How C.V. Raman’s Discovery is Saving Millions of Lives Today
Every year on 28 February, India celebrates National Science Day. It is the day we remember Sir C. V. Raman, an Indian physicist who made a discovery in 1928 that changed the world. He received the Nobel Prize in Physics in 1930 for this work, becoming the first Asian to win that honour in science. The Government of India declared 28 February as National Science Day in 1986 to honour this achievement and to keep the spirit of scientific thinking alive in our country. This year, 2026, the theme is "Women in Science: Catalysing Viksit Bharat," reminding us that India's growth depends on every single mind, regardless of gender. But today, let us talk about something that most people do not know. The discovery Raman made while staring at the blue sea is quietly saving your life right now, inside hospitals and medical laboratories across the world.
Let us first understand what the Raman Effect actually is, in the simplest way possible. Raman noticed that when light passes through a clear material, a tiny portion of that light changes its colour slightly. Not much, just a little. In fact, only about 1 in every 10 million particles of light called photons changes. But that tiny change is enough to tell scientists exactly what a substance is made of. Think of it like a fingerprint. Just like no two people have the same fingerprint, no two molecules change light in exactly the same way. So when scientists shine a laser, which is a focused beam of light, on any material, they can read those tiny light changes like reading a name tag. This reading is called Raman Spectroscopy, and it is the most powerful identification tool science has ever created.
Now, why does this matter to a common person sitting at home? Because this technology has quietly walked into your nearest hospital and started doing things that were once considered impossible. Let us take cancer as an example. Detecting cancer early is the difference between life and death. Earlier, doctors had to remove a tissue sample, send it to a lab, and wait for days to get results. Today, Raman spectroscopy can examine living cells and tissues without cutting, without harming, without removing anything from the body. It reads the molecular fingerprint of the tissue and tells doctors immediately whether a cell is healthy or cancerous. This means faster diagnosis, less pain for the patient, and more time to begin treatment. For millions of families who have watched a loved one battle cancer, this is not just science. It is hope delivered at the speed of light.
The medical revolution does not stop at cancer. In pharmacies and drug manufacturing companies, Raman spectroscopy is used to check whether a medicine is pure and genuine. Fake medicines are a serious problem in India and across the world. People buy tablets trusting that what is written on the label is inside the tablet. Raman spectroscopy can verify this in minutes without even opening the packet. The laser passes through the packaging, reads the molecular fingerprint of the medicine inside, and confirms whether it is real or fake. This one application alone is protecting millions of people from consuming counterfeit drugs every single day.
In blood testing, in identifying kidney stones without surgery, in checking whether a wound is healing properly at a cellular level, in detecting early signs of diabetes through the skin without even taking a blood sample, Raman spectroscopy is showing up everywhere. Scientists and doctors are working on handheld Raman devices that a local doctor in a small town can use to diagnose patients on the spot, without needing expensive lab equipment or long waiting periods. In a country like India where medical infrastructure in rural areas is still developing, this could genuinely change how millions of people receive healthcare.
All of this began with one man refusing to accept a simple answer. Raman looked at the blue sea and asked why. That one question, followed by seven years of hard work, gave the world a tool that now fights cancer, catches fake medicines, and is slowly making quality healthcare reachable for every Indian, rich or poor, city or village. This National Science Day 2026, with its focus on women in science, is also a reminder that the next Raman could be a young girl sitting anywhere in this country, asking her own "why." The only thing she needs is for the world around her to stop saying "don't ask" and start saying "go find out."

Stark reality of 'Viksit Bharat': Rahul slams govt over Noida workers' protest

New Delhi (PTI): A day after the workers' protest turned violent in Noida, Congress leader Rahul Gandhi on Tuesday said what unfolded on the streets was the "final cry" of this nation's workers and said the burden of US tariff wars, global inflation and fractured supply chains has not fallen upon Prime Minister Narendra Modi's "industrialist friends" but squarely upon the daily-wage labourer.
