1. What are βbio-computersβ and how do they function?
Syllabus: Science and Technology- developments and their applications and effects in everyday life
Prelims: About Bio-computers
Mains: Bio-computers – functioning, benefits, and challenges associated with their development.
Context:
Researchers at Johns Hopkins University (JHU) have come up with a plan for a new area of research named βorganoid intelligenceβ, which aims to create βbio-computersβ.
Background
- Understanding the functioning of the human brain has been one of the most complex challenges for researchers across the world.
- Researchers have resorted to the use of rat brains to examine or research various neurological disorders traditionally.
- Recently, the researchers at JHU have come up with a technique for developing βbio-computersβ from βbrain organoidsβ or βmini brainsβ.
Bio-computers
- Researchers are developing 3D cultures of brain tissue in the lab which are called brain organoids or mini brains.
- Mini-brains, which are up to 4 mm in size, are developed using human stem cells and thus they have the ability to capture various functional and structural features of a human brain.Β
- Such brain cultures that are created or developed are then coupled to the real-world through various sensors and input/output devices.
- Researchers at the JHU have developed a technique wherein brain organoids are integrated with modern computing technologies to create βbio-computersβ.Β
- Plans are in place to also integrate rain organoids or mini brains with machine learning (ML) techniques by developing such organoids inside flexible structures affixed with multiple electrodes (similar to the ones used to record EEG readings).Β
- Such a mechanism will help record the firing patterns of various neurons and deliver electrical stimuli to mimic sensory stimuli.Β
- The following response pattern of the neurons and their effect on human behaviour will be analysed by ML techniques.Β
- Furthermore, developing brain organoids or mini brains using the stem cells of patients with neurodegenerative or cognitive disorders and analysing the data on brain structure, can provide key insights.
Functioning of Bio-computers
- Recently, researchers transplanted human brain organoids into rat brains where they were found to have formed connections with the rat brain which would provide the much needed blood circulation.
- These organoids were transplanted into the visual system and when flash light was shown to the rats as part of the experiment, the human neurons were found to be activated.
- This shows that the human brain organoids were functioning actively.Β
- Scientists believe that the advancement of this system will help significantly understand the biological basis of human cognition, learning, and various neurological disorders.
Key challenges
- Integrating brain organoids with various sensory inputs which mimic realtime touch, smell, vision, etc. would be a complex task that requires a significant amount of investment, technological expertise and sophisticated laboratories.
- Also, such human brain organoids are still tested in the rat-brain microenvironment and the effects of drugs in this case will only show behavioural changes in rats, which is not sufficient and there is a need for developing more human-relevant systems or models.
- Further, another key challenge would be enabling long-term memory of such systems.
Path ahead
- At present, brain organoids are being developed with a diameter of less than 1 mm and fewer than 1,00,000 cells, which make it about three-millionth the size of an actual human brain.Β
- There is a need for scaling up the brain organoid in order to improve and better its computing capacity.
- Scientists are working on adopting such brain organoids and Bio-computers in developing drugs for diseases such as autism and Alzheimerβs.
Nut graf: Studying the human brain has always been a complex process and neuroscientists study the brain of the lab mouse with the hope of understanding the basic principles of the human brain. However, the development of βbio-computersβ with the help of organoid intelligence techniques is expected to revolutionise neuroscientific studies.

1. Utilising India’s moment under the diplomatic sun
Syllabus: Bilateral, Regional & Global Groupings & Agreements Involving India and/or Affecting India’s Interests
Mains: Opportunities and challenges for India with its growing influence in geopolitics.
Context: This article discusses Indiaβs recent strides in international fora.
Indiaβs Moment under the Sun:
- India hosted the G-20 Foreign Ministers meeting, the G-20 Finance Ministers meeting, the Quad Foreign Ministers meeting, Raisina dialogue and βVoice of Global South Summitβ in 2023.
- Indiaβs pivotal position at the G-20, the Quad, the Shanghai Cooperation Organisation (SCO) and the Global South today has given it a surge in stature and reputation.Β
- The rise of contemporary India as a pivotal power in world politics has been a long-awaited moment, with its culture, history, demography, and economic strength providing a solid foundation for its role.Β
- While Indian leaders from pre-Independence days have often spoken of India’s potential in the world, New Delhi was weak for most of its history to assert itself.Β
- The concern over an aggressively rising China has pushed global leaders to explore geopolitical alternatives in the Indo-Pacific region. Therefore, for New Delhi, this is its moment under the sun and the realisation of a long-awaited pivotal power moment.
