The Latest

Last year, Google released a niche feature in its experimental NotebookLM product that turned out to be a sleeper hit. You could upload any document to NotebookLM, and it would use AI to generate a two-person conversational podcast out of it. These aren't meant to be uploaded online for viewership, but for you to listen to as a learning ad.

The idea is that there are times when it's easier to understand a concept when two people are just casually conversing about it. If that sounds appealing to you, good news: you no longer need to dive into the unfamiliar NotebookLM interface to try it out. Google's AI-generated podcasts, called Audio Overviews, are now available for free directly in the Gemini app and website. And now that Audio Overviews are integrated directly into Gemini, you can even use Gemini's own Deep Research reports as sources for your podcast.

Personally, I've found it useful to first prompt Gemini to create a Deep Research report on a topic, then directly generate an Audio Overview from it (skipping past having to read it myself).

Generate and download podcasts on any topic

To get started, use the Gemini website or the Gemini app. To upload your own document or slide show, click the Plus button and add in your desired source file. As soon as the file is processed, you'll see a button for Generate Audio Overview.

Press the button and wait for Gemini to begin its work. It can take anywhere between 3–5 minutes to generate your podcast audio, depending on the depth of the material.

Alternatively, you can prompt Gemini to create a report for you using the Deep Research option below the text box. Here, too, you'll have to wait a couple of minutes until the research is ready. Then, open the Deep Research document, click the down-arrow button, and then use the Generate Audio Overview button. You can also just enter "Generate Audio Overview" in the text box.

When the processing is done, you'll get a notification from the Gemini website or the app. You'll now see a player in the chat box. Hit the Play button to start playback, and use the seek bar to jump to any point in the recording. Yes, there's speed control too, but you can only increase the playback speed up to 1.5x.

I got 10 minutes of podcast overview from a 12-page document, so the detail isn't bad. If you don't want to listen to your podcast right away, or if you'd like to share it, you can also download the audio for offline payback. Click the three-dot menu button in the audio player and choose the Download option.

From here, you can also choose the Share conversation option to share your Gemini chat and recording using a link.

And while you're in Gemini, you might want to try creating your own custom AI Bots, called Gems, since those are now free for everyone to use.

You may have seen a headline this week imply that OneNote, the extremely popular note-taking application from Microsoft, is shutting down. That's not the case—only a specific version of OneNote, named "OneNote for Windows 10," is shutting down.

What's this mean? If you don't use Windows, this news doesn't affect you. If you do use Windows, and your version of OneNote does not say "OneNote for Windows 10" at the top of the window, this news doesn't affect you. If your version of OneNote does say "OneNote for Windows 10" at the top of the window, then this news is relevant: The version of OneNote you're currently using will be discontinued on Oct. 14. You can download the desktop version of OneNote for free, though, and all of your notes will sync over.

It's worth noting that the desktop version of OneNote offers features that OneNote for Windows 10 never did—it can save your notebooks offline, for example, meaning you don't need a OneDrive account to use the application. And the shutdown isn't a surprise by any means—Microsoft announced this transition would happen years ago.

Still, not everyone is happy about this. OneNote for Windows 10 was built to work well on mobile devices and, to this day, some users prefer it for touch screen Windows devices. I tested both versions while writing and regularly updating the OneNote review for PCMag and I personally find the desktop version more complete, but I understand why some might prefer the "for Windows 10" version—it's clean, fast, and does what most people want.

You can still, as of this writing, download OneNote for Windows 10 at this link. Microsoft advises you not to, and plans to show pop-ups and even intentionally slow down syncing speed in order to persuade people to switch. Support ends completely in October, after which there will be no security updates and, if history is any guide, functionality will likely slowly break.

So, if you're using OneNote for Windows 10, it's time to figure out what you want to use for note-taking going forward. I'd recommend downloading and trying the desktop version of OneNote first. If you're not a fan, there are other note-taking applications out there: Obsidian, which I've written about, can even import your notes from OneNote.

As we appear to be living in an age of perpetually rising grocery prices, we're all looking for ways to lower our food bills. Considering the average spend on groceriesis over $500 every month, I'm all open to suggestions. Extreme couponing? Tell me more. Intermittent fasting? Sounds doable. Ugly produce? Bring it on!

Spending money to save money? How does that work?

Kitchen tools like bread makers or chest freezers tend to pay for themselves over time, but often come with a hefty upfront cost. Yet there are some inexpensive gadgets that don’t require a big investment but which can trim your grocery bills significantly. Here are eight of them.

