Published Precision instrument bolsters efforts to find elusive dark energy
(via sciencedaily.com) Original source Dark energy -- a mysterious force pushing the universe apart at an ever-increasing rate -- was discovered 26 years ago, and ever since, scientists have been searching for a new and exotic particle causing the expansion. Physicists combined an optical lattice with an atom interferometer to hold atoms in place for up to 70 seconds -- a record for an atom interferometer -- allowing them to more precisely test for deviations from the accepted theory of gravity that could be caused by dark energy particles such as chameleons or symmetrons. Though they detected no anomalies, they're improving the experiment to perform more sensitive tests of gravity, including whether gravity is quantized.
Published Mechanical computer relies on kirigami cubes, not electronics
(via sciencedaily.com) Original source Researchers have developed a kirigami-inspired mechanical computer that uses a complex structure of rigid, interconnected polymer cubes to store, retrieve and erase data without relying on electronic components. The system also includes a reversible feature that allows users to control when data editing is permitted and when data should be locked in place.
Published A new study highlights potential of ultrafast laser processing for next-gen devices
(via sciencedaily.com) Original source A new study uncovers the remarkable potential of ultrafast lasers that could provide innovative solutions in 2D materials processing for many technology developers such as high-speed photodetectors, flexible electronics, biohybrids, and next-generation solar cells.
Published Balancing act: Novel wearable sensors and AI transform balance assessment
(via sciencedaily.com) Original source Traditional methods to assess balance often suffer from subjectivity, aren't comprehensive enough and can't be administered remotely. They also are expensive and require specialized equipment and clinical expertise. Using wearable sensors and advanced machine learning algorithms, researchers offer a practical and cost-effective solution for capturing detailed movement data, essential for balance analysis. This approach is more accessible and can be administered remotely, which could have significant implications for health care, rehabilitation, sports science or other fields where balance assessment is important.
Published Researchers develop new training technique that aims to make AI systems less socially biased
(via sciencedaily.com) Original source Researchers have created a new, cost-effective training technique for artificial intelligence systems that aims to make them less socially biased.
Published Researchers discover new flat electronic bands, paving way for advanced quantum materials
(via sciencedaily.com) Original source Scientists predict the existence of flat electronic bands at the Fermi level, a finding that could enable new forms of quantum computing and electronic devices.
Published Next platform for brain-inspired computing
(via sciencedaily.com) Original source Computers have come so far in terms of their power and potential, rivaling and even eclipsing human brains in their ability to store and crunch data, make predictions and communicate. But there is one domain where human brains continue to dominate: energy efficiency.
Published Novel application of optical tweezers: Colorfully showing molecular energy transfer
(via sciencedaily.com) Original source Using a novel non-contact approach, a research team has successfully controlled the speed and efficiency of Forster resonance energy transfer between fluorescent molecules by varying the intensity of a laser beam.
Published Researchers engineer AI path to prevent power outages
(via sciencedaily.com) Original source Researchers developed an artificial intelligence (AI) model that could help electrical grids prevent power outages by automatically rerouting electricity in milliseconds. The approach is an early example of 'self-healing grid' technology, which uses AI to detect and repair problems such as outages autonomously and without human intervention when issues occur, such as storm-damaged power lines.
Published Controlling electronics with light: The magnetite breakthrough
(via sciencedaily.com) Original source Researchers have discovered that by shining different wavelengths (colors) of light on a material called magnetite, they can change its state, e.g. making it more or less conducive to electricity. The discovery could lead to new ways of designing new materials for electronics such as memory storage, sensors, and other devices that rely on fast and efficient material responses.

(via sciencedaily.com) Original source The international collaboration presented their first results with new data in four years, featuring a new low-energy sample of electron neutrinos and a dataset doubled in size.
Published A railroad of cells
(via sciencedaily.com) Original source Looking under the microscope, a group of cells slowly moves forward in a line, like a train on the tracks. The cells navigate through complex environments. A new approach now shows how they do this and how they interact with each other.
Published Researchers leverage shadows to model 3D scenes, including objects blocked from view
(via sciencedaily.com) Original source A new technique can model an entire 3D scene, including areas hidden from view, from just one camera image. The method relies on image shadows, which provide information about the geometry and location of hidden objects.
Published Breakthrough may clear major hurdle for quantum computers
(via sciencedaily.com) Original source The potential of quantum computers is currently thwarted by a trade-off problem. Quantum systems that can carry out complex operations are less tolerant to errors and noise, while systems that are more protected against noise are harder and slower to compute with. Now a research team has created a unique system that combats the dilemma, thus paving the way for longer computation time and more robust quantum computers.
Published Researchers film energy materials as they form
(via sciencedaily.com) Original source Shooting a movie in the lab requires special equipment. Especially when the actors are molecules -- invisible to the naked eye -- reacting with each other. 'Imagine trying to film tiny lava flows during a volcanic eruption. Your smartphone camera wouldn't be up to the job.