Treading the fault-lines:
- While India’s leadership role in world politics has been anticipated for a long time, its rise as a pivotal power has also brought new challenges.Β
- India’s strategic interests in the Indo-Pacific region have also put it in a complex position. While India wants to maintain its strategic autonomy, it also needs to balance its relationship with the US and its growing economic ties with China.Β
- For instance,Β India is the chair of both the United States/West-led G-20, and the China-centred SCO at the same time.
- On the Ukraine war, India has not alienated, directly or indirectly, any of the parties involved in the war in a big way.
- Additionally, India’s dependence on energy supplies from the Gulf countries has also made it vulnerable to regional conflicts.
- India’s growing power in global politics has put it in a precarious position. However, IndiaΒ is balancing the language of revisionism and status quoism in the same breath.
Indiaβs Aspirations:
- India’s aspirations in geopolitics have been long-standing and multifaceted. As one of the fastest-growing major economies in the world, India has been seeking a more significant role in global affairs commensurate with its economic and demographic weight.Β
- India also seeks to play a more significant role in global governance and shape the rules-based international order.Β
- As Indiaβs chances of getting permanent membership in the United Nations Security Council (UNSC) appear slim, it has been advocating for more inclusive and flexible forums such as the G-20.
- At a recent G-20 Foreign Ministers meeting, Indian Prime Minister Narendra Modi criticised the dysfunctionality of the UNSC and argued for the importance of the G-20 in global governance.Β
- Despite the meeting ending without a joint statement due to the ongoing Ukraine conflict, it was a success in bringing together the warring parties in one room, highlighting the G-20’s potential to facilitate meaningful dialogue on pressing global issues.
- One of the key aspirations of India in geopolitics is to become a regional power in Asia, particularly in the Indian Ocean region. India aims to expand its strategic influence in the region by building partnerships with other major powers, such as the US, Japan, and Australia.
Challenges:
- Indiaβs moment in the sun, as it seeks to assert itself on the global stage, comes with its own set of challenges.Β
- With its chairmanship of the G-20 and the SCO coming to an end this year, India must contend with Beijing’s attempts to prevent it from taking over the leadership of the Global South.Β
- India’s diplomatic language and framing also pose a challenge. The need for finesse and authority in diplomatic language, rather than aggression, is crucial for building long-lasting partnerships.Β
- Another challenge is the need to balance opposing interests and powers. While India has the opportunity to strengthen strategic partnerships and seek geopolitical concessions, it must also avoid indecisiveness and make sure that it forms strong partnerships that can support it in case of conflicts.
- India must also avoid the temptation to use its diplomatic successes for domestic political ends. Instead, it must focus on strengthening its place in the global community and making lasting gains in geopolitical power.
Nut Graf: Β India has had a busy year in international diplomacy , having hosted various global summits and meetings in 2023. India’s increasing influence and importance on the global stage have brought both opportunities and challenges. Despite the challenges, India’s aspirations in geopolitics remain to become a regional power in Asia and shape the rules-based international order.
2. Libyaβs outlook remains bleak
Syllabus: Effect of Policies & Politics of Developed & Developing Countries on India’s Interests
Mains: International Efforts to solve Libyan Crisis
Context: On February 28,2023, the UN special representative for Libya, Abdoulaye Bathily announced plans to create a new mechanism in support of crucial elections in the country.
Libya after Gaddafi:
- After the death of Libyan dictator Muammar Gaddafi in 2011, Libya experienced a period of political instability and conflict.Β
- Various factions vied for power, and a civil war erupted between the internationally recognized Government of National Accord (GNA) and the Libyan National Army (LNA) led by General Khalifa Haftar.
- The GNA, based in the capital city of Tripoli, was formed with the support of the United Nations and the international community. It claims executive authority.
- It was meant to be a temporary government until new elections could be held. However, the GNA struggled to establish its authority over the entire country and faced challenges from other armed groups and militias.
