Quantum Holograms: Metasurfaces intertwin light and information with new research
Polarization and holographic information are intertwined with quantum holograms. Holographic characters indicate polarized intertwining of paired photons. By selecting different polarizer orientations for one photon, you can selectively erase specific characters in the hologram, and accurately control the intertwined holographic information. Credit: J. Diagram by Li (University of Exeter). Quantum entanglement is essentially a fundamental phenomenon and is one of…

Broiler growth rate contributes to behavioral differences and sheds light on the impact on welfare
Credit: Pixabay/CC0 Public Domain Poultry companies weigh costs and efficiency on higher animal welfare standards, a study comparing traditional, growing broiler varieties has shown that slow-growing chickens exhibit behaviors more closely related to positive welfare. Chickens, specially raised for meat production, are usually grown for 6-8 weeks, but must grow up for up to 12 weeks to mature. Though popular…

“Nanodot” controls may tweak light for sharper displays and quantum computing
Credit: ACS Photonics (2024). doi:10.1021/acsphotonics.4C01739 According to an international team led by researchers at Pennsylvania State University, it is possible that the newly achieved light is precisely controlled from very small sources, several nanometers embedded in two-dimensional (2D) materials, and several nanometers embedded in two-dimensional (2D) materials. In a recent study published in ACS Photonics, scientists worked together to show…

New research reveals the structure of violent winds 1,300 light years away
Credit: Pixabay/CC0 Public Domain Planet WASP-121B is extreme. It is a gas giant nearly twice the size of Jupiter, orbiting around very close to the stars, nearly 50 times more than the Earth does around the Sun. The WASP-121B is so close to that star that it locked its rotation with a “resonance.” Planets always show the same face to…

A hybrid state of light and material can significantly improve the brightness of the OLED
Research and Extended Map Overview. Credit: Advanced Optical Materials (2025). doi:10.1002/adom.202403046 Researchers have developed a theoretical model that predicts a significant increase in the brightness of organic light emitting diodes (OLEDs) by exploiting a new quantum state called polytons. Integrating Polaritons into OLEDS requires effective discovery of new materials, making practical implementation an exciting challenge. OLED technology has become a…
