Breakthrough device promises to detect glucose without needles
NEWYou can now listen to Fox News articles!
The idea of tracking blood sugar without needles has challenged health tech for years. For people with diabetes, constant monitoring is critical, yet the tools remain uncomfortable and invasive. Finger pricks hurt. Traditional continuous glucose monitors still sit under the skin. That daily burden adds up fast.
Recently, one small device has been drawing significant attention for tackling that problem in a very different way.

WEIGHT LOSS EXPERTS PREDICT 5 MAJOR TREATMENT CHANGES LIKELY TO EMERGE IN 2026

Why noninvasive glucose tracking matters
Blood sugar levels can rise or fall quickly. When changes go unnoticed, the risks increase, from long-term organ damage to sudden hypoglycemia. Monitoring can be especially difficult for:
- Small children
- Older adults
- Anyone who struggles with needles
At the same time, glucose tracking has surged among people without diabetes. As GLP-1 medications gain popularity, many people now track their blood sugar to understand how food affects their bodies. The need for simpler tools keeps growing.
Even Apple has spent years trying to bring no-prick glucose tracking to wearables. Despite heavy investment, the feature has yet to arrive.
NEEDLE-FREE GLUCOSE CHECKS MOVE CLOSER TO REALITY

How the PreEvnt isaac monitors glucose using breath
One of the most talked-about health devices at CES 2026 came from PreEvnt. Its product, called isaac, takes a nontraditional approach to glucose awareness. Instead of piercing skin or using optical sensors, isaac analyzes your breath.
The device measures volatile organic compounds, especially acetone, which has long been associated with rising blood glucose. That sweet fruity breath is a known marker of diabetes. By detecting changes in those compounds, isaac can alert users to potential glucose events. The device is small, about the size of a quarter, with a loop so it can be worn on a lanyard or clipped to clothing or a bag.
The breath-based design is intended to reduce how often users need finger-prick blood tests, while providing early alerts for glucose-related changes.
The device is named after the inventor’s grandson, Isaac, who was diagnosed with Type 1 diabetes at just 2 years old. The inventor, Bud Wilcox, wanted to reduce the number of painful finger pricks his grandson faced each day. That personal motivation led to years of collaboration with scientists, designers and engineers. Research and development included work with Indiana University under the direction of Dr. M. Agarwal. The goal was simple but ambitious: Alert families to blood sugar events earlier while reducing the physical and emotional toll of constant testing.
How the isaac device fits into daily life
Isaac is designed to fit into everyday routines. Users breathe into the device, which processes the reading and sends the data to a companion smartphone app. The app, still in its final stages of development, focuses on awareness and safety. Current features include:
- A timeline for logging meals
- A history of breath readings
- Alerts that can notify emergency contacts
This matters because people with diabetes can become disoriented or incapacitated during hypoglycemic events. Early alerts give caregivers or family members a chance to step in. A single charge lasts all day and supports multiple breath tests. The device comes with a USB-C charging cradle and cable.
Who isaac is designed for
According to PreEvnt, isaac is being developed for:
- Type 1 diabetics
- Type 2 diabetics
- Prediabetics
It may also appeal to people focused on metabolic health. As mentioned, the device is still undergoing development and FDA review and is not yet for sale in the U.S. The companion app will launch on iOS and Android closer to availability.
TYPE 1 DIABETES REVERSED IN LANDMARK STUDY, PAVING THE WAY FOR HUMAN STUDIES

Clinical trials and FDA review for the isaac device
PreEvnt first introduced isaac publicly at CES 2025. Later that year, the device entered active human clinical trials. Those studies compare isaac’s breath-based alerts with traditional blood glucose monitoring methods.
Trials began with adolescents who have Type 1 diabetes and later expanded to adults with Type 2 diabetes. The company is now working toward regulatory review with the U.S. Food and Drug Administration. Because this technology is new, PreEvnt is pursuing a de novo pathway, which allows devices to be evaluated while standards are still being defined. According to the company, regulators have shown strong interest as the data continues to come in.
Isaac does not claim to replace medical-grade glucose meters. The device is being developed to supplement existing monitoring methods by offering breath-based alerts tied to glucose-related changes.

Kurt’s key takeaways
Noninvasive glucose monitoring has long felt like a future promise that never quite arrives. The attention around isaac at CES 2026 suggests that promise may finally be getting closer. If clinical trials continue to deliver strong results and regulators give approval, breathing into a small device could one day replace at least some finger pricks. For families living with diabetes, that shift could make daily life easier and safer.

