Silicon might be the de facto standard for today's computing, but it might be due for a change if new research from MIT, the University of Houston, and other institutions is to be believed.

Cubic boron arsenide, a chemical compound cooked up from a combination of boron and arsenic, could apparently be a better semiconductor, bypassing some of the weaknesses of silicon when it comes to heat sensitivity. 

In fact, according to research published in Science,  Cubic boron arsenide has the "third-best thermal conductivity of any material — next to diamond and isotopically enriched cubic boron nitride".

Is this the future?

The research said that more work would be needed to determine whether cubic boron arsenide can be "made in a practical, economical form, much less replace the ubiquitous silicon". 

But even in the near future, the material could find "some uses where its unique properties would make a significant difference" according to the researchers. 

That being said, the research outlined the vast potential that the compound has.

Cubic boron arsenide is apparently much more accommodating to “holes” — electrons’ positively charged counterparts.

The lower heat sensitivity of cubic boron could also make a huge difference.

“Heat is now a major bottleneck for many electronics,” said MIT postdoc Jungwoo Shin who co-authored the paper. “Silicon carbide is replacing silicon for power electronics in major EV industries including Tesla, since it has three times higher thermal conductivity than silicon despite its lower electrical mobilities". 

"Imagine what boron arsenides can achieve, with 10 times higher thermal conductivity and much higher mobility than silicon. It can be a game changer.”

It's not just cubic boron arsenide that is threatening to overtake silicon one day.

Researchers from the University of Illinois built 4-bit and 8-bit processors entirely out of plastic, which apparently had an 81% success rate, at least for the 4-bit models. 

It's important to note that silicon never really had a monopoly in the world of semiconductors anyway.

Gallium arsenide, built from gallium and arsenic, is widely used in lasers as an alternative to silicon.

Latest Tech News

There's finally some news on Intel Arc Alchemist's release date, but not the kind that anybody outside of Nvidia and AMD really wanted to hear: Arc Alchemist and Battlemage might get the ax entirely over unfixable hardware flaws that are kneecapping their performance, and it's threatening to scrap Intel's entire Arc discrete graphics line.

This report comes from YouTuber Moore's Law is Dead, and it is a doozy, full of internal politics, bitterness, and recriminations at Intel over the company's graphics unit being unable to actually deliver the discrete graphics cards that have been hyped up for more than a year.

I highly suggest you watch the video for all the tea, but the key takeaway is that internal sources at Intel told Moore's Law is Dead that there is a potentially unfixable hardware flaw in the Arc Alchemist GPU that the graphics unit had hoped to address using a driver fix, but that fix isn't working. That's the hardware challenge, reportedly, and it might extend to Battlemage as well. If this is true, then it definitely would explain why the Intel Arc launch has been, well, strange.

Where things get real messy is that the Intel Arc graphics unit has been doing PR for Arc Alchemist cards that Intel told investors would have launched to western markets by the end of the second quarter of this year. We are now in Q3, the cards have not launched, and Intel insiders outside of the graphics unit are angry that the graphics unit is doing PR saying that cards are ready when they do not appear to be ready at all.

On top of that, there are apparently issues with Intel AIB partners who, according to a purportedly leaked presentation, were lined up to produce Intel Arc cards starting at the end of July. Moore's Law is Dead is saying that none of the board partners he's spoken with have any idea what is going on, and the AIBs are not at all happy with the situation.

Finally, cue Pat Gelsinger, Intel's CEO, who is reportedly now looking into whether the entire Arc discrete graphics project should just be canceled. As Moore's Law is Dead highlights in the video, there were some strong hints of this frustration during Intel's earnings call this week where Gelsinger acknowledged the disappointing earnings and said that while the global chip shortage was still very much an issue, problems of "execution" on Intel's part also contributed to Intel's falling far short of earnings expectations for Q2.

