Researchers have developed a tiny, room-temperature device that creates a special type of structured light called radially polarized photons, which are highly useful for secure communication, advanced imaging, and precision optical tools. By carefully designing and positioning a quantum dot within a nanoantenna, they achieved high-quality light with over 93% polarization purity. This breakthrough helps improve the efficiency and practicality of devices that use structured light, paving the way for advancements in communication and optical technology.

 “Tasting Upside-Down - An Unusual Sensing Mechanism was Found in Human Bitter Sensing” A new study revealed that some bitter molecules target their sensor through binding simultaneously at two distinct locations, one outside the cell, and the other inside it. This discovery is fascinating because bitter taste receptors are expressed in extra-oral tissues and the new study shows the potential of our cells to sense not only external but also internal signals, opening up new possibilities for drug design, including asthma and inflammation.
