It's amazing that they're farming stem cells for beef but not for human organs. It's also amazing that electrical impulses can be used to grow the stem cells which are in vitro (lab-grown) without using carbon.
This is really interesting. It would be great if scientists discovered a simple way to make this so that no animals had to be slaughtered for food. I was wondering if the cells would have the same nutrients in them, like protein, that "real" meat does. I agree with Sergio in that it might be very helpful to farm stem cells for human organs.
I thought this was very interesting. If they could make it something that a person could buy (not 330,000 dollars) then it would be an amazing new creation. If less animals could get slaughtered, then many more people will be happy because of no animal cruelty or slaughtering. Like Sergio and Molly said, it would be cool if they made human organs, but right now they would be very expensive also, so no one could purchase them to use if someone is sick.
That is really cool, but that would be a VERY expensive burger and not many people (almost none) will buy it until the prices are drastically changed. I can see why it is so expensive though, with only 20 dishes growing at once, and needing 3000 for each burger... It is amazing that NASA has already created fish nuggets grown in a lab, and because we have already created lab grown food, I am surprised it will not be until (an estimate of) 2082 when this becomes a regular thing. I also do not understand why they chose to grow the fish filet in mushroom broth, but there is probably a reason. I think it is amazing that there is such thing as a non-vegetarian (technically) burger that no cow or any mammal was killed for. Like everyone else has said, I think making human organs would be a very good idea. What is more important? Saving lives through new organs, or getting a environment friendly, meat free burger? Hmm...
I don't really think is a good idea because there could be all kinds of chemicals that they use to make it that isn't really in a "real" animal. AND it's not like every human that is born eats meat, some can be vegetarians or vegans.
This was really cool and interesting. This is really good for the animals because less get slaughtered, but it is really expensive and no one will buy it unless the prices go down, like WAY down. I also agree with Sofia about how not every human eats meat, and there are probably SOME bad chemicals in this.
This article shows how we can change our ways to help our planet. Like Nate said, barely anyone would buy that meat especially in this economy. The price will probably go down once it is studied more. It would be funny if in the future killing real animals would be unheard of. The amount of "would-be meat" he needs for one burger is shocking and may delay the time that these burgers would be in our everyday life.
Why are scientists trying to make meat from scratch? To make the engineered meat they still need to use stem cells from cows, and they still have to use electricity to stimulate the meat to grow in a lab which requires energy. Also high consumption of red meat can cause health problems. Besides, there are other sources of protein, like legumes, tofu, and nuts. Right now it will still take a long time before scientists can make meat that is edible, nutritious, low cost, easy to produce, and won’t harm animals or hurt the environment/atmosphere. They would also need to build huge labs to grow enough meat to feed the world.
Technically, the meat wouldn't have bad chemicals since it cultured/ in vitro/ lab grown. If a few bad chemicals got into the meat it would still be better than the meat we eat in current times. Many bad things are in the world's beef supply: 1. It was only recently discovered that finely textured beef (pink slimes) which is the name of left over meat chunks with ammonium hydroxide, was being used by 4 texan plants. 2. E. coli. (bacterium) 3. Salmonella (bacterium)
This is a cool article, but personally I don't think I'd want to eat lab-grown meat. Also, because it's not real meat, vegetarians could eat meat. How weird does that sound? I also think that they should lower the price on this meat.
This seems interesting and a very good idea. The only problem with the "Frankenburger" is that I don't know if it sounds appetizing. Personally, I don' t think I would eat it, though. This would be great for the Earth and for the safety of animals though. In Food Inc. we are talking about a "Meatless Monday" campaign, and this article reminded me about that. I disagree with David, and really think it is a good idea. Although you use stem cells, I doubt you would have to kill the whole cow, also it technically wouldn't be red meat because it is lab grown. I also agree with what Sergio pointed out that it would reduce E. coli and Salmonella cases. Also, a big market for the meat would be in India, where beef is outlawed due to the cow being a sacred animal. So thumbs up to Mark Post!
This would probably display mixed results. Because it isn't real meat, it could be eaten by vegetarians and pacifists, but some people don't like factories, and stuff made in them.
Eventually, when this is more "cost-effective", this will be the new "organic" meat. If this goes on to different animals, it could make a whole new meaning to "cage free".
If this does work, then it will probably take a long time, and when it does happen, if it does, it will probably take a long time for the lab-grown meat to completely replace real meat. I am kind of iffy about the whole thing. It doesn't say how long it takes the cells to grow to their maximum amount, but it probably takes a long time, and it takes a lot of them to actually make something out of them. Besides for shocking the cells, it doesn't seem like there is a good way to speed up the process, and for this whole idea to work, they would have to lower the price of the meat a lot. But if this does actually work, it will be very good for the animals and the environment. The article mentioned that the scientists are adding nutrients and stuff to the meat to make it healthier and just making adjustments to make it better, so if it does work, the scientists have to be careful, because if they change it too much, it won't be meat anymore, if it ever was in the first place.
This is both interesting, brilliant, disturbing, and downright disgusting. I think that it is a better alternative to animal cruelty and slaughtering, but I also have my doubts about the artificial meat. For example, does this have the actual amount of nutrients that you can find in actual animal meat? Are there any drawbacks/side-effects to this? It does, indeed, sound like a very interesting topic for us to think on, and do research on, but I don't think that this would be very popular with the public. (I'm not saying that I'm against completely diminishing animal slaughter and cruelty.)
Sergio, not all meat would have E. coli and things like that maybe because for example,some cows are fed thing they shouldn't really be eating, BUT some cows feed on grass. SO... not all cows could have E. coli. I think it is the way they are treated.
This is pretty interesting, but I don't think that it would be good to eat. Anything that is fake you have to watch out for. It would be good because you wouldn't have to slaughter animals.
I've never heard of stem cells before, and it was pretty intriguing to know that they divide and produce lost bones and muscles. But the lab-grown burgers are very expensive, they would have to find a more cost-efficient way to produce the meat. Also, would the meat have proteins in it, or just chemicals? They didn't really explain the health factor of the burgers...
This is a very interesting idea, and could potentially be used as a replacement for true animal meat. However, the amount of time estimated to drastically reduce the price to something reasonable is alarming. Due to recent technologies, I would have thought that it would have been very easy to replicate, driving the prices down.
I would not eat this stuff until they made filet mignon. I love filet mignon. Anyway, this beef concoction has a lot of hard competitors. They have to-meat (i.e. tofurkey) and real meat in the same market. On another note, they could save energy in the plant by just having solar panels. Everywhere. Also, wont the one cell that they took from the cow multiply, then those multiply etc. Why would they need to get more cells? I don't get it. I agree with Sergio that they should start with human organs. To do that though, they would need a willing patient come in for surgery to do something they aren't sure will even work. What if all the cells died and the patient went in for surgery for nothing. What a waste. I remember Jason's grandpa saying that brain and heart cells couldn't reproduce. If these scientists could modify these cell to be reproductive and grow these organs, then just imagine how many lives we could save!

WELL... before I said treated, but I also think it is the way they are fed.
This year India will become the world's third largest exporter of beef in the world, behind Brazil and Australia.
