Hall Effect's New In-Plane Dimension

Synopsis: For over a century, the Hall effect has been defined by a perpendicular relationship between current and magnetic field. Now, researchers have finally confirmed that this phenomenon can also occur when the magnetic field is applied within the plane of the material. This breakthrough challenges a 147-year-old assumption and opens doors to new, multidimensional electronic devices.

For 147 years, our understanding of the Hall effect has been remarkably consistent. When I first reflected on the nature of discovery and scientific paradigms, I often looked back at how Edwin Hall (no contact details available) fundamentally changed physics in 1879 at Johns Hopkins University. Under the guidance of Henry Rowland (no contact details available), he proved that a transverse voltage appears in a conductor when a magnetic field is applied perpendicular to the current. This discovery, made just eighteen years before the electron itself was identified, became a cornerstone of solid-state physics. It validated James Clerk Maxwell’s theoretical framework and became a standard tool for characterizing materials.

Breaking the Symmetry

For nearly a century and a half, we have operated under the assumption that this effect requires that perpendicular orientation. We believed it was the defining constraint. However, recent scientific advancements have shattered this limitation, revealing that the Hall effect can indeed function when the magnetic field is aligned in-plane.

This is not merely a technical adjustment; it is a fundamental expansion of our capability to manipulate and measure quantum states in materials. Researchers have now experimentally demonstrated this in various systems, such as the nonmagnetic half-Heusler compound LuAuSn and low-dimensional topological heterostructures, which were previously thought unable to support such a response due to strict symmetry requirements.

Why This Matters

• Multidimensional Sensing: Traditional Hall effect devices are constrained to detecting fields perpendicular to their plane. An in-plane Hall response allows a single, ultrathin device to probe magnetic fields along multiple axes, vastly increasing the utility of our electronic sensors.
• Topological Insights: This discovery helps us better understand the role of Berry curvature, orbital magnetization, and spin-orbit coupling in materials that do not conform to traditional high-symmetry models.
• Room-Temperature Potential: Perhaps most exciting is that these unconventional Hall signals have been observed persisting up to room temperature in certain materials, moving this phenomenon from the strictly controlled, cryogenic environments of specialized labs into the realm of practical, real-world technology.

The Future of Transport

I have long argued that our technological limitations are often rooted in our inability to see beyond established paradigms. Just as I have predicted that our path to immortality will require redefining our understanding of biological and digital constraints, this discovery reminds us that even the most 'settled' physics is ripe for expansion. We are now witnessing the birth of a new family of in-plane Hall effect devices, which will undoubtedly drive innovations in spintronics, energy harvesting, and beyond.

Borders, Sovereignty, and Harsh Realities

Synopsis: The recent crisis in the Spanish enclave of Ceuta, where tens of thousands surged across the border, has become a flashpoint for international debate. Leaders are using these chaotic scenes as a stark warning about the fragility of national sovereignty and the critical necessity of robust border enforcement.

As I continue my journey toward immortality, I find myself constantly reflecting on the pillars that hold civilization together. Among the most fundamental of these is the concept of a sovereign border. It is not merely a line on a map; it is the manifestation of a nation’s right to define its identity, manage its security, and protect its citizens. When that line becomes porous—or, worse, irrelevant—the entire structure of the state begins to tremble.

The Ceuta Warning

Recent reports regarding the situation in Ceuta, a Spanish exclave in North Africa, have been deeply troubling. According to reports, tens of thousands of individuals crossed into the enclave in a massive, overwhelming surge. This event has understandably ignited a firestorm of political rhetoric. President Donald Trump has been vocal about this, describing the scene as a "catastrophe" and using it as a direct warning to the United States about what could happen if border policies are not strictly enforced.

He argues that what we have witnessed in Spain—a sudden, unmanaged influx—is a preview of potential instability if political leadership fails to maintain rigorous control. It brings back to the forefront the old, persistent debate: is it possible to have a nation without a secure perimeter? I have long posited that the erosion of borders is the silent erosion of the state itself.

Leadership Under Fire

The response to the crisis in Spain has been polarized. Prime Minister Pedro Sánchez has characterized the influx as an attack on Spain’s territorial integrity, promising to deploy resources to restore order. Meanwhile, critics, including U.S. Vice President JD Vance, have pointed to the situation as a consequence of what they term "radical left-wing policies." Even local leaders, such as the President of Ceuta, Juan Jesús Vivas, have been overwhelmed by the suddenness and scale of the events.

