1 . Break the Chain: India Must Focus on Cutting Transmission of Leprosy
India has reduced the prevalence of leprosy and grade-2 disability, but continued transmission remains a concern. Prevalence had fallen below 1 case per 10,000 population by 2005, leading to WHO’s declaration of leprosy as a “public health problem” eliminated. However, transmission began rising again in the early 2010s. The priority now is therefore to cut transmission, in line with the National Strategic Plan (NSP) and Roadmap for Leprosy 2023–27.
Key Concerns and Way Forward
- Child transmission: India accounted for around 46% of all child leprosy cases reported worldwide in 2025, highlighting the need for stronger child-focused detection and prevention.
- Concentrated burden: Chhattisgarh, Jharkhand, Odisha and Maharashtra account for a disproportionate share of the national burden.
- Slow progress: Against the projection of 300 districts achieving “interruption of transmission”, only 148 districts had achieved it in 2025–26.
- Detection and prevention: More than 70 crore people were screened in highly endemic areas in 2025–26, with 24,367 cases detected through screening; ASHA workers also identified suspected cases, of which 48,027 were confirmed.
- Surveillance and diagnosis: India has operationalised digital surveillance and is considering the MPV vaccine for highly infectious patients. Persistent lacunæ in case detection, late diagnosis and misdiagnosis as ordinary skin conditions continue to sustain transmission.
- Targets need recalibration: The 2025-26 report overshot projections for overall incidence by 41%, childhood incidence by 6% and grade-2 disability by 34%. India therefore needs to strengthen efforts in locations and social settings where diagnosis and transmission remain entrenched, rather than easing efforts after meeting prevalence-based targets.
The focus should move from simply reducing prevalence to actually interrupting transmission, with prevalence becoming a secondary outcome.
2. Let There Be Light: The Nobel Laureates for Medicine Illuminated How the Brain Works
The 2026 Nobel Prize in Physiology or Medicine was awarded to Karl Deisseroth, Peter Hegemann and Georg Nagel for discoveries concerning light-gated ion channels and optogenetics. Hegemann’s work on Chlamydomonas showed how a light-sensitive algal protein could open a channel and allow charged ions to flow into cells, while Nagel helped establish the role of the blue-light-sensitive protein. Deisseroth transformed this into a light-controlled switch for nerve cells, making it possible to study how specific neural circuits regulate memory, emotions and behaviour.
Optogenetics uses harmless viral agents to deliver genes for light-sensitive proteins into specific target cells, after which precise pulses of light can activate selected neural pathways. This has enabled researchers to map neural circuits in ways that were previously difficult or impossible and has provided the groundwork for clinical treatments targeting neurological and psychiatric conditions, including Alzheimer’s disease and addiction. Researchers are also exploring its use in restoring sight.
The work also demonstrates how fundamental scientific discoveries can move towards practical therapies, diagnostics and healthcare applications. At the same time, the benefits of such advances need to reach people irrespective of their location or station in life, making equitable access an important part of translating scientific progress into better health outcomes.
3. Indian Research Can Shape the World
India’s technological challenge is not simply to catch up with advanced countries, as dependence on external licences and know-how can become a burden. The experience of Indian research contributing to CRISPR technology shows that investment in fundamental research can move from curiosity to application and create technologies with global impact.
What India Needs to Change?
- Invest in high-quality research: Build strong fundamental research capabilities and connect them more effectively with practical applications.
- Open national laboratories: National labs should become more accessible to researchers, students and companies outside their walls, enabling greater interaction with universities and industry.
- Create research “foundries”: Experimental spaces in engineering, physics, biology, chemistry and mathematics can allow young researchers to work with real instruments on real problems.
- Reduce regulatory burden: High-quality institutions that already comply with regulations should not face excessive General Financial Rules compliance. Accountability should be measured by outcomes rather than procedure at every step.
- Speed up approvals: Research involving biological materials and clinical trials faces slow and unpredictable approvals. Reducing these hurdles is particularly important for small and medium-sized institutions that cannot afford prolonged delays and costs.
The central shift is therefore from “catching up” to building the capacity to create. India already has high-quality research institutions and scientific talent; the priority is to make these pockets of excellence the norm and translate scientific capability into globally relevant technologies.
4. Why Growing Trust in Digital Payments May Be Leaving Indians More Exposed to Cybercrime
UPI has become one of India’s most trusted and frequently used payment modes, but the SPIR 2026 findings reveal a trust paradox: people who trust online banking the most and use UPI most frequently are also more likely to have experienced cybercrime. UPI processed over 24,000 crore transactions in FY 2025-26, worth around ₹314 lakh crore, making its scale—and therefore the potential cybercrime surface—enormous.
The Trust–Vulnerability Paradox
- UPI dominance: Around 70% of India’s internet-connected population uses UPI. Nearly 49% of respondents use UPI every day, while another 24% use it once or twice a week.
