Portable spectrophotometer approach predicts strawberry shelf life in real time
Graphical summary. Credit: Postharvest Biology and Technology (2024). DOI: 10.1016/j.postharvbio.2024.113189 A research group at the University of Cordoba has created a tool based on non-invasive techniques to ensure optimal strawberry quality and minimize food waste. According to the United Nations, 930 million tons of food was wasted globally in 2019. Reducing food waste is essential, as these losses occur at…

Physics
Findings from the experimental setup indicate the feasibility of a small, portable nuclear clock.
(Left) VUV signal versus exposure time immediately after X-ray beam irradiation of a 229Th-doped CaF2 crystal. The VUV signal as a function of exposure time reaches a saturation value about 10 times faster than the expected decay half-life. (Right) Observed time profile of an isomeric decay signal with a half-life of about 450 seconds. This suggests that the isomeric state…
