Symbiotic fungi have a key role in soil ecosystems and inoculating plants with them has been claimed to benefit their growth. But scientific evidence shows a very complex picture; which might surprise you.
Today, countless electronic devices have touchscreens, including smart phones, tablets and smart home appliances. Touchscreen interfaces have become some of the most common means for users to communicate with and browse through their devices.
With this in mind, a research group at imec in Belgium has recently carried out a study exploring the potential of touchscreen interfaces for enabling the simple transfer of data to and from devices connected to the internet. In a paper published in Nature Electronics, the team showed that commercial touchscreens can be used as reader interfaces for capacitive coupled data transfer using a 12-bit, thin-film identification tag powered by a battery or photovoltaic cell.
“Our field of expertise is flexible electronics for IoT and Internet of Everything applications,” Kris Myny, principal scientist at imec and one of the researchers who carried out the study, told Tech Xplore. “In this field, we look into thin-film circuits, i.e. flexible RFID tags that can be embedded in objects and communicate to RFID and/or NFC readers. Based on this, our next step was to investigate whether we could expand the number of readers.”
A Chinese facial-recognition database with information on thousands of children was stored without protection on the internet, a researcher discovered, raising questions about school surveillance and cybersecurity in China.
The cache was connected to a surveillance system labeled “Safe School Shield” and contained facial-identification and location data, according to Victor Gevers, a researcher at the Dutch nonprofit GDI Foundation, which scans the internet for vulnerabilities and flags them to owners for fixing.
WASHINGTON: Google is planning to “render obsolete” a key tool advertisers use to track people around the web, increasing user privacy but also disrupting the marketers and publishers who rely on the search giant’s ad products.
“Over the next two years Google intends to stop supporting third-party cookies in its Chrome browser,’’ the Alphabet Inc unit said in a blog post on Tuesday.
Cookies are little bits of code that stick in peoples’ browsers and follow them around the web and are a core part of the online advertising landscape. They allow advertisers to target people with ads for websites they previously visited and make it easier to determine how effective certain ads were in getting internet surfers to buy something.
New models show how to keep turn forces that usually degrade satellite orbits into supportive ones that keep them propped up in space.
In a new report published on Scientific Reports, Milan M. Milošević and an international research team at the Zepler Institute for Photonics and Nanoelectronics, Etaphase Incorporated and the Departments of Chemistry, Physics and Astronomy, in the U.S. and the U.K. Introduced a hyperuniform-disordered platform to realize near-infrared (NIR) photonic devices to create, detect and manipulate light. They built the device on a silicon-on-insulator (SOI) platform to demonstrate the functionality of the structures in a flexible, silicon-integrated circuit unconstrained by crystalline symmetries. The scientists reported results for passive device elements, including waveguides and resonators seamlessly integrated with conventional silicon-on-insulator strip waveguides and vertical couplers. The hyperuniform-disordered platform improved compactness and enhanced energy efficiency as well as temperature stability, compared to silicon photonic devices fabricated on rib and strip waveguides.
Academic and commercial efforts worldwide in the field of silicon photonics have led to engineer optical data communications at the Terabit-scale at increasingly lower costs to meet the rapidly growing demand in data centers. Explosive growth in cloud computing and entertainment-on-demand pose increasingly challenging costs and energy requirements for data transmission, processing and storage. Optical interconnects can replace traditional copper-based solutions to offer steadily increasing potential to minimize latency and power consumption, while maximizing the bandwidth and reliability of the devices. Silicon photonics also leverage large-scale, complementary metal-oxide semiconductor (CMOS) manufacturing processes to produce high-performance optical transceivers with high yield at low-cost. The properties allow applications of optical transceivers (fiber optical technology to send and receive data) to be increasingly compelling across shorter distances.
More than three decades ago, physicist Richard Soref identified silicon as a promising material for photonic integration. Leading to the present-day steady development and rapid production of increasingly complex photonic integrated circuits (PICs). Researchers can integrate large numbers of massively-parallel compact energy-efficient optical components on a single chip for cloud computing applications from deep learning to artificial intelligence and the internet of things. Compared to the limited scope of commercial silicon photonic systems, photonic crystal (PhC) architectures promise smaller device sizes, although they are withheld by layout constraints imposed by waveguide requirements along the photonic crystal’s axis. Until recently, photonic band gap (PBG) structures that efficiently guide light were limited to photonic crystal platforms. Now, newer classes of PBG structures include photonic quasicrystals, hyperuniform disordered solids (HUDs) and local self-uniform structures.
SET-listed satellite service provider Thaicom is in talks with three foreign companies on partnership deals to operate ground stations for satellite data transmission as the government works towards opening the satellite industry to private operators through a licensing regime.
The ground stations, known as satellite gateways, are responsible for transmitting data to and from the satellite to the local area network. The antennas and equipment for converting the radio frequency signal to an internet protocol signal for terrestrial connectivity are already installed.
The deals are expected to be concluded this year, with operations kicking off next year, according to Thaicom chief executive Anant Kaewruamgvongs.
No matter how cheap or fast paid internet service gets, the Internet of Things (IOT) won’t take wings until we have ubiquitous access to a completely decentralized, open-standard network that does not require a provider subscription. This month, we may be a step closer.
Let’s talk about internet connected gadgets. Not just your phone or PC—and not even a microwave oven or light bulb. Instead, think of everyday objects that are much smaller and much less expensive. Think of things that seemingly have no need to talk with you.
Now think of applications in which these tiny things need to communicate with each other and not just with you. Think of the cost of this “thing” compared to the added cost of continuous communications. Do so many things really need to talk in the first place?
First, there were Trackers…
