Scientists Take First Snapshots of Ultrafast Switching in a Quantum Electronic Device

They discover a short-lived state that could lead to faster and more energy-efficient computing devices.

 Electronic circuits that compute and store information contain millions of tiny switches that control the flow of electric current. A deeper understanding of how these tiny switches work could help researchers push the frontiers of modern computing.

Now scientists have made the first snapshots of atoms moving inside one of those switches as it turns on and off. Among other things, they discovered a short-lived state within the switch that might someday be exploited for faster and more energy-efficient computing devices.

The research team from the Department of Energy’s SLAC National Accelerator Laboratory, Stanford University, Hewlett Packard Labs, Penn State University and Purdue University described their work in a paper published in Science today (July 15, 2021).

“This research is a breakthrough in ultrafast technology and science,” says SLAC scientist and collaborator Xijie Wang. “It marks the first time that researchers used ultrafast electron diffraction, which can detect tiny atomic movements in a material by scattering a powerful beam of electrons off a sample, to observe an electronic device as it operates.”

The team used electrical pulses, shown here in blue, to turn their custom-made switches on and off several times. They timed these electrical pulses to arrive just before the electron pulses produced by SLAC’s ultrafast electron diffraction source MeV-UED, which captured the atomic motions happening inside these switches as they turned on and off.

Capturing the cycle

For this experiment, the team custom-designed miniature electronic switches made of vanadium dioxide, a prototypical quantum material whose ability to change back and forth between insulating and electrically conducting states near room temperature could be harnessed as a switch for future computing. The material also has applications in brain-inspired computing because of its ability to create electronic pulses that mimic the neural impulses fired in the human brain.

The researchers used electrical pulses to toggle these switches back and forth between the insulating and conducting states while taking snapshots that showed subtle changes in the arrangement of their atoms over billionths of a second. Those snapshots, taken with SLAC’s ultrafast electron diffraction camera, MeV-UED, were strung together to create a molecular movie of the atomic motions.

“This ultrafast camera can actually look inside a material and take snapshots of how its atoms move in response to a sharp pulse of electrical excitation,” said collaborator Aaron Lindenberg, an investigator with the Stanford Institute for Materials and Energy Sciences (SIMES) at SLAC and a professor in the Department of Materials Science and Engineering at Stanford University. “At the same time, it also measures how the electronic properties of that material change over time.”

With this camera, the team discovered a new, intermediate state within the material. It is created when the material responds to an electric pulse by switching from the insulating to the conducting state.

“The insulating and conducting states have slightly different atomic arrangements, and it usually takes energy to go from one to the other,” said SLAC scientist and collaborator Xiaozhe Shen. “But when the transition takes place through this intermediate state, the switch can take place without any changes to the atomic arrangement.”

Opening a window on atomic motion

Although the intermediate state exists for only a few millionths of a second, it is stabilized by defects in the material.

To follow up on this research, the team is investigating how to engineer these defects in materials to make this new state more stable and longer lasting. This will allow them to make devices in which electronic switching can occur without any atomic motion, which would operate faster and require less energy.

“The results demonstrate the robustness of the electrical switching over millions of cycles and identify possible limits to the switching speeds of such devices,” said collaborator Shriram Ramanathan, a professor at Purdue. “The research provides invaluable data on microscopic phenomena that occur during device operations, which is crucial for designing circuit models in the future.”

The research also offers a new way of synthesizing materials that do not exist under natural conditions, allowing scientists to observe them on ultrafast timescales and then potentially tune their properties.

“This method gives us a new way of watching devices as they function, opening a window to look at how the atoms move,” said lead author and SIMES researcher Aditya Sood. “It is exciting to bring together ideas from the traditionally distinct fields of electrical engineering and ultrafast science. Our approach will enable the creation of next-generation electronic devices that can meet the world’s growing needs for data-intensive, intelligent computing.”

MeV-UED is an instrument of the LCLS user facility, operated by SLAC on behalf of the DOE Office of Science, who funded this research.

SLAC is a vibrant multiprogram laboratory that explores how the universe works at the biggest, smallest and fastest scales and invents powerful tools used by scientists around the globe.

