Skin cells quickly cover the wound and form what is called a blastema. 当蝾螈的腿被切断后,它体内的血管会迅速收缩并止血,皮肤细胞迅速地覆盖在伤口上,形成所谓的胚基。 yeeyan One such question, that of how damaged tissues regenerate, is being studied in salamanders by Elly Tanaka and a team of colleagues at the Max Planck Institute in Dresden. 这样一个问题,即受损组织如何自愈的问题,现在是艾丽•田中与其组员所在的,位于德累斯顿的“马克思普朗克研究所”目前的课题。 ecocn Viewing the salamanders under a fluorescent microscope, the researchers were able to see the algal pigments“ shine” when they were illuminated with light of a certain wavelength. 采用荧光显微镜对火蜥蜴进行观察,研究人员能够看到海藻色素“发光”当它们被一定波长的光照射的时候。 yeeyan What do frozen salamanders, vampire deer, and endangered leopards have in common? 冰冻的蝾螈、吸血鬼鹿以及濒临绝种的豹有何共同之处? breezecn Amphibians frogs, toads and salamanders, for example, were not“ completely evaluated” with more than90% of species assessed until2004. 举例来说,直到2004年,双栖动物青蛙、蟾蜍、蝾螈并未受到“完全评估”只有90%多一些的种类受到评估。 ecocn Amputees could regenerate limbs and organs thanks to scientists who have come close to discovering how salamanders grow back lost legs and damaged organs. 科学家们即将发现蝾螈是如何将残缺四肢和受损器官再生的秘密了,被截肢的残疾人将会得益于此,重新长出四肢和身体器官。 yeeyan Aristotle even confused salamanders with snakes, attributing to the latter the power of growing new eyes. 亚里士多德甚至把蝾螈同蛇混为一谈,认为蛇具有长出新眼睛的能力。 yeeyan By tracking individual cells in genetically modified salamanders, researchers have found an unexpected explanation for their seemingly magical ability to regrow lost limbs. 通过跟踪研究经过基因改造的蝾螈的单个细胞,对于它们失去的肢体再生这种貌似神奇的能力,研究人员找到了一个出乎意料的解释。 yeeyan Elephants show empathy, and even salamanders and spiders show a range of personalities. 大象表现出共鸣,即使蝾螈和蜘蛛,也都展现出自己一定程度上的个性。 yeeyan Even more strangely, the researchers think the salamanders might inherit the alga from their parents. 更奇怪的是,研究人员认为这些海藻是火蜥蜴从它们父母那里继承来的。 yeeyan If Tanaka’s right that blastema cells don’t become pluripotent, then the findings raise another possibility— not just for salamanders, but for people. 塔纳卡认为芽基细胞没有变得具有多能性,如果她是正确的话,那么,这一发现又增加了另一种可能性-不仅对于蝾螈,而且对于人类。 yeeyan It’s also possible that the axolotl’s mechanisms are different from other salamanders. 也可能美西螈的机理不同于其他种类的蝾螈。 yeeyan Just because bees, salamanders, fish and humans share similarities in their ability to detect number, it does not necessarily mean they all inherited the talent from a common ancestor. 如果单纯因为蜜蜂、蜥蜴、鱼和人类都具有相似的识数本能,就认为这些生物的识数能力都是从同一个祖先那里演化而来的,也未必。 yeeyan Rather than having their cellular clocks fully reset and reverting to an embryonic state, cells in the salamanders’ stumps became slightly less mature versions of the cells they’d been before. 蝾螈残肢细胞并不使细胞钟完全重置然后回到胚胎状态,而是变成了比原来略微不成熟的细胞变体。 yeeyan Scientists are getting closer to understanding the subtle genetic and physiological processes that allow salamanders to regenerate their limbs from scratch. 科学家们正逐渐理解蜥蜴重新长出四肢的精细的基因和生理过程。 yeeyan Sharks, turtles and salamanders from the bird's time period have also been found in the region. 在此地区还发现了与这种鸟同时期的鲨鱼,海龟和蝾螈。 yeeyan So do salamanders. 蝾螈也是如此。 ecocn So it seems that for the salamanders to discriminate between two big numbers, the largest must be at least twice as big as the smallest see image. 所以要想让蝾螈辨别两个较大的数,似乎较大的那个应该至少是较小那个的两倍。 yeeyan Spotted salamanders lay their eggs in pools in spring. And the egg capsules actually look green, thanks to the algae that surrounds the resident embryos. 斑点蝾螈春天在池塘产卵,卵的表面是绿色的,因为藻类围绕着在那里安家落户的胚胎。 hjenglish Spotted salamanders lay their eggs in pools in spring. 斑点蝾螈在春天将他们的蛋生在水池中。 yeeyan The latter gave rise to land vertebrates, some of which, such as the Mexican axolotl salamanders, retained electrosense ability. 后者是陆地脊柱动物的祖先,他们当中的一些还保持着探测电磁场的能力。 cri |
