Joe Biden is visiting Kenosha, Wisconsin today, the city where Jacob Blake was shot by police last week. And where two people died after the black lives matter protests turned violent. His visit comes a few days after Trump’s own visit on Monday.
Axios talked to 10 swing voters in Wisconsin about their feelings on the protests in their state and the upcoming election.
Plus, the latest on Covid-19 cases in the U.S.
And, a new type of black hole in deep space.
Guests: Axios’ Alexi McCammond, Sam Baker, and Miriam Kramer.
Particulate pollution is a serious threat to human health, but the way that new particles form is poorly understood. This week, new research suggests a new mechanism for it to happen. Research article: Wang et al.; News and Views: Airborne particles might grow fast in cities
Measles is a dangerous infection that can kill. As many as 100,000 people die from the disease each year. For those who survive infection, the virus leaves a lasting mark—it appears to wipe out the immune system’s memory. News Intern Eva Fredrick joins host Sarah Crespi to talk about a pair of studies that looked at how this happens in children’s immune systems.
In our second segment this week, Sarah talks with Todd Thompson, of Ohio State University in Columbus, about his effort to find a small black hole in a binary pair with a red giant star. Usually black holes are detected because they are accruing matter and as the matter interacts with the black hole, x-rays are released. Without this flashy signal, black hole detection gets much harder. Astronomers must look for the gravitational influence of the black holes on nearby stars—which is easier to spot when the black hole is massive. Thompson talks with Sarah about a new approach to finding small, noninteracting black holes.