Windows 10 users could pay a monthly fee to unlock Windows 11 on all of their devices

Microsoft is poised to offer a completely new way to get Windows running on your PC. Dubbed Windows 365, the Redmond-based company will begin allowing commercial customers the chance to subscribe for remote access to Windows 10, with an upgrade to Windows 11 as soon as it becomes available. Named after its hugely-successful Office 365 subscription, which lets users access applications like Word, Excel, Outlook across a multisite of devices for as long as they pay the monthly fee, Windows 365 will operate in a similar way.

So, rather than paying a set fee to download Windows 11, you’ll pay a smaller cost each month to gain access to the operating system. To begin, this scheme will only be available to commercial customers. Businesses will charged per user per month, rather than paying for each new installation of Windows on the company PCs, laptops and tablets handed out to employees.

“Windows 365 is a cloud service that introduces a new way to experience Windows 10 or Windows 11 for workers from interns and contractors to software developers and industrial designers,” Microsoft 365 general manager Wangui McKelvey explains.

“Windows 365 takes the operating system to the Microsoft Cloud, securely streaming the full Windows experience—including all your apps, data, and settings—to your personal or corporate devices. This approach creates a fully new personal computing category, specifically for the hybrid world: the Cloud PC.” 

Following the launch of Windows 10, which Microsoft heralded at the time as the “last version of Windows”, many assumed the immensely-popular operating system would move to a subscription model. Software giant Adobe has enjoyed huge success with its Creative Cloud subscription – as has Microsoft with its Office 365 option for enterprise and consumers.

As well as the lack of individual software licenses for each device, there are some other advantages to Windows 365 over the traditional approach.

According to Microsoft, since the computers in its server farm are doing most of the heavy lifting, Windows 365 will provide an “instant-on boot experience”. Not only that, but it works with virtually all devices, including Macs, iPads, Linux PCs, and Android tablets and smartphones.

Microsoft will remember the last state of the operating system too, so that each time you sign in – you’ll pick up exactly where you left off. That’s true regardless of whether you’re logging back into the same machine, or picking up a new one. The ability to move from desktop PC in the office, to laptop on the train home – and have the same documents, files, and half-drafted email open and ready to go is sure to be a hit with users.

Windows 365 will be available to companies of all sizes from August 2, 2021. Unfortunately, there’s no word on pricing quite yet.

Is your Android phone flawed? Millions sold devices that could put them at serious risk

Android smartphone owners are being warned that their new devices may put them at serious risk from cyber attacks and malicious threats. That’s the latest news from the consumer experts at Which? who say devices are being sold on long-term contracts that will no longer get vital updates to keep them safe. Most Android manufacturers offer two or three years of Android upgrades but networks are selling phones that may not get these vital patches by the time a customer’s deal comes to an end.

The problem is so bad that Which? says around 48 per cent of phones available could lose security support before the end of the contract period.

O2 is one of the networks that caused the most concern as it offers deals that last for 36 months.

However, it’s not just O2 with other mobile phone retailers also selling a whole host of devices that could lose security support before contracts ended. In addition to O2, the proportion of contract phones on sale where there were similar problems were Carphone Warehouse (52%), Mobiles.co.uk (50%), Vodafone (50%), Three (40%), Mobile Phones Direct (38%) and EE (33%).

To make matters worse, Which? researchers say that they came across a number of popular handsets that are due to run out of support less than a year into the contract.

These included the Motorola G8 Power (sold by mobiles.co.uk and Vodafone), Oppo Find X2 Lite (sold by EE, Mobile Phones Direct, mobiles.co.uk, O2 and Vodafone) and Samsung’s Galaxy S9 (sold by Vodafone).

Although the lack of long-term updates on Android is nothing new, Which? says that it’s the lack of transparency from networks that’s most concerning.

Four in 10 (40%) smartphone owners think that if they buy a phone on contract it will receive security updates throughout the contract period.

In response to the report, EE and Three said they disputed some of the mobile phone models included in the analysis, stating that these phones would be supported until the end of contracts.

