The FDA announced today that U.S. marshals raided StemImmune, a San Diego-based clinic offering a smallpox vaccine to cancer patients, on Friday as part of an crackdown on stem-cell clinics offering unapproved and unproven treatments.

The vaccine won't generate smallpox for people with healthy immune systems, but could cause severe medical problems for cancer patients.

Clinics like StemImmune have been on the rise in the past several years, per The Washington Post. The clinics capitalize on the uncertainty of the developing field, offering unproven and potentially dangerous treatments. FDA Commissioner Scott Gottlieb noted the potential of regenerative medicine, but said "a small number of unscrupulous actors" put the field at risk.

What's next: The FDA says it will use "whatever legally enforceable means are necessary to protect the public health." New framework to establish clear guidelines and regulations will be advanced this fall.

Twitter will start pinning notices to the top of all U.S. Twitter users’ timelines warning that results in next week’s election may be delayed and that they may encounter misinformation on mail-in voting.

Why it matters: Delayed election results are expected across many states that are handling unprecedented amounts of absentee and mailed ballots, which President Trump has baselessly called "very dangerous" and "corrupt."

Water on the Moon might be more easily accessible than previously thought, opening up new possible avenues for future human exploration, according to a new study.

Why it matters: NASA is aiming to send people back to the Moon as part of its Artemis program by 2024, with plans to eventually create a sustainable presence on the lunar surface. That sustainability relies on mining the moon for its resources, like water.

Vice President Mike Pence no longer plans to attend the Senate's final confirmation vote for Judge Amy Coney Barrett, a Pence aide confirmed to CNN and Politico on Monday. On Sunday, Senate Democrats claimed that his presence after possible exposure to the coronavirus would be a "violation of common decency."

Driving the news: Five of Pence's aides were recently diagnosed with COVID-19, including his chief of staff, who is currently quarantining. Pence has continued his campaign travel despite his possible exposure, which goes against CDC guidelines.
