Australischen Wissenschaftlern ist nach eigenen Angaben ein Durchbruch bei der Entwicklung künstlicher Augen gelungen. Einer Frau mit angeborener Netzhautdegeneration sei erfolgreich ein "früher Prototyp" eines bionischen Auges eingesetzt worden, teilte das australische Wissenschaftskonsortium Bionic Vision Australia (BVA) mit. Der Prototyp soll die Grundlage für das erste bionische Auge bilden, bei dem eine organische Fehlfunktion mittels technischer Sensorik überbrückt wird.

Wireless data transmitters that cost one penny to produce challenge limited QR code technology.
Researchers in Korea have devised a cheap way of transmitting data from objects to mobile phones when swiped. They have printed small "rectennas", a cross between an antenna and an AC/DC current converter, onto plastic foils using electronic inks.
The rectenna uses radio waves emitted from a smartphone to transmit data to it from a tiny chip.
The printed rectennas cost less than one penny per unit to produce and could be used as an alternative to QR codes.
The technology behind them, Near Field Communication (NFC), is already used in devices that enable shoppers to make card payments by touch.

A technology that would enable low-cost, high efficiency solar cells to be made from virtually any semiconductor material has been developed by researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley.
This technology opens the door to the use of plentiful, relatively inexpensive semiconductors, such as the promising metal oxides, sulfides and phosphides, that have been considered unsuitable for solar cells because it is so difficult to taylor their properties by chemical means.

Scientists at the Center for Laser Applications at the University of Tennessee Space Institute in Tullahoma have developed a laser that can target and...
The researchers say this technology is both easier and more cost-effective than the more invasive treatments commonly used. It’s potential use is particularly promising in brain cancer victims due to its non-invasive nature, the laser’s ability to go through thin bone like the skull, and the femtosecond laser radiation which according to Parigger helps, “avoid heating up too many other things that you do not want heated.
” Now that the technology has been developed, Parigger and his colleagues are in the process of commercializing it and making it widely available.

New research from the computer company Dell Inc. finds vast differences in attitudes to technology in education between China and the United States. While six in ten respondents in the United States do not approve of using social media in the classroom, a majority of Chinese respondents have positive feelings about the technology, the survey concluded.
Dell's education wing, Dell Edu, questioned almost 1,600 students, teachers, and parents in China, Germany, and the United States about their technology habits, and put the major findings in a nicely organized infographic (see below.) A report released with the survey also illustrated a few key differences on how technology is utilized for educational purposes:

Une équipe d'astronomes utilisant ALMA (Atacama Large Millimeter/submillimeter Array) a repéré des molécules de sucre dans le gaz entourant une étoile jeune, semblable à notre Soleil.
C'est la première fois que du sucre est trouvé dans l'espace autour d'une telle étoile. Cette découverte montre que les éléments constitutifs de la vie se situent au bon endroit, au bon moment, contribuant aux planètes en formation autour de l'étoile.

Inspiré par la cathédrale Saint-Paul, à Londres, ce capteur composé d’or et de verre détecte instantanément les virus, même les plus petits.
Son principe repose sur un subtil changement de fréquence de la lumière dans le milieu lors du passage du virus. Après quelques ajustements, les scientifiques espèrent l’améliorer pour qu'il repère des molécules, comme les protéines.
