Don’t have a cow, man — just have a steak.

老兄，别吃牛肉了，吃块(人造)牛排吧。

The world’s first lab-grown, slaughter-free steak has been unveiled in Israel — although its makers¹ say the taste needs some work before it can be served up to the public, according to new reports.

据最新报道，世界上第一块实验室培育的无屠宰牛排日前在以色列亮相，尽管牛排制造者表示口味还需要一些改进，才能向公众售卖。

“It’s close and it tastes good, but we have a bit more work to make sure the taste is 100 percent similar to conventional meat,” Didier Toubia, the co-founder and chief executive of the start-up Aleph Farms, told The Guardian².

创业公司Aleph Farms的联合创始人兼首席执行官迪迪埃.图比亚告诉《卫报》："牛排味道很好，很接近(传统肉类)，但我们还要做点改进，确保它的味道和传统的肉类百分之百相似。”

“But when you cook it, you really can smell the same smell of meat cooking.”

“但是当你烹饪的时候，你真的可以闻到同样的肉的味道。”

The steak is grown from a few cells extracted painlessly from a living cow — and then nourished and grown to replicate³ muscle tissue, the Jerusalem Post reported.

据《耶路撒冷邮报》报道，这块牛排是通过在活牛身上无痛提取几个细胞培养后复制肌肉组织而成的。

The prototype costs $50 for a small strip — but Toubia told the Guardian that price is “not insane.”

这份样本牛排每小条售价50美元，但图比亚告诉《卫报》，这个价格“并不疯狂”。

It’s a bargain compared to the first lab-grown beefburger, which cost more than $280,000 when it was released in 2013 — and Toubia said the cost should eventually come down as production is moved from the lab to a commercial facility.

这与实验室培育的第一个牛肉汉堡相比，已经很便宜了。2013年，第一个牛肉汉堡上市时，售价超过28万美元。图比亚说，随着生产从实验室转移到商业化，这种牛排的成本最终应该会下降。

The company is also working to increase the thickness of the steak — with the help of Professor Shulamit Levenberg, an expert in tissue engineering at the Technion, Israel’s Institute of Technology.

在以色列理工学院技术研究所组织工程专家舒拉米特.利文伯格教授的帮助下，该公司还努力增加牛排的厚度。

Several recent studies have found that large reductions in meat-eating are needed to cut greenhouse gas emissions⁴ and stave off climate change, the Guardian reported.

据英国《卫报》报道，最近的几项研究发现，为了减少温室气体排放和延缓气候变化，需要大量减少肉食。

Still, Aleph Farms isn’t aiming to replace traditionally raised, grass-fed cattle — just factory farms, Toubia told the paper.

不过，图比亚对该报表示，Aleph Farms并不打算取代传统工厂化农场饲养的食草牛。

“We are not against traditional agriculture,” he said. “The main issue today is with intensive, factory farming facilities, which are very inefficient⁵ and very polluting and have lost the relationship to the animal.”

他说：“我们并不反对传统农业，如今的主要问题是集约化、工厂化养殖设施的效率非常低，污染非常严重，已经失去了与动物的关系。”
