Plants glowing in the dark

 When Rama’s brother Lakshmana fell unconscious, hit by an arrow from Indrajit, the son of Ravana, Hanuman appealed to Sushena, the genius Sri Lankan physician, for intervention. Vaidya Sushena said, “Rush to Dronagiri Parvat in the Himalayas and fetch the herb, Sanjeevani. I will resuscitate the wounded instantly. As the plant emanates light all the time and glows in the dark! You will make no mistake in identification.” (Ramayana).

In 2016, the Ministry of Alternative Medicine, State of Uttarakhand, India proposed spending 250 million rupees to search for the herb. An ayurvedic adviser claimed the herb had been seen growing in the slopes of Dronagiri endowed with a unique fragrance and lights up in the night.

 Expeditions to the Himalayas have returned accompanying samples claimed to be Sanjeevani, but none glowed in the dark.

Although animals and fungi glowing in the dark exist, plants exhibiting the same quality are not found in nature. Nature may forbid the appearance of such plants in the wilderness for some unknown reason. Or perhaps an inadvertently long overdue. Yet if the laws of nature do not rule out their existence, man will someday invent them, somehow?

Starting in the early days of genetic engineering, attempts were made to modify plants to glow in the dark with little success. In 2017, the Russian chemist Zinaida Kazakova described the situation as: It can be done but may be as challenging as going to Mars. Things happen sooner than expected. The first plant to glow in the dark was engineered in 2020.

If a plant glowing evolved naturally, the trait would undoubtedly be a tremendous advantage for the species, because man certainly jumps to propagate. Presumably, the task that took a few decades for human intelligence to achieve, nature’s method of random mutations needs eons.

Recently a live herb emitting light constantly and blooming flowers luminescent at night was created artificially, making Valmiki’s imagination a reality.

 A synthetic biology startup Light Bio in the United States engineered a novel variety of flowering plants. And named it Firefly Petunia, because at night, the irradiance of flower buds resembles fireflies. After clearance from the United States Department of Agriculture, the transgenic ornamental was released for propagation (only in the United States) this year.

The phenomenon of light emission by living things is referred to as bioluminescence. Bioluminescent organisms live on land and more abundantly in the ocean. The familiar light sources, sun and fire are extremely hot. In the days before the advent of LEDs, people pondered how tender living objects emit light without getting burnt.

 The flashing lights of fireflies, familiar to us, fascinate the curious. For those reasons, all cultures have folklore and myths connected to fireflies. Later firefly curiosity inspired research revealing the science behind the mystery. Applications followed, notably around advanced medical research.

The seas around the Islands of Maldives frequently glitters at night owing to the bioluminescence of algae. In the olden days, the islanders revered and feared, considering the happening as an omen. Today the sight attracts tourists.

A species of jellyfish displays brilliant green bioluminescence. In 1961, the biochemist Osamu Shimomura found that when he extracted the active components, the luminescence appeared blue. Continuing experiments, Shimomura concluded a protein in the jellyfish, absorbs blue light and re-emits as green. Finding enabled devising a way of monitoring in real time, how cancer and virus diseases progress in living animals at the cellular level.

 Equally mysterious are the bioluminescent mushrooms and fungi.  In 1840 the English botanist George Gardner visiting Brazil was startled to see a group of boys playing with a luminous object. He identified it to be a mushroom growing at the base of coconut trees, subsequently named Neonothopanus Gardeneri to honor the discoverer. The same species occurs in Sri Lanka, growing on decaying exposed roots of coconut trees. We too as children played with it and read newspapers at night holding the mushroom.

One day, seven decades ago, the people of my ancestral village were agitated after seeing an avatar. Something as lengthy as a tall man in a thicket beside a footpath glowed at night, scaring passersby. Those days, it was normal for a man to walk along a footpath at night in the neighborhood, without a light source in hand. My father, who didn’t believe in ghosts, found the avatar to be a rotting bamboo pole. A mold (microscopic fungus) breeding on the pole caused luminance.

The phenomenon of bioluminescence intrigued humans since time immemorial is now understood as a sustained chemical reaction liberating energy, as light. Bioluminescent organisms carry two chemical substances: luciferin and luciferase. The former reacts with oxygen emitting light and the latter fastens the rate of the reaction without undergoing any change. Light emission sustains itself replenishing luciferin by biochemical synthesis. A remarkable way of converting the metabolic energy of an organism into light, generating very little heat and consuming oxygen.

