CONTEXT – Petitions seeking the inclusion of Dalit Christians and Dalit Muslims and the removal of religion as criterion for inclusion as SCs.

COMMITTEE- The Union government  now formed a 3 member Commission of Inquiry headed by former CJI, Justice K.G. Balakrishnan, to examine whether the Scheduled caste  status can be accorded to Dalits converted to religions other than Sikhism or Buddhism.

The Constitution (Scheduled Castes) Order, 1950- Persons belonging to Hindu, Sikh or Buddhist communities to be categorised as SCs

International Relations                                                           


CONTEXT- UN Human Rights Council refuse to debate violations in China’s Xinjiang region because votes went in favour of China.

  • India  abstained on a resolution at the UNHRC promoting human rights in Sri Lanka but urged the government in Colombo to deliver on commitments towards the Tamil minority.
  • India also abstained on a draft resolution at the UNHRC calling for a debate on the human rights situation in China’s Xinjiang region.
  • India later on addressed the issue of the Uighurs of Xinjiang directly for the first time saying that the community’s human rights should be “respected”.

Who are Uighurs

  • The Uighurs are a predominantly Muslim minority Turkic ethnic group, whose origins can be traced to Central and East Asia.
  • The Uighurs speak their own language, similar to Turkish, and see themselves as culturally and ethnically close to Central Asian nations.
  • China recognises the community only as a regional minority and rejects that they are an indigenous group.
  • Currently, the largest population of the Uighur ethnic community lives in the Xinjiang region of China.
  • A significant population of Uighurs also lives in the neighbouring Central Asian countries such as Uzbekistan, Kyrgyzstan and Kazakhstan.

Uighur Muslims for decades, under the false accusation by the Chinese government of terrorism and separatism, have suffered from abuses including persecution, forced detention, intense scrutiny, surveillance and even slavery.

                                                MINOR FOREST PRODUCE

For kondareddi tribals (Andhra Pradesh)-Bamboo shoots form recipe to health & happiness

  • Bamboo shoots are nutritious and improves their immunity against viral fevers.
  • The tribal people inhabiting in the forest and hill ranges are entitled to collect every form of bamboo tree, which is classified as Minor Forest Produce. They have the right to exploit its commercial value for their livelihood.

What is MFP

  • Section 2(i) of the Forest Rights Act defines a Minor Forest Produce (MFP) as all non-timber forest produce of plant origin and includes bamboo, brushwood, stumps, canes, cocoon, honey, waxes, Lac, tendu/kendu leaves, medicinal plants etc.
  • The Central government had introduced a minimum support price for a selected list of minor produce items in 2011.
  • It aims to provide a social safety net to these underprivileged forest dwellers, and to aid in their empowerment.


  1. The responsibility of purchasing MFP on MSP will be with State designated agencies.
  2. The scheme supports primary value addition as well as provides for supply chain infrastructure like cold storage, warehouses etc.
  3. The Ministry of Tribal Affairs will be the nodal Ministry for implementation and monitoring of the scheme. The Minimum Support Price would be determined by the Ministry with technical help of TRIFED.




CONTEXT- Following the death of 66 children in Gambia, the WHO has raised an alert for four India-manufactured fever, cough and cold syrups, urging people to not use them.

  • Made by Haryana-based Maiden Pharmaceuticals
  • Drug name- Promethazine (Cough syrup)
  • Reason – contaminated with di-ethylene glycol and ethylene glycol, which are toxic for humans and can lead to acute kidney injury and kidney failure in children.
  • India’s explanation- The manufacturers had been given special approval for export against purchase order placed by Gambia. These drugs are not sold in India.
  • EFFECTS- Impact India’s  reputation as the ‘pharmacy of the world.
  • Way forward – India must revisit the regulatory framework to ensure national uniformity for certification, licensing, marketing and export. 

