Tiny 'ruler' can gauge distances as small as an atom.

A recent article in New Scientist discusses a groundbreaking development in the field of chemistry - the creation of a tiny "ruler" that can measure distances as small as an atom within a protein. This innovation has the potential to aid in understanding how proteins fold and function, which is crucial for conditions like Alzheimer's disease. While the new method shows impressive precision, there are limitations to its application in more complex biological systems, as noted by Kirti Prakash at The Royal Marsden NHS Foundation Trust and Institute of Cancer Research in the UK.
