1、When people enter into life sciences field, he will find, everything is so exciting and glamorous, so cant help being attracted to step by step to deeply explore the mystery of life. For the life of research in improving the human condition has a significant role, such as the poem said life seventy
2、ancient rare, now is life eighty dont, for instance the grain yield per mu in recent ten years doubled, many pessimistic scholars that human famine did not appear.In August, Samsung and your passion Olympic medal winners in front of and behind the scenesLG mobile phone one yuan take a wonderful mobi
3、le phone game RaidersLife science is systematically expounded and life characteristics relevant to the major subject of science. Dominating the inanimate world of the physical and chemical laws also applies to the life world, without giving the living substance a mysterious vitality. For in-depth un
4、derstanding of the life sciences, physics, chemistry, it can also promote human other areas of knowledge development. For example, in the life science century problem is intellectual Erlai from where? Our single neuron activity well, but tens of billions of neurons in brain after combined into how t
5、o generate intelligence but know nothing at all. It can be said that the human mind s biggest challenge is how to explain intelligence itself. On this one problem gradually break will also change accordingly human knowledge structure.Life science research not only depends on the physical, chemical k
6、nowledge, but also on the latter provide equipment, such as optical and electron microscopy, protein electrophoresis, ultracentrifuge, X - ray spectrometer, NMR spectrometer, positron emission tomography and so on, too numerous to mention. Life science is also from various disciplines gathered from.
7、 The intersection between different disciplines caused a lot of the prospect of unlimited growth point and new subject.Life science research or is under study is the main topic: biological material chemical essence of what? These chemical substances in the body is how to translate and exhibit featur
8、es of life? The composition and structure of biological macromolecules is how? How cells work? Of every hue cells to complete various functions? Gene as a genetic material is how to play? What mechanisms induce cell replication? A fertilized egg cell to develop into many different cell types is comp
9、osed of highly differentiated multicellular organisms singular process using the genetic information? A variety of cell types is how to combine to form the organs and tissues? The species is formed? What factors cause evolution? Humans are still evolving? In a specific ecological niche in the relati
10、onship among the species? What factors govern the habitat of each species number? Animal behavior physiology is based on what? Memory is formed? The memory in what place? The factors which can influence learning and memory? Intelligence by he Erlai? In addition to the earth, space and other intellig
11、ent beings? How did life begin? Wait.In the study of accumulated knowledge have been or are being applied to human society, and the enormous benefits such as reduced human disease and animal and plant diseases, improving human nutrition, reduce environmental pollution, the protection of natural reso
12、urces and so on.In recent years, biological engineering, therefore we are facing great opportunities and challenges. At this critical time, we must dosomethinpreviouslyunreleased, understand and participate in decision making.当人们真正进入到生命科学的范围之后，他会发现，一切是那样地令人激动和富有魅力，从而不由自主地被吸引着一步一步地去深入地探索生命的奥秘。对于生命的研究
13、在改善人类的状态方面有着显著的作用，比如古诗说“人生七十古来稀”，如今是“人生八十不稀奇”，又比如粮食亩产量近十余年里成倍增长，许多悲观学者所预言的“人类大饥荒”并没有出现。 8月,三星与您激情奥运 奖牌获得者的台前幕后 LG 手机一元抢拍 精彩手机赛事全攻略 生命科学是系统地阐述与生命特性有关的重大课题的科学。支配着无生命世界的物理和化学定律同样也适用于生命世界，无须赋于生活物质一种神秘的活力。对于生命科学的深入了解，无疑也能促进物理、化学等人类其它知识领域的发展。比如生命科学中一个世纪性的难题是“智力从何而来？”我们对单一神经元的活动了如指掌，但对数以百亿计的神经元组合成大脑后如何产生出智
14、力却一无所知。可以说对人类智力的最大挑战就是如何解释智力本身。对这一问题的逐步深入破解也将会相应地改变人类的知识结构。生命科学研究不但依赖物理、化学知识，也依靠后者提供的仪器，如光学和电子显微镜、蛋白质电泳仪、超速离心机、X-射线仪、核磁共振分光计、正电子发射断层扫描仪等等，举不胜举。生命科学学家也是由各个学科汇聚而来。学科间的交叉渗透造成了许多前景无限的生长点与新兴学科。生命科学研究或正在研究着的主要课题是：生物物质的化学本质是什么？这些化学物质在体内是如何相到转化并表现出生命特征的？生物大分子的组成和结构是怎样的？细胞是怎样工作的？形形色色的细胞怎样完成多种多样的功能？基因作为遗传物质是怎
15、样起作用的？什么机制促使细胞复制？一个受精卵细胞怎样在发育成由许多极其不同类型的细胞构成的高度分化的多细胞生物的奇异过程中使用其遗传信息？多种类型细胞是怎样结合起来形成器官和组织？物种是怎样形成的？什么因素引起进化？人类现在仍在进化吗？在一特定的生态小生境中物种之间的关系怎样？何种因素支配着此一生境中每一物种的数量？动物行为的生理学基础是什么？记忆是怎样形成的？记忆存贮在什么地方？哪些因素能够影响学习和记忆？智力由何而来？除了在地球上，宇宙空间还有其它有智慧的生物吗？生命是怎样起源的？等等。在上述问题的研究中积累起来的知识已经或正在应用于人类社会，并产生了巨大的效益如减少人类疾病和动植物病害、
16、改善人类的营养状况，减少环境公害、保护自然资源等等。近年来，生物工程的兴起，使我们面临着重大的机遇与挑战。在这一关键时刻，我们必须有所作为，理解并参与做出决定。为什么他们获得了2011诺贝尔医学/生理奖？摘要： 随着10月份的到来，各项诺贝尔奖项也尘埃落定（除了经济学奖），今年的诺贝尔生理/医学奖授予了三位免疫学家ules A. Hoffmann、Bruce A. Beutler和Ralph M. Steinman，免疫学领域的研究人员也许对于这三位科学家的成果贡献很熟悉，但是作为非免疫学领域，或者说非生物学领域的读者来说，其它领域也许有更为引人瞩目的成果，为何他们能获得今年的诺贝尔生理/医学奖呢？ 生物通报道：随着10月份的到来，各项诺贝尔奖项也尘埃落定（除了经济学奖），今年的诺贝尔生理/医学奖授予了三位免疫学家ules A.