Ethylene glycol

  • A useful industrial compound found in many consumer products. Examples include antifreeze, hydraulic brake fluids, some stamp pad inks, ballpoint pens, solvents, paints, plastics, films,  and cosmetics. It can also be a pharmaceutical vehicle( some vaccines), preservatives.
  • It is an odorless, colorless, flammable, viscous liquid.
  • Ethylene glycol has a sweet taste, but it is toxic in high concentrations


CONTEXT – Experiments with entangled photons, and establishment of pioneering quantum information science that received the Nobel Prize in physics this year, also saw a new theoretical concept by Indian scientists exploring connections between the laws of thermodynamics and Quantum Information Theory (QIT).

  • This  could facilitate harnessing quantum entanglement for futuristic energy storage technology.
  • Theorised a concept called ‘ergotropy’ that represents the amount of extractable work from a system by keeping its entropy (measure of randomness of a system) constant.
  • The idea if harnessed can open pathways for putting quantum batteries to use in a way that is much efficient than its classical counterpart.
  • They have proposed thermodynamic quantities that capture a signature in multipartite quantum systems called ‘genuine multipartite entanglement where several particles behave like a single unit even when they are separated.  
  • According to thermodynamics, thermal equilibrium states are completely passive states as no work can be extracted from such a state even if many copies are available. But the situation becomes more intriguing when the states are entangled.  
  • One can probe the individual parts locally to get useful energy which can further be stored in a battery for later uses.. The difference between work extraction from individual parts and work extraction from the composite system is called ergotropic gap.  
  • Ergotropic gap can be enhanced if the parts of a composite quantum system are prepared in an entangled state.
  • The consequences will be far reaching in terms of mitigating climate change. 
  • Useful resource for several protocols, such as, quantum teleportation, quantum super dense coding, and secure quantum key distribution whose implications deeply impacted physics and computer science.
Caption: Multipartite systems can possess correlations of different types.
1.      The lower one is separable where no entanglement is there in between any two subparts.
2.      Middle one is biseparable where only a subgroup of the particles is entangled.
3.    Topmost one contains most exotic form of quantum correlation – the genuine entanglement.
Caption: (a) Local ergotropic work: The local parts of a composite system are probed individually.
 (b)Biseparable ergotropic work: Different parts of a composite systems are combined and probed to extract work.
(c) Global ergotropic work: This is the most efficient probing where the whole system is addressed for work extraction.


  • Astronomical observatory, any structure containing telescopes and auxiliary instruments with which to observe celestial objects


  • The purpose of an astronomical observatory is to gather information that will lead to an understanding of the nature of the universe and its various components.
  • Among the many celestial bodies examined by astronomical observatories are planets, stars, comets, galaxies, quasars, and nebulae

Ideal location for an observatory

  1. Clean skies
  2. High altitude – “A dry, high-altitude desert is in many ways the ideal location
  3. Complete darkness – To be able to detect stars or traces of cosmic phenomena, such as supernovae or nebulae from light years away, astronomers must be able to catch the faintest slivers of their radiation that often lie outside the range of visible light

Best such location is Hanle, Ladakh.-Two Observatories located – IAO & MACE


  1. Monsoonal clouds in Kavalur ,Tamil Nadu forces Vainu Bappu Observatory (run by Indian institute of astrophysics ) get closed for months
  2. Rainclouds absorb starlight and radiation from cosmic objects, preventing them from being caught on the telescopes of cameras.
  3. High altitude – less oxygen and more prone to mountain sickness.
  4. Light is the enemy – light pollution in which artificial light from cities and home electrification have obscured the natural night sky
  5. Ladakh’s Union Territory status, a government to expand economic opportunities via tourism and the Indian Army expanding its infrastructure development, lighting to bolster its defence at the India-China border which is near Hanle observatory

To counter challenges, the Ladakh government along with the IIA and India’s Scientific Ministries is laying the groundwork to have Hanle declared as an International Dark Sky Reserve by the International Dark-Sky Association(is a United States-based non-profit organization incorporated in 1988 )
