In the period after the discovery of high-temperature superconductors, there wasn’t a good conceptual understanding of why those compounds worked. While there was a burst of progress towards higher temperatures, it quickly ground to a halt, largely because it was fueled by trial and error. Recent years brought a better understanding of the mechanisms that enable superconductivity, and we’re seeing

Initial Google Pixel 5 review: The best premium Pixel


The Google Pixel has been a premium product since its inception in 2016. Google wanted the series to rival the iPhone. That is, to have such a tight integration between software and hardware that the experience wasn’t just usable, it was delightful. Until now, however, the company has demanded a premium price to make this happen, but the fact is, Google just doesn’t yet have the die-hard fan base that Apple does. Because of this, Google has had a hard time moving units over the years.

This year, the Mountain View company is taking a different approach. Google is a

Google Pixel 4a 5G review: Perfectly balanced


Branding is hard. Making any product stand out among a sea of competitors is a tough task, but in the oversaturated smartphone market that challenge is dialed up to 11. Enter the Google Pixel 4a 5G — the search giant’s latest offering in the increasingly competitive sub-$500 price tier.

Looking at the name, you’d be excused for thinking this is an iterative update on the Pixel 4a — Google’s endlessly delayed budget phone that finally dropped in August of this year. And while yes, the Pixel 4a 5G does feature support for next-generation data speeds, that barely tells half

OnePlus 8T review: Not enough to stand out


OnePlus is back with the OnePlus 8T, its fourth release this year. “Ultra Stops At Nothing” is the tagline this time around. For a phone that brings no performance jump over its predecessor, those are bold words. Can the new 120Hz OLED display and Warp Charge 65 charging tech be enough? Find out in Android Authority’s OnePlus 8T review.

About this OnePlus 8T review: I spent a week with the OnePlus 8T as my main device. It was running Android 11 with Oxygen OS 11. The build number was 11.KB05BA. OnePlus supplied the OnePlus 8T review unit to Android Authority

iPhone 12 vs. Samsung Galaxy S20 vs. Pixel 5 and more: specs comparison


Apple’s new iPhones have arrived (even if they’re a bit later than usual). And this year, Apple has launched four new phones: the iPhone 12, 12 mini, 12 Pro, and 12 Pro Max, its first iPhones with 5G and what Apple claims are the fastest smartphones ever made.

The new iPhone 12 and 12 mini effectively replace last year’s iPhone 11, but this year Apple is offering its cheaper iPhone in two sizes (something that the company has done with its higher-end models for the last two years). It’s also made some big upgrades on the hardware front: the display
