Unlocking a Greater Perspective: Mapping the Chemical Space of Biomes Using Sirius

Untargeted mass spectrometry is a powerful tool for analyzing the immense chemical complexity of natural environments. However, interpreting such large datasets remains a significant challenge. To overcome this, researchers have developed an innovative approach using SIRIUS that prioritizes chemical profiling over exhaustive identification. This method allows for more effective comparisons of (micro-)biomes, providing deeper insights into biochemical diversity across different environments.

SIRIUS on the body farm: Investigating microbial decomposers

Microbial decomposers break down human remains, recycling nutrients and influencing ecosystem dynamics. Is there a universal microbial decomposer network that assembles in response to mammalian remains? How does the network and the cadaver-derived nutrient pool change during the decomposition process and can this microbial community change be used for predicting time since death for forensic purposes?

Hydrate your skin with “biotics”: Understanding the impact of pre/postbiotics on skin health

Our skin, beyond being a physical barrier, hosts a diverse community of microorganisms known as the skin microbiota. “Biotics” have gained attention for their potential to enhance the skin’s health, though their exact mode of action is still unclear. MS-based metabolomics has emerged as a powerful tool to characterize the chemical composition of the skin surface and correlate it with microbial communities. Using CSI:FingerID, researchers identified changes in the skin metabolome that are more pronounced than changes in the microbial composition, suggesting that even subtle shifts in microbial abundance can lead to significant effects on the skin.
