New holographic storage method uses light to pack more data in less space

Light has always carried more than brightness. In this case, it also carries direction and twist. That mix may open a new ...

Beyond the Focus of Expansion: Retinal curl as a functional signal for heading estimation

This study provides an important and biologically plausible account of how human perceptual judgments of heading direction are influenced by a specific pattern of motion in optic flow fields known as ...

Quantum simulations tackle photon polarization flip, but today's hardware falls short

For the last 80 years, the theory of quantum electrodynamics (QED), which describes all electromagnetic interactions, has ...

REM sleep prefrontal high-frequency oscillation chains mediate distinct cortical – hippocampal reactivation patterns compared to NREM sleep

REM (rapid eye movement) and non-REM (NREM) sleep stages contribute to systems memory consolidation in hippocampal-cortical circuits. However, the physiological mechanisms underlying REM memory ...
