Discovery of molecular structure of primary genetic material of life

Published

on

World DNA Day falls on 25 April:

On 25 April 1953, Watson and Crick published an article, in the acclaimed journal “Nature” titled “Molecular structure of nucleic acids: A structure for deoxyribonucleic acid”.

The one-page article largely based on theoretical arguments and the previous work of Rosalind Franklin who examined DNA using X-rays, changed the world forever by explaining how genetic information is copied and transmitted.

Everyone concerned with promoting science in the country should be aware of the story behind the discovery of DNA and tell it to their children and students and remind the policymakers.

The world commemorates the transformative event on 25th April every year. An example vividly illustrates how intense curiosity and imagination, rather than mere indulgence in technologies, leads to groundbreaking discoveries.

DNA Day is also intended to celebrate the completion of the Human Genome Project in 2003. Genome means the entire set of genetic information characterising an organism.

Heredity and inheritance

Heredity is the cause of transferring traits from parents to their offspring. The closely related word “inheritance “refers to the specific nature of the transmitted trait. For example, we say intelligence is hereditary in their family and he inherited his father’s intelligence.

The resemblance of progeny to parentage was common knowledge, taken for granted and considered a blending of maternal and paternal traits. Philosophers of antiquity proposed several theories to explain the inheritance of parental traits by the offspring. Hippocrates believed the essence of all body parts of the parents are incorporated into the male and female germinal essence and therefore the offspring display characteristics as a proportionate blend. Aristotle offered a different explanation. He argued that the active principle is in the male seminal fluid and the mother’s blood provided the original body material. The inaccuracy of these theories was apparent. Sometimes children possess qualities akin to grandparents rather than parents. Fathers or mothers of humans and animals, deformed by accidents or disease, gave birth to normal children- a clear proof that the acquired characters are not inherited. Children of a blue-eyed mother and a brown-eyed father have either blue or brown eyes but not a blend of blue and brown.

Two golden sayings in our culture, “Arae gathi nare” and “Jammeta wada lokuei purrudha” (“Hereditary characters persist” and “Habits overtake heredity “), agree more with modern genetics, than the views of Hippocrates and Aristotle.

Gregor Mendal’s groundbreaking experiment

The Austrian mathematician cum botanist, Gregor Mendel was the first to conduct a systematic investigation to understand the cause of heredity. Being unconvinced of the traditional explanations, he carried out a series of experiments lasting eight years to determine how the traits (plant height, seed color, flower color etc.) of pea plants are transmitted from generation to generation. When Mendel cross pollinated tall and short plants, he found that the progeny was entirely tall. However, when first generation tall plants were allowed to self-pollinate, the missing short trait reappeared at a statistically significant probability of 25 percent. Mendel’s work provided an unequivocal proof that traits do not blend but exist as unique entities, manifested from generation to generation following a predictable mathematical pattern.

Mendel’s finding remained unrecognized for more than 30 years. His ideas were too far ahead of time and biologists were shy of mathematics. In the early 1900s several European botanists arrived at the same conclusion based on independent experiments. With the advancement of microscopy, a great deal of information about plant and animal cells was gathered. A key finding was the presence of colored bodies in the cell nucleus named chromosomes, seen separating during cell division, leading to the hypothesis that Mendel’s genetic units (genes) should be physical entities present in the chromosomes.

Chemists and biologists wondered what the genetic material in chromosomes made off. Is it a protein, carbohydrate or a lipid? Most biological materials are constituted of these substances.

Discovery of DNA

Great discoveries are made by unusual people. The Swiss Friedrich Miescher belonged to a clan of reputed physicians. Following family tradition, he qualified as a doctor but did not engage in profitable practice of medicine. He decided to do research to understand the foundations of life. In search for new biological substances, he experimented with pus deposited in bandages and extracted a substance rich in phosphates but very different from proteins. The new substance called “nuclein” was indeed DNA. Later, the German biochemist Albrecht Kossel following the Miescher’s work, showed that DNA contains four crucial compounds, adenine (A), cytosine (C), guanine (G) and thymine (T), known as nucleotide bases.