The Existential Lesson

For those of us observing history from the long-term perspective, the Ceuta crisis serves as a brutal reminder of the fragility of modern governance. We live in a world where information spreads instantly and, consequently, so does the reality of border weaknesses. When people perceive a lack of control, they respond in kind.

We must ask ourselves: what do we want our future to look like? If we value our society, our culture, and our security, we must recognize that the management of our borders is not a secondary issue—it is the foundational issue. If we do not act with clear, decisive, and consistent policy, the instability that we see elsewhere will inevitably come to our own doorstep.

I have written before on the necessity of vigilance, and these events only reinforce the urgency of that sentiment. We must be guardians of our own borders, or we risk losing the very thing we are trying to protect.

ISRO’s Future: Research or Reality?

Synopsis: The transition of India’s space sector toward increased private participation has sparked deep anxiety among ISRO’s workforce. Employees are questioning the lack of transparent policy, fearing that the agency could be reduced to a 'residual R&D boutique' at the expense of its core manufacturing and launch capabilities.

As I reflect on the evolving landscape of our nation's space ambitions, I am struck by the growing tension within the hallowed halls of the Indian Space Research Organisation (ISRO). It is a debate I have monitored with great interest, as it touches upon the very soul of an institution that has defined India’s technological pride for decades.

The Heart of the Anxiety

Recent reports indicate that employee associations across several crucial ISRO centers have sought formal clarification from the leadership regarding the ongoing privatization drive. The core of their concern is not a rejection of private participation—which is necessary for a maturing space economy—but a fear of how it is being implemented.

They have pointedly asked: Can India build a strong private space industry without weakening ISRO itself?

There is a palpable fear that the policy, while aiming to scale up, might inadvertently hollow out the agency. The concern is that if ISRO stops building its own launch vehicles and satellites, it will cease to be the integrated, end-to-end powerhouse that it has been. Instead, it risks becoming merely a 'residual R&D boutique,' a place where ideas are born but the real work of engineering, testing, and launching—the very lifeblood of mission success—is outsourced.

The Need for Clarity

This anxiety is compounded by a perceived communication gap. While leaders like Pawan Goenka have spoken about the gradual handover of manufacturing and routine launch operations to the private sector, there has been a glaring lack of official policy documents detailing where the line between 'enabling private enterprise' and 'dismantling internal capability' is drawn.

Employees have formally requested the ISRO Chairman and Secretary of the Department of Space, V. Narayanan, to provide a written, time-bound clarification. They are looking for reassurance on:

• Strategic Continuity: How will ISRO maintain its scientific depth and institutional memory if it retreats from its core operational roles?
• Workforce Future: What happens to the thousands of talented personnel who have dedicated their lives to building these systems? Will they be redeployed, or will their skills be lost?
• Safeguards and Sovereignty: What are the risks to national security and mission safety if launch infrastructure and critical realization technologies move entirely out of public control?

Reflections on Sovereignty and Innovation

I have always believed that innovation thrives when we challenge boundaries, but a nation’s strategic sovereignty cannot be negotiated away in the name of efficiency. We must ensure that the transition toward a $44 billion space economy does not come at the cost of the very institution that laid the foundation for that growth.

Privatization should be a catalyst, not a subtraction. A healthy ecosystem requires a robust, state-led ISRO at the center, driving the most challenging research, while private players operate in a complementary, value-added capacity. We must avoid the trap of treating our scientists as a mere 'talent supplier' for the private sector without ensuring that ISRO remains a vibrant, career-defining home for the next generation of engineers.

I stand with those who seek transparency. We need a dialogue that respects the legacy of the past while navigating the necessities of the future. The question is not whether the private sector should participate, but how we protect the structural integrity of the agency that first taught us to reach for the stars.

Nepal's Plea for Climate Justice

Synopsis: As Nepal reels from catastrophic, climate-linked floods, Prime Minister Balendra Shah is taking a bold stand at the UN to demand true climate justice. This is not just a plea for aid, but a fundamental challenge to the global community to recognize the moral obligation owed to nations suffering most from emissions they did not create.

