Study places new constraints on the time variation of gravitational constant G
Past physics theories introduced several fundamental constants, including Newton's constant G, which quantifies the strength of the gravitational interaction between two massive objects. Combined,...
Spinning black holes could deform under an external and static gravitational field
An open question among the physics community is whether black holes can be tidally deformed by an external gravitational field. If this were confirmed to be true, it could have important...
Examining how humans develop trust towards embodied virtual agents
Embodied virtual agents (EVAs), graphically represented 3D virtual characters that display human-like behavior, could have valuable applications in a variety of settings. For instance, they could be...
A tactile sensing foot to increase the stability of legged robots
In order to effectively navigate real-world environments, legged robots should be able to move swiftly and freely while maintaining their balance. This is particularly true for humanoid robots,...
Study examines experience-dependent contextual codes in the hippocampus
The hippocampus is a brain structure within the temporal lobe known to play a key role in memory and learning. The hippocampus contains neural networks that support what is known as declarative...
Researchers develop a robotic guide dog to assist blind individuals
Guide dogs, dogs that are trained to help humans move through their environments, have played a critical role in society for many decades. These highly trained animals, in fact, have proved to be...
An AR interface to assist human agents during critical missions
In recent years, computer scientists and roboticists have developed a variety of technological tools to aid human agents during critical missions, such as military operations or search and rescue...
A two-qubit engine powered by entanglement and local measurements
Researchers at Institut Néel-CNRS, University of Saint Louis and University of Rochester recently realized a two-qubit engine fueled by entanglement and local measurements. This engine's unique...
The effects of solar flares on Earth’s magnetosphere
Planet Earth is surrounded by a system of magnetic fields known as the magnetosphere. This vast, comet-shaped system deflects charged particles coming from the sun, shielding our planet from harmful...
A new method to generate and control orbital angular momentum beams
Artificial spin ices (ASIs) are magnetic metamaterials with exotic properties that are dependent on their geometries. Over the past few years, many physicists have studied these materials, as their...
