Today, his discovery of light-emitting diodes, or LEDs, are use

8、d in everything from DVDs to alarm clocks to airports. Dozens of his students have continued his work, developing lighting used in traffic lights and other everyday technology. On April 23, 2004, Holonyak received the $ 500,000 Lemelson-MIT Prize at a ceremony in Washington. This marks the 10th year

9、 that the Lemelson-MIT Program at the Massachusetts Institute of Technology (MIT) has given the award to prominent inventors. “Anytime you get an award, big or little, its always a surprise. “ Holonyak said. Holonyak, 75, was a student of John Bardeen, an inventor of the transistor, in the early 195

10、0s. After graduate school, Holonyak worked at Bell Labs. He later went to General Electric, where he invented a switch now widely used in house dimmer switches. Later, Holonyak started looking into how semiconductors could be used to generate light. But while his colleagues were looking at how to ge

11、nerate invisible light, he wanted to generate visible light. The LEDs he invented in 1962 now last about 10 times longer than incandescent bulbs, and are more environmentally friendly and cost effective. Holonyak, now a professor of electrical and computer engineering and physics at the University o

12、f Illinois, said he suspected that LEDs would become as commonplace as they are today, but didnt realize how many uses they would have. “You dont know in the beginning. You think youre doing something important, you think its worth doing, but you really cant tell what the big payoff is going to be,

13、and when, and how. You just dont know. “ he said. The Lemelson-MIT Program also recognized Edith Flanigen, 75, with the $100,000 Lemelson-MIT Lifetime Achievement Award for her work on a new generation of “molecular sieves,“ that can separate molecules by size. 16 Holonyaks colleagues thought he wou

According to a survey pub- lished last year, 21 countries have screening progr

18、ammes. Nine of them, including Australia, Canada, the US and Spain, screen women under 50. 2 But the medical benefits of screening these younger women are controversial, partly because the radiation brings a small risk of inducing cancer. Also, younger women must be given higher doses of X-rays beca

19、use their breast tissue is denser. 3 Researchers at the Polytechnic University of Valencia analyzed the effect of screening more than 160,000 women at 11 local clinics. After estimating the womens cumulative dose of radiation, they used two models to calculate the number of extra cancers this would

20、cause. 4 The mathematical model recommended by Britains National Radiological Protection Board (NRPB) predicted that the screening programme would cause 36 cancers per 100,000 women, 18 of them fatal. The model preferred by the UN Scientific Committee on the Effects of Atomic Radiation led to a lowe

21、r figure of 20 cancers. 5 The researchers argue that the level of radiation-induced cancers is “not very significant“ compared to the far larger number of cancers that are discovered and .treated. The Valencia programme, they say, detects between 300 and 450 cases of breast cancer in every 100,000 w

22、omen screened. 6 But they point out that the risk of women contracting cancer from radiation could be reduced by between 40 and 80 percent if screening began at 50 instead of 45, because they would be exposed to less radiation. The results of their study, they suggest, could help “optimize the techn

23、ique“ for breast cancer screening. 7 “There is a trade-off between the diagnostic benefits of breast screening and its risks,“ admits Michael Clark of the NRPB. But he warns that the study should be interpreted with caution. “On the basis of the current data, for every 10 cancers successfully detect

The landers robotic arm delivered the sample Wednesday to an instrument that identifies vapors produced by the heating of samples. “We have water,“ said William Boynton of the University of Arizona, lead scientist for the Thermal and Evolved-Gas Analyzer, or TE

38、GA. “This is the first time Martian water has been touched and tasted. “ The robotic arm is a critical part of the Phoenix Mars mission. It is needed to trench into the icy layers of northern polar Mars and deliver samples to instruments that will analyze what Mars is made of, what its water is like

39、, and whether it is or has ever been a possible habitat for life. The soil sample came from a trench approximately 2 inches deep.