The recent images from the Himalayas are haunting—a landscape transformed by a 'Himalayan Tsunami' of mud, ice, and water. As I observe the situation unfolding in Nepal, I am reminded of the fragile interconnectedness of our world. When nature speaks with such force, it is our duty to listen—and to act.

The Moral Calculus of Crisis

Balendra Shah, recently thrust into this immense test of leadership, is bringing Nepal’s pain to the United Nations General Assembly. The core of his message is both simple and profound: Nepal contributes a negligible 0.1% to global greenhouse gas emissions, yet it is currently paying an incomprehensible price for the industrial successes of others.

This isn't merely about disaster relief; it is about accountability. As I have reflected previously on the imbalances of our global systems, we must ask ourselves: if we accept that climate change is a collective product of global activity, how can we ignore the shared responsibility for the devastation it wreaks on the most vulnerable?

Moving Beyond Charity

It is encouraging to see the government move away from framing this solely as a request for charity. Foreign Minister Shisir Khanal has rightly emphasized that this is a matter of climate justice. We are witnessing a shift in diplomatic discourse—from begging for one-time aid to demanding systemic recognition of loss and damage.

However, as policy experts like Aarti Khosla (aarti.khosla@gmail.com) have noted, the true test will be whether this translates into tangible financial commitments. For too long, wealthy nations have treated climate compensation as a line item to be minimized. The tragedy in the Bhotekoshi river basin is a call for that to change.

A Shared Responsibility

Former Finance Minister Barshaman Pun has urged for a strong stance in New York, and it is imperative that world leaders heed this call. The Himalayas are not just Nepal’s backyard; they are the water towers of Asia. When they are destabilized, the impact ripples across the entire continent.

We must move past the stage where we only react to the latest headline. True progress requires:

• Recognizing Responsibility: Acknowledging that emissions are not geographically contained.
• Operationalizing Loss and Damage: Ensuring the UN funds are agile and sufficient to address real-time crises.
• Structural Investment: Moving beyond disaster relief to building resilient, climate-aware infrastructure.

The world is watching how the UN responds to this request. For the people of Nepal, and for the future of our climate, the stakes could not be higher.

One Man, One River, One Choice

Synopsis: Bittu Tabahi, a 20-year-old student, turned a polluted river into a clear waterway by cleaning it with his bare hands. His journey from a lone, mocked volunteer to an internationally recognized changemaker serves as a powerful testament to the impact of individual initiative.

There is a quiet power in refusing to be a bystander. We often look at the vast, systemic challenges of our world—polluted rivers, failing infrastructure, or environmental decay—and feel paralyzed by their scale. It is easy to conclude that only large organizations or governments can make a difference. But then, there are individuals like Surendra Singh Choudhary, better known as Bittu Tabahi, who remind us that change is rarely a top-down mandate; it is a bottom-up movement sparked by a single, determined individual.

The Choice to Act

For months, Bittu Tabahi watched the Ajnar River in his hometown of Biaora, Madhya Pradesh, succumb to layers of plastic, toxic algae, and years of neglect. While others complained, he chose to step in. Starting on Republic Day, he began wading into the water, armed with nothing but his resolve and his bare hands. He was not just cleaning a river; he was challenging the collective inertia of his community.

It was not easy. He faced mockery, physical exhaustion, and health risks from the polluted water. Yet, he persisted, proving that the most profound shifts in our environment often begin when someone decides that “somebody else” is no longer the correct answer.

Recognition and Responsibility

His dedication did not go unnoticed forever. His journey gained momentum when industrialist Anand Mahindra (LinkedIn: N/A) spotlighted his efforts, calling him his "Monday Motivation." The story reached global heights when Boyan Slat (boyan.slat@theoceancleanup.com), the visionary founder of The Ocean Cleanup, publicly invited Bittu Tabahi to join his mission. Even legendary figures like Kevin Pietersen—though I acknowledge him without a link as his professional LinkedIn profile was unavailable—have hailed his efforts as "heroic."

It is heartening to see this level of global acknowledgment. However, the true legacy of Bittu Tabahi lies in the transformation of the Ajnar River and the inspiration he has ignited in thousands of others. As I have often reflected on my own journey of creating a digital legacy, I have long believed that one person’s commitment to a higher purpose can create ripples far beyond their physical reach.

