>3D-printed Wagyu beef
日本研制∑　出3D打印和牛肉

Scientists based in Japan's Osaka University have found a way to 3D print Wagyu beef in a lab — a step they believe will one day help make widely available and sustainably produced cuts of cultured meat that closely resemble the original products.
日本大阪大学的科学家日前在实验室里成功3D打印出了和▼牛肉，科学家相信这一进展将有助于未来研制出被广泛食用且可♀持续生产、酷似真ㄨ肉的人造肉。

By isolating beef cells, the scientists organized how the muscles, blood vessels, and fat should be stacked. The researchers then shaped these tissues into the form of a steak using a technique called 3D bioprinting, where cell structures can be layered to resemble real tissues in living things.
通过分离牛肉细胞，科学家理清了肌肉♀、血管和脂肪的分◥布规律，然后用3D生物打印技术将这些牛肉组织做成一块牛排的形状，通过对细胞结构进行分层使得产品ぷ酷似真▓和牛肉。

The researchers believe that proving that a Wagyu steak can be accurately 3D-printed could be a big step toward a sustainable future where cultured meat can be created that closely resembles existing products. Its origins from real meat also distinguish it from plant-based options, like those created by Beyond Meat and Impossible Foods.
研究人员认为，证实和牛排能被3D打印是迈向未来可持续√生产类真肉人造肉的重大一步。因为3D打印牛排的源头来自真肉，这也使其有别于Beyond Meat和Impossible Foods等公司■生产的人造素食牛肉。

>Pandemic leave ended for unvaccinated staff
美航:未接种疫苗不批新冠病假

American Airlines said on Friday it would not provide special leave from next month to unvaccinated employees who have to quarantine due to COVID-19.
美国航空公司9月3日表示，从下月开始，将不会为因新冠疫情而需要隔离〗的未接种疫苗的员工批准新冠肺炎病假。

Unvaccinated workers will have to use their sick time or medical leave if they miss work due to the disease, it said.
任何未接种疫苗但因新冠疫情而缺勤的员工需要使用他们的常规□　病假。

"Given there is an FDA-approved vaccine, pandemic leave will only be offered to team members who are fully vaccinated and who provide their vaccination card to us," the carrier said in a memo to staff seen by Reuters.
据路透社报道△，美国航空公司在发放给员工的备忘录中说："鉴于美国食品药品监督管理局〓已批准了新︽冠疫苗的接种，新冠肺炎病假将只提供给已完成疫苗接种并提供疫】苗接种卡的员工。"

The move comes after United Airlines last month became the first US carrier to require vaccinations for all domestic employees.
上个月，美国联合航空公司成为第一家∏要求所有国内员工接种疫苗的美国航空公司。

Separately, Alaska Air said on Friday that it had stopped special pay for unvaccinated employee absences due to COVID-19 infection or suspected exposure.
此外，阿拉◥斯加航空公司9月3日表示，已停止向未接种疫苗但感染◣新冠病毒或接触可疑人员的员工发放病假特别工资。

The airline has mandated vaccination for all new hires and will pay $200 to employees who provide proof of vaccination.
该航空公司已要求所有新员工接种疫苗，并将向提供疫苗接种证明的员工支付200美元。
