Researcher have successfully mapped the entire brain of an adult fruit fly, marking the first time researchers have created such a detailed map of an adult animal’s brain.
How Was the Fruit Fly Brain Mapped?
The process of mapping Fruit Flies (Drosophila melanogaster) brain began in 2013.
Scientists dunked the brain of an adult fruit fly in a chemical bath, hardening it into a solid block.
This process involved 7,050 sections of the brain and produced 21 million photos to map the entire brain.
The first high-resolution image of the brain was created more than a decade after the work started.
Key findings
Scientists identified more than 50 million connections between 139,000 neurons (brain nerve cells).
They classified the cells into 8,453 distinct types, making it the largest catalogue of cell types in any brain.
The research gave insights into how different types of cells function and how the fruit fly’s eyes process motion and color.
A group of “hub neurons” was discovered, which may help speed up information flow.
Significance of the Work
Although the human brain is more complex, the logic of howneurons communicate is similar between fruit flies and humans.
Fruit flies are a valuable model system for neuroscience. Their brains solve many of the same problems that human brains do.
It could help in understanding and treat mental health conditions like Parkinson’s and depression.
The mapping of the fruit fly’s brain raises hopes that scientists will eventually be able to map the entire human brain.

The Supreme Court declared caste-based discrimination in prisons unconstitutional, ordering immediate reforms in jail manuals nationwide to uphold inmates’ dignity, equality, and non-discrimination rights.
What specific caste-based practices in prison manuals were deemed unconstitutional by the SC?
Work Assignments Based on Caste: The assignment of menial tasks like cleaning and sweeping to marginalized castes (e.g., SCs, STs, DNTs) while reserving cooking roles for higher castes was ruled unconstitutional.
This violated Articles 14 (Right to Equality) and Article 15 (Prohibition of Discrimination on Grounds of Religion, Race, Caste, etc.).
Caste-based Classification of Labour: The court struck down provisions in prison manuals that classified inmates into different labour roles based on their caste, calling it a form of “untouchability” and caste hierarchy.
References to ‘Scavenger Class’: The reference to specific castes as the “scavenger class” was condemned as reinforcing caste stereotypes, and the court ruled such practices unconstitutional under Article 17 (abolition of untouchability).
Assignment of Hazardous Tasks: Marginalized prisoners forced to clean sewers and tanks in unsafe conditions was also ruled a violation of their dignity under Article 21 (Right to Life with Dignity).
How does the ruling reflect the broader implications of caste discrimination in society?
Historical and Societal Caste Biases: The ruling emphasized that caste-based discrimination in prisons is a remnant of colonial and pre-colonial oppressive systems, designed to dehumanize marginalized groups.
Reinforcement of Stereotypes: The court noted that prison rules, by assigning certain jobs to marginalized castes, indirectly perpetuate historical stereotypes and social hierarchies, harming personal growth and development, and fostering caste prejudices.
India’s prisons face other challenges too:
Overcrowding: In 2016, India’s prisons were 20% over capacity, with some prisons over 500% capacity. Overcrowding can lead to poor living conditions and the spread of disease.
Poor hygiene and Custodial torture: Prisoners face physical abuse and sexual abuse, and police may also torture prisoners. Prisons are underfunded, which leads to poor infrastructure, inadequate food, and insufficient clothing.
Understaffing: 33% of prison official positions are vacant. Prison management is a state subject, so prison rules vary by state.
Ineffective bail system: The bail system contributes to the crisis of undertrial incarceration.
What are the actions mandated by the SC?
Reform of Prison Manuals: All states and Union territories must revise their prison manuals within three months to align with the judgment, eliminating discriminatory provisions.
The Union government is required to update the Model Prison Manual 2016 and the Model Prisons and Correctional Services Act 2023 within the same period.
Removal of Caste-Based Work Assignments: The court ordered that no inmate be subjected to work or housing arrangements based on their caste. The caste column in registers of undertrial and convicted prisoners must be deleted.
Prohibition of Hazardous Work: The court mandated that manual scavenging or hazardous cleaning of sewers or septic tanks in prisons be prohibited, in line with the 2013 law banning manual scavenging.
Arrest Guidelines for DNTs: The court called for strict adherence to guidelines (from Arnesh Kumar Vs State of Bihar and Amanatullah Khan Vs Commissioner of Police, Delhi cases) to prevent arbitrary arrests of denotified tribe members.
