How to trace and block anonymous calls
Spam calls are on the rise, and the scammers behind those calls are getting more and more sophisticated. Because of this, it can be harder to determine whether or not a call is actually a scam, especially if the scammer has phone spoofed a legitimate number that you may recognize.
Often, people can quickly identify a scam call, especially when their caller ID shows “Unknown Caller.” But what happens when this anonymous caller persistently calls again and again? This can become irritating very quickly. The usual solution is to block the number, but this is easier said than done when the actual phone number is hidden on the Caller ID.
Fortunately, there are several effective methods and tools available to help block and even trace anonymous calls, ensuring these nuisance calls stop for good.

3 ways to block anonymous calls
Spam callers can find all sorts of ways to trick you into answering the phone and giving up your sensitive data. When you don’t answer or don’t give them what they want, they may keep calling and calling.
Some scammers even rely on robots to initiate what’s known as robocalls to make it easier to call their victims over and over again at a faster rate without requiring a human to do it. Whatever the case may be, here are ways you can get ahead of them and stop them from bothering you:
1) Use your phone’s built-in features
To start, your phone already has built-in features that can help you block anonymous calls or at least prevent them from trying to call you in the first place:
On iPhone:
On iPhone, the best way to block anonymous callers is to silence them.
- Go to Settings > Phone
- Scroll down and select Silence Unknown Callers
- Toggle it on. Calls from unknown numbers will be silenced and sent to voicemail
On Android:
On Android, the way to do it is to block anonymous calls. Here’s an example of how to do this on a Samsung Galaxy, though keep in mind the steps may be slightly different depending on which type of Android phone you have.
Settings may vary depending on your Android phone’s manufacturer.
- Open the Phone app
- Tap the More icon (three vertical dots) > Settings > Call blocking
- Turn on Block anonymous calls
If you have a different Android device and can’t find the “Block anonymous calls” feature, you can download an app instead that helps with this:
- Download and install the ShouldIAnswer? app from the Google Play Store.
- Open the app and configure it to block unknown and hidden numbers. This handy feature can help you maintain your privacy and avoid unwanted calls.

2) Download third-party apps
Speaking of the ShouldIAnswer app, if you don’t have that option and/or prefer not to use your phone’s built-in settings and want an extra layer of security, these other third-party apps can help block out anonymous callers:
TrapCall: TrapCall is available for both iOS and Android. It reveals the phone number of anonymous callers and provides options to block them. Just install from the App Store or Google Play then follow the steps to set up the app.
Truecaller: Truecaller is another option that’s similar to TrapCall in that it identifies phone numbers that appear “unknown” or “private” on your Caller ID, and it has features to then block them. Download the app from the App Store or Google Play and then configure the app.

3) Reach out to your phone carrier
Reaching out to your phone carrier is an effective step to combat spam calls. Many carriers offer services specifically designed to help customers manage and reduce unwanted calls. Whether you ring them up, contact them online or stop at your local phone store, they can help you.
BEWARE OF THE ‘SAY YES’ PHONE SCAM
How to trace anonymous calls
Sometimes, you want to know who is calling you so much. By unveiling who is behind the anonymous caller, you can find out if it’s actually a scammer or someone you know who is calling you over and over again to harass you. There are several reasons you may want to trace these calls. We won’t cover all those reasons here, but if you need help finding out who is actually calling you, try these methods below:
Dial *57: If you receive harassing calls, you can dial *57 after the call. This traces the call and logs it with your phone company, which can take action if needed.
Dial *69: This service redials the last number that called you, even if it was anonymous, allowing you to identify and block the number.

Invest in personal data removal services
In an era where our personal information is increasingly digitized, the risk of it being misused by scammers is ever-present. Investing in personal data removal services is one of the most proactive steps to protect yourself from spam calls and potential identity theft. These services work diligently to remove your personal information from public databases and websites often scraped by scammers to find their next target.
Why personal data removal services are worth considering
By removing your details from public view, you reduce the chances of being selected by a scammer in the first place. Also, knowing your information isn’t easily accessible gives you greater peace of mind. In addition, these services often allow you to control which information you want to be public and which you prefer to keep private.
How personal data removal services work
While no service promises to remove all your data from the internet, having a removal service is great if you want to constantly monitor and automate the process of continuously removing your information from hundreds of sites over a longer period. Remove your personal data from the internet with my top picks here.
By combining the use of personal data removal services with the methods outlined in this article to block and trace anonymous calls, you can significantly bolster your defenses against the ever-growing nuisance of spam calls.
Kurt’s key takeaways
Dealing with spam calls can be frustrating, but there are effective strategies to combat them. By utilizing your phone’s built-in features, downloading third-party apps and reaching out to your phone carrier, you can significantly reduce the number of unwanted calls.