So, that is more or less the report that Moore's Law is Dead presented, and we have not independently confirmed anything ourselves, though we have reached out to Intel for comment and will update this story if and when we hear back from the company.

So, um, when exactly are we going to see these cards? Asking for a friend

It's still too soon to tell what exactly is happening with Intel Arc, but Moore's Law is Dead's report isn't coming out of nowhere. Intel Arc Alchemist is more than a month late from its target launch date in the US, and the smattering of cards we have seen in the wild have been bizarrely inconsistent, with performance throttling from single lines of code to the head-scratcher that Intel's first discrete graphics card was going to launch in China and India first.

Fair enough, those are two of the largest consumer markets in the world, and China has more than enough tech heads that want to get their hands on some Intel cards, too, but there's no way to shake an uneasy feeling about all this. This doesn't feel like a well-planned product launch, and the recent PR appearances by some Intel reps on the graphics card team invariably fail to answer the question everybody is asking, which is when are these cards coming out? 

Sure, they're available in China and India, so they are technically "out", but I mean globally. That's a question Intel can't seem to answer right now, and it's a damned shame if there ever was one.

Budget builders can't catch a break

Earlier this week, I wrote about the problem of semiconductor manufacturers like Nvidia, AMD, and, yes, Intel, pursuing increasingly more powerful hardware in an arms race with rivals and how that is having very real consequences in the real world. The wholesale abandonment of any pretense towards energy efficiency in all but the most basic Chromebook processor is disturbing.

Not as bad but still awful is the pricing out of an increasing number of people, mostly gamers but also academics and researchers who actually do need high-performance GPUs for scientific work, and who are simply not the target consumers for these cards anymore. 

There are rumors that Nvidia's RTX 4090, when it launches later this year, will cost less than the RTX 3090. That's a nice start, but the RTX 3090 costs $1,499. Will the RTX 4090 cost $1,449? $1,299? You know what else costs $1,499? A 3-credit-hour graduate course at the City University of New York-Brooklyn College. The cost of the RTX 3090 was obscene, frankly, when it launched, and it remains so.

It used to be you could rely on AMD to come in with a lower-cost option for the rest of us who couldn't afford a GeForce card anymore, but that ship is sailing, too. There is still value to be found among graphics cards out there, which is why the Nvidia RTX 3060 Ti is at the top of our best graphics card list, but that herd is thinning rather quickly.

That, ultimately, was my hope for Intel Arc. As a newcomer to the graphics card cold war between Nvidia and AMD, there was room for Intel to sweep in with a solid budget to lower-midrange lineup and clean up on that cost-conscious-friendly market. I hope Moore's Law is Dead turns out to be dead wrong on this, but it's looking rather iffy out here for all the gamers stuck on aging hardware like the RTX 1050 and AMD RX 470.

If Intel does end up shelving or axing Arc entirely, it will be a real blow to budget-minded gamers and builders out there, and the budget side of things could really use a solid win these days.

U.S. Senator Sherrod Brown (D-OH) has sent a letter to the CEOs of Apple and demanding the companies explain how they review and approve mobile apps for cryptocurrency trading and storing. 

The letter comes a few days after the FBI warned retail investors that their peers lost more than $42 million on crypto scams in less than a year.

“Crypto mobile apps are available to the public through app stores, including Apple’s App Store,” the senator wrote to Cook on Thursday, according to The Verge. “While cryptocurrency apps have offered investors easy and convenient ways to trade cryptocurrency, reports have emerged of fake crypto apps that have scammed hundreds of investors.”

Preventing fraud

Brown also wants to know if the companies monitor the apps they list in the stores, and how they stop them from “transforming” into phishing scams, as well as if the two companies notified their users about fraudulent crypto apps in the past.

“While firms that offer crypto investment and other related services should take the necessary steps to prevent fraudulent activity, including warning investors about the uptick in scams, it is likewise imperative that app stores have the proper safeguards in place to prevent against fraudulent mobile application activity,” the letter adds.