- The House of Representatives (HOR) in Tobruk under General Haftar, who had previously served under Gaddafi, led the LNA in a campaign to take control of the country. Haftar’s forces controlled much of the eastern and southern parts of Libya, including the major oil fields.Β
- The growth of the Libyan economy is projected to be 17.9% this year, the highest in Africa, but despite this some estimates show that nearly a third of Libyans, especially in the south, live at, or below, the poverty line.
- Most Libyan politicians have amassed extraordinary wealth which has resulted in the situation called βredistributive kleptocracy.β
Ongoing conflict:
- The conflict between the GNA and the LNA continued for several years, with various countries and foreign actors supporting different sides.
- Gulf Cooperation Council (GCC) members Qatar and the UAE backed rival factions in the civil conflict.
- Qatar supported the Islamist government in Tripoli, while the UAE, backed by Egypt, backed the HOR in Tobruk.
- To obtain a military settlement, from 2014, the UAE supported General Khalifa Haftar.
- From April 2019, he launched a major assault on Tripoli. The UAE backed the offensive with hundreds of drone strikes, weaponry and jet fuel, and funded Sudanese and Russian mercenaries as part of his forces.
- This was countered with the entry of Turkey.Β
- In November 2019, Turkey signed an agreement with Tripoli administration and provided it with drones, air defence systems and mercenaries from pro-Turkish militia groups in Syria.Β
- In October 2020, a ceasefire agreement was reached between the GNA and the LNA, leading to the establishment of a new interim government called the Government of National Unity (GNU).Β
- The GNU is led by interim Prime Minister Abdul Hamid Dbeibah.Β
- In February 2022, the HOR declared that the term of the incumbent prime minister, Abdul Hamid Dbeibah was over and appointed former Interior Minister Fathi Bashaga in his place.Β
- But Mr. Dbeibah refused to give up his position, forcing Mr. Bashaga to function from the town of Sirte.Β
- In February 2023, the UN representative for Libya announced the setting up of a βhigh-level steering panel to bring together relevant stakeholders who would adopt a legal framework for elections, address matters relating to code of conduct and election security, and prepare a time-bound road map for elections to be held in 2023.
Road Ahead:
- The involvement of external actors is expected to play a critical role in Libya’s future.Β
- The UAE has recently switched its allegiance from the Tobruk administration to Mr. Dbeibah in Tripoli, leading Mr. Dbeibah to exclude Islamists from his government and offer the UAE lucrative contracts in energy, construction, and telecom.
- Conversely, Qatar has shifted its support to Tobruk, establishing ties with Mr. Haftar and officers from previous anti-Gaddafi groups, as well as members of the HOR.Β
- Meanwhile, Qatar and Egypt have improved their relationship since October 2022, with Qatar seen as a significant player in Cairo to mitigate the Islamist challenge from Tripoli.
- Russia, through its Wagner Group mercenaries, has entrenched itself in Libya and views the country’s oil-rich resources as an invaluable base to extend its influence in Africa.
- Libyan politicians, aligned with various foreign groups, seem to hinder the unification of their country and the establishment of a democratic order and a more equitable distribution of national wealth which might result in re-emergence of military conflict in the country.
Nut Graf: Despite the ceasefire and the establishment of the Government of National Unity, Libya continues to face challenges, including ongoing violence, economic instability, and a lack of basic services. The international community continues to support the country’s transition to a stable and democratic government.

1. The hardships of a career in Ayurvedic Practice
Syllabus: Issues Relating to Development & Management of Social Sector/Services-Health
Mains: Key Challenges associated with Ayurveda
Context: This article discusses hardships of a career in Ayurvedic Practice.
Introduction:
- Ayurveda is a traditional system of medicine that originated in India thousands of years ago. It is based on the principles of balancing the body, mind, and spirit to achieve optimal health and wellness.Β
- While it can be a rewarding career for those who are passionate about natural health and healing, it can also present its share of challenges and hardships.
- Despite the publicity campaigns to promote Ayurveda, Yoga, Unani, Siddha and Homeopathy (AYUSH), there is a trust-deficit in these systems.Β
Challenges:
- There is widespread scepticism in the public mind about the soundness of Ayurvedic theories and the fruitfulness of its practices.Β
- The Ayurveda establishment has failed to keep pace with the intellectual and scientific advances of the times as treatments are made to escape experimental scrutiny because of their supposed rootedness in such theories.
- Thus, a major reason for the trust-deficit in Ayurveda is its diminished evidence-based quality.
