Researchers developed a fully integrated photonic processor that can perform all the key computations of a deep neural network on a photonic chip, using light. This advance could improve the speed and energy-efficiency of running intensive deep learning models for demanding applications like lidar, astronomical research, and navigation. The deep neural network models that power

A theoretical study suggests that small black holes born in the early universe may have left behind hollow planetoids and microscopic tunnels, and that we should start looking within rocks and old buildings for them. The research proposes thinking both big and small to confirm the existence of primordial black holes, suggesting that their signatures

A team of astronomers has found that Venus has never been habitable, despite decades of speculation that our closest planetary neighbor was once much more like Earth than it is today.

Using 'DNA origami' scientists have built innovative nanostructures that pave the way for advanced robotics that can deliver targeted drugs -- plus they made a tiny map of Australia and mini dinosaurs. Researchers at the University of Sydney Nano Institute have made a significant advance in the field of molecular robotics by developing custom-designed and

Researchers' new polymer strategy shifts a centuries-old engineering paradigm with a molecular design that doesn't sacrifice stretchability for stiffness. Researchers at the University of Virginia School of Engineering and Applied Science have developed a new polymer design that appears to rewrite the textbook on polymer engineering. No longer is it dogma that the stiffer a

A novel hydrogen sensor offers a promising solution for real-time hydrogen leak detection, addressing safety concerns in industrial applications. This sensor, made with nano-patterned cupric-oxide (CuO) nanowires (NWs) with voids, can detect hydrogen at extremely low concentrations with high response, recovery speed, and precision, significantly improving previous CuO-based sensors. It has the potential to enable

The increased use of a chemical compound to replace TNT in explosive devices has a damaging and long lasting effect on plants, new research has shown.

Scientists around the world rely on ocean monitoring tools to measure the effects of climate change. Researchers advanced the technology available to measure carbon dioxide in the ocean. Scientists around the world rely on ocean monitoring tools to measure the effects of climate change. Researchers at the University of Alaska Fairbanks and their industry partners

This unobtrusive, leaf-mounted sensor saves time and improves productivity by remotely monitoring the health of plants in real-time. With growing concerns over climate change and overpopulation, we urgently need to boost agricultural productivity. With the goal of creating a way to easily tell whether a plant is thriving or dying, a leaf-mounted sensor was created

A research team has found a way to make more efficient the desorption of water-adsorption polymers used in atmospheric water harvesting and desiccant air conditioning. Harvesting water from the air and decreasing humidity are crucial to realizing a more comfortable life for humanity. Water-adsorption polymers have been playing a key part in atmospheric water harvesting

A team of physics educators is focusing on a new approach to teaching quantum physics in schools. Traditional classroom teaching has tended to focus on presenting the history of the origins of quantum physics, which often poses problems for learners. Using the quantum measurement process as an example, the researchers have now published their first

An international team of researchers has made new observations of an unusual supernova, finding the most metal-poor stellar explosion ever observed.
