东莞市莞城医院激光除皱多少钱广东东莞市鼻翼整形多少钱Woo…Its freezing out.哇,外面太冷了。Come on, Its not that cold.不会吧,没那么夸张。Sure it is. Yael.I guess theres just no way I can go jogging today.确实很冷啊。我想今天也没办法跑步了。Oh, so thats what this all about.原来你是不想锻炼。Not really. What if my lungs freeze?也不完全是。如果我的肺结冰了怎么办?Actually, your body is designed so that by the time air reaches your lungs, its been warmed upand moisturized by your nasal passages, throat, and trachea.实际上,我们的身体是有应对措施的。当空气进入肺部之前就已经被鼻腔,喉咙和气管加湿,加热。Besides, the blood supply in yourlungs is so well developed that theres virtually no way they can freeze-the circulating blood keepsthem nice and toasty.另外,肺部里的血液供给很充足,几乎没有可能结冰-—血液循环让肺部保持正常和舒适。Oh,yeah. So why does it hurt to breathe this really cold?是吗?那为什么在呼吸冷空气时会疼痛?Well,when the air is frigid, it doesnt warm up sufficiently before it reaches the airways leading toyour lungs, and so it shocks the surrounding muscles and causes them to contract.因为在寒冷的空气到达通向肺部的气管时还没有得到充分的热身,所以冲击到周围的肌肉使其收缩。This, in turn,causes your bronchial tubes to contract too, which results in that tight, prickly feeling.转而使得气管收缩,因此你就会有紧绷刺痛的感觉。Uh,sounds dangerous especially when you exercise in breathe to your mouth. What if mytongue freezes?听起来很危险,特别是用嘴呼吸时,如果我的舌头结冰的怎么办?Well,Don.Unless you suffer from asthma, breathing in cold air wont hurt you-and youd have to worry about frost bite to your fingers and toes long before worrying about your tongue freezing.吸入的冷空气不会对你造成伤害,除非你患有哮喘。你应该担心手指和脚趾的冻疮而不是舌头结冰。201406/306689东莞什么整型医院出名 横沥常平虎门镇全身脱毛手术多少钱

东莞市第六人民医院祛疤手术多少钱You may have heard of supertasters.你可能也听过有这样一个群体—品尝师。These are people who, it was discovered, are carrying around extra taste buds on theirtongues, making the world of eating much more intense.他们是被挖掘出的特殊人群,他们的舌周围广泛分布着味蕾,让吃东西变得异常有感觉。Its not at all an unusual thing: the latest data suggest that oneout of every four people is a supertaster.这并不稀奇:最新数据显示每四个人中就有一个人是品尝师。For them, eating is amuch richer, more flavorful experience than for the rest of us.相比于我们这些普通人,他们吃东西时会有更丰富、更美味的体验。Still, before you get too jealous if youre not a supertaster, it turns out there are drawbacks tohaving a technicolor tongue.然而,你也不用因为自己无法成为超级品尝师而对他们羡慕不已。A study that looks specifically at supertasters over the age of sixty-five found that they have more colon polyps than folks who arent so taste bud gifted.事实明,拥有那样华丽的舌头也会带来某些不好的影响。专门对65岁以上的品尝师展开的一项调查研究发现,他们比那些未被赋予超常味蕾的人们患结肠息肉的概率更高。Colon polyps are the things you want to have removed before they become cancerous, which iswhy all folks fifty and older should get a yearly colon exam.结肠息肉容易发生癌变,因而它是人人得而诛之,这也是为什么人们上了50岁每年都得进行一次肠息肉检查。Why do supertasters have more colon polyps?为什么品尝师们容易患上结肠息肉?It isnt known.具体原因还待考。But supertasters also weigh more onaverage than non-supertasters, and weight increases cancer risk.但有一点,品尝师们的体重一般都比普通人重,而体重会增加患癌症的风险。The reason for this may be assimple as it sounds: eating is more fun when you taste in 3-D.而他们体重偏重的原因就跟大家听起来一样:多方位的品尝食品时,饮食让人倍感无穷乐趣。Some researchers think, however, that the problem may not just be an increase in pleasure.然而,很多研究人员又认为原因很可能不仅仅是在饮食当中增加了乐趣。Those extra taste buds may also drive people away from food thats good for them, such as vegetables,because the taste of, say, a brussels sprout is just too intense.这些多出来的味蕾会让品尝师们对一些有益身体健康的食物敬而远之。这是因为这些食物的滋味,比如说抱子甘蓝,就太重了。 201405/297923东莞市樟木头医院隆鼻多少钱 Are aliens going to eat us?外星人会来吃我们吗?Thats more of a science fiction question.这更像是科幻小说里的才会出现的问题。But science does havesomething to say here, and sometimes purely imaginativequestions are great tools for helping us think about how the realworld works.但是在这个问题上我们还是可以寻求科学的。很多时候像这种纯粹异想天开的问题却能够帮助我们更好地思考,更好地认识这个世界。First, its not strictly impossible.首先,严格地说,这也不无可能。