Tech Xplore / New augmented reality tech can turn any surface into keyboard

Virtual keyboards are a frequent source of frustration for augmented reality (AR) users. The virtual surfaces are slow and error prone, and raising an arm to type on them can cause muscle strain known as "gorilla arm."

Medical Xpress / Microglia modulate the reactivity of astrocytes in Alzheimer's disease, study finds

Alzheimer's disease (AD) is a highly debilitating neurodegenerative disease characterized by the progressive loss of memory and decline of mental functions. Earlier research has uncovered some of the neural and biological ...

Phys.org / Key driver of extreme winds on Venus identified

Imagine the catastrophic winds of a category 5 hurricane. Now, imagine even faster winds of more than 100 meters per second, encircling the planet and whipping clouds across the sky, with no end in sight. This scenario would ...

Phys.org / Physicists demonstrate the constancy of the speed of light with unprecedented accuracy

In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley failed to measure the speed of Earth by comparing the speed of light in the direction of Earth's ...

Phys.org / When superfluids collide, physicists find a mix of old and new behavior

Physics is often about recognizing patterns, sometimes repeated across vastly different scales. For instance, moons orbit planets in the same way planets orbit stars, which in turn orbit the center of a galaxy.
