How childhood stress can undermine memory skills
Experts say that children are more stressed than adults. This is due to constantly having to face new and confusing situations. Researchers have found that childhood stress can affect memory skill of students.
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 China Is Redrawing the Global Map of Critical Minerals
China’s $120bn critical minerals investment is reshaping global supply chains and strengthening its dominance in the clean energy economy.
China’s $120 billion investment surge into critical minerals is not just about securing resources—it is about shaping the architecture of the global clean energy economy. As supply chains realign, the balance of industrial power is shifting in ways that could define the next century
The global energy transition is often framed as a technological race—who will build the best batteries, the most efficient solar panels, or the most advanced electric vehicles. But beneath this narrative lies a more fundamental contest: control over the raw materials that make these technologies possible.
Lithium, cobalt, nickel, rare earths—these are not just commodities. They are the building blocks of the new industrial economy.
Over the past few years, China has moved decisively to secure them.
A recent analysis by Climate Energy Finance (CEF) estimates that China has committed more than $120 billion in outbound investment into critical minerals and metals since 2023, spanning multiple continents and resource categories.
What this report documents is not merely investment flows, but the architecture of a new global green industrial order,” says Tim Buckley, report lead author and Director at CEF.
This is not a scattered set of deals. It is a coordinated strategy—one that is rapidly reshaping the global resource landscape.
Beyond Extraction: Building a System
Historically, global resource investment followed a familiar pattern: capital flowed from developed economies into resource-rich regions, extracting raw materials for export with limited local value creation.
China’s current approach marks a significant departure.
Instead of focusing solely on extraction, Chinese firms are increasingly investing in processing, infrastructure, and industrial ecosystems within host countries—building ports, railways, clean energy systems, and enabling manufacturing capacity.
As Associate Professor of the Australia–China Relations Institute at the University of Technology, Marina Yue Zhang notes, the strategy has moved “well beyond simple resource extraction towards a more integrated model linking resource acquisition with processing, infrastructure, manufacturing, and long-term industrial partnerships.”
The result is a vertically integrated system that connects resource acquisition, refining, and industrial production into a single coordinated framework.
China already dominates many parts of this chain—accounting for roughly 90% of global rare earth refining, over 70% of cobalt processing, and around 60% of lithium processing.
The Logic of Vertical Integration
At the heart of China’s strategy is a simple economic insight: control the entire value chain, and you control the market.
By investing simultaneously in mines, processing facilities, and downstream manufacturing, China reduces its dependence on external suppliers while increasing global reliance on its capabilities.
Buckley underscores the scale and intent of this approach: China has built “a vertically integrated green supply chain spanning every continent, combining state-directed capital with private enterprise execution at a speed and scale no competitor country comes close to matching.”
For competitors, replicating this model is not just a matter of capital—it requires alignment between policy, industry, and long-term planning.
A New Partnership Model in the Global South
One of the most significant shifts in China’s strategy is how it engages with resource-rich nations.
Earlier models of foreign investment were often criticised as extractive. Today, Chinese firms are increasingly offering in-country processing, infrastructure investment, skilled employment, and technology transfer in exchange for long-term resource access.
As CEF analyst Matt Pollard explains, these are “not just mining deals, but blueprints for green industrialisation,” offering pathways for emerging economies to build domestic industries.
For many countries in the Global South, this represents a significant opportunity—but also a strategic choice.
A Multipolar Shift
China’s resource strategy is unfolding in a rapidly changing geopolitical landscape.
As Western economies adopt more protectionist measures and retreat from multilateral engagement, China has expanded its global investment footprint—particularly across emerging markets.
Buckley argues that this divergence is accelerating China’s momentum: its trajectory is “one of adaptation and acceleration, not retreat,” even amid rising geopolitical tensions.
The result is a shift toward a more multipolar global economy, where influence is distributed across multiple centres rather than concentrated in traditional Western powers.
Supply Chain Risks and Strategic Vulnerabilities
China’s growing dominance also raises concerns.
The concentration of extraction and processing capacity creates risks for global supply chains, energy security, and industrial competitiveness.
Countries dependent on these supply chains face potential vulnerabilities—from geopolitical disruptions to market imbalances.
Efforts to diversify supply are emerging, including strategic collaborations such as Japan’s partnership with Australia’s Lynas Rare Earths to secure long-term supply.
But scaling such alternatives remains a complex and time-intensive challenge.