Avery – MacLeod – McCarthy Experiment

The flu pandemic of 1918 killed an estimated 50 million people worldwide due to the pneumonia that followed the viral infection. Pneumonia was caused by the virulent bacterium Streptococcus pneumoniae. The British bacteriologist, Frederick Griffith attempting to find a vaccine for pneumonia, worked with two strains of Streptococcus pneumoniae, one virulent causing pneumonia in mice, and the other avirulent to them. He found that neither the virulent strain denatured by heating nor the live avirulent strain injected into mice caused the disease, whereas a mixture of the denatured virulent strain and the live avirulent strain was deadly to mice just as the virulent one. He concluded that some chemical compound present in the virulent strain – a transforming principle – has changed the avirulent strain to the virulent strain.

In 1944, Oswald Avery, Colin MacLeod and Maclyn McCarty working at the Rockefeller University, United States, continued the work of Frederick Griffith to identify the transferring principle and found that it is not protein as widely believed, but deoxyribonucleic acid (DNA). Their result pointed to the conclusion that DNA is the carrier of genetic information.

A book by a physicist that triggered a transformation in biology

The insights of brilliant brains engaged in fundamental inquiry have opened the way for major scientific discoveries and technological innovations. In 1944, the Austrian theoretical physicist Erwin Schrodinger, one of the founders of quantum mechanics, published a book titled “What is life? The physical aspect of the living cell “. The American biologist Maurice Wilkins said he was so inspired by Schrodinger’s book and after reading it, he decided to switch from ornithology to genetics. While physicist Maurice was influenced to take up biology. Francis Crick was a physicist working on magnetic mines for the British Admiralty during the war. After reading “What is life” he thought a physicist could find treasures in biology and joined the Cavendish Laboratory in Cambridge to pursue a Ph.D.

Structure of the DNA molecule

When DNA was shown to be the molecular entity that encodes genetic information, chemists rushed to determine its structure.

The pattern formed when X-rays passing through a material cast an image on a screen, provides information about its molecular structure. In 1938, the English physicist William Astbury examined DNA using x-rays and concluded that the molecule has a helical structure. Having heard a group in the United Kingdom was attempting to unearth the structure of DNA, the American theoretical chemist, Linus Pauling, adopted Astbury’s data and proposed a model for the structure of DNA, publishing the results in the journal “Nature” in January 1953.

There was an obscure but remarkably talented person, Rosalind Franklin, pursuing x-ray diffraction studies on DNA at King’s College London. After a painstaking effort, she obtained accurate x-ray diffraction images of DNA. Her colleague, Maurice Wilkins, working in the same laboratory, passed the images to Francis Crick and James Watson at Cavendish Laboratory.

Crick and Watson were more insightful and theoretical in their approach to elucidating the structure of DNA. They, inspired by Erwin Schrodinger’s hypothesis, that the entity accounting for heredity should be an aperiodic molecular entity in cells, arrived at the double helix model, showing that Linus Pauling’s model was erroneous. The Crick – Watson model explained how DNA stores information and replicates during cell division. Their assertions were subsequently confirmed rigorously by experimentation. Crick, Watson and Wilkins received the Nobel Prize for Physiology and Medicine in 1962.

The work following the Crick – Watson model, firmly established that the DNA is a polymer string constituted of two strands made of a sugar- phosphate backbone, connected to each other by linkage nucleotide bases A, T, G, C. The base A links base T and G to C. When one strand is defined by the arrangement of bases, the complementary strand is defined. The arrangement bases store information analogously to a four-letter alphabet. Each individual in a species has a unique sequence of arrangement base pairs. The variation within the species is generally a fraction of a percent.

The Watson-Crick model also explained how the DNA molecule replicates. The two strands unwind and separate, and two complementary strands are inserted. The detailed dynamics of the replication process are not fully understood.

‘DNA is a cookbook’

DNA functions like a multiple – volume cookbook, written in a four-letter alphabet. The volumes are kept in a rack in the kitchen. The rack is the nucleus and volumes on it are the chromosomes, and the cell is the kitchen. A paragraph giving a recipe is a gene. Enzymes act as chefs, who read recipes and give instructions to cell machinery to prepare the dishes, which are proteins. The system is so complex; a complete macroscopic analogy would be impossible.

