Physics news

Engineering various sources of loss provides new features for perfect light absorption

Natural and manmade physical structures all lose energy, and scientists work hard to eliminate that loss or compensate for it. Optical and photonic devices lose energy through light scattering, radiation or material absorption. In some situations, however, intentionally yet carefully designing loss in open optical devices and systems can lead to unconventional physical phenomena which inspires novel methods for optical control and engineering.

New research integrates the most effective practices for eye tracking in AR eyewear

The eyes have it. They are constantly on the move when viewing scenes in augmented reality (AR).

High average output power achieved in PAPS photocathode drive laser system

The photocathode drive laser is one of the key parts of the beam test system of the Platform of Advanced Photon Source (PAPS). Recently, the researchers from Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences obtained the output power exceeding 116 W after the main amplifier of the laser. The study was published in Optics Express.

How a state-of-the-art optics system will make the Advanced Photon Source upgrade possible

To provide X-ray beams that are both very bright and very tightly focused, an Argonne team had to create a new system of mirrors, lenses and equipment for the upgraded Advanced Photon Source.

Astronomy and Space news

Black holes found to exert a pressure on their environment

Physicists at the University of Sussex have discovered that black holes exert a pressure on their environment, in a scientific first.

Largest virtual universe free for anyone to explore

Forget about online games that promise you a "whole world" to explore. An international team of researchers has generated an entire virtual universe, and made it freely available on the cloud to everyone.

Protoplanetary disks throw out more material than gets turned into planets

When a young solar system gets going it's little more than a young star and a rotating disk of debris. Accepted thinking says that the swirling debris is swept up in planet formation. But a new study says that much of the matter in the disk could face a different fate.

Image: Volcanic trenches on Mars

This image of the young volcanic region of Elysium Planitia on Mars [10.3°N, 159.5°E] was taken on 14 April 2021 by the CaSSIS camera on the ESA-Roscosmos ExoMars Trace Gas Orbiter (TGO).

Technology news

A framework to evaluate techniques for simulating physical systems

The simulation of physical systems using computing tools can have numerous valuable applications, both in research and real-world settings. Most existing tools for simulating physical systems are based on physics theory and numerical calculations. In recent years, however, computer scientists have been trying to develop techniques that could complement these tools, which are based on the analysis of large amounts of data.

Study: AI can make better clinical decisions than humans

It's an old adage: there's no harm in getting a second opinion. But what if that second opinion could be generated by a computer, using artificial intelligence? Would it come up with better treatment recommendations than your professional proposes?

A new dataset for better augmented and mixed reality

Computer scientists at the University of California San Diego have released OpenRooms, an new, open source dataset with tools that will help users manipulate objects, materials, lighting and other properties in indoor 3D scenes to advance augmented reality and robotics.

A way to spot computer-generated faces

A small team of researchers from The State University of New York at Albany, the State University of New York at Buffalo and Keya Medical has found a common flaw in computer-generated faces by which they can be identified. The group has written a paper describing their findings and have uploaded them to the arXiv preprint server.

MAX-phase ceramics can self-heal cracks even at room temperature

Ceramics are resilient to heat and extreme environments, but they are fragile and crack easily. Recently, in a study published in Science Advances, researchers at Texas A&M University have discovered a self-healing mechanism within a type of ceramics, called MAX phases.

SSD-Insider++: A firmware-based approach to thwarting ransomware attacks

An international team of researchers is promoting the idea of using firmware to stop ransomware attacks before they can encrypt user data stored on a solid-state drive (SSD). The group presented their ideas back in 2018 at the IEEE International Conference on Distributed Computing Systems, and more recently spoke to a reporter at The Register describing their ideas.

A spoonful of sugar opens a path to longer lasting lithium sulfur batteries

Simply by adding sugar, researchers from the Monash Energy Institute have created a longer-lasting, lighter, more sustainable rival to the lithium-ion batteries that are essential for aviation, electric vehicles and submarines.

Ultra-efficient tech to power devices of tomorrow and forge sustainable energy future

Researchers from The Australian National University (ANU) have developed a system to transport data using atomically-thin semiconductors in a way that is extremely energy-efficient.

Toyota cuts production further on virus issues, chip woes

Toyota, the world's top-selling automaker, said on Friday it would further slash production in Japan and abroad because of ongoing virus disruptions and a chronic global chip shortage.

Epic seeks 'Fortnite' return on Apple's S. Korea App Store

How the terrifying evacuations from the twin towers on 9/11 helped make today's skyscrapers safer

The 2001 World Trade Center disaster was the most significant high-rise evacuation in modern times, and the harrowing experiences of the thousands of survivors who successfully escaped the twin towers have had a significant influence on building codes and standards. One legacy of the 9/11 tragedy is that today's skyscrapers can be emptied much more safely and easily in an emergency.