Honda’s hybrid future starts with new Accord and RDX prototypes
Honda revealed prototypes of two new hybrid models, an Accord sedan and the Acura RDX SUV, during its annual business briefing this week, built on a platform that it says will begin launching next year. The RDX was announced earlier this year as Honda’s first SUV to feature the next-gen version of its two-motor hybrid system.
In March, Honda announced it would take a writedown of up to 2.5 trillion yen ($15.7 billion) on its EV investments. Now Honda says its EV-related losses will be “resolved” by 2029, and that it will reevaluate its EV plans in 2030.

New cancer tech sends chemo straight to tumors
NEWYou can now listen to Fox News articles!
Chemotherapy can save lives, but anyone who has watched a loved one go through it knows how hard it can be. The nausea. The exhaustion. The infections. The days when even getting off the couch feels like too much.
That happens because standard chemotherapy travels through the bloodstream. It attacks cancer cells but can also harm healthy cells along the way. For some pancreatic cancer patients, that approach may be changing.
A targeted drug-delivery system from RenovoRx is designed to send chemotherapy directly near the tumor instead of through the entire body. The system, called Trans-Arterial Micro-Perfusion, or TAMP, is being studied in a Phase III clinical trial for locally advanced pancreatic cancer.
For 83-year-old Hernando Salcedo, who had been left weak, nauseous and overwhelmed by standard chemotherapy, the trial offered something he desperately needed: a reason to hope. He enrolled at Miami Cancer Institute and soon began to feel the shift in his own body. His appetite started coming back. His energy improved. He felt more like himself. “The difference was tremendous,” Hernando said. “I completed eight sessions, one every 15 days, and I felt dramatically better than I did with the original chemotherapy.”

How the RenovoRx drug-delivery device works
RenovoRx’s platform uses the FDA-cleared RenovoCath device to deliver chemotherapy through a catheter placed in an artery near the tumor. A physician guides the catheter into position using X-ray imaging.
Shaun Bagai, CEO of RenovoRx, said the platform is designed to localize chemotherapy delivery near the tumor instead of relying on the drug to travel through the whole body.
“Once in position, two small balloons on the catheter are inflated, and the system is adjusted to isolate a targeted segment of artery adjacent to a tumor,” Bagai said. “The chemotherapy drug is then infused between the balloons, creating pressure to push the drug across the vessel wall and near the tumor, directly bathing the target tumor.”
That setup allows doctors to focus treatment in a specific area rather than exposing more of the body to chemotherapy. “The procedure itself is minimally invasive and is typically performed in an outpatient setting without the need for patients to be put under general anesthesia,” Bagai said.
For patients already dealing with pain, fatigue and fear, that outpatient approach may feel less overwhelming than a major hospital procedure.
How targeted chemotherapy for pancreatic cancer works
To understand why this approach matters, it helps to start with the problem doctors are trying to solve. Dr. Ripal Gandhi, a vascular interventional radiologist and interventional oncologist at Baptist Health Miami Cardiac & Vascular Institute and Miami Cancer Institute, explained why standard chemotherapy can be so hard on the body.
“With IV chemotherapy, the drug travels through the bloodstream, affecting both cancerous and healthy cells, which can lead to side effects,” Dr. Gandhi said. TAMP takes a more targeted route. A doctor places a catheter in an artery near the tumor, then delivers chemotherapy into that area instead of relying on the drug to circulate throughout the body.
Dr. Gandhi compared it to “a drip irrigation system for individual plants instead of watering an entire lawn.” For patients, that means doctors are trying to focus more of the treatment near the cancer while reducing how much chemotherapy reaches the rest of the body.
Why pancreatic cancer is so difficult to treat
Pancreatic cancer has a reputation for being one of the hardest cancers to fight, partly because the tumor itself can block treatment from working the way doctors want it to.
Dr. Gandhi said that creates a major challenge for standard IV chemotherapy. “Studies have shown that less than 10% of chemotherapy administered intravenously actually reaches tumor cells due to the few blood vessels in the tumor as well as dense fibrous stroma, which serves as a physical barrier in the tumor microenvironment,” Dr. Gandhi said.
That helps explain why targeted delivery could play an important role. TAMP sends the drug closer to the tumor rather than depending on the bloodstream to do all the work.
“This targeted approach via TAMP does not rely on chemotherapy circulating through the body to carry the drug to the tumor via tumor feeder vessels,” Dr. Gandhi said. “Trans-arterial micro-perfusion is a drug-delivery platform that delivers chemotherapy directly near the target tumor where it is needed most.”

