Many children today transition from playfulness and innocence to mental stress and other worries during adolescence. It is crucial to understand children’s issues and actively seek solutions rather than fretting over them. These challenges during a critical stage of development can significantly impact children’s memory and intelligence.

A world full of happiness and no worries… Such is the view of parents and guardians about the world of children. They don’t have to worry about work to be done or responsibilities, so what’s the stress on them? But the data coming out about children’s mental health suggests that these are all just our misconceptions.

The number of children seeking counseling and mental health treatment is increasing day by day. To those who wonder what tension they have for this alone, they say, many. At a very young age, children experience minor stress or mental tension!

What is stress?

What is stress if it affects even children? Stress is the body’s coping mechanism to deal with and adapt to challenging situations. A balance of demands from multiple sources or the ability to meet them leads to stress. Such demands may come from family, work, school, or friends, and sometimes one’s own demands can also lead to stress. Stress occurs when the demand and the ability to meet it do not match.

Dr Rashmi Prakash, a member of the Australian Psychological Society, says that a small amount of stress is beneficial to children. But stress can have long-term effects on children if it goes too far

Stress occurs in children for many reasons. The worry of missing parents at a very young age, academic issues later in life, social pressures, mental and physical abuse, problems between parents and isolation all contribute to stress in children. Dr Rashmi Prakash, a member of the Australian Psychological Society, says that a small amount of stress is beneficial to children. But stress can have long-term effects on children if it goes too far. Recently Indian researchers have found that childhood stress can affect memory skill of students.

Research conducted by a team consisting of Radha Raghuraman, Anoop Manakadan, Gal Richer Levin, and Sreedharan Sajikumar, in 2022, found that childhood stress can have a detrimental effect on memory.

How to spot stress in children

Stress and related problems in children can be difficult to identify, but sudden anger, mood swings, misbehaviour, changes in sleep patterns, and bedwetting can all be considered signs of stress. Some may also experience physical effects due to stress. For example, stomach ache and headache. Others have symptoms such as lack of concentration and inability to complete studies. Apart from this, being away from everyone and spending a lot of time alone is a sign of stress. Signs of stress include thumb-slapping, hair-twisting, nose-picking in young children, and lying, bullying, and backbiting in adults. Stressed out children can get into big fights even over small things. Falling behind in studies is also a symptom of stress.

The connection between stress and memory

Experts say that children are more stressed than adults. This is due to constantly having to face new and confusing situations. Children are greatly influenced by the expectations placed on them by the adults around them, especially parents and teachers. Children often judge themselves by those expectations. When those expectations are not met or when their skills, abilities, and pride are called into question, they are unable to cope.

Separation from parents especially mother, physical or mental abuse, fear etc. can lead children of any age to stress

Recent studies have shown that stress levels in children have been on the rise over the past few decades. Radha Raghuraman says that exposure to stress during childhood can affect the ability to connect different types of memories as adults. The research team conducted studies on this in mice. As the juvenile phase in mice is equivalent to the adolescent phase in humans, adolescent stress is the main concern here. Radha explains that since the structures of the memory-related brain regions of mice and humans are almost identical, their findings may hold true for humans as well.

Separation from parents especially mother, physical or mental abuse, fear etc. can lead children of any age to stress. Depending on the age at which stress occurs, how long it has lasted, the intensity, and the type of stress, the changes it causes in the body and behaviour will vary.

Adolescent stress stimulates certain epigenetic factors. Like a gene, a piece of DNA that carries information necessary for specific functions in a cell, an epi-gene is a factor that causes a gene to decide whether or not to express the information in the gene, and if so, how much to express.

Parental proximity also plays a major role in reducing stress in adolescents. Even after work, you should be interested in sitting with the children and asking about their affairs.

Through their study, Radha and his team found that stress during adolescence results in increased activation of the epi-gene G9a/GLP. It affects the formation of certain proteins that stabilise newly formed memories. As a result, memories that have already been formed are perfected and as they grow, there is no room for other memories that come in connection with them. Associative memory is the ability to connect existing memories with recent or recent events and find similarities and dissimilarities between them. Adolescent stress mainly affects associative memory. Radha says that G9a/GLP was found to be significantly higher in stressed mice. The researchers also found that associative memory was restored when G9a/GLP was blocked with the drug.

