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.

From Tehran Rooftops To Orbit: How Elon Musk Is Reshaping Who Controls The Internet
How Starlink turned the sky into a battleground for digital power — and why one private network now challenges the sovereignty of states
On a rooftop in northern Tehran, long after midnight, a young engineering student adjusts a flat white dish toward the sky. The city around him is digitally dark—mobile data throttled, social media blocked, foreign websites unreachable. Yet inside his apartment, a laptop screen glows with Telegram messages, BBC livestreams, and uncensored access to the outside world.
Scenes like this have appeared repeatedly in footage from Iran’s unrest broadcast by international news channels.
But there’s a catch. The connection does not travel through Iranian cables or telecom towers. It comes from space.
Above him, hundreds of kilometres overhead, a small cluster of satellites belonging to Elon Musk’s Starlink network relays his data through the vacuum of orbit, bypassing the state entirely.
For governments built on control of information, this is no longer a technical inconvenience. It is a political nightmare. The image is quietly extraordinary. Not because of the technology — that story is already familiar — but because of what it represents: a private satellite network, owned by a US billionaire, now functioning as a parallel communications system inside a sovereign state that has deliberately tried to shut its citizens offline.
The Rise of an Unstoppable Network
Starlink, operated by Musk’s aerospace company SpaceX, has quietly become the most ambitious communications infrastructure ever built by a private individual.
As of late 2025, more than 9,000 Starlink satellites orbit Earth in low Earth orbit (LEO) (SpaceX / industry trackers, 2025). According to a report in Business Insider, the network serves over 9 million active users globally, and Starlink now operates in more than 155 countries and territories (Starlink coverage data, 2025).
It is the largest satellite constellation in human history, dwarfing every government system combined.
This is not merely a technology story. It is a power story.
Unlike traditional internet infrastructure — fibre cables, mobile towers, undersea routes — Starlink’s backbone exists in space. It does not cross borders. It does not require landing rights in the conventional sense. And, increasingly, it does not ask permission.
Iran: When the Sky Replaced the State
During successive waves of anti-government protests in Iran, authorities imposed sweeping internet shutdowns: mobile networks crippled, platforms blocked, bandwidth throttled to near zero. These tactics, used repeatedly since 2019, were designed to isolate protesters from each other and from the outside world.
They did not fully anticipate space-based internet.
By late 2024 and 2025, Starlink terminals had begun appearing clandestinely across Iranian cities, smuggled through borders or carried in by diaspora networks. Possession is illegal. Penalties are severe. Yet the demand has grown.
Because the network operates without local infrastructure, users can communicate with foreign media, upload protest footage in real time, coordinate securely beyond state surveillance, and maintain access even during nationwide blackouts.
The numbers are necessarily imprecise, but multiple independent estimates provide a sense of scale. Analysts at BNE IntelliNews estimated over 30,000 active Starlink users inside Iran by 2025.
Iranian activist networks suggest the number of physical terminals may be between 50,000 and 100,000, many shared across neighbourhoods. Earlier acknowledgements from Elon Musk confirmed that SpaceX had activated service coverage over Iran despite the lack of formal licensing.
This is what alarms governments most: the state no longer controls the kill switch.

Ukraine: When One Man Could Switch It Off
The power — and danger — of this new infrastructure became even clearer in Ukraine.
After Russia’s 2022 invasion, Starlink terminals were shipped in by the thousands to keep Ukrainian communications alive. Hospitals, emergency services, journalists, and frontline military units all relied on it. For a time, Starlink was celebrated as a technological shield for democracy.
Then came the uncomfortable reality.
Investigative reporting later revealed that Elon Musk personally intervened in decisions about where Starlink would and would not operate. In at least one documented case, coverage was restricted near Crimea, reportedly to prevent Ukrainian drone operations against Russian naval assets.
The implications were stark: A private individual, accountable to no electorate, had the power to influence the operational battlefield of a sovereign war. Governments noticed.

