CERN scientists have detected a tiny but significant difference in how matter and antimatter versions of baryons behave — offering clues to why matter dominates the universe, despite both being created equally after the Big Bang.
What is CERN’s LHCb Experiment?
- Location: At the Large Hadron Collider near Geneva, on the France–Switzerland border.
- Name: LHCb = Large Hadron Collider beauty; focuses on beauty (bottom) quarks.
- Started: Built in early 2000s; began collecting data in 2009.
- Purpose: Studies particle decay, especially of beauty quark-containing particles, to test the Standard Model and search for small anomalies.
Matter vs Antimatter – The Big Puzzle:
- Matter: Everything around us is made of it.
- Antimatter: Mirror image of matter, with opposite charges.
- Big Bang Theory: Both should have been produced equally — and destroyed each other.
- But…: Only matter remains — a mystery science is still trying to solve.
- CP Symmetry: Physics expects matter and antimatter to behave identically (Charge-Parity symmetry).
- CP Violation: When this symmetry breaks — possibly explaining why matter survived.
What did Scientists Discover?
- Focus: Lambda-b baryons and their antimatter versions.
- Finding: A small but clear CP violation — they decayed differently.
- Significance: First such discovery in baryons (previously seen only in mesons).
- Certainty: Highly reliable — only 1 in 3.5 million chance it’s random.
Why is this Important?
- Helps explain why the universe is made of matter.
- Expands discovery of CP violation to heavier particles.
- Could hint at physics beyond the Standard Model.
- Moves us closer to solving one of the universe’s biggest mysteries.

Researchers at the Raman Research Institute (RRI) found that quantum noise—usually seen as a problem—can sometimes help connect particles in a special way called entanglement, which is important for future quantum technologies.
What is Quantum Noise?
- Overview: Quantum noise refers to random disturbances that affect quantum systems, often causing loss of coherence or decoherence.
- Traditional View: It is typically seen as harmful, especially for quantum entanglement, which is crucial for quantum computing and communication.
- Entanglement Concept: It is a phenomenon where particles are so correlated that the state of one instantly affects the state of another, even at a distance.
- Effect of Decoherence: Noise-induced decoherence breaks this entanglement, thereby reducing the efficiency of quantum technologies.
Key Findings:
- Observation: Found that quantum noise can generate or revive entanglement, contrary to its typical reputation as destructive.
- Focus Area: Studied intraparticle entanglement, which involves internal properties (like spin and path) of a single particle.
- Contrast with Interparticle Entanglement: Unlike interparticle entanglement (between separate particles), intraparticle entanglement showed resilience under noise.
- Types of Noise Studied:
- Amplitude Damping: Energy loss
- Phase Damping: Loss of phase information
- Depolarizing Noise: Random changes in quantum state
- Major Observation: Under amplitude damping, intraparticle entanglement showed delayed decay, revival, and even creation from unentangled states.
- Interparticle Comparison: In contrast, interparticle entanglement exhibited steady decay with no revival or generation.
Scientific Implications:
- New Perspective: Challenges the assumption that quantum noise is purely harmful, showing it can be a resource in certain contexts.
- Technological Potential: Intraparticle entanglement is more noise-resilient, making it valuable for stable quantum devices.
- Application Areas: Findings are relevant to quantum communication, QKD (quantum key distribution), quantum computing, and quantum sensing.
- Predictive Advantage: The new formula allows precise prediction of entanglement behavior, aiding the design of robust systems.
- Platform Independence: Results are platform-agnostic, applicable to photons, neutrons, trapped ions, etc.

Researchers in China have discovered a method to curb locust swarming by manipulating their pheromones, paving the way for eco-friendly locust control.
What are Locust Swarms?
- Locusts are large grasshoppers capable of forming massive swarms, consuming up to their body weight in food daily, and travelling 150 km/day with favourable winds.
- They are highly destructive, stripping crops and threatening food security. A single swarm can consume food equivalent to the daily needs of 35,000 people.
- In India, Locust Control and Research (LC&R) oversees locust management.
- The Locust Warning Organisation (LWO), established in 1939, monitors and controls locust activity in states like Rajasthan, Gujarat, Punjab, and Haryana.
- The 2019-2022 desert locust outbreak was one of the worst in decades, devastating India, Pakistan, and East Africa, destroying over 200,000 hectares of crops.
- Despite existing control measures, locust outbreaks remain difficult to manage due to their rapid breeding capabilities.
|
About Locust Pheromones:
- Locust Behavioural Phases: Locusts exhibit two behavioural phases—solitary (non-swarming) and gregarious (swarming). The shift to gregariousness leads to swarm formation.
- Key Pheromone – 4-Vinylanisole (4VA):
- Identified in 2020 by Chinese researchers.
- Released from locusts’ hind legs after feeding, especially due to the digestion of phenylalanine (a plant compound).
- Acts as an aggregation pheromone, attracting other locusts and triggering group behaviour.
- Biochemical Pathway:
- Enzymes 4VPMT1 (dominant) and 4VPMT2 convert a precursor molecule (4VP) into 4VA.
- This process is crucial in converting solitary locusts into swarm-forming gregarious ones.
Recent Breakthrough and Its Implication:
- Discovery: Researchers at the Chinese Academy of Sciences genetically blocked 4VPMT1, preventing locusts from producing 4VA and stopping swarm formation.
- Limitations: 4NP is toxic and environmentally persistent, raising concerns for large-scale deployment.
- Strategy Proposed: RNA interference (RNAi)-based biopesticides targeting 4VPMT genes to prevent 4VA production without toxicity.
- Wider Implications:
- Marks the first pollution-free molecular approach to locust control.
- Can reduce reliance on synthetic pesticides, protect crops, and support sustainable agriculture.
- Offers a precision pest control model based on insect behavioural biochemistry.

