Researchers from UNamur and Stanford have developed a compact, energy-efficient photonic device that steers light using twisted crystal layers. This innovation enables precise beam control, potentially revolutionizing satellite tracking, VR headsets, lasers, and quantum computing. The breakthrough uses fast simulations and machine learning to optimize design, offering a powerful new tool in light manipulation.
We’re often told it is “unscientific” or “meaningless” to ask what happened before the big bang. But a new paper by FQxI cosmologist Eugene Lim, of King's College London, UK, and astrophysicists Katy Clough, of Queen Mary University of London, UK, and Josu Aurrekoetxea, at Oxford University, UK, published in Living Reviews in Relativity, in June 2025, proposes a way forward: using complex computer simulations to numerically (rather than exactly) solve Einstein’s equations for gravity in extreme situations. The team argues that numerical relativity should be applied increasingly in cosmology to probe some of the universe’s biggest questions–including what happened before the big bang, whether we live in a multiverse, if our universe has collided with a neighboring cosmos, or whether our universe cycled through a series of bangs and crunches.
Recent research has unveiled a new mechanism that explains how carbon dioxide (CO₂) can react directly at water’s surface instead of fully dissolving first. This finding from Cambridge researchers has significant implications for our understanding of ocean acidification and chemical reactions at water interfaces.