Vodafone added that “support generally extends beyond the timeframe you reference.” However, Which? believes these phones could be out of support before the end of contracts, according to its research.

It’s clearly worrying as, once security updates are no longer pushed out, phones become easy targets for hackers who can use malicious software to take over devices and even install apps that subscribe owners to premium services without their permission.

Speaking about the report Kate Bevan, Which? Computing Editor, said: “Mobile phones without the latest security support could leave consumers vulnerable to hackers, so it is important that manufacturers supply these defences for longer and that retailers are clearer with people about the risks posed by phones that will not receive vital updates for the duration of contracts.

“The government’s Product Security Bill needs to ensure that manufacturers state the date a device will be supported until – and that this information is clearly displayed on retailers’ websites. Devices need to be supported for five years minimum across all manufacturers so that consumers are better protected.”

Fire TV streaming devices drop to lowest EVER price in Amazon Prime Day bargains

Looking for something new to watch? Amazon has slashed the price of two of its best Fire TV streaming gadgets in its annual Prime Day sale – so you can stream shows from Prime Video, Netflix, BBC iPlayer, Shudder, Apple TV+, BritBox, and Sky thanks to its NOW on-demand service. These discounts only last until tomorrow evening, when the annual Prime Day sales come to a close.

First up, Amazon Fire TV Stick 4K with Alexa Voice Remote has been slashed from £49.99 down to £26.99. That’s a saving of £23 – almost half price compared to the usual price tag. As well as streaming in crisp Ultra HD, the streaming gadget, which plugs into the HDMI port on your telly, also comes with a voice-controlled remote.

This leverages chatty AI assistant Alexa to find shows and movies with your voice, lets you search for favourite actors and directors. Since it’s the same Alexa assistant that powers the Amazon Echo, you can use it to control any smart lightbulbs in your home, answer video doorbells, request songs to play on smart speakers and more.

If you want the best of the best, Amazon’s flagship Fire TV Cube is also included in the Prime Day sale. This clever telly gadget is essentially a combination of an Amazon Echo Dot and a Fire TV 4K Stick into a single set-top box. As you’d expect, Fire TV Cube bundles all of your favourite streaming services, BBC iPlayer, Prime Video, ITV Hub, YouTube, All 4, NOW, Disney+, Netflix, and more. But it also lets you use Alexa to control your television hands-free.

So, you can recline on your sofa and bark at Alexa to change channels, switch between HDMI inputs, adjust the volume, and more.

Usually priced at £109.99, the Fire TV Cube is currently £59.99 – a saving of £50. If you’re looking to seriously step-up your streaming game, this is the Fire TV device to buy.

Of course, as always with the annual Prime Day sales, you’ll need to have a Prime membership to buy any of these discounted goodies. Thankfully, you won’t have to pay the £79 annual membership fee today, instead, Express.co.uk has a simple way of getting the discounts without paying Amazon for the subscription service. You’ll need to sign-up for a 30-day trial, place your order, and then cancel the Prime membership after your order arrives in the mail.

Amazon lets you cancel the Prime trial at any point during the 30-days without incurring any costs at all. If you do decide to keep your Prime membership, you’ll get next-day (or sometimes same day) shipping on items handled by Amazon, free Kindle books, movie and boxset streaming via Prime Video, unlimited photo back-up, and more.

Buyers of Amazon Devices Are Guinea Pigs. That’s a Problem.

After a few years of testing prototypes and forming partnerships to procure artwork, the collaboration resulted in the 2017 introduction of the Frame TV, a Samsung television that resembled a picture frame. It used motion sensors to show art when people were present and shut off when nobody was around. The TV has become a best seller.

Mr. Béhar, who founded Fuseproject, an industrial design firm, said he understood Amazon’s approach as a retail company to rapidly test ideas — like when it measures how customers respond to different prices in its stores. But “with hardware, people end up being left with stuff that’s useless or doesn’t work anymore,” he said. “In the world that we live in today, with global warming and plastics and waste, I do think it’s something to be very careful about.”

Don Norman, who founded the Design Lab at the University of California, San Diego, and wrote the book “The Design of Everyday Things,” said that throughout his career, he had seen some other companies use approaches similar to Amazon’s.

