Health regulators around the world — including the FDA — are investigating whether metformin, a popular drug used to treat Type 2 diabetes, contains unsafe amounts of NDMA, a carcinogen, Bloomberg reports.

What they're saying: "The agency is in the beginning stages of testing metformin," an FDA spokesman told Bloomberg in a statement. "However, the agency has not confirmed if NDMA in metformin is above the acceptable daily intake (ADI) limit of 96 nanograms in the U.S."

  • The European Medicines Agency has also urged companies to test for high levels of NDMA in metformin.

Context: Concerns about NDMA have been increasing since it was found in blood pressure drugs and those containing ranitidine.

Yes, but: This news isn't necessarily bad, former FDA commissioner Scott Gottlieb told Axios.

  • "There's likely to be more reports of regulatory efforts to look for these risks, and perhaps additional findings," he said. "Because we're now more focused on mitigating these theoretical risks. That's not necessarily a bad thing. Our expectation of safety and our ability to control for it has increased."

Kamala Harris and the political rise of America's Indian community

When Democrats next week formally nominate the daughter of an Indian immigrant to be vice president, it'll be perhaps the biggest leap yet in the Indian American community's rapid ascent into a powerful political force.

Why it matters: Indian Americans are one of the fastest-growing, wealthiest and most educated demographic groups in the U.S. Politicians work harder every year to woo them. And in Kamala Harris, they'll be represented in a major-party presidential campaign for the first time.

The cardiac threat coronavirus poses to athletes

Cardiologists are increasingly concerned that coronavirus infections could cause heart complications that lead to sudden cardiac death in athletes.

Why it matters: Even if just a tiny percentage of COVID-19 cases lead to major cardiac conditions, the sheer scope of the pandemic raises the risk for those who regularly conduct the toughest physical activity — including amateurs who might be less aware of the danger.
