AI is guzzling water and power. Here’s what we can do about it

Artificial intelligence is easily the most deceptive technological innovation of the 21st century. Its ease of use and the lightning-fast reflexes with which it spits out responses belie its enormous appetite for water and energy.ChatGPT took the world by storm when it launched in late 2023, signalling an era of intelligence demand marked by seamless, […]

How oysters turn a tiny irritant into a pearl: What really goes on inside the shell |

A pearl does not begin as something precious. It begins as a problem. Inside an oyster, a tiny particle slips in and settles where it does not belong. It might be a parasite, a rough fragment, or debris carried by water. The oyster cannot force it out and cannot escape it either. Instead of reacting […]

Scientists say a space explosion 13,000 years ago may have changed life on Earth |

For a long time, the end of the Ice Age felt like a slow fading rather than a sharp break. Mammoths vanished. Old ways of living disappeared. The climate lurched colder again, without much warning. Archaeologists and geologists have argued over the cause for decades. Some blamed hunting. Others pointed to natural climate shifts. But […]

Black holes are twisting the universe: New discovery shows Einstein was right |

Black holes are twisting the universe: New discovery shows Einstein was right |

Some discoveries arrive quietly, without fireworks or clean endings. Astronomers were watching a distant flare from a galaxy far away, the kind that appears when a star wanders too close to something it should not. The data looked strange, not wrong, just unsettled. Signals rose and fell when they normally stay steady. Over time, a […]

What lies beneath Yellowstone in Wyoming is far more complex than a supervolcano |

Yellowstone National Park sits above one of the most extensively studied volcanic systems on Earth. Beneath its forests, geyser basins and river valleys lies a vast accumulation of partially molten rock, heat and fluids that has shaped the region for more than two million years. Scientific attention has intensified as analytical techniques have improved, allowing […]

Is interstellar object 3I/ATLAS older than our Sun? Here’s what it might reveal about the origins and observations |

When astronomers first spotted a faint, fast-moving object racing through the outer Solar System in mid-2025, few expected it to challenge what we know about cosmic history. Now known as 3I/ATLAS, the object has become one of the most intriguing astronomical discoveries of the decade. Early observations suggest it did not form alongside our Sun, […]

Einstein was fascinated by this math problem because it had no solution |

There is a tendency to imagine genius as smooth and uninterrupted. As if the great thinkers moved from one insight to the next without pause. Albert Einstein does not quite fit that picture. For all his breakthroughs, he often spoke openly about mistakes, blind spots, and ideas that refused to behave. Some of those missteps […]

Astronomers identify a planet that travels through the Milky Way without orbiting the Sun |

Astronomers have signalled the discovery of a planetary body roaming the Milky Way that is not gravitationally bound to the Sun or any other star. The entity is termed a free-floating planet, a class that embraces planetary mass bodies that are travelling in interstellar space independently. These bodies do not shine in a way that […]

Fresh images of Mars show signs of relatively recent ice age

Fresh images of Mars show signs of relatively recent ice age

Image credit: European Space Agency As you travel from the middle of Mars toward its northern regions, the landscape changes dramatically. In an area called Coloe Fossae, long shallow grooves stretch across deep valleys, scattered craters, and rocky terrain: evidence that this part of Mars was once shaped by ice.According to ‘Science Daily’, these features […]
