In BioNumbers we aim to enable you to find in one minute any useful molecular biology number that can be important for your research. BioNumbers currently attracts >3000 visitors a month from over 50 countries.
To cite BioNumbers please refer to: Milo et al. Nucl. Acids Res. (2010) 38 (suppl 1): D750-D753. When using a specific entry from the database it is recommended that you also specify the BioNumbers 6 digit ID, e.g. "BNID 100986, Milo et al 2010".
The BioNumbers database started in 2007 by Ron Milo, Paul Jorgensen and Mike Springer while sharing a bay at the Systems Biology department in Harvard. It was inspired by a table comparing values of key properties in bacteria, yeast and a mammalian cell line in Uri Alon’s book – "Introduction to systems biology"
and by the CyberCell project.
BioNumbers is coordinated and developed at the Milo lab in the Weizmann Institute of Science in Israel. Uri Moran is the hero that enters the vast majority of entries and curates the database. Feel free to write us a note at
The database interface was designed by Alon Gildoni and implemented & developed by Uri Simchoni, CEO of Prometheus. The BioNumbers logo was designed by Ricardo Vidal. It is our hope that the database will facilitate quantitative analysis and reasoning in a field of research where numbers tend to be “soft” and difficult to vouch for.
Financial support for the effort is being given by the Systems biology department in Harvard and by the Weizmann Institute of Science. Prof. Rob Phillips of Caltech is a constant source of advice and inspiration for advancing the bioNumbers cause and is the coauthor of the complementary book Cell Biology by the Numbers (free online).