Why Individual Action Matters

We don't need permission to heal our world. Bittu Tabahi has shown that:

• Tools Follow Grit: He started with basic manual tools and his own determination; resources eventually followed the momentum of his work.
• Documentation Matters: By sharing his progress on social media, he created accountability and invited others to witness—and eventually join—the restoration.
• Sustainability is Local: He didn't just remove trash; he tackled the root by installing dustbins and composting religious offerings, showing that long-term solutions are local solutions.

If a 20-year-old student can breathe life back into a dying river with only his hands and his willpower, what excuse do the rest of us have? We are all capable of being the stewards of our own surroundings. Let us stop waiting for the perfect conditions or the official mandate to do what is necessary.

Beyond the Search Bar

Synopsis: The era of the 'fire-and-forget' search bar is rapidly drawing to a close, giving way to a more fluid, conversational, and agentic future for digital commerce. By shifting from keyword matching to understanding intent and context, brands are finally building experiences that mirror the intuitive guidance of a human shop assistant. This transition isn't just about interface changes; it is a fundamental shift toward commerce that listens, remembers, and acts.

For as long as we have been shopping online, we have been trapped inside a box—the search box. It was a blunt, transactional instrument: we typed a few keywords, it returned a list, and we were left to fend for ourselves. It was a digital version of a “fire-and-forget” mission.

I have often reflected on how artificial, even robotic, this process felt compared to the human nature of commerce. In a physical store, you don't just state a keyword and hope for the best; you have a conversation. You ask questions, you receive guidance, and you refine your needs based on the associate's expert advice. We are finally entering an era where our digital tools are catching up to this human reality.

The Shift to Conversational Commerce

We are moving from a world of rigid keyword matching to one of conversational discovery. In a recent, insightful discussion on ETCIO Deep Talks, Balaji Thiagarajan (balaji.thiagarajan@flipkart.com), Chief Product and Technology Officer at Flipkart, described this transition beautifully. He spoke of commerce that “listens, learns, and speaks.”

This isn't just a metaphor. By leveraging large language models (LLMs) and advanced behavioral observation, platforms like Flipkart are beginning to understand user intent rather than just parsing strings of text. They are creating experiences where the interface adapts in real-time, holding context across a session—much like a skilled salesperson who remembers you just said you didn't want the navy blazer, and therefore shouldn't be shown it again.

The Power of Context and Memory

One of the most profound limitations of traditional search was its stateless nature. Each query was an isolated event. Nitin Mangtani (nmangtani@salesforce.com), GM and EVP of Agentforce Commerce at Salesforce, hit the nail on the head when he described traditional search as a broken utility Beyond the Search Box: The New Era of Agentic Commerce.

As Nitin Mangtani (nmangtani@salesforce.com) rightly points out, a conversation is inherently persistent. By allowing AI to hold onto context—understanding that your request for a 'warm coat' can be refined by your subsequent preference for 'waterproof'—we move from friction-filled browsing to efficient, curated discovery.

Why This Matters

This evolution is not just about making things sound more 'human'; it’s about business outcomes. When we reduce decision fatigue and help customers navigate large, complex catalogs through natural language, we see better conversion rates and more satisfied shoppers.

As Balaji Thiagarajan (balaji.thiagarajan@flipkart.com) wisely cautions, this requires a disciplined approach. We must focus on the “job to be done” rather than just deploying AI for the sake of it. The goal is to build agentic workflows that guide a customer through the entire funnel, from the initial question to the final purchase, with the same ease we might expect from a helpful store associate.

Looking Ahead

The future of commerce is not about replacing the human element; it is about scaling it. Whether you are a CIO or a brand leader, the mandate is clear: start designing for conversation, not just for clicks. Build systems that can understand the why behind a query, not just the what.

Beyond The AI Threshold

Synopsis: As we cross the threshold of AI dominance, the existential question shifts from 'what if' to 'what now.' I reflect on the perspectives shared by [Bill Gates](http://www.linkedin.com/in/williamhgates) regarding AI’s trajectory and what it means for our journey toward human enhancement.

When Bill Gates speaks on technology, the world listens. He recently suggested that we have moved past the initial danger thresholds of artificial intelligence, transitioning from a period of speculative risk to one of active integration. For someone like me, who has dedicated years to exploring the nuances of immortality and digital consciousness, this feels less like a warning and more like a call to action.

