  • If you are not satisfied with the shape of your nose, blame it on climate, not your parents or grandparents.对自己的鼻子形状不满意?不要怪父母或祖父母,怪气候吧。In a study published this week in the journal PLOS Genetics, researchers from the Pennsylvania State University found that human noses may have been shaped, at least in part, by a long process of adaptation to local climate conditions.美国宾夕法尼亚州立大学的研究人员发现,人类鼻子的形状至少部分是由当地气候长期塑造而形成的。这项研究本周发表在美国《科学公共图书馆·遗传学》杂志上。Generally, wider noses are more common in warm and humid climates, while narrower noses are more common in cold and dry climates, it said.大体上,温暖湿润地区的人鼻子较宽,而寒冷干燥地区的人鼻子较窄。The findings were based on an examination of the size and shape of noses on people with West African, South Asian, East Asian, or Northern European ancestry.研究人员分析了西非、南亚、东亚、和北欧血统的人鼻子的大小与形状。The researchers looked at the width of the nostrils, the distance between nostrils, the height of the nose, nose ridge length, nose protrusion, external area of the nose and the area of the nostrils by using 3D facial imaging.借助3D面部成像技术,研究人员观察了鼻孔宽度、鼻孔间距离、鼻子高度与鼻梁长度、鼻子突出程度、鼻子外部区域、和鼻孔区域等。It showed that the width of the nostrils is strongly correlated with temperature and absolute humidity, but not the result of a random process called genetic drift.结果显示,鼻孔宽度与被称为基因漂移的随机过程无关,而与温度和绝对湿度等气候特征强相关。One purpose of the nose is to condition the air that we breathe, to ensure that it is warm and moist when it reaches the lungs, which helps to prevent infections.鼻子的一个功能是调节吸入的空气,让空气在进入肺部时变得温暖、湿润,帮助预防感染。The current study found the narrower nostrils seem to alter the airflow so that the mucous-covered inside of the nose can humidify and warm the air more efficiently.目前的研究发现,窄鼻孔可以改变气流,因此分泌有粘液的鼻腔能够更有效地湿润和温暖吸入的空气。;It was probably more essential to have this trait in cold and dry climates,; it said.研究报告写道:“这可能对干冷气候中的人们更重要。”;People with narrower nostrils probably fared better and had more offspring than people with wider nostrils, in colder climates. This lead to a gradual decrease in nose width in populations living far away from the equator.;“在较寒冷的气候中,较窄鼻孔的人可能比较宽鼻孔的人过得更好一些,有更多的后代。这导致远离赤道的人群鼻子逐渐变窄。”The nose has had a complex evolutionary history, however, and researchers suspected that additional factors, such as cultural preferences when picking a mate, have also played a role in shaping the nose.鼻子演化历史较为复杂。研究人员猜测,可能也有其他因素对鼻子的形状发挥作用,比如对鼻子大小的择偶偏好。Investigations into nose shape evolution and climate adaptation may have medical as well as anthropological implications.对鼻子形状演化历史和气候适应性的研究也有医学和人类学意义。Studies of human adaptation are essential to our understanding of disease and yield insights into why certain conditions, such as sickle cell anemia, lactose intolerance or skin cancer, are more common in certain populations.人类进化的相关研究对我们理解疾病,以及深刻了解为什么特定病症(比如镰状细胞性贫血、乳糖不耐症、和皮肤癌)在某些人群中更常见非常重要。The researchers said that it may be worth investigating whether the shape of the nose and the size of the nasal cavity impact one#39;s risk of contracting a respiratory disease when living in a climate that is different from one#39;s ancestors.研究人员表示,当人们生活在与祖先不同的气候中时,鼻子的形状和鼻腔的大小是否能影响一个人患上呼吸疾病的风险,这也许值得研究。 /201703/500436。
  • Has the razza del ratto (rat race) got you down? Is life too febbrile (hectic) where you live?大城市里的疯狂竞争令你沮丧了吗?你居住之处的生活太忙乱了吗?But are you worried you don’t have enough contanti (cash) to live a more peaceful life?还是你担心自己没有足够的钱去过更平静的生活?Then you might be interested in the Italian hillside village of Bormida, which is about to offer a payment of 2,000 (,175) and rents as low as a month to reverse its declining population.那么,你也许会对意大利尔米达的一个山坡上的小城感兴趣。这个小城打算付2000欧元(2175美元),且把每月房租降低至50美元来扭转其人口衰退的局面。Bormida, located in the mountainous Liguria region – Genoa, had declined to 390 residents in 2014, when the current mayor, Daniele Galliano, took office, according to the local newspaper.据当地报纸报道,尔米达坐落于山脉众多的利古利亚地区热那亚市,2014年尔米达的人口已削减至390人,就在那个时候现任市长达尼埃莱·加利亚诺上任。Spurred by visions of a ghost town, Galliano began measures to reverse the decay.在受到幽灵镇想法的刺激后,加利亚诺开始采取措施扭转人口衰退的局面。But with only four people added, he decided more-enticing measures were needed, hence the subsidies, which also include a 0-a-month rent for larger homes.然而小城人口只增加了4人,于是他认为需要采取更有吸引力的措施,因此就提出了补贴政策,其中还包括把大房子的租金定为每月130美元。;We couldn#39;t rent them at market value, so we chose a symbolic number and the requests abounded: the important thing was to repopulate the village,; Galliano said.“我们不会以市场价出租房屋,所以我们选择了一个象征性的数字并提出了许多要求:最重要的一点就是要使人们重进住进村子里,”加利亚诺说道。According to Britain’s Guardian newspaper, details of the offer still needed to be settled and approved by the local council, Galliano wrote on his Facebook page. But if the proposal is passed, anyone who moves to Bormida will be given 2,000.据英国卫报报道,加利亚诺在他的脸书主页上写道,该提议的细节还需要由当地委员会确定并批准。但是如果该提案通过了,那么任何搬进尔米达的人都会拿到2000欧元。According to Cosmopolitan magazine, the village has one main street, four restaurants (hey, this is Italy), a bed and breakfast and a post office that opens only three days a week. Much of the architecture dates back to 1200s.据时尚杂志报道,这个村子有一条主街、四家餐馆(咳,这是意大利呀)、一家简易旅馆(住宿加早餐)和一个邮局,而邮局一周只营业三天。这个村子里的多数建筑都可追溯至13世纪。“There is nothing much to do here,” Oddone Giuseppe, manager of one of the restaurants, told the Guardian. “But life is so simple and natural, we have forests, goats, the church, and plenty of good food. Life would definitely be free of stress.”“这里没有太多的事情要做,”一家餐馆的经理奥德奈·朱塞佩告诉卫报。“但是这里的生活简单又放松。我们有森林、山羊、教堂,还有许多美味的食品。在这里生活一定会毫无压力的。” /201705/509941。
  • While walking across an open, grassy field, I became excited as my hand swooped toward the ground like an eagle attacking its prey.我走在一片开阔的草地上,就像老鹰捕食一样,我兴奋地将手朝草地里抓去。I picked up half of a bill. I continued to walk around looking for the other half but thought to myself it would be impossible to find it on such a windy day.我捡到了半张5美金,我继续向前寻找另外半张,但是在这样一个大风天,我感觉到应该是找不到了。As I lifted my head, I spotted the other half of the bill tangled in crabgrass.我抬头时发现,另外一半缠在一片杂草中。Somehow, finding two halves of a ripped bill felt better than working for a twenty.捡全一张撕破的5美金比挣到20美金,在某种程度上还要让我开心~ /201705/507941。
