Eurekalert:
How many microbes inhabit our body on a regular basis? For the last few decades, the most commonly accepted estimate in the scientific world puts that number at around ten times as many bacterial as human cells. In research published today in the journal Cell, a recalculation of that number by Weizmann Institute of Science researchers reveals that the average adult has just under 40 trillion bacterial cells and about 30 trillion human ones, making the ratio much closer to 1:1.
This new calculation was done for a book called
Cell Biology by the Numbers,
which looks really interesting and right up a physics student's alley. Unfortunately, just the paperback version is $49.95 at Amazon.
