Ultrafast charge dynamics in the amino acid phenylalanine excited by an attosecond pulse: the snapshots reveal a notable variation of the charge density with a period of a few femtoseconds. The measurement of this ultrafast electron dynamics is a crucial benchmark for the extension of attosecond techniques to complex molecules.
