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).

According to a new study, the first louse to take up residence on a mammalian host likely started out as a parasite of birds. That host-jumping event tens of millions of years ago began the long association between mammals and lice, setting the stage for their coevolution and offering more opportunities for the lice to spread to other mammals.

The fossil record tells us about ancient life through the preserved remains of body parts like bones, teeth and turtle shells. But how to study the history of soft tissues and organs, which can decay quickly, leaving little evidence behind? In a new study, scientists use gene expression patterns, called transcriptomics, to investigate the ancient origins of one organ: the placenta, which is vital to pregnancy.

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.

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.

Australian palaeontologists have described a new genus of giant fossil kangaroo from the mountains of central Papua New Guinea. The new description of the fossil kangaroo has found that, rather than being closely related to Australian kangaroos, it most likely belongs to a unique genus of more primitive kangaroo found only in PNG.

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.

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.

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.

A new study finds that the more a person stares at themself while talking with a partner in an online chat, the more their mood degrades over the course of the conversation. Alcohol use appears to worsen the problem, the researchers found.

Using radio transmitters, scientists have gained new insights into the behavior of medium ground finches in the Galapagos Islands. A study reveals daily movement patterns covering an area equivalent to the size of 30 soccer fields.

Researchers have conducted a 10-week study to evaluate how text messaging a link to patients when their doctor is ready provides a way to connect patients and doctors without relying on the virtual waiting room.

New research suggests that determining evolutionary trees of organisms by comparing anatomy rather than gene sequences is misleading. The study shows that we often need to overturn centuries of scholarly work that classified living things according to how they look.

Paleontologists have debated whether dinosaurs were warm-blooded, like modern mammals and birds, or cold-blooded, like modern reptiles. In a new paper, scientists are unveiling a new method for studying dinosaurs' metabolic rates, using clues in their bones.

Scientists settle debate surrounding species that laid eggs exploited by early Australian people around 50,000 years ago. Shell proteins point to Genyornis, which was among the 'mega-fauna' to go extinct a few thousand years after humans arrived on the continent.

A computer-guided approach to design can propose more solutions and balance out human inexperience and design fixation.

Tactile sensation is an incredibly important part of how humans perceive their reality. Haptics or devices that can produce extremely specific vibrations that can mimic the sensation of touch are a way to bring that third sense to life. However, as far as haptics have come, humans are incredibly particular about whether or not something feels 'right,' and virtual textures don't always hit the mark. Now, researchers have developed a new method for computers to achieve that true texture -- with the help of human beings. Called a preference-driven model, the framework uses our ability to distinguish between the details of certain textures as a tool in order to give these virtual counterparts a tune-up.

Researchers shed light on the way Quetzalcoatlus would have flown, finding that the dinosaur's flying dynamics were actually very different to how it has been depicted in popular culture.

Researchers have published a roadmap for creating a digital twin of the immune system. Patterned after digital twins used in industry to test innovations on a model, the digital twin would create a virtual immune system tailored to individuals. Physicians could use this model to develop precision treatments based on a person's genetics and personal history. It could answer questions why some people react differently to COVID-19 infection, for example, or design precise immunosuppressant therapy for transplant patients, or allow pharmaceutical companies to more quickly bring drugs to market.

Researchers have developed a new method for designing large-scale metasurfaces that uses techniques of machine intelligence to generate designs automatically. The method will enable new metasurface designs that can make an impact on virtual or augmented reality, self-driving cars, and machine vision for embarked systems and satellites.