So far, Apple and Google have stayed silent, although they do have until August 10 to reply.

The Federal Bureau of Investigation recently warned American citizens to be extra careful when downloading cryptocurrency and investment apps, as some of them are malicious mobile apps and designed only to steal victim's money.

"The FBI has observed cybercriminals contacting US investors, fraudulently claiming to offer legitimate cryptocurrency investment services, and convincing investors to download fraudulent mobile apps, which the cybercriminals have used with increasing success over time to defraud the investors of their cryptocurrency," the Bureau said. The organization claims criminals have so far defrauded 244 victims out of $42.7 million.

Even though the cryptocurrency world is in a deep bear market (Bitcoin has lost roughly two-thirds of its value since November 2021), cybercriminals are as active as ever. Some of them are using advanced techniques, such as deepfake videos, to trick people into thinking high-profile individuals endorse their projects. Others are stealing identities, creating fake social media accounts of attractive women, asking for “help” or inviting people into co-investing in projects that promise high returns on their investments.

Cryptominers, malware that mines cryptocurrencies, are as popular among cybercriminals as ever before, and tokens are still the number one payment method in ransomware attacks. The FBI urges everyone to be extra careful when downloading apps, to make sure they’re only downloading from legitimate sources (for example, Google’s and Apple’s mobile app repositories), and to have two-factor authentication enabled on all accounts.

Latest Tech News

Google has announced new Play Store policies for Android developers in an effort to crack down on full-screen ads, VPNs, and fake apps impersonating genuine software.

Coming into effect from September 30, 2022, the Play Store will require developers to stop showing “Full-screen interstitial ads,” for example those that show during gameplay or during an app’s loading screen. Additionally, full-screen ads that cannot be closed after 15 seconds shall be banned.

The new policy will not include rewarded ads, such as in-app popups that users can opt into in order to unlock in-app content, which will continue to be permitted.

Google Play Store developer policies

There have been further revisements to the company’s FLAG_SECURE feature, which is intended to protect sensitive data by preventing or obscuring screenshots, and disallowing screen sharing and broadcasting. From November 1, 2022, apps will not be allowed to create workaround for the flagged content.

With effect from the same date, VPNs will also be subject to tighter restrictions. Only dedicated VPN apps will be allowed to “create a secure device-level tunnel to a remote server,” with some exceptions

Access to the USE_EXACT_ALARM permission will also be refined to primarily include only the apps that “requires precisely timed actions” (from July 31, 2022)

Fake Google Play Store apps

Maybe of most interest to general consumers will be a change that is due to be enforced on August 31, 2022.

“We don’t allow apps that mislead users by impersonating someone else (e.g. another developer, company or entity) or another app… To ensure that Google Play remains a safe and respectful platform, we've created standards defining and prohibiting content that is harmful or inappropriate for our users," Google said in a blog post announcing the news.

The company recommends checking the developer name (displayed beneath the app title within the Play Store), that the logo matches the company’s logo, and that the name appears to be genuine and not mis-leading.

Further changes to the company’s app store include eliminating misleading health information, better subscription management, safer child-friendly ads, and further personal protection steps.

Latest Tech News

We often see Roku sale prices falling well below MSRP, all thanks to the particularly competitive world of streaming sticks. Whether you're after a super simple HDMI plugin, or something designed to offer high quality 4K resolution and plenty of smart home features, you'll find all the best Roku deals right here.

Roku's Streaming sticks and boxes plug into your TV via an HDMI port, essentially turning any old HD/4K TV into a smart TV or boosting the number of apps on any modern smart TV that seems to be missing a few of your favorites. In a video streaming device world dominated by Amazon, Google, and Apple, Roku is the plucky underdog that continues to hold its own.

