As 5G iPhone 12 nears, state of US networks is complicated


Angela Lang/CNET

The next big milestone for 5G in the US is set to arrive tomorrow when Apple announces its rumored first 5G iPhones. The announcement, while still just a rumor, seems even more likely than ever given Apple teased its event with an invite that read “Hi, Speed.” 

But when it comes to 5G in the US, the situation is still not perfectly clear. Over the last few weeks, CNET has been looking at how Verizon, T-Mobile and AT&T’s various 5G networks are performing in several states and cities across the country. While this testing is still ongoing, despite the fact that we’re well over a year into the new 5G era, performance on all three major US carriers is still very much a work in progress with experiences that could vary greatly based on where you live.

The Complicated Camera of Filmmaker Shirley Clarke | by Sarah Cowan

In this year of unprecedented upheaval, ongoing closures due to the pandemic had already forced many cultural organizations to leave behind the status quo when the Black Lives Matter protests began. Reckoning with systemic white supremacy, most have foregone persistent, structural change for a quicker, more visible counterpart: representation. Just over a week after George Floyd’s death, the Criterion Channel, the streaming service of the distributor Criterion Collection, released free of charge for a period (now over) a program of independent films called “Black Lives.”

Most of the films by Black directors in the online program are not actually part of the Criterion Collection catalogue, which is acutely dominated by works by white directors. Neither is Portrait of Jason, the only film on the list by a white, female filmmaker, Shirley Clarke, who was

Evolution of radio-resistance is more complicated than previously thought

The toughest organisms on Earth, called extremophiles, can survive extreme conditions like extreme dryness (desiccation), extreme cold, space vacuum, acid, or even high-level radiation. So far, the toughest of all seems to be the bacterium Deinococcus radiodurans—able to survive doses of radiation a thousand times greater than those fatal to humans. But to this date, scientists remained puzzled by how radio-resistance could have evolved in several organisms on our planet, naturally protected from solar radiation by its magnetic field. While some scientists suggest that radio-resistance in extremophile organisms could have evolved along with other kinds of resistance, such as resistance to desiccation, a question remained: which genes are specifically involved in radio-resistance?

To address this question, the team of Dr. Cox, at the University of Wisconsin-Madison,
