A recent study finds that realism is a key factor in determining whether viewers engage with virtual reality videos -- and that engagement is itself a key factor in determining whether viewers are interested in watching VR videos in the future.

By clarifying the role of 'real' and 'virtual' charge carriers in laser-induced currents, researchers have taken a decisive step toward creating ultrafast computers.

Fruit flies synchronize the movements of their heads and bodies to stabilize their vision and fly effectively, according to researchers who utilized virtual-reality flight simulators. The finding appears to hold true in primates and other animals, the researchers say, indicating that animals evolved to move their eyes and bodies independently to conserve energy and improve performance. This understanding could inform the design of advanced mobile robots.

When you live in the driest State in the driest country in the world, bushfires are an unfortunate, and all-too-regular part of life. Learning how to survive such emergencies is important for all people, but especially for our youngest citizens.

Scientists combine materials science invention with newly developed 3D printing technology. Components made of highly transparent glass can be manufactured in just a few minutes and with great geometric freedom. Possible applications of the new process technology are micro-optical components of sensors, microscopes or lab-on-a-chip systems

Researchers have developed new polymer materials that are ideal for making the optical links necessary to connect chip-based photonic components with board-level circuits or optical fibers. These materials can be used to easily create interconnects between photonic chips and optical printed circuit boards, the light-based equivalent of electronic printed circuit boards.

Researchers have used virtual reality and 3D eye-tracking technology to examine what drew the attention of the visitors when entering the stunning environment of an ancient Roman house. The team recreated the House of Greek Epigrams in 3D and tracked the gaze of study participants as they viewed the home.

Researchers have demonstrated a more effective way to support learning and increase engagement at science-focused museum exhibits. They used artificial intelligence to create a new genre of interactive, hands-on exhibits that includes an intelligent, virtual assistant to interact with visitors. When the researchers compared their intelligent exhibit to a traditional one, they found that the intelligent exhibit increased learning and the time spent at the exhibit.

Skin cells and their DNA varies between individuals, but new data shows that some groups of people have higher variability in their cell deposits. The South Australian forensic science researchers are building a suite of new insights into crime scene investigation -- including the difference between high, intermediate and low skin 'shedders' that will help understanding of trace or 'touch DNA'.

Working out isn't known for being fun. But new active video and virtual reality games may help change that. Exergaming, or active video gaming, may be the perfect introduction to helping people be more active, according to new research.

Researchers have developed a metasurface attachment that can turn just about any camera or imaging system, even off-the-shelf systems, into polarization cameras. The attachment uses a metasurface of subwavelength nanopillars to direct light based on its polarization and compiles an image that captures polarization at every pixel.

A challenge to adopting augmented reality (AR) in wider applications is working with dynamic objects, owing to a delay between their movement and the projection of light onto their new position. But, scientists may have a workaround. They have developed a method that uses multiple projectors while reducing delay time. Their method could open the door to a future driven by AR, helping us live increasingly technology-centered lives.

Scientists who interact with others during assigned sessions at conferences are more likely to form productive collaborations than scientists who do not, researchers found. And the kicker? It doesn't matter whether the conference is in person or virtual.

Researchers aim to streamline the time- and resource-intensive process of screening ligands during catalyst design by using virtual ligands.

Experts have developed a unique method for retrieving high resolution images of fingermarks from curved objects like bullet casings that offers greater detail and accuracy than traditional forensic methods.

To counter hacking, researchers have developed a new system based on the concept of 'zero-knowledge proofs', the security of which is based on the physical principle of relativity: information cannot travel faster than the speed of light. Thus, one of the fundamental principles of modern physics allows for secure data transfer.

Researchers report that the way a tissue's cells are arranged can serve as a fingerprint for the tissue's 'phase' -- whether it is more like a solid, liquid, or gas. For example, tumors that are more solid may be relatively stable, whereas more fluid-like growths could be more prone to mutate and metastasize.

Uses of facial images and facial recognition technologies -- to unlock a phone or in airport security -- are becoming increasingly common in everyday life. But how do people feel about using such data in healthcare and biomedical research?
