Australia debuts first multi-story 3D printed home – built in just 5 months

NEWYou can now listen to Fox News articles!

A major milestone in construction has arrived. This time from Western Australia. Contec Australia has completed the nation’s first multi-story 3D concrete printed home. Located in Tapping near Perth, the two-story residence was finished in just five months. Most impressive? The structural walls were 3D printed in only 18 hours of active printing time.

This matters because it points to where housing might be heading here, too. With rising costs, labor shortages and a push for more sustainable building methods, this kind of breakthrough could shape the future of American neighborhoods.

Why this build is a game-changer

Contec’s project isn’t just a prototype. It demonstrates how 3D concrete printing can bring major benefits to everyday housing. Compared to traditional masonry construction, the Tapping home achieved:

  • 22% cost savings on structural walls
  • 3x the strength of brick (50MPa vs 15MPa)
  • Faster delivery, with the entire project completed in just five months

How 3D concrete printing works

Instead of stacking bricks, Contec’s robotic printer extrudes a specialized concrete mix based on a digital 3D model. The mix sets in under three minutes, allowing new layers to be stacked without scaffolding or formwork.

Benefits that could apply in the U.S.

Speed: Structural walls finished in 18 hours; full build completed in five months.
Cost efficiency: 22% cheaper than comparable masonry builds in WA.
Design freedom: Complex shapes, curves and openings without added expense.
Sustainability: 30% lower CO₂ emissions than conventional concrete and minimal waste.
Durability: More than three times stronger than brick, fire- and water-resistant and able to withstand harsh weather.

How this compares to 3D printed homes in the U.S.

You may have already heard of Icon, the Texas-based startup that has been pioneering 3D printed homes. Icon’s builds include entire neighborhoods of single-story houses in Austin, as well as experimental multi-level projects. However, most of Icon’s multi-story designs rely on a hybrid approach, with 3D printing for the ground floor and timber or steel frames for the upper levels.

That’s what makes the Tapping project stand out. Contec printed the structural walls for both stories in just 18 hours of active printing time, something not yet widely seen in the U.S. This could signal the next step for American 3D printing: scaling beyond single-story housing into more complex multi-story designs.

How much does a 3D printed home cost?

One of the biggest questions people have is price. Contec hasn’t shared the exact cost of the Tapping home, but the company says it delivered the structural walls 22% cheaper than a standard masonry build. That saving adds up when you consider how much of a home’s budget goes toward labor and materials.

In the U.S., companies like Icon have priced 3D printed homes starting around $100,000 to $150,000, depending on size and finishes. While final costs vary by region, land and design, the potential savings from reduced labor and faster timelines make 3D printing an attractive option as housing costs continue to rise.

Meta is reportedly working on smart glasses that would be recording all the time

Meta is reportedly working on smart glasses that would be recording all the time

Meta might be the next company to make an always-on AI wearable. The company is working on prototype “super sensing” always-aware smart glasses that could continuously record audio and snap photos “every few seconds,” according to the Financial Times. The wearer could then ask Meta AI about the captured audio and images.

However, the images and audio might not be directly available to the user. Here’s how the FT describes one way the glasses could use the data:

In one proposed system, raw footage and audio would not be stored by Meta or made available to the user, several people said. Instead, the metadata from that audio and images would be extracted and uploaded to the server for Meta’s AI to query, which proponents argue would have fewer privacy implications.

But currently, Meta is planning for the LED recording indicator to remain off in “super sensing” mode, the FT reports. In a July 2025 whitepaper, the company said that it would reserve the LED indicator for “active capture” scenarios where the user is saving photos or videos, and leave it off during “AI Feature” use — such as scanning a menu — to avoid users becoming too used to the indicator. (If the indicator was on during the “super sensing” mode, it might also be harder to know when the glasses are actually recording video.)

Meta is also discussing if it would use the captured data for training its AI models. It may also bring the “super sensing” features to glasses it has already released, the FT says.

“While we don’t comment on internal prototypes, we’re committed to getting our glasses right because they need to be loved by both people wearing them and those around them,” Meta spokesperson Dave Arnold says in a statement to The Verge. Arnold also notes that “Our approach has been to develop new technologies that will help people throughout their day, with privacy built in from the ground up.”

