Science after World War II

Scientific research changed forever in the aftermath of the World War II. Nuclear weapons entered the fray, and scientists worked – not alone anymore – but now in groups rivalling organizations. Governments walked in for the first time, institutionalizing science as a state-project. In the US, Vannevar Bush’s Science: the Endless Frontier advocated for a dichotomy within science, between applied and basic research. India soon advocated for something Though flawed, it’s a blueprint used across the world, including in India. But it needs to change.

Following independence, Jawaharlal Nehru, India’s first prime minister, resorted to building centralized institutions across the country, with the Indian Institute of Technologies (IITs) being famous amongst those pursuing a technical stream. Along with the Indian Institute of Science (IISc.), they’ve attracted the country’s most meritorious and bright students. Nehru viewed and appreciated scientific thinking as a “way of life” and an aspect that’ll break the shackles of superstitious belief in many Indians. He popularized the phrase “scientific temper”, which was later amended into the Indian constitution by his daughter and late prime minister, Indira Gandhi. However, this was during the Emergency Period, when democracy was curtailed, dissidents were imprisoned, and mass sterilization campaigns castrated many men against their will.

Keeping political hypocrisy aside, the administrations since then hasn’t picked up much steam either on being serious about its fundamental scientific research. This is not to say there hasn’t been marvels in technological innovation. Vikram Sarabhai, the technocrat scientist and aristocrat, who helped seed incentives for the country to invest in a space program, envisioned science and technology to enable Indians use of state-of-the-art technology, without going through the rudimentary “stages of growth” that was thought to plague many developing nations. The Indian Space Research Organization (ISRO) builds satellites and rockets, and has been the harbinger rather in public eye for the country’s assertive rise as a space power. Fundamental science research has taken a backseat, with funding woes and political apathy felt even today.

Funding for ISRO virtually trumps anything else that churns in public scientific institutions. Though this is a common attributed share among space faring nations, India’s amongst the lower tier of nations that spends on research and development (R&D) – constituting just 0.64% of the Indian economy, and a continuing decline in funds allocated in yesteryears. India’s next door neighbor China spends some 2.4%, and both the US and UK spend either 3% or more per year.

It’s not like India doesn’t have illustrious or even seminal scientific contributions in the modern age. Scientific research did flourish in British India, amongst a few practitioners, benefitting from uninterrupted time in their laboratories with relatively cheap equipment– as with experimentalists such as Jagdish Chandra Bose and C.V. Raman; to name a few, or theorists including Meghnad Saha and S.N. Bose. Today though, these names remain largely confined to history in public discourse.

Science in pre-independent India

The imperial capital of science in India, Calcutta, was home to top-tier frontier research in quantum mechanics in the early 20th century. In the 1920s, Satyendra Nath Bose, a theorist, solved a particular problem related to the blackbody radiation law that evaded even Einstein. Bose, whom we profiled in our Know the Scientist page, fostered a collaboration with Einstein, culminating in numerous theoretical advances in quantum statistics, especially predicting the fifth state of matter, the Bose-Einstein condensate. Paul Dirac, the English physicist, coined the name bosons, after the class of quantum particles with integer spins, that Bose and Einstein’s statistics describe properties. It was one of these bosons (a word-play on “Bose-ons”) that particle physicists confirmed at the Large Hadron Collider (LHC) in Geneva, Switzerland in 2012.

Science during British India was top-notch, and continued its trend in the immediate aftermath of Indian independence. In 1948, Calcutta was abuzz again, but now with a cyclotron that they were building. A cyclotron’s a device that accelerates particles to near light-speed in the presence of electromagnetic fields, thereby producing radiation. It aided in frontier research in nuclear physics, for example, measuring cross-sections of the uranium nucleus (U-235). Housed at the Saha Institute of Nuclear Physics, accelerator physicists received funding to build a bigger cyclotron at the Variable Energy Cyclotron Centre, touching energies in the MeV range. Today, it’s part of the International Radioactive Ion Beam consortium, helping spread India’s fundamental research reach across the world.

So far, there’s been little coverage about the research in much of central universities and research institutions. It’s surprising how Bose’s contribution to quantum theory found no mention in India’s media discourse. Indian science hasn’t had limelight, not because there’s little research output – though there’s a case to make, as many has made before – but there’s a need for science communicators and journalists to help bridge that gap that exists between scientists and the public. The government has shown little consideration to extend science communication beyond publishing white papers about its importance.

