Redeeming India’s Nuclear Power Promise: A Clean Energy Imperative for 2047

By
Introduction: A Nuclear Vision for Viksit Bharat@2047 As India marches toward its ambitious goal of becoming a developed nation by 2047, energy security stands as a pivotal pillar in the vision of Viksit Bharat . Amid the global climate crisis and rising energy demands, nuclear power has re-emerged as a compelling solution. India’s commitment to achieving 100 GW of nuclear power capacity by 2047 is both visionary and necessary—but achieving this requires a strategic shift in policy, participation, and international cooperation. While India’s nuclear energy sector has traditionally been a tightly controlled domain under government monopoly—primarily led by the Department of Atomic Energy (DAE) and Nuclear Power Corporation of India Limited (NPCIL) —it is now imperative to welcome private sector investments and foreign partnerships. A reformed nuclear ecosystem can unlock the full potential of atomic energy as a clean, reliable, and scalable contributor to India’s net-zero aspiration...

Surface-Enhanced Raman Spectroscopy (SERS): Applications in Nanotechnology, Biomedicine, and Environmental Analysis

By
Surface-Enhanced Raman Spectroscopy (SERS): Advancing Sensitivity and Applications Surface-Enhanced Raman Spectroscopy (SERS) is an advanced analytical technique that significantly enhances the Raman scattering of molecules when supported by nanostructured materials. This high sensitivity makes it an invaluable tool for various fields, including environmental monitoring, biomedicine, and nanotechnology. Here’s an in-depth look at SERS and its applications: 1. What is Surface-Enhanced Raman Spectroscopy (SERS)? Highly Sensitive : SERS amplifies the Raman scattering signal, allowing for the detection of even trace amounts of molecules, which would otherwise be undetectable using standard Raman spectroscopy. Nanostructured Materials : The technique uses nanostructures (such as gold or silver nanoparticles) to enhance the Raman signal, which is why it’s called "surface-enhanced." 2. Principles of Raman Spectroscopy Non-Destructive Chemical Analysis : Raman spectroscopy is widel...

CERN Collider Breakthrough: Why the Universe Prefers Matter Over Antimatter

By
Introduction: A Universe Built on Bias? In a groundbreaking discovery at CERN, scientists have finally found concrete evidence that the laws of physics differ for matter and antimatter . This observation could solve one of the most perplexing mysteries in cosmology — why our universe is made almost entirely of matter , even though the Big Bang should have produced equal amounts of matter and antimatter . This new clue comes from experiments conducted at the Large Hadron Collider (LHC) , the world’s most powerful particle accelerator, located near Geneva, Switzerland. The finding marks a pivotal advancement in the field of particle physics , with implications for the Standard Model , CP violation , and our fundamental understanding of the origin of the universe . What is Matter-Antimatter Asymmetry? At the dawn of the universe, matter and antimatter were created in equal proportions. Each particle of matter has an antimatter counterpart — with the same mass but opposite charge. Whe...

IN-SPACe CANSAT & Model Rocketry India Student Competition 2024–25: A Giant Leap for Student Innovation

By
In a remarkable step towards strengthening India’s STEM education framework, the Astronautical Society of India (ASI), in collaboration with the Indian Space Research Organisation (ISRO) and the Indian National Space Promotion and Authorization Center (IN-SPACe), has launched the IN-SPACe CANSAT and Model Rocketry India Student Competition 2024–25 . This unique competition is crafted for undergraduate students across India, providing them with an opportunity to engage in experiential learning through the design, fabrication, and launch of CANSATs—can-sized satellites—using model rocketry platforms. The event held on June 14, 2025 , in Tamkuhi Raj, Kushinagar, Uttar Pradesh , was not a full-fledged rocket launch carrying an actual payload. Instead, it served as a critical site and systems validation test in preparation for the upcoming national student competition. This test focused on ensuring the readiness of launch site infrastructure, safety protocols, telemetry systems, and track...

Anemia in India: Tackling Iron Deficiency with Cornell's AnemiaPhone Technology

By
Anemia in India: Tackling Iron Deficiency with Cornell's AnemiaPhone Technology Anemia is a major health concern in India, especially among vulnerable populations like women and children. The introduction of Cornell University's AnemiaPhone technology, now transferred to the Indian Council of Medical Research (ICMR) , promises a revolutionary solution to assess iron deficiency more efficiently. Below is a detailed explanation of anemia in India and how the Anemia Mukt Bharat strategy aims to tackle it: 1. What is Anemia? Anemia occurs when there is a low concentration of hemoglobin or a reduced number of red blood cells in the blood. This limits oxygen transport, leading to fatigue, weakness, and other health issues. 2. Prevalence of Anemia in India Adolescent Girls : 59% of adolescent girls are affected by anemia in India, which significantly impacts their overall health and development. Women (15-49 years) : 57% of women in this age group suffer from iron deficiency, maki...

🇮🇳 Indian Astronaut Returns to Space After 41 Years: Shubhanshu Shukla Aboard Axiom-4 Mission to ISS

By
In a landmark moment for India's space ambitions, Indian astronaut Shubhanshu Shukla has blasted off to the International Space Station (ISS) as part of the Axiom-4 mission , marking the country's return to human spaceflight after a 41-year hiatus . This historic launch from NASA’s Kennedy Space Center in Florida has not only reignited national pride but also officially kickstarted India’s human spaceflight programme . The mission, operated by Axiom Space , includes a four-member international crew that will spend 14 days in orbit , conducting scientific research, outreach programs, and various commercial activities. This momentous occasion places India among a select group of nations capable of sending humans into space and reflects the growing prowess of the Indian space sector . A New Chapter: Shubhanshu Shukla and India’s Astronautical Comeback The last Indian to go to space was Rakesh Sharma in 1984, aboard the Soviet spacecraft Soyuz T-11. Now, in 2025, Shubhanshu...