- Frequency of use: UPI is used “many times” by 48%, compared with 20% for debit/credit cards, 14% for payment wallets and 7% for NEFT/RTGS.
- High perceived safety: Around **23% of respondents considered online banking modes “very safe” and about 40% “somewhat safe.” Among highly vulnerable users, however, the figures were much higher — 49% considered them “very safe” and 39% “somewhat safe.”
- Victimisation rises with trust: Among those who considered online banking “very safe”, 28% had been victims of cybercrime, compared with only 14% among those who never used online banking. UPI users were also more likely to have experienced cybercrime than those who never used it.
- Behavioural vulnerability: High trust can coexist with unsafe practices—such as opening unverified links, files or OTPs from unknown callers—creating opportunities for fraudsters.
How the Cybercrime Ecosystem Exploits Trust?
- Cybercrime increasingly operates through a supply chain, with fraudsters using pre-activated SIM cards, bank accounts and cell phones to receive and move stolen money.
- A relatively small investment in such “kits” can enable fraudsters to swindle large amounts, while making the transactions difficult to trace.
- Fraudsters also recruit users as intermediaries, leaving them exposed to police action while the actual perpetrators remain difficult to identify.
- The deception can continue after the initial fraud: victims may be persuaded to share personal information or even hand over their bank accounts after being manipulated into believing they were unknowingly involved in a crime.
The central concern is therefore not a lack of trust in digital payments, but excessive trust without corresponding cyber-awareness.

1 . G7 to Release 100 mn Barrels of Crude Oil, Oil Products: Will This Curb Diesel Prices?
The G7 has agreed on a coordinated release of around 100 million barrels of crude oil and petroleum products from emergency reserves to ease pressure on global fuel markets. The move comes amid a wider global supply crunch and soaring fuel prices, with diesel demand remaining strong across transport, agriculture, construction and other industries. However, the release may provide only temporary relief if the underlying supply disruptions persist.
Why Diesel Prices Are Rising and Will the Release Help?
- Supply disruption: Diesel prices have risen sharply amid tighter global oil markets and reduced supply.
- Geopolitical pressures: The G7 move comes against the backdrop of geopolitical crises and supply disruptions, with Europe particularly affected by reduced diesel imports from Russia and the Middle East.
- G7 intervention: The release of 100 million barrels from emergency reserves is intended to increase supply and ease pressure on fuel prices. Countries will also examine additional diesel releases if required.
- Limited impact on prices: The measure can provide short-term relief, but the article notes that its effectiveness depends on how quickly the additional supply reaches markets and whether the broader global supply crunch
- Diesel export ban: The US has not banned diesel exports. Such a move could have reduced global supply further, but the US has continued to export diesel even as domestic prices have risen.
Impact on India
- Import dependence: India’s high crude-oil import dependence makes it vulnerable to global oil-price shocks, which can transmit into domestic diesel and other fuel prices.
- Industrial impact: Higher diesel prices raise costs for transport, agriculture, construction and other industries, potentially increasing the cost of production and distribution.
- Inflationary pressure: Expensive diesel can feed into the prices of goods and services through higher transportation and logistics costs.
- Retail consumers: Consumers may face higher costs where diesel is used directly, while public-sector fuel prices may also be affected.
- Trade-off: The G7 release may soften global prices temporarily, but sustained relief for India will depend on the duration of the supply disruption, global oil availability and international diesel prices.
2. Through ‘Ghost Particles’ in Ice, Window to Universe
The 2026 Nobel Prize in Physics recognised Francis Halzen for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin. Neutrinos are electrically neutral subatomic particles produced in a wide range of nuclear and particle interactions. High-energy astrophysical neutrinos originate in extremely energetic cosmic environments and can travel vast distances without being deflected by magnetic fields.
Neutrinos and the IceCube Observatory
- “Ghost particles”: Neutrinos are extraordinarily difficult to detect because they rarely interact with matter. Trillions of neutrinos pass through Earth every second, with most passing through matter undetected.
- Why they are scientifically valuable: Since neutrinos are not deflected by magnetic fields, their direction can retain information about their astrophysical sources, unlike many charged cosmic particles.
- IceCube: Located at the Amundsen-Scott South Pole Station in Antarctica, IceCube uses the Antarctic ice as a giant detector. It became operational in 2011.
- How detection works: Thousands of light-sensitive detectors are embedded deep in the ice. When a neutrino interacts with matter, it can produce a charged particle that travels through the ice and generates a faint flash of light. IceCube detects these flashes and reconstructs the neutrino’s direction and energy.
- Why Antarctica: The enormous volume of clear, deep Antarctic ice provides a suitable medium for detecting the extremely rare interactions of neutrinos.
From Neutrino Detection to a New View of the Universe
The significance of IceCube goes beyond detecting neutrinos. High-energy astrophysical neutrinos can travel from distant cosmic sources and carry information about energetic processes that cannot be studied adequately through conventional electromagnetic observations. Their detection has therefore opened a new field of neutrino astronomy and provided scientists with another way of studying the cosmos.