The significance of the Crick- Watson work

Until Charles Darwin proposed the idea of evolution, biology lacked a theoretical foundation. Darwin hypothesized, when organisms reproduce, the progeny inherit parental characters, but there are variations. The variants, though similar to the parents, have some new or altered characters. If these characters, originating from mutations or cross – breeding are favorable for survival in the environment, they dominate in the population, inheriting advantageous traits. Thus, random generation – to – generation, advancements of living organisms, become possible – a way of improving the design of things in a production process without a designer. Living systems store information and progeny retrieve them, when required. A bird hatched from an egg when matured, knows how to fly.

The discovery of DNA and understanding how it stores genetic information, replicates and mutates explained Darwinian evolution. A mutation is a change in the ordering of base pairs, accidentally during replication or due to external chemical or physical causes. In sexual reproduction, the offspring gets nearly half of its DNA from each parent. Consequently, the offspring does not have DNA identical to one parent. It mixes up DNA in the species. However, mutations generate new genes, driving evolution. Sexual reproduction and mutation acting in concert introduced the diversity of life on earth we see today.

Once science becomes explanatory and predictive, it opens the way for innovations. Theories of mechanics and electromagnetism formulated in the late 19th and early 20th centuries brought forth modern engineering, transforming it from an empirical craft to a scientific technological discipline. Before the discovery of DNA structure and its function, biological innovations were largely empirical. Today we have genetic engineering – genes in organisms can be manipulated. The goal of more advanced genetic engineering, referred to as synthetic biology, aims to induce major genetic changes to organisms by incorporating several genes to alter biochemical, physiological and anatomical functions. Gene technology is rapidly transforming medicine, agriculture and biotechnology. Cures have been found for diseases formerly branded incurable.

How did DNA come into existence

Life is believed to have originated in prebiotic oceans enriched with carbon and nitrogenous substances. How did DNA originate there? Today, chemists can synthesize DNA in minutes, via selective procedures, only humans can do with their knowledge. Even in a vast ocean containing trillions of times more molecular ingredients than in a test tube, a molecule as complex as DNA is most unlikely to be created by random events during the largest possible time scales of the universe. A plausible scenario would be DNA evolving from simpler self-replicating molecules such as RNA (a single strand of DNA) precursors. Unlike RNA, DNA is highly stable and good stability is necessary for the evolution of advanced forms of life.

Epigenetics

Earlier we pointed out there are two golden sayings in our culture: “Arae gathi nare” and “Jammeta wada lokuei purudha (“Hereditary characters persist” and “Habits overtake heredity “). The first is a consequence of our genetic predisposition determined by DNA and explicit genes. However, the character of an individual is also influenced by the physical, social and cultural environment. Although completely non-genetic, our children frequently follow habits we indulge in. Again, the behavior of an individual is also influenced by the physical, social and cultural environment.

The environmental factors also trigger or silence genes. The study of this important genetic effect, which does not alter the sequence of base pairs, is referred to as epigenetics. Epigenetic effects could be deleterious or beneficial. Sometimes, chronic stress causes disease, including cancer. Research suggests engagement in creative and imaginative activities, and establishes favorable epigenetic changes in the brain. Inheritance is dictated mainly by the arrangement of base pairs in DNA. Epigenetic changes involve chemical changes in DNA without altering the sequence. These alterations are erasable but allow transmission to subsequent generations.

Conclusion: World DNA day message to lawmakers

The discovery of the structure of DNA stands as one of the most significant scientific discoveries in human history. It is a lesson to all those involved in research and education, telling how great discoveries originated. It is intense curiosity, imagination and preparation rather than mere indulgence in technologies that clear the path for discovery and innovation. A society that advocates policies conducive to discoveries, also develops new technologies that follow. If we just borrow technologies from places where they originated, hoping for quick economic returns, the effort would be a gross failure. Students, determined to be the best judging from exam performance, engage in professional disciplines and perform exceptionally. Why are we short of discoveries and innovations in those disciplines? Will our lawmakers ever realize the issue? They need to wonder why we are weak in science and poor in innovation. Right policies can even reverse adverse epigenetic attributes propagating in a society!

