Sweet potato helps tackle child malnutrition 紅薯可幫助應對兒童營養不良
Work starts on British polar research ship 英國新極地科考船正式開建
文字稿
From the red soil of Uganda, these farmers are unearthing an unlikely solution to a silent killer. Orange flesh sweet potatoes are rich in beta-carotene, needed to prevent Vitamin A deficiency; an affliction that leads to the death of an estimated 670,000 people globally every year. In Uganda 32% of children under five are estimated to suffer from Vitamin A deficiency. Scientists here are hoping to change that. Through a technique called biofortification, they interbred sweet potatoes from across the world to produce the most nutrient-rich variety.
在烏幹達，這些農民們正在從紅壤裡挖掘看似不可能卻有望治療一種致病“隱形殺手”的良方。橙瓤紅薯富含預防維生素A不足的β-葫蘿卜素。缺乏維生素A是困擾並導致每年全球約67萬人死亡的病癥。據估算，在烏幹達有32%的五歲以下兒童缺乏維生素A。這裡的科學傢們希望能改善該狀況。通過利用生物強化技術，他們將產自世界各地的紅薯雜交繁殖，從而種植出最富有營養的紅薯品種。
Work has officially begun on a new British polar research ship, the RRS Sir David Attenborough, named after the broadcaster and naturalist. The vessel is perhaps best known for the online vote to name it, which saw the public choose ‘Boaty McBoatface’ after a social media campaign hijacked the poll. Once complete, the vessel will conduct crucial scientific research in both the Arctic and the Antarctic.
以播音員及博物學傢大衛·艾登堡命名的英國最新極地科考船“皇傢考察艦大衛·艾登堡爵士號（RRS Sir David Attenborough）”已正式開工建造。圍繞這艘艦艇最令人熟知的事件想必應該是一次網絡投票命名活動，這次民意調查被一股社交媒體風潮搶瞭風頭，導致公眾選擇將其命名為“小船·麥克船臉號（Boaty McBoatface）”。這艘船一旦完工會立即在北極與南極開展至關重要的科學考察活動。
