Best of the Week: Olive Oil, Young Scientist Award, The Future of Forensic Analysis
Top articles published this week include highlights from the recently released “The Future of Forensic Analysis,” articles about detecting olive oil fraud, and an announcement from 3M regarding the winner of their Young Scientist competition.
New Study Reveals How NASA’s Perseverance Rover Uses LIBS for Precise Mars Rock Analysis
NASA’s Perseverance rover is collecting valuable information for scientists back on Earth. A recent study explored how laser-induced breakdown spectroscopy (LIBS) is being used to analyze the Martian surface.
New Spectroscopy Method Shows Promise for Detecting Olive Oil Fraud
November 12th 2024Researchers from the University of Cordoba have validated a novel spectroscopy technique to help distinguish between extra virgin and virgin olive oils. This approach could support existing panel-based tests, which are often slow, costly, and subjective, by providing a faster, non-destructive screening option.
A recent study presents a new technique that combines femtosecond double-pulse laser-induced breakdown spectroscopy (fs-DP-LIBS) with machine learning (ML) algorithms to significantly enhance tissue discrimination and signal quality, paving the way for more precise biomedical diagnostics.
Young Scientist Awardee Uses Spectrophotometry and AI for Pesticide Detection Tool
Sirish Subash is the winner of the Young Scientist Award, presented by 3M and Discovery education. His work incorporates spectrophotometry, a nondestructive method that measures the light of various wavelengths that is reflected off fruits and vegetables.
