New approach would eliminate visual disturbances without additional bulky optics. While most interaction with digital content is still constrained to keyboards and 2D touch panels, augmented and virtually reality (AR/VR) technologies promise ever more freedom from these limitations.

AR/VR devices can have their own drawbacks, such as a tendency to induce visual motion sickness or other visual disturbances with prolonged usage due to their stereoscopy or auto-stereoscopy based designs...

A tiny neuro controller developed by researchers at the University of Connecticut could provide more precise operation of micro biorobots, such as those being tested on ‘cyborg’ cockroaches for possible use in search and rescue missions inside collapsed buildings.

Scientists’ neuro-controller could improve performance of micro biobots. A tiny neuro-controller created by researchers at the University of Connecticut could provide more precise control of futuristic biobots, such as cyborg cockroaches that are already being tested for use in search and rescue missions inside collapsed buildings.

Scientists have spent the better part of the past decade exploring ways to tether live insects to miniaturized computer hardware so they can manipulate an ...

Yale University researchers have demonstrated one of the key steps in building the architecture for modular quantum computers: the “teleportation” of a quantum gate between two qubits, on demand.

The key principle behind this new work is quantum teleportation, a unique feature of quantum mechanics that has previously been used to transmit unknown quantum states between two parties without physically sending the state itself. Using a theoretical protocol developed in the 1990s, Yale researchers experimentally demonstrated a quantum operation, or “gate,” without relying on any direct interaction...

New research in the field of semi-artificial photosynthesis. They used natural sunlight to convert water into hydrogen and oxygen using a mixture of biological components and humanmade technologies. The research could now be used to revolutionise the systems used for renewable energy production.

A new paper, published in Nature Energy, outlines how academics at the Reisner Laboratory in Cambridge developed their platform to achieve unassisted solar-driven water-splitting. Their method also managed to absorb more solar light than natural photosynthesis...
