If you’ve ever wished you could print photos directly from your cell phone, a new mobile photo printer from Polaroid is coming that can do just that. Perhaps even more intriguing is the technology the printer uses: it´s inkless. Designed by ZINK (“Zero-Ink”) Imaging, the ZINK printer concept doesn´t require ink cartridges or even dye rolls. Instead, it incorporates dye crystals inside the specially patented ZINK paper, secured underneath a glossy protective layer. When heat from the printer is applied to the cyan, yellow, and magenta crystals in the paper, the appropriate crystals are “melted” to release color.While ZINK Imaging has developed the technology (with more than 100 patents and counting), the company is partnering with others to build and release the actual products. The first products that will feature ZINK technology will be Polaroid´s Mobile Photo Printer and Integrated Digital Camera and Printer. Cell phones and cameras can be directly connected to the Mobile Photo Printer via Bluetooth or USB, providing 2 x 3 inch prints. (The printer itself measures just 4.7- by 2.8- by 0.9-inches.) The Mobile Photo Printer should be released sometime this spring, and Newsweek reports that it will sell for $150.ZINK has recently announced partnerships with three other companies: Alps Electric Co, Ltd., Foxconn Technology Group, and TOMY Company, Ltd. Most likely, future incarnations using ZINK technology will offer larger paper sizes (4 x 6 inches and beyond). As PC Magazine points out, ZINK also has the capabilities of creating ZINK printers embedded into not just cameras, but also cell phones and notebook computers, without adding much weight or bulk.ZINK’s goals for its printers are to provide high quality photos at an affordable price, while incorporating the convenience due to its new technology. In the future, the company hopes to offer something for everyone.More information: www.zink.com Citation: Inkless ‘Zink’ Printer Fits in Your Pocket (2008, January 29) retrieved 18 August 2019 from https://phys.org/news/2008-01-inkless-zink-printer-pocket.html Polaroid´s Mobile Photo Printer uses ZINK (“zero-ink”) technology to print 2 x 3 color photos.

The team notes that cannibalism has been found in over 300 species, which of course, includes humans. While it is not known if parasitic infection may be behind some cases of human cannibalism, the researchers note that one very common type of parasite that infests between 10 and 20 percent of the British population is suspected of making people less risk averse, which could perhaps allow people to resort more easily to cannibalism under extreme circumstances. Scientists have known for some time that parasitic behavior can cause a host to modify its behavior in ways that benefit the parasite. One parasitic wasp for example, stuns its ladybug host into serving as a guard for its larvae, and in another case a type of tapeworm causes a host fish to swim faster or slower to reduce or increase its chances of being eaten by larger prey. Now it appears that certain types of parasites can also increase the chances of a host becoming cannibalistic.The team was studying the shrimp Gammarus duebeni celticus, and the parasites that infest them, known as Pleistophora mulleri—very tiny creatures that make themselves at home in the shrimp’s muscles. Because they are so small, one or two of the parasites do not have much of an impact, but as they multiply to thousands, the team found, they can have a dramatic impact on how the shrimp host behaves. Adult shrimp that were heavily infested were found to eat substantially more of their own young, than did those that were not infested.The team believes the cannibalistic behavior is caused by the increased food demand of the parasite, and the reduced ability of the host to feed itself due to muscle damage from the parasite. Eating its own young provides an easy meal and helps to sate the demands of the parasite, thus, it makes sense—at least for the shrimp. (Phys.org)—A small team of researchers with members from institutions in the U.K. and South Africa, has found evidence that suggests parasites infecting a certain type of shrimp leads to a higher incidence of cannibalism. In their paper published in Royal Society Open Science, the team discusses their study of a type of shrimp that lives off the coast of Ireland and what they discovered about parasites that infest them.

