Twitter selects researchers to investigate its "conversational health," leaked photos may show new iPhones and John Oliver takes on Facebook. Here's your Daily Crunch for July 30, 2018.

1. Twitter turns to academics to improve conversational health on the platform

In March, Twitter called for proposals from researchers around how they might measure and improve conversational health on the platform. Now the company has chosen two research teams to focus on two different issues — echo chambers and intergroup conflict.

It sounds like this is all pretty far removed from leading to concrete changes on Twitter itself, but at least the company is working with outside researchers to try to understand the issues at stake.

2. This is what the next iPhone could look like

Most likely, the devices in the leaked photos aren't actual iPhones. Instead, they're dummy units created by manufacturers based on leaked design schematics — but these units usually look just like the real thing.

3. John Oliver makes an honest Facebook ad

"Seriously you guys, we were making so much money off of you, you don't even understand."

4. Grover raises €37M Series A to offer latest tech products as a subscription

The startup has also been trialling a B2B product called Startups get Grover. Apparently there was demand from startups that want, for example, to subscribe for access to MacBooks for their new employees.

5. Tesla is making a $1500 … surfboard?

Tesla says, "The Limited Edition Tesla Surfboard features a mix of the same high-quality matte and gloss finishes used on all our cars." I mean, sure? But it looks like they're already sold out.

6. This is the leaked DJI Mavic 2 drone

Just like the original, it's a small, foldable drone. This time around, there will be two different versions, the Zoom and the Pro, though both will reportedly have the ability to fly at 45mph with a range of five miles.

7. A podcast is a song in your heart

Last week's episode of Equity looked at Facebook's falling stock price, while your hosts at TechCrunch Mixtape (previously known as CTRL-T) took a ride in a self-driving car.
