Oldest evidence of life on Earth has been discovered in India in a 3.4 billion-year-old layered rock shows signs of microbial life
Recent discoveries in India have unveiled biological traces that date back approximately 3.5 billion years, indicating a significantly ancient origin of life on Earth. Researchers have confirmed the presence of photosynthetic activity and intricate metabolic processes within these samples, which originated from environments close to underwater hydrothermal vents. This remarkable finding represents the oldest known biological materials found in rock formations.
Annapurni Subramaniam wins 2026 COSPAR Vikram Sarabhai Medal; marks milestone for India
In a remarkable milestone for space research, Professor Annapurni Subramaniam has been awarded the COSPAR Vikram Sarabhai Medal for 2026, marking her as the first Indian woman to receive this prestigious honor. This award recognizes her invaluable contributions to space research within developing nations. Her extensive expertise, particularly in pioneering space observatories, highlights how her work has elevated Indian space astronomy to new heights.
In 1961, British scientists stopped farming a 4-hectare barley field and left it alone; 60 years later...
A groundbreaking six-decade study reveals that passive rewilding effectively fosters the development of lush native woodlands. Through protective thorny scrub, young trees thrived, shielded from herbivores, while wind and jays ingeniously spread seeds, outlining the woodlands’ unique patterns. After fifty years, the area began to mirror the characteristics of ancient woodlands, showcasing an eco-friendly and budget-friendly approach to achieving woodland restoration objectives.
In 1968, Montana began stocking tiny shrimp to feed kokanee salmon; after they reached...
In 1968, the introduction of opossum shrimp into Montana's lakes triggered a dramatic decline in the kokanee salmon population. The shrimp fiercely competed with young salmon for essential zooplankton, resulting in a disarrayed food chain. Meanwhile, the lake trout population thrived as they turned to the remaining salmon for sustenance. This shift irrevocably changed Flathead Lake's ecological landscape and impacted its indigenous fish communities.
Mississippi landowners restored woodland for gopher tortoises; two decades later the same...
In a significant conservation effort, Mississippi wetlands welcomed the release of nearly 500 captive-reared dusky gopher frogs, marking the establishment of the sole active population in Hancock County. These frogs critically rely on gopher tortoise burrows for their survival. As private landowners take on a larger role in wildlife preservation, monitoring will be implemented to evaluate the stability of this new frog population.
Between 1969 and 1972, US released a weevil to fight musk thistle; it later attacked native thistles
A biological control initiative aimed at managing invasive thistles integrated a weevil specifically targeting musk thistle. Unfortunately, this insect extended its reach to native plant species, leading to detrimental effects on local thistles, including an endangered variety that experienced a decline in seed production. This situation underscores the critical importance of careful evaluation in invasive species control programs.
China becomes first to recover orbital rockets using two methods: How Zhuque-3 works
China's LandSpace company achieved a significant milestone in reusable rocket technology. The Zhuque-3 rocket's first stage successfully landed vertically on land after launch. This achievement demonstrates a key step towards reducing space launch costs for China. The successful recovery follows modifications after a previous mission's failure. This development supports China's expanding satellite internet ambitions and global space market competition.
Why Nataraja Statue Stands At CERN: India’s gift meets particle physics
In 2004, India presented CERN with a statue of Shiva Nataraja, a powerful symbol of cosmic creation and destruction. This statue serves as a metaphor for the essence of scientific exploration. At CERN, researchers delve into the universe's tiniest components and its earliest moments, viewing Shiva's dance as a representation of the ever-changing behavior of subatomic particles, weaving together ancient mythology and contemporary scientific knowledge.
A rotating 'garbage island' spreads over 1.6 million sq km in the Pacific with 50 kilograms of plastic per square kilometre
Between the shores of Hawaii and California floats a staggering 1.6 million square kilometers of plastic debris. This island of waste includes not just nets and ropes but also countless microplastics that pose serious threats to marine wildlife. Animals often mistake plastics for food, while others become trapped in ghost fishing gear.