Odds and Ends: Horse racing and the business of sports betting – IV

Published

on

by Prof. C. A. Saliya
(The fourth instalment in a five-part series on
the business of gambling, legal and illegal)

Here’s a puzzle worth thinking about. For well over a century, Sri Lankan law has treated a village card game as a criminal offence, punishable by fine or imprisonment. In that same period, it has treated betting on horse racing as a perfectly legitimate, taxable business, one the state has actively collected revenue from for generations, under a Horse Racing Betting Ordinance older than most of the country’s other gambling law. Same basic activity, risking money on an uncertain outcome, one version illegal since 1889, the other legal the entire time.

Why? Follow the money, and the class lines, back to the colonial era. Horse racing arrived in Ceylon as a pastime of the British administrative and planter class, a “sport,” played and watched at clubs and racecourses, with betting bolted on as a respectable, even sophisticated, accompaniment. Card games played by ordinary people in villages, on the other hand, were exactly the kind of activity the same colonial authorities were eager to label a vice and criminalise. It’s the same pattern we saw with casinos in Part 2: gambling done by the wealthy tends to get called a sport, a tradition, or an investment. Gambling done by everyone else tends to get called a crime.

That history matters, but the economics of horse racing betting matter just as much, because once you understand how a bookmaker actually prices a race, you understand something that applies to almost every form of sports betting on Earth, from a Colombo racecourse to a global football sportsbook.

How a bookmaker guarantees a profit

Imagine a simple race with only two horses running, and imagine, just for the sake of the maths, that both horses genuinely have an exactly 50-50 chance of winning. A perfectly fair bookmaker, offering perfectly fair odds, would price both horses at even money: bet 100 rupees, win 100 rupees plus your stake back, on either horse.

No real bookmaker does this. Instead, they’ll price both horses slightly below their true odds, say, offering odds that imply each horse has a 55 percent chance of winning, even though the true chance is only 50 percent. Add those two implied percentages together and you get 110 percent, not 100. That extra 10 percent is called the “overround,” or sometimes the “vig” (short for vigorish), and it is the bookmaker’s guaranteed margin, built directly into the prices on the board before a single horse leaves the starting gate. It doesn’t matter which horse wins. The bookmaker’s overround wins regardless, on every single race, all day, every day.

There’s a second, subtler effect that decades of studying racing data has confirmed again and again, all over the world: bettors as a group are slightly too generous to favourites and slightly too generous to long-shots. Favourites tend to win a bit more often than their odds suggest they should, meaning betting on the favourite loses you money slightly more slowly than average over the long run, while betting on the rank outsider, the 50-to-1 shot that everyone secretly dreams will come in, loses you money considerably faster than average, because the public consistently overpays for that lottery-ticket dream. Bookmakers know this. It’s baked into their pricing, and it has a name: the favourite-longshot bias.

It’s not just horses anymore

Horse racing used to be the flagship product of the entire betting industry. It still matters enormously, including here in Sri Lanka, where it remains one of the very few genuinely legal betting products, but globally, its share of the total betting market has shrunk as sports betting on football, cricket, tennis and everything else has exploded, especially since a landmark 2018 United States Supreme Court ruling opened the door to state-by-state legal sports betting across America.

The newest and, frankly, most dangerous evolution of all this is “in-play” or “live” betting, placing bets not before a match starts, but continuously, in real time, on what happens in the next five minutes: the next corner, the next wicket, the next point. Regulators studying gambling harm consistently find that in-play betting produces worse outcomes fo bettors than traditional pre-match betting, precisely because there are so many more moments to place a bet, so much less time to think between decisions, and so much more opportunity to chase a loss five minutes after you made it.

Where the skill actually is, and isn’t

Now, a confession from this column, which has spent plenty of ink over the years analysing racecards: professional handicapping, studying trainer and jockey form, course and distance records, the draw, the going, the weight a horse is carrying, is a genuinely real skill, and it can meaningfully improve your chances of picking a winner compared to a random guess. That’s not a myth. Good handicapping works, in the narrow sense that it improves your odds of identifying the horse most likely to win any given race.

