Breakfast shop owner's gesture to child with cancer sparks wave of giving_我的网站

一 |     (ECNS) -- A breakfast shop owner in Hefei, Anhui Province, quietly slipped 100 yuan ($15) and two cups of soy milk into a food delivery order Monday after learning it was for a child undergoing chemotherapy. The act quickly went viral, inspiring pay-it-forward orders and nationwide support.    The order note requested an egg pancake “half without chili, half mildly spicy” for the four-year-old, who is receiving maintenance therapy for leukemia. Shop owner Wang Xianhuang, 33, confirmed the request, then added the cash gift — equal to the profit from 25 pancakes — before sending the meal.    Wang, 33, had opened the breakfast shop less than a month earlier. He said he wanted to help after thinking about the financial and emotional pressure on families caring for children undergoing chemotherapy. The cash gift was roughly equal to the profit from 25 of his low-priced egg pancakes.    After the story spread online, Wang’s revenue doubled the next day and customer traffic nearly tripled. Some patrons asked that meals be given to delivery riders or sanitation workers instead. Wang later shut down some delivery channels to manage demand, refused donations and pledged to return anonymous transfers, saying he would use part of his profits to support workers in his community.    (By Intern Yang Hongran, Zhang Dongfang)                    。    这项研究是由美国能源部布鲁克海文国家实验室和纽约冷泉港实验室的研究人员进行的。他们从一种被称为Lemna japonica的现有浮萍开始，向其添加了多个基因，这些基因已经被认为可以驱动其他植物的燃料生产和储存。在被描述为推/拉/保护效应中，其中一个基因推动（增加）脂肪酸的生产，其中一个基因将这些脂肪酸拉（组装）成三酰甘油油，另一个基因通过在植物组织中涂抹油滴来保护它们免受环境的降解。因此，工程浮萍积累的油几乎占其干重生物量的10%，据说这比该植物的野生对应物的积累率增加了100倍。

二 | 它的油产量是当今最大的生物柴油来源大豆的7倍以上。

三 | 然而，与大豆不同的是，浮萍作物不会占用农田，因为它们将被种植在大型容器或池塘中。

四 | 事实上，科学家们建议，浮萍作物可以种植在养猪场和家禽场的液体废物径流中，这些植物将通过从水中吸取多余的营养物质来帮助清理。一个挑战在于，通常情况下，推动脂肪酸生产的基因也会阻碍植物生长。为了解决这个问题，"推动"基因与另一个被称为启动子的基因配对，后者通过向水中添加一种特定的化学诱导剂而被激活。首席科学家，布鲁克海文生物化学家John Shanklin说：“加入这个启动子可以使推动基因保持关闭，直到我们加入诱导剂，这使得植物在我们开启脂肪酸/石油生产之前可以正常生长。

五 | ”研究人员现在正在研究种植浮萍并从中提取商业规模的油的方法。关于这项研究的一篇论文最近发表在《植物生物技术杂志》上。
