Dear Readers,
Today we hear about the identification of fossil bones in a Belgian cave, Amazonian fungi that display bioactive compounds, and a new combined method to detect several poisons and toxins in food after a 2-year-old was intoxicated at home.
Also, the time for voting the BEST product innovation of 2023 has started!
Please cast your vote here.
Voting ends by October 14th 2022.
Enjoy the reading,

Mass spectrometry
A new proteomics approach using small sample sizes has been used to classify ten 130,000-year-old bones found in a Belgian cave. The mass spectrometric data on extracted collagens were used for species identification, matching with morphological data to reveal the presence of bears, big cats, and bovine species.

Bioactive compounds
Scientists from the Universidade Federal de Roraima, Universidade Estadual de Maringá, MS Bioscience, and Universidade Federal do Amazonas (all in Brazil) set out to explore the diverse range of compounds produced by endophytic fungi associated with Annona jahnii Saff, 1914 using UHPLC-MS/MS and molecular networking. The endophytic fungi are a rich source of bioactive compounds.

LC/MS/MS
Chinese scientists have developed a novel LC/MS/MS method to screen for 315 potentially harmful drugs in different foodstuffs and biological fluids using a mass spectral library that was constructed in-house. The method was used to confirm a real case of suspected poisoning when a two-year-old child consumed fish feed at home.
