读读源代码就好了~~运行不能~~~~这都是因为实验室的电脑对中文一窍不通的缘故~~~~而我自己的电脑搭载的只有程序界面~~~~

那个......我得回实验室上班，明天再说吧......
逃走的老头子，被追杀
-------------------------------------
TODAY
早上九点以前赶到实验室，拿样本，教授老头子说8组两个样本(看来午饭是肯定没有了~~我未来一个月的休息时间也消失了~~果然是黑色的星期一)
忙到十点，对照用的MODEL总算处理完成，回实验室A取药品装瓶~~(就是放在GCMS专用的瓶子里，倒是很好玩，我特别喜欢这个瓶子^^)
等送到分析室都快11点了，肚子开始饿~~但是艰苦才刚刚开始。
分析实验室很狭窄，我们都坐在玻璃后面(参见电影HULK中的场景)，因为教授想坐着所以我就只好站着(椅子资源不足而且土地资源缺乏严重)。这样站着等结果数据等到快一点，直到教授说午餐时间为止。
令人不快的是MODEL的四个瓶中只有A是OK，其他三个都是F，这样等于还得再来一次~~~~~~~~
大BOSS先生说什么呢？
大BOSS先生说没关系我们周三不是有空可以再来一次嘛......(晕倒.....)
由于将很长时间没有午饭吃，所以增肥计划完全停止中~~
挂在实验室处理幸存数据的老头子，GA的续文很遥远

Cancer test stretches limits /Roxanne Khamsi
A device that detects cancerous cells by measuring their stretchiness has been developed by researchers in Germany. The highly sensitive device, which is the size of a shoebox, uses a laser to take its measurements.
Traditional methods of testing for cancer require 10,000-100,000 abnormal cells in order to work. But the new technique can provide an answer with as few as 50 tumour cells, so that much smaller samples would need to be taken from patients.
So far, testing of the new technology has focused on diluted cell mixtures in the lab, but its creators hope to see its eventual use in hospitals. "We really have a clinical application in mind," says Josef Käs of the University of Leipzig, Germany, who helped to build the device.
The laser test relies on the fact that healthy cells contain an inner scaffolding called the cytoskeleton that helps to hold their contents in place. When cells become cancerous, the cytoskeleton recedes and they become more elastic as a result.
Momentous light
When a laser beam from the device enters a cell, the light gains momentum because of the different conditions inside. According to the law of conservation of momentum, the cell must lose an equal but opposite amount, so its membrane bends towards the light source. "The cell gets a kick backwards," explains Käs. When the laser light leaves the cell, it loses momentum and drags the cell's opposite edge along with it. By applying a continuous beam, the cell gets stretched to its limit.
Without a strong cytoskeleton, cancerous cells are 40% easier to extend than their healthy counterparts. And cells from 'metastasized' tumours — those that have spread through the body — are an additional 30% more stretchy than early-stage cancer cells. This means that the laser could potentially assess how far the disease has advanced. "The softest ones are the most aggressive," says Käs.
Currently, doctors cannot diagnose metastasis without discovering the location of the secondary tumours. The new laser-based method would pick up on metastasis based on cell elasticity alone, he says. In breast cancer, for example, the researchers believe this would mean fewer mastectomies carried out unnecessarily on the basis of guesswork about how far the disease has spread.
Sensitive issue
The test should be much more sensitive than cancer tests that simply use molecular markers to tag renegade cells. Käs explains that when cancer-causing genes begin to act in a cell they produce a small change in its structural proteins, but this has an exponential impact on elasticity. The underlying changes in the cell's DNA, which are the focus of current cancer-detection methods, are nowhere near as dramatic.
Given a sample that contains at least 50 tumour cells, the laser can spot cancer more than 90% of the time, its creators claim. Nevertheless, further studies are needed to determine whether it can spot all types of cancer. "That will take years of testing," says Käs, who presented the findings at a meeting of the Institute of Physics in Warwick, UK, this week.
Talk that such a machine could replace a microscope for cancer screening is "rather premature", says Peter Sasieni, a spokesman for London-based charity Cancer Research UK. He adds, however, that the "highly innovative" device could have future clinical applications.

代表变异猫科上来闪一下……（喂）回复: 【小哀科学院】[禁水]Science Fans进来乱弹(04.10·祝猫生日快乐·生日礼物DN
我想问一下那个学大脑科学的，你能告诉我：大脑在思考简单问题和复杂问题时消耗的能量是否一样多吗？好像是在召唤老头子……？
大脑耗能除了和复杂性有关，显然也不能忽略问题规模这个因素吧。或者将复杂问题等同视为简单问题的叠加？那么耗能应该也是增加的……
PS: 变异猫科？可以……贴图来看看吗……
