A new study analyzing diet, average plasma sugar levels and cancer prevalence in some 273 vertebrate species showed surprising results. The study found no significant link between diet and plasma sugar levels across nonhuman vertebrate species, suggesting that glucose regulation is likely influenced more by evolutionary and physiological adaptations than diet alone. Birds in particular did not suffer increased cancer rates compared with mammals and reptiles, despite having higher blood glucose levels, which are associated with increased cancer risk in other animals, including humans.

Researchers from Hong Kong and the UK have developed a novel method for creating quantum holograms using metasurfaces, as detailed in a recent study published in Advanced Photonics. By combining metasurfaces with nonlinear crystals, they achieved entanglement of polarization and holographic information. This innovative approach allows for the generation of quantum holograms, where specific holographic letters can be selectively erased by adjusting the polarization of entangled photons. The study demonstrates the potential of metasurfaces to enhance quantum communication and anti-counterfeiting technologies, offering a compact and flexible alternative to conventional materials. This breakthrough not only advances our understanding of quantum mechanics but also paves the way for practical applications in quantum information processing.
