Cooling

The heat from within your laptop disperses slowly, like ripples in a pond. What if we could turn that heat into channeled waves that travel away from the source up to a hundred times faster? Researchers are giving it a go – with crystals.

Under specific conditions, lasers can cool things down – and that might just be what we need to tackle way-too-toasty data centers. A new technology called laser-based photonic cooling can target tiny hotspots on chips to zap heat away.

Oyster mushrooms and bits of bamboo sound more at home on a Chinese menu than stuck to the wall, but scientists have used this mix to make aesthetically pleasing tiles with bumps and textures that help regulate temperature much like elephant skin does.

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.

Although sunscreen does help protect our skin from the sun's harmful UV rays, it isn't designed to keep that skin cool. An experimental new sunscreen does that very thing, however, while maintaining an SPF rating of about 50.

Cranking up the air conditioner keeps buildings cool, but it guzzles energy. Passive materials can regulate temperatures more efficiently, and now scientists have developed a new coating that keeps glass much cooler, while still being transparent.

Although hot tubs may get all the glory, cold-plunge tubs are the ones that really help reduce muscle inflammation and soreness. The Snowcap tub makes that process more doable than ever, by chilling water without using any ice or refrigerants.

We're caught in a vicious circle of facing increasing temperatures across the planet, and combating that with air conditioning – which in turn causes global warming. A problem worth throwing a whole lot of science at, if there ever was one.

When it comes to keeping cool on hot days, it's not so much a matter of wearing less clothing as it is a matter of wearing the right clothing. A new fabric coating could help in that regard, and it's essentially made of chalk.

Nissan has demonstrated a new automotive paint that can drastically cool a vehicle parked in direct sunshine. Tests have shown that treated cars stay up to 21.6 °F (12 °C) cooler than untreated cars parked side by side.

Artificial-turf sports fields may be more durable than those covered in grass, but they also get very hot during warm weather. Scientists have devised a method of cooling them – and the cities they're in – using rainwater stored beneath the turf.

Whether you're working outdoors or just taking a leisurely stroll, keeping your cool on a hot and sticky summer day can be a struggle. But a new Kickstarter campaign may have just the thing for a quick but lasting cooldown.
