Scientists discuss leaving the U.S. in this week's Expert Voices.

As the conditions for excellent research improve in many countries around the world, it is unavoidable that more and more U.S.-trained researchers will spend at least part of their careers abroad. This is not my big concern. Scientific research is not a zero-sum enterprise, where one country's gain is another's loss. Uncertain funding in the U.S. and impediments to open collaboration — like restrictions on immigration and visas or even social biases against foreigners — may increase incentives for researchers to go abroad; more importantly, those conditions, and anything else that makes scientific collaboration less easy, harms America.

The bottom line: It is not the flow of American scientists abroad that concerns me. It is the discouragement of the free flow of researchers in and out of our country — Americans and non-Americans.

Facebook boycott organizers share details on their Zuckerberg meeting

Facebook is in the midst of the largest ad boycott in its history, with nearly 1,000 brands having stopped paid advertising in July because they feel Facebook hasn't done enough to remove hate speech from its namesake app and Instagram.

Axios Re:Cap spoke with the boycott's four main organizers, who met on Tuesday with CEO Mark Zuckerberg and other top Facebook executives, to learn why they organized the boycott, what they took from the meeting, and what comes next.

Civil rights leaders blasted Facebook's top executives shortly after speaking with them on Tuesday, saying that the tech giant's leaders "failed to meet the moment" and were "more interested in having a dialogue than producing outcomes."

Why it matters: The likely fallout from the meeting is that the growing boycott of Facebook's advertising platform, which has reached nearly 1000 companies in less than a month, will extend longer than previously anticipated, deepening Facebook's public relations nightmare.

House Minority Whip Steve Scalise’s PAC is inviting lobbyists to attend a four-day “Summer Meeting” at Disney World's Polynesian Village in Florida, all but daring donors to swallow their concern about coronavirus and contribute $10,000 to his leadership PAC.

Why it matters: Scalise appears to be the first House lawmakers to host an in-person destination fundraiser since the severity of pandemic became clear. The invite for the “Summer Meeting” for the Scalise Leadership Fund, obtained by Axios, makes no mention of COVID-19.
