Qualcomm’s Snapdragon Elite chips have been the star of many AI PCs released to market in 2024, greatly enhancing performance and battery life compared to their previous gen iterations. However, the manufacturer’s recent endeavor to improve on one of its negative points hasn’t panned out.

Qualcomm has canceled its dev kit, a Snapdragon mini-PC powered by Windows on Arms. Originally, it was planned for a June 2024 release window but missed that entirely. Now, as part of an official announcement, Qualcomm has stated that the kit has been canceled because it “has not met our usual standards of excellence.”

Interestingly enough, The Verge spotted that multiple developers had already received the mini-PC including YouTuber Jeff Geerling, who reviewed the product and performed a detailed hardware teardown of it. Despite Qualcomm not providing any specific reasons for why the PCs had been canceled, the conclusions from Geerling’s review are that despite it matching the Apple M3 Pro’s performance, it lacks Linux support and had restrictions around reselling the device.

There’s another theory for the cancellation as well, which comes down to the HDMI port — or lack thereof. Though the shipped mini-PCs all came with the chips for internal DisplayPort to HDMI conversion, the actual port was missing for some reason.

According to Richard Campbell, founder of DEVIntersection, the HDMI port could have been the cause of the massive delays if it failed FCC compliance testing. This seems to be supported by the fact that Qualcomm emailed anyone who ordered the PC in September that they would be sent a USB-C to HDMI dongle with their dev kit.

But what does this mean for the consumer?

One of the most well-known drawbacks to anything Qualcomm is that Windows on Arms still has compatibility issues with some Windows programs, tools, and apps. The manufacturer has improved this by leaps and bounds to the point that the average user wouldn’t know the difference, but for gamers and others using specialized programs, those compatibility problems can be quite difficult to parse.

In comes the Qualcomm mini-PC dev kit, which would have been the perfect tool for developers to port their apps to Windows on Arms. This potentially could have introduced a large amount of apps to the OS that otherwise would have never seen the light of day on Arm chips. This is especially important for the consumers who have been left in the dark due to the lack of app support for tools that they need themselves, limiting Qualcomm’s sales of its AI PCs to them in turn.

And with fellow industry rivals Intel and AMD teaming up to form the “x86 Ecosystem Advisory Group,” in response to Qualcomm and other competitors, the latter must figure out either how to fix the issues with the dev kits or figure out another way to resolve these app compatibility issues if it wants to see Arms continue to thrive.

Ferrari has lifted the lid on the most powerful road-going supercar it has ever built, cramming the carbon fibre-laden F80 with a three-liter twin-turbo six cylinder engine that develops 900hp on its own.

The combustion engine is then paired up with three electric motors (all developed in house) that throw an additional 300hp into the mix. That’s 1200 horses in total from a propulsion system that is essentially derived from its 499P Le Mans race car, but is equally as happy popping to the shops for a pint of milk.

Far from an attempt to reduce Ferrari’s overall carbon emissions, this is instead an exercise in extracting maximum performance. The diminutive 800V/2.3kWh battery that is stashed behind the seats, for example, uses F1 technology to ensure it can charge and discharge in the quickest and most efficient way possible.

That means customers won’t be able to drive the F80 in an all-electric mode, but will instead be able to rocket from a standstill to 62mph in 2.15 seconds, reach 124mph in just 5.75 seconds and max out at 217mph. Mind-melting stuff.

The F80 is engineered for raw performance, using a carbon-fiber chassis that is as narrow as engineers could get away with to ensure less aerodynamic drag. Inside, there’s just about enough room for the driver and one very small passenger.

Ferrari calls it a "1+" vehicle, seeing as the second seat is slightly staggered to allow the controls to envelope the driver. To highlight that this isn't some romantic grand tourer, the driver’s seat is bright red, while the poor passenger has to make do with black... and race harnesses.

There’s so much tech trickery going on underneath the spaceship-style body and butterfly wing doors that engineers from Maranello could easily fill an entire Netflix documentary series with content. The motor-controlled active suspension system, for example, negates the need for anti-roll bars and allows the vehicle to transform from hunkered down track monster to a pliant road ride with ease.

Ferrari has harnessed 3D printing technology to create the suspension wishbones, and also used copious amounts of carbon fiber for its five-spoke alloys wheels and has also introduced some serious software trickery to squeeze the most out of race circuit lap times.

Boost Optimization, which race fans can access in the two high performance driving modes (Performance and Qualify), maps warm-up laps of a favored circuit and then automatically delivers additional horsepower in the section that it deems need it most, such as when accelerating along a straight.

A technological powerhouse

The Ferrari F80 won’t actually go into production until 2025 – from then, the 799 lucky customers that are selected to receive one will have to wait until 2027 to experience it. Handily that's Ferrari’s 80th anniversary, hence the name.

