Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, told CNN Tuesday that the White House coronavirus task force will hold an "active discussion" about broadening the use of medical masks to protect against coronavirus.

Why it matters: Such a guidance shift would be a huge change in messaging from the Trump administration, which initially advised against healthy people using masks.

  • Currently, only sick people and health care workers are advised to wear masks due to shortages of personal protective equipment.
  • Fauci also said that part of the administration's hesitation regarding broadening the guidance was ensuring that enough of a supply remains for at-risk populations, like health care workers.

What he's saying:

"When we get in a situation where we have enough masks, I believe there will be some very serious consideration about more broadening this recommendation of using masks. We're not there yet, but I think we're close to coming to some determination. Because if, in fact, a person who may or may not be infected wants to prevent infecting someone else, one of the best ways to do that is with a mask, so perhaps that's the way to go. And again, I say, Jim, that's under very active consideration. We'll be discussing it today, this afternoon, at the task force meeting."

The big picture: Scientists and researchers have suggested that the administration could post guidelines about creating do-it-yourself masks — such as a bandana or cloth over one's face — for asymptomatic people.

  • A report from the Washington Post out Tuesday cited internal CDC talks on possibly recommending the public use DIY cloth masks as protective gear.
  • Former FDA Commissioner Scott Gottlieb told CBS' "Face the Nation" on Sunday that "we should be putting out guidelines from the CDC on how you can develop a mask on your own.”

Post-debate poll finds Biden strong on every major issue

This is one of the bigger signs of trouble for President Trump that we've seen in a poll: Of the final debate's seven topics, Joe Biden won or tied on all seven when viewers in a massive Axios-SurveyMonkey sample were asked who they trusted more to handle the issue.

Why it matters: In a time of unprecedented colliding crises for the nation, the polling considered Biden to be vastly more competent.

The murder hornets are here

Entomologists in Washington state on Thursday discovered the first Asian giant hornet nest in the U.S.

Why it matters: You may know this insect species by its nom de guerre: "the murder hornet." While the threat they pose to humans has been overstated, the invading hornets could decimate local honeybee populations if they establish themselves.