The Leader of Opposition said he stands with every worker who is the backbone of this country, and whom the Modi government has "come to view as a burden".
"What unfolded on the streets of Noida yesterday was the final cry of this nation's workers - a voice that went unheard at every turn, a voice weary from ceaseless pleading," Gandhi said in a post in Hindi on X.
A labourer working in Noida earns a monthly wage of Rs 12,000, yet faces a monthly rent burden of Rs 4,000 to Rs 7,000, the former Congress chief said.
By the time they receive a meager annual increment of Rs 300, their landlord has already hiked the rent by Rs 500, he pointed out.
"Before their wages can catch up, this unbridled inflation strangles life, plunging them into the depths of debt- this is the stark reality of 'Viksit Bharat'," Gandhi said.
"As one female worker remarked, 'Gas prices keep rising, but our wages do not'. In the midst of this gas crisis, these individuals have likely had to purchase a single cylinder for as much as Rs 5,000 just to keep the stoves in their homes burning," Gandhi said.
This is not merely an issue confined to Noida, nor is it an issue unique to India alone, fuel prices are skyrocketing across the globe and supply chains have been disrupted due to the conflict in West Asia, he said.
"However, the burden of America's tariff wars, global inflation, and fractured supply chains has not fallen upon Modi Ji's 'industrialist friends'. The heaviest blow has landed squarely upon the daily-wage labourer - the one who must earn each day just to eat that same day," Gandhi said.
"The labourer who played no part in any war, who drafted no policies, who simply did his work. Silently. Without complaint. And what does he receive in return when he demands his rightful dues? Coercion and oppression," the Congress leader said.
Another critical issue is that the Modi government, in a hasty and unilateral move, implemented four new Labour Codes effective November 2025, thereby extending the standard workday to 12 hours, he said.
"Is the demand of a labourer, who stands and works for 12 hours every single day, yet still has to borrow money to pay his children's school fees, truly unreasonable? And is the one who systematically denies him his rights each day truly delivering 'development'?" Gandhi said.
Noting that labourers of Noida are demanding a wage of Rs 20,000, Gandhi said this is not greed, it is his right, the sole foundation of his life.
"I stand with every worker who is the backbone of this country, and whom this government has come to view as a burden," Gandhi said.
Vehicles, including police SUVs, were torched, public property vandalised, and stone-pelting reported from industrial hubs in Noida on Monday as protests by factory workers demanding a wage hike turned violent, paralysing traffic.
The Uttar Pradesh Police used mild force to disperse the agitators and later registered FIRs against two X handles, charging them with spreading rumours linked to the unrest. The state government also formed a special panel to address the crisis.
Violence was first reported in the afternoon, with sporadic stone-pelting and vandalism continuing till 5 pm. No major incidents of arson or violence were reported thereafter, officials said.
The unrest, which began in the morning, left thousands of commuters stranded on key routes leading to Delhi during peak hours. Long queues of vehicles stretching several kilometres were reported at the Delhi-Noida border, with major congestion at Sector 62, National Highway-24, Sector 63 and the Chilla border. Protesters blocked key routes, including stretches connecting Sector 62 to Sector 16 and NH-9.
Officials said a large number of workers from industrial units in Phase-2 and Sector 60 gathered to press for long-pending wage revision demands and raised slogans.
Similar protests were reported from Sector 62 and Sector 84, including at a Motherson company unit. NH-9, a key link between Delhi and western Uttar Pradesh, was also blocked.
The protests soon escalated, with some protesters torching vehicles, vandalising property and pelting stones.
Officials said workers had been mobilising support for their demands on a wage hike and better working conditions in factories over the last two days. However, it was not clear what sparked the violence during the protest.
Gautam Buddh Nagar Police Commissioner Laxmi Singh on Tuesday said that more than 300 individuals had been arrested and seven FIRs registered in connection with the workers' protest that turned violent in Noida.
