17．As we know，DNA testing is very useful for crime fighting．But now crime fighters could have a new tool at hand．Researchers have developed a cutting-edge （前沿的） technique to identify human hair．Their test is quicker than DNA analysis techniques currently used by the police．
DNA testing is commonly used for identification because DNA is unique to each individual．However，environmental and chemical processes can degrade（降解） DNA，limiting its usefulness over time．Protein （蛋白质） in hair，on the other hand，is more stable than DNA but can also have variations （变异体） that may be unique to the individual．
"Our analysis process can be used universally，"says Ms．Huang，"One of our samples even included dyed hair and the test was 100 percent accurate．The test was able to distinguish East Asians，Caucasians and South Asians．"
Dr．Beauchemin says she has got in touch with law enforcement agencies about using the new technology．She is also planning to collect more hair samples and continue her research with a goal of finding where exactly in the world hair sample is from，to look for more races and determine specific age．
"We are in a very similar place with protein-based identification to where DNA testing was during the early days of development，"said chemist Brad Hart．"This method will be a game-changer，and while we've made a lot of progress toward improving it，there are steps to go before this new technique is able to reach its full potential．"

There is nothing wrong with that，except the fact that on some people a bright red sweater is extremely unbecoming．The situation can even become dangerous，if the top crowd decides that it is smart to drink or to drive cars at seventy miles an hour（37）Ethey are like the sheep being led to the butcher．（38）Gchances are that one time or another you probably did something you knew to be wrong．You may have excused yourself by saying，"Gee，the crowd does it．"Well，let the crowd do it，but don't do it yourself．（39）A．

11．The current Ebola （埃博拉病毒）outbreak in western and central Africa has infected at least 3，069 people，including 1，552 dead，making it the largest outbreak in history．Ebola is a deadly virus-about 60 percent of people infected with it have died．
How is Ebola doing its harm？
When a person becomes infected with Ebola，the virus damages the body's immune （免疫的）cells，which defend against infection，said a researcher at Lancaster University．But if a person's immune system can stand up to this attack，then he is more likely to survive the disease．
The patients that survive it best are those who don't get such a bad disadvantage in immune system．But if the body isn't able to get rid of this attack，then the immune system becomes less able to regulate（调节） itself．This means the immune system is more likely to run out of control，leading to a drop in blood pressure，multi-organ failure and eventually death．
What are the common symptoms of the disease？
Fever．Headache．Joint and muscle aches．Weakness．Diarrhea．Vomiting．Stomach pain．Lack of appetite．Chills．Rash．Redness in the eyes．Hiccups．Cough．Sore throat．Chest pain．Difficult breathing or swallowing．Bleeding inside and outside of the body．
How to prevent the spread of Ebola？
Ebola can be spread primarily via direct contact with patients，specifically the blood and fluids of an infected patient．
We should avoid contact with infected patients and objects such as clothing，bedding，and needles used by them．Avoid areas where infections have been reported．For now，the disease has only been confirmed in central and West Africa，four cases in America and Europe．Avoid eating wild-caught bush meat．Researchers have suspected that the disease came to humans via animals，probably through the meat of primates（灵长类）．If you're in an area where the disease has been reported，avoid purchasing，eating，or handling wild game to stay on the safe side．
Wear protective medical clothing if you're around infected patients．Extreme caution is necessary．Hospital workers must use masks，gloves，goggles，and gowns，which needed to be worn at all times if you're around infected patients．
How Do People Survive Ebola？
Doctors don't know for certain who will survive Ebola，and there is no specific treatment or cure for the disease．Although in the minority，some people do recover from infection．
Our suggestions include：
Maintain your electrolytes（电解质） and body liquid．Sports drinks can be used．Monitor your blood pressure and control it if necessary．Dropping blood pressure may be a serious sign of infection．Breathe in an oxygen-rich environment．Quickly address any symptoms of infection．Be honest about when and where you're feeling pain．