Digital Sovereignty in the Age of Orbit
For decades, states have understood sovereignty to include control of national telecom infrastructure, regulation of internet providers, the legal authority to impose shutdowns, the power to filter, censor, and surveil.
Starlink disrupts all of it.
Because, the satellites are in space, outside national jurisdiction. Access can be activated remotely by SpaceX, and the terminals can be smuggled like USB devices. Traffic can bypass domestic data laws entirely.
In effect, Starlink represents a parallel internet — one that states cannot fully regulate, inspect, or disable without extraordinary countermeasures such as satellite jamming or physical raids.
Authoritarian regimes view this as foreign interference. Democratic governments increasingly see it as a strategic vulnerability. Either way, the monopoly problem is the same: A single corporate network, controlled by one individual, increasingly functions as critical global infrastructure.
How the Technology Actually Works
The power of Starlink lies in its architecture. Traditional internet depends on fibre-optic cables across cities and oceans, local internet exchanges, mobile towers and ground stations, and centralised chokepoints.
Starlink bypasses most of this. Instead, it uses thousands of LEO satellites orbiting at ~550 km altitude, user terminals (“dishes”) that automatically track satellites overhead, inter-satellite laser links, allowing data to travel from satellite to satellite in space, and a limited number of ground gateways connecting the system to the wider internet.
This design creates resilience: No single tower to shut down, no local ISP to regulate, and no fibre line to cut.
For protesters, journalists, and dissidents, this is transformative. For governments, it is destabilising.
A Private Citizen vs the Rules of the Internet
The global internet was built around multistakeholder governance: National regulators, international bodies like the ITU, treaties governing spectrum use, and complex norms around cross-border infrastructure.
Starlink bypasses much of this through sheer technical dominance, and it has become a company that: owns the rockets, owns the satellites, owns the terminals, controls activation, controls pricing, controls coverage zones… effectively controls a layer of global communication.
This is why policymakers now speak openly of “digital sovereignty at risk”. It is no longer only China’s Great Firewall or Iran’s censorship model under scrutiny. It is the idea that global connectivity itself might be increasingly privatised, personalised, and politically unpredictable.

The Unanswered Question
Starlink undeniably delivers real benefits, it offers connectivity in disaster zones, internet access in rural Africa, emergency communications in war, educational access where infrastructure never existed.
But it also raises an uncomfortable, unresolved question: Should any individual — however visionary, however innovative — hold this much power over who gets access to the global flow of information?
Today, a protester in Tehran can speak to the world because Elon Musk chooses to allow it.
Tomorrow, that access could disappear just as easily — with a policy change, a commercial decision, or a geopolitical calculation.The sky has become infrastructure. Infrastructure has become power. And power, increasingly, belongs not to states — but to a handful of corporations.
There is another layer to this power calculus — and it is economic. While Starlink has been quietly enabled over countries such as Iran without formal approval, China remains a conspicuous exception. The reason is less technical than commercial. Elon Musk’s wider business empire, particularly Tesla, is deeply entangled with China’s economy. Shanghai hosts Tesla’s largest manufacturing facility in the world, responsible for more than half of the company’s global vehicle output, and Chinese consumers form one of Tesla’s most critical markets.
Chinese authorities, in turn, have made clear their hostility to uncontrolled foreign satellite internet, viewing it as a threat to state censorship and information control. Beijing has banned Starlink terminals, restricted their military use, and invested heavily in its own rival satellite constellation. For Musk, activating Starlink over China would almost certainly provoke regulatory retaliation that could jeopardise Tesla’s operations, supply chains, and market access. The result is an uncomfortable contradiction: the same technology framed as a tool of freedom in Iran or Ukraine is conspicuously absent over China — a reminder that even a supposedly borderless internet still bends to the gravitational pull of corporate interests and geopolitical power.

