The technical knowledge of Egyptian architects once again exceeds expectations. Was Egypt’s oldest pyramid, the Step Pyramid of Djoser, built using some seriously high-tech kit? And what’s with the huge, unexplained cavity that’s been discovered in the Great Pyramid of Giza?
Meet the creatures for whom time has almost stood still. These animals give us a glimpse into what life was like millions of years ago, and show us just how resilient some groups have been to the calamitous events that have consigned others – such as the dinosaurs – to extinction.
There’s a mysterious object hurtling at one million miles per hour across the Milky Way. It’s moving so fast that it could exit the Milky Way entirely – and scientists are still trying to figure out what it is. Not quite a planet and not quite a star, so what is it?
The Proba-3 mission aims to unravel the mysteries of the Sun’s atmosphere by creating artificial eclipses on demand. But achieving this feat means teaching two spacecraft to perform a complicated dance with an unprecedented level of precision. If the mission is successful, scientists will be able to study the Sun’s corona in unprecedented detail, ushering in a new era for space observation.

To distance its science education systems from centurieslong British colonialism, India is leaning into its history and traditions—but at what cost?
The catastrophic floods that affected southern Brazil last May should serve as a warning to human societies that, despite the still widespread climate change skepticism or denial, mitigation and adaptation to cope with the ongoing climate crisis are urgently needed. The toll was 213 people killed or missing; 2.4 million people affected, including 600,000 displaced; and unprecedented losses in urban and rural infrastructure, including livestock.

Alone Tyrannosaurus rexsniffs the humid Cretaceous air, scenting a herd of Triceratops grazing beyond the tree line. As the predator scans the floodplain, its vision suddenly snaps into focus. A single Triceratops has broken off from the herd and wandered within striking distance. Standing motionless, the T. rex formulates a plan of attack, anticipating the precise angle at which it must intersect its target before the Triceratops can regain the safety of the herd. The afternoon silence is shattered as the predator crashes though the low branches at the edge of the forest in hot pursuit.
T. rex has hunted Triceratops in so many books, games and movies that the encounter has become a cliché. But did a scene like this one ever unfold in real life? Would T. rex identify its prey by vision or by smell? Would the Triceratops be warned by a loudly cracking branch or remain oblivious because it was unable to locate the source of the sound? Could T. rex plan its attack like a cat, or would it lash out indiscriminately like a shark?
