A recent breakthrough demonstrated use of quantum science, blockchain, and cryptography to create truly random and secure numbers used in encryption for secure communication.
About the Technology:
- Encryption: Converts readable data into unreadable code using a “key”; only someone with the correct key can decrypt the message.
- Importance of Randomness: Secure encryption depends on unpredictable keys—predictable keys can be guessed or hacked.
- Issue with Computers: Most keys are generated using pseudo-random algorithms, which appear random but are predictable if the method is known.
About the Breakthrough Lava Lamp Method:
- Setup: 100 lava lamps placed on a wall at Cloudflare’s San Francisco office; a camera takes periodic photos of the moving blobs.
- Process: Each photo is converted into numerical data, creating a random seed to generate encryption keys.
- Why Lava Lamps? The heat-driven movement of wax blobs is unpredictable and creates unique images.
- Limitations: Movements follow physics, so not truly random. Also, the algorithm that converts images is deterministic—reproducible if known.
Quantum Random Number Generation Protocol:
- Why Quantum Physics: Subatomic particles like photons behave randomly; for example, a photon’s polarization is unknown until measured.
- How It Works: Scientists used lasers to generate entangled photons and measured them millions of times to produce random results.
- Data Conversion: The raw data (in binary) was biased, so a randomness extractor was used to generate a clean 512-bit unbiased number using a second random seed.
- Blockchain Role: Each step was recorded on blockchain for transparency, with digital fingerprints (hashes) to ensure data integrity.
- Team Involvement: National Institute of Standards and Technology (NIST), University of Colorado, and DRAND each handled separate parts to ensure decentralization and trust.
- Public Use: The final random numbers are shared via CURBy, a public distribution service.
- Significance: Though still emerging, this method shows strong potential for future ultra-secure encryption systems.

New research shows that rain can reduce ocean buoyancy and stabilize tropical waters, challenging the belief that rain always enhances mixing.
About Buoyancy:
- What is it: It is the upward force exerted by a fluid (e.g., water) on an object submerged in it.
- It determines whether an object floats, sinks, or stays suspended.
- Buoyancy in Oceans: It depends on density differences in water.
- Lighter water above → unstable → mixing happens.
- Heavier water above → stable → mixing stops.
- Buoyancy Flux: Measures changes in buoyancy at the ocean surface over time.
- Freshwater from rain → makes surface lighter → positive flux → promotes mixing.
- Heat loss → cools surface → makes water denser → negative flux → resists mixing.
Key Findings of the Study:
- Light Rain (0.2–4 mm/hr): Often leads to positive buoyancy flux → supports ocean mixing.
- Heavy Rain:
- Usually results in negative buoyancy flux → surface becomes stable.
- Caused by cold pools that enhance heat loss.
- Day vs. Night Effect:
- Night: Rain destabilizes surface → mixing increases.
- Day: Rain promotes stability → due to added heat loss from sunlight blockage.
- Geographical Insights:
- Cold Rain Zones (Western Pacific, Indian Ocean): More stabilization.
- Hot Rain Zones (Central Pacific): More prone to mixing.
Significance of the Study
- Scientific Implications:
- Refutes the general belief that rain always increases buoyancy.
- Shows rain can both stabilize or destabilize the ocean surface depending on conditions.
- Climate Relevance:
- Ocean mixing is key to heat, carbon, and nutrient cycling.
- Misreading rainfall’s role can skew climate and weather models.
- Practical Impact:
- Improves forecasting accuracy in oceanography and climate science.
- Aids in understanding the climate-ocean feedback loop more precisely.

