L'ampoule à incandescence, inventée au 19e siècle par Thomas Edison et Joseph Swan, avait un gros défaut : elle gaspillait beaucoup d'électricité. Au 20e siècle, on a trouvé une solution pour la remplacer et économiser l'énergie : la LED (L pour Light, E comme Emitting et D comme Diode ). Aujourd'hui, la lumière LED est partout : dans les phares des voitures, les écrans d'ordinateurs, et bien sûr dans nos ampoules… “Qui a inventé ?” te raconte l'invention de la LED et comment elle fonctionne.

We intuitively notice differences in color and brightness. LEDs can create a more appealing display of light, they help save on our energy costs, and they have a much smaller impact on the environment than other light sources. On October 7, 2014, Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura received the Nobel Prize in Physics for the development of blue light-emitting diodes. Red and green diodes had been around for a long time but without blue light, white lamps could not be created. Despite considerable efforts, both in the scientific community and in industry, the blue LED had remained a challenge for three decades.
Isamu Akasaki (who died earlier this year), Hiroshi Amano, and Shuji Nakamura received the 2014 Nobel Prize in Physics "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources".

Han var inte klassens ljus precis, Shuji Nakamura, under sina barnaår. Betygen var i botten och att han skulle sluta som Nobelpristagare var det nog få som anade då. − Jag bodde på en liten ort och ville vara ute och klättra i bergen eller vara på stranden med mina kompisar, någon tid för att plugga fanns inte, berättar han. Men i andra klass fick han av sin pappa lära sig hur man löser matteproblem. Och det hade han fallenhet för, därför blev matte snart ett favoritämne. Tillsammans med teckning. – Både konst och vetenskap måste kan komma på något eget, gå på sina egna idéer. Där är de ganska lika, konstaterar Shuji Nakamura som numera inte har mycket tid till just teckningen eftersom han lägger så mycket av den på forskningen. Tillsammans med två andra japaner fick han 2014 års Nobelpris för att ha uppfunnit LED-lampan. Camilla Widebeck Camilla.widebeck@sr.se
Hiroshi Amano forskar alla dagar på året utom på nyårsafton då han åker till sin mamma och säger gott nytt år. De nya tekniska framsteg han gör på labbet kan få en avgörande betydelse för att lösa Japans svåra energisituation.Japan brottas med stora miljöutmaningar som engagerar Hiroshi Amano. Sedan kränkraftshaveriet i Fukushima 2011 är alla japanska kärnkraftverk nedstänga, och landet tvingas till stor import av fossila bränslen som smutsar ner miljön.Hiroshi Amano fick i år Nobelpriset i fysik tillsammans med Isamu Akasaki och Shuji Nakamura för uppfinningen av den blå lysdioden, som är grunden för dagens ledlampor som är mycket mer energisnåla än glödlampor och lysrör.Amano har räknat ut att om alla japaner bytte ut sina gamla lampor mot ledlampor skulle landets el-förbrukning minska med över sju procent.