Splatoon Raiders preorders for the Switch 2 are nearly 20 percent off
Nintendo recently announced a new pricing policy, which knocks $10 off the cost of digital versions of future first-party titles exclusive to the Nintendo Switch 2. Splatoon Raiders, for instance, is available for preorder ahead of its July 23rd release for $49.99 digitally or $59.99 for the physical edition. However, Amazon and Walmart are the exception in how they’re pricing preorders for the cartridge version. Right now, you can reserve the upcoming title at both retailers for $49.94, which is a few cents cheaper than the digital version. Raiders isn’t a sequel to Splatoon 3, but rather a spinoff that has similar third-person, paint-splatting gameplay set in new locales.
The same $10 discount is in effect for Yoshi and the Mysterious Book, a side-scrolling adventure with a gorgeous storybook art style that comes out on May 21st. The price of the physical version is $69.99, but Amazon and Walmart are currently offering it for $59.88, which is similar to the digital edition’s price. Given that prices on many tech and gaming-related products are increasing, it’s nice to see notable discounts on physical Switch 2 games. If you’re looking for other gaming deals, we’ve pulled together the best discounts from Amazon’s weeklong Gaming Week sale.
Update, May 1st: Updated price and availability to reflect the fact that Amazon is now matching Walmart’s preorder promotion on both Switch 2 titles.

ADT data breach exposes customer information
NEWYou can now listen to Fox News articles!
ADT has confirmed a new data breach, and it comes with a familiar twist. A well-known cybercrime group is reportedly demanding money and threatening to leak data if it does not get paid.
The group behind it, ShinyHunters, says it stole more than 10 million records. ADT has not confirmed that number, but it says attackers accessed customer data.
According to the company, “ADT’s cybersecurity systems detected unauthorized access to a limited set of customer and prospective customer data on April 20, and the company’s response protocols activated immediately, terminating the intrusion, launching a forensic investigation with leading third-party cybersecurity experts, and notifying law enforcement.”

GOOGLE CONFIRMS DATA STOLEN IN BREACH BY KNOWN HACKER GROUP
ADT confirmed a new data breach after hackers claimed they stole millions of records and threatened to leak the data. The company said customer payment information and security systems were not affected. (Kurt “CyberGuy” Knutsson)
What data was exposed in the ADT breach
ADT says, “The investigation confirmed that the information involved was limited to names, phone numbers, and addresses. In a small percentage of cases, dates of birth and the last four digits of Social Security numbers or Tax IDs were included.
Here is the part that may bring some relief. ADT tells CyberGuy, “Critically, no payment information, including bank accounts or credit cards, was accessed, and customer security systems were not affected or compromised in any way.”
Still, this kind of personal data carries real value. Even without full Social Security numbers, attackers can use it to build convincing scams that feel personal.
How hackers may have accessed ADT systems
This breach may have started with a phone call. ShinyHunters told BleepingComputer it used a voice phishing attack, often called vishing, to compromise an employee’s Okta single sign-on account. The group claims that access allowed it to steal data from ADT’s Salesforce system. ADT has confirmed unauthorized access to customer and prospective customer data, but it has not publicly confirmed that specific attack method. This approach has become more common. Instead of hacking systems directly, attackers target people. One successful interaction can unlock multiple systems at once.
In a statement to CyberGuy, ADT said its response worked as intended.
“ADT’s protocols performed as designed: the breach was identified quickly, the threat was contained, and the scope was limited,” the company said. “ADT has directly notified all impacted individuals and will offer complimentary identity protection services as appropriate. Protecting customers is not just a priority; it is the foundation of what ADT does. The company remains committed to investing in and strengthening the cybersecurity infrastructure that its customers and their families depend on.”
RANSOMWARE ATTACK EXPOSES SOCIAL SECURITY NUMBERS AT MAJOR GAS STATION CHAIN
A sign in front of a suburban home in San Ramon, Calif., indicates the house is secured by an ADT alarm system to prevent burglaries and break-ins.
Why the ADT data breach matters for you
On the surface, this breach may seem limited. No financial data. No system control. That sounds contained. The reality is more complicated.
Names, phone numbers and addresses create a powerful starting point for scams. Add even partial Social Security data, and the risk increases. Criminals can use that information to impersonate companies, reset accounts or trick victims into handing over more sensitive details.
This also raises a bigger issue. Even companies focused on security can become targets. That should change how you think about your own exposure.
ADT’s history of data breaches
This isn’t the first time ADT has dealt with a data breach. The company disclosed incidents in August and October of 2024 that exposed customer and employee information.
When breaches happen more than once, it raises questions about internal security practices and how attackers keep finding a way in.
At the same time, it highlights a broader trend. Cybercriminal groups like ShinyHunters are focusing on identity systems and employee access instead of traditional hacking methods.
Ways to stay safe after a data breach
After a breach like this, the goal is to reduce how much attackers can do with your information and make yourself a harder target going forward.
1) Watch for targeted scams
If someone claims to be from a company like ADT, pause before responding. Scammers often use real details to sound convincing. Hang up and contact the company directly using a verified number.
2) Limit your exposed personal data
Consider using a personal data removal service. These tools help remove your information from data broker sites, which reduces what scammers can find about you online. 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.
3) Add identity theft monitoring
Identity theft monitoring can alert you to suspicious activity tied to your name or Social Security number early, which gives you a chance to act before damage spreads. See my tips and best picks on Best Identity Theft Protection at CyberGuy.com.
4) Strengthen your passwords and account security
Use a password manager to create and store strong, unique passwords. If you reused passwords anywhere, especially on email or banking accounts, update them right away to prevent account takeovers. Check out the best expert-reviewed password managers of 2026 at CyberGuy.com.

