Apple's rumored no-prick glucose monitoring tech

Now available on your smart speaker and wherever you get your podcasts

It's Thursday, February 23, 2023.

Bloomberg sources claim Apple’s quest for no-prick blood glucose monitoring is now at a "proof-of-concept stage" and good enough that it could come to market once it's smaller. The technology, which uses lasers to gauge glucose concentration under the skin, was previously tabletop-sized but has reportedly advanced nearer to an iPhone-sized prototype.

It’s been in the works for a long time. In 2010, when Steve Jobs headed up Apple, the company bought blood glucose monitoring startup RareLight. But no-prick monitors are a challenge. In 2018, Alphabet's health subsidiary, Verily, scrapped plans for a smart contact lens that tried to track glucose using tears.

Notion's AI editor is now available to anyone who wants writing help

The company only began testing Notion AI late last year.

Last November, Notion, the popular note-taking app, began testing a built-in generative machine learning algorithm dubbed Notion AI. Now it’s ready for launch. Notion said anyone, including free users, can start using its AI-powered writing assistant. More than two million people signed up for the waitlist for the alpha version and, according to the company, most testers weren’t asking it to write blog posts and marketing emails from scratch. Instead, they were using it to refine their own writing. As a result, the company decided to “completely redesign” Notion AI to make it more “iterative and conversational.” The new version of the tool will generate follow-up prompts until you’re satisfied with its results.

Twitter’s 2FA paywall is a good opportunity to upgrade your security practices

The platform could become less secure – but that doesn't mean you have to be.

Twitter announced plans to pull a popular method of two-factor authentication for non-paying customers last week. Starting March 20th, if you don’t want to pay $8 to $11 per month for a Twitter Blue subscription (hi, that’s me!), you’ll no longer be able to use text message authentication to get into your account. There are still some options to keep your account secure. Software-based authentication apps like Duo, Authy, Google Authenticator and the 2FA authenticator built into iPhones either send you a notification or, in the case of Twitter, generate a token to complete your login, or you can use hardware-based security keys that plug into devices. We walk you through the options if you want to stick around on Twitter.