Perhaps bioluminescence evolved more than 300 million years ago as a response of organisms to the danger posed by the increased oxygen in the atmosphere. In the carboniferous period, plants grew vigorously on land, releasing excessive amounts of oxygen. Bioluminescence afforded a way of eliminating oxygen without generating too much heat. Later organisms found other advantages of the process; to deter predators, communicate with their mates, and in the case of mushrooms attract insects and disperse spores.

Firefly petunia was designed by incorporating four genes from a Neonothopanus species mushroom and one gene from a fungus to the common, white-flowered petunia DNA. A strategy more involved than conventional genetic engineering, but a more advanced version termed synthetic biology.

Science examines nature – seeking explanations, correlations and generalizations and foresees innovations. Engineering turns innovative ideas derived from science into practicalities. During the past five decades, molecular biology and genetics have advanced tremendously. Synthetic biology aims to utilise knowledge gained to modify existing life forms or design new organisms, beneficial to the world, with the help of advanced instrumentation and computational facilities. Firefly petunia stands out as a step in this direction readily appreciated by laymen.

It is a realization of an imagination written down in one of the greatest epics of all time. And of particular interest to Sri Lankans. In the East, we mix up myth and imagination and fool ourselves. Whereas in the West, imagination inspires innovation.

In the future, you will walk on streets lit by trees. These engineered trees emit carbon dioxide at night and capture it during the daytime harvesting sunlight .Net zero carbon emissions!The author was motivated to write this essay after taking care of a Firefly Petunia plant and seeing how it glows at night.

Civilizational dialogue proving a remote possibility as realpolitik rages

Published

on

Looking back over the years since the 9/11 catastrophe, it could be said that barring former Iranian President Mohammad Khatami no world political leader of note has made an earnest effort to change the nature of global political discourse for the better. Khatami won world acclaim for his pronouncement that the time is right to launch and sustain a ‘Dialogue among Civilizations’.

This was in marked contrast to US political scientist Samuel P. Huntingdon’s epochal theses, formulated in the wake of 9/11 and other global political tumults that the Post Cold War era is essentially one of conflicts among civilizations. That is, people’s identity markers, such as culture and religion, are the prime shaping forces of international conflicts.

From a Political Realism standpoint, Huntingdon’s theory may seem to have gained in credibility over the years but it is Khatami’s pronouncement that has evoked an empathetic response in the hearts and minds of publics world wide. So much so, 2001 was proclaimed by the UN General Assembly as the ‘Year of Dialogue among Civilizations’.

It could be said that the latter proclamation was an endeavour to give back to humans their essential identity of peace-makers. It was an eschewing of the position that war and conflict are central to the human condition and amounted to upholding constructive dialogue among peoples and civilizations as a path to peace.

That things have not worked out in the world in keeping with the expectations of peace makers does not in any way invalidate the thesis that peace is the essential propensity of humans.

If peace-making is seemingly ineffective it is primarily because the path to peace is narrow, tortuous and time-consuming. On the other hand, violence usually misleadingly recommends itself to the human as the more expedient, cost-effective way out of a conflictual situation. However, the ultimate cost of the latter approach is prohibitive because it brutalizes the human beyond recognition.

Some of the evidence is before our eyes. The Trump administration, for example, has, minus much forethought, unleashed what may be described as a ‘quick-fix’ war against Iran but is now finding that it is in a veritable military quagmire in West Asia. The priority for the administration now seems to be a face-saving escape strategy. Such are the costs of the war option.

However, there is no denying that much remains to be done by the world community to bring peoples and cultures together with a view to enabling them to work as one for the cause of a less dangerous world.

Meanwhile, the broad divisions in international politics continue and past political polarities are lingering to the detriment of enhanced international understanding. The East and the West and the South and the North, for instance, are continuing to work in separate collectives, more or less, and no notable efforts are being made by the international community to bring these sides together for the purpose of united constructive action that could usher greater international well being.

The recent Shanghai Cooperation Organization Summit, 2026, held in Kyrgyztan was a replication of the above broad trends but there were some statements at the forum by Indian Prime Minister Narendra Modi that deserve special scrutiny and comment.

Modi was quoted saying among other things: ‘The land of Gandhi and the land of Buddha share a single message: the path to peace!..We must move away from endless war towards an end to the war. This is essentially for the well being of humanity. A peaceful resolution to all issues at the earliest is the call of humanity, and this is India’s message.’

The above is the language of international peace and unity. It is such language that will help in building bridges among civilizations and advance the cause of world peace. Besides, it will help bring a measure of understanding between North and South.