A new study by the Wildlife Institute of India (WII) reveals that wind farms in the Thar Desert, Rajasthan, have the highest recorded bird mortality rates globally.
Bird Mortality at Wind Farms: Key Findings
- Study Details: Conducted across 3,000 sq. km in Jaisalmer, Rajasthan, covering 90 wind turbines and 272 bird species, including the critically endangered Great Indian Bustard.
- Carcass Count: 124 bird carcasses found within 150m radius of turbines.
- Annual Mortality Estimate: 4,464 birds per 1,000 sq. km, after corrections for detection gaps and scavenger interference.
- Control Sites: 28 sites (500–2,000m from turbines) found zero carcasses — indicating turbines as the direct cause.
- Reasons:
- Policy Gap: Onshore wind projects in India do not require Environmental Impact Assessments (EIAs), which weakens ecological safeguards.
India’s Wind Energy Growth:
- Current Status: India added 3.5 GW of wind power in the first half of 2025 — an 82% YoY increase.
- Total Installed Capacity: Now stands at 51.3 GW.
- Untapped Potential: Estimated at 1163.9 GW at 150 meters above ground level (National Institute of Wind Energy).
|
Comparison with Past Studies:
- 2019 Studies: Recorded just 0.47 bird deaths per turbine/year in Kutch and Davangere.
- Thar Desert Rate: 1.24 bird deaths per turbine/month — significantly higher.
- Contributing Factors:
- High bird density in Thar.
- Location along Central Asian Flyway.
- Collisions with turbine-linked power lines included in this study.
Proposed Mitigation Measures:
- Technological:
- Paint one turbine blade for visibility.
- Shut down turbines during peak migration or high-risk periods.
- Planning-Based:
- Careful Site Selection seen as most critical step.
- Use of tools like AVISTEP (Avian Sensitivity Tool for Energy Planning), which maps avian sensitivity across India.
- AVISTEP ranks zones as low to very high sensitivity — intended as a guide for site avoidance.

The Supreme Court of India has reserved its judgment (i.e. final decision is pending) in a set of petitions challenging the age-related eligibility criteria under the Surrogacy (Regulation) Act, 2021.
These cases involve couples who had initiated the surrogacy process prior to the enactment of the law on January 25, 2022, but are now disqualified due to the new age limits.
About the Surrogacy (Regulation) Act, 2021
- Objective: To regulate surrogacy in India, prohibit commercial surrogacy, and promote ethical, altruistic surrogacy based on medical necessity.
- Scope:
Key Provisions:
- Type Permitted: Only altruistic surrogacy (unpaid surrogate mother) is allowed; commercial surrogacy is banned.
- Eligibility Criteria for Intending Couples:
- Legally married for at least 5 years.
- Woman must be 23–50 years of age; man must be 26–55 years.
- Must not have any living biological, adopted, or surrogate child.
- Eligibility for Single Women:
- Only widows or divorcees between 35–45 years are eligible.
- Unmarried women are not eligible (currently under challenge).
- Surrogate Mother Criteria:
- Must be a close relative, married, and have at least one biological child.
- Age: 25–35 years.
- Certification Requirement: A Certificate of Essentiality is required, including:
- Proof of infertility
- Court order for parentage and custody
- Insurance for the surrogate mother
- Penalties: Commercial surrogacy invites imprisonment (up to 10 years) and fines (up to ₹10 lakh).
- Regulatory Structure:
- National Surrogacy Board at the central level.
- State Surrogacy Boards at the state level.
Issues Highlighted by the Supreme Court:
- No Transitional Provision: The Act lacks a grandfather clause to protect couples who began the surrogacy process (e.g., embryo freezing) before the law came into effect in January 2022.
- Rigid Age Limits: The court questioned the fairness of disqualifying couples solely on age grounds, especially when natural pregnancies at older ages are not prohibited.
- Violation of Fundamental Rights: Petitioners argued the age restrictions violate Article 14 (equality before law) and Article 21 (right to reproductive autonomy and personal liberty).
- Exclusion of Unmarried Women: The law permits only widows or divorcees (35–45 years) to pursue surrogacy, which the court noted may be arbitrary and discriminatory.
- Law’s Intent vs. Impact: The court stressed that while the law aims to prevent commercial surrogacy, it should not unreasonably prevent genuine intending parents from having children.