But “improving your odds of picking a winner” and “beating the house edge” are two completely different things, and this is the single most important distinction in this entire series. Even the sharpest, most statistically literate handicapper in the country is still betting into odds that already have the bookmaker’s overround baked in. Skill can narrow the gap. It essentially never closes it completely over the long run, for the simple reason that the house built the gap on purpose, and prices every race to make sure it stays open.

When the “form” is fake: Virtual meetings

One genuinely strange wrinkle worth flagging here: some betting products dress themselves up in the full costume of horse racing, trainer names, jockey silks, past form lines, even fake race commentary, while actually being nothing more than a random number generator behind the scenes, deciding the winner with no horses, no trainers, and no real race involved at all; just a computer simulation.

These “virtual racing” products exist specifically to borrow the credibility that real handicapping has earned over more than a century, and apply it to something that has no skill element whatsoever, chance and chance alone. It’s worth knowing the difference, because the two products look almost identical on a betting slip, and only one of them rewards the kind of analysis this column has always tried to teach.

Are manipulations possible?

Bookmakers don’t secretly insert horses into races to beat favorites instead they simply publish odds based on form and betting demand. The real risk comes from insiders with knowledge, such as trainers or syndicates, who can exploit undervalued horses to stage betting coups. These events are rare but welldocumented, leaving a lasting mark on regulation. In the past, bookmakers were reactive, allowing coups to succeed before odds adjusted. Today, they are far more proactive, using AI systems and integrity units to detect anomalies quickly. Even so, insider coups still occur, though they are rarer and swiftly investigated. The balance has shifted: bookmakers now lose less often, but punters continue to chase “value” in overlooked horses, keeping the contest alive between house margins and human ingenuity.

Betting Coups: When the Odds Tilt

Horse racing has always carried a mystique of glamour and risk, but behind the silks and starting gates lies a business model designed to ensure bookmakers never lose. As explained earlier, the “overround”, that invisible margin built into every price, guarantees profit before the first horse even breaks stride. Yet history shows that punters, syndicates, and insiders have occasionally turned the tables, staging coups that shook the industry and exposed its vulnerabilities. Timeline of such incidents are shown in the Table.

These stories remind us that while bookmakers build their margins into every race, the human element, ambition, deception, or sheer audacity, can still disrupt the system. Today’s safeguards, from AIdriven monitoring to integrity units, make coups rarer, but not impossible. And that tension between certainty and surprise is precisely what keeps the public fascinated. Horse racing is not just about speed and stamina; it is about the eternal contest between the house edge and human ingenuity.

The road ahead for racing in Sri Lanka

Horse racing’s legal status in Sri Lanka looks set to remain intact under the new Gambling Regulatory Authority, folded alongside casinos and licensed online sports betting operators. What’s new is that offshore online platforms, which have long taken bets from Sri Lankan customers without local approval, are now—at least on paper—being brought under the same regulatory umbrella as the racecourse. Whether this shift results in genuine oversight or simply adds a licence requirement that foreign operators quietly ignore remains an open question, one to be explored in the final instalment of this series as we assess what fair, joinedup gambling regulation would truly require.

Next week:

Part 5, the final instalment, Closing the Book, on what real gambling reform would look like, and whether Sri Lanka’s new law gets us there.

When slogans meet scrutiny

An unhealthy politics still rents the finished war — and that is why society stays divided

by Mahil Dole
Senior Superintendent of
Police (Retd.)

True national stability requires a transition this country has postponed for seventeen years: from a military victory to civic reforms that penalise divisive actors and build a unified identity. Last week showed, with unusual clarity, why that transition keeps failing. It was not a failure of slogans. It was a failure of consistency. Democracy, in the narrow sense of ballots and benches, is still standing. What is unhealthy is the use to which those ballots and benches are put. An unhealthy politics does not close a war. It rents it.

Three scenes, one week

In Chavakachcheri, President Anura Kumara Dissanayake told a housing gathering that racism would not be tolerated in any form, against Sinhalese, Tamils or Muslims, in the North, South or East. He named the old kindling: heritage sites and religious places still used to ignite tension. He spoke of houses for the displaced and a stadium for children in Jaffna. Those are the right words for a head of State. A country that meant them would be doing the unglamorous work of peace: making the next generation less useful to anyone who needs a quarrel.