Scientist or engineer?

Media representation of science is confused. The space program, that receives much public adulation and emblematic of national pride, is wrongly perceived as a scientific institution. Space engineers have become scientists in the public eye, despite rocket and satellite development is a matter of engineering, and not science. The former Indian president and “ISRO scientist” Abdul Kalam wasn’t a scientist per se, but an aerospace engineer. Barely mentioned in our public discourse are scientists that’ve done commendable research across the sciences.

Science done in central or local institutions for that matter hasn’t shared the limelight, anywhere as ISRO has since Independence. It’s the government’s pet, and has shaped narratives of technological innovation within and outside India. But this is largely technology history, without much scientific imperative.

Taking initiative

On the flip side, there’s much smaller science projects, that does combine the best of both worlds, combining technology development and science; thus blurring the dichotomy between applied and basic science research.

Govind Swarup, an Indian astronomer, worshiped by his peers as a “father of Indian radio astronomy” had voiced for a radio observatory, the first of its kind in Asia, to be constructed in the 1950s. The Indian government wasn’t interested, unless the astronomers received funds from sponsor countries. Australia had offered to pay and construct, after a long tussle, following which either party withdrew from discussions.

It was not until the 1980s, did India commence building an indigenous radio telescope. In 1995, the country’s first radio telescope, the Great Metrewave Radio Telescope (GMRT) was operational after a decade of construction. The team at GMRT contributed to the first detections of the cosmic gravitational wave background with its European radio astronomy counterparts in the Pulsar Timing Array project.

In 2016, the Indian astronomy community were greenlit to construct a gravitational wave detector in Pune, following confirmation of gravitational waves in February that year. Though this project too bas been plagued by successive delay construction would supposedly take off soon (perhaps late this year). In light of these late developments, politicians and scientists have begun beating the drums about the potential economic impact from involving Indian industry in the construction of the detector – utilizing state-of-the-art quantum technologies – in partnership with international teams. For the scientific community, precious data from the detector is incentive for attracting and inspiring the country’s emerging scientific talent.

Meanwhile, there’ve been hurdles that’ve prevented few other projects from taking off. The India-based Neutrino Observatory (INO), in Tamil Nadu, is one glaring example. Poor policy making amid environmental concerns that wasn’t addressed in time has forestalled construction for more than a decade. In this case rather, neither scientist nor policy maker bothered to engage with the public and hear out their concerns. And it takes much more development in science policies and public engagement to resolve these systemic issues.

India’s EV Investment Story: ₹2.23 Lakh Crore Deployed, But 82% of Capital Needs Still Unmet

India’s electric mobility transition has entered a decisive yet challenging phase. A new analysis from the Institute for Energy Economics and Financial Analysis (IEEFA) reveals a complex narrative: while the country’s EV sector has attracted an impressive Rs 2.23 lakh crore in investments between 2020 and 2025, this represents just 18% of what India must mobilise by 2030 to meet its ambitious clean transport goals.

Unfolding against the backdrop of India’s expanding climate commitments and rising consumer interest in EVs, the report offers a data-rich look into where capital is flowing, where it is missing, and what structural challenges remain hidden beneath headline growth.

A Five-Year Surge in Capital—But Not Enough

Between 2020 and 2025, the EV ecosystem—spanning manufacturing facilities, public subsidies, and charging networks—absorbed Rs 2,23,119 crore in funding. This includes:

  • Manufacturing investments supported primarily through internal accruals
  • Government subsidies, especially through FAME (Faster Adoption and Manufacturing of Hybrid and Electric Vehicles)
  • Charging infrastructure, which remains under-capitalised

Despite this influx, India’s 2030 targets—30% of private cars, 70% of commercial vehicles, 40% of buses, and 80% of two- and three-wheelers going electric—require a total of Rs12.5 lakh crore in investments. That leaves Rs 10.26 lakh crore still unmet.

“While Rs 2.23 lakh crore is a significant capital mobilisation in just five years, it represents only about 18% of the Rs12,50,000 crore required by 2030,” says co-author Subham Shrivastava. “Mobilising the remaining INR10,26,881 crore (USD117.82 billion) by 2030 will require systemic financing reforms.”

The Anatomy of EV Capital

A closer look at the numbers reveals how India’s EV push has been financed so far.

