. >> 2014 nobel prize in physics to professor isamu akasaki, professor hiroshi amano at nagoya university japan, and professor shuji nakamura at university of california santa barbara. for the invention of efficient blue light emitting diodes which has enabled bright and energy saving white light sources. >> members of the royal swedish academy of scientists made the announcement in stockholm. akasaki teaches at major university in nagoya city. hiroshi amano is a professor at nagoya university. nakamura is a professor at the university of california santa barbara. in 1989, akasaki and amano used crystals to help develop a unique semiconductor that emitted blue light. knack rura built on that achievement to create brighter blue l.e.d.s that were capable of being used in electronic products. >>> wow. congratulations. and that's all for this edition of "newsline." i'm miki yamamoto from tokyo. we'll have more news for you at the top of the hour. thanks for watching nhk world.gç >> the battle for bonnie continues. islamic state militants have raised their black flag on several buildings on tw

isamu akasaki, hiroshi amano and shuji nakamura carried out ground breaking research that led to the creation of blue light emitting diodes or l.e.d.s. what they invented is now used in many electronic products. members of the royal swedish academy of sciences made the announcement in stockholm. akasaki teaches in central japan. amano is a professor at nagayo university and nakamura is a professor at university of california, santa barbara. in 1989, akasaki and amano used gallium nitride crystals to develop a semiconductor that emitted blue light. nakamura built on that achievement to create brighter blue l.e.d.s capable of being used in electronic products. the academy members said it contributed to help saving the earth's resources and they say it promises a better quality of life for 1.5 billion people around the world. it's the first time in six years that japanese scientists have won the award. and it brings the number of physics laureates from japan to ten. [ applause ] >> translator: i was half surprised but there is nothing more honorable than this. at first people said no on

the trio, isamu akasaki, hiroshi amano, and shuji nakamura won the prestigious award for inventing the blue-light emitting dye odds found in smartphones to televisions. you probably know it as an l.e.d. right. the professors created the first l.e.d. in the 1990s, after scientists struggled to do that for decades. the breakthrough allowing for energy efficient longer lasting white light found in electronic gadgets and light bulbs. it lasts 10 times longer than fluorescent light. and 10 times longer than the ones we grew up with. you can't underestimate the financial impact. to help to explain it we bring in tech correspondent jacob ward. help us out. let's talk about the specifics. why are breakthrough? >> there's the joke, whoever can invent a better light bulb is the better person. it's hard to do. the original filament incandescent light bulbs gave off heat. they burnt your happened when you unviewed them. you have to put current into the metal and gives off heat and waste. fluorescent light bulbs, more efficient, but have other bad properties and involve a great deal of gas, environ

isamu akasaki, hiroshi amano, and shuji nakamura split the prize for developing the blue l.e.d. lights we see on the tvs and smartphones. red and green l.e.d.s were developed in the 1960, it took 20 years for the blue light to be develop. they combine to create white light similar to the sun at a more efficient rate, 20 times more than traditional light sources. this is allowing l.e.d. lights to be used to illuminate poor airs. they'll split the $1.1 million prize. that's some of what is happening around the world. >>> coming up ebola outrage. eight out of 10 registered nurses in the u.s. says hops have not given them policy guidance. should we trust c.d.c. officials when they say they know how to manage the problem. >>> and a shocking first hand act of a drug leak and terrorist. a d.e.a. agent that went under cover for nearly three decades joins us. >> and harmeli aregawi is tracking the top stories on the web. what is trending. >> so many stories about bad cops is making the news. one that is making its way around social media is an occupying cop, giving a struggling mother wh
