Heating

Metallic theta-phase tantalum nitride exhibits an ultra-high thermal conductivity like no other material. This could be a desirable alternative to copper for computers and AI hardware, and even aerospace systems that need to run cool.

There's a lot of tech that solves problems that don't exist – however this isn't that. This mug from Feppo is one of those little products that makes things easier – especially if you get interrupted right when you've made yourself a coffee or tea.

Rising outdoor temperatures not only make nights uncomfortable but also deteriorate the quality of our sleep, according to a recent USC study. Researchers looked at the effects of heat on several aspects of sleep, and the results are sobering.

Ever since Xiaomi was founded, it's expanded from making smartphones to AR glasses, robots, and even cars. And just when you think the firm has created everything imaginable, it's introduced a smart blanket with voice control that also fights mites.

The Thermal Master P3 has emerged as one of the most promising compact heat-seeking cameras of 2025, managing to pack professional-level performance into a thumb-sized device for a third of the price of other imagers. There's a reason for the praise.

A study examining nearly 1,500 river sites in the US between 1980 and 2022 has shown that river heatwaves are happening up to four times faster than air heatwaves and lasting nearly twice as long. The finding has major implications for aquatic life.

Finland has inaugurated a giant sand battery this week in the southern town of Pornainen, where it'll take over heating duties from an old woodchip power plant. It's set to reduce carbon emissions from the local heating network by 70%.

A fan might feel like a lifeline in a heatwave, and for older adults it may be of some help – but not as much as it might seem. Using an electric fan in humid heat has a small benefit, but in hot and dry conditions, it can do more harm than good.

In a new study from the University of Oregon, scientists turned up the temperature to see which type of passive heat therapy packs the most health punch – hot baths, traditional saunas, or those fancy far-infrared saunas.

Nobody likes buildings that are too hot in the summer or too cold in the winter. That's where the FlectoLine facade comes in, as it uses two bio-inspired mechanisms to regulate how much solar thermal energy gets through a building's windows.

How's this for a set of promises? Flint Engineering claims its new, flat, thermal-transfer "IsoMat" can power entire homes, cut refrigerator energy consumption by 30%, and radically speed up EV charging while also extending battery life.

Imagine having a picture on your wall that completely changes when the room gets too warm. Engineers at MIT have created a new printing technology called Thermochromorph to make full-color images that switch in response to temperature.
