Published Giving particle detectors a boost
(via sciencedaily.com) Original source Researchers have tested the performance of a new device that boosts particle signals.
Published Accessibility toolkit for game engine Unity
(via sciencedaily.com) Original source New work makes it easier for game developers to implement game aids for people with disabilities. The toolkit focuses on players with visual impairments.
Published Design rules and synthesis of quantum memory candidates
(via sciencedaily.com) Original source In the quest to develop quantum computers and networks, there are many components that are fundamentally different than those used today. Like a modern computer, each of these components has different constraints. However, it is currently unclear what materials can be used to construct those components for the transmission and storage of quantum information.
Published Preventing magnet meltdowns before they can start
(via sciencedaily.com) Original source High-temperature superconductor magnets have the potential to lower the costs of operating particle accelerators and enable powerful new technologies like fusion reactors. But quenches -- the sudden, destructive events wherein a part of the material loses superconductivity -- are a major barrier to their deployment. Scientists have developed an approach to prevent quenches altogether, rather than simply trying to manage them after they occur.
Published Combined microscopy technique catches light-driven polymers in the act
(via sciencedaily.com) Original source Researchers have used tip-scan high-speed atomic force microscopy combined with an optical microscope to observe light-induced deformation of azo-polymer films. The process could be followed in real time, and the film patterns were found to change with the polarization of the light source. The observations will contribute to the use of azo-polymers in applications such as optical data storage, and the approach is expected to be useful across materials science and physical chemistry.
Published Pushing the boundary on ultralow frequency gravitational waves
(via sciencedaily.com) Original source A team of physicists has developed a method to detect gravity waves with such low frequencies that they could unlock the secrets behind the early phases of mergers between supermassive black holes, the heaviest objects in the universe.
Published The role of machine learning and computer vision in Imageomics
(via sciencedaily.com) Original source A new field promises to usher in a new era of using machine learning and computer vision to tackle small and large-scale questions about the biology of organisms around the globe.
Published Method rapidly verifies that a robot will avoid collisions
(via sciencedaily.com) Original source A new safety-check technique can prove with 100 percent accuracy that a planned robot motion will not result in a collision. The method can generate a proof in seconds and does so in a way that can be easily verified by a human.
Published Researchers develop new machine learning method for modeling of chemical reactions
(via sciencedaily.com) Original source Researchers have used machine learning to create a model that simulates reactive processes in organic materials and conditions.
Published Making quantum bits fly
(via sciencedaily.com) Original source Physicists are developing a method that could enable the stable exchange of information in quantum computers. In the leading role: photons that make quantum bits 'fly'.
Published 3D reflector microchips could speed development of 6G wireless
(via sciencedaily.com) Original source Researchers have developed a semiconductor chip that will enable ever-smaller devices to operate at the higher frequencies needed for future 6G communication technology.
Published AI can speed design of health software
(via sciencedaily.com) Original source Artificial intelligence helped clinicians to accelerate the design of diabetes prevention software, a new study finds.
Published Can you tell AI-generated people from real ones?
(via sciencedaily.com) Original source If you recently had trouble figuring out if an image of a person is real or generated through artificial intelligence (AI), you're not alone. A new study found that people had more difficulty than was expected distinguishing who is a real person and who is artificially generated.
Published Using light to precisely control single-molecule devices
(via sciencedaily.com) Original source Researchers flip the switch at the nanoscale by applying light to induce bonding for single-molecule device switching.
Published New method measures the 3D position of individual atoms
(via sciencedaily.com) Original source Since more than a decade it has been possible for physicists to accurately measure the location of individual atoms to a precision of smaller than one thousandth of a millimeter using a special type of microscope. However, this method has so far only provided the x and y coordinates. Information on the vertical position of the atom -- i.e., the distance between the atom and the microscope objective -- is lacking. A new method has now been developed that can determine all three spatial coordinates of an atom with one single image.
Published Shortcut to Success: Toward fast and robust quantum control through accelerating adiabatic passage
(via sciencedaily.com) Original source Researchers achieved the acceleration of adiabatic evolution of a single spin qubit in gate-defined quantum dots. After the pulse optimization to suppress quasistatic noises, the spin flip fidelity can be as high as 97.5% in GaAs quantum dots. This work may be useful to achieve fast and high-fidelity quantum computing.
Published One way to improve a fusion reaction: Use weaknesses as strengths
(via sciencedaily.com) Original source Scientists are embracing imperfection, using less-than-ideal magnetic fields to make the plasma more manageable.

Published Network of quantum sensors boosts precision
(via sciencedaily.com) Original source Quantum sensor technology promises even more precise measurements of physical quantities. A team has now compared the signals of up to 91 quantum sensors with each other and thus successfully eliminated the noise caused by interactions with the environment. Correlation spectroscopy can be used to increase the precision of sensor networks.