In this regard, the Trump administration could take a leaf or more from the Modi government. Unless it makes a ‘U turn’, as it were, in the direction of peace and reconciliation it is very unlikely that the US and the world would experience any stability worth speaking of.

Right now the US is savaging the sovereignty of Venezuela. It is a question of the ‘Empire striking back’ but Venezuela is a far cry from Iran. Iran has outsmarted the US on the battle field and is in a position to influence broad trends in the world economy since it still has control over the Hormuz Straits. That is, Iran could exercise a determining influence over world oil, gas and energy prices. In short, the US consumer’s future peace of mind is very much in the hands of Iran.

Given the above backdrop it should have dawned on the US political leadership that working towards cordial relations with Iran is the most advisable option. The US, simply, has too much to lose otherwise.

Likewise, Russia too needs to take a leaf from India. It is plain to see that its invasion of Ukraine is proving totally ineffective. It has not brought any measure of peace for the Russian people. Russia is right now experiencing a rerun of its military misadventure in Afghanistan. On the other hand, sections of the peoples concerned have been victimized and even brutalized.

Accordingly, there needs to be a coming together of democratic opinion worldwide for a fresh consideration of the options facing humanity. There is a dire need for value-based politics to take the place of Realpolitik. Besides, the language of peace and humanity needs to replace current divisive discourse with its stress on polarities and antagonisms.

International organizations of the stature of the UN need to take the lead in spearheading the above initiatives. Right now the UN gives the impression of being a spent force. This columnist hopes that he would be proved wrong on this score because the UN remains the only hope of the poor and victimized. It will be in the interests of all peoples for the UN to rejuvenate itself and dedicate itself increasingly enthusiastically to the cause of international peace.

Whether it be the South or North, dynamic, visionary political leadership and direction emerges as essential. The need is for voices that would espouse peace and accord across boundaries and divisions. For South Asia, India and Pakistan have the potential to fill this lacuna.

Sri Lanka’s constitutional test: Judicial independence beyond immediate political moment

Published

on

Superior Court Complex, Colombo

by Shelton Dharmaratne

Sri Lanka has reached an important constitutional moment.

The proposed 22nd Amendment has moved beyond political debate and into the constitutional process through which its validity will be examined. That development should change the character of the national discussion.

That is understandable in a politically contested environment. But Sri Lanka should now resist reducing a question of constitutional design to a contest over political positions.

The deeper issue concerns the relationship between constitutional reform, judicial independence and public confidence in the institutions of the State.

The Supreme Court will determine the constitutional questions before it. Public commentators should therefore exercise restraint in predicting, interpreting or seeking to influence that determination. But restraint does not require silence. It requires a more rigorous discussion of the institutional principles at stake.

A narrower constitutional question than the political debate suggests

The proposed amendment principally concerns the retirement ages of judges of the Supreme Court and Court of Appeal, together with an increase in the maximum number of judges permitted on the Court of Appeal.

Under the proposal, the retirement age of Supreme Court judges would rise from 65 to 67 and that of Court of Appeal judges from 63 to 65. The maximum number of Court of Appeal judges would also increase from 19 to 24.

Other proposed changes concerning the retirement ages of judges in the lower courts arise under separate legislation. This distinction matters because the public debate has sometimes treated the wider package of judicial reform as though it formed a single constitutional proposal.

Nor should the central issue be reduced to whether retaining experienced judges is inherently good or inherently dangerous. Both propositions are too simplistic.

Sri Lanka faces a substantial burden of pending litigation, and delays in the administration of justice impose significant costs on citizens, businesses and the State. Experienced judges represent an institutional resource. Continuity, accumulated knowledge and familiarity with complex areas of law cannot always be replaced immediately.

Those are legitimate policy considerations.

But the opposing concern is equally important: judicial tenure is not merely an employment condition. It is a structural component of judicial independence.

The real question is institutional

The critical question is not whether an individual judge is capable of acting impartially. It is whether the constitutional structure provides adequate protection against circumstances in which judicial tenure could become connected, directly or indirectly, with political authority.

That is an institutional question, not an accusation against individual judges.

A judge may be entirely conscientious and independent while the institutional arrangements surrounding the judiciary nevertheless create public doubts about independence. Constitutional democracies therefore cannot depend solely on the personal integrity of office-holders. They must construct institutions capable of preserving independence even when governments, individuals and political circumstances change.

This is particularly relevant when constitutional reform concerns the tenure of serving members of the superior judiciary.

The institutional sensitivity of such a proposal should neither be exaggerated into an allegation of improper motive nor dismissed as irrelevant. The appropriate response is transparency, procedural fairness and confidence in constitutional safeguards.

