Published Fossil overturns more than a century of knowledge about the origin of modern birds
(via sciencedaily.com) Fossilized fragments of a skeleton, hidden within a rock the size of a grapefruit, have helped upend one of the longest-standing assumptions about the origins of modern birds.
Published A waste windfall: New process shows promise turning plastic trash into pharmaceuticals
(via sciencedaily.com) Original source Researchers have devised a method to transform post-consumer mixed plastics that wash up on beaches into a variety of valuable products.
Published Math approach may make drug discovery more effective, efficient
(via sciencedaily.com) Researchers have devised a computer-based platform for drug discovery that could make the process more effective, more efficient and less costly.
Published DNA sequence enhances understanding origins of jaws
(via sciencedaily.com) Researchers have discovered and characterized a DNA sequence found in jawed vertebrates, such as sharks and humans, but absent in jawless vertebrates, such as lampreys. This DNA is important for the shaping of the joint surfaces during embryo development.
Published Ancient superpredator got big by front-loading its growth in its youth
(via sciencedaily.com) Original source Whatcheeria, a six-foot-long salamander-like creature that lived 340 million years ago, was the T. rex of its time: the biggest, baddest predator in its habitat. A new study reveals how they grew to their 'giant' size: instead of growing slow and steady throughout their lives like many modern reptiles and amphibians, they did most of their growing when they were young.
Published A navigation system with 10 centimeter accuracy
(via sciencedaily.com) Researchers have developed an alternative positioning system that is more robust and accurate than GPS, especially in urban settings. The working prototype that demonstrated this new mobile network infrastructure achieved an accuracy of 10 centimeter. This new technology is important for the implementation of a range of location-based applications, including automated vehicles, quantum communication and next-generation mobile communication systems.
Published Exploring the possibility of extraterrestrial life living in caves
(via sciencedaily.com) For millennia, caves have served as shelters for prehistoric humans. Caves have also intrigued scholars from early Chinese naturalists to Charles Darwin. A cave ecologist has been in and out of these subterranean ecosystems, examining the unique life forms -- and unique living conditions -- that exist in Earth's many caves. But what does that suggest about caves on other planetary bodies? In two connected studies, engineers, astrophysicists, astrobiologists and astronauts lay out the research that needs to be done to get us closer to answering the old-age question about life beyond Earth.
Published All solid-state LiDAR sensor that sees 360°
(via sciencedaily.com) A research team develops a fixed LiDAR sensor that can recognize all directions simultaneously.
Published Virtual reality experiences to aid substance use disorder recovery
(via sciencedaily.com) Researchers are combining psychological principles with innovative virtual reality technology to create a new immersive therapy for people with substance use disorders.
Published Smelling in VR environment possible with new gaming technology
(via sciencedaily.com) An odor machine, so-called olfactometer, makes it possible to smell in VR environments. First up is a 'wine tasting game' where the user smells wine in a virtual wine cellar and gets points if the guess on aromas in each wine is correct. The new technology can be printed on 3D printers.
Published Video games offer the potential of 'experiential medicine'
(via sciencedaily.com) After a decade of work, scientists have developed a suite of video game interventions that improve key aspects of cognition in aging adults.
Published An AI message decoder based on bacterial growth patterns
(via sciencedaily.com) Depending on the initial conditions used, such as nutrient levels and space constraints, bacteria tend to grow in specific ways. Researchers have created a new type of encryption scheme based on how a virtual bacterial colony grows with specific initial conditions.
Published Can eyes on self-driving cars reduce accidents?
(via sciencedaily.com) Robotic eyes on autonomous vehicles could improve pedestrian safety, according to a new study. Participants played out scenarios in virtual reality (VR) and had to decide whether to cross a road in front of a moving vehicle or not. When that vehicle was fitted with robotic eyes, which either looked at the pedestrian (registering their presence) or away (not registering them), the participants were able to make safer or more efficient choices.
Published New method for comparing neural networks exposes how artificial intelligence works
(via sciencedaily.com) A team has developed a novel approach for comparing neural networks that looks within the 'black box' of artificial intelligence to help researchers understand neural network behavior. Neural networks recognize patterns in datasets; they are used everywhere in society, in applications such as virtual assistants, facial recognition systems and self-driving cars.
Published Optical rule was made to be broken
(via sciencedaily.com) Engineers find a way to identify nanophotonic materials with the potential to improve screens for virtual reality and 3D displays along with optical technologies in general.
Published City digital twins help train deep learning models to separate building facades
(via sciencedaily.com) To automatically generate data for training deep convolutional neural network models to segment building facades, researchers used a three-dimensional model and game engine to generate digital city twin synthetic training data. They found that a model trained on these data mixed with some real data was competitive with a model trained on real data alone, revealing the potential of digital twin data to improve accuracy and replace costly manually annotated real data.
Published New chip-based beam steering device lays groundwork for smaller, cheaper lidar
(via sciencedaily.com) Researchers have developed a new chip-based beam steering technology that provides a promising route to small, cost-effective and high-performance lidar systems. Lidar, which uses laser pulses to acquire 3D information about a scene or object, is used in a wide range of applications such as autonomous driving, free-space optical communications, 3D holography, biomedical sensing and virtual reality. Researchers describe their new chip-based optical phased array (OPA) that solves many of the problems that have plagued previous OPA designs.
Published Augmented reality could be the future of paper books, according to new research
(via sciencedaily.com) Augmented reality might allow printed books to make a comeback against the e-book trend, according to researchers.
Published Engineers repurpose 19th-century photography technique to make stretchy, color-changing films
(via sciencedaily.com) A new technique opens a door to manufacturing of pressure-monitoring bandages, shade-shifting fabrics, or touch-sensing robots
Published Fiddler crab eye view inspires researchers to develop novel artificial vision
(via sciencedaily.com) Artificial vision systems are implemented in motion sensing, object detection, and self-driving vehicles. However, they are not suitable for changing external environments and are limited to a hemispherical field-of-view (FOV). Addressing this issue, researchers have now developed a novel artificial vision with 360-degree FOV that can image both terrestrial and aquatic environments. The system, modeled after the eye structure of the fiddler crab, could help realize the all-weather vision and panoramic object detection.
