Researchers have developed a highly sensitive method for detecting hotspots in the environment, such as bushfires or military threats, by harnessing the focussing power of meta-optical systems.

The key to the approach is innovative lens technology thinner than a human hair, which can collect and process infrared radiation from fires and other heat sources with much improved efficiency. Crucially it does not need cryogenic cooling, unlike current sensors.

The result is sensor technology that promises to enhance devices in both the civilian and military spheres, said Dr Tuomas Haggren, lead researcher on the project.

Amidst the decline of reefs worldwide, UC Riverside scientists have launched a $1.1 million project to uncover how coral regains life-giving algae after suffering from heat stress.

An international team of scientists, led by the University of Oxford, has achieved a world-first by creating plasma "fireballs" using the Super Proton Synchrotron accelerator at CERN, Geneva, to study the stability of plasma jets emanating from blazars. The results, published today (3 November) in PNAS, could shed new light on a long-standing mystery about the Universe’s hidden magnetic fields and missing gamma rays.

A research team from Queen Mary University of London has discovered a new way to engineer thin films that can “tune” themselves much more effectively than existing materials, making them highly responsive and efficient.  

In this study, we propose a lightweight multi-wavelength network model capable of high-fidelity and efficient full-color hologram generation in both 2D and 3D display, called IncepHoloRGB.The high-speed simultaneous generation of RGB holograms at 191 frames per second (FPS) are based on Inception sampling blocks and multi-wavelength propagation module integrated with depth-traced superimposition, achieving an average structural similarity (SSIM) of 0.88 and peak signal-to-noise ratio (PSNR) of 29.00 on the DIV2K test set in reconstruction.
