Raise your hand if you ve ever had an avocado that was too hard and under ripe one day and become too squishy seemingly overnight. Or maybe you wanted a sandwich for lunch, but the lettuce that seemed fine at the supermarket was suddenly soggy and old.
Post-harvest researcher Tie Liu, an assistant professor with the University of Florida Institute of Food and Agricultural Sciences, knows the struggle. And he wants to help.
Liu is studying the possibility of creating a handheld or wearable device to test food freshness beyond what human senses are capable of finding. I ve seen this many times in my refrigerator. Sometimes you just bought a vegetable and then forget it, and just a few days later, it s all yellow, he said. Personally, I feel very wasteful. We need to have a better idea of how to manage it and reduce vegetable waste.

GAINESVILLE, Fla. (WCJB) -How many times have you thrown away produce that you either forgot about or ran out of time to eat? For most people, that number is countless.
Scientists with IFAS are using AI and x-ray technology to detect freshness signatures being emitted from your fruits and vegetables.
Eventually, their goal is to create an app or wearable device that can read how fresh produce is, and how long you have to use it.

An infrared view of NGC6334, the Cat’s Paw Nebula, a giant, star-forming molecular cloud. New submillimeter observations of the southern dark complex in this cloud have uncovered the first prestellar cores (embryos of future stars) ever found in a massive cloud, but they are very cold and cannot be seen in infrared images like this one.

Stars form as gravity contracts the gas and dust in an interstellar cloud until cores develop that are dense enough to coalesce into stars. A dense core in the earliest phase of this process is called a starless core, and if it has begun to collapse into a star the stage is referred to as a prestellar core. Prestellar cores can form single or multiple stars under the combined effects of gravity, magnetic fields, and turbulent motions, and understanding these and other properties of prestellar cores is critical to understanding star formation. Prestellar cores in low-mass molecular clouds have been inte
