Flying electric taxis

會(huì)飛的電動(dòng)出租車

Long seen as something of a fantasy， flying taxis are getting serious. Several firms around the world will step up test flights with the aim of getting their aircraft certified for commercial use in the following year or two. Joby Aviation， based in California， plans to build more than a dozen of its five-seater vehicles， which have a 150-mile range. Volocopter of Germany aims to provide an air-taxi service at the 2024 Paris Olympics. Other contenders include eHang， Lilium and Vertical Aerospace.

長期以來，會(huì)飛的出租車在某種程度上被視為一個(gè)幻想，但是這件事正在成真。世界各地的幾家公司正在加緊試飛，目標(biāo)是在接下來的一兩年內(nèi)讓他們的飛機(jī)獲得商業(yè)用途認(rèn)證?？偛课挥诩永Ｄ醽喌腏oby Aviation計(jì)劃制造十多輛五座汽車，這些汽車的航程為150英里（約241千米）。德國 Volocopter 旨在為 2024 年巴黎奧運(yùn)會(huì)提供空中出租車服務(wù)。其他競爭者包括 eHang、Lilium和Vertical Aerospace。

Delivery drones

運(yùn)貨無人機(jī)

Wing， a sister company of Google， has been doing test deliveries in America， Australia and Finland and will expand its mall-to-home delivery service， launched in late 2021. Dronamics， a Bulgarian startup， will start using winged drones to shuttle cargo between 39 European airports. The question is： will the pace of drone deliveries pick up—or drop off？

谷歌的姐妹公司W(wǎng)ing一直在美國、澳大利亞和芬蘭做運(yùn)貨無人機(jī)的交付測試，并將擴(kuò)大其于2021年底推出的商場到家送貨服務(wù)。保加利亞初創(chuàng)公司Dronamics將開始使用有翼無人機(jī)在39個(gè)歐洲機(jī)場之間運(yùn)送貨物。問題是：無人機(jī)交付的速度會(huì)加快還是下降？

Personalized nutrition

個(gè)性化的營養(yǎng)搭配

Diets dont work. Evidence is growing that each persons metabolism is unique， and food choices should be， too. Enter personalized nutrition： apps that tell you what to eat and when， using machine-learning algorithms， tests of your blood and gut microbiome， data on lifestyle factors such as exercise， and real-time tracking of blood-sugar levels using coin-sized devices attached to the skin.

節(jié)食不起作用。越來越多的證據(jù)表明，每個(gè)人的新陳代謝都是獨(dú)一無二的，對食物選擇也應(yīng)該如此。輸入個(gè)性化營養(yǎng)：使用機(jī)器學(xué)習(xí)算法告訴你吃什么和什么時(shí)候吃的應(yīng)用程序、血液和腸道微生物組測試、運(yùn)動(dòng)等生活方式因素的數(shù)據(jù)，以及使用能粘貼在皮膚上的硬幣大小的設(shè)備，來實(shí)時(shí)跟蹤血糖水平。
