遵义妇幼保健院疏通输卵管堵塞贵州天伦不孕不育医院开了多少年了Scientists have found what they think is the oldest fossil on Earth, a remnant of life from 3.7 billion years ago when Earth#39;s skies were orange and its oceans green.近日,科学家发现了距今约37亿年前的微生物菌席化石,当时地球天空还是橘色的,大海也还是绿色的。他们认为这是迄今为止发现的最古老的化石。In a newly melted part of Greenland, Australian scientists found the leftover structure from a community of microbes that lived on an ancient seafloor, according to a study in Wednesday#39;s journal Nature.《自然》杂志周三刊登的文章报道,澳大利亚的科学家在格林兰岛一块新融化的区域发现育于古代海床的微生物菌席化石。The discovery shows life may have formed quicker and easier than once thought, about half a billion years after Earth formed. And that may also give hope for life forming elsewhere, such as Mars, said study co-author Martin VanKranendonk of the University of New South Wales and director of the Australian Center for Astrobiology.该报告的联合作者、也是新南威尔士大学学者和澳大利亚地球科学研究中心负责人的马丁·范克朗多克表示,该发现说明地球生命形成的时间要比预想的早而且容易,大概在地球形成5亿年就形成了。该发现也可能实火星等其他星球也许也存在生命。;It gives us an idea how our planet evolved and how life gained a foothold,; VanKranendonk said.范克朗多克说道:;这一发现有助于我们理解地球的演化,以及地球生命是如何育的。;Scientists had thought it would take at least half a billion years for life to form after the molten Earth started to cool a bit, but this shows it could have happened quicker.地球早期火山喷发不断,内部温度很高。科学家们此前一直认为生命体是在地球温度稍微变冷的时候出现的,但是现在如果该发现属实的话则意味生命体开始形成的时间要更早。That#39;s because the newly found fossil is far too complex to have developed soon after the planet#39;s first life forms.因为这些新发现的化石很复杂,不可能在地球上出现生命体不久就形成。In an outcrop of rocks that used to be covered with ice and snow which melted after an exceptionally warm spring, the Australian team found stromatolites, which are intricately layered microscopic layered structures that are often produced by a community of microbes.来自澳大利亚的科学小组无意中在凸起的岩石中发现了叠层石,叠层石是由微生物群构成的沉积结构。这些岩石此前被冰雪覆盖,由于极度暖和的春天,冰雪融化,它们才得以;重见天日;。The stromatolites were about 1 to 4 centimeters high.这些叠层岩介于1-4公分之间。It ;is like the house left behind made by the microbes,; VanKranendonk said.范克朗多克说道:;它就像是微生物们留下的空房子;。The dating seems about right, said Abigail Allwood, a NASA astrobiologist who found the previous oldest fossil, from 3.48 billion years ago, in Australia.美国航空航天局的地质学家阿比盖尔·奥尔伍德对此提出了自己的质疑,她此前曾于澳大利亚发现了34.8亿年前的化石。But Allwood said she is not completely convinced that what VanKranendonk#39;s team found once was alive. She said the evidence wasn#39;t conclusive enough that it was life and not a geologic quirk.但是奥尔伍德还表示,这一时间推论看起来没什么问题,该团队的发现并不能完全说自己。她认为本次发现的据还不足以明他们发现是生命体而非地理学上的巧合。;It would be nice to have more evidence, but in these rocks that#39;s a lot to ask,; Allwood said in an email.奥尔伍德在一封邮件中写到:;能发现更多的据当然很棒,但是目前发现的这些岩石中还存在很多谜团。; /201609/466138贵阳/念珠菌性龟头炎治疗方法 You#39;re feeling full but here#39;s the waiter with the dessert . You#39;re about to say ;No thanks; when your friend orders baked cheesecake. And soon you#39;re saying: ;I#39;ll have one too, thanks.; Studies repeatedly show that what we eat is highly influenced by who we eat with. The most recent research, presented at last week#39;s American Heart Association meeting, found that the chance of a ;diet lapse; was 60% when eating with others. The research followed 150 people trying to lose weight or keep weight off, for a year, using phones and an app to capture what and where they ate. Those in the study were asked to limit their calories. They were most successful in keeping to their diet when they ate alone. Work, with its temptations of cake for somebody#39;s birthday, led to a 40% chance of a diet lapse. The car was the safest place, with only a 30% chance of overeating.你感觉饱了,但务生却站在一旁拿着一份甜点菜单。你准备说;不用了,谢谢;,但你的朋友却点了烤芝士蛋糕。很快你就会说:;给我也来一份吧,谢谢。;研究多次表明:和我们一起用餐的人会影响我们吃什么。上周在美国心脏协会会议上,有人提出最新的一项研究发现:当和别人一起用餐时,;饮食失调;的几率是60%。该研究对150位想要减肥的人进行了为期一年的调查,使用手机或应用程序捕捉他们吃了什么,以及在哪儿吃的。研究人员要求受试者减少卡路里摄入量。当他们一个人吃饭的时候,他们最能控制自己的饮食。工作和某人生日蛋糕的诱惑使得人们;饮食失调;的几率为40%。车是最安全的地方,在车上过度饮食的几率只有30%。