You may not realize it, but when you send a spit-filled tube off to a lab that’s going to analyze your DNA, you’re linking the most unique identifier possible (your gene sequence) to other sensitive personal information, like your name, home address, and credit card number. How can you know that the DNA lab will properly decouple your genetic data from your personal information? Well, you just have to trust them.

Obviously, that arrangement isn’t ideal, which is why a new startup called Nebula is using robust digital privacy protocols—encrypted email, VPNs, and blockchain technology—to guard its customers’ information. WIRED reporter Megan Molteni joins us this week to talk about genetic sequencing, how personal data is handled, and what this startup is doing to change the best practices within the industry.

Also, there’s a new Facebook Portal in the world, Amazon is cracking down on shady shopping apps, and we’ll tell you why you should wait to upgrade to iOS 13.

Show Notes: Read Megan’s story about Nebula’s use of blockchain technology here. Tom Simonite tells us about the new Facebook Portal. Lauren Goode on iOS 13’s many bugs. Louise Matsakis on Amazon’s app crackdown.
