Lab-grown steaks the size of a credit card have grown and eaten for the first time, according to an Israeli company.
Cell culture meat takes samples from live animals and turns them into food using scientific methods and incubation.
A race is evolving between technology companies to be the first to create a successful product.
Previous attempts have seen how minced meat and chicken nuggets were made, but no complex animal tissue structures, such as steaks, were made from them.
Biopharmaceutical company Aleph Farms claims to have found a way to produce meat without slaughter meat with the same texture as the authentic alternative.
The technology comes at a time when a growing population of vegans, vegetarians and animal rights activists are waging an ethical war against eating meat.
Livestock farming and agriculture account for large amounts of available land and make an important contribution to the emission of greenhouse gases.

As part of a video function for the Wall Street Journal, Jason Bellini visited the base of the company on the outskirts of Tel Aviv.
Two incubators, called Alberto and Gertrude, are where different petri dishes grow with cells from two cows that are still alive.
They imitate the conditions in a cow to produce as accurate cells as possible.
A complex series of tests then produces four different types of animal tissue; supporting cells, fat cells, blood vessel cells and muscle cells.
These are then combined to form a complex shape and form a full-fledged steak after three weeks.
Technology for cruelty-free meat & # 39; is still under development and the company claims it would cost about $ 50 for a single piece of the thin steak.
Didier Toubia, CEO of Aleph Farms, said that the taste and taste are 60 percent of the desired goal and that the product will not be available on the market for more than two years.
& In theory, we can say that you could eat bison meat without killing bison. You could eat whale without harming whales, "says Jan Dutkiewicz, a researcher at Johns Hopkins University.
The development of technology has progressed steadily, with Just Food, a San Francisco-based company working on the use of vegetable protein to make meat substitutes.
The company claims that its non-chicken nuggets will be available before the end of 2018 and today announced a partnership to develop and market a cell grown version of the more luxurious Japanese beef Wagyu.
Dear loved ones have had the opportunity to experience umami Wagyu and we hope that this collaboration allows more restaurants to share Toriyama beef and the story in a new, exciting way, & # 39; said co-founder and CEO Josh Tetrick in a statement.
The meat industry is one of the most dominant sectors in the world and requires a huge amount of resources.

Scientists from the University of Oxford and the Swiss Agricultural Research Institute, Agroscope published a paper earlier this year in which 40,000 farms and 1,600 processors, types of packaging and retailers in 119 countries were examined.
The study was the most comprehensive analysis to date of the damage that agriculture causes to the planet.
It also assessed how different production processes and geographical areas lead to different environmental impacts for 40 important foods.
They discovered that without consumption of meat and dairy products, agricultural land in the world would be reduced by 76 percent.
This corresponds to the size of the US, China, European Union and Australia together, and there would still be enough food to feed the world.
A small number of producers create much of the impact: only 15% of beef production creates about 1.3 billion tonnes of CO2 equivalents and uses around 950 million hectares of land.

HOW IS TEST MEAT IN A LABORATORY?
& # 39; Test Tube Meat & # 39; is a term used to describe meat products that are grown in a laboratory
& # 39; Test Tube Meat & # 39; is a term used to describe meat products that are grown in a laboratory.
They are made by harvesting stem cells from the muscle tissue of live cattle.
The cells, which have the ability to regenerate, are then grown in a nutritional soup of sugars and minerals.
These cells are then left to develop skeletal muscle in bioreactor tanks that can be harvested in just a few weeks.
Lab-grown beef was first made by Dutch scientists in 2013. A test-house burger was served in a restaurant in London to two food critics.
In March 2017, Memphis Meats from San Francisco successfully grew poultry meat from stem cells for the first time.

A study by a Harvard scholar exacerbated the impact of agriculture on the world.
It turned out that if all people on earth became vegan, the world would be almost halfway to meet the lofty climate change targets set out in the Paris Agreement.
These targets state that the temperature in the world must be limited to an increase of 1.5˚C (2.7 ° F) by 2030.
Methane and nitrogen oxide are produced in large quantities by livestock and make an important contribution to the greenhouse effect.
Animal rights activists, scientists and nature conservationists have long advocated a reduction in global consumption of meat and dairy products to reduce the impact on the environment.
Although it is not enough to achieve climate change targets on your own, animal husbandry still has a key role to play in helping to achieve the ambitious goals, scientists have insisted.
A study by Harvard found that if all people on earth stopped eating animal products, the fall in global greenhouse gas emissions would be insufficient to reach the temperature rise of 1.5˚C by 2030, as outlined in the Paris Agreement ( stock)
Previous studies suggested that reducing the consumption of meat and dairy products also offers a number of additional benefits, such as the preservation of biodiversity and the improvement of human health.
The current livestock in the world consists of approximately 28 billion animals and is the largest source of two important greenhouse gases: methane and nitrogen oxide.
The production of methane in particular is difficult because it has an 85 times greater greenhouse effect than carbon dioxide over a period of 20 years.
The emission of methane from livestock farming is expected to increase by 60 percent in 2030.
Getting proteins from vegetables, grains or meat alternatives instead of animals would drastically reduce the risk of non-achievement of temperature targets, researchers said.

Dominika Piasecka, spokesman for The Vegan Society, told MailOnline: "We welcome any reduction in animal suffering and laboratory meat can be a friendlier alternative for those who still want to eat meat.
Sooner or later the growing world population will be forced to eat less meat because the bio-industry is not sustainable.
Instead of waiting until this happens, it is more beneficial for the animals and the planet to find an alternative for those who are not yet ready to become vegan.
& # 39; There are benefits for the environment and a potential contribution to combating hunger in the world through meat from the laboratory.
& # 39; On the other hand, the debate about whether this is the future of food can be seen as a distraction from the real problem of promoting plant nutrition as a valid solution here and now. & # 39;
Driving the burgeoning industry has created a new era in US food surveillance, and there is currently no existing legislation to process meat from animals that have not been killed.
Last month it was announced that the FDA and the USDA will have joint control over the sector.
The American state of Missouri has also introduced a legislature that says that a food can not be called meat if it does not come from an animal.
This was received with open arms by farmers and ranchers in the US who believe that the world of cell-grown food and meat threatens their livelihood.
Kevin Kester, chairman of the National Cattlemen & # 39; s Beef Association, said that the Missouri law is a step in the right direction.
He added: "There will be other states that I have been told will do the same efforts to clarify what meat defines.
We want to ensure that we have a level playing field in the field of marketing and safety inspection.
& # 39; We do not know what the products are yet. & # 39;
WHAT IS THE PARIS AGREEMENT?
The Paris Agreement, which was signed for the first time in 2015, is an international agreement to control and limit climate change.
He hopes to keep the global average temperature rise below 2 ° C (3.6 ° F) and to make further efforts to limit the temperature rise to 1.5 ° C (2.7 ° F).
It seems that the more ambitious goal of reducing global warming to 1.5 ° C (2.7 ° F) is more important than ever, according to previous research that claims that 25 percent of the world has a significant increase in the drier circumstances.
In June 2017, President Trump announced his intention for the US, the world's second largest producer of greenhouse gases, to withdraw from the agreement.
The Paris Agreement on Climate Change has four main objectives with regard to reducing emissions:
1) A long-term goal to keep the global average temperature rise well below 2 ° C above the pre-industrial level
2) strive to limit the increase to 1.5 ° C as this would significantly reduce the risks and the consequences of climate change
3) Governments agree that global emissions should be achieved as soon as possible, knowing that this will take longer for developing countries
4) Then take rapid reductions in accordance with the best available science
