5 Key Takeaways

• 1

  MALDI mass spectrometry imaging combined with machine learning allows detailed analysis of artworks, revealing pigments and binders without damaging them.

• 2

  A new workflow successfully mapped the cochlea's molecular landscape at 5-micrometer resolution, identifying distinct lipid and metabolite signatures.

• 3

  Submicrometer mass spectrometry imaging tracks lipid changes during apoptosis in single cells, revealing variability in responses to different anticancer drugs.

• 4

  Nanoplastics are found throughout the North Atlantic, with concentrations suggesting they may rival or exceed previous estimates for marine plastic pollution.

• 5

  Lehigh University's HEAL Service Center provides high-resolution mass spectrometry access for research in exposomics, metabolomics, and proteomics.