Patient says targeted chemotherapy gave him hope
Hernando’s cancer journey began after he went to the doctor with a swollen stomach and hip pain. Doctors diagnosed him with locally advanced pancreatic cancer. When he started standard chemotherapy in August 2025, the side effects hit hard. “My body was going through an incredible amount of stress,” Hernando said. “My stomach was inflamed, I had persistent pain in my head, and I had almost no energy.”
He was also receiving chemotherapy and radiation at the same time. “It was a very difficult period, both physically and emotionally,” he said. “I remember feeling exhausted, overwhelmed and unsure of what the future would look like.”
When doctors presented the targeted treatment option, Hernando saw it as more than another medical procedure. “To me, it felt like a new opportunity to live,” he said. “It gave me hope at a time when my family and I really needed it.”
He credits Dr. Gandhi and the team at Miami Cancer Institute with helping him through it all. “From the beginning, he was honest, supportive and clear with my wife, my family and me,” Hernando said. “That meant everything.”
Fewer chemotherapy side effects changed daily life
“Before, I was losing weight, had no appetite and felt drained,” Hernando said. “After switching treatments, things began to change. I stopped losing weight, my appetite came back, my color improved and I had more energy.”
Cancer treatment can sometimes take over everyday life. When side effects ease, patients can get pieces of their normal life back. “After about eight weeks, we could see real progress,” Hernando said. “I was eating more, moving more and feeling excited about life again.”
One moment still stands out. Hernando was able to attend a family wedding and dance the entire night. “That moment meant everything to me,” he said. “After everything I had been through, being able to celebrate with my family in that way felt like a gift.” For Hernando, it was a chance to feel like himself again. “That night at the wedding, I was not thinking only about cancer or treatment,” Hernando said. “I was living.”
Early trial results show survival and quality-of-life signals
The early data from RenovoRx’s Phase III TIGeR-PaC trial suggest the targeted approach may offer both survival and tolerability benefits for some patients.
Dr. Gandhi said completed clinical studies with TAMP in pancreatic cancer showed “a potential for better outcomes and less side effects for patients.”
“In the initial interim analysis of the TIGeR-PaC clinical trial, there was a trend towards improved overall survival by 6 months and improvement in the progression free survival by 8.1 months with 65% fewer adverse events in the TAMP arm of the study,” Dr. Gandhi said.
Who may benefit from targeted chemotherapy delivery?
This approach isn’t for every pancreatic cancer patient. Doctors still need to look at the cancer stage, tumor location, treatment history and whether the cancer has spread.
Dr. Gandhi said Hernando was the kind of patient who could be a strong fit. “He is precisely the type of patient who would benefit best from this approach because he has a tumor which is too far advanced to be treated surgically, but it has not spread to other organs,” Dr. Gandhi said.
He also pointed to clinical trials as an important option for pancreatic cancer patients.”I discussed with him that the recommendation of the National Comprehensive Cancer Network is that the best management for pancreatic cancer patients is participation in a clinical trial whenever possible and he was an ideal candidate,” Dr. Gandhi said.
He went on to say that TAMP may be an option for patients who are not candidates for surgery, patients who have failed chemotherapy or patients who no longer want to continue IV chemotherapy because of side effects.
“TAMP can be used at any point within the treatment landscape, before, during or after other treatment modalities such as IV chemotherapy or radiation,” he said.

