A skin-like 2-D pixelized full-color quantum dot photodetector

Full-color photodetectors that can convert light to electric signals without sophisticated color filters and interferometric optics have gained considerable attention for widespread applications. However, technical challenges have impeded scientists from combining multispectral semiconductors and improving photon-transfer efficiency to form high-performance optoelectronic devices in practice. In a recent report on Science Advances, Jaehyun Kim and a research team in materials science and engineering in the U.S. and Korea, described a low-temperature fabricated (150 degrees C), two-dimensionally (2-D) pixelated, full-color photodetector using monolithic integration of quantum dots coupled to amorphous indium-gallium-zinc-oxide semiconductors.

Researchers crack Newton's elusive three-body problem

It's been nearly 350 years since Sir Isaac Newton outlined the laws of motion, claiming "For every action, there is an equal and opposite reaction." These laws laid the foundation to understand our solar system and, more broadly, to understand the relationship between a body of mass and the forces that act upon it. However, Newton's groundbreaking work also created a pickle that has baffled scientists for centuries: The Three-Body Problem.

Research reveals a singular moment: When a bubble breaks free

Understanding how a drop or bubble suspended in a larger mass of fluid divides into multiple pieces is invaluable for engineers designing chemical reactors, engines and ships, as well as for geoscientists studying interactions of oceans and the atmosphere. But the difficult math underlying the phenomenon has forced scientists to rely on idealized systems that lack real-world nuance. Now, researchers at Princeton University have described the breakup of bubbles surrounded by turbulent flows like those found in industrial processes or in nature.

Topological materials for information technology offer lossless transmission of signals

New experiments with magnetically doped topological insulators at BESSY II have revealed possible methods of lossless signal transmission that involve a surprising self-organization phenomenon. In the future, it might be possible to develop materials with such characteristics at room temperature that can be used as processing units in quantum computing, for example. The study has been published in Nature.

New clues on dark matter from the darkest galaxies

They are called low-surface-brightness galaxies and it is thanks to them that important confirmations and new information have been obtained on one of the largest mysteries of the cosmos: dark matter. "We have found that disc galaxies can be represented by a universal relationship. In particular, in this study we analysed the so-called Low-Surface-Brightness (LSB) galaxies, a particular type of galaxy with a rotating disc so called because they have a low-density brightness," says Chiara di Paolo, astrophysicist at SISSA and lead author of a study recently published in MNRAS together with Paolo Salucci (astrophysicist at SISSA) and Erkurt Adnan (Istanbul University).

A more intuitive online banking service would reinforce its use among the over-55s

Experts from the MAD (Analytical and Digital Marketing) Research Group from the University of Seville have drawn attention to the fact that the very nature of online banking, according to the data analysed, is the cause of the reticence of the over-55s to use it as they do not feel comfortable navigating the 'digital world.' To combat this situation, the experts recommend developing more intuitive applications with appropriate signposting and instructions to help avoid errors. This would make it possible for them to know that they were doing the right thing, so reinforcing their confidence.

▼ Google Stadia should have stayed in beta

I have been playing a lot of Stadia lately. Not because I think Google's game streaming service is amazing, but because in order to get anything out of Assassin's Creed Odyssey (about which I have many thoughts) you have to play a lot. It's a long game.

I'll put down a few more points about my experiences with Stadia — and how it's the worst gaming launch since the Xbox One and maybe before that, after the links.

Mossberg: Tim Cook's Apple had a great decade but no new blockbusters

Essential reading from Walt Mossberg himself. I expect (actually I know, because the tweets have happened) it will be a little polarizing. But I think it's a cipher: people will be angered because it doesn't give enough credit to AirPods and the Apple Watch, other people will think it gives too MUCH credit to other products.

I think it's spot-on. The MacBook line wasn't just a miss, it was a years-long blunder. And while Apple's new products are very successful, nothing will ever match the iPhone.

Google employee says she was fired for sending internal pop-ups about labor rights

AI super resolution lets you 'zoom and enhance' in Pixelmator Pro

Enhance!

Research into super resolution has been ongoing for some time now, with tech companies like Google and Nvidia creating their own algorithms in the past few years. In each case, the software is trained on a dataset containing pairs of low-resolution and high-resolution images. The algorithm compares this data and creates rules for how the pixels change from image to image. Then when it's shown a low-resolution picture it's never seen before, it predicts what extra pixels are needed and inserts them.

The Alienware m17 gaming laptop is $1,150 off right now

Alienware's m17 gaming laptop with an Nvidia RTX 2080 Max-Q graphics chip is steeply discounted right now at Dell. It has one of Intel's older 8th Gen CPUs, but otherwise its 16GB of RAM and 512GB of fast PCIe SSD storage will ensure some great performance for far less cash required than usual. You can get it for just $1,699.99 with the offer code AWAFF1150, but Dell warns that quantities are limited at this price.

Google Stadia should have stayed in beta

I have put in enough hours in enough conditions to say that this is a beta product and Google should have labeled it as such and launched it differently. Because even in the best conditions, this ain't the best. I have what I think is probably the most ideal connection imaginable: Google Fiber (technically WebPass) in Oakland, 500 up and down with very low latency. And I still get weird internet lag jitters sometimes. Woof.

Woof but also, shrug? I find that by and large it works well enough for me and I really do love that I can play it on many different devices (including a Surface Go!). The more I think about it, though, the more I realize that as with the Xbox One, the biggest problem is simply the size of the library.

So while I'm happy that Google Stadia finally keeps a promise with three new games and its first exclusive feature, I think it's way too little — though not necessarily too late. If Google can do even half of what Nintendo achieved in terms of growing the Switch library, it has half a chance.

All the Games Of The Year lists are coming out (here's ours) and I can't tell you how many times I've thought "Huh I might want that on Stadia rather than PlayStation" and realized that, haha no, Stadia is still a beta product with a beta product-sized library.

Google has thus far failed to ship a hunk of plastic that helps you attach your phone to a controller. A thing that should have been packed in with the original controller, a thing that costs $15 for some reason, a thing that it nothing more than molded plastic and a spring. So, you know, execution still not this division's strong suit. That's also in beta.

Thing is, Google has asked for and received Real Money from people, so treating Stadia like a beta isn't just embarrassing, it's irresponsible. Google should have tried an entirely different way of launching this service. Call it a beta for real, make it an invite system to have it seem more exclusive, and don't charge money for it until it's out of beta.

Hindsight is 20/20 (or maybe it's 4K with low latency), though. All we can hope for now is that Google will fix it quickly. Maybe by the time I get through Assassin's Creed, it will be better. That's probably too long to wait, though.