Ancient lake sediments suggest India’s monsoon was far stronger during medieval warm period
New palaeoclimate evidence from central India suggests that the Indian Summer Monsoon was significantly stronger during the medieval warm period than previously believed
India’s monsoon history may be more intense than previously assumed, according to new palaeoclimate evidence recovered from lake sediments in central India. Scientists analysing microscopic pollen preserved in Raja Rani Lake, in present-day Korba district of Chhattisgarh, have found signs of unusually strong and sustained Indian Summer Monsoon rainfall between about 1,060 and 1,725 CE.
The findings come from researchers at the Birbal Sahni Institute of Palaeosciences (BSIP), an autonomous institute under the Department of Science and Technology, and are based on a detailed reconstruction of vegetation and climate in India’s Core Monsoon Zone (CMZ)—the region that receives nearly 90 percent of the country’s annual rainfall from the Indian Summer Monsoon.
Reading climate history from pollen
Researchers extracted a 40-centimetre-long sediment core from Raja Rani Lake. These layers of mud record environmental changes spanning roughly the last 2,500 years. Embedded within them are fossil pollen grains released by plants that once grew around the lake.
By identifying and counting these grains—a method known as palynology—the team reconstructed past vegetation patterns and inferred climate conditions. Forest species that thrive in warm, humid environments point to periods of strong rainfall, while grasses and herbs are indicators of relatively drier phases.
According to the scientists, the pollen record from the medieval period shows a clear dominance of moist and dry tropical deciduous forest taxa. This points to a persistently warm and humid climate in central India, driven by a strong monsoon system, with no evidence of prolonged dry spells within the CMZ during that time.
Medieval Climate Anomaly linked to stronger monsoon
The period of intensified rainfall coincides with the Medieval Climate Anomaly (MCA), a globally recognised warm phase dated to roughly 1,060–1,725 CE. The study suggests that the strengthened Indian Summer Monsoon during this interval was shaped by a combination of global and regional drivers.
In a media statement, the researchers noted that La Niña–like conditions—typically associated with stronger Indian monsoons—may have prevailed during the MCA. Other contributing factors likely included a northward shift of the Inter Tropical Convergence Zone, positive temperature anomalies, higher sunspot numbers and increased solar activity.
Why this matters today
The Core Monsoon Zone is particularly sensitive to fluctuations in the Indian Summer Monsoon, making it a key region for understanding long-term hydroclimatic variability during the Late Holocene (also known as the Meghalayan Age). Scientists say insights from this period are crucial for contextualising present-day monsoon behaviour under ongoing climate change.
The BSIP team said high-resolution palaeoclimate records such as these can strengthen climate models used to simulate future rainfall patterns. Beyond academic interest, the findings have implications for water management, agriculture and climate-resilient policy planning in monsoon-dependent regions.
By revealing that central India once experienced a more intense and sustained monsoon than previously recognised, the study adds a deeper historical perspective to debates on how the Indian monsoon may respond to current and future warming.

Reliance to build India’s largest AI-ready data centre, positions Gujarat as global AI hub
As part of making Gujarat India’s artificial intelligence pioneer, in Jamnagar we are building India’s largest AI-ready data centre: Mukesh Ambani
Reliance Industries Limited, India’s largest business group, has announced plans to build the country’s largest artificial intelligence–ready data centre in Jamnagar, a coastal industrial city in the western Indian state of Gujarat, as part of a broader push to expand access to AI technologies at population scale.
The announcement was made by Mukesh Ambani, chairman and managing director of Reliance Industries, during the Vibrant Gujarat Regional Conference for the Kutch and Saurashtra region, a government-led investment and development forum focused on regional economic growth.
Ambani said the Jamnagar facility is being developed with a single objective: “Affordable AI for every Indian.” He positioned the project as a foundational investment in India’s digital infrastructure, aimed at enabling large-scale adoption of artificial intelligence across sectors including industry, services, education and public administration.
“As part of making Gujarat India’s artificial intelligence pioneer, in Jamnagar we are building India’s largest AI-ready data centre,” Ambani said, adding that the facility is intended to support widespread access to AI tools for individuals, enterprises and institutions.
Reliance also announced that its digital arm, Jio, will launch a “people-first intelligence platform,” designed to deliver AI services in multiple languages and across consumer devices. According to Ambani, the platform is being built in India for both domestic and international users, with a focus on everyday productivity and digital inclusion.
The AI initiative forms part of Reliance’s broader commitment to invest approximately Rs 7 trillion (about USD 85 billion) in Gujarat over the next five years. The company said the investments are expected to generate large-scale employment while positioning the region as a hub for emerging technologies.
The Jamnagar AI data centre is being developed alongside what Reliance describes as the world’s largest integrated clean energy manufacturing ecosystem, encompassing solar power, battery storage, green hydrogen and advanced materials. Ambani said the city, historically known as a major hub for oil refining and petrochemicals, is being re-engineered as a centre for next-generation energy and digital technologies.
The announcements were made in the presence of Indian Prime Minister Narendra Modi and Gujarat Chief Minister Bhupendra Patel, underscoring the alignment between public policy and private investment in India’s long-term technology and infrastructure strategy.
