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."

Deepika Kumari leads Indian recurve archery team to dramatic World Cup gold
Shanghai (PTI): The Indian trio of Deepika Kumari, Ankita Bhakat and teenager Kumkum Mohod held their nerve in a tense shoot-off to beat home favourites China and clinch the women's recurve team gold medal at the Archery World Cup Stage 2 here on Sunday.
In a final marked by fluctuating fortunes, India edged past the home side 5-4 (28-26) in the shoot-off after the four-set regulation ended 4-4.
The victory was especially sweeter as India had earlier stunned record 10-time Olympic champions South Korea in the semifinals en route to their first World Cup women's team gold since 2021.
Deepika, who was also part of India's World Cup-winning teams in Guatemala City and Paris in 2021, now has seven World Cup team gold medals to her name since 2010.
It was also the Indian women recurve team's first World Cup medal in three years, its previous podium finish coming in Stage 4 in Paris in 2023 where Ankita was a member of the winning team.
India's campaign in Shanghai has thus already yielded two medals after compound archer Sahil Jadhav opened the country's account, securing a bronze on Saturday.
India also remained in contention for another podium finish later in the day with recurve archer Simranjeet Kaur set to compete in the semifinals. She is a win away from her maiden individual World Cup medal.
Travelling without a full-time national coach amid the continuing impasse over appointments, it was the vastly experienced Deepika who led from the front, constantly motivating her teammates during breaks and changeovers.
Prafull Dange, who was the designated women's recurve coach after his ward Kumkum topped the national trials, largely remained in the background as Deepika guided the side through the pressure moments against a hostile home crowd and vocal Chinese support staff.
Against a young Chinese side comprising Zhu Jingyi, Huang Yuwei and teenage archer Yu Qi, who all made their World Cup debuts only last year, India looked in control initially but nearly let the match slip after taking the opening set (54-53).
Shooting last in the Indian order, Deepika set the tone with successive 10s as India edged the first set despite Ankita (8-8) and 17-year-old Kumkum (10-8) putting up an inconsistent show.
Deepika continued her fine rhythm in the second set with another perfect 10 as India briefly held a one-point advantage (28-27) midway through the end. But China responded strongly with two 9s and a 10 in their final three arrows of the second set to post 55.
Ankita replied with a 9, but Kumkum managed only an 8, leaving Deepika needing a 10 to level the set.
The four-time Olympian, however, slipped to a 7 as India lost the set 52-55 and China drew level at 2-2.
The hosts then moved ahead in the third set. The teams were initially tied at 56, but a review upgraded China's final arrow from 8 to 9, handing them the set 57-56 and a 4-2 lead.
India appeared on the verge of defeat in the fourth set despite Deepika rediscovering her touch with two 10s. Kumkum's final arrow landed in the 7-ring as India posted a modest 54.
China required two 10s and a 9 from their last three arrows to seal the match.
Zhu and Huang delivered perfect 10s, leaving 18-year-old Yu Qi needing a 9 for victory in front of the home crowd.
But the youngster shot an 8, allowing India a dramatic escape and forcing a shoot-off.
The Indians peaked at the right moment in the decider. Ankita opened with a 9, Kumkum followed with a superb 10, and Deepika calmly delivered a 9 when only an 8 was needed to seal the title.