Bottle connectors

There’s nothing more frustrating than paying for a bottle of something and leaving a bunch of it in the bottle because physics refuses to release it. But if you throw away bottles of stuff—whether it’s condiments, shampoo, or anything else you pick up at the grocery store—with product still trapped in there, you’re throwing away money. Instead, pick up a bottle connector (which will let you transfer the dregs of an old bottle to a new one), a zero-waste cap (which will use gravity to help you use every drop of something in the bottle), or a bottle scraper of some kind to get every bit out of the bottle. It’s difficult to quantify how much money you can save by doing all these things, but it’s not nothing.

A food vacuum sealer

A food vacuum sealer isn’t the cheapest option; while you can find sealers for about $10, that could definitely be a penny-wise, pound-foolish kind of decision. But an initial investment of anywhere from $40 to $100 will save you money in several ways:

  • Reduce waste. Vacuum-sealing your leftovers and overflow ingredients will keep them fresher far longer.

  • Make bulk buying pay. Buying in bulk usually reduces your per-unit costs—but only if you can actually use what you buy. Vacuum-sealing makes it easier to buy something like meat or fish in bulk and keep it fresh long enough to actually eat. Additionally, if you happen upon a terrific sale on something perishable, you can make an unusually large purchase work economically by sealing and freezing most of it.

Herb keepers

If you cook with a lot of fresh herbs, a herb keeper can help keep them fresh for more than a week longer than if you just stick them in the crisper (or in a plastic bag, where all herbs go to wilt). That means you can actually use them in multiple meals and buy less of them overall.

Produce savers

Buying fresh produce is often an exercise in expensive frustration. You pay for a bunch of apples, and some of them are already rotting seemingly before you even get them home from the store, and the rest don’t fare well no matter where you store them. You might be one of those folks who thrills at turning black bananas into banana bread and soft apples into pies, but it would be better if everything just lasted longer. That’s where products like GreenBags and the BlueApple Produce Saver come in. Both extend the life of fresh produce by days, giving you extra time to use up what you buy and improving the taste and overall experience of the produce you’re eating. Over time they’ll pay for themselves in fresher fruits and veg, and lower grocery bills.

A cheese grater

You might not think of a cheese grater as a gadget, but tell that to the people who lived before its invention. Buying your cheese pre-grated will definitely save you money (and give you a better cheese experience, as pre-grated cheese usually is coated with a bunch of stabilizers and preservatives in it to keep it from clumping). Block cheese will almost always be cheaper than pre-grated cheese, so aside from the better eating and cooking experience, grating your own cheese will pay for the grater over time, and then some.

Silicone stretch lids

If you use foil or plastic wrap on a regular basis to cover bowls, old plastic storage tubs that have lost their lids, or pots straight off the stove (smash cut to your eating directly from the saucepan with a spoon later that night), you’re paying money every time you tear off a sheet. Instead, use these stretchy silicone lids. They’ll fit just about any bowl or tub you’ve got and will keep their contents nice and fresh, with an airtight seal that’s almost certainly better than that mangled lump of aluminum foil you were going to use. One note: You shouldn’t use these to leave extra canned goods in the can. Yes, the lid will cover and seal the can effectively, but once opened, your food will start reacting to the metal of the can, which can degrade the flavor and kickstart bacteria growth.

Reusable paper towels

If you’re using a lot of disposable stuff from the grocery store, a great way to save money is to switch to reusable, washable versions. Makeup removal pads and paper towels (which can also be used as casual napkins) are two easy switches. Rayon paper towels made from bamboo are sustainable and can be used about 50 times. In the meantime, not buying a new supply every week or so will definitely save you some cash—have you seen what Target wants for a thing of paper towels these days?

Dryer balls

If you use dryer sheets when you do laundry, you can probably reduce your shopping bills by switching to wool dryer balls. Dryer sheets range in price from about four cents per sheet on the low end to about ten cents a sheet (mainly for specialty sheets, like the ones intended for homes with a lot of pet fur). Wool dryer balls help reduce drying time, wrinkles, and static cling and are reusable (up to about 1,000 times). So a six-pack of dryer balls will get you at least 6,000 loads of laundry for about $10, as opposed to $240 for dryer sheets. Even if you wash large loads and use 2-3 balls per load, you’ll still seeing significant savings over dryer sheets.

