Tryptophan is among the 20 vital amino acids necessary for protein synthesis, crucial for life's evolution on Earth. This amino acid has many spectral features in the infrared, as had been previously characterized by Susana Iglesias Groth, an IAC researcher. Utilizing data from the Spitzer Space

“IC 348 is an exceptional star formation region and an extraordinary chemical laboratory; thanks to its proximity to Earthy we can carry out some of the most sensitive searches for molecules in the interstellar medium” notes Iglesias-Groth, who “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” emphasizes the researcher.

Efficient fuel-molecule sieving using grapheneA research team has successfully developed a new method that can prevent the crossover of large fuel molecules and suppress the degradation of electrodes in advanced fuel cell technology using methanol or formic acid. The successful sieving of the fuel molecules is achieved via selective proton transfers due to steric hindrance on holey graphene sheets that have chemical functionalization and act as proton-exchange membranes.