The Limits of Protectionism
In response to China’s rise, some governments have turned to tariffs, trade barriers, and restrictive policies.
While these measures may offer short-term protection, they do little to address the underlying structural gap.
The challenge is not simply one of market access—it is one of capability.
Without investment in processing, infrastructure, and industrial capacity, alternative supply chains remain incomplete. Protectionism, in this context, risks isolating economies rather than strengthening them.
More effective responses are likely to involve strategic partnerships and targeted investments, similar to emerging collaborations in rare earth supply chains.
Implications for India and Emerging Economies
For countries like India, the evolving resource landscape presents both opportunity and urgency.
India has ambitions to become a major player in clean energy manufacturing and supply chain diversification. It has a large domestic market, growing industrial capacity, and a strong talent base.
But it faces significant gaps.
Processing capabilities remain limited. Access to critical minerals is constrained. And integration across the value chain is still developing.
To compete effectively, India will need to move beyond isolated initiatives and adopt a more coordinated approach—linking resource access, industrial policy, and global partnerships.
More broadly, resource-rich nations face a strategic choice. They can remain suppliers of raw materials, or they can leverage current demand to build domestic industries and capture greater value.
China’s model offers one pathway. Whether others can develop alternatives will shape the future of the global economy.
The New Resource Order
The transition to a low-carbon economy is not just an environmental imperative—it is an industrial transformation.
At its core lies a simple reality: technologies may evolve, but they are built on physical resources. Control those resources, and you shape the trajectory of the transition.
China’s $120 billion investment surge is a reflection of this understanding. It is not merely securing supply—it is constructing a system.
The implications are profound.
As the world moves toward net zero, the question is no longer just who will innovate, but who will control the inputs that make innovation possible.
In that contest, the contours of a new resource order are already emerging—and China is at its centre.

India’s Power Future: 70% Non-Fossil Capacity by 2035-36, But Grid Challenges Loom
India targets 1121 GW power capacity by 2036 with 70% non-fossil share, but grid, storage and utilisation challenges remain, says CEA report.
India’s non-fossil power capacity is set to reach 70% by 2035-36, driven by rapid solar expansion, but grid constraints, storage gaps and utilisation challenges could shape the energy transition.
India is preparing for one of the most dramatic transformations in its energy sector, with the Central Electricity Authority outlining a future where clean energy dominates installed capacity but fossil fuels continue to underpin supply reliability.
The National Generation Adequacy Plan (2026-27 to 2035-36) presents the most detailed roadmap yet of how India’s electricity system will evolve over the next decade. It projects that India’s installed power capacity will reach 1,121 GW by 2035-36, with 70% (786 GW) coming from non-fossil sources, signalling a structural shift in the country’s energy mix.
At the same time, the report highlights a more complex reality: capacity expansion alone will not define the transition—utilisation, storage, and grid readiness will.
India Power Capacity 2035-36 to Cross 1,100 GW
India’s electricity system is expected to nearly double in scale over the next decade.
According to the report, net electricity generation is projected to rise from around 1,725 billion units today to 3,450 billion units by 2035-36, reflecting the country’s rapid economic growth and electrification push.
Solar energy is set to emerge as the dominant force in India’s power mix. Installed solar capacity alone is expected to exceed 500 GW, accounting for nearly 45% of total capacity, making it the single largest contributor to India’s energy basket.
The detailed breakdown of projected capacity includes:
- 315 GW coal
- 509 GW solar
- 155 GW wind
- 78 GW large hydro
- 20 GW gas
- 22 GW nuclear
These figures underline a system where renewables dominate capacity, but conventional sources remain critical to stability.
India Power Capacity 2035-36 vs Actual Generation Gap
One of the most important insights from the report is the divergence between installed capacity and actual electricity generation.
Despite renewables making up 70% of capacity, coal is expected to remain the backbone of electricity supply. The report projects coal will still account for 51% of total electricity generation (1,819 BU), while solar will contribute around 27% (984 BU).
This gap reflects the intermittent nature of renewable energy and the continued need for firm, dispatchable power.
As the report notes, “the source of firm power at present is predominantly coal-based generation.”
This highlights a key transition challenge: while India can rapidly build renewable capacity, replacing coal’s role in ensuring round-the-clock supply will require deeper systemic changes.
