The real success in this area is the Impossible burger. It's made mostly from peas and soy, with heme added to produce the bloody meat texture. The heme is made in a fermentation process not much more complex than brewing. Impossible has no problems with volume production - they sell through Burger King and WalMart. Growth rate about 85%/year.

Meat tastes good. Mushrooms taste good, but in a different way. You can want a perfect world, but it will never exist. Like it or don't, solving meat consumption and its effects on the planet is something we'll have to do. That probably involves a meaty substitute for meat.
Fungi make up one of three primary kingdoms of multicellular life. Mushrooms and other fungus have a variety of flavors already, and some of them are quite meat-like. Given fungus cells are more similar to animal than they are plant, it is possible that they can be selectively bred or engineered to taste more meat-like. I wouldn't be too dismissive of the potential here.

Also, there's a significant difference between "the process works on a small scale, and would work at a large scale if we can solve the reliability/consistency issues" versus Theranos' "the process literally isn't physically possible at any scale and we've been outright lying about it the whole time".
I think lab grown meat is closer to a Theranos type scam than most people realize. The problem with Theranos wasn’t that their tech didn’t work at any scale; it’s that blood drawn from finger capillaries is useless for most diagnostic tests that they claimed to do. It’s a very subtle problem that only investors with proper scientific advisors with diagnostic experience caught onto (aka all the biotech VCs, who stayed…
if we could replace the typical cattle pastures of today with this other system (basically the same idea without needing an organism that has a nervous system attached to it), I think we'll be closer to "making it"

I saw a farmer once demonstrate how their barn has an automatic ventilation system that kicks in when the temperature gets too high :)

When you compare mushroom dry weight, it is more like 10-25% protein. This is without any industrial processing.
Is that relevant? You don't eat dried mushrooms, even if you start with them you have to hidrate them a lot before they are any good.
We should measure the protein density at a meaningful state for consumption.
While you can eat some mushrooms fresh and dry, their water density when fried is somewhere in the middle. Closer to dry when processed.

Would you rather not exist at all if it saved you from dying?

Parent claims that because we don’t eat meat plain, this shows that it isn’t the meat that ”tastes good”, its the seasoning. The fallacy is that we could have applied the exact same logic to the seasoning: we don’t eat steak seasoning plain, therefore it isn’t the seasoning that tastes good, its the meat. By parent’s logic, meat both does and does not taste good. The resolution, which has always been obvious to every…
This is the same site where I read a post about making puree vegetables and freezing them as meal planning, because flavor was secondary to efficiency. So. . .

#108I'm not sure about chicken cells but my experience with growing human cells (WI-38 fibroblasts)[1] is that they want to grow in a monolayer. The way we grew them normally was in those roller bottles [2]: you have some tissue culture medium in the bottle (containing fetal calf serum, which is still required to grow mammalian cells AFAIK, another reason most of these companies can't do what they say) and other componen…
>when cells are touching each other, they stop dividing. I might be very stupid, but if this is a thing, how do we grow? Aren't, for example, bone cells always touching other cells?

> The cells want to grow in a one-cell-thick monolayer all over the inside of the bottle. What they won't do is to grow a double layer. This is because they have "contact inhibition" which is a major mechanism for preventing tumor-like growth: when cells are touching each other, they stop dividing. How does that work inside the human body, where presumably they do form 3D structures?

#110Key takeaway paragraphs for me: "But roller bottles aren’t just problematic due to their miniscule output. They’re also expensive and wasteful, according to numerous biopharma and cultivated-meat industry sources. Each flask is made from sterile, single-use plastic, which must be discarded or recycled once it has generated its 2 to 3 grams of tissue. Given that an ordinary 2-liter plastic drink bottle can easily weig…
I'm not sure the plastic use is super relevant at lab scale, as someone who has worked in lab cell culture the amount of plastic waste is enormous from all the single use individually packed sterile equipment. However, I don't think anyone is planning to scale up plastic single use tissue culture equipment to make food, its just not going to make economic sense. I can't comment on if they are claiming the current pro…
Seems pretty clear from TFA that unless WIRED are grossly misrepresenting facts, current product is made in a lab using roller bottles:
> WIRED sent a detailed list of questions to Upside based on our reporting. In an emailed statement, Chen, the company’s chief operating officer, claimed that our reporting contained a number of factual inaccuracies but did not directly address any of the points raised. Chen went on to say that Upside’s current process for producing chicken fillets was not one the company intends “to scale in its current form.”
> "All breakthrough innovations and transformative technologies, including scaling our cultivated meat products, will take time," Chen wrote in the emailed statement. "Cultivated meat is no exception. Not every research avenue, cultivator, or idea we explore will materialize exactly as we expected."