Legitimate objectives do not settle constitutional questions

The government has stated that its objectives include strengthening the administration of justice, addressing delays, retaining judicial experience and increasing institutional capacity.

Those objectives deserve serious consideration. Sri Lanka needs judicial reform. Citizens waiting years for their cases to be concluded experience the justice system very differently from those discussing it in Parliament, courtrooms or universities.

A government is therefore entitled to propose reforms designed to improve judicial efficiency.

But legitimate objectives do not automatically resolve constitutional objections. The relevant question is whether the means chosen are compatible with the constitutional structure and whether sufficient safeguards exist against unintended institutional consequences.

That is precisely why constitutional scrutiny matters.

The concerns of the Bar Association of Sri Lanka (BASL) should likewise be examined without political labelling. Opposition to the proposed changes should not automatically be characterised as opposition to judicial reform or an attempt to obstruct the government. At the same time, invoking judicial independence does not place any argument beyond scrutiny.

The appropriate questions are straightforward:

Does extending judicial tenure strengthen the administration of justice?

What risks, if any, could it create for judicial independence?

Are adequate institutional safeguards in place?

Does the proposal operate prospectively, or does it affect judges already serving?

Could the same objectives be achieved by filling vacancies, increasing judicial capacity, improving court administration and strengthening case management?

These questions can be examined rationally without attributing improper motives to either side.

Judicial vacancies and institutional confidence

Recent concerns raised by the BASL regarding judicial vacancies add another dimension to the debate. The BASL has argued that vacancies in the Supreme Court contributed to the retirement of a senior Court of Appeal judge without promotion to the Supreme Court, despite vacancies having existed. It has also raised concerns regarding forthcoming judicial retirements and the need for timely consideration of appointments.

Such matters should not be treated as evidence of the motives behind the proposed amendment. They do, however, illustrate a broader principle.

Judicial independence is shaped not only by the retirement age written into the Constitution. It is also influenced by how vacancies are filled, how promotions are determined, how seniority and merit are assessed, and whether judicial officers and the public believe that institutional decisions are made according to transparent and defensible criteria.

The government has an opportunity to address these concerns constructively.

Prompt appointments based on publicly defensible principles would strengthen confidence in the judiciary irrespective of the eventual outcome of the constitutional debate.

Seniority, merit and transparent criteria

The controversy also exposes a longstanding question concerning judicial appointments.

Seniority has traditionally carried considerable weight in judicial advancement. Yet seniority alone need not be the sole measure of merit. Conversely, replacing established practices with undefined assessments of “merit” could create another institutional problem.

If governments or appointing authorities can determine which judges are sufficiently meritorious without clear and objective criteria, uncertainty itself may become a source of institutional anxiety.

Sri Lanka would therefore benefit from clearer, objective and defensible standards governing judicial appointments and promotions.

Such standards would protect judges as well as appointing authorities. They would reduce opportunities for favouritism, strengthen institutional confidence and make it harder for political actors to portray every appointment as politically motivated.

Institutional rules are stronger safeguards than assurances of good intentions.

The State is larger than any government

One principle deserves particular emphasis: a government is not the State.

Governments are temporary. The constitutional State is continuing. Political parties change, parliamentary majorities change and political priorities change. The judiciary, however, must continue to function independently of whoever occupies the government benches.

The judiciary is neither a government institution in the political sense nor an Opposition institution. It is an institution of the State whose legitimacy depends upon its independence from both.

For that reason, governments should exercise particular caution when proposing constitutional changes affecting the judiciary, even where the policy objectives are legitimate.

The stronger a government is politically, the greater its responsibility to demonstrate institutional restraint.

That is not political weakness. It is constitutional maturity.

Public confidence is a constitutional asset

The most consequential issue may ultimately be neither retirement age nor judicial capacity, but public confidence.

Courts do not possess political power in the conventional sense. Their authority rests substantially on the acceptance of their decisions as legitimate.

Citizens will sometimes disagree with judicial decisions. But where the judiciary is perceived as independent, even unpopular decisions can command respect. If judicial institutions are perceived as being shaped by political convenience, even legally sound decisions may become vulnerable to suspicion.

Constitutional reform affecting judicial tenure must therefore be evaluated not only by its immediate administrative benefits but also by its effect on institutional credibility.

A reform that produces short-term efficiency while weakening confidence in judicial independence could impose a greater long-term cost. Conversely, reform that improves efficiency while preserving independence can strengthen both justice and public trust.