Many scientists agree that theMilky Way galaxy is probably brimming with living things.许多科学家都认为系里可能到处都是生物,That doesnt mean any of them aresmart enough to build interstellar spaceships, but lets assume they are.但这并不是说它们就有能力建造星际间飞船。退一万步说,就算它们有这个能力来建造星际间飞船,Still, why are theyunlikely to eat us?可是,它们又为什么要吃我们呢?One reason lies in energy itself.原因之一就在于能量本身。The point of eating is to take in usable energy.吃东西最主要就是为了摄入可用的能量。A lion will expend a lot of energy running down azebra because, once it is caught, the calories contained in the meal far outweigh those expended in the chase.一头狮子可以耗掉大量的体力去追捕一匹斑马,那是因为一旦抓住了那匹斑马,它能摄入的斑马肉里的能量大大超过了他在追捕过程中消耗的能量。If this werent true–say, if the zebras body only had the caloric contentof a grape–then the energy expended would outweigh the energy gained, and the lion wouldlose out.如果以上都不成立,假如斑马肉里所含能量很少—少到根本就无法补充狮子追捕所耗能量,那么这头狮子也只能是白白耗掉体力了。Any alien predators would face the same problem.既然有这样的说法,那么食肉的外星人也会面对同样的问题。The amount of energy expended in building aspace program, fueling rockets, to say nothing of getting from one star to another, would behuge.建造一个空间计划,制造燃料火箭都需要消耗很多能量。更不用说从一个星球飞至另一个星球需要消耗更多的能量!For any realistic technology it would far outweigh the benefit of just munching on people.It would be like climbing Mount Everest in order to pick a few berries.与其猎食人类,还不如将那些能量用于更有实际意义的科技开发。其实猎食人类就像是辛辛苦苦攀上珠穆朗玛却只为摘些果子一样大材小用,劳民伤财。Some day we ourselves may travel to other planets. But any species that goes to such lengthsmerely to find food will find itself quickly exhausted.也许某一天人类能够踏上其他星球的土地。但是,任何一个为寻觅食物而踏上其他星球的物种终将认识到如此行径只会消耗掉自己的能量——自取灭亡。 /201408/318062东莞妇幼保健院打溶脂针多少钱

东莞横沥常平虎门镇脸部抽脂价格YAEL:Today, on a Moment of Science, were conducting an experiment on sleep deprivation.雅艾尔:在今天的科学一刻节目中,我们正在进行的是一项睡剥夺眠的实验。On my right, we have my friend Bob, who hasnt slept in eighty-eight hours straight!我的右手边是88小时没有合过眼,我的朋友鲍勃。Bob? Bob? Okay, so hes pretty unresponsive.鲍勃?鲍勃?好吧,他没什么反应。And on my left, we have Don, who has been restricted to no more than four hours of sleep a night for the past two weeks.而我的左边是唐,他被限制在过去两周每晚睡眠时间不超过4个小时。How are you feeling, Don?现在感觉如何,唐?DON:Well, Im a little tired, Yael, but not as tired as Bob over there, who I think is drooling.唐:嗯,雅艾尔,我只是感觉有点累,但是没有鲍勃看起来那样累,我觉得他在流口水。YAEL:If youve ever relied on a doctor or an airplane pilot, then you know theres a lot at stake over whether Don is telling the truth about how tired he feels.雅艾尔:如果你的吃饭职业是医生或飞机飞行员,那你就会清楚唐在讲自己是否有多累的感觉存在着很多危险。DON:Of course Im telling the truth. I feel fine.唐:我当然说的是实话。我感觉很好。YAEL:Well, you might think you feel fine, but I have in front of me the result of the cognitive performance tests both you and Bob over here took earlier today.雅艾尔:嗯,你可能会自认为感觉很好,但在我面前的是今天早些时候你和鲍勃两人的认知表现测试结果。And guess what?! Don! Don!你猜结果如何?唐!唐!DON:Huh? What?唐:嗯?什么?YAEL:These cognitive performance tests show that you and Bob are having equal trouble performing some pretty basic tasks.雅艾尔:这些认知表现测试显示你和鲍勃在执行一些非常基本的任务时有着一样的麻烦。DON:But Bob hasnt slept in three days!唐:但鲍勃可是3天没睡过觉!YAEL:Exactly. So that means that even missing only a couple of hours of sleep a night really adds up if you do it every night.雅艾尔:没错。所以即使如果每天只是少几个小时的睡眠,长此以往如此也会有显著的效果。In other words, sleep debt is cumulative,换句话说,睡眠债是累积的,and right now, you have no more business going out there and driving a car than Bob does.而现在,比起鲍勃,你最好也别出门谈生意及驾驶车辆。Whats more, youre so tired right now that you cant even properly evaluate how tired you are, which makes your sleep debt even more dangerous.更重要的是, 现在如此疲倦的你甚至不能正确地评价自己有多疲倦,这使得你的睡眠债更危险。DON:Guess I better catch up on some Zs!唐:我想自己最好感觉补点觉!YAEL:Looks like Bobs beaten you to it. 雅艾尔:看起来鲍勃已经先你一步。 201311/263599 麻涌中堂望牛墩洪梅镇治疗痘痘多少钱东莞医学整形美容切眼袋手术多少钱