In Anuradhapura, on an SLPP stage, a different performance was under way. Jaffna Member of Parliament Archchuna Ramanathan referred to himself as a “Tiger” and to the elected President as a “fox”. The name of a proscribed organisation was spoken in a town that carries the memory of the sacred-city attack. Party figures who have spent years treating any mention of the LTTE as contamination were reported to have cheered. By Monday a civil-society group styling itself the “Joint Opposition” had taken a complaint to the CID. The Police confirmed receipt. Opposition voices had already raised the alarm on Sunday.

Let the record be exact, because the rumour was not. The complaint now on the CID file is that remarks on an SLPP stage, and the cheer that met them, crossed from political insult toward promotion of a banned group. The government, for its part, has said there is no room for LTTE promotion and that remembrance of the dead is another matter. Those are two different files. Mixing them is itself a kind of politics.

A third voice belonged to the same week. Professor Savitri Goonesekere spoke with the clarity that public law, when it is still a discipline and not a campaign colour, can still produce: thoughtful, articulate, addressed to the country rather than to a faction. The speech deserves the praise it has received. The caution it invites is as important as the praise. Worthy slogans, unity, an end to racism, one law for all, are easily hijacked. They are most easily hijacked by those whose own conduct is under scrutiny, and who need the language of virtue more than they need the discipline of it. A speech of that quality raises the standard. It does not lower the duty to watch who picks the slogan up next.

What an unhealthy democracy does

People vote. Governments change. Parliament sits. That is not a failed democracy in the textbook sense. It is also not a healthy one. A healthy system converts a military victory into civic rules that bind the winners as well as the defeated, and that make division expensive. An unhealthy system keeps the war useful. It farms fear. It treats identity as a turnout machine. It issues a guarantee against racism in one district and applauds a banned name in another. That practice is not a lapse of taste. It is a structural reason society remains split.

Duplicity is the method. The same platform that built a career on the defeat of terrorism can, when the arithmetic of a rally requires it, tolerate the self-description of a Tiger. The same voices that demand a ban on LTTE propaganda can discover, the following week, that a rival’s meeting is the real offence. The same guarantee against racism can be issued in the North on one day and left unenforced in the South on the next. Two standards, again — not between Colombo and an overseas capital this time, but between the microphone and the statute book.

The LTTE remains a proscribed organisation. That is law, not a mood. Remembrance of the dead is a human act and must be protected as such. Glorification of the organisation that killed them is not remembrance. A serious State draws that line once, publishes it, and applies it without regard to who is speaking and which party owns the stage. Selective outrage is not law enforcement. It is campaigning.

The same is true of the word “racism”. No President can abolish it by declaring that he will not tolerate it. The declaration is necessary. It is not sufficient. Racism in this country has rarely been only a private vice. It has been a public business model: a way to harvest fear, postpone reform, and keep a constituency enlisted after the guns fell silent. Heritage sites and religious places become kindling because someone lights them. Universities become martyr theatres because someone books the hall. A Member of Parliament can call himself a Tiger on a southern stage because someone calculated that the cheer would be louder than the cost.

Why this divides a people

Division is not produced only by the last war and not only by those who live outside the island. It is produced, week by week, by a politics that cannot address a crowd except through Sinhala, Tamil or Muslim injury. A politics of that kind is not representing a community. It is farming one. The young, who have no memory of the last bunker, inherit the quarrel instead of a country. Serving officers watch the treatment of their predecessors and the theatre of their politicians and draw a rational conclusion about what the country values. Families who lost their own to the LTTE hear “Tiger” cheered and conclude that their dead have been repriced. Families who lost their own to the State hear a pledge against racism and wait to see whether the pledge runs south as well as north.

That is how an interval is mistaken for peace. The guns are silent. The inventory is not. “Tiger” and “traitor”, “racist” and “patriot”, remain stock in trade. So long as those words pay, in applause, in airtime, in a complaint that wounds an opponent, someone will keep them in circulation. Professor Goonesekere’s warning sits exactly there. Leadership means going beyond rhetoric. The law is not written for those who already respect it. It is written for those who violate it. When violation carries no cost, the slogan itself becomes a form of impunity.

