Raman Effect – Background of National Science Day
In India, February 28 is celebrated every year as National Science Day. This day commemorates the announcement of the Raman Effect discovered in 1928 by the eminent Indian scientist Sir C. V. Raman.
What is the Raman Effect?
- The Raman Effect refers to the phenomenon in which a small fraction of light passing through a substance undergoes a change in its wavelength.
- In simple terms, when light interacts with molecules, some of the scattered light emerges with different energy levels, leading to new spectral lines.
- This discovery is related to the scattering of light and is considered a major breakthrough in physics.
Historical Significance
- The Raman Effect was discovered in 1928.
- In 1930, C. V. Raman became the first Indian scientist to receive the Nobel Prize in Physics.
- The discovery enhanced India’s global recognition in the field of science during the pre-independence period.

Paper-II: Current Events of State Importance and Important Government Schemes and Programs
State launches action plan on snakebite
Context: The government Published the State Action Plan for Prevention and Control of Snakebite Envenoming to tackle snakebite cases.
- Karnataka launches State Action Plan on snakebite and rabies.
- The objective is to ensure that no life is lost due to delay in treatment or lack of access to medicines.
- The Karnataka government published the State Action Plan for Prevention and Control of Snakebite Envenoming (SAPSE), becoming the first State in the country to release a comprehensive roadmap dedicated exclusively to tackling snakebite.
- The government simultaneously launched the State Action Plan for Rabies Elimination (SAPRE), reiterating its target of achieving zero human deaths due to dog-mediated rabies by 2030.
- Launched the plans under the Integrated Disease Surveillance Programme.
- Snakebite, classified by the World Health Organisation as a Neglected Tropical Disease, continues to pose a significant public health challenge.
- In India, estimates suggest around 50,000 deaths each year, besides a large number of survivors left with amputations or permanent disabilities. Public health experts have pointed out that the actual burden is likely higher, as many victims do not reach formal healthcare facilities.
- In Karnataka, recorded cases of snakebite envenoming and deaths have seen a sharp rise from 6,596 bite cases and 19 deaths in 2023 to 13,235 bite cases and 100 deaths in 2024 and 16,805 bite cases and 154 deaths in 2025.
Availability of ASV
- This follows Karnataka declaring snakebite envenoming cases and deaths notifiable under the Karnataka Epidemic Diseases Act, 2020, in February 2024.
- The State Action Plan seeks to address these gaps through strengthened surveillance, assured availability of anti-snake venom (ASV), early referral and transport, capacity building of healthcare personnel, and sustained public awareness campaigns.
- Karnataka had earlier declared snakebite a notifiable disease, mandating reporting of all cases and deaths to improve data collection and guide policy response.
- The plan aligns with the National Action Plan for Prevention and Control of Snakebite Envenoming (NAPSE), launched by the Union government in March 2024, and aims to reduce snakebite deaths and disabilities by half by 2030. It envisages coordinated action by multiple departments, including Health, Animal Husbandry, Agriculture, Forest, Panchayat Raj, Education, Labour, Finance and Home.
Key strategies
- The key strategies include promoting behavioural change through Information, Education and Communication (IEC) activities, encouraging rural communities to seek treatment at the nearest health facility instead of traditional healers, ensuring early transport of victims, prompt administration of ASV, management of complications and rehabilitation of those left disabled.
- The Health Department has identified designated snakebite treatment centres, supplied ASV stocks and circulated standard treatment guidelines. Free treatment will be provided in government facilities. Private hospitals have been directed to administer immediate life-saving care without insisting on advance payment.
- Alongside SAPSE, the State rolled out SAPRE under the National Rabies Control Programme. Rabies was declared a notifiable disease in Karnataka in December 2022. The government has mandated the availability of Anti-Rabies Vaccine (ARV) and Rabies Immunoglobulin (RIG) in all Primary Health Centres, Community Health Centres, taluk and district hospitals, with instructions to maintain adequate stocks.
- Private hospitals have also been directed to stock ARV and RIG and provide emergency treatment without demanding advance payment.
- State- and district-level joint committees have been constituted to oversee implementation, in coordination with various government departments and non-governmental organisations.
- A “Rabies-Free Cities Initiative” is being implemented in 11 major cities, including Bengaluru, Mysuru, Mangaluru and Hubballi-Dharwad. City-specific action plans focus on mass dog vaccination, dog population management, strengthened surveillance and improved waste management.

New GDP series upgrades FY26 growth to 7.6% in second advance estimates
Context: India’s economic growth is expected to touch 7.6% in the current financial year 2025-26, showed the second advance estimates of gross domestic product (GDP) based on the new and updated series released by the government. This is faster than the 7.4% predicted in the first advance estimates for 2025-26 released in January, which was based on the older series.

- The new series of data, released by Statistics Secretary and Chief Economic Adviser, has incorporated several improvements, including an updated base year of 2022-23 from the earlier 2011-12, as well as several new data sets to improve the representativeness and granularity of the data.
- The series has revised downward the growth for 2023-24 to 7.2% from the 9.2% estimated in the old series and has revised upward the growth for 2024-25 to 7.1% from the earlier estimate of 6.5%.
- According to the data, India’s nominal GDP — which is essentially the size of the economy — has been revised downward for the three years spanning 2023-26, which will have a negative impact on several fiscal ratios pegged to these numbers, such as the fiscal deficit-to-GDP ratio and the debt-to-GDP ratio.
- The government also released the GDP growth data for the third quarter of 2025-26 based on the new series, which stood at 7.8% as compared to 8.4% in the second quarter and 6.7% in the first quarter.
Growth in the current year
- According to the second advance estimates for 2025-26, the secondary sector is expected to grow at 9.5%, up from 7.3% in 2024-25. This growth is to largely be driven by the manufacturing sector, which is estimated to grow 12.5% in 2025-26 as compared to 8.3% in the previous year. The construction sector is set to grow at 6.9%, down from 7.1% over the same period.
- Notably, the primary sector is expected to see a significant slowdown, with growth expected to be 2.8% in 2025-26 as compared to 5% in the previous year. This is due to growth in the agriculture sector being expected to slow to 2.5% in 2025-26 from 4.3% in 2024-25, and in the mining and quarrying sector to 5% from 11.2% over the same period.
- The tertiary sector, comprising the services sector, is expected to see growth quicken to 8.9% in FY26, up from 8.3% in the previous year. This is a result of double-digit growth in the trade, hotels, transport and communication grouping (10.3%), and the financial, real estate, IT, and professional services grouping (10%).
Fiscal deficit at 63% of full-year target: CGA
Context: The Centre’s fiscal deficit at the end of January stood at ₹9.8 lakh crore, or 63% of the annual budget target for 2025-26, compared with 74.5% in the year-ago period, government data released showed.
- The Centre estimates the fiscal deficit during 2025-26 at 4.4% of GDP, or ₹15.58 lakh crore.
FDI rises 18% to $47.87 bn
- Foreign direct investments (FDI) in India rose 18% to $47.87 billion during April-December 2025-26, according to government data. Investments from overseas during the nine-month period of the previous fiscal stood at $40.67 billion.

a) Were the rights of the accused adequately protected during arrest and seizure?
b) Was due process strictly followed?
c) Is the focus only on punitive action, or are long-term preventive measures in place?
d) How should media publicity be handled without prejudicing the trial?
You are the Commissioner of Police responsible for ensuring that law enforcement actions are both effective and constitutionally sound.
Ethical Issues Involved
1.Public safety vs Individual rights
2.Strict law enforcement vs Human rights protection
3.Speed of action vs Fair investigation