Compliance Oversight: The court initiated suo motu proceedings to monitor the implementation of these reforms and ordered states and the Union government to submit compliance reports, ensuring sustained oversight.
Conclusion: The Supreme Court’s landmark ruling ends caste-based discrimination in prisons, mandating nationwide reforms in jail manuals, safeguarding inmates’ dignity, and promoting equality by eliminating discriminatory caste-based practices and work assignments.

Q Caste system is assuming new identities and associational forms. Hence, the caste system cannot be eradicated in India.” Comment. (UPSC IAS/2018)
With escalating tensions between Iran and Israel, India’s Ministry of External Affairs she emphasized the need to prevent regional escalation, urging all parties to resolve issues through dialogue and diplomacy for stability.
Can India act as a mediator in the Iran-Israel conflict?
India maintains strong strategic and economic ties with both Israel and Iran, allowing it to communicate with both parties. This balanced relationship positions India as a potential neutral mediator.
India’s stature on the global stage is rising, and its history of non-alignment and support for peaceful dialogue gives it credibility. However, balancing its strategic partnerships with Israel, Iran, and key Arab states will be challenging.
What are India’s strategic interests in West Asia?
Energy Security: West Asia is crucial for India’s energy needs, supplying about 80% of its oil imports. A wider conflict could disrupt these supplies and increase energy prices, impacting India’s economy significantly.
Economic Ties: India has invested heavily in its relationships with West Asian countries, viewing the region as an extension of its neighborhood. This includes trade partnerships and investments, particularly with major Arab nations and Israel.
Security Concerns: India shares concerns with both Iran and Israel regarding terrorism, particularly threats emanating from Pakistan and Afghanistan. This common ground could facilitate dialogue but also complicates India’s diplomatic balancing act.
How does India’s relationship with regional powers influence its role?
Regional Dynamics: Other regional players such as Qatar, Egypt, Saudi Arabia, and Turkey also influence the situation. Qatar has been active in mediating between conflicting parties, while Egypt’s geographical proximity to Gaza positions it as a key player in ceasefire discussions.
Saudi Arabia’s leadership role in the Islamic world adds another layer of complexity to India’s diplomatic efforts.
Multi-faceted Role: While India maintains strong defense and economic relations with Israel, it also relies on Iran for energy supplies and has historical ties to various Arab nations.
Balancing these relationships is critical for India’s foreign policy strategy.
Way forward:
Diplomatic Engagement and Back-Channel Diplomacy: India can leverage its balanced ties with Israel, Iran, and key Arab states to facilitate back-channel communication, focusing on de-escalation and humanitarian relief.
India’s non-aligned stance and growing global influence position it as a credible facilitator for peaceful dialogue.
Multilateral Approach: India should work through international forums like the United Nations and coordinate with other regional players like Qatar, Egypt, and Saudi Arabia. This multilateral engagement would enhance its role while avoiding the risks of taking sides in the conflict.
Vietnamese President’s recent trip to China seeks to rekindle the historical ties and camaraderie between Mao Zedong and Ho Chi Minh, to strengthen political trust in their bilateral relationship strategically.
Current Diplomatic Relationship between China and Vietnam:
Revived Political Trust: Vietnamese President to Lam’s visit to China sought to revive the historical comradeship between Mao Zedong and Ho Chi Minh.
This visit aimed to strategically strengthen political trust and enhance the comprehensive strategic cooperative partnership between the two communist nations.
Joint Statement on Cooperation: Both countries reaffirmed their commitment to advancing socialism and expressed their desire to build a “Vietnam-China community with a shared future.”
Economic and Strategic Agreements: The visit resulted in 14 agreements covering areas such as connectivity, infrastructure, healthcare, and media.
Trade between the two nations remains robust, with China being Vietnam’s largest import market and a significant investor. Bilateral trade in 2023 reached $171.9 billion.
How do recent events reflect the complexities of Vietnam’s foreign policy towards China?
Bamboo Diplomacy: Vietnam’s foreign policy, known as “Bamboo Diplomacy,” is based on flexibility and resilience.
It aims to maintain strong ties with multiple global powers, including China, while also hedging its bets with the U.S., India, Russia, and Japan to counterbalance Chinese dominance.
Economic Dependence vs. Strategic Hedging: Vietnam’s growing economic interdependence with China, reflected in trade and investment, contrasts with its efforts to hedge against over-reliance by fostering ties with other global players. This balancing act illustrates Vietnam’s pragmatic approach to foreign policy.