What civic reform would actually look like

The work is unglamorous, which is why it is avoided. First, equal enforcement. If the organisation is proscribed, the prohibition travels with the speaker. An SLPP stage in Anuradhapura and a commemoration in the North are not two legal systems. The CID complaint now on the file should be treated as a test of that rule, not as a trophy for whoever lodged it.

Second, an end to ethnic first-identity as an electoral method. A civic identity, Sri Lankan first, faith and language held without being turned into a passport, will not appear by exhortation. It appears when the dividend for division falls and the dividend for competence rises.

Third, a cost for lighting kindling. Heritage sites and religious places are not campaign props. Universities are not martyr calendars. Media that carry a charge must carry the correction. Records that hold an untested allegation must not shadow a working life after the allegation has failed.

Fourth, one standard for those who served the State and those who fought it. Wrongdoers on every side belong in a court, not in a diplomatic weather system and not in a rally chant. Collective punishment of a profession is not accountability. A cheer for a banned name is not unity. A slogan against racism is not a policy until it binds the speaker’s own side.

None of this requires a new brand of commission. It requires a State that stops allowing division to be a career. South Africa’s imperfect bargain at least tried to bind both sides inside one process. Colombia wrote one jurisdiction for guerrillas, paramilitaries and State forces. We have preferred two international ledgers and a third, domestic one on which the war is rented out by the evening. Last week’s scenes, a guarantee in Chavakachcheri, a cheer in Anuradhapura, a serious speech that must not be stolen, are not opposites. They are the same unfinished settlement, spoken in three registers.

The President’s sentence should be kept, and then made expensive to break. Professor Goonesekere’s standard should be kept, and then applied to those who clap for it. Racism will not be defeated by a rally, and a proscribed organisation will not be dissolved by a complaint. They will be reduced only when the State, and the parties that live off the State, stop treating the finished war as inventory. True national stability is not the memory of a victory. It is the construction of a civic order that no longer needs that victory to be refought, in Anuradhapura or in Geneva, in order for someone to remain relevant.

Defend civic space upon which peace is built

Published

on

by Jehan Perera

International Peace Day was observed on 21 September. It finds Sri Lanka with a genuine achievement to record and a demanding test to meet. The UN’s theme this year was “Invest in Peace: For Everyone, Everywhere, Every Day.” It also honoured the “everyday architects of peace”—people driving local action and building a lasting peace from the ground up. In the 2026 Global Peace Index, Sri Lanka rose 30 places, from 97th to 67th among 163 countries. Over the same period, global peacefulness declined for the twelfth consecutive year to its lowest level since the index began, and South Asia suffered the sharpest regional deterioration. The test is whether the government will protect the civic space in which those architects of peace work.

Sri Lanka’s improvement is real and deserves acknowledgement. In this year’s review, issued a few weeks ago, the UN High Commissioner for Human Rights acknowledged progress in the form of action against corruption, arrests and investigations linked to political killings, enforced disappearances and the 2019 Easter Sunday attacks, and continued official denunciation of racism. A ranking, however, records conditions at a particular moment. It does not guarantee that they will last. Sustainable peace will depend on three factors. These are whether the government addresses the unresolved causes of conflict, whether it strengthens accountability for past and present abuses, and whether it protects the civic space in which peace is built from below. On the first two the record is incomplete. On the third, the draft NGO law threatens to weaken the very organisations that press for the other two.

What holds Sri Lanka back from a higher place are the same things that fed the war at home and also feed international conflict that rages elsewhere in the world. These are racism or ethnic nationalism that is narrow-focused, corruption and lawlessness. Equality, accountability and the rule of law are their remedies. The present government has committed itself to these, and is a significant improvement over governments of the recent past. But these pillars are not held up by governments alone. Peace is made in villages, workplaces and university campuses. It is made by families who insist on the truth about their disappeared, by journalists and lawyers who expose abuse, and by community organisations that bring Tamils, Muslims and Sinhalese into practical cooperation.