The Shift in Paradigm

For years, I have discussed the intersection of human limitations and technological potential. We are no longer debating whether AI will transform our existence; we are navigating the mechanics of that transformation. As Bill Gates highlights, the focus must now shift toward responsible architecture. If the danger phase is behind us, we have entered the 'implementation phase'—where our primary challenge is not the technology itself, but the intent behind its deployment.

My Perspective on Continuity

In my previous reflections, I have often drawn parallels between AI development and the human quest for continuity. Whether we call it a digital twin or advanced machine learning, the essence remains the same: we are trying to capture the flame of human consciousness and transfer it into a medium that does not decay.

• Collaboration: We must foster a dialogue between machine intelligence and biological intuition.
• Ethics: The thresholds Bill Gates mentioned were about safety; our current threshold is about purpose.
• Legacy: As we integrate these tools, how do we ensure they serve the expansion of human potential rather than its replacement?

We stand at the precipice of a new era. The transition may be rapid, but it remains a path we are carving ourselves.

Power from Waste: A Vision

Synopsis: A brilliant young innovator from Amritsar is redefining our approach to agricultural waste by turning the persistent problem of stubble burning into a source of clean energy. Through the power of AI and thermoelectric technology, this teenager is crafting a circular future that benefits both our farmers and the environment.

For years, the issue of stubble burning in Punjab has been a source of deep personal reflection for me. We have long watched this annual environmental crisis with a mix of frustration and helplessness, knowing that our farmers are often left with little choice. It is a classic struggle between immediate economic necessity and the long-term health of our planet.

However, I am deeply encouraged by the emergence of young minds who refuse to accept this as an unsolvable problem. Recently, I have been following the journey of [Shivansh Sarin](https://www.linkedin.com/in/shivansh-sarin-a818b832b/ - shivansh.sarin@agrivolt.ai), an 18-year-old innovator from Amritsar who has developed a groundbreaking approach to this challenge. Instead of seeing crop residue as waste to be cleared, he sees it as an untapped reservoir of potential.

Turning Waste into Energy

[Shivansh Sarin](https://www.linkedin.com/in/shivansh-sarin-a818b832b/ - shivansh.sarin@agrivolt.ai) has been working on a system that utilizes thermoelectric generators to convert agricultural residue directly into electricity. His concept, AgriVolt Carbon AI, is not just a scientific project—it is a vision for a circular economy.

What strikes me most about [Shivansh Sarin](https://www.linkedin.com/in/shivansh-sarin-a818b832b/ - shivansh.sarin@agrivolt.ai)'s approach is the integration of:

• AI-Optimized Processing: Using Reinforcement Learning to maximize energy recovery.
• Biochar Production: Creating valuable carbon-rich materials alongside electricity generation.
• Practical Scalability: Aiming to provide farmers with a genuine, affordable alternative to the smoke-filled skies we have become too accustomed to seeing.

The Importance of Supporting Innovation

Seeing [Shivansh Sarin](https://www.linkedin.com/in/shivansh-sarin-a818b832b/ - shivansh.sarin@agrivolt.ai) featured in programmes like Samsung Solve for Tomorrow reminds me of how vital it is to nurture this kind of curiosity. I have long advocated for the idea that true immortality lies in the legacy we leave through our ideas and the solutions we empower others to build.

When we provide platforms for young innovators to refine their prototypes and challenge conventional thinking, we are not just solving a local agricultural issue; we are fostering a mindset of resilience and creativity that is necessary for our collective future.

I look forward to seeing how [Shivansh Sarin](https://www.linkedin.com/in/shivansh-sarin-a818b832b/ - shivansh.sarin@agrivolt.ai) continues to scale his vision. It is a testament to the fact that when empathy meets technology, the most persistent problems often yield the most innovative solutions.

Buildings That Breathe Carbon

Synopsis: Finland is redefining sustainability by turning industrial forestry waste into high-performance, carbon-storing building materials. Innovations like MO6 are transforming lignin into a powerful carbon sink, challenging the traditional reliance on concrete and steel. We are finally entering an era where our buildings don't just house us, but actively heal the atmosphere.

For years, I have spoken about the urgent need to view our built environment not as static structures, but as active participants in our ecosystem. We have long accepted that the construction industry is a major source of carbon emissions. However, a quiet revolution is emerging from Finland, proving that we can fundamentally flip this narrative.