IceCube has detected extremely high-energy neutrinos and helped scientists investigate their possible astrophysical origins. The work demonstrates how neutrinos can act as messengers from the distant universe, revealing phenomena that may otherwise remain hidden. Thus, the Nobel-recognised work transformed Antarctic ice into a giant scientific observatory and established neutrino detection as a new window into the universe.
3. A War in Iran, an Election in America, and the Blurred Lines Between Politics and Conflict
Iran’s Islamic Revolutionary Guard Corps (IRGC) is attempting to influence the American political debate by appealing directly to U.S. voters. Its 25-page letter urges Americans to reject Trump’s policies and consider “peaceful coexistence” with Iran, arguing that military and economic pressure could force the Islamic Republic to fall. With the U.S. midterm elections approaching, the economic and political consequences of the Iran conflict are becoming increasingly difficult to separate from the military campaign.
Iran–US Conflict Enters the Political Arena
- IRGC’s appeal: While retaining its “Death to America” slogan, the IRGC claims it has no quarrel with ordinary Americans and makes Trump the immediate political target.
- Electoral calculation: The appeal appears aimed at using the war’s economic and political costs to influence American public opinion and debate over Iran policy.
- Historical precedent: Iran’s 1979 Revolution and hostage crisis became intertwined with the 1980 U.S. presidential election, contributing to the political difficulties faced by Jimmy Carter.
- Trump’s calculation: Trump maintains that the midterms will not determine his Iran policy, but his comments about the war potentially being won “right after the election” give the military campaign an unmistakable political dimension.
- New front of conflict: Both sides increasingly view the other’s domestic political contest as another front, alongside the conventional battlefield.
Oil, Hormuz and Economic Pressure
- Strait of Hormuz: Gulf crude exports averaged about 3 million barrels a day in September, roughly 91% of pre-war levels, as oil flows through the Strait have accelerated.
- Oil ≠ cheaper fuel: More crude moving through Hormuz does not automatically mean cheaper diesel in the U.S.; crude must still be transported, refined and distributed.
- Fuel-price politics: Diesel prices directly affect transportation and cost of living, making energy prices an important domestic political issue in the U.S.
- G7 intervention: The G7’s decision to release 100 million barrels of crude and fuel products from emergency reserves aims to ease market pressure, but sustained escalation could push prices higher again.
- US economic pressure: “Operation Economic Outcast” has expanded sanctions to Iran’s automotive, rail, manufacturing and steel sectors, while foreign financial institutions have been warned about sanctions for doing business with Iran.
- Iran’s leverage: Tehran seeks to exploit the relationship between military escalation, oil prices and American public opinion, while the U.S. uses sanctions and economic pressure to constrain Iran.
Larger Lesson: Domestic Politics as a Strategic Front
- The conflict demonstrates how war, elections, fuel prices, sanctions and public opinion can become interconnected.
- Iran is attempting to turn the economic costs of war into political pressure on Trump, while Washington combines military and economic pressure against Tehran.
- The distinction between the battlefield and the political arena is therefore becoming increasingly blurred.
- For democracies such as India, the broader lesson is that political differences are inevitable, but excessive domestic polarisation can weaken a country’s ability to respond to external challenges and interference.
- Effective foreign-policy engagement therefore also requires managing political differences at home, so that domestic conflict does not undermine national capacity to deal with a turbulent external environment.
4. Higher Yields in US Test India’s Macro Resilience
Rising 10-year U.S. Treasury yields above 5% and a narrowing India-US yield spread are testing India’s ability to absorb global financial volatility. However, stronger domestic fundamentals provide some resilience.
External Pressures
- Higher-for-longer rates: Elevated U.S. yields raise global borrowing costs and reflect concerns over U.S. fiscal and debt sustainability.
- India-US yield spread: The spread has narrowed to around 200 basis points, increasing pressure on Indian yields, capital flows and the rupee.
- Crude risk: The US-Iran conflict could push Brent higher, raising imported inflation and weakening the rupee. When Brent approached $98/barrel, India’s 10-year yield moved towards 7%.
- Other risk: A possible AI bubble burst could add to global financial volatility.
Why India Has Some Resilience?
- Strong fundamentals: Fiscal deficit is moving towards 4% of GDP, inflation is within the target band, the current account is stable and forex reserves remain ample.
- Domestic capital: Rising retail and domestic institutional participation has strengthened the domestic capital base and reduced dependence on foreign investors.
- Borrowing costs: Higher global yields can raise borrowing costs for both Centre and States; recent State Development Loan auctions have seen yields around 9%.
- Overall: India has greater capacity to withstand global volatility, but higher-for-longer U.S. yields, crude-price shocks and tighter financial conditions require close monitoring as policy space to absorb further shocks is limited.