Companies like Apple have their own ecosystems, where it's easier to interact with other devices from the same company. For example, it's trivially easy to transfer photos from one iPhone to another, or to share a Wi-Fi password between iPhones with one tap. The same goes for a hotspot as well. You can start using your iPhone's internet connection on your iPad or Mac, without even lifting your iPhone. Android, unfortunately, mostly lacks this level of cross device integration.

Samsung and Pixel devices do offer some exceptions, but usually only with other Samsung or Google devices, respectively. Now, though, a formerly Pixel-exclusive tethering feature named Instant Hotspot is coming to Samsung devices, starting with the Galaxy S25 series.

How Instant Hotspot works

Instant Hotspot works with any compatible Android and Chromebook device, and they don't have to be from the same manufacturer. For example, you can use this feature to enable internet connection on a Chromebook or a Pixel tablet, or a secondary Android phone without a SIM connection. And all that can happen in a single tap.

When the feature is enabled, you'll see a notification on the offline device, asking if you want to connect to the your online gadget and create a hotspot. The catch is that this only works for devices that are registered to your Google account, but it should make sharing data much simpler.

How to enable and use Instant Hotspot on the Samsung Galaxy S25

Instant Hotspot is built on top of Android's Cross-Device Services feature that was released last year. It was available on Pixel phones first, but finally other manufacturers are starting to integrate. Samsung's Galaxy S25 series devices are confirmed to be some of the first to get access to this feature, with the One UI 7.0 update. According to user reports seen by Android Authority, older devices with the One UI 7 update are starting to see this feature, too.

To enable the Cross-Device Services feature, go to Settings > Google > Cross-Device Services. Tap Next to set up the feature. Then, tap OK to join a group of your devices that are all connected to the same Google account.

Now, you'll see settings for two new features, Call Casting and Internet Sharing. Make sure that both are enabled.

Once that's done, you're off to the races. When your Galaxy S25 is near another Android phone, tablet, or Chromebook that's offline and in your Google account group, your device will get a gentle notification asking if you'd like to use your Galaxy S25's internet connection with it. Just tap the Connect button to create a temporary hotspot from your phone.

If you don't see the notification, you can also manually browse the available Wi-Fi networks. You'll find the Galaxy S25 listed right up top.

When it comes to having the hottest, crispiest snacks at the ready, I’ve always had your best interest in mind. While any air fryer is better than no air fryer, in a perfect world the best air fryer would be available to us all at an affordable price. Well folks, my favorite air fryer is 39% off for Amazon’s Big Spring Sale and it’s a deal worth jumping on. 

The Cuisinart Air Fryer Toaster Oven is $139.95 right now, compared to its usual $229.95, and while it’s not cheap per se, I would say it dips down into a much lower price bracket for sure. If you were looking for air fryers in the $100 to $150 range, then the Cuisinart is worth considering.

I reviewed the Cuisinart Air Fryer Toaster Oven late last year and I was completely won over by how quiet it was. Convection ovens across the board are effective cooking machines, so I believe it’s the side benefits that make an air fryer right or wrong for a person—like, do you need double baskets? Or do you need a travel air fryer? There are many things to consider. The cherry on top is that this very air fryer also became my top pick for Best Overall Air Fryer when considering size, ease of use, price, and other features (like window or basket model). 

My favorite features of the Cuisinart Air Fryer Toaster Oven are the simple operating controls using turning knobs instead of digital buttons that might have you clicking 25 times just to increase the time, the ample interior space, and the sweet, sweet (near) silence of the convection fan.

In a habitat like Brooklyn (near an above-ground subway train in a neighborhood that loves to honk horns for all communication) an air fryer as quiet as this is like a vacation. A vacation that gives you crisp tater tots at the end. Whether you have a new baby that wakes up at a pin’s drop, or you simply enjoy a quiet atmosphere, you can have peace and the perks of a high-quality air fryer for an excellent price right now.

Another day, another security breach, but this time it's going down in the group chat. On Monday, The Atlantic's editor-in-chief, Jeffrey Goldberg, reported that he had been added to a Signal conversation with Trump administration officials—including Defense Secretary Pete Hegseth, Vice President JD Vance, Secretary of State Marco Rubio, and National Security Advisor Michael Waltz—who were discussing highly sensitive "operational details" about impending attacks in Yemen.

Signal is a secure messaging app, but as a publicly available service, it's not meant for coordinating military operations (the U.S. government doesn't allow its use to communicate classified information). Here's what Signal is great for—and the limits to the privacy it ensures.

