>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.
日本大阪大學(xué)的科學(xué)家日前在實(shí)驗(yàn)室里成功3D打印出了和牛肉，科學(xué)家相信這一進(jìn)展將有助于未來研制出被廣泛食用且可持續(xù)生產(chǎn)、酷似真肉的人造肉。

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.
通過分離牛肉細(xì)胞，科學(xué)家理清了肌肉、血管和脂肪的分布規(guī)律，然后用3D生物打印技術(shù)將這些牛肉組織做成一塊牛排的形狀，通過對細(xì)胞結(jié)構(gòu)進(jìn)行分層使得產(chǎn)品酷似真和牛肉。

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.
研究人員認(rèn)為，證實(shí)和牛排能被3D打印是邁向未來可持續(xù)生產(chǎn)類真肉人造肉的重大一步。因?yàn)?D打印牛排的源頭來自真肉，這也使其有別于Beyond Meat和Impossible Foods等公司生產(chǎn)的人造素食牛肉。

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

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.
美國航空公司9月3日表示，從下月開始，將不會(huì)為因新冠疫情而需要隔離的未接種疫苗的員工批準(zhǔn)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.
任何未接種疫苗但因新冠疫情而缺勤的員工需要使用他們的常規(guī)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.
據(jù)路透社報(bào)道，美國航空公司在發(fā)放給員工的備忘錄中說："鑒于美國食品藥品監(jiān)督管理局已批準(zhǔn)了新冠疫苗的接種，新冠肺炎病假將只提供給已完成疫苗接種并提供疫苗接種卡的員工。"

The move comes after United Airlines last month became the first US carrier to require vaccinations for all domestic employees.
上個(gè)月，美國聯(lián)合航空公司成為第一家要求所有國內(nèi)員工接種疫苗的美國航空公司。

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，已停止向未接種疫苗但感染新冠病毒或接觸可疑人員的員工發(fā)放病假特別工資。

The airline has mandated vaccination for all new hires and will pay $200 to employees who provide proof of vaccination.
該航空公司已要求所有新員工接種疫苗，并將向提供疫苗接種證明的員工支付200美元。

Amazon founder Jeff Bezos has reportedly invested in a newly formed startup aimed at reversing the process of biological aging.
據(jù)報(bào)道，亞馬遜創(chuàng)始人杰夫?貝佐斯投資了一家新成立的初創(chuàng)公司，該公司主攻如何逆轉(zhuǎn)生物衰老過程。

Altos Labs, founded earlier this year by Russian billionaire Yuri Milner, has already hired several leading longevity scientists in order to develop a radical form of biological reprogramming technology that would rejuvenate cells and allow humans to live up to 50 years longer.
今年早些時(shí)候由俄羅斯億萬富翁尤里?米爾納創(chuàng)立的阿爾托斯實(shí)驗(yàn)室已經(jīng)聘請了幾位領(lǐng)先的長壽科學(xué)家，以開發(fā)一種激進(jìn)的生物重編程技術(shù)，使細(xì)胞恢復(fù)活力，使人類壽命延長50年。

Bezos stepped down as CEO of Amazon in July.

Bezos has funded anti-aging research before — in 2018 he invested in Unity Technologies, a biotech company whose goal is to make anti-aging therapies.
貝佐斯之前也曾投資于抗衰老研究。他在2018年投資了生物技術(shù)公司聯(lián)合科技，該公司的目標(biāo)是研發(fā)抗衰老療法。