Unfinished Work

The UN High Commissioner’s report to the current Human Rights Council session, covering October 2025 to July 2026, shows how much remains to be done. The Prevention of Terrorism Act is still being applied, producing arbitrary arrests and long detention without charge. The report calls for a moratorium pending repeal and for the release of long-term detainees. Military-occupied land has not been released, memorialisation lacks support, and tensions over land and religious sites persist. The Batticaloa district illustrates how such problems endure. In the past three years, two Presidents, Ranil Wickremesinghe and Anura Kumara Dissanayake, have visited and instructed that the dispute over grazing land in Mailaththamadu and Mathavanai be resolved. It is a dispute between Tamil cattle farmers and outside Sinhala cultivators, and it has not been resolved. When two Presidents issue instructions and nothing changes, the fault lies in the machinery of State. An unresolved dispute does not stand still. It hardens into the next grievance.

Accountability shows the same pattern. The report documents torture and deaths in custody, and surveillance and intimidation of activists, journalists and civil society. Serious cases remain stalled for years, among them the killing of seventeen aid workers of Action Contre la Faim in Muttur two decades ago. Sharper still is the case of the Eastern University refugee camp at Vantharamoolai, where in 1990 the army took away 158 persons in a single day. They were never seen again. The camp’s officer-in-charge, Dr T. Jayasingam, later Vice Chancellor of the university, identified the officers responsible. More than three decades on, those officers have not been questioned. These cases are still remembered because families, survivors and independent witnesses have refused to let them be forgotten. Meanwhile several commissions of inquiry have completed their investigations but nothing further has happened.

What South Africa, Argentina and other post-conflict societies have found indispensable are four pillars of what is called “Transitional Justice” which are truth, accountability, reparations and non-recurrence. In Sri Lanka’s circumstances, truth means credible, independent investigation of what happened to the disappeared, and support for memorialisation. Accountability means prosecuting Muttur, Vantharamoolai and comparable cases, and removing credibly accused persons from senior office. Reparations mean compensation for victims and the return of military-held land. Non-recurrence means repealing the Prevention of Terrorism Act, releasing those held under it in the meantime, and resolving local disputes such as Mailaththamadu before delay hardens them. A country that buries its past does not escape it. The past returns in the next generation.

Civil Society

It is against this background that the draft NGO law is most troubling. The proposed legislation contains sweeping provisions for State oversight and control of civil society organisations. Among these are enforcing a licensing requirement on NGOs, which is to be renewed every three years, and severe penalties for not submitting reports on time, or for spending on emergency flood relief (for instance) when the NGOs mandate is peacebuilding (as an example) with possible sanctions including deregistration and having to shut down. Civil society groups have warned that it would confer excessive discretion over their registration and operations. Officials in Sri Lanka have abused such powers in the past. Additional power without effective checks invites further abuse. Sound regulation would have clear criteria for registration, an independent registrar and a right of appeal to the courts. What cannot be justified is a regime in which registration becomes a licence to be withheld from organisations that scrutinise policy, expose abuses or advocate for the rights of citizens.

Democracy is based on checks and balances. Those who press for accountability are part of those checks. The contradiction is plain. A government that has pledged accountability, equality and the rule of law ought not to be preparing to weaken the very organisations that press for their fulfilment. The organisations most exposed are those working on disappearances, land, memorialisation and reconciliation in the North and East, where the State’s record is weakest and the need for independent witnesses greatest. Silencing them would not remove the grievances they document. It would remove the channel through which those grievances are addressed peacefully. The government appears to be relenting, which is welcome, but a pause is not a withdrawal. The bill should be withdrawn and any replacement drafted in genuine consultation with those it would govern.

Investment in peace as called for by the UN in its International Peace Day theme implies commitment over time, with returns that come slowly. Sri Lanka’s 30-place rise on the Global Peace Index is a first dividend and nothing more. It can be built upon only if the government matches its commitments with action: withdrawing or fundamentally redrafting the NGO law, repealing or suspending the Prevention of Terrorism Act, and bringing Muttur, Vantharamoolai and Mailaththamadu to resolution. A higher place in a global index is not a certificate of success. Sri Lanka’s higher ranking is an encouraging start, but it will endure only if the space in which citizens speak, question and organise is protected. Peace is built from below, and a government that is serious about it will treat civil society as a partner rather than a threat.
