Researchers have made a discovery that changes what we know about light and materials. They found that engineered achiral (symmetric) materials, called achiral plasmonic metasurfaces, can absorb light differently depending on the handedness of the wavefront of light. This was surprising because, for years, such materials were found to be indifferent to any optical probes and does not show such selective absorption.

Palladium, a rare metallic element, can rapidly generate water from hydrogen and oxygen. Researchers witnessed this process at the nanoscale for the first time with an electron microscope. By viewing the process with extreme precision, researchers discovered how to optimize it to generate water at a faster rate. Process could be used to generate water on-demand in arid environments, including on other planets.

Data from an international space mission is confirming decades worth of speculation about the galactic neighborhoods of supermassive black holes.

Hyperspectral imaging is a useful technique for analyzing the chemical composition of food and agricultural products. However, it is a costly and complicated procedure, which limits its practical application. A team of researchers has developed a method to reconstruct hyperspectral images from standard RGB images using deep machine learning.

Google, Microsoft and others have taken big steps towards error-free devices, hinting that quantum computers that solve real problems aren’t far away

Plankton that lived during the last glacial maximum have helped confirm the accuracy of our climate models – suggesting the predictions those models make about future El Niño events are accurate too

Coral reefs around the world are at risk of collapse due to rising temperatures and acidifying oceans, but the natural adaptability of some species may help buy time

Promising new inroads into critical DNA testing has been forecast by experts who have applied machine learning to DNA profiling. From medical diagnostics to forensic tests and national security, PCR (polymerase chain reaction) DNA profiling has revolutionised high-throughput sampling this century -- but little has changed since it was developed in the 1980s.

Scientists have explored how quantum squeezing can improve measurement precision in complex quantum systems, with potential applications in quantum sensing, imaging, and radar technologies. These findings may lead to advancements in areas like GPS accuracy and early disease detection through more sensitive biosensors.

A new hand-held scanner can generate highly detailed 3D photoacoustic images in just seconds, paving the way for their use in a clinical setting for the first time and offering the potential for earlier disease diagnosis.

Medical imaging using magnetic resonance imaging (MRI) is very time-consuming since an image has to be compiled from data from many individual measurements. Thanks to the use of machine learning, imaging is also possible with less MRI measurement data, which saves time and costs. However, the prerequisite for this is perfect images that can be used to train the AI models. Such perfect training images do not exist for certain applications, such as real-time (moving image) MRI, as such images are always somewhat blurred. An international research team has now succeeded in generating precise live MRI images of the beating heart even without such training images and with very little MRI data with the help of smartly trained neural networks. Thanks to these improvements, real-time MRI could be used more frequently in practice in the future.
