Commonwealth Fusion Systems, a Cambridge, Mass.-based startup focused on commercializing fusion energy, raised $115 million in Series A funding.

Why it matters: Nuclear fusion, the process of combining hydrogen atoms rather than splitting them, has long been the clean energy industry's holy grail, promising unlimited output without creating any carbon emissions or nuclear waste.

  • CFS, spun out of MIT, claims it could have demonstrations by 2021 and a full facility prototype by 2025.
  • Investors: Future Ventures, Khosla Ventures, Lowercase Capital, Moore Strategic Ventures, Safar Partners, Schooner Capital, Starlight Ventures, Breakthrough Energy Ventures, Eni and The Engine.

The bottom line: Stay skeptical, as there are scientific and cost reasons why no one has successfully commercialized nuclear fusion, but this is a well-funded moonshot that's worth watching.

Newly released transcripts of bodycam footage from the Minneapolis Police Department show that George Floyd told officers he could not breathe more than 20 times in the moments leading up to his death.

Fighting the coronavirus infodemic

An "infodemic" of misinformation and disinformation has helped cripple the response to the novel coronavirus.

Why it matters: High-powered social media accelerates the spread of lies and political polarization that motivates people to believe them. Unless the public health sphere can effectively counter misinformation, not even an effective vaccine may be enough to end the pandemic.