It will cost around €3.6million, which is over $4million and almost AU$6million, by far the most expensive Ferrari road car ever built and up there with some of most expensive production super cars of all time.

But it moves the game on for the Italian automaker, not just in the raw figures when compared to the LaFerrari it usurps but also in the active aerodynamic technology, track-focussed features and extensive use of e-motors in everything from the turbochargers to the suspension system.

The proof is in the pudding, as the marque claims the F80 posted a new lap record of its Fiorano test track of 1min 15.3secs – that’s 4.4 seconds faster than the LaFerrari.

This might sound like marginal gains, but the numbers are huge in the cutthroat world of low-volume but hideously expensive super cars.

The Sun’s corona, its outermost atmospheric layer, holds the key to understanding solar activity, including phenomena like solar flares and space weather events. For decades, scientists have grappled with the challenge of measuring the Sun’s coronal magnetic field, as this field drives much of the energy that leads to solar eruptions.

Now, in a groundbreaking achievement, Professor Tian Hui's research team from Peking University, in collaboration with international experts, has made the first conventional measurements of the global coronal magnetic field. Their findings, published in the journal Science (Volume 386, No 6717), offer new insights into the Sun’s magnetic activity over a period of eight months.

The Sun’s magnetic field is responsible for storing and releasing energy, which heats the plasma in the corona and triggers solar eruptions. These eruptions, in turn, can have significant impacts on space weather, potentially affecting satellite operations, GPS systems, and even human spaceflight. However, due to the relatively weak nature of the coronal magnetic field compared to the magnetic field on the Sun’s surface (the photosphere), measuring this field has proven to be a significant challenge.

The importance of coronal magnetic field measurements

As the Sun rotates, there are variations in the magnetic fields and the ability to regularly monitor the Sun’s coronal magnetic field will improve our understanding of solar eruptions and help protect high-tech systems on Earth and in space.

Over the years, there have been routine measurements of the photospheric magnetic field, but the coronal field has remained elusive. This limitation has impeded scientists' ability to fully understand the three-dimensional magnetic field structure and the dynamic processes that occur in the Sun’s atmosphere.

In 2020, Tian Hui's team developed a method called “two-dimensional coronal shocks,” which enabled the first measurements of the global distribution of the coronal magnetic field. This was a major milestone, marking a crucial step towards the goal of routine coronal magnetic field measurements.

More recently, Tian's team refined this method further, allowing them to track magnetohydrodynamic shear waves in the corona with greater precision. This made it possible to diagnose the distribution of coronal density and, as a result, determine both the strength and direction of the magnetic field.

Using the Upgraded Coronal Multi-Channel Polarimeter (UCoMP), the research team conducted detailed observations of the Sun’s corona from February to October 2022. Over this eight-month period, they collected 114 magnetograms, or magnetic field images, which allowed them to observe the evolution of the coronal magnetic field at different altitudes and latitudes across multiple solar rotations. The magnetic field strength measured between 1.05 and 1.60 solar radii and varied from less than 1 gauss to around 20 gauss.

With these measurements, they were able to create a global map of the magnetic field intensity in the Sun’s corona. This map revealed how the magnetic field evolves over time and across different regions of the Sun.

When compared to the predictions of the most advanced global coronal models—such as the one developed by Predictive Science, a U.S.-based company—the team found that their observational data closely matched the model’s predictions in mid- and low-latitude regions. However, they noted larger discrepancies in high-latitude regions and active areas of the Sun.

These findings are critical for improving current models of the Sun’s magnetic activity and understanding the dynamics of solar eruptions. As lead author Yang Zihao explains, the team's observations provide a key foundation for refining and optimizing coronal models, which could eventually lead to more accurate predictions of solar eruptions and their potential impact on Earth’s space environment.

This study marks a shift in solar physics, as the field enters a new era of routine coronal magnetic field measurements.

According to Tian Hui, this achievement is just the beginning. While their current methods allow for the measurement of the magnetic field at the edge of the solar disk, the next goal is to develop techniques that will enable a complete measurement of the entire coronal magnetic field, including the solar disk itself. This will require the integration of other measurement methods and tools, but it represents a critical objective for the solar physics community in the coming decades.

Hot on the heels of China’s accusations that Volt Typhoon is actually a CIA asset, a group of cybersecurity experts from the Cyber Security Association of China (CSAC) have now claimed Intel products sold in China contain “frequent vulnerabilities and high failure rates.”

CSAC also said Intel products present “serious risks to national security,” alleging the US semiconductor manufacturers installed an NSA backdoor “in almost all” of its central processing units (CPU) since 2008 to create a “next-generation security defense system.”