Meta hasn’t been shy about some type of always-aware glasses being a possibility. CEO Mark Zuckerberg, in the company’s Q1 2026 earnings call, said that he was “really excited to see the glasses evolve from being able to answer questions to being able to be a personal agent that’s with you all day long, helping you remember things and achieve your goals.” In a March blog post about new Ray-Ban Meta glasses, the company wrote that “with ongoing software updates, Meta AI on glasses will transition from something you have to prompt with a question each time, to a more continuous, in-the-moment assistant that can help throughout the day.”

Get a  credit when you reserve Samsung’s upcoming Galaxy phones

Even though they haven’t been officially announced yet, Samsung is giving you a chance to save some cash when you preorder what we’re expecting to be the brand’s updated Galaxy Z Fold phones. The next Galaxy Unpacked event will take place on July 22nd, 2026, and features the tagline “A new shape unfolds.” In addition to seeing updated versions of the existing Flip and Fold form factors, we anticipate the debut of a new, wider foldable phone. If you register your interest ahead of time and end up preordering one of the new phones shortly after they’re announced, Samsung will give you a $30 store credit at checkout.

There are some caveats to this offer. You have to use the credit when you preorder the phone. No saving it for later. Also, the credit can’t be applied to the cost of the phone either, so you’ll have to put it towards the cost of accessories or extra services. Samsung specifically calls out that select Galaxy rings, earbuds, watches, and tablets are eligible, or you can use it to help pay for Samsung Care Plus.

There are no downsides to registering your interest, so if you think you might be interested in buying one of the upcoming phones, it’s worth filling out the form. As long as you use the same email during checkout, the credit will be automatically applied.

Apple AI security update proves hackers move fast

Apple AI security update proves hackers move fast

NEWYou can now listen to Fox News articles!

A security update rarely feels dramatic. You see the alert, promise yourself you will install it later and then go right back to whatever you were doing. This time, Apple is giving you a stronger reason to pay attention.

Apple released iOS 26.5.2, iPadOS 26.5.2 and macOS Tahoe 26.5.2 on June 29, 2026. The updates include security fixes for vulnerabilities tied to the kernel, WebKit and WebRTC. Apple says these fixes were first made available through the iOS 26.6, iPadOS 26.6 and macOS Tahoe 26.6 betas before being pushed out early to everyone.

That is the part that should make you pause. Apple usually rolls many security fixes into larger software updates. This time, the company moved faster.

Why Apple released this AI security update early

Apple reportedly accelerated the updates because artificial intelligence can help speed the creation of malicious hacking tools. Once a fix appears in a beta, attackers may be able to study it, reverse-engineer the weakness and move faster than before.

Apple said there was no evidence that the newly patched vulnerabilities had been exploited. Still, the company wanted to shrink the time between when fixes were first visible and when they reached your devices.

That is a major shift. It suggests Apple sees AI as a force that changes the timing of security. A flaw that once gave defenders more breathing room may now become a race.

What Apple fixed in iOS 26.5.2

Apple’s iOS 26.5.2 and iPadOS 26.5.2 notes list fixes for iPhone 11 and later, along with several supported iPad models. The security content includes kernel vulnerabilities that could let an app crash the system, corrupt kernel memory or leak sensitive kernel state.

The update also fixes multiple WebKit issues. WebKit powers Safari and web content inside many apps. Some of these flaws involved malicious web content that could lead to crashes, memory corruption, data leaks or sandbox escapes.

Apple also fixed WebRTC issues that could be triggered by malicious web content and lead to Safari or process crashes.

Why AI hacking tools change the security race

AI can help legitimate researchers find bugs faster. That is good when the work leads to stronger software and responsible disclosure. However, the same general capability can also help bad actors move faster. A criminal does not need to understand every line of code if an AI tool can help summarize a patch, compare software changes or suggest where a weakness may be hiding.