The challenge is not to choose between judicial efficiency and judicial independence. It is to achieve both.

If a referendum arises …

If the constitutional process ultimately requires approval by the people at a referendum, the debate should rise above the conventional government versus Opposition contest.

The electorate should be given a clear constitutional question and sufficient information to assess it.

Citizens should understand what problem the amendment seeks to address, why the proposed mechanism is considered necessary, what institutional risks have been identified, what safeguards exist and whether alternative measures could achieve the same objectives.

A constitutional referendum deserves a higher standard of public discussion than an ordinary election campaign.

The people would not merely be choosing a political side. They would be deciding the institutional framework within which political power and judicial authority operate.

Beyond who wins

The most important question arising from the proposed Twenty-Second Amendment is therefore not simply whether the government succeeds or whether the Opposition and BASL prevail.

Nor is it ultimately whether judicial retirement ages become 67 and 65 or remain unchanged.

Those are immediate constitutional questions. The deeper issue is what Sri Lanka learns from the controversy.

If the government seeks to modernise and strengthen the justice system, that objective deserves serious consideration. If the BASL and others warn that particular reforms may affect judicial independence, those concerns deserve equally serious examination.

Neither side strengthens the country by assuming that the other is acting in bad faith.

The constitutional system is strongest when legitimate disagreements are resolved through institutions rather than political pressure.

Whatever the eventual constitutional outcome, Sri Lanka will still face the underlying challenges of judicial vacancies, case delays, institutional capacity, judicial appointments and public confidence. Those problems will not disappear with a judicial determination, nor should the national conversation end there.

Sri Lanka should instead seek a broader consensus around a fundamental proposition:

Judicial reform and judicial independence are not competing objectives.

The real challenge is to pursue reform in a manner that strengthens the judiciary without placing its independence under suspicion.

That requires sound legislation, transparent appointments, adequate resources, efficient court administration, responsible political conduct and safeguards capable of surviving changes of government.

The present controversy will eventually pass. Political arguments surrounding it will fade.

But constitutional arrangements can endure for decades.

That is why Sri Lanka must look beyond the immediate political contest.

The ultimate test is not who wins today’s constitutional argument. It is whether, when the political moment has passed, Sri Lanka has a judiciary that is more efficient, more accessible and more trusted—while remaining sufficiently independent to hold every government, including future governments, within the boundaries of the Constitution.

Farewell to a Fashion Icon

Published

Chula was very fond of The Island newspaper and kept in touch with us on a regular basis (L) / Chula: Sent us this photo for Glam Scene, just a couple of weeks ago (R)

Sri Lanka’s fashion world lost one of its brightest stars Monday morning – veteran model, actress, and elite pageant trainer Chulpadmendra “Chula” Kumarapathirana.

Her sudden demise has certainly come as a shock to many.

Chula had just completed a major event on Sunday (30th August), and was no more in the land of the living the following day (31st August).

Born in Colombo, she was an old girl of Buddhist Ladies’ College and later studied at the National Institute of Business Management, and has many awesome achievements to her credit.

In 2006, she won the “Miss Tourism Model of the World Press Award” in Tanzania.

She entered the entertainment industry, as an actress, and gained popularity through the teledrama “Wahinna Muthu Wessak.”

Chulpadmendra has been on TV, and many Sri Lankan hip-hop music videos, including “Hanthane” and “Heena Hirimal”, and has had several other minor acting jobs since then.

She hosted the Derana Miss Sri Lanka for Miss World 2008 and even participated in the reality TV show Sirasa Dancing Star.

For over 25 years Chula was active in local and international fashion and founded the Chulpadmendra Catwalk Studio to train young newcomers

She trained hundreds of models for runway, photoshoots, auditions, and international pageants.

She was known as a fierce mentor who believed in “not just learning to walk, but learning to command the runway”.

Many young models called graduating from her studio their “happiest moment.”

Chula was very fond of The Island newspaper and kept in touch with us on a regular basis.

Her last message to The Island was a ‘thank you’ note for the article ‘New benchmark in pageant industry’:

“Thank you, Ivan, for writing such a beautiful article about me. Your unwavering support, encouragement, and belief in me throughout my career mean more than words can express. I am truly grateful for your kindness and generosity.

“My heartfelt thanks also go to The Island newspaper for featuring the article. It is a great honour, and I sincerely appreciate the recognition and support.

“Thank you once again.”

In fact, just a couple weeks ago, she sent a photo of herself for our Glam Scene and that picture I publish today, as part of this story.

May she rest in peace. Our deepest condolences to her family, students, and all who loved her.
