A: In the Cryogenian Period (720-635 million years ago), some scientists believe the earth went through through episodes when ice covered even the tropical latitudes, and the world was called ‘snowball earth’. If the oceans were mostly frozen, it was also believed that the usual interactions between the ocean, atmosphere, sunlight, and climate patterns would...

In 1974, Antony Hewish won the physics Nobel Prize for discovering pulsars. His graduate student, Jocelyn Bell Burnell, had actually spotted the first one in the data; she’d also built parts of the telescope herself, analysed the charts, noticed the anomaly, and helped confirm that it was real. But she didn’t win the prize. At...

Every instinct tells you to lean back. You’re standing at the top of a slope that drops away beneath you like the edge of the world, and every fibre of your being screams to press your weight into the mountain behind you. To hold on. To stay safe. And that’s exactly how you fall. Something...

With rising temperatures, longer heatwaves, and a rapidly growing urban economy, cooling in India is rapidly shifting from a lifestyle choice to a basic need, driving up air-conditioner use in homes and workplaces. This surge is now a major part of cities’ power demand, in turn raising concerns about blackouts and higher emissions and about...

Genetic disorders often stem from small errors in the DNA sequence with major consequences. Many diseases like cystic fibrosis and Batten disease can be traced to changes disrupting the cell’s ability to build a complete, functional protein. One particularly common culprit is the nonsense mutation, where a single incorrect DNA letter inserts a premature stop...

The story so far: Bio-based chemicals are industrial chemicals produced using biological feedstocks like sugarcane, corn, starch, or biomass residues, often through fermentation or enzymatic processes. Examples include organic acids (such as lactic acid), bio-alcohols, solvents, surfactants, and intermediates used in plastics, cosmetics, and pharmaceuticals. Enzymes are biological catalysts widely used in detergents, food processing,...

Astronomers have observed a planetary system that challenges current planet formation theories, with a rocky planet that formed beyond the orbits of its gaseous neighbors, possibly after much of the planet-forming material had been used up. The system, observed using the European Space Agency’s Cheops space telescope, consists of four planets – two rocky and...

In 1960, when she was studying chimpanzees in Tanzania, the primatologist Jane Goodall observed one chimp strip a stick of its leaves and use it to extract termites from a mound. She telegraphed her observation to her supervisor, the paleoanthropologist Louis Leakey.  “Now we must redefine ‘tool,’ redefine ‘man’ or accept chimpanzees as human,” Leakey...

A team of physicists from various universities has teamed up with the artificial intelligence (AI) model GPT-5.2 to arrive at a new result in theoretical physics, OpenAI announced on February 13. While the result itself is obscure, although valuable to physicists working on the topic, the methods that the team and the model used to...