In addition to worldwide services like Netflix, Amazon, and Spotify, you'll find plenty of apps for your country. HBO Now, Hulu, Sling, and CBS All Access in the US and BBC iPlayer, All 4, and Now TV in the UK, for example. Frankly, Roku can't be beaten as far as the number and quality of streaming services it supports. And yes, there are options to view in 4K HDR too.

There are a lot of Roku devices out there in the wild, though, and some of them have been discontinued as they've been made obsolete by newer releases. Some, however, have an advantage or feature that new sticks don't cater for, so we've kept price comparison charts around for those models. 

Generally, though, we've cut down the list to include the most relevant Roku streaming devices that are readily available and represent great value of money for you.

Roku Express 4K

Roku Express 4K Plus 2021

Roku's latest 4K HDR streaming device

Picture quality: HD, 4K, HDR10+ | Connectivity: Wireless | Remote: Voice with TV power and volume controls | Headphone jack: No | Storage expansion: N/A

Affordable
4K HDR (and HDR10+) streaming
Voice remote

The Roku Express 4K Plus was released in April of this year and allows you to stream your favorite content in 4K Ultra HD resolution with support for HDR10+. The affordable streaming stick includes a Roku voice remote so you can launch movies, search for titles and adjust the volume completely hands-free.

The 4K streaming device launched in the US and UK with a starting price of $39.99/£39.99. Even though the Roku Express 4K is a new release, we've already seen slight discounts on the streaming device, and we're hoping to see a record-low price during the upcoming Black Friday 2021 sale.

Roku Express deals

The best entry-level Roku streamer

Picture quality: 1080p HD | Connectivity: Wireless | Remote: Standard | Headphone jack: No | Storage expansion: N/A

Dirt cheap
Faster than the old cheap models
No 4K Streaming

This is the cheapest streaming device in the Roku family. The Roku Express is newer and cheaper than the other standard Roku Streaming Stick and does all the same jobs. If you want to turn any HDMI TV into a Smart TV for as little as possible - this is for you. 

However, we'd be tempted to keep an eye out for a good deal on the 4K version mentioned earlier just to avoid having to buy one once 4K content becomes the norm.

Roku Streaming Stick Plus deals

A tiny yet superb 4K streaming device

Picture quality: 1080p HD, 4K, HDR | Connectivity: Wireless | Remote: Voice with TV power and volume controls | Headphone jack: No | Storage expansion: N/A

Cheap 4K Streaming
Improved remote
Packed with apps

Roku continues to give rival streaming devices something to worry about as the new Roku Streaming Stick Plus is super modern, super small and, most importantly, super cheap. Not to mention, unlike many of the older models it's been released in the UK too. Now Brits can finally join the 4K Roku party like the US has been enjoying for years! You're even getting HDR content from supported apps too.

While Amazon's 4K Fire TV Sticks are similarly priced and have a more intuitive remote design, plus Alexa support, you might find the wider range of streaming services on the Roku more appealing.

Roku Ultra deals

The one with all the features

Picture quality: 1080p HD, 4K, HDR | Connectivity: Wireless or ethernet | Remote: Voice with TV power, volume and gaming controls | Headphone jack: Yes - on remote and box | Storage expansion: Micro SD and USB

Headphone jack on remote
Expandable storage
Gaming remote
More expensive

This Roku was not released in the UK. So don't expect many (if any) UK prices. The Roku Ultra is the most feature-packed of all the Roku media streamers. It has all the quality 4K and HDR streaming and ports of the Roku Premiere Plus. So what do you get for the extra cash? The remote control gets the most attention on the Ultra as it can be used for voice search, it has extra buttons to make it a handy game controller and there's even a little speaker to help you find it via a button on the console. There's also a USB storage slot and an optical out audio port.  We're loving the option for private listening via the bundled-in JBL headphones headphones that you can plug into the remote too. 

If you're not bothered about the extra audio ports, expandable storage and using the Roku for gaming, then you should opt for one of the Roku deals we mentioned earlier and save a big chunk of cash.