India Power Capacity 2035-36 Faces Grid Bottlenecks
While India’s renewable expansion has been rapid, the system’s ability to absorb this capacity remains constrained.
A major concern flagged in the analysis is the issue of stranded renewable capacity—power that is generated but cannot be transmitted due to grid limitations.
Vibhuti Garg, Director South Asia at the Institute for Energy Economics and Financial Analysis, said: “It is encouraging to see the national generation adequacy plan taking shape. India has made remarkable progress in expanding renewable energy capacity, with clean sources now accounting for more than 50% of installed capacity.
However, the real test lies not in capacity addition, but in how effectively this generation is utilised. Currently, over 37 GW of renewable energy capacity remains stranded—highlighting gaps in planning, integration, and grid readiness.
This underscores the urgent need to shift focus from merely adding capacity to ensuring efficient evacuation and utilisation. Strengthening transmission infrastructure and aligning it with demand centres is critical. As supply and demand increasingly diverge geographically, coordinated planning becomes essential.”
The report also notes that renewable energy generation is becoming more geographically dispersed, increasing the need for robust transmission networks to connect generation hubs with consumption centres.
India Power Capacity 2035-36 Needs Massive Storage Push
Energy storage emerges as the single most critical enabler of India’s clean energy transition.
The plan estimates that India will require 174 GW / 888 GWh of energy storage capacity by 2035-36, including battery storage and pumped hydro.
However, the current pipeline is far from sufficient:
- Only 10.6 GW of battery storage is under construction
- Additional capacity remains in tendering or early planning stages
This gap between projected need and current deployment highlights a major financing and policy challenge.
The report also emphasises that solar-plus-storage systems are emerging as an alternative, particularly for meeting peak demand during non-solar hours, but are yet to fully replace coal-based baseload generation.
India Power Capacity 2035-36 and Energy Security
The timing of the plan is significant, coming amid global energy market disruptions and geopolitical tensions.
Vibhuti Garg noted:“At a time when India remains exposed to global fuel supply disruptions due to geopolitical tensions, accelerating renewable energy integration is not just a climate imperative—it is an economic and energy security necessity.”
The report positions renewable energy not just as a climate solution, but as a strategic tool for reducing dependence on imported fuels.
EVs and Data Centres as New Demand Drivers
The plan also identifies electric vehicles and data centres as emerging sources of electricity demand.
These loads are expected to be geographically concentrated, requiring careful coordination between energy supply and demand planning.
Vibhuti Garg added: “This challenge will intensify with the rise of new demand drivers such as electric vehicles and data centres. These loads are often geographically concentrated, making it even more important to strategically plan clean energy supply in tandem with demand clusters.”
India’s power sector is entering a defining decade.
The National Generation Adequacy Plan makes it clear that the country is on track to build one of the world’s largest clean energy systems. But it also underscores that capacity alone is not enough.
The real transition will depend on:
- Grid infrastructure
- Energy storage deployment
- Demand-side planning
- Policy alignment with emerging technologies
As the report emphasises, the goal is not just to expand capacity, but to ensure a reliable, resilient, and cost-effective power system capable of meeting India’s rapidly growing electricity demand.

EVs avoided oil equal to 70% of Iran’s exports in 2025
Electric vehicles avoided oil equal to 70% of Iran’s exports in 2025, reshaping global energy security amid Middle East tensions.
When tensions rise around Iran, the world braces for oil shocks. Markets react, governments worry, and the Strait of Hormuz once again becomes the centre of global attention.
But in 2025, something quietly shifted beneath this familiar cycle of crisis.
Electric vehicles avoided oil consumption equivalent to nearly 70% of Iran’s exports.
According to analysis by Ember, the global EV fleet reduced oil demand by 1.7 million barrels per day, approaching the 2.4 million barrels per day exported by Iran through the Strait of Hormuz.
This is not just a milestone for clean energy. It marks the beginning of a structural change in how the world responds to geopolitical risk.
The world’s oil vulnerability is still profound
Despite rapid technological progress, the global economy remains deeply exposed to oil shocks.
Nearly 79% of the world’s population lives in oil-importing countries, making them vulnerable to disruptions in supply and price volatility.
The costs are enormous. For every $10 increase in oil prices, global import bills rise by around $160 billion annually.
At the heart of this vulnerability lies the Middle East—and specifically the Strait of Hormuz. This narrow passage carries around one-fifth of global oil exports, while the wider Gulf region accounts for 29% of global oil supply.
