For state-licensed marijuana retailers like Sam Brill, moving pot from Schedule 1 to Schedule 3 could let them claim basic business tax deductions.

Brill, the CEO of Ascend Wellness, says the change would free up millions of dollars for his company.

The Trump administration says rescheduling will also boost research.

But Jillian Schauer of the Cannabis Regulators Association says some key details are in limbo.

For example, she says, scientists need more sources for acquiring marijuana they can research.

Aviation regulators say there's been a rapid decline in staffing shortages at air traffic control facilities over the past week.

That's given the Department of Transportation and the Federal Aviation Administration the confidence that more air traffic controllers are coming to work.

Regulators lowered air traffic reductions at dozens of major airports from 6% of flights to 3% through the weekend, but they did not lift them entirely.

The FAA said the restrictions were necessary to keep the airspace safe as the agency grappled with widespread staffing shortages of air traffic controllers during the government shutdown.

But with the government reopened, air traffic controllers have finally received some of the back pay they earned,

and most are now back on the job.

The year Natalie Grabeau turned 60, she started learning to swim.

But that was 20 years ago.

On Saturday, Grabeau finished the grueling Ironman course in Hawaii.

At 80 years old, she swam more than two miles in the ocean, biked 112 miles, and then ran a marathon-length course.

She set a new record as the oldest female athlete to finish the race.

That brought wide praise for Grabeau, who trains at her local YMCA and a high school track near her home in New Jersey.

In an email to NPR before her flight home, Grabeau says she's grateful she can still compete.
