In 1972, French scientists discovered a natural nuclear reactor in Gabon's Oklo uranium deposit. Analysis revealed less uranium-235 than expected, indicating sustained nuclear fission reactions had occurred billions of years ago. This unique geological site provides insights into ancient Earth processes and radioactive material behavior.

Fifteen years after the Fukushima disaster, escaped domestic pigs interbred with native wild boar, revealing an unusual genetic pattern. Research shows domestic pig maternal lineages accelerated genetic turnover in hybrids, with domestic genes declining faster than expected. This offers insights into domestic animal impacts on wild populations and invasive species management.

India has deployed 12 nuclear warheads for the first time, a significant shift in its nuclear posture, according to SIPRI. With a total of 190 warheads, this move signals a move towards a more operationally ready sea-based deterrent. This development occurs as global nuclear arsenals expand, with China rapidly increasing its stockpile.

Researchers are exploring the use of radioactive waste to create ultra-long-life micro-nuclear batteries for specialized devices. These batteries, unlike consumer electronics power sources, harness energy from radioactive decay to provide a weak electric current for decades. While still in early stages with engineering challenges, the concept offers a potential solution for powering hard-to-reach or dangerous applications.

A remarkable cave discovered in 1986, sealed for millions of years, thrives without sunlight. Movile Cave hosts a unique ecosystem powered by chemosynthesis, where toxic gases fuel microorganisms forming the base of a complex food web. This isolated world, devoid of external influences, offers profound insights into life's adaptability and potential for extraterrestrial exploration.

NASA is launching an innovative mission to create a lasting presence on the Moon with a new base located near the lunar south pole. This exciting venture will unfold in multiple stages, starting with robotic explorers setting up the foundation, followed by human habitation.

A tiny pinky bone unearthed in Siberia's Denisova Cave revealed a previously unknown human species, the Denisovans. This discovery revolutionised our understanding of human evolution, showing coexistence rather than just replacement. Genetic analysis confirmed Denisovans interbred with migrating modern humans, leaving traces in the DNA of people in Southeast Asia and Oceania today.

Fifty-two years ago, India detonated a nuclear device in Rajasthan's Thar desert, codenamed 'Smiling Buddha'. This event, coinciding with Buddha Purnima, marked India's entry into the nuclear club. Despite being officially termed a 'peaceful nuclear explosion', the test ignited debate and reshaped India's global standing, demonstrating scientific self-reliance and announcing strategic intent.

India's historic 1974 nuclear test at Pokhran, a moment of national pride, remains largely uncommemorated. Despite a proposal for a memorial, the site lies forgotten, though the event boosted Jaisalmer's tourism. Villagers recall the tremors and subsequent health concerns, while the nation's nuclear prowess was solidified.

Two Bell Labs astronomers, Penzias and Wilson, investigated a persistent background noise in their radio telescope. Initially believing it to be interference, their meticulous debugging efforts, including removing pigeon droppings, failed to silence the hum. This persistent signal, however, turned out to be the cosmic microwave background radiation, providing crucial evidence for the Big Bang theory.

In 1938, German chemists Otto Hahn and Fritz Strassmann made a groundbreaking discovery. Their experiments with uranium revealed barium, an element much lighter than expected. This unexpected finding challenged existing scientific laws. It led to the understanding of nuclear fission, a process that releases immense energy. This pivotal moment ushered in the atomic age and forever changed science.

An accidental discovery in 1896 by Henri Becquerel, involving fogged photographic plates exposed to uranium salts, unveiled the phenomenon of radioactivity. This unexpected finding challenged the belief in stable atoms, revealing their inherent ability to emit energy. The breakthrough paved the way for nuclear physics and has since impacted fields from medicine to power generation.

India and Pakistan possess nearly identical nuclear arsenals, yet their doctrines diverge significantly. India adheres to 'No First Use' and aims for a minimum deterrent, while Pakistan's 'Full Spectrum Deterrence' counters India's conventional strength. India is expanding its nuclear triad, focusing on survivability and reach, while Pakistan emphasises tactical nuclear weapons and flexible options, raising escalation risks.

In 1985, scientists discovered a new form of carbon, buckminsterfullerene or C60. This molecule, shaped like a soccer ball, revealed carbon's ability to form hollow cages. The discovery opened doors to nanotechnology, influencing fields like electronics and materials science. It marked a significant shift in understanding carbon bonds and nanoparticles.

South Africa's Vredefort crater, the Earth's largest proven meteorite impact site, defies the typical circular depression image. Formed 2 billion years ago, its immense initial size has been eroded, revealing a damaged core. This weathering, however, has made it a crucial geological site, offering a unique profile to study the crust's response to giant impacts.

Tragedy struck near Krishnagiri as two young men were discovered burnt to death on the roadside in separate incidents. Authorities, including the District Superintendent of Police, are on the scene, with a special team of eight inspectors formed to investigate.

Khetolai village in Rajasthan's Jaisalmer district became historically significant due to its unique geological structure, which lacked groundwater. This made the region ideal for India's Pokhran-II nuclear tests in 1998, preventing radioactive contamination. The village now draws visitors interested in India's nuclear history.
