Cytera Cellworks aims to bring cell culture automation to your dinner plate

Cytera Cellworks hopes to revolutionize the so-called ‘clean meat’ industry through the automation of cell cultures — and that could mean one day, if all goes to plan, the company’s products could be in every grocery store in America.

Cytera is a ways off from that happening, though. Founded in 2017 by two college students in the U.K., Ignacio Willats and Ali Afshar, Cytera uses robotic automation to configure cell cultures used in things like growing turkey meat from a petri dish or testing stem cells.

The two founders — Willats, the events and startups guy and Afshar the scientist, like to do things differently to better configure the lab as well — like strapping GoPros to lab workers’ heads, for instance. The two came together at the Imperial College of London to run an event for automation in the lab and from there formed their friendship and their company.

“At the time, lab automation felt suboptimal,” Afshar told TechCrunch, further explaining he wanted to do something with a higher impact.

Cellular agriculture, or growing animal cells in a lab, seems to hit that button and the two are currently enrolled in Y Combinator’s Summer 2018 cohort to help them get to the next step.

There’s been an explosion in the lab-made meat industry, which relies on taking a biopsy of animal cells and then growing them in a lab to make the meat versus getting it from an actual living, breathing animal. In just the last couple of years startups like Memphis Meats have started to pop up, offering lab meat to restaurants. Even the company known for its vegan mayo products Hampton Creek (now called Just) is creating a lab-grown foie gras.

Originally, the company was going to go for general automation in the lab but had enough interest from clients and potential business in just the cell culture automation aspect they changed the name for clarity. Cytera already has some promising prospects, too, including a leading gene therapy company the two couldn’t name just yet.

Of course, automation in the lab is nothing new and big pharma has already poured billions into it for drug discovery. One could imagine a giant pharma company teaming up with a meat company looking to get into the lab-made meat industry and doing something similar but so far Willats and Afshar says they haven’t really seen that happening. They say bigger companies are much more likely to partner with smaller startups like theirs to get the job done.

Obviously, there are trade-offs at either end. But, should Cytera make it, you may find yourself eating a chicken breast one day built by a company who bought the cells made in the Cytera lab.

Twitter is purging accounts that were trying to evade prior suspensions

Twitter announced this afternoon it will begin booting accounts off its service from those who have tried to evade their account suspension. The company says that the accounts in question are users who have been previously suspended on Twitter for their abusive behavior, or for trying to evade a prior suspension. These bad actors have been able to work around Twitter’s attempt to remove them by setting up another account, it seems.

The company says the new wave of suspensions will hit this week and will continue in the weeks ahead, as it’s able to identify others who are “attempting to Tweet following an account suspension.” 

Twitter’s announcement on the matter – which came in the form of a tweet – was light on details. We asked the company for more information. It’s unclear, for example, how Twitter was able to identify the same persons had returned to Twitter, how many users will be affected by this new ban, or what impact this will have on Twitter’s currently stagnant user numbers.

Twitter was not able to answer our questions, when asked for comment.

The company has been more recently focused on aggressively suspending accounts, as part of the effort to stem the flow of disinformation, bots, and abuse on its service. The Washington Post, for example, said last month that Twitter had suspended as many as 70 million accounts between the months of May and June, and was continuing in July at the same pace. The removal of these accounts didn’t affect the company’s user metrics, Twitter’s CFO later clarified.

Even though they weren’t a factor, Twitter’s user base is shrinking. The company actually lost a million monthly active users in Q2, with 335 million overall users and 68 million in the U.S. In part, Twitter may be challenged in growing its audience because it’s not been able to get a handle on the rampant abuse on its platform, and because it makes poor enforcement decisions with regard to its existing policies.

For instance, Twitter is under fire right now for the way it chooses who to suspend, as it’s one of the few remaining platforms that hasn’t taken action against conspiracy theorist Alex Jones.

The Outline even hilariously (???) suggested today that we all abandon Twitter and return to Tumblr. (Disclosure: Oath owns Tumblr and TC. I don’t support The Outline’s plan. Twitter should just fix itself, even if that requires new leadership.)

In any event, today’s news isn’t about a change in how Twitter will implement its rules, but rather in how it will enforce the bans it’s already chosen to enact.

In many cases, banned users would simply create a new account using a new email address and then continue to tweet. Twitter’s means of identifying returning users has been fairly simplistic in the past. To make sure banned users didn’t come back, it used information like the email, phone and IP address to identify them.

For it to now be going after a whole new lot of banned accounts who have been attempting to avoid their suspensions, Twitter may be using the recently acquired technology from anti-abuse firm Smyte. At the time of the deal, Twitter had praised Smyte’s proactive anti-abuse systems, and said it would soon put them to work.

This system may pick up false positives, of course – and that could be why Twitter noted that some accounts could be banned in error in the weeks ahead.

Reached for comment, Twitter declined to answer our specific questions and said it could also not go into further details as that would give those attempting to evade a suspension more insight into its detection methods.

“This is a step we’re taking to further refine our work and close existing gaps we identified,” a spokesperson said. “This is specifically targeting those previously suspended for abusive behavior. Nothing to share on amount of accounts impacted since this work will remain ongoing, not just today.”
