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.

Two more xAI co-founders are among those leaving after the SpaceX merger
Since the xAI-SpaceX merger announced last week, which combined the two companies (as well as social media platform X) for a reported $1.25 trillion valuation — the biggest merger of all time — a handful of xAI employees and two of its co-founders have abruptly exited the company, penning long departure announcements online. Some also announced that they were starting their own AI companies.
Co-founder Yuhai (Tony) Wu announced his departure on X, writing that it was “time for [his] next chapter.” Jimmy Ba, another co-founder, posted something similar later that day, saying it was “time to recalibrate [his] gradient on the big picture.” The departures mean that xAI is now left with only half of its original 12 co-founders on staff.
It all comes after changing plans for the future of the combined companies, which Elon Musk recently announced would involve “space-based AI” data centers and vertical integration involving “AI, rockets, space-based internet, direct-to-mobile device communications and the world’s foremost real-time information and free speech platform.” Musk reportedly also talked of plans to build an AI satellite factory and city on the moon in an internal xAI meeting.
Musk wrote on X Wednesday that “xAI was reorganized a few days ago to improve speed of execution” and claimed that the process “unfortunately required parting ways with some people,” then put out a call for more people to apply to the company. He also posted a recording of xAI’s 45-minute internal all-hands meeting that announced the changes.
“We’re organizing the company to be more effective at this scale,” Musk said during the meeting. He added that the company will now be organized in four main application areas: Grok Main and Voice, Coding, Imagine (image and video), and Macrohard (“which is intended to do full digital emulation of entire companies,” Musk said).

2026 Valentine’s romance scams and how to avoid them
NEWYou can now listen to Fox News articles!
Valentine’s Day should be about connection. However, every February also becomes the busiest season of the year for romance scammers. In 2026, that risk is higher than ever.
These scams are no longer simple “lonely hearts” schemes. Instead, modern romance fraud relies on artificial intelligence, data brokers and stolen personal profiles. Rather than sending random messages and hoping for a response, scammers carefully select victims using detailed personal data. From there, they use AI to impersonate real people, create convincing conversations and build trust at scale.
As a result, if you are divorced, widowed or returning to online dating after the holidays, this is often the exact moment scammers target you.

WHEN DATING APPS GET HACKED, YOUR PRIVATE LIFE GOES PUBLIC

The new face of romance scams in 2026
Romance scams are no longer slow, one-on-one cons. They’re now high-tech operations designed to target hundreds of people at once. Here’s what’s changed:
1) AI-generated personas that look and sound real
In the past, fake profiles used stolen photos and broken English. Today, scammers use AI-generated faces, voices and videos that don’t belong to any real person, making them almost impossible to reverse search.
You may be interacting with a profile that:
- Has years of realistic-looking social media posts
- Shares daily photos that match the story they tell
- Sends customized voice notes that sound natural
- Appears on “video calls” using AI face-mapping software.
Some scam networks even create entire fake families and friend groups online, so the person appears to have a real life, real friends and real history. To the victim, it feels like a genuine connection because the “person” behaves like one in every way.
2) Automated relationship scripts that adapt to you
Behind the scenes, many scammers now use software platforms that manage dozens of conversations at once. This is known as “scamware” and is incredibly hard to flag.
These systems:
- Track your replies
- Flag emotional triggers (grief, loneliness, fear, trust)
- Suggest responses based on your mood and history.
When you mention that you are widowed, the tone quickly becomes more comforting. Meanwhile, if you say you are financially stable, the story shifts toward so-called “business opportunities.” And if you hesitate, the system responds by introducing urgency or guilt. It feels personal, but in reality, you’re being guided through a pre-written emotional funnel designed to lead to one outcome: money.
3) Crypto and “investment romance” scams
One of the fastest-growing versions of romance fraud now blends love and money. A BBC World Service investigation recently revealed that many romance scams are now run by organized criminal networks across Southeast Asia, using what insiders call the “pig butchering” model, where victims are slowly “fattened up” with trust before being financially destroyed.
These operations use call center style setups, data broker profiles, scripted conversations and AI tools to target thousands of people at once. This is not accidental fraud. It’s an industry.
And the reason you were selected is simple. Your personal data made you easy to find, easy to profile and easy to target.
After weeks of trust-building, the scammer introduces:
- A “private” crypto platform
- A fake trading app
- A business or investment opportunity, “they use themselves.”
They may show fake dashboards, fake profits and even let you “withdraw” small amounts at first to build trust. But once larger sums are sent, the site disappears and so does the person. There is no investment. There is no account. And there is no way to recover the funds.