What comes next for RenovoRx’s cancer treatment platform
RenovoRx says the RenovoCath catheter is already FDA-cleared for general therapy and chemotherapy delivery. The company is also nearing the end of enrollment in its Phase III TIGeR-PaC trial.
That trial is evaluating intra-arterial gemcitabine (IAG) delivered through RenovoCath for locally advanced pancreatic cancer. Bagai said enrollment is expected to be completed in mid-2026, with final results expected in 2027.
“If positive, data generated from this trial could potentially support a new drug application for this combination product to the FDA for IAG,” Bagai said. RenovoRx also sees potential beyond pancreatic cancer. “The challenge we are addressing is not unique to pancreatic cancer,” Bagai said.
He said the platform could apply to other solid tumors with limited blood supply, including bile duct cancer, certain lung cancers and sarcomas. “The platform is designed to work with different types of therapies, not just one drug,” Bagai said. “That opens the door to future combinations and potential partnerships, with the goal of expanding options for patients who have limited treatment choices.”
What this means to you
If you or someone you love has pancreatic cancer, this story is worth paying attention to. Clinical trials can open up options when standard treatment feels too hard to tolerate or stops working.
Drug delivery matters, too. The medicine itself is only part of the story. Where it goes inside the body can affect side effects, energy levels and quality of life. Targeted chemotherapy delivery remains a specialized treatment approach. Some cancer centers may not offer it, and every diagnosis will not be a fit. Your care team can review imaging, staging, prior treatments and overall health to see whether it makes sense.
Start with direct questions. Ask whether a clinical trial makes sense. You can also ask about targeted delivery options or a second opinion from a pancreatic cancer specialist. Hernando’s advice to other patients is simple. “I would tell them not to lose hope and not to wait to ask questions,” he said.

Kurt’s key takeaways
Pancreatic cancer has a way of turning normal life upside down fast. One day, a family is making plans. The next, they are trying to understand scans, treatment choices and side effects that no one feels ready for. That is what makes Hernando’s story so powerful. The part that stays with you isn’t only the technology. It is the fact that he started eating again. He had more energy. He felt more like himself. And he got to dance at a wedding after wondering what the future would look like. The final Phase III trial results will be important. Doctors still need to see how widely this approach could help patients. But the promise is easy to understand. If chemotherapy can get closer to the tumor while taking less of a toll on the rest of the body, patients may get something that matters just as much as treatment itself: more good days.

Use this map to find the data centers in your backyard
When Oregon resident Isabelle Reksopuro heard Google was gobbling up public land to fuel its data centers in her home state, she didn’t initially know what to believe. “There’s a lot of misinformation about data centers,” she said. “Google has denied taking that land.”
Technically, she explains, The Dalles, a city near the Washington state border, sought to reclaim that land, “and Google is just a big, unnamed power user.” The city had in fact asked for ownership of a 150-acre portion of Mount Hood National Forest, claiming it needs access to Mount Hood’s watershed to meet municipal needs as its population — 16,010 as of the 2020 census — grows. But critics, including environmentalists, say the city is trying to secure more water for Google, which has a sprawling data center campus in The Dalles that already consumes about one-third of the city’s water supply.
This controversy made Reksopuro curious about the backlash to data centers being built in other communities. So Reksopuro, a student at the University of Washington who studies the connections between tech and public policy, decided to map it out. Using information collected by Epoch AI and data scraped from legislation on data centers, she built an interactive map tracking AI policy around the world. She designed it to be simple enough for anyone to use. “I wanted it to be something that my younger sisters could play through and explore to understand what are the data centers in the area and what’s actually being done about it,” Reksopuro said. She hoped to shift their opinions that way, “instead of like, through TikTok.”
Four times a day, the map searches for new sources and checks them against the existing database Reksopuro built out. “Once it does that, it will write a new summary, add it to the news feed, and populate it on the sidebar,” she said. “I wanted it to be self-updating, since I’m also a student.”
Reksopuro isn’t against data centers, but she thinks tech giants benefit from a lack of transparency around data center policies. “Right now, it’s this really opaque thing — and all of a sudden, there’s a facility,” she said. “I think that if people knew about data centers beforehand, it would give them leverage. They would be able to negotiate: ask for job training programs, tax revenue, environmental monitoring, things to improve their community.”
