SI units
One year ago, on World Metrology Day (2019-May-20) the redefinition of the SI units came into force. Science faced one of the largest overhauls in history of scientific units. How to commemorate this event of groundbreaking innovation better than with the online publication of Mitochondrial physiology and with the launch of an innovative journal — Bioenergetics Communications.
Bioblast alert 2020(09) - MitoEAGLE News: 2020-04-09
