This star-forming region's Perseus Molecular Complex contained a high concentration of tryptophan.
The area is generally undetectable to the naked eye, but tryptophan molecules sparkle brilliantly when viewed through infrared wavelengths. The amino acid also has a distinct infrared light signature, making it an excellent target for our infrared-based telescope.
“The novelty of this work is that tryptophan has never before been detected in the interstellar medium, and furthermore, in spite of decades of research, there has been no confirmed detection of other amino acids in any other star formation region,” said Iglesias-Groth, in anAccording to the author, IC 348 is an "extraordinary chemical laboratory" that enables the most sensitive searches for various molecules in the interstellar medium.

Exciton annihilation in molecular aggregates suppressed through qu antum interference - Nature ChemistryExciton–exciton annihilation is conventionally assumed to be limited by diffusion. Now, using time-resolved photoluminescence microscopy to determine exciton diffusion constants and annihilation rates in two substituted perylene diimide aggregates, along with a microscopic model, it has been shown that annihilation can be suppressed through quantum interference of the spatial phase of delocalized excitons.
