The Pacific Ring of Fire, the horseshoe-shaped belt of volcanoes circling the Pacific Ocean, may have played a far bigger role in shaping Earth’s past climate than previously understood. Findings show that some of the largest volcanic eruptions of the past 12,000 years, many originating from this seismically active region, align closely with major glacial…
As concerns over plastic pollution continue to grow, a 14-year-old student in Brazil has developed a sustainable alternative using materials that would otherwise be discarded. Lucas Tadao Sugahara Wernick, a student from Curitiba in the southern state of Paraná, created biodegradable food trays made from cassava peels and araucaria tree residues. Designed as a substitute…
The fossil record has a habit of reshaping ideas that once seemed settled. In the Late Cretaceous, long before the extinction of the dinosaurs, small mammals occupied a world dominated by much larger reptiles. Most left behind little more than isolated teeth and fragments of bone, making it difficult to understand how they were related…
The deep ocean has a way of turning ordinary events into unanswered questions. Far below the waves, sounds travel through water in ways that can make distant sources appear much closer or far stranger than they really are. In 1997, a powerful low-frequency noise recorded across the Pacific Ocean created one of the most unusual…
Richard Feynman’s most enduring quote was never intended as a memorable slogan. It came from his 1974 commencement address at the California Institute of Technology, where the Nobel Prize-winning physicist spoke about the principles that should guide scientific research. Among his remarks, one sentence has outlived the rest: “The first principle is that you must…
For generations, indigenous communities in Arunachal Pradesh had been using a spice in their food for its citrusy, tongue-tingling flavour. The native plant was a part of their world and that’s all they knew. But today, the small spice is helping 200 families gain a livelihood while also protecting agricultural land.On autumn mornings, residents of…

Image Credit: Getty Images Lithium is of utmost importance for modern technology. It is powering the smartphones and the huge fleet of electric vehicles. As the world is shifting towards clean energy, the demand for lithium is also increasing quickly, which is placing a huge pressure on land-based mining. However, researchers at Texas A&M University…
Left/Southern Ocean/Right/Southern Ocean on map/Image: AI Generated As the world searches for ways to remove carbon dioxide already accumulating in the atmosphere, ocean iron fertilisation (OIF) has emerged as one of the most debated climate intervention strategies. The idea is deceptively simple: adding tiny amounts of iron to iron-poor parts of the ocean stimulates the…
Communities dig water-harvesting pits to restore degraded land and improve soil moisture in the Sahel. For decades, the Sahel has symbolised environmental decline. Stretching nearly 5,900 kilometres across Africa from Senegal on the Atlantic coast to Sudan on the Red Sea, this semi-arid belt has endured recurring droughts, advancing desertification and repeated crop failures since…
