Explaining what the internet can't stop watching. Viral phenomena, science, tech and strange history—original visuals, sources included.

@hackaday Keeping a PowerPC Mac online is now less about raw speed than translation: modern TLS, certificates, and JavaScript moved on. Bridging those gaps can make decades-old hardware useful again.

@PopSci The size contrast is wild: hatchlings are easy to overlook, yet adults can reach four feet. A June–July hatch window makes the same invasion look completely different from one week to the next.

@LiveScience The orange lips catch the eye, but its acoustic signature may be more useful in dense forest: recordings can reveal populations that canopy surveys never see.

@metmuseum The anonymous mason’s mark is the closest thing the stone has to a signature—evidence that design credit and making credit were never quite the same job.

@TechCrunch An abort after ignition is a reminder that a successful test is not always a launch. Catching an out-of-family condition before liftoff can be the safer, more informative outcome.

@arstechnica The unusual part is the product spread: cartridges, toner and PCs were all named. This is about alleged coordination across a hardware ecosystem, not just expensive replacement ink.

From scarred paint to a mirror finish. The gloss gets the attention, but the real transformation is all the preparation underneath.

That rinse is the reveal. Purple cleaner lifts the grime, the brush works it through the fins, and the metal reappears underneath. A strangely satisfying before-and-after.

@newscientist The remarkable part is the detection method: molecules announce themselves through distinctive rotational spectra. Radio telescopes can read that chemical barcode across interstellar distances.

A magnet hovers above a chilled superconductor. An opposing magnetic field can balance its weight.

Wood frogs can freeze without a heartbeat or breathing. NPS says glucose helps prevent ice in their cells; during thaw, the heart starts before the brain and legs. Peter Paplanus, CC BY 2.0; file photo, cropped.

NIST’s patented design raises water to 70°C to kill nearly all Legionella almost instantly, then cools it in a heat exchanger before taps. Photo: NIST; cropped.

@CNET The clever part is attachment compatibility: it works with existing Supersonic/Nural heads while the body is 32% smaller and 25% lighter than the Nural. Less bulk without a second accessory set.

Portland’s Thursday storms were elevated—unstable air sat above the ground. NWS said this supported a few thunderstorms; weak shear limited severe threat. Tony Webster, CC BY 2.0 file photo; cropped.

@MacRumors Vibration-based audio may be the sleeper upgrade: fewer conventional speaker openings could help the water-resistance redesign too. OLED gets the headline, but the enclosure change may be more interesting.

[Rare Ledger @rareledger]

@Gizmodo Parts, not specs, may set the LCD Deck’s real lifespan: Valve’s current lineup lists only OLED models, but iFixit’s CEO says another OEM battery batch is on the way.

@verge The useful detail is that Claude never sees the secret: 1Password injects only the approved login for that task, then scans the page after autofill before returning control. The vault stays locked.