Internal reserves dominate

Manufacturers contributed the bulk of realised investment through their own internal accruals—Rs1,59,701 crore. Debt followed at Rs36,738 crore, while equity accounted for Rs 6,455 crore. But these aggregates obscure important differences across vehicle types.

The three-wheeler segment, driven by a fragmented OEM landscape and low capital-intensity operations, leaned heavily on internal funding and limited debt. Meanwhile, two- and four-wheeler categories showed more diverse capital structures due to the presence of established players and higher investment requirements.

“From 2020–2025, electric three-wheelers attracted the largest share (~78%) of investments among vehicle segments, due to the segment’s maturity and commercial-scale operations alongside its fragmented OEM base,” explains co-author Saurabh Trivedi. “However, recent investment announcements in 2024 and 2025 reveal a pivot towards electric four-wheelers, driven by rising demand for electric cars.”

Charging Infrastructure: A Massive Funding Gap

Perhaps the most critical bottleneck in India’s EV story is the underdeveloped charging ecosystem.

From 2020 to 2025, investments in public charging constituted just 9.6% of the ₹20,600 crore estimated need for 2030. While the country expanded its public chargers from 5,151 to 39,485 over five years, utilisation rates remain low and profitability uncertain.

“Investment in EV charging faces challenges due to limited investor interest, as public EV charging remains an unproven business model, with many charging stations reporting low utilisation rates and high initial costs,” notes co-author Charith Konda.

India’s charger-to-EV ratio continues to lag far behind global benchmarks—a structural weakness that could slow consumer adoption.

The Silent Brake on India’s EV Growth

Beyond infrastructure, the economics of financing EVs present another hurdle.

Commercial EV borrowers currently face interest rates of 15–33%, levels that wipe out the total cost-of-ownership advantage EVs typically offer.

“The binding constraint is not a lack of capital in the system—it is how EV risk is priced,” Shrivastava says. “When lenders remain uncertain about battery performance, residual values, and cash-flow stability, that uncertainty gets reflected in higher interest rates.”

High financing costs disincentivise fleet operators and businesses from transitioning to EVs. As a result, manufacturing capacity cannot scale at the pace needed, creating a demand-supply mismatch.

A New Model for Mobilising Capital

To unlock the remaining ₹10.3 lakh crore needed over the next five years, IEEFA proposes a shift away from subsidy-led growth toward structural risk-sharing.

The solution: a coordinated integrated EV financing platform that consolidates:

  • Partial credit guarantees
  • Residual value protection for batteries
  • Battery-as-a-service (BaaS) arrangements
  • Co-lending structures

This platform would be anchored by development finance institutions with relevant expertise—SIDBI for MSMEs and small commercial fleets, and IIFCL for large commercial deployments.

“Manufacturers need predictable demand signals to scale capacity, but demand depends heavily on affordable credit,” Trivedi adds. “An integrated platform that shares risks appropriately across lenders, OEMs, and public institutions can reduce financing costs and unlock commercial-scale deployment.”

The idea is that as EV adoption grows and asset performance data becomes more robust, lenders will recalibrate risk premiums downward. Over time, underwriting practices could standardise, securitisation markets may emerge, and capital could recycle more efficiently.

A Self-Reinforcing Investment Loop

The report outlines a possible virtuous cycle:

  • Lower financing costs stimulate EV adoption
  • Higher sales volumes create better performance data
  • Improved visibility reduces risk perception
  • Lower risk draws in more capital
  • Manufacturers scale up, benefiting from economies of scale
  • Reduced costs further accelerate adoption

This dynamic, according to IEEFA, is essential for unlocking a mature and self-sustaining EV ecosystem.

A Race Between Ambition and Capital

India’s electric transport ambitions are clear and achievable—but only if the investment framework evolves as rapidly as consumer interest and technological capability.

The core message from the data is unmistakable: India is moving in the right direction, but far too slowly. Recognising this, the authors warn that the next five years will determine the trajectory of India’s EV revolution. The country must transition from policy-driven electrification to a financially self-sustaining ecosystem capable of attracting large volumes of private capital at scale.

The question is no longer about policy commitment but about the cost, structure, and flow of capital in an evolving, high-potential sector.

More Shade for the Rich: Study Exposes Global Urban Heat Inequality

New MIT research shows how wealthier neighbourhoods enjoy more tree shade, exposing global heat inequality and offering solutions for fairer urban cooling.