Credit: University of Leeds More information: Mandy Bunke et al., ‘Eaten alive: cannibalism enhanced by parasites,’ Royal Society Open Science (2015). dx.doi.org/10.1098/rsos.140369AbstractCannibalism is ubiquitous in nature and especially pervasive in consumers with stage-specific resource utilization in resourcelimited environments. Cannibalism is thus influential in the structure and functioning of biological communities. Parasites are also pervasive in nature and, we hypothesize, might affect cannibalism since infection can alter host foraging behaviour. We investigated the effects of a common parasite, the microsporidian Pleistophora mulleri, on the cannibalism rate of its host, the freshwater amphipod Gammarus duebeni celticus. Parasitic infection increased the rate of cannibalism by adults towards uninfected juvenile conspecifics, as measured by adult functional responses, that is, the rate of resource uptake as a function of resource density. This may reflect the increased metabolic requirements of the host as driven by the parasite. Furthermore, when presented with a choice, uninfected adults preferred to cannibalize uninfected rather than infected juvenile conspecifics, probably reflecting selection pressure to avoid the risk of parasite acquisition. By contrast, infected adults were indiscriminate with respect to infection status of their victims, probably owing to metabolic costs of infection and the lack of risk as the cannibals were already infected. Thus parasitism, by enhancing cannibalism rates, may have previously unrecognized effects on stage structure and population dynamics for cannibalistic species and may also act as a selective pressure leading to changes in resource use.Press release Journal information: Royal Society Open Science Study shows parasites may resort to sabotage if there are conflicting interests with a host Explore further © 2015 Phys.org Citation: Researchers find instance of parasites fueling cannibalism (2015, March 18) retrieved 18 August 2019 from https://phys.org/news/2015-03-instance-parasites-fueling-cannibalism.html Gammarus duebeni pair.

Scheme of a waveguide-integrated plasmonic nanoantenna for mode-selective polarization (de)multiplexing. The device couples light of orthogonal polarizations into different directions and modes of the underlying silicon waveguide. Credit: Science Advances (2017). DOI: 10.1126/sciadv.1700007 (Phys.org)—A team of researchers from several institutions in Germany and Australia has developed an optical high-bitrate nanoantenna that they used with an optical waveguide. In their paper published on the open access site Science Advances, the team explains how their device works and their plans for improving it to make it more commercial. Engineers invent method to control light propagation in waveguides Imprinting an optical nanoantenna onto an optical waveguide, as the researchers note, is still a new idea—most such efforts have involved devices that couple light to a waveguide mode. In this new effort, the researchers have advanced the idea with a device capable of sorting and routing streams of information that has been encoded into a beam of light using varying polarizations. What’s more, they have found a way to do it using optical components that are much smaller than other devices—down to sub-micrometer size, which opens the possibility of high-density photonics components on a chip. They report that their device is capable of directional, polarization-selective and mode-selective routing on a silicon rib waveguide. Their efforts, they note, demonstrate that nanoantenna integration into waveguides holds the potential for developing new high-bitrate telecommunications applications.An optical nanoantenna works by taking advantage of plasmonics—light striking a metal causes electrons on the surface to move in plasmon waves. These have wavelengths that are smaller than the smallest light wavelength, which means researchers can create devices so small that they are able to convey information using photons. One of the goals of researchers in this field is to create integrated circuits that process and move information using photons instead of electrons. Achieving such a goal requires optical waveguides capable of routing information represented by photons. © 2017 Phys.org Explore further This document is subject to copyright.

High–bit rate ultra-compact light routing with mode-selective on-chip nanoantennas, Science Advances (2017). DOI: 10.1126/sciadv.1700007AbstractOptical nanoantennas provide a promising pathway toward advanced manipulation of light waves, such as directional scattering, polarization conversion, and fluorescence enhancement. Although these functionalities were mainly studied for nanoantennas in free space or on homogeneous substrates, their integration with optical waveguides offers an important “wired” connection to other functional optical components. Taking advantage of the nanoantenna’s versatility and unrivaled compactness, their imprinting onto optical waveguides would enable a marked enhancement of design freedom and integration density for optical on-chip devices. Several examples of this concept have been demonstrated recently. However, the important question of whether nanoantennas can fulfill functionalities for high-bit rate signal transmission without degradation, which is the core purpose of many integrated optical applications, has not yet been experimentally investigated. We introduce and investigate directional, polarization-selective, and mode-selective on-chip nanoantennas integrated with a silicon rib waveguide. We demonstrate that these nanoantennas can separate optical signals with different polarizations by coupling the different polarizations of light vertically to different waveguide modes propagating into opposite directions. As the central result of this work, we show the suitability of this concept for the control of optical signals with ASK (amplitude-shift keying) NRZ (nonreturn to zero) modulation [10 Gigabit/s (Gb/s)] without significant bit error rate impairments. Our results demonstrate that waveguide-integrated nanoantennas have the potential to be used as ultra-compact polarization-demultiplexing on-chip devices for high–bit rate telecommunication applications.Press release The new device was created using extremely small gold bars, which, the team notes, presents a problem for commercialization—the precious metal must be replaced with another to make it CMOS compatible. The team also plans to improve the transmission efficiency of their device, and are considering attempting to create circuits by joining their devices together.
