Hey Smarties! We’re off for the Fourth of July holiday. So today we’re bringing you a super fun episode of “Million Bazillion” that’ll teach you and your kiddos about a bit of our nation’s history and a highly secretive landmark. It’s all about Fort Knox, known as one of the most secure places in the world, and why it holds so much of the country’s gold. Plus, its role in stabilizing the U.S. economy in a time of crisis.

Much in our modern lives depends on GPS. But the United States’ GPS system is getting old and hasn’t kept up with international competition. We’ll get into how this leaves the U.S. vulnerable to national security threats. And, new data shows that as abortion protections have eroded across the country, more young women have been getting sterilized. Plus, one nonprofit’s work to give kids who’ve aged out of foster care a bona fide college move-in experience, and a women’s soccer stadium’s surprise success story.

Here’s everything we talked about today:

• “Why GPS Is Under Attack” from The New York Times
• “Rate of Young Women Getting Sterilized Doubled After Roe Was Overturned” from MedPage Today
• “Move-In Day Mafia Helps Kids From Foster Care Settle In College” from Black Enterprise
• “No One Wanted to Finance Their Stadium. Now Every Game Is a Sellout.” from The Wall Street Journal

It’s been about four years since the great remote work experiment took off for many employees who work computer-bound jobs. After plenty of back and forth between return-to-office mandates and work-from-home advocates, neither side really won. Data from the Bureau of Labor Statistics shows that the share of Americans doing some or all of their work from home has leveled off to about 35%. On the show today, The New York Times’ Emma Goldberg explains who’s working from home these days and how it’s impacting both employees and their bosses. Plus, the commercial real estate question looms large over the remote work debate.

Then, we’ll get into why the Joe Biden administration’s new protections for workers in extreme heat could be threatened by recent Supreme Court rulings and a potential second Trump presidency. And, the CEO of GS1, the company administering retail barcodes, didn’t see the QR code takeover coming.

Here’s everything we talked about today:

• “Work From Home Data Shows Who’s Fully Remote, Hybrid and in Person” from The New York Times
• “Research: How Remote Work Impacts Women at Different Stages of Their Careers” from Harvard Business Review