The Nobel Prize in Physiology or Medicine 2014 was awarded with one half to John O'Keefe and the other half jointly to May-Britt Moser and Edvard I. Moser "for their discoveries of cells that constitute a positioning system in the brain".The Nobel Prize in Physics 2014 was awarded jointly to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources".The Nobel Prize in Chemistry 2014 was awarded jointly to Eric Betzig, Stefan W. Hell and William E. Moerner "for the development of super-resolved fluorescence microscopy".A team of scientists took soil samples at 596 sites across New York's Central Park. They analysed the soil samples an discovered 167,000 different kinds of microbes, the vast majority of which were unknown to science.The characteristics of a previous mate can affect the attributes of a fruit fly's offspring. Even if the previous mate is not the genetic father of the offspring.Researchers at the Wake Forest Institute for Regenerative Medicine in Winston-Salem, North Carolina are developing artificial penises developed from a patient's own cells. The team is hoping to receive approval from the US FDA to begin human testing the lab-grown penises within five years.
Esta semana comenzamos con la noticia de un nuevo ensayo de terapia génica para la inmunodeficiencia combinada severa (SCID), que al parecer ha dado buenos resultados. Continuamos con un nuevo avance en el uso de los diodos emisores de luz (LED) que nos sirve de excusa para contarles la historia de estos dispositivos. Una historia que ha culminado con la concesión del Nobel de Física 2014 a Isamu Akasaki, Hiroshi Amano y Shuji Nakamura. Y, para finalizar, una pregunta: ¿A qué se debe el aroma de la cerveza? Estudios realizados han descubierto que su aroma se debe a sustancias químicas volátiles producidas por la levadura Saccharomyzes cerevisiae, una levadura que tiene una sorprendente relación con la mosca de la fruta.
Nobel Prizes 2014 The annual Nobel Prizes for Physiology or Medicine, Physics and Chemistry were announced this week. The Nobel Prize for Physiology or Medicine has been awarded to UK-based researcher Prof John O'Keefe as well as May-Britt Moser and Edvard Moser who discovered the brain's "GPS system". They discovered how the brain knows where we are and is able to navigate from one place to another. Their findings may help to explain why Alzheimer's disease patients cannot recognise their surroundings. The 2014 Nobel Prize for physics has been awarded to Professors Isamu Akasaki, Hiroshi Amano and Shuji Nakamura in Japan and the US, for the invention of blue light emitting diodes (LEDs). This enabled a new generation of bright, energy-efficient white lamps, as well as colour LED screens. The 2014 Nobel Prize in Chemistry has been awarded to Eric Betzig, Stefan Hell and William Moerner for improving the resolution of optical microscopes. This type of microscope had previously been held back by the presumed limitation that obtaining a better resolution than half the wavelength of light would be impossible. But the laureates used fluorescence to extend the limits of the light microscope, allowing scientists to see things at much higher levels of resolution. GAUGE The UK has a database for the amount of greenhouse gases we emit each year - usually measured in Gigatonnes of carbon. It's compiled by adding up emissions from various individual sources - be it a coal-fired power station or a wetland bog. This amount is used worldwide, but it is an estimate. A project called Greenhouse gas UK and Global Emissions, or GAUGE, is - for the first time - verifying these estimates by measuring what's in the atmosphere on a much larger scale. Genetics and Diabetes Type 2 diabetes is globally the fastest growing chronic disease. The World Health Organisation estimates more than 300 million people are currently afflicted, rising to more than half a billion by 2030. It might seem on the surface to be a disease with a simple cause - eat too much & exercise too little - and the basic foundation is a relative lack of the hormone insulin. But as with most illnesses, it's much more complicated, not least because a large number of disease processes are happening all at once. In 2010, a particular gene variant was associated with around 40% of Type 2 diabetics - not directly causal, but this so-called 'risk variant' increases the chance of developing the condition if you have the wrong lifestyle. Research published in the journal Science Translational Medicine this week identifies a drug called yohimbine as a potential treatment to help Type 2 diabetics, one that targets this specific genetic make-up. UK Fungus Day October 12th is UK Fungus Day, a chance for us to celebrate these cryptic, often microscopic, but essential organisms. Usually hidden away inside plants or in soil (or if you're unlucky, in between your toes), fungi have largely been growing below scientists' radars for centuries. Mycologists still don't know anything close to the true number of fungi that exist on the planet. About a hundred thousand have been formally identified, but it's estimated that anywhere from half a million to ten million species may exist. This dwarfs, by several orders of magnitude, how many mammals there are on Earth. And, increasingly, we're realising quite how crucial fungi are to the functioning of our ecosystems. Head of Mycology at The Royal Botanic Gardens Kew, Bryn Dentinger, explains how valuable fungi really are. Producer: Fiona Roberts Assistant Producer: Jen Whyntie.
