Space telescopes have traditionally faced a trade-off. They can look deeply into a small patch of the universe, revealing distant galaxies in remarkable detail, but surveying enormous areas of sky at that resolution takes time. NASA’s newly launched Nancy Grace Roman Space Telescope has been designed to change that equation. Roman lifted off from Kennedy Space Center in … [Read more...] about NASA’s Roman Space Telescope launches to map the dark universe

Imperial College London launches centre to advance surgical robotics
Robotic surgery can give surgeons greater precision and consistency, but many of the most advanced systems remain concentrated in specialist centres. A new collaboration between engineers at Imperial College London and Smith+Nephew aims to widen access by accelerating the development of technologies for robotic musculoskeletal surgery. The five-year partnership has … [Read more...] about Imperial College London launches centre to advance surgical robotics
Unexpected plasma process could reshape graphene oxide production
Some engineering breakthroughs arrive after years of carefully pursuing a single objective. Others appear almost by accident. Researchers at Texas A&M University were investigating new ways to produce hydrogen when they realised the carbon left behind wasn't simply a by-product. It was graphene oxide, one of the most widely used carbon nanomaterials in energy storage, … [Read more...] about Unexpected plasma process could reshape graphene oxide production
Origami-inspired mechanism could give robots the ability to change shape
Most robots are designed to do one job well. A wheeled robot can move quickly across smooth ground, while a four-legged machine is better suited to uneven terrain. The problem is that once a robot is built, its shape is largely fixed. Researchers at King's College London believe that could eventually change. Working with collaborators in China, the team has completed what … [Read more...] about Origami-inspired mechanism could give robots the ability to change shape
New photonic chip design brings fibre-optic performance onto silicon
Most of the world's internet traffic spends at least part of its journey travelling through optical fibre. It's fast, efficient and remarkably good at carrying light over long distances with very little signal loss. Shrinking that same performance onto a silicon chip, however, has proved far more difficult. Researchers at the California Institute of Technology (Caltech) now … [Read more...] about New photonic chip design brings fibre-optic performance onto silicon