That is why Apple’s move is important. It shows that big tech companies may need to release security fixes sooner and more often, even when those updates do not include flashy new features. The wider AI world adds pressure here. Frontier AI companies have released or tested systems with stronger coding and cybersecurity capabilities. Some models are available only through limited previews, approved access or extra safeguards because of their potential cyber use.

Similar efforts are also emerging outside the United States. Several international AI labs and security companies now promote models designed to find vulnerabilities, analyze code and assist cyber defense. The takeaway for you isn’t that AI is automatically bad. The real point is speed. Security teams, attackers and AI tools are now moving on a shorter clock.

How to update your iPhone or iPad

Before you update, plug in your device and connect to Wi-Fi. You may also want to back up your iPhone or iPad first.

Then do this: Open Settings > General > Software Update > Download and Install.

After the update finishes, go back to Settings > General > Software Update > Automatic Updates. Make sure automatic updates are turned on. Apple also lets your device automatically install system file updates that improve security without changing the full software version. If you do not see the update right away, check again later. Apple releases updates in stages, and your device also needs enough battery and storage.

How to update your Mac

On a Mac, start with a backup. Then click the Apple menu > System Settings > General > Software Update . Choose Update Now if macOS Tahoe 26.5.2 appears.

Next, check your background update settings. On macOS Tahoe 26 or later, go to Apple menu > System Settings > General > Software Update . Click the More Info button next to Automatic Updates and make sure Install system data files and security updates is turned on.

If your Mac runs Sonoma or Sequoia, look for Safari 26.5.2 in Software Update as well. That Safari update may be the protection your Mac needs if you are not on Tahoe.

BEWARE OF HACKERS SHOWING UP PRETENDING TO BE IT

What this Apple security update means to you

You may see more security updates that feel sudden or small. That can be annoying, especially when you are busy or your device needs to restart.

Still, these updates are becoming more important. Apple is reacting to a world where AI can help shorten the time between a public fix and a possible attack.

So, when your iPhone, iPad or Mac asks you to update, do not treat it like background noise. The update may be closing a door someone else is already trying to find.

How to stay safe after the Apple security update

Installing the Apple AI security update is the best first move. After that, tighten a few habits that make attacks harder.

1) Keep your apps updated

Your operating system is only part of the security picture. Outdated apps can still create risk, especially if they handle messages, web links, photos, files or account logins. Open the App Store and install available updates regularly.

2) Watch out for suspicious links

Be careful with links in texts, emails and social media messages. WebKit and browser flaws are a reminder that malicious web content can be part of an attack. When in doubt, open the official app or website yourself instead of tapping a link.

3) Use strong passwords and two-factor authentication

Use strong, unique passwords for every account and store them in a password manager. Then turn on two-factor authentication (2FA) wherever possible. If one password gets exposed, you do not want it opening the door to your email, bank or Apple account.

4) Use strong antivirus protection

Use strong antivirus protection on your Mac and other connected devices. It can help catch malicious files, phishing attempts and suspicious activity before they do damage. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android and iOS devices at CyberGuy.com.

5) Back up your data regularly

Back up your iPhone, iPad and Mac before problems hit. A recent backup can help you recover faster if an update fails, your device gets stolen or malware locks you out of important files. CyberGuy’s guide to backing up your devices walks you through ways to protect your files using cloud storage, an external drive or both.

6) Use a personal data removal service

Use a personal data removal service to reduce how much of your personal information is floating around online. Data brokers and people-search sites can expose your name, address, phone number and relatives. Scammers can use those details to make phishing messages feel more believable. Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting CyberGuy.com.

Kurt’s key takeaways

Apple’s early security release shows how fast the cyber threat landscape is changing. The company says there is no evidence these newly patched flaws were exploited, but it still moved the fixes out before the wider 26.6 release. That tells me the old habit of waiting weeks to update is getting riskier. AI can help defenders, but it can also help criminals study weaknesses faster. My advice is direct: update your Apple devices now, turn on automatic security updates and stop putting off patches that protect the phone and computer you use every day.

Do you think AI will make your devices safer because companies can find flaws faster, or more vulnerable because hackers can move faster too? Let us know by writing to us at CyberGuy.com.
