More than 250 million years ago, weigeltisaurids became the first vertebrates to glide through the air, with a flight system unlike anything alive today. Long before birds, bats or even dinosaurs, a small reptile lineage became the first known vertebrates to glide through the air. Weigeltisaurids achieved flight using an unusual wing system built from entirely new bones anchored to the side of their abdomen, and new research shows these early fliers were capable, well-engineered gliders.

OpenAI claims to have found proof of Sligo scientist’s equations but tech rivals are less than impressedGeorge Gabriel Stokes made profound contributions to hydrodynamics and devised and performed many ingenious experiments in optical science. Portrait: The Royal Society Aoife KearinsMon Oct 19 2026 - 06:00 • 4 MIN READA mathematical problem is making big news, with AI companies clashing over claims by one tech giant to have found the solution to the Navier-Stokes equations. Regarded as one of trickiest puzzles of mathematics, it has Irish connection. Who was George Gabriel Stokes? George Gabriel Stokes was born in Skreen, Co Sligo, in August 1819, the son of the local Protestant minister. After schooling at home, in Dublin, and in Bristol, Stokes entered the University of Cambridge in 1837 to study mathematics. He held many of the most significant roles in 19th century science, including Lucasian Professor of Mathematics – a position previously held by Isaac Newton and later held by Stephen Hawking – and Member of Parliament for Cambridge University.

The annual Orionid meteor shower reaches its peak this week, offering the chance to see fragments of the most famous comet of all streaking across the night sky. The Orionids occur every October as Earth passes through a stream of dust left behind by Halley’s comet. As these tiny particles plunge into Earth’s atmosphere at about 66 kilometres per second, they heat the surrounding air and produce the fleeting streaks of light that we call meteors. This year, the shower is expected to reach its peak during the night of 21–22 October. Under ideal conditions, observers may see between 10 and 20 Orionid meteors per hour. Unfortunately, conditions this year are not ideal because of the presence of a bright waxing gibbous Moon. This will drown out many of the fainter meteors. Nevertheless, conditions improve during the early hours of the morning. The moon sets at about 03:00 BST, leaving a few hours of darker sky before dawn, just as Orion is climbing high into the sky. Find a safe location with as wide a view of the heavens as possible and simply watch with the naked eye. The chart shows the view looking south-east from London at midnight as 21 becomes 22 October.