But it#39;s annoying that dining with family or friends could make us eat more. A study of 63 adults who kept seven-day dairies found that eating with people increased meal sizes by 44% and participants ate more fat than when they ate alone. The lead researcher, US physiologist John de Castro, suggested that eating alone would reduce caloric intake and improve diets. In another study he showed that meals eaten with spouses and family had more calories and were eaten faster, while those with friends were as large but lasted longer. This was true for all meals of the day, and if men were at the table, women tended to eat more than usual. So although eating with friends or family is one of the joys of life, if you want to watch your weight, should you eat on your own?但是与家人或朋友吃饭会让我吃的更多这一点着实令人烦恼。有一项研究有63位参与者,他们写了7天的日记,研究发现:相比一个人单独就餐,和别人一起吃饭时他们的饭量增加了44%,而且摄入的脂肪量也更多了。该研究的主研究员--美国心理学家约翰·德·卡斯特罗指出:一个人吃饭会减少卡路里摄入量、改善人们的饮食。在另一项研究中,他表明:和妻子/老公、家人一起吃饭,摄入的卡路里量更多,但吃饭的速度更快,而与朋友一起吃饭,饭菜也很丰盛,但吃的时间会更久。一日三餐都是如此,如果饭桌上有男性,女性往往会比平常吃的更多。所以,虽然与朋友或家人吃饭是人生一大乐事,但如果你想控制体重,最好还是一个人吃吧。We seem to be compelled to model how we eat on those around us; not only on what they eat but on how big they are. A study in the journal Appetite showed that in the presence of an actor in a fat suit, people in a restaurant ate 31.6% more pasta, whatever she ordered. If she ordered salad, they served themselves 43.5% less salad.我们似乎被迫去模仿周围人的饮食;不仅模仿他们吃什么,而且还模仿他们饭量。Appetite杂志上刊登的一项研究表明:穿着肥硕西的演员出现在餐厅时,不管她点了什么,餐厅里的人都会多吃31.6%的披萨。如果她点了沙拉,那他们会减少43.5%的沙拉摄入量。译文属 /201703/500529贵阳天伦不孕不育医院收费高吗

贵州省贵阳市天伦医院复通手术大约多少钱Because they are extremely tricky to make and many of their ingredients can be expensive and/or difficult to source.因为它们很难制作,很多原料都很贵或者不易获取。Macaron shells are made by folding almond flour (or some other nut flour) and confectioners sugar into a meringue (sugar and egg whites). Sounds easy enough, but it has to be done just right. The ratio of sugar-to-almond flour-to-egg has to be very precise — you have to weigh your ingredients to the gram; you can#39;t do it by volume. I suppose you could but it could easily mess up your batch.马卡龙的壳是一层杏仁面粉(或其他一些坚果面粉,糖和调和蛋白制成。听起来简单极了,但是要做到恰到好处很不容易。糖、杏仁面粉、鸡蛋的比例都必须非常精确。需要将原料按克称量;另外,你不能按体积来计算。我觉得其实你可以按体积来算,但是这样很可能会搞砸的。Assuming you#39;ve even measured the ingredients properly, you need to fold it correctly. Under-mix and they#39;ll be stiff. Over-mix and they#39;ll be goo. You have to pipe the shells to be uniform in size, rest them so they can lose their peaks and watch them like a hawk for as long as they#39;re in the oven. If anything anywhere in the process goes wrong, the entire batch can be lost. And macarons are as much about looks and style as taste; a cookie that tastes good but is burnt, missing its foot or cracked will not cut it.即使你恰当地称量了材料,你还必须正确地把它们卷起来。不充分混合他们会变硬。过度混合它们又会太软。你必须把这些壳都卷成统一的尺寸,把它们放在一边,让它们变得柔软,从放进烤箱的开始一定要一直看着它们。如果步骤中的任何一处出了差错,整个一批就全部白费了。一个小曲奇味道很好但是烤焦了、少了一个角或者破了是不会有什么影响的。但是马卡龙的外形、样式和口味一样,都很重要;The fillings don#39;t have to be that difficult. I#39;ve used buttercream, ganache and candied fruit, among others. It#39;s the shells that pose the difficulty, and unless you want a plain shell, you#39;ll need to invest in good-quality vanilla, edible flowers, cocoa, flavor compounds, spices and dye. Most of that ain#39;t cheap, and neither is almond flour, unless you buy it in bulk.內馅没有那么难做。我用了奶油乳酪、巧克力酱和果脯等等。其实是壳使得制作难度提升,而且如果你不想让壳平平的,你就需要买很好的香草酱、可食用的花瓣、可可粉、混合调味剂、香辛料和染料。它们大都价格不菲,扁桃仁面粉也是,即使你批发,还是很贵。In summation, the comparatively high cost of macarons is a function of their difficulty to make; the time it takes to make them; and the cost of their ingredients, many of which are highly specialized. Most people are also unwilling or unable to make them at home (they are not cupcakes and there is no boxed mix for them), so they#39;re willing to pay more to get them from a bakery.总的来说,马卡龙的高成本来源于它的制作难度、制作时间和原料价格,这其中的大部分都需要很专业才行。大部分人也不愿意在家制作它们(它们不是杯子蛋糕,也没有混合好、方便制作的原料包),所以人们愿意花更多的钱去面包店买马卡龙。 /201705/507939 贵阳/龟头炎外治遵义医院修复处女膜多少钱