This newscard highlights the role of Indian assistants in completing the Great Trigonometric Survey (GTS), which began in 1802 to map India’s geography.
About the Great Trigonometrical Survey (GTS):
- Launch and Objective: The GTS was a massive scientific and cartographic initiative launched in 1802 by the British to map India with unprecedented precision using trigonometry and geodesy.
- Initiator: It was conceptualised by William Lambton, a British army officer, and carried out under the East India Company.
- Purpose: It aimed to measure Earth’s curvature, create accurate maps, and support colonial administration, scientific research, and military planning.
- Survey Method: It used triangulation, involving a network of interconnected triangles built from a known baseline to calculate distances and angles over large areas.
- First Baseline: The initial baseline was measured in 1802 at St. Thomas Mount near Madras (Chennai) and extended over 2,600 km up to the Himalayas.
- Instruments Used: The survey used massive theodolites (weighing up to half a ton) and measuring chains, requiring large teams for operation and transport.
- Scientific Outcome: It led to the formulation of the Everest Spheroid, a geodetic reference model still used for mapping in South Asia.
- Duration and Leadership: Although planned to take 5 years, the project lasted nearly 70 years (until 1871) and was led by successors such as George Everest (after whom Mt. Everest was named), Andrew Scott Waugh, and James Walker.
How did the GTS led to the Mapping of India?
- First Accurate Maps: It provided scientific maps that corrected earlier errors, enabling modern geodetic frameworks for administration and infrastructure.
- Survey Range: It mapped from southern India to the Himalayas, supporting large-scale development and scientific measurement.
- Great Arc Measurement: It measured the Great Arc (Chennai to Dehradun), a significant geodetic arc that helped calculate Earth’s curvature.
- Himalayan Heights: Using triangulation data, the survey measured 79 Himalayan peaks, including Mount Everest, K2, and Kangchenjunga.
- Mount Everest Identification: In 1852, Peak XV was identified as the world’s highest mountain, later named Mount Everest in honour of George Everest.
- Latitude-Longitude System: It produced precise longitude and latitude coordinates, crucial for navigation, military logistics, and administration.
- Infrastructure Impact: Survey benchmarks supported railways, roads, canals, and earthquake studies, many of which remain relevant today.
Contribution of Indians to the GTS:
- Syed Mir Mohsin Husain: A jeweller from Arcot who repaired critical instruments and was later appointed as an instrument maker in the Surveyor General’s office.
- Radhanath Sikdar: An Indian mathematician who calculated the height of Mount Everest in 1852, confirming it as the tallest peak globally.
- Indian Field Workers: Thousands of Indian flagmen, khalasis, and labourers undertook challenging tasks like carrying heavy equipment, setting markers, and working in hazardous environments.
- Logistical Support: Indian artisans and technicians repaired, calibrated, and adapted instruments, making the project feasible under Indian conditions.
- Role of Pundits: Trained Indian “pundits” conducted secret surveys in Tibet and politically sensitive regions, where British officers were restricted.

Recently astronomers using the ATLAS telescope in Chile discovered 3I/ATLAS, the third known interstellar object and possibly the oldest comet ever detected, estimated to be over 7 billion years old.
About 3I/ATLAS:
- Discovery: It was detected on July 1, 2025, by the ATLAS telescope in Río Hurtado, Chile; confirmed interstellar due to its hyperbolic orbit and high speed (57–68 km/s).
- Significance: It is likely the oldest comet ever observed — possibly 7.6–14 billion years old, older than our 4.5-billion-year-old solar system.
- Nature: It appeared like an interstellar comet, showing signs of activity including a coma (cloud of dust/ice) and likely a tail as it nears the Sun.
- Composition: Rich in water ice and complex organic compounds; has a reddish hue indicating ancient, primordial material.
- Size: Estimated nucleus diameter is 10–30 km — larger than previous interstellar objects like 1I/ʻOumuamua and 2I/Borisov.
- Trajectory:
- Closest to Earth: ~270 million km (no threat).
- Closest to Sun: ~210 million km (Oct 29–30, 2025).
- Will exit the solar system permanently after perihelion.
- Scientific Importance:
- It offers rare opportunity to study materials from another star system.
- It can reveal clues about the formation of the Milky Way, other solar systems, and early star formation processes.