The Union Culture Ministry has successfully retrieved the sacred ‘Piprahwa’ Buddhist relics, which were set to be auctioned in Hong Kong.
About the Piprahwa Relics:
-
Discovery: Unearthed in 1898 by William Claxton Peppe, a British engineer, at Piprahwa (Siddharthnagar, Uttar Pradesh), near the Nepal border.
-
Historical Significance: Identified as ancient Kapilavastu, capital of the Shakya republic, where Prince Siddhartha (Buddha) lived before renunciation.
-
Findings at the Site: A buried stupa yielded a large stone coffer containing:
- Bone fragments believed to be Buddha’s relics
- Caskets made of soapstone and crystal
- A sandstone coffer
- Over 1,800 ornaments: pearls, rubies, sapphires, gold sheets
-
Legal Custody:
- The British Crown claimed the relics under the Indian Treasure Trove Act, 1878.
- Most artifacts were transferred to the Indian Museum, Kolkata.
Stupas with Buddha’s Relics:
- After the Buddha’s death (Mahaparinirvana), his cremated relics were divided among 8 kingdoms and a Brahmin named Drona, who coordinated their distribution.
- Each recipient built a Stupa to enshrine their share of the relics, creating important pilgrimage sites and early centers of Buddhist worship.
- The 9 stupas were located in Rajagriha, Vaishali, Kapilavastu, Allakappa, Ramagrama, Vethadipa, Pava, Kushinagar, and Pippalivana.
- Emperor Ashoka (3rd century BCE) redistributed the relics from these stupas into thousands of new stupas across his empire.
- The stupa at Ramagrama is unique because it is believed to remain untouched and still holds the original relics.
- A typical early Buddhist stupa included a hemispherical mound (anda), a square railing (harmika), a central pillar (yashti) with umbrellas (chatra), and a path for circumambulation (pradakshinapatha).
| [UPSC 2023] With reference to ancient India, consider the following statements:

An 8.8 magnitude earthquake hit off Russia’s Kamchatka Peninsula, triggering 16-foot tsunamis that reached Hawaii and northern California in the US.
About Earthquakes:
- Overview: Sudden ground shaking caused by release of stored energy in Earth’s crust due to tectonic stress.
- Cause: Occurs when tectonic plates slip at fault lines where stress had built up due to friction.
- Seismic Waves: Energy travels as:
- Primary Waves (P-waves): Fastest, compressional.
- Secondary Waves (S-waves): Slower, shear motion.
- Key Terms:
- Focus (Hypocenter): Underground origin point.
- Epicenter: Surface point directly above the focus.
- Measurement:
- Magnitude: Energy released (Richter Scale, logarithmic).
- Intensity: Observed ground shaking (varies by location).
- Seismograph: Records seismic wave activity.
How Earthquakes Trigger Tsunamis?
- Underwater Epicenter: Must occur beneath oceans to displace water.
- Shallow Depth: Quakes at <70 km transfer energy more efficiently to water surface.
- Reverse Faulting: One tectonic plate pushes over another, vertically shifting the seafloor.
- Rapid Displacement: Sudden seafloor uplift/downthrust generates massive water waves.
- High Magnitude: Quakes >7.0 (especially >8.0) likely to trigger tsunamis.
About the Kamchatka Region:
- Overview: Russian Far East; borders the North Pacific Ocean.
- Tectonic Zone: Sits on the Kuril-Kamchatka Trench—Pacific Plate subducting under Okhotsk Plate at ~86 mm/year.
- Seismic Hotspot: Historical major quakes in 1841, 1923, 1952, 2006, and 2020.
- Ring of Fire: Part of the 40,000 km Pacific Ring of Fire , known for quakes and volcanoes.
- 2025 Earthquake:
- Depth:3 km (shallow)
- Impact: Triggered tsunami waves up to 16 ft—one of the strongest earthquakes since 1900.
| [UPSC 2004] Consider the following geological phenomena:
1. Development of a fault 2. Movement along a fault 3. Impact produced by a volcanic eruption 4. Folding of rocks