- That Ayurveda treatments are slow to heal as Ayurveda on patient benefit and not just on instant patient gratification. Sustainability of treatments requires a gradual transition from illness to wellness.Β
- An Ayurveda practitioner has to depend on himself to discover treatments and approaches that actually work. The process involves a lot of trial and error with patients and predictably leads to an erosion of the practitionerβs reputation.
- Ayurveda can be used safely and efficiently only in about 60%-70% of primary-care illnesses. Ayurveda practitioners would necessitate complementing Ayurveda with modern medicine.Β
- However, most States prohibit the practice of modern medicine by Ayurveda graduates.
- Ayurveda is still not widely recognized as a mainstream medical practice in many parts of the world. Additionally, the lack of standardisation in training and education can make it difficult for practitioners to be recognized and respected.
- In many countries, Ayurvedic practice is not regulated by the government, which can lead to unscrupulous practitioners offering substandard or even dangerous treatments.
- With the rise of natural and alternative medicine, there is an increasing number of Ayurvedic practitioners, which can lead to stiff competition in the market
Way Forward:
- Ayurveda graduates can contribute enormously towards rejuvenation of primary care in India if trained properly.Β
- Government must promote a vigorous evidence-based appraisal of Ayurvedic theories and practices in order to sift the usable from the obsolete.
- Government mustΒ invest in providing high-quality education and training from reputable institutions which meet the standards set by it.
- Practitioners must obtain the necessary licences and certifications to practise Ayurveda legally. They can Join professional organisations such as the National Ayurvedic Medical Association (NAMA) to stay up-to-date on industry developments and standards.
- The government can provide financial support and incentives to Ayurvedic businesses, including funding for research and development, and tax incentives for Ayurvedic products.
- The government can launch public awareness campaigns to educate people about the benefits of Ayurveda and encourage them to adopt Ayurvedic practices as a part of their daily lives.
- The government can also collaborate with other countries to promote Ayurveda globally. This can include joint research studies, training programs, and exchange programs for Ayurvedic practitioners.

Nut Graf: Although practising Ayurveda can be a rewarding career for those passionate about natural health, it comes with its share of challenges.Lack of standardisation in training and education can make it difficult for practitioners to be recognized and respected. If trained properly, Ayurveda graduates can contribute significantly to the rejuvenation of primary care in India.
F. Prelims Facts
1. United Nations High seas treaty
Syllabus: GS-2; International Relations; Regional and global agreements involving India.
Prelims: About High Seas Treaty
Context:
The United Nations members have agreed on a unified treaty to safeguard biodiversity on the high seas for the first time.
United Nations High Seas Treaty
- The treaty on the high seas which was under discussion for about 15 years was finally agreed upon in the U.N.-led negotiations that took place in New York.
- The high seas treaty is a legally binding pact that aims to conserve and ensure the sustainable use of ocean biodiversity.
- The U.N. Convention on the Law of the Sea (UNCLOS) came into force in 1994 and the High Seas Treaty is an updated framework to protect marine life in the regions outside national boundary waters known as the high seas.
- The treaty will facilitate the establishment of a new body to manage and look after the conservation of ocean life.
- The treaty also provides a legal framework for establishing marine protected areas (MPAs) to protect against the loss of wildlife and share out the genetic resources of the high seas.
- The High Seas Treaty places 30% of the world’s oceans in potected areas.
- The treaty will introduce arrangements for sharing marine genetic resources like biological material from plants and animals in the ocean.Β
- The treaty further puts in place various rules for conducting environmental impact assessments for commercial activities in the oceans.
2. Megha-Tropiques-1 (MT1) satellite
Syllabus: GS-3; Science and Technology; Awareness in the field of space
Prelims: Megha-Tropiques-1 (MT1) satellite
Context:
The Indian Space Research Organisation (ISRO) is undertaking a controlled re-entry of the decommissioned Megha-Tropiques-1 (MT1) satellite on March 7th, 2023.
Megha-Tropiques-1 (MT1) satellite
- The Megha-Tropiques-1 (MT1) satellite was launched in October 2011 through ISROβs Polar Satellite Launch Vehicle (PSLV) from the Satish Dhawan Space Centre, Sriharikota.
- The launch of MT1 Satellite was a joint satellite venture of ISRO and the French space agency.