When you should use Signal

Signal is a free, open-source messaging app with end-to-end encryption, allowing users to keep conversations (including text, images, audio and video messages, and calls) private and safe. It's one of our top picks for secure communication, and its privacy and security settings and open-source protocol are lauded by the Electronic Frontier Foundation as well as many data security experts.

In addition to end-to-end encryption, Signal has a disappearing messages function, which deletes chats after a set period of time, as well as features like photo blurring, hiding your phone number by default, and other security settings to protect your identity and your data.

All of these factors make Signal an excellent choice for communication you want to keep private, whether you're transmitting personal or sensitive information or are engaging in activism or otherwise want to know that no one but you and the intended recipient can read your messages. If you're an iPhone user, you can make Signal your device's default messaging app. (Signal used to support SMS/MMS on Android, allowing you to use it as your default messenger, but removed that functionality in 2022.) But there's still a couple of sticking points to keep in mind.

Signal still has privacy risks

While Signal is an excellent tool for encrypted communication, it doesn't guarantee absolute privacy for classified information, such as that related to matters of national security.

As recent events show, users can be added to group chats—mistakenly or on purpose—leaving open the possibility that your messages will be exposed to someone not meant to see them. You should verify the identity of everyone included your threads before sending sensitive information to them, and consider utilizing Signal's group chat settings to require approval of new members or restrict who can add members to the thread.

If private information is being shared, you can also verify a contact's safety number to ensure they are who you think they are.

But even if you maximize all of Signal's security settings, the mobile device you're using could be compromised by spyware, as Apple has warned users in more than 150 countries. These campaigns attempt to install invasive malware on smartphones to capture users' location, data, and activity—defeating any encryption benefit Signal offers in the process. Bad actors are most likely to target high-profile politicians, activists, journalists, and others who have access to classified or sensitive information.

Additionally, Signal can also be downloaded and accessed across multiple devices, including a desktop app, where data may be stored less securely or compromised by malware.

Finally, there's always the possibility that your device could simply be swiped, leaving your data open to whoever can unlock it (a good reason to enable disappearing messages).

With that in mind, while installing Signal is a good place to start, it shouldn't be the entirety of your privacy routine. If you have an iPhone, here are a few additional steps you can take to keep your data secure—perhaps our government officials could benefit from going through this checklist, too.

This week, there has been a lot of chatter in the weirder parts of the online world about the supposed discovery of a hidden complex of underground chambers beneath the Great Pyramids of Giza in Egypt. It seems a team of researchers announced they'd used SAR (Synthetic Aperture Radar) to reveal a number of underground buildings beneath the Khafre Pyramid.

This discovery could offer proof the ancient Egyptian civilization was far more advanced than is generally believed, and possessed technology that rivals our own. It could change everything we think we know about humanity itself! In other words, big if true. 

Spoiler: It's not true though. All signs point to the “discovery” being an especially elaborate example of pyramid-based misinformation, another in a long string of untrue claims about the ancient Egyptian monuments that never seems to end, because cranks just love making up stories about the pyramids.

What was supposedly discovered under the Great Pyramids? 

I gotta give the “researchers” behind this "discovery" an A for effort. The supposed results of the SAR-based research were shared with the world at a press conference held in Bologna, Italy, on March 15, and it all looks very official. Here’s a video of the event:

It’s in Italian, and there are no English translation available yet, so I’m relying on other people’s translation work, but the gist is that the GIZA Project involves a team of “researchers, historians, archaeologists, and technologists” using high tech imaging techniques. They say they've discovered five identical structures connected by “geometric pathways,” eight “structures resembling vertical wells, surrounded by descending spiral pathways,” and “two large cubic structures measuring approximately 80 meters per side at a depth of 648 meters” at the site of the Great Pyramids.

The conference featured multimedia detailing the supposed discoveries, charts and graphs, people acting very serious, and all sorts of “this is real science!” frippery, so as you’d expect, the easily fooled were fooled, easily. Alex Jones touted this as “greatest archeological find in HISTORY.” Others wondered if the structures under the pyramids are part of a massive power plant, or maybe an ancient super weapon, or part of the “legendary Amenti,” a subterranean city “linked to ‘universal knowledge of humankind and its ultimate spiritual transformation.’”

Or maybe the entire thing is nonsense and nobody discovered shit.  

Where does this new pyramid research come from?

