How to Make Coloured Electronic Paper?

Some new technologies appear from nowhere. Others are heralded by such long fanfares that it seems they will never arrive. Electronic paper is surely in the second category. The idea of a display screen that has the clarity and flexibility of paper has been around for at least a decade. It has found a few niche, black-and-white applications in mobile phones and ¡§electronic books¡¨. As a mass-market, full-colour product, however, it has conspicuously failed to show up.

A Warm South Pole on Neptune

An international team of astronomers using ESO's Very Large Telescope has discovered that the south pole of Neptune is much hotter than the rest of the planet. This is consistent with the fact that it is late southern summer and this region has been in sunlight for about 40 years.

Infinera's Photonic Integrated Circuits Demonstrated Transmission of 40 Gb/s Over Transoceanic Distance

Infinera has demonstrated the transmission of 40 Gigabit/second (Gb/s) services over a distance of 8,477 kilometers across a transoceanic network spanning Europe and the U.S., a record distance for a field trial involving 40 Gb/s services. Infinera believes that this demonstration shows how key Infinera technical innovations can enable service providers to offer new high bandwidth services such as 40 Gb/s or OC-768/STM-256 Packet over SONET (POS) services today, and 100 Gigabit Ethernet (100GbE) in the future, over existing infrastructures with less cost and greater flexibility than the 40 Gb/s solutions offered by traditional WDM providers.

All-Purpose Interference Filters with Variable Transmission Characteristics

Applications such as analytical and environmental science, medical and biotechnology, and genetics and fluorescence measurement could all benefit from Schott¡¦s latest interference filters. Called ¡§Veril¡¨ filters, the product uses thin layers to either transmit or reflect various colors of the spectrum.

Simple and Inexpensive Optical Imaging System Providing Real-Time Mapping of Animals' Internal Organs

The new system, which researchers Elizabeth Hillman of Columbia University and Anna Moore of the Harvard Medical School have dubbed a dynamic fluorescence molecular (DFM) imager, is currently being used to monitor the organs of laboratory mice. Hillman is now collaborating with Cambridge Research & Instrumentation to develop a commercial imaging platform that could have applications in drug testing and in the search for tumour-killing cancer treatments.

Alternative to Conventional Lighting - Efficient and Environmentally Friendly White Organic LED

Researchers in Hong Kong claim to have developed the highest power efficiency non-doped white organic light emitting device (WOLED) made using a single white-emitting material. They believe that their high purity, color stable device, surpasses existing WOLEDs and is a more efficient and environmentally friendly alternative to inorganic LEDs.
