Institutional Roadblock
Rough maps of community and individual claims are prepared by Gram Sabha which at times often lack technical knowhow and suffers from educational incapacity.
Intensive process of documenting communities’ claims under the FRA makes the process both cumbersome and harrowing for illiterate tribals.
Way Forward:
It is important to develop a detailed strategy of training and capacity building of people responsible for implementing the FRA, such as Panchayats, Gram Sabha, village level Forest Rights committee
The relevant maps and documents should be made available to the Forest rights committee and claimants to simplify the task of the Gram Sabha in identifying and filing claims for individual and community rights.
The Centre should take a more proactive role in pushing states to honor a law that could change the lives of millions.
