Published An innovative mixed light field technique for immersive projection mapping



A novel mixed light field technique that utilizes a mix of ray-controlled ambient lighting with projection mapping (PM) to obtain PM in bright surroundings has been developed by scientists. This innovative technology utilizes a novel kaleidoscope array to achieve ray-controlled lighting and a binary search algorithm for removing ambient lighting from PM targets. It provides an immersive augmented reality experience with applications in various fields.
Published Virtual reality better than video for evoking fear, spurring climate action



Depicting worst-case climate scenarios like expanding deserts and dying coral reefs may better motivate people to support environmental policies when delivered via virtual reality, according to a research team that studied how VR and message framing affect the impact of environmental advocacy communications. The study findings may help advocacy groups decide how best to frame and deliver their messages.
Published What kinds of seismic signals did Swifties send at LA concert?



Seattle may have experienced its own Swift Quake last July, but at an August 2023 concert Taylor Swift's fans in Los Angeles gave scientists a lot of shaking to ponder. After some debate, a research team concluded that it was likely the dancing and jumping motions of the audience at SoFi Stadium -- not the musical beats or reverberations of the sound system -- that generated the concert's distinct harmonic tremors.
Published Opening new doors in the VR world, literally



Recreating the action of opening doors in the virtual world requires engineering ways in which to provide the equivalent haptic feedback and steer users away from walls in the real world. A research group has done just this; developing RedirectedDoors+, which employs door robots and rotation to create a more realistic experience.
Published Straightening teeth? AI can help



A new tool will help orthodontists correctly fit braces onto teeth. Using artificial intelligence and virtual patients, the tool predicts how teeth will move, so as to ensure that braces are neither too loose nor too tight.
Published Natural history specimens have never been so accessible



Researchers have painstakingly taken computed topography (CT) scans of more than 13,000 individual specimens to create 3D images of more than half of all the world's animal groups, including mammals, fishes, amphibians and reptiles.
Published Biggest Holocene volcano eruption found by seabed survey



A detailed survey of the volcanic underwater deposits around the Kikai caldera in Japan clarified the deposition mechanisms as well as the event's magnitude. As a result, the research team found that the event 7,300 years ago was the largest volcanic eruption in the Holocene by far.
Published New detection method aims to warn of landslide tsunamis



Researchers have devised a way to remotely detect large landslides within minutes of occurrence and to quickly determine whether they are close to open water and present a tsunami hazard.
Published Angle-dependent holograms made possible by metasurfaces



Scientists unveil metasurface technology, allowing for angle-dependent holograms.
Published Plasma scientists develop computer programs that could reduce the cost of microchips and stimulate American manufacturing



Fashioned from the same element found in sand and covered by intricate patterns, microchips power smartphones, augment appliances and aid the operation of cars and airplanes. Now, scientists are developing computer simulation codes that will outperform current simulation techniques and aid the production of microchips using plasma, the electrically charged state of matter also used in fusion research. These codes could help increase the efficiency of the manufacturing process and potentially stimulate the renaissance of the chip industry in the United States.
Published Earthquake fatality measure offers new way to estimate impact on countries



A new measure that compares earthquake-related fatalities to a country's population size concludes that Ecuador, Lebanon, Haiti, Turkmenistan, Iran and Portugal have experienced the greatest impact from fatalities in the past five centuries.
Published Early-stage subduction invasion



Our planet's lithosphere is broken into several tectonic plates. Their configuration is ever-shifting, as supercontinents are assembled and broken up, and oceans form, grow, and then start to close in what is known as the Wilson cycle.
Published Why insects navigate more efficiently than robots



Engineers have studied how insects navigate, for the purpose of developing energy-efficient robots.
Published Innovations in depth from focus/defocus pave the way to more capable computer vision systems



In an image, estimating the distance between objects and the camera by using the blur in the images as clue, also known as depth from focus/defocus, is essential in computer vision. However, model-based methods fail when texture-less surfaces are present, and learning-based methods require the same camera settings during training and testing. Now, researchers have come up with an innovative strategy for depth estimation that combines the best of both the worlds to solve these limitations, extending the applicability of depth from focus/defocus.
Published Ancient rocks improve understanding of tectonic activity between earthquakes



Rocks once buried deep in ancient subduction zones -- where tectonic plates collide -- could help scientists make better predictions of how these zones behave during the years between major earthquakes, according to a research team.
Published New method to more accurately spot underground nuclear tests



A more accurate way of identifying underground nuclear tests, including those conducted in secret, has been developed.
Published A new origin story for deadly Seattle fault



The Seattle fault zone is a network of shallow faults slicing through the lowlands of Puget Sound, threatening to create damaging earthquakes for the more than four million people who live there. A new origin story, proposed in a new study, could explain the fault system's earliest history and help scientists improve hazard modeling for the densely populated region.
Published One person can supervise 'swarm' of 100 unmanned autonomous vehicles



Research involving has shown that a 'swarm' of more than 100 autonomous ground and aerial robots can be supervised by one person without subjecting the individual to an undue workload.
Published Bringing together real-world sensors and VR to improve building maintenance



A new system that brings together real-world sensing and virtual reality would make it easier for building maintenance personnel to identify and fix issues in commercial buildings that are in operation.
Published Key factors in human-made earthquakes



Researchers report that the roughness of pre-existing faults and associated stress heterogeneity in geological reservoirs play a key role for causing human-made earthquakes, so-called runaway events. The study combines novel fluid injection experiments under acoustic monitoring performed in GFZ's geomechanical laboratory with numerical modelling results.
