1. Location tracking
Your phone’s GPS isn’t just for directions
Every time you check the weather, tag your location on Instagram or ask Google Maps for the quickest route, you’re sharing your whereabouts. That’s thanks to Location Tracking, a feature built into most apps and devices that uses GPS, Wi-Fi, Bluetooth or cell towers to pinpoint your location.
Here’s the catch: Many apps track you even when you’re not using them. Some use this data to serve local content or ads, while others collect and sell it to third parties.
How to protect yourself:
- Check which apps have location access in your settings
- Switch from “Always” to “While Using the App”
- Consider turning off location services entirely when you don’t need them
Knowing when and how you’re being tracked is the first step to stopping it.

2. App permissions
What your apps know about you (and maybe shouldn’t)
Before you can use that new photo editor or budgeting tool, it probably asked for a few things — access to your camera, contacts, microphone, maybe even your calendar. These are called App Permissions, and they determine what parts of your phone an app can interact with.
WHAT IS ARTIFICIAL INTELLIGENCE (AI)?
While some requests are necessary (e.g., a video app needs camera access), others can be excessive or even suspicious. For example, why does a flashlight app need your location or call logs?
Tips for staying in control:
- Review permissions when installing apps
- Regularly audit your app settings
- Delete apps you no longer use
Your data shouldn’t be the price of convenience. Set boundaries.

3. Two-factor authentication (2FA)
A second lock on your digital front door
Passwords aren’t perfect. That’s where two-factor authentication (2FA) comes in. It adds an extra layer of protection by requiring two forms of identification before granting access to your account, typically something you know (a password) and something you have (a text code or authentication app).
Many major apps and platforms now support 2FA, and enabling it can help block hackers, even if they steal your password.
Most common types of 2FA:
- Text or email codes
- Authenticator apps like Google Authenticator or Authy
- Biometric verification (fingerprint or face ID)
Activate 2FA where you can. It’s one of the simplest ways to level up your mobile security.
4. Mobile ad ID
The invisible label that tracks your habits
Behind the scenes, your phone is assigned a unique string of numbers and letters called a mobile advertising identifier (Mobile Ad ID). It helps advertisers track your behavior across apps and websites to build a profile of your interests.
While it doesn’t include your name, it can be linked to your device and used to serve targeted ads. Think of it as a digital name tag for marketing purposes.
Want to opt out? You can:
- iPhone: Go to Settings > Privacy & Security > Tracking
- Android: Settings > Privacy > Ads, and reset or delete your Ad ID
You’re not obligated to let your phone advertise you.

5. VPN (virtual private network)
Your personal privacy tunnel
A VPN is like a secret tunnel for your internet connection. It hides your online activities and helps keep your personal information safe when you’re using the internet, especially on public Wi-Fi.
In addition to protecting your information from prying eyes, a VPN also hides your real location. It allows you to connect to the internet through a server in another part of the world, which makes it appear as though you’re browsing from a different location. This is useful for security (protecting your privacy) and for accessing content that might be restricted in certain areas.
When you connect to public Wi-Fi at a coffee shop or airport, your data can be exposed to hackers and snoops. That’s where a VPN (virtual private network) comes in. It encrypts your internet traffic and routes it through a secure server, hiding your IP address and protecting your activity.
Think of it as a private tunnel for your internet usage, shielding your data from prying eyes.
What VPNs are great for:
- Protecting your connection on public Wi-Fi
- Accessing region-locked content
- Hiding your online activity from advertisers or your internet provider
Just make sure to choose a trustworthy VPN. Some free VPNs may log your data or slow your phone down. A reliable VPN is essential for protecting your online privacy and ensuring a secure, high-speed connection.