The concentration of supply through such a fragile corridor makes the global economy acutely sensitive to regional instability.
“This is Asia’s Ukraine moment,” said Daan Walter, principal at Ember. “Oil is the Achilles’ heel of the global economy… Asia’s oil vulnerability has been exposed by the current crisis.”
Even oil producers cannot escape the shock
One of the most counterintuitive realities of today’s energy system is that producing oil domestically does not shield economies from global price spikes.
Oil is traded in global markets. When supply is disrupted, prices rise everywhere.
In Texas, one of the world’s largest oil-producing regions, gasoline prices increased by more than 25% following recent geopolitical tensions—in some cases exceeding rises seen in oil-importing countries.
This reflects a fundamental truth: oil dependency is a global vulnerability, not a local one.
The true cost of fossil fuel dependence
The financial burden of this dependency is immense.
Net importing countries spent approximately $1.7 trillion on fossil fuel imports in 2024, with many economies losing significant portions of GDP to energy imports.
For developing economies, the impact is even more severe. Rising prices can strain public finances, disrupt industries, and increase the cost of living.
The report highlights a stark dynamic: when supply tightens, wealthier countries can outbid poorer ones, effectively pushing them out of the market.
Energy insecurity, in this sense, is not just an economic issue—it is a question of global inequality.
EVs are emerging as a geopolitical force
Against this backdrop, the rise of electric vehicles is beginning to alter the equation.
The fact that EVs avoided oil demand equivalent to 70% of Iran’s exports is not just symbolic—it is strategic.
It shows that demand-side transformation can counterbalance supply-side risk.
“Electric vehicles are increasingly cost-competitive with gasoline cars,” Walter said. “Oil volatility means EVs are a common-sense choice for countries wishing to insulate themselves from future shocks.”
The economic benefits are already visible:
- China saves over $28 billion annually in avoided oil imports
- Europe saves around $8 billion
- India saves about $0.6 billion
These savings highlight a critical shift: energy security is moving from controlling supply to reducing dependence.
A broader shift: the rise of “electrotech”
Electric vehicles are only one part of a wider transformation described in the report as “electrotech”—a combination of EVs, solar, wind, batteries, and heat pumps.
Together, these technologies can electrify more than three-quarters of global energy demand and significantly reduce fossil fuel imports.
If deployed at scale, they could cut import dependence by up to 70%, fundamentally reshaping global energy systems.
Unlike fossil fuels, which require continuous imports, these technologies provide long-term stability. Once installed, they operate without fuel costs, price volatility, or geopolitical exposure.
As the report puts it, this is the difference between “renting energy” and “owning it.”
The Strait of Hormuz: from chokepoint to turning point
The current crisis highlights the strategic importance of the Strait of Hormuz—but it may also accelerate its decline as a central pillar of global energy security.
Asia, which imports around 40% of its oil through the strait, is particularly exposed.
But unlike previous crises, countries now have viable alternatives.
Renewable energy costs have fallen sharply. EV adoption is accelerating across both developed and emerging markets. And electrification technologies are scaling faster than expected.
The report suggests this could become a defining moment—similar to how Europe’s response to the Ukraine crisis reshaped its energy strategy.
Peak oil may arrive sooner than expected
The implications extend beyond immediate crisis management.
The International Energy Agency had projected global oil demand would peak around 2029. But recent developments suggest that peak may arrive sooner.
Electrification is not only reducing demand—it is changing expectations about the future of energy.
The report notes that demand growth forecasts have already been revised downward, with the possibility that global oil demand could plateau—or even decline—earlier than anticipated.
Crises, historically, have accelerated structural transitions. This may be another such moment.
A structural shift beneath the headlines
Geopolitical tensions may dominate headlines, but the deeper story lies beneath.
The fossil fuel system—dependent on continuous trade through vulnerable chokepoints—is becoming increasingly fragile. At the same time, the technologies needed to replace it are becoming cheaper, faster, and more accessible.
The fact that EVs alone have already offset oil demand equivalent to most of Iran’s exports signals a profound shift.
It suggests that the balance of power in global energy is beginning to move—from regions that supply oil to technologies that reduce the need for it.
The Strait of Hormuz may remain a critical artery for now. But its grip on the global economy is loosening.
And for the first time in decades, the world has a credible path to reduce its dependence on it.
