  • Current electrochemical-based protein labelling methods suffer from limited site-selectivity and off-target reactivity owing to required radical/electrophilic reagents. Now an electrochemical strategy enables chemoselective labelling of proteins at a site-specifically incorporated 5-hydroxytryptophan residue using aromatic amines as coupling partners. This approach works on various proteins, including a full-length antibody, and is compatible with established click reactions.

  • Alkali metal cations influence electrocatalytic reactions, but their specific role remains elusive. Now, methyl4N+ is established as a vibrational probe for surface-enhanced infrared absorption spectroscopy, revealing that alkali metal cations specifically adsorb on Au during CO2 electroreduction and that their surface coverage depends on their free energy of hydration.

  • James Webb Space Telescope observations of Jupiter have unveiled the presence of a narrow and intense atmospheric jet in the equator of the planet near the tropopause. The jet’s speed of 500 km h−1 doubles the speed of the lower clouds. This new jet aligns with temperature and wind oscillations in Jupiter’s stratosphere.