“This poses a huge security threat to the critical information infrastructure of countries around the world, including China,” CSAC said as part of its accusations on the organization’s WeChat account.

Push to open investigation

The US and China have frequently thrown similar allegations at each other, with US lawmakers recently pushing for greater restrictions to be placed on suppliers passing US advanced chip manufacturing equipment on to Huawei, which the US placed on its entity list in 2019, restricting businesses from trading with the Shenzhen headquartered technology company.

China has also been accused of infiltrating US critical infrastructure to establish a list of targets to strike in the event that war breaks out between the two superpowers. UK government ministers also stated this week Chinese state sponsored threat actors may already have access to UK critical infrastructure.

In a statement posted to WeChat, Intel’s China unit said, “We will maintain communication with the relevant authorities, clarify any concerns, and reaffirm our commitment to product safety and quality” (Via Reuters).

CSAC has also requested the Cyberspace Administration of China launch an investigation into Intel products sold in China for vulnerabilities and backdoors “to effectively safeguard China's national security.”

Stress, cyberthreats and overworking are making cybersecurity professionals want to quit in droves, new research has claimed.

The findings from BlackFrog reveal almost a quarter (24%) of security heads are actively seeking a change of job, with over half (54%) not yet at the quitting point, but open to new opportunities.

Overwhelmingly, stress and demands are the main considerations for security pros looking to quit, with 93% stating these as the main cause of their decision to potentially leave.

Burnout reaching new highs

The report also found CISOs and IT security decision makers are also working overtime in an attempt to keep their business secure, with almost every respondent (98%) stating they work more than their contracted hours.

Of those exceeding their hours, 15% are working more than 16 hours of additional time per week in an attempt to defend against almost constant ransomware and malware attacks. The average security pro was found to put in just over an extra day (9 hours) of work per week.

The reasons given for increased stress mirror the changing threat landscape faced by security professionals, with 42% of respondents voicing their concern about the potential for threat actors to integrate AI tools into their attack vectors, with a quarter of respondents also citing data exfiltration as a top concern. 37% stated the threat of ransomware and malware attacks are a significant source of stress.

When it comes to managing stress, there are some positives. Sport and physical activity is recognized as a means of dealing with stress and complementing overall health, with 86% stating that they allocate time to activities. Sleep, on the other hand, is harder to come by, with only three quarters (75%) stating that they get enough shut-eye.

Despite working significant amounts of overtime, 82% of those surveyed said that they set a clear boundary between their work and private life. The downside however is just under half (45%) have used drugs or alcohol as a way to deal with the pressures of the job, and 69% said that they have been more unsociable.

Help is being offered from the upper management of businesses, with many being offered practical support for dealing with the stress of the job, including flexible hours (64%) and hybrid or remote working for their role (62%).

But security heads still believe that there's more to be done to manage their stress and keep them from quitting, with bigger budgets for security tools (41%) and time prioritization for the things that really matter (40%) stated as additional measures for relieving stress and burden.

As computing shifts from single-chip processors to multi-chip systems, traditional communication methods, such as Network-on-Chip (NoC) and Network-in-Package (NiP), are becoming less efficient. To address these limitations, scientists are exploring terahertz frequencies for high-speed data transfer, despite the challenge of noise interference, which complicates data decoding.

A research team from universities in Australia and the US has been studying wireless communication at the chip level and looking at ways to reduce noise. By applying Floquet engineering, a quantum technique that manipulates electron behavior, they found they were able to improve terahertz signal detection.

When implemented in a two-dimensional semiconductor quantum well (2DSQW), the approach successfully mitigated noise and boosted signal clarity. The team’s findings suggest that this method could pave the way for more effective and reliable wireless communication between chiplets, offering a potential solution for the efficiency challenges faced in multi-chip systems.

Wide-ranging applications

The team also developed a dual-signaling system that uses two receivers to monitor noise levels and adjust signals in real-time, further reducing error rates.

Writing forTech Xplore, researchers Kosala Herath and Malin Premaratne explained, “By overcoming the challenges of noise and signal degradation, our dual-signaling technique marks a key advancement in developing high-speed, noise-resistant wireless communication for chiplets. This innovation brings us closer to creating more efficient, scalable, and adaptable computing systems for the technologies of tomorrow.”

Their findings were published in the IEEE Journal on Selected Areas in Communications.

As we previously reported, universities are also looking at ways of boosting the potential of terahertz technology in order to unlock bandwidth for future telecommunications.

The University of Adelaide has developed a polarization multiplexer that doubles data transmission capacity at terahertz frequencies, while researchers at the University of Notre Dame showcased a silicon topological beamformer chip capable of splitting a single terahertz signal into 54 smaller beams.
