Microtoroid resonators are one of the most sensitive biochemical sensors, capable of detecting single molecules. Light is most commonly coupled into these sensors using a fragile and vibration-sensitive tapered optical fiber, preventing translation to field-portable sensing. Scientists from the University of Arizona have achieved far-field coupling of light to ultra-high quality factor microtoroids using a single objective lens. This is the foundation of a fully on-chip multiplexed microtoroid sensing platform.

Engineers at the University of California San Diego have discovered that some brain cells age more rapidly than others, and they are disproportionately abundant in individuals afflicted with Alzheimer’s disease. Additionally, researchers observed sex-specific differences in the aging process of certain brain cells, with the female cortex exhibiting a higher ratio of “old” oligodendrocytes to “old” neurons compared to the male cortex.

University at Albany researchers have been awarded $611,000 from the USDA National Institute of Food and Agriculture to develop a new, fast-acting tool for Salmonella detection. Similar to the test strips used to measure pH or detect COVID-19, it will display results on a color-changing panel — purple if positive, red if negative. If successful, the test will reduce the time it takes to detect salmonella in food from days to hours, making it possible to quickly implement preemptive measures to prevent human illness and lost revenue.
