Scientists borrow solar panel tech to create new ultrahigh-res OLED display

Ultra high-res displays for gadgets and tv sets may be coming. 😃

By expanding on existing designs for electrodes of ultra-thin solar panels, Stanford researchers and collaborators in Korea have developed a new architecture for OLED—organic light-emitting diode—displays that could enable televisions, smartphones and virtual or augmented reality devices with resolutions of up to 10,000 pixels per inch (PPI). (For comparison, the resolutions of new smartphones are around 400 to 500 PPI.)

Such high-pixel-density displays will be able to provide stunning images with true-to-life detail—something that will be even more important for headset displays designed to sit just centimeters from our faces.

The advance is based on research by Stanford University materials scientist Mark Brongersma in collaboration with the Samsung Advanced Institute of Technology (SAIT). Brongersma was initially put on this research path because he wanted to create an ultra-thin solar panel design.

An integrated circuit of pure magnons

Researchers led by Technische UniversitĂ€t Kaiserslautern (TUK) and the University of Vienna successfully constructed a basic building block of computer circuits using magnons to convey information, in place of electrons. The ‘magnonic half-adder’ described in Nature Electronics, requires just three nanowires, and far less energy than the latest computer chips.

A team of physicists are marking a milestone in the quest for smaller and more energy-efficient computing: they developed an integrated circuit using magnetic material and magnons to transmit binary data, the 1s and 0s that form the foundation of today’s computers and smartphones.

The new circuit is extremely tiny, with a streamlined, 2-D design that requires about 10 times less energy than the most advanced computer chips available today, which use CMOS technology. While the current magnon configuration is not as fast as CMOS, the successful demonstration can now be explored further for other applications, such as quantum or neuromorphic computing.

Energy scavenging nanogenerator finds power all around us

Imagine a mobile phone charger that doesn’t need a wireless or mains power source. Or a pacemaker with inbuilt organic energy sources within the human body.

Australian researchers led by Flinders University are picking up the challenge of “scavenging” invisible power from low-frequency vibrations in the surrounding environment, including wind, air or even contact-separation energy (static electricity).

“These so-called triboelectric nanogenerators (or TENGs) can be made at low cost in different configurations, making them suitable for driving such as personal electronics (mobile phones), biomechanics devices (pacemakers), sensors (temperature/pressure/chemical sensors), and more,” says Professor Youhong Tang, from Flinders University’s College of Science and Engineering.

Cyberwar 2025

A short story.

A very short story with a long ending.

“What did you do in the Great Cyberwar daddy?”

What can I say? The answer is pretty much what everyone else did, which is try and s urvive. In other words, nothing. The first we all knew about it was when the electricity went off, and did not come back on again. Then other utilities, water, gas and phones. Then the Net itself went down and everyone was in the dark both literally and figuratively. All of that within the space of a few hours. For some it happened overnight and they awoke to a broken world. Most cars still ran, for a while, although GPS was also out. Self driving cars didn’t. When the fuel ran out the gas stations were not pumping (no electricity), the supermarkets along with everyone else could not buy or sell because the payment systems were offline. Within 24 hours looting broke out on a global scale from the richest nations to the poorest and martial law became the new norm.

Ultrafast camera films 3D movies at 100 billion frames per second

In his quest to bring ever-faster cameras to the world, Caltech’s Lihong Wang has developed technology that can reach blistering speeds of 70 trillion frames per second, fast enough to see light travel. Just like the camera in your cell phone, though, it can only produce flat images.

Now, Wang’s lab has gone a step further to create a camera that not only records video at incredibly fast speeds but does so in three dimensions. Wang, Bren Professor of Medical Engineering and Electrical Engineering in the Andrew and Peggy Cherng Department of Medical Engineering, describes the device in a new paper in the journal Nature Communications.

The , which uses the same underlying technology as Wang’s other compressed ultrafast photography (CUP) cameras, is capable of taking up to 100 billion frames per second. That is fast enough to take 10 billion pictures, more images than the entire human population of the world, in the time it takes you to blink your eye.

Elon Musk: The Rise Of Starlink

Might as well make it a movie!

This is the first time ever in my life that I felt frightened while writing a story on Medium. Then, I proofread it and I started sweating all of sudden. Find out for yourself and let me know how you feel! Anyway, recently, I wrote how Elon Musk’s Starlink could potentially take over the whole telecommunications industry, how it can eventually change the digital landscape, and how it can connect our blueprint to the universe. Today, I’m writing how Starlink, along with the right planning, execution, and zero technological compromises, can create not just a new technology, but a whole new way of living.

Imagine wandering the Sahara desert on a weekend trip and suddenly, you feel the urge to capture the moment. So, you pick up your iPhone and take a panoramic picture. Then, imagine sharing that same picture to your friends, to your family, right in that exact moment. Your family decides to FaceTime you and you talk to them for an entire hour while blindly walking around the Sahara desert, drenching in sweat. That’s what it’s like to be Starlink connected. There are no limits to what Starlink can do. Online, wherever you go.

Starlink isn’t just a widespread broadband internet communications system, Starlink is a whole new way of living. It’s a real-world reinvention.

No cellular data issues, no “we’re in the middle of nowhere”, and no “low signal”. You can pretty much end up in the most barbaric place on the earth and still be receiving tweet updates from Trump on Twitter. Just you, your device, and the whole universe. A digital interplanetary being, so to speak. Though, Aliens might hack the satellites and gain information about us. They might take advantage of Starlink as a better way to connect to humans. However, we’re pretty sure Elon will create another company that prevents Aliens from cyberbullying us. Right, Elon?