Many of the claims made in the press conference aren’t based on any published research, so it’s just people saying stuff in Italian, but the facts that can be checked are largely based on a research paper published in the journal Remote Sensing in 2022. Corrado Malanga and Filippo Biondi are listed at the top of a paper named “Synthetic Aperture Radar Doppler Tomography Reveals Details of Undiscovered High-Resolution Internal Structure of the Great Pyramid of Giza.” It’s a dense read, full of technical information and equations like this:

Math equations
Credit: Remote Sensing

Don't bother plowing through it and checking the math: The paper’s most notable feature is that it’s not peer reviewed, so you can safely ignore it for now. No independent expert in imaging has looked at this paper in a serious way to determine if SAR could even work like this, and radar experts doubt you could penetrate 648 meters through limestone bedrock. No archeologists have substantiated these claims. Neither have any historians or sociologists. Bottom line: without peer review, there’s no reason to take this paper more seriously than you’d take wild claims made by a random person on a bus. 

And that’s the generous interpretation. A less generous view is expressed by established Egyptologist Dr. Zahi Hawass, who wrote on his Facebook:

All this information is completely wrong and has absolutely no scientific basis… the claim that a radar was used inside the pyramid is false…These people who announced this wrong information, they used techniques that are not approved nor validated, the details announced would never have been seen by using this technique.

Until actual scientists have a look at this research (and I wouldn’t hold my breath) it’s safe to file it under “pyramid misinformation,” a hearty mind-weed that’s been around forever and seems impossible to kill. But pyramid myths are at least fun, so here are some other common things people get wrong about them.

Myth: The pyramids were built by slaves or aliens

Conspiracy theorists often argue that “mainstream” archeologists and historians shouldn't be believed because they have a compelling interest in rejecting new ideas to maintain the academic status quo. But until relatively recently, many historians, archeologists, and most of the general public believed the pyramids were built by slave labor—specifically by the Jews. This is probably because Egyptians enslaving Jews is mentioned in the Bible (though the pyramids are not) and because Greek historian Herodotu reported that slaves were building the pyramids when he visited in 450 B.C. 

Even though it challenged the orthodoxy of their field of study, archeologists uncovered new evidence and reexamined existing evidence to change the conventional wisdom. It turns out the pyramids were not built by slave labor, at least not as we understand slavery today. Instead, the archeological evidence suggests the the pyramids were built by around 20,000 Egyptians who were paid, well-fed, had the equivalent of medical care, worked seasonally, and even left graffiti behind bragging about how awesome their work crew was compared to the others. This evidence also helps us cross "aliens" off the list of potential pyramid-makers. (Giants didn’t build the pyramids either.)

Myth: Ancient people could not have moved the pyramids' heavy stones

We don’t know exactly how the stones they used to build the pyramids were moved into place, but we have evidence that the ancient Egyptians loaded the stones on barges, floated them down the Nile, then dragged them on sledges over pathways they’d made of of slaked lime or tafla, probably using water to reduce friction. No advanced technology or extraterrestrial help was needed, and there’s no evidence at all to suggest they were employed. A lot of people working together can accomplish great things, especially if they have all been given enough beer.

Myth: Pyramids existing independently in different prehistoric societies is evidence of a common culture

From Mayan pyramids in Central America to Angkor Wat in Cambodia, many disparate ancient civilizations built pyramid-shaped monuments, leading some to suggest they had a common culture or there was an ancient means of communication between groups. Some think there’s something inherently “spiritual” in a pyramid’s shape.

While some ancient civilizations did communicate and trade with each other, the main reason pyramids all look similar is the same reason sand castles all have a vaguely pyramidal shape: It's the most stable way to build anything upwards, no matter where your ancient civilization is located. 

Plot-twist: A real anomaly was discovered near the Great Pyramid

This news was not breathlessly tweeted by Alex Jones, but in 2024, real scientists announced they’d discovered a mysterious structure under the royal graveyard near the Great Pyramid of Giza.

Using ground penetrating RADAR and electrical resistivity tomography, researchers from Higashi Nippon International University and other institutions identified an L-shaped structure that is about 33 feet long and is buried 6.5 feet deep. Maybe that's not as impressive as a city-sized proto-battery under hundreds of meters of limestone, but beneath that there's a "highly resistive anomaly!"

It's totally unknown, so you can pretend it's an alien spaceship if you want, but scientists think it's probably a mix of sand and gravel or “an air void.” It’s not an underground city or the remains of an ancient battery, but at least it’s real.
