When Apple updates its iPhone operating system, it also updates many of the Apple apps that run on top of it too—and the big iOS 26 update that was pushed out to millions of handsets in September comes with a useful new feature for Apple Maps. The feature is called Visited Places, and as you might guess from the name, it keeps track of the locations you’ve been to. Initially, this might seem like a bit of a privacy nightmare, but all this information is end-to-end…

Their very name references their devastating decline—they were the “right” whales for whalers to target, since the animals floated after being killed. Today, their biggest threats are ship collisions and getting tangled in fishing gear. For once, however, there’s good news from the marine conservation community. Estimates for North Atlantic right whale populations are slowly increasing, according to a New England Aquarium statement. Researchers at the North Atlantic Right Whale Consortium,…
The new Nest Cam Indoor and Nest Cam Outdoor boast the easiest setup experience I’ve encountered. Simply plug them in (the Nest Cam Indoor comes with a 10-foot USB-C cable, the Nest Cam Outdoor has an 18-foot weatherproof cable), scan the QR code sticker on the front of each camera with the Google Home app, connect to Wi-Fi, and you’re up and running in no time (both support 2.4-GHz and 5-GHz bands). The elegant magnetic mount for the Nest Cam Outdoor needs a couple of screws, while my Nest Cam Indoor is perched neatly on a shelf.While Google has lagged…
Like many first-time mothers, Lisette Lopez-Rose thought childbirth would usher in a time of joy. Instead, she had panic attacks as she imagined that something bad was going to happen to her baby, and she felt weighed down by a sadness that wouldn’t lift. The San Francisco Bay Area mother knew her extreme emotions weren’t normal, but she was afraid to tell her obstetrician. What if they took her baby away?At about six months postpartum, she discovered an online network of women with similar experiences and ultimately opened up to her primary care doctor. “About two months after I started…
By default, Google manages your encryption key, but it allows you to set up on-device encryption, which functions similarly to a zero-knowledge architecture. Your passwords are encrypted before being saved on your device, and you manage the key. Regardless of how the encryption works, Google uses AES, which is still the gold standard for security among password managers.It was trivial to decrypt Chrome passwords previously, requiring little more than a Python script and knowledge of where the files are stored. But even there, Google has pushed the security bar up. App-bound encryption has invalidated those methods, and cracking passwords is…

The Thuma Hybrid offers three firmness options: Plush, Medium, and Firm. I chose Medium because my partner and I (mainly me) fluctuate between different sleeping positions. We both are side sleepers for the most part, but often, I revert to being a stomach sleeper sometime in the night. Both of these sleeping positions require more lumbar support to prevent back pain. But from the first night of testing, it was undeniable that this mattress had a firmer feel. In my experience, beds with medium firmness typically range between a 5 and 6.5 on a scale of 10, with 10 being…
Archaeologists have discovered an unusual circular stone grave in southern Germany. Dating to the Roman Empire, the large tomb was completely empty — and it may have been erected as a monument to honor someone buried elsewhere.”The tomb was both a place of remembrance and an expression of social status,” Mathias Pfeil, curator general of the Bavarian State Office for Monument Preservation, said in a translated statement. “We hadn’t expected to discover a funerary monument of this age and size here.”The tomb was discovered during construction work in the fall of 2024 in the village of Wolkertshofen, located in the…
The Top 5 GoPro Hero Cameras ComparedGoPros to AvoidGoPro doesn’t sell anything older than the Hero 12, but there are plenty of Hero 11s and even Hero 10s out there for sale on the internet. We suggest avoiding them. They may work fine, but modern accessories designed for later models won’t work, and these cameras have likely been through the wringer. (They are action cameras, after all.)GoProHero 11 BlackGoPro no longer sells the Hero 11, but it’s still commonly available on Amazon and other retailers. Unfortunately it’s usually the same price as the Hero 12 (around $300) and therefore not…
