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.

Palaeontologists have identified the remains of one of Europe's largest ever land-based hunters: a dinosaur that measured over 10m long and lived around 125 million years ago.

The fossil of a still-unnamed species provides the first known record of the abelisaurid group of theropods from a middle Cretaceous-aged (approximately 98 million years old) rock unit known as the Bahariya Formation, which is exposed in the Bahariya Oasis of the Western Desert of Egypt.

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.

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.

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 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.

Crafty hackers can make a tool to eavesdrop on some 6G wireless signals in as little as five minutes using office paper, an inkjet printer, a metallic foil transfer and a laminator.

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.

New research moves back the moment of the radiation of squamates -- the group of reptiles that includes lizards, snakes and worm lizards -- to the Jurassic, a long time before current estimates.

Precipitation more than temperature influenced the distribution of herbivorous dinosaurs in what is now Alaska, according to new research. The finding discusses the distribution of hadrosaurids and ceratopsids -- the megaherbivores of the Late Cretaceous Period, 100.5 million to 66 million years ago.

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.