5) Turn on two-factor authentication
Adding an extra login step, such as two-factor authentication (2FA), makes it much harder for attackers to break into your accounts, even if they have your credentials.
6) Keep your devices protected
Make sure your devices run updated security software. Many modern tools can detect suspicious activity before it turns into a bigger problem.
7) Freeze your credit if sensitive data was exposed
If your Social Security number or even part of it may be involved, consider placing a credit freeze with the major bureaus. This prevents new accounts from being opened in your name without your approval.
8) Review your financial and account activity
Keep an eye on bank accounts, credit cards and important logins for unusual activity. Even small, unfamiliar charges or login alerts can be an early warning sign.
9) Use strong antivirus protection
Install and maintain strong antivirus software on your devices. It can detect suspicious activity, block malware and help stop threats before they gain access to your data. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android and iOS devices at CyberGuy.com.
10) Be cautious with account recovery attempts
Attackers often try to reset your passwords using information they already have. If you get unexpected password reset emails or codes, treat them as a warning sign, not a routine message.
11) Opt for a reliable home security system
While ADT is one of the largest home security companies in the United States, the recent breach of customer information highlights potential vulnerabilities despite the company’s assurance that home security systems were not compromised. There are many other options in the market, whether you prefer a professionally installed system or a do-it-yourself one.
For reference, you can check out my guide on the best home security systems at CyberGuy.com, where I’ve listed four of my favorite options. You might also want to find out if your home insurance offers a discount for installing robust security protection.
Kurt’s key takeaways
If your data was part of this breach, the risk does not end with the initial incident. In many cases, it is just getting started. You may begin to see more targeted scam calls or emails. Messages might include your name or reference your address to appear legitimate. That level of detail can make even cautious people hesitate. Even if you have never used ADT, this is a reminder of how often personal data circulates behind the scenes. Once it is out there, it can be reused in ways you never expected. The bigger takeaway is simple. Breaches like this are less about a single company and more about how exposed personal data has become across the board.

Aurzen’s tiny trifold projector is almost 40 percent off right now
Not all trifolds are created equal — just ask our own Allison Johnson, who recently spent time with Samsung’s ill-fated Galaxy phone. Aurzen’s Zip projector is the kind of trifold gadget we can fully get behind, though, and it’s currently on sale at Amazon for $259.99 ($140 off). You can also pick it up in several colors directly from Aurzen for the same price, or in the gold shade for a new low of $249.99.
While not nearly as powerful as Anker’s Nebula P1 and other portable projectors we’ve recently tested, the Zip is surprisingly capable despite its small stature and battery-powered operation. The snake-like 720p projector offers up to 100 lumens of brightness — meaning it will work best in dark environments, or in brighter rooms when viewing a smaller image — while its built-in battery should last about 80 minutes based on our real-world testing. That’s not exactly marathon battery life, but it’s easy enough to top off the Zip using a power bank or wall adapter.
In terms of support, the Zip can quickly connect to iPhones via AirPlay and to Android devices over Miracast, Smart View, and similar standards, allowing you to wirelessly mirror everything you can see on your phone. You can use it to watch any movies you’ve downloaded on your device, peruse your social feeds, or get in a quick session with your favorite game. It works in both landscape and portrait orientations, too, and supports Bluetooth, letting you listen privately with headphones or pair it to your favorite speaker.
The biggest downside to the Zip, at least for some folks, is that you won’t be able to use it to watch content from services like Netflix, Hulu, and HBO Max due to copyright restrictions. Aurzen does make a USB-C dongle that allows you to stream DRM-protected content, if you truly can’t get by without watching the latest episode of Euphoria. You’ll have to pay a whopping $109 for the privilege, or find another way.
