Scientists have captured X-ray images of metal dendrites forming in microgravity for the first time, in research that could help improve manufacturing processes including casting, welding and metal 3D printing. An international research team, including scientists from the University of Manchester, conducted the experiment aboard the MASER-13 sounding rocket, which launched … [Read more...] about Rocket experiment reveals new clues about how metals are made

New model tackles hydrogen risk in aircraft
Hydrogen has long been considered a possible route to reducing carbon dioxide emissions from aviation, but storing fuel at temperatures below −250°C creates some unusual engineering problems. One of them happens inside the metal itself. Researchers at the University of Oxford have developed a model that could help engineers predict how hydrogen atoms move through metallic … [Read more...] about New model tackles hydrogen risk in aircraft
AI Can Now React to Fusion Plasma Faster Than Humans Can
Keeping a fusion plasma under control requires decisions to be made extraordinarily quickly. Inside a tokamak, disturbances can develop within milliseconds, giving human operators little chance to react before an instability begins affecting the experiment. Researchers at Princeton University and the US Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) have … [Read more...] about AI Can Now React to Fusion Plasma Faster Than Humans Can
MIT Rethinks the Qubit to Make Quantum Computers Faster and More Reliable
Quantum computers have an unusual problem: the more useful their qubits need to become, the easier it can be to disturb them. Qubits must hold quantum information for long enough to perform a calculation, but they also need to communicate with other parts of the computer quickly and reliably. Improving one of those abilities can come at the expense of the other. Researchers … [Read more...] about MIT Rethinks the Qubit to Make Quantum Computers Faster and More Reliable
Reimagining the Battery: When the Structure Becomes the Energy Store
What if an electric bicycle’s frame was also its battery? Or an aircraft wing could store some of the electricity needed to power the aircraft? A new UK research programme is exploring a future in which batteries are no longer separate objects hidden inside products, but become part of the structures themselves. Researchers at Imperial College London, Durham University and … [Read more...] about Reimagining the Battery: When the Structure Becomes the Energy Store