How to save children from stress

Adequate rest, nutritious food, closeness, attention and care of parents can give children a lot of relief from stress. Parents should try to be with their children when they want. If you notice that there are any problems, talk to them openly instead of thinking that they will tell you here.

Parental proximity also plays a major role in reducing stress in adolescents. Even after work, you should be interested in sitting with the children and asking about their affairs.

Studies remind us that stress during adolescence should be viewed more cautiously than stress at any other time. Adolescence is also a period of growth in children. Facing stress at a time when the development of many important organs including the brain is not complete can lead to many types of consequences while growing up.

How the Iran–Israel–US Conflict Ripples Through India’s Economy and Energy Future

The immediate reality is uncertainty: higher freight, rising insurance, volatile crude, jittery exporters

The tremors began far from India’s shores. US and Israeli strikes on Iran, followed by retaliatory actions, have redrawn fault lines across West Asia. But in New Delhi, in oil refineries along the western coast, and in rice mandis across Haryana and Punjab, the aftershocks are already being felt.

“US and Israel attacks on Iran, and subsequent counter attacks have exposed a new wave of geopolitical risks,” notes a policy briefing from Climate Trends, reviewed by EdPublica. For India — bound to Israel by strategic ties and to Iran by history and geography — the moment is fraught with complexity.

At the heart of the unfolding crisis lies a narrow maritime artery: the Strait of Hormuz.

The Strait of Hormuz: India’s Energy Lifeline

Nearly a quarter of the world’s crude oil flows through the Strait of Hormuz — a chokepoint linking West Asian producers to global markets. For South Asia, the dependency is sharper. Around 40% of the total crude oil consumption of India, China, Japan and South Korea transits this passage.

India imports nearly 90% of its crude oil. Of its daily imports, 2.5–2.7 million barrels per day — largely from Kuwait, Saudi Arabia, Iraq and the UAE — pass through these contested waters.

The risks are no longer theoretical. According to reports, Iran has been relaying warnings over VHF radio to ships, cautioning that passage may not be guaranteed. Insurance pricing for shipping has risen by 50% overnight. Freight rates are climbing. The Director General of Shipping has issued a circular advising stakeholders not to deploy Indian crews in Iran.

If Iran’s 3.3 million barrels per day production is disrupted, oil prices could rise 9–15%, pushing crude from a base of $70 per barrel to roughly $76–81.

For India, the impact would be “more price driven and not volume driven”. Yet price shocks ripple quickly — widening the current account deficit, weakening the rupee and feeding domestic inflation.

Vivek Y. Kelkar, researcher working at the intersection of geo-economics and sustainability, warns: “Much depends on how long the conflict endures and whether risks to the Persian Gulf and the Strait of Hormuz persist… For India, the impact would be indirect but significant. With nearly 90 percent import dependence, every $10 per barrel rise increases the annual import bill by about $13–14 billion, widening the current account deficit, pressuring the rupee and adding to inflation.”

He adds that China — which buys roughly 90% of Iran’s crude exports — could pivot more aggressively toward Russian, Iraqi, Saudi and West African grades if Iranian volumes shrink. “If Beijing pivots toward the same Russian or Atlantic Basin supplies that India relies on for diversification, India’s energy security could become more expensive and more contested. The likely outcome is not deep scarcity, but tighter global balances, higher prices and diminished negotiating leverage for Indian refiners.”

From Oil Tanks to Rice Fields

The consequences extend well beyond petrol pumps.

In the weeks before the conflict escalated, Iranian importers had placed large orders for basmati rice, pushing local prices up by about ₹10 per kg. Iran accounts for roughly 25% of India’s basmati exports; Iraq another 20%. Together, that’s over 2 million tonnes valued at more than $2 billion annually.

Uncertainty now looms over these trade flows. Tea exports too may take a hit — nearly ₹7 billion worth was exported to Iran in 2024–25.