Wealthier Neighbourhoods Enjoy More Tree Shade, Exposing Global Heat Inequality. New Study Finds

As extreme heat becomes a growing global concern, one of the most effective cooling tools remains remarkably simple: trees. Research has long shown that greater tree coverage in cities helps reduce surface temperatures, improve public health outcomes, and make walking more comfortable in high heat.

Yet a new international study led by researchers at MIT reveals that access to this natural relief is far from equal. Tree cover — and the shade it provides — varies drastically within cities, closely tracking neighborhood wealth.

“Shade is the easiest way to counter warm weather,” said Fabio Duarte, an MIT urban studies scholar and co-author of the study, in a media statement. “Strictly by looking at which areas are shaded, we can tell where rich people and poor people live.”

The research team analyzed sidewalk shade in nine cities across four continents: Amsterdam, Barcelona, Belem, Boston, Hong Kong, Milan, Rio de Janeiro, Stockholm, and Sydney. Despite major differences in climate, wealth, and urban form, every city showed the same trend: affluent areas consistently enjoy more tree-shaded sidewalks.

Duarte noted that this imbalance was striking even in cities globally recognized for greenery. “When we compare the most well-shaded city in our study, Stockholm, with the worst-shaded, Belem in northern Brazil, we still see marked inequality,” he said in a media statement. “Even though the most-shaded parts of Belem are less shaded than the least-shaded parts of Stockholm, shade inequality in Stockholm is greater. Rich people in Stockholm have much better shade provision as pedestrians than we see in poor areas of Stockholm.”

The findings were published in the journal Nature Communications, in a paper titled Global patterns of pedestrian shade inequality. The research team includes scholars from Hong Kong Polytechnic University, the Amsterdam Institute for Advanced Metropolitan Solutions, and members of the MIT Senseable City Lab.

A Global Look at Uneven Shade

To quantify shade, the team used satellite imagery and detailed urban economic data to measure sidewalk coverage on both the summer solstice and the hottest day each year from 1991 to 2020. They assigned each neighbourhood a score between 0 and 1, with higher numbers indicating better shade.

Cities differed sharply in total tree cover — for instance, Stockholm’s neighbourhoods often score above 0.6, while large portions of Rio de Janeiro fall below 0.1. But the inequality within each city was consistent: the wealthiest neighbourhoods always had the greatest shade.

Even in cities known for strong environmental planning, disparities remained. “In rich cities like Amsterdam, even though it’s relatively well-shaded, the disparity is still very high,” said Lukas Beuster, a study co-author. “For us the most surprising point was not that in poor cities and more unequal societies the disparity would be notable — that was expected. What was unexpected was how the disparity still happens and is sometimes more pronounced in rich countries.”

Not all trends were uniform. Some cities, such as Barcelona and Milan, featured lower-income neighborhoods with strong shade coverage. Still, across the global sample, economic status remained a powerful indicator of access to cool, walkable streets.

Why Shade Matters — and What Cities Can Do

Sidewalks became the focal point of the study because they are crucial public spaces used daily by commuters, especially those without access to air conditioning or private vehicles. As cities worldwide face rising temperatures, researchers argue that shade must be treated as essential infrastructure.

“When it comes to those who are not protected by air conditioning, they are also using the city, walking, taking buses, and anybody who takes a bus is walking or biking to or from bus stops,” Duarte explained in a communication from MIT. “They are using sidewalks as the main infrastructure.”

Given the scale of disparity, the researchers suggest one clear strategy: target tree planting along public transit routes, where pedestrian activity is highest and where lower-income residents are most likely to walk.

“In each city, from Sydney to Rio to Amsterdam, there are people who, regardless of the weather, need to walk,” Duarte said . “Therefore, link a tree-planting scheme to a public transportation network. … If you follow transit, you will have the right shading.”

Beuster added that cities should think of urban trees as functional assets, not just aesthetic ones, emphasizing their central role in cooling and public health.

Duarte further stressed the importance of prioritizing shade where people actually move through the city. “It’s not just about planting trees,” he said in a media statement. “It’s about providing shade by planting trees. If you remove a tree that’s providing shade in a pedestrian area and you plant two other trees in a park, you are still removing part of the public function of the tree.”

“With increasing temperatures, providing shade is an essential public amenity,” he added in a media statement. “Along with providing transportation, I think providing shade in pedestrian spaces should almost be a public right.”