How scammers find you before you ever match
The biggest misconception is that romance scams begin on dating apps. They don’t. They begin long before that, inside massive databases run by data brokers. These companies collect and sell profiles that include:
- Your age and marital status
- Whether you’re widowed or divorced
- Your home address history
- Your phone number and email
- Your family members and relatives
- Your income range and retirement status.
Scammers buy this data to build shortlists of ideal victims.
The data brokers behind romance scams
They filter for:
- Age 55-plus
- Widowed or divorced
- Living alone
- Financially stable
- Not active on social media.
That’s how they know who to target before the first message is ever sent.
Why are widowed and retired adults targeted first?
Scammers aren’t cruel by accident. They target people who are statistically more likely to respond. If you’ve lost a spouse, moved recently or reentered the dating world, your personal data often shows that. That makes you a priority target. And once your name lands on a scammer’s list, it can be sold again and again. That’s why many victims say, “I blocked them, but new ones keep showing up.” It’s not a coincidence. It’s data recycling.
How the scam usually unfolds
Most romance scams follow the same pattern:
- Friendly introduction: A warm message. No pressure. Often references something personal about you.
- Fast emotional bonding: They mirror your values, your experiences, even your grief.
- Distance and excuses: They can’t meet. There’s always a reason: military deployment, overseas job, business travel.
- A sudden “crisis”: Medical bills, business losses, frozen accounts, investment opportunities.
- Money requests: Wire transfers, gift cards, crypto or “temporary help.”
By the time money is involved, the emotional connection is already strong. Many victims send thousands before realizing it’s a scam.
The Valentine’s Day cleanup that stops scams at the source
If you want fewer scam messages this year, you need to remove your personal information from the places scammers buy it. That’s where a data removal service comes in. While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy.
These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.
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.

- Never send money to someone you haven’t met in person

- Verify profiles with reverse image searches
- Don’t share personal details early

Kurt’s key takeaways
Romance scams are no longer random. They are targeted, data-driven and emotionally engineered. This Valentine’s Day, the best gift you can give yourself is privacy. By removing your personal data from broker databases, you make it harder for scammers to find you, profile you and exploit your trust. And that’s how you protect not just your heart, but your identity, your savings and your peace of mind.

Uber Eats adds AI assistant to help with grocery shopping
Uber announced a new AI feature called “Cart Assistant” for grocery shopping in its Uber Eats app.
The new feature works a couple different ways. You can use text prompts, as you would with any other AI chatbot, to ask it to build a grocery list for you. Or you can upload a picture of your shopping list and ask it to populate your cart with all your favorite items, based on your order history. You can be as generic as you — “milk, eggs, cereal” — and the bot will make a list with all your preferred brands.
And that’s just to start out. Uber says in the coming months, Cart Assistant will add more features, including “full recipe inspiration, meal plans, and the ability to ask follow up questions, and expand to retail partners.”
But like all chatbots, Uber acknowledges that Cart Assistant may make mistakes, and urges users to double-check and confirm the results before placing any orders.
It will also only work at certain grocery stores, with Uber announcing interoperability at launch with Albertsons, Aldi, CVS, Kroger, Safeway, Sprouts, Safeway, Walgreen, and Wegmans. More stores will be added in the future, the company says.
Uber has a partnership with OpenAI to integrate Uber Eats into its own suite of apps. But Uber spokesperson Richard Foord declined to say whether the AI company’s technology was powering the new chatbot in Uber Eats. “Cart Assistant draws on publicly available LLM models as well as Uber’s own AI stack,” Foord said in an email.
Uber has been racing to add more AI-driven features to its apps, including robotaxis with Waymo and sidewalk delivery robots in several cities. The company also recently revived its AI Labs to collaborate with its partners on building better products using delivery and customer data.
