The researchers basically amplified and then short - circuited E. coli's internal machinery for producing large fatty - acid molecules, enabling them to
convert precursor molecules directly into fuels and other chemicals.
Previous studies have revealed that exercise induces the production of irisin and its
precursor molecule, FNDC5 (fibronectin - type III domain - containing 5) protein, which
convert white fat tissue into beneficial, calorie - burning brown fat.
