The finding is that older diesel engines and renewables produce measurable adverse effects in microglial stem cells, but new diesel formulations in new engines do not. The implication is that policy-makers should accelerate the transition to newer diesel and abandon reusable diesel. Since Europe has been gung-ho for diesel for decades, this finding could have significant regulatory and market effects.