Global energy leaders convened in Paris this week for the International Energy Agency’s Ministerial Meeting, underscoring the agency’s expanding role in shaping international cooperation at a time of rising demand, geopolitical tensions, and accelerating energy transitions.

The two-day gathering drew senior government representatives from a record 54 countries, around 40 of them at ministerial level. Executives from 55 companies — representing a combined market capitalisation of $14 trillion — joined leaders of intergovernmental organisations in what became the largest Ministerial Meeting in the agency’s history.

At the heart of the discussions was a clear message: energy security, affordability and sustainability can no longer be pursued in isolation. They require deeper multilateral coordination, stronger data systems, and expanded institutional alliances.

Expanding the IEA Family

Member governments unanimously agreed to move forward on strengthening institutional ties with Brazil, Colombia, India and Viet Nam. In a major step, Colombia was invited to become the IEA’s 33rd Member. Brazil was invited to begin the process toward full membership following a request from its government. Ministers also welcomed recent progress in discussions with India regarding its request for full membership. Viet Nam joined as the newest Association country in the IEA Family.

The expansion significantly alters the geometry of global energy governance. With these additions, the IEA Family’s share of global energy consumption now exceeds 80%, up from less than 40% a decade ago — reflecting a profound shift in the agency’s global reach.

“This Ministerial Meeting, our largest ever, affirmed the immense value of the IEA at a moment when global energy demand is rising and the challenges facing the energy system are intensifying. In this context, our wide range of objective data and analysis is more important than ever,” said IEA Executive Director Fatih Birol.

“In a strong step forward for global energy governance, key countries such as Brazil, Colombia, India and Viet Nam are strengthening their ties with the IEA. This puts the IEA Family’s share of global energy use at more than 80%, up from less than 40% ten years ago. With major energy issues high on the international agenda, we stand ready to support governments with the insights they need to plan for the future, helping leaders deliver on their goals of ensuring greater energy security, affordability and sustainability.”

Deputy Prime Minister Sophie Hermans of the Netherlands, who chaired the Ministerial, framed the discussions in terms of resilience amid uncertainty.

“These two days in Paris have reaffirmed how essential energy is to our daily lives – it is the invisible driving force behind everything we do. Under the umbrella of knowledge of the International Energy Agency, we have once again seen that international cooperation is key,” she said. “Our priority is clear: secure, affordable and sustainable energy – and resilient systems that can endure in an uncertain world.”

In a video address opening the meeting, French President Emmanuel Macron emphasised the IEA’s analytical leadership. “Through its in-depth analyses, and the technical expertise of its team, the IEA, under the leadership of its Executive Director Fatih Birol, plays an essential role. It enlightens us to help us guarantee our energy security and steer the energy transition.”

Beyond institutional expansion, the Ministerial marked a strong endorsement of deeper cooperation on critical minerals — increasingly viewed as the backbone of clean energy technologies.

In a special declaration, Ministers backed expanding collaboration under the IEA Critical Minerals Security Programme to address mounting risks to global supply chains. They called for strengthened data tools, collaborative exercises and clearer guidance on measures such as stockpiling, aimed at diversifying supply chains and building resilience against supply shocks.

Clean Cooking and Energy Access

Member countries also approved the integration of the Clean Cooking Alliance into the IEA, positioning the agency as the principal multilateral forum for advancing clean cooking solutions. The move seeks to accelerate access for the more than two billion people worldwide who still lack clean cooking technologies.

The integration comes ahead of the IEA’s second Summit on Clean Cooking in Africa, scheduled for July 2026 in Nairobi, where governments and industry leaders are expected to review progress since the inaugural 2024 summit and outline new financing and policy pathways.

Energy Security in the Age of Electricity

Two high-level dialogues during the Ministerial focused on safeguarding energy security in what officials termed the “Age of Electricity,” and on supporting Ukraine’s energy system amid ongoing disruptions. Ukrainian First Deputy Prime Minister and Minister of Energy Denys Shmyhal participated in discussions on rebuilding and securing Ukraine’s energy infrastructure.

As energy demand continues to climb and transition pathways grow more complex, the IEA’s expanding membership and programme scope suggest that multilateral coordination — once largely confined to oil security — is now being repositioned as the backbone of a rapidly electrifying and mineral-intensive global energy system.