Challenges Vietnam Faces in Maintaining Sovereignty Amid Growing Chinese Influence:
Territorial Disputes: The ongoing territorial contestation over the Paracel Islands in the South China Sea poses a significant challenge for Vietnam.
Economic Dependence: While Vietnam benefits from economic ties with China, the growing trade deficit and increased Chinese investments create a dependency that could challenge Vietnam’s autonomy in decision-making, especially in strategic areas like infrastructure and connectivity.
Strategic Hedging and Sovereignty: Vietnam’s efforts to hedge against Chinese influence through partnerships with the U.S., Japan, and India.
Note:Hedging refers to a strategic approach taken by a country to safeguard its interests and security in a complex and uncertain environment.
Way forward:
Enhance Bilateral Engagement: India should deepen its strategic partnership with Vietnam through increased economic cooperation, cultural exchanges, and joint defense initiatives.
Support Regional Multilateralism: India should actively participate in regional forums and initiatives that promote multilateral cooperation, such as the Quad and ASEAN-led dialogues.

British Foreign Minister announced that the deal with Mauritius has settledthe long-standing dispute over the sovereignty of the Chagos Islands, the UK’s last overseas territory in Africa.
The agreement also ensures the long-term future of the Diego Garcia military base, which is jointly operated by the UK and US.
About Chagos Islands (Archipelago)
The Chagos Archipelago is a group of 58 islands located in the Indian Ocean, approximately 500 km south of the Maldives.
It is a strategically significant area, with one of its islands, Diego Garcia, serving as a key military base jointly operated by the UK and US.
The archipelago has been at the centre of a decades-long sovereignty dispute between the UK and Mauritius.
Key Deals and Agreements Related to the Chagos Archipelago
1. British Indian Ocean Territory (BIOT) Formation (1965)
The UK established the BIOT, incorporating the Chagos Archipelago.
The islands were detached from Mauritius before its independence.
Mauritius received a grant of 3 million pounds from the UK as compensation for the detachment.
2. UK-US Agreement on Diego Garcia (1966)
Britain and the US signed a defense agreement, making the BIOT available for joint military purposes.
Diego Garcia became a key military outpost due to its strategic location in the Indian Ocean.
The land for the military base was acquired in 1967, and in 1971, the plantation on Diego Garcia was shut down.
The BIOT administration passed an Immigration Ordinance, which prohibited residents from remaining on the island without a permit. This led to the forced expulsion of around 2,000 Chagossians, many of whom were resettled in Mauritius and the UK.
3. United Nations and International Court of Justice (ICJ) Involvement
2017: The UN General Assembly requested the ICJ to issue an advisory opinion on the legal status of the Chagos Islands.
2019: The ICJ ruled that the UK’s continued administration of the islands was illegal, and the detachment of the islands from Mauritius in 1965 was not done with the free consent of the Chagossians. The UNGA adopted a resolution calling on the UK to withdraw from the Chagos Archipelago within six months.
4. UK-Mauritius Agreement (2023)
After years of dispute, Mauritius and the UK reached an agreement over the sovereignty of the Chagos Islands.
Under this agreement:
The UK has ceded its claims over the islands.
Mauritius is allowed to implement a resettlement program on the islands, excluding Diego Garcia.
The UK retains sovereignty over Diego Garcia, allowing the military base to remain operational for an initial period of 99 years.
A new trust fund is being created for the benefit of Chagossians.
Why did the UK keep Diego Garcia Base?
US-UK Defense Agreement: The base is vital for joint military operations, allowing rapid deployment in critical areas.
Global Operations Hub: Key for US air and naval missions during conflicts like the Gulf War and War in Afghanistan.
Geopolitical Control: Ensures a strong US-UK presence in the Indian Ocean to counteract other powers, especially China.
Strategic Location: Diego Garcia monitors the Malacca Strait and other essential global trade routes, especially energy supplies.

[2013] Discuss the political developments in Maldives in the last two years. Should they be of any cause of concern to India?
At the Albanian-Greek border, Little Prespa Lake is slowly drying.
About Little Prespa Lake
Little Prespa Lake, also known as Small Lake Prespa, is located on the Albanian-Greek border.
The majority of the lake lies in Greek territory, with the southern tip extending into Albania.
The total area of the lake is approximately 450 hectares within Albanian territory, though much of this area has now transformed into swamps or dried up.
It is the smaller part of the nearby Great Prespa Lake, which lies to the south.