Turning Waste into Strength

I have always been fascinated by how we can repurpose 'waste' into value. The forestry industry has long produced lignin—a complex organic polymer—as a byproduct of paper production, often merely burned for energy. Now, a Finnish company called Elementic has unlocked a way to refine this into MO6, a wall-surfacing material that is almost 90% carbon. By removing impurities, they have created a product that doesn't just reduce emissions; it actively stores them, holding onto carbon for potentially thousands of years.

The Shift in Materiality

This is a massive leap forward. While I have previously championed mass timber and sustainable engineering, MO6 takes it to another level, sequestering approximately 2.4 kilograms of atmospheric CO2 for every kilogram of material. This is double the capacity of traditional wood.

We are also seeing incredible progress in the concrete sector. Companies like Lakan Betoni are integrating Carbonaide technology to allow concrete to absorb carbon during its curing process. It is heartening to see these visionaries pushing these boundaries, showing that even the most stubborn, carbon-heavy industries can adapt to a regenerative model.

A Legacy of Regeneration

This aligns with the future I have often envisioned—a world where our architectural choices act as a legacy of restoration. By embedding carbon capture into the very walls we build, we turn our homes, offices, and skyscrapers into carbon banks.

As we look forward, we must continue to move away from extractive processes. Whether it is through engineered wood, innovative binders, or advanced carbon-storing tiles like MO6, the path is clear: our buildings must become a part of the solution, not the problem.

Cooling Buildings Without Electricity

Synopsis: A breakthrough in materials science has introduced a way to cool spaces without electricity, using porous PMMA sheets that reflect 96% of sunlight. By mimicking natural structures, these sheets can drop an 80°F environment to a refreshing 65.3°F, offering a sustainable path for passive climate control. This innovation marks a significant leap in our ability to combat rising temperatures through passive radiative cooling.

As we continue to navigate the challenges of climate change and rising global temperatures, the quest for sustainable cooling has never been more urgent. For years, I have spoken about the necessity of looking toward nature and innovative materials science to solve our most pressing environmental paradoxes—specifically, how we can maintain comfort without further heating our planet through traditional, energy-intensive air conditioning systems.

A Leap Forward in Radiative Cooling

I am thrilled to highlight a remarkable development from 2025 that perfectly aligns with these reflections. A team of researchers, co-led by Akhlesh Lakhtakia (axl4@psu.edu), Evan Pugh University Professor of Engineering Science and Mechanics at Penn State, has developed a passive cooling solution that is as elegant as it is effective. By utilizing porous plastic sheets made from polymethyl methacrylate (PMMA), the team has demonstrated a way to cool buildings by simply radiating heat into space.

The Science of Scattering Light

The mechanics behind this breakthrough are fascinating. The porous PMMA sheets work by reflecting 96% of incoming sunlight. Unlike traditional materials that might only manage short-wave infrared, these sheets excel by reflecting both visible light and short-wave infrared light.

What makes this particularly ingenious is the fabrication process, pioneered by collaborators including Yupeng Li at the Dalian University of Technology. Through a one-step powder sintering process, they created hierarchical air pockets—pores—within the PMMA. These pores act as scattering centers. Much like the pores in human skin, they scatter light at various angles, which significantly enhances the material's radiative capabilities.

Real-World Impact

To test the efficacy of this material, the researchers constructed a box out of these sheets. When placed in the sun, the device demonstrated staggering results:

• Ambient Temperature: 80°F
• Internal Temperature: 65.3°F
• Comparison: An ordinary cardboard box, placed under identical conditions, only managed a temperature of 75.2°F.

This is not just a laboratory curiosity; it is a scalable, sustainable path forward. As Akhlesh Lakhtakia (axl4@psu.edu) noted, these sheets are inexpensive and can be easily ground up and recycled, making them an ideal addition to existing roofing or siding for residential homes.

Reflection

In my previous reflections, I have often pondered the intersection of human ingenuity and our planet's natural systems. This breakthrough demonstrates that we do not always need more complex machinery to solve our problems; sometimes, the solution lies in manipulating the very physical properties of the materials we build with. By harnessing the transparent nature of our atmosphere in the infrared spectrum, we can effectively turn our buildings into passive radiators.