In the 1990s, when Mr. Norman worked with Apple as a user experience architect, the company collaborated with Sony on a product. He said Apple had planned to spend years doing market research and testing prototypes before shipping it.

“Sony laughed at us and said: ‘What a stupid way of doing things. We just build a product, and we sell it. We get the feedback, and we kill it and do a better one. It’s much more efficient and faster than your method,’” Mr. Norman said.

This on-the-fly approach to development is unpopular, he said, because most companies recognize that customers get angry when gadgets are quickly killed. “There’s some logic to it but also a complete disrespect to what it might mean to your customers or environment or the world,” Mr. Norman said.

Kyle Wiens, the chief executive of iFixit, a company that sells parts for people to repair gadgets, said there were better ways than Amazon’s to discontinue products. When Pebble, a smartwatch maker, shut down in 2016, the company said the software would continue to work. People continued to enjoy the product years after the company’s death.

Microsoft is bringing Xbox Game Pass to TVs and launching new streaming devices

June will see Xbox host a big E3 event, complete with new game news and announcements.

But before that gets underway, Microsoft has revealed that it has big plans for its popular subscription, the Xbox Game Pass.

Available on PC, Xbox One and Xbox Series X, the XGP makes it possible to access a library of games at a fixed monthly price.

It removes the need to buy games, and makes it possible to play first-party Microsoft games at launch.

The new service has proven very popular with fans and that probably explains why the tech giant wants to bring it to more platforms.

As revealed today in a pre-E3 announcement, Microsoft is planning on launching Xbox Game Pass services onto TV and streaming devices.

It’s part of an aggressive expansion programme that will see the Xbox Game Pass launched on multiple platforms without the need for hardware.

Microsoft has solved this issue by making it possible to stream games using xCloud, something that is currently available on Android phones.

But by removing the need for hardware, the company hopes to expand into a much wider market.

It was revealed today that Xbox is working with global TV manufacturers to embed the Xbox experience directly into internet-connected televisions with no extra hardware required except a controller.

Those partners have not been revealed yet, and it’s hard to say at this point how much such a service would cost.

But that might fit in with another announcement made today by Microsoft; that Xbox is exploring new subscription offerings for Xbox Game Pass so more players around the world can use it.

It would make sense that Microsoft would provide a cheaper alternative for Xbox Game Pass which would appeal to the casual market.

And with the removal of hardware and easier access through TVs, Xbox Game Pass could become a useful tool.

While Xbox Game Pass is coming to TVs, Microsoft has also announced that they are preparing other projects for the market.

This includes Xbox building its own streaming devices for cloud gaming to reach gamers on any TV or monitor without the need for a console.

Stating its intent to shake things up, Microsoft revealed today: “We believe that games, that interactive entertainment, aren’t really about hardware and software.

“It’s not about pixels. It’s about people. Games bring people together,” said Spencer. “Games build bridges and forge bonds, generating mutual empathy among people all over the world. Joy and community – that’s why we’re here.”

“Gaming is fundamentally aligned with our mission as a company.

“When you talk about Xbox’s mission to bring the joy and community of gaming to everyone on the planet, which I absolutely love, that is precisely aligned with Microsoft’s mission, which is to empower every person and every organization on the planet to achieve more.”

It’s hard to say whether these new projects will prove to be successful for Microsoft as they look to adapt to a changing market.

It will be a challenge to overtake Sony’s PS5 in the hardware stakes, so conquering the casual market could prove incredibly profitable.

Microsoft is hoping that its Xbox App for TVs will help more people play games but it’s hard to say just how palpable it will be, as an Xbox controller will still be required.

SAFE-PAD: Paclitaxel Devices Exonerated in Real-World Data

A cohort analysis using advanced strategies to minimize the impact of confounders has concluded that the current Food and Drug Administration warning about paclitaxel-coated devices used for femoropopliteal endovascular treatment should be lifted, according to investigators of a study called SAFE-PAD.

