Best Grills for 2025: We Tested Dozens to Find the Best Grill in Every Category

We use thermocouples linked to computer software to measure internal grill temperatures. Brian Bennett/CNET We test the main types of grills differently, but for most, we include a high-heat test like searing steak or grilling burgers, a medium, indirect heat test like grilling a whole chicken for more than an hour and a low-and-slow test with racks of ribs. With over 30 grills tested, we've got this down to a tee. To determine what should be the best outdoor barbecue grill, we collect data inc

Don't make this thermostat mistake during heatwave: 3 cost-saving tips from an expert

Maria Diaz/ZDNET Have you ever found yourself in a thermostat tug-of-war? One room feels like a sauna, another like an icebox, all while your trusty thermostat claims your home is at a perfectly average and comfortable 72 degrees? The truth is, you're probably not imagining things, and the culprit could be hanging right there on your wall. As it turns out, where your thermostat is located can make a world of difference to both your comfort and your energy bills. Also: How to disable ACR on yo

150 Million Americans Under Life-Threatening Heat Dome This Week

More than 150 million Americans from Texas to Maine are under extreme heat advisories as dangerously high temperatures bake the nation. Meteorologists warn that this heat dome could expand to affect an additional 20 million people by mid-week. In more than three dozen states from the Plains to New England, daytime temperatures could reach and exceed 100 degrees Fahrenheit (38 degrees Celsius) through at least Tuesday, AccuWeather reports. In an advisory issued Monday, June 23, the National Weat

Low-Temperature Additive Manufacturing of Glass

Researchers used the low-temperature additive manufacturing process to build the glass cups above. The optical behavior of the printed cups can be tailored by altering the chemical components of the inks. Additive manufacturing (3D printing) holds promise for fabricating complex glass structures that would be unattainable with traditional glass manufacturing techniques. Lincoln Laboratory’s innovative approach allows additive manufacturing of multimaterial glass items without the need for costl

HomeKit Weekly: Aqara’s W100 Climate Sensor brings precision monitoring and smart control to your HomeKit setup

Last night, I had forgotten to take my upstairs Nest off Eco mode, and I was shocked to see the difference in one of my son’s rooms based on my Nest Temperature Sensor. In my dream world, I’d have a variable system that could heat and cool rooms independently, but nevertheless, I didn’t buy bitcoin when it was $1, so I cannot afford that. With that being said, I do like having the knowledge of what’s happening in individual rooms and having that data in HomeKit. The new Aqara W100 Climate Sensor

Garmin’s new sleep tracker offers a week of battery life

Sleep tracking is nothing new in Garmin’s fitness watches, but the company’s latest wearable is a dedicated smart sleep band. The Index Sleep Monitor offers week-long battery life with continuous pulse ox tracking for monitoring your blood oxygen saturation while you sleep. Garmin’s tracker is worn on the upper arm — which should hopefully make it more comfortable — where it tracks a variety of metrics: skin temperature; light, deep and REM sleep stages; and variations in your heart rate and br

Alaska Issued Its First Heat Advisory, and Only 2% of Homes Have AC

Alaska got its first-ever heat advisory over the weekend, which is in effect until June 17. Over the last few days, temperatures in central Alaska have reached 86 degrees Fahrenheit (that's 30 Celsius). It's not as if Alaska never gets hot in the summer. However, as Jason Laney, a warning coordination meteorologist with the National Weather Service in Fairbanks, Alaska, told CNET, "The frequency with which the heat is coming up is starting to be a bit of a concern." This heat advisory seems pr

Best Kamado Grill for 2025

Testing kamado grills is an intense experience for a griller. It requires playing with fire (literally) and high temperatures, although in a controlled, responsible way. The most critical element to kamado's performance is heat, specifically temperature control and how well a grill holds to one temperature. To smoke meat low and slow, that magic number is 225℉. Good smokers, kamados or otherwise, will stick to this temp for as long as 12, 15 or 20 hours. This means the temperature gauge is key a

Alaska, Where Only 2% of Homes Have AC, Just Issued Its First Heat Advisory Ever

Alaska just crossed a first off its bucket list with the first-ever heat advisory for Sunday, June 15. Temperatures in central Alaska are expected to reach 86 degrees Fahrenheit (that's 30 Celsius) through the weekend and into the week of June 16. It's not as if Alaska never gets hot in the summer. However, as Jason Laney, a warning coordination meteorologist with the National Weather Service in Fairbanks, Alaska, told CNET, "The frequency with which the heat is coming up is starting to be a bi

Are Those Viral ‘Cooling Blankets’ for Real?

If you spend much time on the internet, you will see the same things pop up again and again. For me, it's these “cooling blankets” that people talk about on social media. I mean, it sounds great for summer—just like a blanket that warms you up but in reverse. Sadly, these products don’t do what they claim. They might be breathable so they don’t make you as hot as an ordinary blanket would, but you’d still be cooler with no blanket at all. However, there is hope. Someone has created a real cooli

I found a backdoor into my bed

What's an Eight Sleep? A little while ago I asked my infosec Twitter followers what IoT device in my house they thought I found a live AWS key in. (For those that don’t know, Amazon keys can be incredibly dangerous if exposed) Guesses ranged from a refrigerator to a bidet, but no one got it right. The right answer was my bed. I also found a backdoor into my bed, but more on that later. Security professionals are, in my experience, exhausted of things being connected to the internet