- The key objective of the satellite was to study tropical weather and climate conditions and provide data services to support regional and global climate models till 2021.
- MT1 Satellite has provided key scientific data about the role of the water cycle on the tropical atmosphere, with data such as the influence of condensed water in clouds, water vapour in the atmosphere, precipitation, and evaporation.
- The Megha-Tropiques had day, night and all-weather viewing capabilities.
- The payload of the satellite consisted of:
- Microwave Analysis and Detection of Rain and Atmospheric Structures (MADRAS)
- Sounder for Probing Vertical Profiles of Humidity (SAPHIR)
- Scanner for Radiation Budget (ScaRaB)
- Radio Occultation Sensor for Vertical Profiling of Temperature and Humidity (ROSA)
- In April 2022, ISRO announced the end of the mission for the MT1 satellite due to the issues with the attitude control sub-system.Β
- As per UN/IADC space debris mitigation guidelines, it is recommended that a Low Earth Orbit (LEO) object at its end-of-life should be deorbited preferably through controlled re-entry to a safe impact zone, or by bringing it to an orbit where the orbital lifetime is less than 25 years.
- The re-entry experiment of MT1 has been undertaken as a part of the ongoing efforts as this satellite with sufficient left-over fuel offered a unique opportunity to test the relevant methodologies.
G. Tidbits
1. βRegulatorβs proposal on Rajasthan power lines flouts SC orders, threatens bustardβ
- The Central Electricity Authority (CEA) has recently come up with a proposal that only power lines below 33kV must be placed underground and the rest are to be fitted with bird-diverters.
- This move is expected to help solar power projects in Rajasthan but hinder the conservation efforts for safeguarding the critically endangered Great Indian Bustards which is the State Bird of Rajasthan.
- Conservationists and environmental experts have raised concerns regarding the move and say that the move could lead to the βextinctionβ of the bird.
- In 2019, environmentalists approached the Supreme Court, which in 2021 ordered all the low-voltage power lines in Thar and Kutch deserts be pushed underground.
- High-tension power lines in Rajasthan and Gujarat from solar plants lie on the flight path of the birds and this issue requires immediate attention as only about 150 Great Indian Bustards survive currently.
- A large number of power lines from Rajasthanβs solar projects have a rating above 33kV and they are expected to pass through the priority and potential habitats of the Great Indian Bustards.Β
- Thus the courtβs order would have required several existing and proposed lines to move underground, which aggravates the cost of supplying solar power.
2. Government approves launch of IFFCOβs nano DAP fertiliser
- The Indian Farmers Fertiliser Cooperative Limited (IFFCO), which introduced nano liquid urea in 2021 announced that the government has approved the launch of its nano DAP (di-ammonium phosphate) fertiliser in the market.
- The Indian Prime Minister has said that the approval of nano DAP fertiliser is an important step towards making life easier for farmers.
- The introduction and approval of nano DAP fertiliser are also seen as a big step towards self-reliance (aatma nirbharta) in the fertiliser sector as India imports DAP and MoP (muriate of potash) in huge quantities to meet its domestic demand.
- IFFCO is also planning to launch nano potash, nano zinc and nano copper fertilisers.

3. Sri Lanka fishermen βfiercely opposeβ proposal to issue licence to Indian fishermen
- The Foreign Minister of Sri Lanka had told the Parliament that licences could be possibly issued to Indian fishermen, as part of Sri Lankaβs efforts to find a solution to the fisheries conflict through βcordialβ bilateral talks.Β
- However, Sri Lankaβs northern fishermen have opposed the governmentβs proposal to issue licences to Indian fishermen to enter Sri Lankan waters as it would be a serious setback to their 15-year-long struggle.
- Further, the fisherman communities have also urged the Sri Lankan government to fully implement laws that ban bottom trawling and illegal fishing.
- A Bill against bottom trawling was passed by Parliament in 2017 and legislators across parties had agreed that no permits must be issued to Indian trawlers.
- The fisheries conflict between the fishermen of Sri Lanka and India on either side of the Palk Strait has remained a key issue in the bilateral ties between the two countries.Β
- The Tamil fishermen of Sri Lanka have protested against Indian trawlers fishing along their coastline as they believe that Indian trawlers have destroyed marine biodiversity and their livelihoods.
- The Indian government had proposed the licensing system as a possible solution to the issue.
