New Attempts to Eradicate AIDS Virus

     high-profile¹ attempt to eradicate the AIDS virus in a few patients continues to show promise.
　　But researchers won"t know for a year or more whether it will work, scientist David Ho told journalists here Wednesday for the Fourth Conference in Viruses and Infections.
　　“This is a study that"s in progress²，” says Ho, head of the Aaron Diamond AIDS Research Center, New York.
　　The study involves 20 people who started combinations of anti-HIV drugs very early in the course of³the disease, within 90 days of their infections. They"ve been treated for up to 18 months. Four others have dropped out because of side effects or problems complying with the exacting drug system.⁴
　　The drugs have knocked the AIDS virus down to undetectable levels in the blood of all remaining patients.⁵ And, in the latest development⁶, scientists have now tested lymph nodes and semen from a few patients and found no virus reproducing there, Ho says. “ Bear in mind that⁷ undetectable does not equal absent,"Ho says.
　　Ho has calculated that the drugs should be able to wipe out remaining viruses 一 at least from known reservoirs throughout the body 一 in two to three years. But the only way to prove eradication wouli be to stop the drugs and see if the virus comes back⁸. On Wednesday, Ho said he wouldn"t ask any patient to consider that step before 2 years of treatment.
　　And he emphasized that he. is not urging widespread adoption of such early, aggressive treatment outside of trials⁹. No one knows the long-term risks.
　　But other scientists are looking at similar experiments. A federally funded study¹⁰ will put 300 patients on triple-drug treatments¹¹ and then see if some responding well after six months can continue to suppress the virus on just one or two drugs ’ says researcher Douglas Richman of the University of California, San Diego. Some patients in that study also may be offered the chance to stop therapy after 18 months or more, he says.

Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (BCI) technology could help people with disabilities send commands to machines.
Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic school in Lausanne, Switzerland, demonstrated (展示) a small robotic wheelchair directed by a person’ s thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right band. He could even talk as he watched the vehicle and guided it with his thoughts.
"Our brain has billions of nerve ceils. These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles," Tavella says. "Our system allows disabled people to communicate with external world and also to control devices."
The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.
Prof. Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. "The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair."
He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.

A:make profits from them B:prove the technology useful to them C:make them live longer D:learn about their physical condition

Science and Truth
"FINAGLE" is not a word that most people associate with science. One reason is that the image of the scientist is of one who always collects data in an impartial (51) for truth. In any debate - over intelligence, schooling, energy-the (51) "science says" usually disarms opposition.
But scientists have long acknowledged the existence of a "finagle factor"—a tendency by many scientists to give a helpful change to the data to (53) desired results. The latest of the finagle factor in action comes from Stephen Jay Gould, a Harvard biologist, (54) has examined the important 19th century work of Dr. Samuel George Morton. Morton was famous in his time (55) analysing the brain size of the skulls as a measure of intelligence. He concluded that whites had the (56) brains, that the brains of Indians and Blacks were smaller, and therefore, that whites constitute a superior race.
Gould went back to Morton’s original data and concluded that the (57) were an example of the finagle at work. He found that Morton’s "discovery" was made by leaving out embarrassing data, using incorrect procedures, making simple arithmetical (58) (always in his favour) and changing his criteria-again, always in favour of his argument. Morton has been thoroughly discredited by now and scientists do not believe that brain size reflects (59) .
But Gould went on to say Morton’s story is only an example of a common problem in (60) work. Some of the leading figures in science are believed to have (61) the finagle factor. Gould says that Isaac Newton fudged out to support at least three central statements that he could not prove. And so (62) Claudius Ptolemy, the Greek astronomer, whose master work, Almagest, summed up the case for a solar system that had the earth as its centre. Recent studies indicate that Ptolemy (63) faked some key data or resorted heavily to the finagle factor.
All this is (64) because the finagle factor is still at work. For example, in the artificial sweetener controversy, for example, it is said that all the studies sponsored by the sugar industry find that the artificial sweetener is unsafe, while all the studies sponsored by the diet food industry find nothing (65) with it.
