Researchers have developed a thin-film lithium niobate integrated photonic receiver for dual-band radar, integrating electro-optic modulation and microwave demultiplexing on a single chip. Published in PhotoniX Synergy, the work combines integrated dual-band signal processing with coherent fusion to enable a 12-GHz equivalent bandwidth and a 1.27-cm ranging resolution, providing a highly integrated pathway toward microwave photonic radar systems.

What if checking medication levels were as simple as enjoying a lollipop? A candy-coated device, called Lollylab, could provide the answer. In ACS Sensors, researchers describe how the lollipop’s stem transfers saliva to a sensor that measures acetaminophen levels. In an initial test, a peach-flavored prototype reliably detected the pain reliever in six people’s saliva in less than two minutes. Participants also found it more comfortable and easier to use than traditional collection swabs.
