The older I get the more I believe a law of equivalent exchange (like in Fullmetal Alchemist) actually does apply to everything in existence, it blurs the line between thermodynamics and karma, but only the physical side of it is convincingly measurable.
New study suggests that lab-grown meat produces up to 25 times more CO2

#142Just going by the headline, (I don't have time to read another click bait) if it is indeed true, this is to be expected. The one thing that nature is good at is extraordinary degree of efficiency when using energy fine tuned by evolution. No 'artificial' processes will beat that efficiency. Unless you're looking for a significantly worse quality of meat, lab grown meat is never going to be equivalent to real meat, both in terms of quality, and in terms of energy utilization.

#143This is an expected result if you extrapolate from an early R&D stage process to a global scale, but it doesn’t mean that it’s not worth pursuing more sustainable routes to the mass production of animal muscle. And that’s really what the underlying goal is here - don’t fall for the false dichotomy of “farmed” vs “lab-grown” - factory farms are essentially process development labs. How efficiently can you convert land…
A minor addition, the agriculture industry had an enormous amount of subsidies and decades of research and work at the global scale to reach the current state. Comparing an early prototype with an industry of this kind is disingenuous at best.
No, its called a benchmark and tells you how much you have to do to reach the goal you are ostensibly trying to reach. Its useful not disingenuous. Now if someone says this is the final word on lab meat, that would be disingenuous.

#144I want to eat meat from chickens and cows that had good, happy lives, eating the healthiest most natural form of their diet possible. I don't want lab grown meat, the concept is disgusting. As it is our food is too processed and industrial. Maybe we can focus on mixed farming instead https://www.earth.com/news/mixed-farming-could-increase-food...
The question to ask is: can everyone eat meat from animals that had good happy, lives? Does that scale to everyone?
Yes if they eat a lot less of it. You probably can't raise animals as efficiently (especially in terms of land required) while keeping them happy. The difference will be reflected in the cost to the consumer - ethical meat is more expensive[1].
Whenever these conversations crop up, the idea that we might need to eat less meat to achieve ethical or environmental goals seems to be unthinkable to many commenters. The recent fad diets that focus on consuming tons of animal protein have really muddled the water as well since they seem to imply that you can't eat healthy while eating less meat. I think that's why you see so much enthusiasm for lab-grown meat.

#145In my experience (in a different field), it is common for researchers to acknowledge the source of their funding. In particular, researchers are keen to acknowledge funding from government grants, as this is perceived to be helpful in applying for future research grants. I glanced through the paper and I could not find any mention indicating who funded that study. I'm also very sceptical of single studies that suppor…
From my experience conflict of interests and funding sources is a disclosure enforced by the journal
Being a preprint, this is obviously neither peer reviewed nor vetted by a journal.
In this case, I cannot deduce what journal they plan on submitting to (if they plan to at all)

#146I’m surprised at the skepticism here on HN. Was everyone this skeptical / glib when the (insert technology) was useless when it was invented? Anyone seen the efficiency of a solar panel in 1970? Factory farming is a real problem to solve.
There are people who have a genuinely held belief that they are being "attacked" and liberals will force them to eat "unnatural" lab grown meat and "bugs". There are lots of those people here on HN and they have commented plenty on similar articles to this.
It's similar in vein to the people who were absolutely convinced that Biden was preparing a team to confiscate gas stoves and responded by.... running their gas stoves on full burn for no reason, as a "protest".
I have no moral qualms with raising, killing, and eating an animal. If lab grown meat is tasty, safe, and affordable, it will be great.

I think the fundamental problem is keeping the huge bio tanks hermetically clean. The cleaning process is very energy intensive as is the medium growing process. One way to cut cost would be to introduce small cells that seek out and destroy pathogens. We could design a bio tank organ that creates these cells by eating some of the growth medium. Also instead of using a medicine grade medium we could use organic sacks…
Not sure why you’re getting downvoted but your satirical take is kind of exactly what I’m talking about. We might end up reverse engineering an immune system to make it work at scale, because contamination resistance actually is one of, if not the primary problem at large scale.

#148I would never eat processed manufactured meat. This is just another food category being converted to processed foods. Processed foods make you sick, weak and takes your life. Want a short unhealthy life? Eat processed foods. Pharma will be there for you to speed up your own efforts.

#149Earlier quoted context omitted.
Not disagreeing with you, but ultimately you have to ask the question: does this make sense? And look at the "why". What are you trying to optimize?
You may not care about the widespread cruelty to animals in meat production, but many people do.
But you may not care about possible future when I can not grow some chicken legally for my own consuming, but I appreciate eating animals as one of the most natural and beautiful things in my life.

#150Forget about lab grown meat: give me a bean that doesn't cause gas or other stomach irritation. We could eat beans 3 times a day and save the world while we're at it, all while saving money.
Isn't this the entire sales pitch of Beano?
