In a warming world, air conditioning is a necessary evil. Or is it?

“As carbon emissions push Earth’s average temperature to new heights and usher in unprecedented heat waves, humanity’s reliance on air conditioning is growing. The trouble is, AC consumes massive amounts of energy and — due to the world’s continued reliance on fossil fuels — emits lots of carbon. Overcoming this feedback loop presents a significant engineering challenge that is becoming increasingly urgent as the world warms. Enter passive cooling: non-mechanical approaches to lowering indoor temperatures. This certainly isn’t a new concept. Passive cooling relies on architectural techniques used for centuries in hotter regions, though scientists are advancing these methods with modern materials and technologies. Several have made impressive strides in recent years, but each strategy comes with its own benefits, tradeoffs, and limitations.”

Meet the guy who’s been solving your Mac problems since 2010 without you knowing it.

Yanis Zafiropulos has spent sixteen years building Mac apps nobody asked for but everybody eventually needs, tools with names like Squeezer, DMG Wizard, and Web2Mac that each solve one weirdly specific problem better than anything else out there. Now, all 27 of them, covering everything from font management to Wi-Fi diagnostics to batch file renaming, are bundled into one lifetime license. The annoying, specific Mac headache you haven’t had yet already has a fix waiting in here. [Ad]

Gene-edited beagles may offer a future option for people with dog allergies

“Matt Walker couldn’t pet a dog without sneezing — until he and other scientists used a gene editing technique to produce a hypoallergenic beagle named Bailey. Now, he can feed Bailey spoons of peanut butter while she lies on his lap and play fetch with her in Central Park. His allergies didn’t go away: Bailey’s saliva and hair no longer contain a key allergy-causing protein…”

Mars dust is toxic. How will future astronauts deal with it?

“Planting boots on Mars is hard enough. But getting ‘breathing room’ on the Red Planet without inhaling toxic dust is yet another issue. Given NASA’s plans to eventually put astronauts on the Red Planet, the agency assembled a Martian Dust Limit Working Group earlier this year to review what’s known and unknown about the toxicological hazard to human crews from exposure to Mars dust. The ultimate goal was to establish a permissible exposure limit for humans on the Red Planet by compiling a comprehensive set of expert perspectives regarding Martian dust toxicology, exposure pathways, and mitigation strategies.”

Why settle for one AI? Here, have ’em all.

Picking just one AI model is like only ever eating one type of cuisine — technically fine, but deeply sad. ChatPlayground AI throws GPT-4, Claude, Gemini, and a murderers’ row of other models into one dashboard, so you can actually see which one handles your weird, specific use case best. Writers, devs, researchers, and chronically online overthinkers have been quietly using this thing to run circles around people still on a single-model diet. One lifetime payment gets you access permanently. [Ad]

The body’s hidden light detectors

“When sunlight hits an octopus, it can trigger a swift color change and instant camouflage, thanks to light-sensitive molecules embedded in the creature’s skin. When sunlight falls on a bird’s skull, similar compounds deep in the animal’s brain register changes in day length and help drive decisions on when to mate or migrate. Photosensitive proteins called opsins that respond instantly to sunlight can be found within and outside the eye in nearly every animal, and they govern not only vision but also a range of behaviors. Until about a quarter-century ago, though, the scientific consensus was that in humans, the only role for opsins was to help us see. But a surge of research over the past couple of decades has increasingly revealed that, like honeybees, zebrafish, rodents and other creatures, we harbor opsins that aren’t involved in vision, both in our eyes and throughout our bodies.”