In early 2019, an FDA letter to clinicians warned that endovascular stents and balloons coated with paclitaxel might increase mortality, recounted the principal investigator of SAFE-PAD, Eric A. Secemsky, MD, director of vascular intervention, Beth Israel Deaconess Hospital, Boston.

An FDA advisory committee that was subsequently convened in 2019 did not elect to remove these devices from the market, but it did call for restrictions and for the collection of more safety data. In the absence of a clear mechanism of risk, and in the context of perceived problems with data suggesting harm, Secemsky said that there was interest in a conclusive answer.

The problem was that a randomized controlled trial, even if funding were available, was considered impractical, he noted in presenting SAFE-PAD at the annual scientific sessions of the American College of Cardiology.

In the initial meta-analysis that suggested an increased mortality risk, no risk was seen in the first year after exposure, and it climbed to only 3.5% after 2 years. As a result, the definitive 2-year study with sufficient power to produce conclusive results was an estimated 40,000 patients. Even if extended to 5 years, 20,000 patients would be needed, according to Secemsky.

SAFE-PAD Born of Collaboration

An alternative solution was required, which is why “we became engaged with the FDA to design a real-world study for use in making a regulatory decision,” Secemsky said.

SAFE-PAD, designed with feedback from the FDA, employed sophisticated methodologies to account for known and unknown confounding in the Medicare cohort data used for this study.

Of 168,553 Medicare fee-for-service patients undergoing femoropopliteal artery revascularization with a stent, a balloon, or both at 2,978 institutions, 70,584 (42%) were treated with a paclitaxel drug-coated device (DCD) and the remainder were managed with a non–drug-coated device (NDCD).

The groups were compared with a primary outcome of all-cause mortality in a design to evaluate DCD for noninferiority. Several secondary outcomes, such as repeated lower extremity revascularization, were also evaluated.

To create balanced groups, inverse probability of treatment weighting (IPTW) blinded to outcome was the primary analytic strategy. In addition, several sensitivity analyses were applied, including a technique that tests for the impact of a hypothetical variable that allows adjustment for an unknown confounder.

After a median follow-up of 2.7 years (longest more than 5 years), the cumulative mortality after weighting was 53.8% in the DCD group and 55.1% in the NDCD group. The 5% advantage for the DCD group (hazard ratio, 0.95; 95% confidence interval, 0.94-0.97) ensured noninferiority (P < .001).

On unweighted analysis, the mortality difference favoring DCD was even greater (HR, 0.85; 95% CI, 0.82–0.85).

None of the sensitivity analyses — including a multivariable Cox regression analysis, an instrumental variable analysis, and a falsification endpoints analysis that employed myocardial infarction, pneumonia, and heart failure — altered the conclusion. The hypothetical variable analysis produced the same result.

“A missing confounder would need to be more prevalent and more strongly associated to outcome than any measured variable in this analysis,” reported Secemsky, indicating that this ruled out essentially any probability of this occurring.

A subgroup analysis told the same story. By hazard ratio for the outcome of mortality, DCD was consistently favored over NDCD for groups characterized by low risk (HR, 0.98), stent implantation (HR, 0.97), receipt of balloon angioplasty alone (HR, 0.94), having critical limb ischemia (HR, 0.95) or no critical limb ischemia (HR, 0.97), and being managed inpatient (HR, 0.97) or outpatient (HR, 0.95).

The results of SAFE-PAD were simultaneously published with Secemsky’s ACC presentation.

Value of Revascularization Questioned

In an accompanying editorial, the coauthors Rita F. Redberg, MD, of the University of California, San Francisco, and Mary M. McDermott, MD, of Northwestern University, Chicago, reiterated the findings and the conclusions, but used the forum to draw attention to the low survival rates.

“Thus, while this well-done observational study provides new information,” they wrote, “a major conclusion should be that mortality is high among Medicare beneficiaries undergoing revascularization [for peripheral artery disease] with any devices.”

“Very impressive” Methods

Marc P. Bonaca, MD, director of vascular research, University of Colorado at Denver, Aurora, called the methods to ensure the validity of the conclusions of this study “very impressive.” In situations where prospective randomized trials are impractical, he suggested that this type of approach might answer an unmet need.