It’s amazing how good Alienware’s $350 OLED monitor is
I’ve recommended several OLED gaming monitors to readers over the years, and I’ve finally taken my own advice to buy one. Alienware’s new 27-inch 1440p QD-OLED has all the features that I want and a low $350 price that was too tempting to ignore.
The AW2726DM model has five things that make it stand out for the price: a 1440p QD-OLED screen with lush contrast, a fast 240Hz refresh rate, a semi-glossy screen coating to enhance details, a low-profile design without flashy RGB LEDs, and a great warranty (three years with coverage for burn-in).
I’ve been using Alienware’s new monitor for a couple days, and I’ve already spent hours with it playing Marathon. It was my first opportunity to see Bungie’s new first-person extraction shooter in its full HDR glory, and I can never go back. Switching on HDR wasn’t automatic, though it already looked so much better than my IPS panel without being activated.
Enabling it transformed how Marathon looked for the better, but made everything else about the OS look pretty washed-out. It’s a Windows issue, not an Alienware issue. It’s easy to enable HDR every time I launch a game and disable it afterward with the Windows + Alt + B keyboard shortcut, but unfortunately triggers HDR for all connected displays. This includes my IPS monitor that imbues everything with a terrible gray hue when HDR is on. So, using the system settings is the best way to adjust HDR for just the QD-OLED.
I landed on this QD-OLED after having spent a ton of time researching pricier models. The unanimous takeaway from reviewers was that LG’s Tandem RGB WOLED panels are some of the brightest out there, but also tend to exhibit lousy gray uniformity in dark scenes. QD-OLED monitors, on the other hand, offer slightly better contrast than WOLED and don’t suffer from those same uniformity issues. However, blacks sometimes appear as dark purple in bright rooms on QD-OLED panels, meaning they’re ideal for rooms that don’t have a bunch of light bouncing around.
There’s no perfect choice, and honestly I got tired of doing research, so I jumped in with the cheapest OLED. I’m glad that I did. Shopping for an OLED gaming monitor can be hard, but it can also be this easy. AOC makes a model that’s discounted to $339.99 at the time of publishing, and its specs are comparable.
As expected, the AW2726DM isn’t a cutting-edge monitor. Its QD-OLED panel isn’t as fast or as bright as some other pricier options, and it doesn’t have USB ports for connecting accessories. Considering its low price, it’s easy for me to overlook those omissions. I’d have a much harder time accepting them in a pricier display.
The fact that I mostly use my computer for text-based work at The Verge is what prevented me from upgrading to an OLED monitor. My 1440p IPS monitor is bright, it’s good at showing text clearly, and it has a fast refresh rate for gaming. Alienware’s QD-OLED is less bright, and some might be bothered by how text looks (I have to really squint to see the slight fringing from this QD-OLED’s subpixel layout). But I have a life outside of work, which includes playing a lot of PC games. That’s the slice of myself I bought this monitor for, and I’m so happy I did.

Michael and Susan Dell surpass $1 billion in donations backing AI-driven hospital project
NEWYou can now listen to Fox News articles!
Billionaire Michael Dell and his wife, Susan Dell, have become the first donors to give more than $1 billion to the University of Texas at Austin, funding a massive new medical research campus and hospital system powered by artificial intelligence.
The couple’s latest investment includes a $750 million gift to help build the UT Dell Medical Center, a planned “AI-native” hospital expected to open in 2030 as part of a more than 300-acre advanced research campus.
University officials said the project will integrate research, clinical care and advanced computing to improve early disease detection, personalize treatment and expand access to care in the rapidly growing Austin region.
The Dells’ support builds on decades of contributions to UT, including funding for its medical school, scholarships and research programs.

“By bringing together medicine, science and computing in one campus designed for the AI era, UT can create more opportunity, deliver better outcomes, and build a stronger future for communities across Texas and beyond,” Michael Dell and Susan Dell said.
The gift ranks among the largest in the history of higher education, alongside major contributions like Phil Knight’s $2 billion pledge to Oregon Health & Science University and Michael Bloomberg’s $1.8 billion donation to Johns Hopkins University.
The new UT Dell Medical Center will be developed in collaboration with MD Anderson Cancer Center, integrating cancer care into a system designed to connect prevention, diagnosis and treatment.

“We will deliver better outcomes for patients by providing research-driven cancer care that is precise, compassionate and hope-filled,” Peter WT Pisters, president of UT MD Anderson, said.
Officials said the facility will be built from the ground up to incorporate AI, rather than retrofitting older infrastructure — an approach they say could transform how hospitals operate.
Independent experts have cautioned that AI in health care can introduce risks if not carefully validated. A widely cited study published in the journal Science by researchers at the University of California, Berkeley and the University of Chicago found that a commonly used healthcare algorithm underestimated the needs of Black patients due to biased training data, highlighting broader concerns about equity in AI-driven systems.
The project also includes funding for undergraduate scholarships, student housing and the Texas Advanced Computing Center, where officials are developing one of the nation’s most powerful academic supercomputers.

Texas Gov. Greg Abbott said the investment will help position the state as a national leader in healthcare innovation.
“Texas already dominates in technology, energy and business, and now we will further cement our leadership in health care innovation as well,” Abbott said.

The university said it plans to break ground on the medical center later this year and has launched a broader campaign to raise $10 billion over the next decade.