Historically, the lake was fed by snowmelt and precipitation, but these have reduced significantly due to climate change and human intervention.
In the 1970s, communist authorities in Albania diverted the Devoll River for agricultural irrigation around the city of Korca.
This diversion significantly reduced the water inflow to the lake, beginning its ecological decline.
Impact of Little Prespa Lake’s Drying
The drying has led to the collapse of the fishing industry, depriving locals of their primary livelihood.
The once-thriving aquatic ecosystem has transformed into a marshland, resulting in biodiversity loss as fish populations vanish.
The diversion of the Devoll River for agricultural purposes has exacerbated the lake’s decline.
The lake could completely disappear if current trends continue, threatening the region’s environmental and economic stability.

Mentor’s Comment: Today’s editorial discusses the limitations and importance of free speech, emphasizing that while individuals have the right to express their opinions without fear of retaliation, this right is not absolute. Key restrictions include defamation, obscenity, and incitement to violence. The article highlights that the government cannot arbitrarily decide what constitutes acceptable speech, as outlined in Article 19(2) of the Constitution. It also notes that free speech serves both instrumental purposes, like fostering better politics, and intrinsic values, such as recognizing individual dignity. However, the government’s attempt to control narratives about its actions can lead to censorship, undermining democratic principles.

Let’s learn!
Why in the News?
Bombay HC ruled against an amendment to the IT Rules, declaring it unconstitutional and upholding free speech rights.
It emphasized that while misinformation is a concern, any regulatory measures must align with constitutional rights, particularly Articles 14 and 19, which protect equality and freedom of speech.
Constitutional Provisions on Free Speech:
• Free speech in our legal system is based on the principle that the state should not decide what expressions are acceptable. •Article 19(2) of the Constitution outlines specific restrictions, such as defamation and national security. • The right to free speech, guaranteed by Article 19(1)(a), is essential for informed political discourse and recognizes citizens’ dignity and autonomy.
What did the IT Rules (2021) say?
Rule 3(1)(b)(v) of the new Information Technology (Intermediary Guidelines and Digital Media Ethics Code) Rules, 2021 imposes strict obligations on internet intermediaries, such as service providers and social media platforms.
If the government’s “Fact Check Unit” labels any reporting about its activities as false, these companies must take steps to avoid hosting that content.
Failing to comply could result in losing their “safe harbor” protection from legal liability under the IT Act, 2000, which safeguards free expression.
Section 79 of the IT Act provides a legal shield for intermediaries (safe harbour), such as social media platforms, by protecting them from liability for content posted by third parties, as long as they take reasonable steps to comply with the law.
Various views presented through the ‘Petition and Response’:
According to thePetitioners’ argument,Rule 3(1)(b)(v) breaches protections for free speech and the State wrongly claims authority to define “fake” information, ignoring less intrusive solutions.
However, the UnionGovernment responded that the law is not coercive and that intermediaries can contest safe harbor losses. While no Constitutional protections are given for false information, regulation of online expression is within government powers.
As per the Judicial opinion, Rule 3(1)(b)(v) is ultra vires, vague, overbroad, and chilling to free speech. Further, the loss of safe harbour does not threaten free expression.
Present Issue over the Intermediaries and Safe Harbour
On Intermediaries: Under Rule 3(1)(b)(v), if the government’s “Fact Check Unit” informs an intermediary that certain information about the government is ‘false’, the intermediary faces a difficult choice: they can either remove the flagged content or defend the user’s right to express their opinion, risking their safe harbour protection in the process.
Here, the intermediaries often prioritize their business interests over the user rights.
They may choose to remove content rather than risk losing their legal protections, effectively sacrificing users’ freedom of expression for their own safety.
On Safe Harbour: Intermediaries can lose the protection under Section 79 of the IT Act if they are aware of illegal activities occurring on their platforms or receive notifications from government agencies about such activities.
Platforms like Facebook, X (formerly Twitter), and WhatsApp serve primarily as hosts for user-generated content.
They do not create this content themselves, which allows them to promote free speech without bearing the same responsibilities as traditional publishers.
Its limitations: True free speech depends on various factors, including access to resources and social dynamics, which can hinder individuals from expressing themselves fully.
Conclusion: While free speech can be reasonably limited, there is no constitutional basis for restricting false or misleading information. The government’s attempt to control narratives about its actions represents censorship and undermines democratic principles, as recognized by the Bombay High Court.