“We have always desired the ability to look at these large datasets with a lot of power to answer important questions,” he said. While “the issue has always been residual confounding,” he expressed interest in further verifications that this type of methodology can serve as a template for data analysis to guide other regulatory decisions.

Secemsky reports financial relationships with Abbott, Bayer, Boston Scientific, Cook, CSI, Inari, Janssen, Medtronic, and Phillips. Redford reports no potential conflicts of interest. McDermott reports a financial relationship with Regeneron. Bonaca reports financial relationships with Amgen, AstraZeneca, Bayer, Janssen Merck, Novo Nordisk, Pfizer, and Sanofi.

Hillicon Valley: House lawmakers fired up for hearing with tech CEOs

Today: The CEOs of major social media platforms are gearing up to testify before a House committee tomorrow on misinformation around COVID-19 and the recent Capitol riot. Meanwhile, a group of 12 state attorneys general are pressuring Facebook and Twitter to tackle COVID-19 vaccine misinformation, and two lawmakers reintroduced legislation aimed at making internet-connected devices safer for the consumer.


TECH HEARING TIME AGAIN: The CEOs of the country’s biggest social media platforms will testify Thursday before a Congress eager to press them on their roles spreading misinformation related to coronavirus and the lead-up to the deadly insurrection at the Capitol in January.

We want them to understand how seriously they better take this.”

What to expect: The hearing will likely focus on the part the massive platforms play in spreading potentially dangerous misinformation — ranging from election result conspiracies to lies about the coronavirus vaccine — and a suite of proposed and forthcoming legislative fixes to Section 230 of the Communications Decency Act, which gives platforms liability protection from content posted by third parties and allows them to safely moderate.

All three companies have highlighted their work on content moderation and new policies recently, hinting at how they will approach the hearing.

HERE’S WHAT THE CEOS WILL SAY: Facebook CEO Mark Zuckerberg is set to propose a reform to legal liability protections for tech firms during congressional testimony on Thursday.


In prepared remarks released Wednesday, Zuckerberg argues that the immunity granted by Section 230 of the Communications Decency Act for third-party posts should be conditioned on platforms adhering to best practices for removing unlawful content.

“Instead of being granted immunity, platforms should be required to demonstrate that they have systems in place for identifying unlawful content and removing it,” he is set to tell the House Energy and Commerce Committee.

Google’s plans: Pichai’s testimony appears to hew to a more cautious approach to Section 230, warning that repealing it could hamper efforts to address misinformation.

Twitter’s input: Dorsey’s prepared remarks focus less on legislative fixes and more on the content and policy decisions that Twitter has made recently to rein in misinformation.

STATE AGS ON THEIR CASE: A group of 12 state attorneys general sent a letter to Facebook and Twitter on Wednesday urging them to more aggressively enforce platform policies against coronavirus vaccine misinformation.

Led by Connecticut Attorney General William Tong (D), the group argues that content on the social media sites are increasing vaccine hesitancy, which will “slow economic recovery and, more importantly, ultimately cause even more unnecessary deaths.”

Bad data: The letter points to a report released by the Center for Countering Digital Hate Wednesday that claims that anti-vaccine accounts on Facebook, Twitter, Instagram and Youtube have more than 59 million followers.

The study also found that the personal accounts and associated organizations of 12 prominent figures account for upward of 60 percent of anti-vaccine content on Facebook, Twitter and Instagram, which is owned by Facebook.

“Social media is enabling anti-vaxxers to recruit millions of Americans and indoctrinate them with fear and doubt,” Imran Ahmed, CEO of the center, said in a statement on the report’s release. “If Big Tech companies don’t act now, the pandemic will be prolonged, and more lives will be lost.”

Stamp of approval: The bill would also establish an advisory committee made up of cybersecurity experts in government, the private sector and academia to create security benchmarks for internet-connected devices. The benchmarks would enable the devices’ manufacturers to voluntarily label their products to show they have met these standards.


Markey and Lieu previously introduced the legislation in both the House and Senate in 2019, but it never got a vote in either chamber. [40]