More broadly, Middle Eastern countries including Iran, Bahrain, Kuwait, Qatar and the UAE account for bilateral trade worth about $117.32 billion, with the UAE alone contributing nearly $100 billion. Any regional escalation directly threatens these ties.

The UAE Factor: A Stable Hub Under Strain

Dubai has long been viewed as West Asia’s insulated commercial gateway — a financial and logistics hub even when politics elsewhere burned. But the conflict “fundamentally alters Dubai’s longstanding reputation as a politically insulated financial and trade hub”. India and the UAE have been expanding cooperation in renewables, green hydrogen and critical minerals. The India–UAE Comprehensive Economic Partnership Agreement (CEPA), signed in 2022, marked India’s first such accord in the MENA region. Escalation now risks slowing joint ventures and technology exchanges just as clean transition investments were gathering pace.

“India’s policy of strategic autonomy has so far helped it navigate the choppy waters of geopolitics but the balancing act has become increasingly tough. The conflict in west Asia and its repercussions raise the risks to its supply chains, test energy security and increase insurance costs and fuel inflation if energy prices remain elevated, as is expected if the Strait of Hormuz is blocked… Yet, despite the rising risks India’s economy and markets are relatively better placed to ride this geopolitical storm,” Archana Chaudhary, Associate Director at Climate Trends, notes.

A Clean Energy Imperative, Not Just a Climate Goal

The crisis may also sharpen India’s clean energy calculus. Elevated oil costs increase dollar demand, typically putting downward pressure on the rupee. Costlier fuel filters into transportation, logistics and eventually food prices. Renewable energy supply chains — including critical minerals — could also be disrupted, as significant shipping traffic flows through Hormuz

Yet analysts see opportunity in the turbulence. “The recent strikes only reinforce the validity of India’s long-standing principle of strategic autonomy. In an increasingly volatile West Asian landscape, the wisdom of accelerating our clean energy ambitions becomes even more apparent for energy security. Reducing dependence on imported conventional energy sources, i.e. oil and gas, through rapid deployment of clean technologies is no longer just a climate imperative but a strategic necessity… In this fractured geopolitical order, India must deepen the momentum toward clean energy transition and technological self-reliance to insulate its growth trajectory from external shocks,” Aarti Khosla, Director, Climate Trends, argues.

Vaibhav Chaturvedi, Senior Fellow at CEEW, echoes the urgency: “The US-Iran war doesn’t bode well for the global energy economy. In the short run, we can expect an increase in oil prices. In the medium term, if the war drags, there would be a negative impact on the global economy. The event will undoubtedly create headwinds for India’s economy. India will do well to leverage its relationships to access cheaper oil in this scenario. This is a moment to bring investments to ramp up plans to scale up electrification of the power and transport sector faster as the ultimate solution to energy security.”

Duttatreya Das, Energy Analyst–Asia at Ember, calls this a turning point: “The past few months have been challenging for India’s crude supplies—first the shift away from discounted Russian Urals to avoid U.S. tariffs, and now the potential volume impact from disruptions in West Asia. While these disruptions may be short-term, India cannot simply afford to remain hostage to geopolitical volatility… Moments like these offer an opportunity to recalibrate its mobility policy, through electrification and a faster expansion of ethanol blending in the near term.”

A Moment of Strategic Testing

In South Block, a Cabinet meeting chaired by the Prime Minister signals the seriousness of the moment. OPEC has indicated it may adjust production to maintain market stability. India’s long-held doctrine of strategic autonomy — balancing relationships across rival blocs — is now under stress. After US pressure restricted purchases of Russian oil, India diversified more toward Gulf suppliers, inadvertently deepening its exposure to Hormuz-linked risks. Though it imports from over 40 countries, geography and geopolitics cannot be entirely diversified away.

The immediate reality is uncertainty: higher freight, rising insurance, volatile crude, jittery exporters.

The longer-term question is whether this crisis accelerates a structural pivot. In the shadows of tankers and warships, India’s energy transition debate is no longer abstract. It is entangled with inflation, trade, currency stability and food security.

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

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

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.”
