How to build a supercomputer

Last summer, three lorries travelled across the north of England hauling an unusual cargo. For 150 miles, almost 500 computers were individually wrapped in a duvet for protection. These computers once made up part of a 13-tonne supercomputer in Cheshire and were being moved to their new home at Durham University. Now, after months of painstaking installation, this second-hand supercomputer has become one of the … Continue reading How to build a supercomputer

Lego is celebrating the women of Nasa with four new figures

Four of the most incredible and pioneering women of Nasa are being celebrated with their very own Lego sets, the toy company has revealed today. You can build the Hubble Space Telescope with the ‘Mother of Hubble’ Nancy Grace Roman and develop software for space missions with Margaret Hamilton. You can also launch the International Space Station with Sally Ride, the first woman in space, … Continue reading Lego is celebrating the women of Nasa with four new figures

Earth was “born” from a giant melting pot of molten rock

Around 4.6 billion years ago, our solar system was a very different place. Instead of planets, all that was floating around the sun was clouds of gas and dust. Gravity eventually drew these clouds together into clumps, which grew into pebbles, boulders, then planet-sized rocks. Some of these smaller clumps did not make it into planets, and they still exist now, as meteorites. Studying the composition of … Continue reading Earth was “born” from a giant melting pot of molten rock

Scientists stored light as sound for the first time

We all know light travels much faster than sound. This is why when you’re caught in a storm, you see the flash of lightning much sooner than you hear the roar of the thunder. Now researchers have similarly converted a “flash of lightning into thunder” on a tiny, electronic scale by successfully storing light as sound for the first time. In particular, information from light waves was converted … Continue reading Scientists stored light as sound for the first time

Offshore wind is cheaper than nuclear power for the first time

Electricity powered by offshore wind turbines in the UK has been sold for cheaper than energy from new nuclear power for the first time, in a subsidy auction on Monday. The auction saw electricity from offshore wind sold for delivery in 2022 to 2023 for as low as £57.50 per megawatt hour. This is significantly lower than the £92.50/MWh guaranteed to Hinkley Point C, the only … Continue reading Offshore wind is cheaper than nuclear power for the first time

NASA’s Cassini spacecraft has said its final goodbye to Titan

Just a few days before it is due to plummet into the fiery atmosphere of Saturn on its self-destruct mission, Cassini has completed its final flyby of the moon Titan. The spacecraft passed Titan at 73,974 miles (119,049 kilometres) above the moon’s surface, in a symbolic ‘goodbye kiss’ flyby that will provide the spacecraft with one last nudge of gravitational energy to send it to its end. … Continue reading NASA’s Cassini spacecraft has said its final goodbye to Titan

Physicists invent the ‘flip-flop’ qubit – an entirely new form of quantum computing

A completely new design for quantum computing could make the technology much easier and cheaper to achieve, according to new research. The invention involves a radically new kind of qubit, the quantum mechanical version of a classical computer’s ‘bit’.
