Lobster Age Shown By Counting Its Rings Like A Tree, Study Reveals
PORTLAND, Maine -- For the first time, scientists have figured out how to
determine the age of a lobster – by counting its rings, like a tree.
Nobody knows how old lobsters can live to be; some people estimate they live
to more than 100.
But knowing – rather than simply guessing – their age and that of other
shellfish could help scientists better u... 阅读全帖

It's about aging. Any comment?
Turns out that the elusive Fountain of Youth may exist after all … in our
heads.
Scientists at the Albert Einstein School of Medicine say they’ve discovered
a brain region that may control aging throughout the entire body. By
manipulating that region, they were able to extend the lives of mice by 20
percent. The finding, detailed in a paper published in Nature on May 1, may
lead to new ways of warding off age-related diseases and increasing life
spans.

来自主题: Biology版 - attitudes about aging
aging现在貌似比较热,但这个领域纷争仍然比较多:
a,aging是否是个programmed precess。很多人认为aging may be affected rather t
han be regulated。也就是说,aging就像机械磨损一样,是个被动的过程,它不是受主
动调控的,不过这个被动的过程可以被干扰。
b,低等生物的aging和高等生物的aging是否共用类似的机制?如果同意aging是个prog
rammed的过程,就不会有第二个问题了。但因为第一个问题有争论,所以也就有了第二
个问题的争论。有人认为人的aging机制和低等生物的并不一样,比如目前在低等生物中
,认为抑制insulin like signaling可以延缓aging,但在人的案例里面,对早衰的一种
治疗办法就是激素治疗,包括IGF-1,这似乎看上去和低等动物中做出来的结果是矛盾的

大家怎么看aging的研究?

Hypothalamic stem cells control ageing speed partly through exosomal miRNAs

logistic regression,
1) if the coefficient of age is positive/ age square is negative, the age
effect is invert U shape.
2) the coefficient of age is negative/age squared is positive, the age
effect is U shape.
But, 如果age和age squared 都是正的或者都是负的呢,age effect是exponential

大家在做economics/statistics model时会Keep都正或者都负的情形吗?理论上make

来自主题: Biology版 - Aging领域有啥牛人?
现在aging领域的问题在于对aging的认识,actually aging is regulated rather
than controlled。这也是现在很多pathway做到下游就没法再按传统通路A--B--C的方
式做下去的原因。DR,我同意你的看法,算是一个影响因素,但不是什么多激动人心的
东西。reproductive system非常非常有意思,不过不抱什么期望怎么帮助aging研究摆
脱困境。这涉及到进化的问题了,到底aging是不是受进化选择。
有些人依旧按照传统pathway的方法往死了做,包括gary和canthia目前都有一部分工作
属于这类,其实意义已经不大了,这俩的徒弟,大部分都如此,可想而知就更惨了。
所以,我觉得andy很聪明,其实个人认为他最重要的发现不是他那些好看的cns通路文
章, 而是他几年前的science以及最近的cell的工作,涉及怎么将insulin 通路和
aging相关的疾病联系到一起,其实这些工作反应的是对aging的认识,自然也会影响到
genetic pathway在其中到底起什么作用:aging不是一个development

可能是为了给对《高达AGE》初期机体设定失望的人吃一颗定心丸,今天万代泄露了高
达AGE-1的后继机体AGE-2和AGE-3的设定图。从设定上来看,的确和机械设定师海老川
兼武所说,有一代一代变得越来越先进的感觉,但是两台后继机的的造型似乎“似曾相
识”,AGE-2是与Z高达同样定位变形MS,但是外形和高达OO极其相似,而AGE-3则几乎
是全装甲高达ZZ的翻版。《高达AGE》看来是想靠后继机来找回高达的风格,但是这种

The onset of wrinkles, muscle wasting and cataracts has been delayed and

It was done by "flushing out" retired cells that had stopped dividing. They
accumulate naturally with age.
The scientists believe their findings could eventually "really have an
impact" in the care of the elderly.
Experts said the results were "fascinating", but should be taken with a bit
of caution.

美国租车25岁以下也不用交young age fee?!不是在开玩笑!网友贲腾有自己的诀窍。

几条说明:


1.此方法只适用于hertz avis enterprise和budget 其他公司的没研究
2.如果你到了25岁,也看看吧,每次可以省差不多20%左右,算ok的deal吧作为一个不到25
岁的同学 我表示每次租车每天30块钱左右的young age fee实在是太蛋疼了,以前的办
法一直是找个25岁以上的哥们儿帮忙租车。劣势是一旦出了事故,就玩儿丢了。因为签

I think that it is very interesting. I ever thought the similar questions
. Cai Lab is very strong on the inflammation/hypothalamus function/NF-kB/
Diabetes and ageing. Actually we don't know clearly if there are "trigger or
switch" in our body to control or execute system ageing.This paper
partially answer the question.
Also, many environmental factors influence ageing. Ageing is systemic "
phenotype", maybe, different tissues have different mechanisms to regulate
ageing.

我要建一个logistic model, Y=death(0,1). predictors 有 gender, age。。
请问age应该分段吗,比如:18-27,28-37,38-47。。。
我试了一下,结果如下:

1.18-27 0.214
2.28-37 0.356
3.38-47 0.556
4.48-57 0.631
5. ....
如果不分段,age 的 odds ratio=1.047,
如果在SAS code里面加上 unit=10, age 的 odds ratio =1.584
所以,请问age 这里应不应该分段啊,万分感激!!!
