‘People Are So Proud of This’: How River and Lake Water Is Cooling Buildings

“In the old days, it was more like a luxury project,” says Deo de Klerk, team lead for heating and cooling solutions at the Dutch energy firm Eneco. Today, his company’s clients increasingly ask for district cooling as well as district heating systems. Eneco has 33 heating and cooling projects under construction. In Rotterdam, Netherlands, one of the company’s installations helps to cool buildings, including apartment blocks, police offices, a theater and restaurants, using water from the River

Liquid Cooling Exhibits

Hot Chips doesn’t just consist of presentations on hardware architecture, although those are the core of what Hot Chips is about. The conference also features stands where various companies show off their developments, and that’s not restricted to chips. Some of those showed off interesting liquid cooling components, particularly in cold plate design. Water Jets Many of the waterblocks on display use microjets, rather than microfin arrays. Water flows through a manifold at the top of the block

Noctua’s 3D-printed mod singlehandedly makes the Framework Desktop run quieter

Despite its lack of upgradeable system memory, Framework has tried to make its Framework Desktop a welcoming platform for upgraders and modders, releasing 3D-printable versions of a few case parts and generally sticking to standard-sized parts and standard connectors. Often, it's independent creators who are making the weirdest and most interesting mods for Framework's devices, but PC cooling company Noctua has just announced what amounts to a fairly major cooling upgrade for the Framework Desk

The Best Cooling Sheets (2025): Brooklinen, Slumber Cloud, Buffy

There's a lot of terminology thrown around in the world of cooling sheets and cooling mattresses. Temperature regulating! Airflow! Moisture wicking! Phase-change material! Most of the time, these features come back to how breathable the sheets are. Breathability means moisture can better evaporate, and “temperature-regulating” usually means the sheets are breathable enough to release the heat and moisture from your body. What makes sheets breathable? Cotton, flax linen, and bamboo have great br

A dedicated skin-to-brain circuit for cool sensation in mice

Researchers at the University of Michigan have illuminated a complete sensory pathway showing how the skin communicates the temperature of its surroundings to the brain. This discovery, believed to be the first of its kind, reveals that cool temperatures get their own pathway, indicating that evolution has created different circuits for hot and cold temperatures. This creates an elegant solution for ensuring precise thermal perception and appropriate behavioral responses to environmental change

Jack Wallen / Elyse Betters Picaro / ZDNET Have you ever been relaxing when, out of nowhere, your phone blows up with notifications? I've been there too many times, which led me to keep my phone on silent mode 24/7. Then Google teased a new feature in Android 15 called Notification Cooldown that promised to change everything. Notification Cooldown didn't exactly hit the mark in Android 15, but it has made a comeback in the latest iteration (Android 16) to ensure that it works exactly as expect

Phones with both a cooling fan and water resistance don’t exist, until now

Electric Cooler vs. Ice Cooler: I Camped With Anker's Solix EverFrost 2 and an RTIC Ice Box to See Which Is Better

Keeping drinks and food cold while camping can be a challenge, especially in the summer. Though a portable power station hooked up to a minifridge can help, it's not the most power-efficient option compared with either an electric cooler or a traditional icebox. I set out to test a "regular" icebox-style cooler -- specifically, RTIC's icebox -- against Anker's new Solix EverFrost 2 to see how it would fare in real-world use against the best coolers on the market.

Bedsure's Bamboo Cooling Sheets Are Silky Soft, Durable, and Cheap

I’ve met many supposedly “cooling” sheets in my time as a mattress and bedding tester, and I have been disappointed more often than not. A cooling mattress can’t do all the heavy lifting with temperature regulation, and I’ll forever emphasize that your choice of bedding matters just as much—which is why I'm an unapologetic sheet snob. Which brings me to Bedsure, a brand I stumbled across on Amazon in a last-ditch effort to find some decent sheets when mine bit the dust (rather, my dogs bit holes

MacPaint Art from the Mid-80s Still Looks Great Today

MacPaint Art From The Mid-80s Still Looks Great Today I really enjoyed browsing the BMUG's CD-ROM and discovering earliy 80s art made in MacPaint, so I browsed all 18,000+ MacPaint images on Discmaster to see what gems I can unearth. Here is some what I found - I've got so many more cool icons/smaller drawings kept aside for the next time I'm bored and feel like making a blog post.
