Published Discovery and naming of Africa's oldest known dinosaur
(via sciencedaily.com) An international team of paleontologists has discovered and named a new, early dinosaur. The skeleton -- incredibly, mostly intact -- was found over the course of two digs, in 2017 and 2019.
Published Fossils of giant sea lizard that ruled the oceans 66 million years ago discovered
(via sciencedaily.com) Fossils of a giant killer mosasaur have been discovered, along with the fossilized remains of its prey.
Published All the better to better eat you with -- dinosaurs evolved different eye socket shapes to allow stronger bites
(via sciencedaily.com) Large dinosaur predators, such as Tyrannosaurus rex, evolved different shapes of eye sockets to better deal with high bite forces, new research has shown.
Published Prehistoric podiatry: How dinos carried their enormous weight
(via sciencedaily.com) Scientists have cracked an enduring mystery, discovering how sauropod dinosaurs -- like Brontosaurus and Diplodocus -- supported their gigantic bodies on land.
Published The speed at which spinosaurid dinosaur teeth were replaced accounts for their overabundance in Cretaceous sites
(via sciencedaily.com) Spinosaurid dinosaurs were able to develop up to three generations of teeth at the same time, a high replacement rate that explains why so many teeth of this type have been found in Cretaceous sites.
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.
Published Plesiosaur fossils found in the Sahara suggest they weren't just marine animals
(via sciencedaily.com) Fossils of small plesiosaurs, long-necked marine reptiles from the age of dinosaurs, have been found in a 100-million year old river system that is now Morocco's Sahara Desert. This discovery suggests some species of plesiosaur, traditionally thought to be sea creatures, may have lived in freshwater.
Published Study refutes claim that T. rex was three separate species
(via sciencedaily.com) A new study refutes a provocative claim made earlier this year that fossils classified as the dinosaur Tyrannosaurus rex represent three separate species. The rebuttal finds that the earlier proposal lacks sufficient evidence to split up the iconic species.
Published Robot dog learns to walk in one hour
(via sciencedaily.com) Like a newborn animal, a four-legged robot stumbles around during its first walking attempts. But while a foal or a giraffe needs much longer to master walking, the robot learns to move forward fluently in just one hour. A computer program acts as the artificial presentation of the animal's spinal cord, and learns to optimize the robot's movement in a short time. The artificial neural network is not yet ideally adjusted at the beginning, but rapidly self-adjusts.
Published Virtual reality app trial shown to reduce common phobias
(via sciencedaily.com) The trial studied phobia patients using a headset and a smartphone app treatment programme -- a combination of Virtual Reality (VR) 360-degree video exposure therapy and cognitive behavioural therapy (CBT).
Published A new giant dinosaur gives insight into why many prehistoric meat-eaters had such tiny arms
(via sciencedaily.com) An international team has discovered a new big, meat-eating dinosaur, dubbed Meraxes gigas, that provides clues about the evolution and anatomy of predatory dinosaurs such as the Carcharodontosaurus and Tyrannosaurus rex. Meraxes measured around 36 feet from snout to tail tip and weighed approximately 9,000 pounds.
Published Dinosaurs took over amid ice, not warmth, says a new study of ancient mass extinction
(via sciencedaily.com) There is new evidence that ancient high latitudes, to which early dinosaurs were largely relegated, regularly froze over, and that the creatures adapted -- an apparent key to their later dominance.
Published Virtual reality technology could strengthen effects of traditional rehabilitation for multiple sclerosis
(via sciencedaily.com) By increasing sensory input and promoting multisensory processing, virtual reality may increase the effectiveness of traditional cognitive rehabilitation and exercise training in individuals with MS, according to researchers.
Published 'Fake' data helps robots learn the ropes faster
(via sciencedaily.com) In a step toward robots that can learn on the fly like humans do, a new approach expands training data sets for robots that work with soft objects like ropes and fabrics, or in cluttered environments.
Published Supernumerary virtual robotic arms can feel like part of our body
(via sciencedaily.com) Researchers have developed a virtual robotic limb system which can be operated by users' feet in a virtual environment as extra, or supernumerary, limbs. After training, users reported feeling like the virtual robotic arms had become part of their own body. This study focused on the perceptual changes of the participants, understanding of which can contribute to designing real physical robotic supernumerary limb systems that people can use naturally and freely just like our own bodies.
Published Ultra-thin film creates vivid 3D images with large field of view
(via sciencedaily.com) Researchers have developed a new ultra-thin film that can create detailed 3D images viewable under normal illumination without any special reading devices. The images appear to float on top of the film and can be clearly viewed from all angles. The new imaging film uses a technology known as light-field imaging, which captures the direction and intensity of all rays of light within a scene to create a 3D image. With additional development, the new glass-free approach could be used as a visual security feature or incorporated into virtual or augmented reality devices.
Published Training virtually can reduce psychosocial stress and anxiety
(via sciencedaily.com) Everyone knows that exercise brings physical and psychological benefits. A new study suggests that virtual reality exercise induces similar effects, meaning those with limited mobility may be able to improve their mental well-being.
