Ever seen a cat that looks like a supermodel in a fur coat? Meet the Himalayan cat, the glamor queen (or king) of the feline world. With their long, luxurious coats and those striking blue eyes, they’re practically runway ready.

K.W. Lee was a pioneer in the journalism world. Known as the “Godfather of Asian-American Journalism”, Lee was the first Korean immigrant journalist for a mainstream newspaper in the continental U.S. The legacy he leaves behind was covered by the Sacramento Bee upon his passing this March.

Believed to be the first Korean immigrant to work for a mainstream U.S. newspaper, Lee carved out an extraordinary career as an investigative reporter, editor, publisher and mentor. His impact was national, but his work often centered on communities overlooked by traditional media.

With the successful launch of the TLV320DAC3100, we can do two things: keep jamming on Fruit Jam, and whip up a new breakout for its sister chip, the TLV320AIC3100 .

This one features stereo microphone inputs instead of two mix-in analog inputs and a DOUT pin. Technically, it has three mic inputs—one is differential/route-able, and we’re connecting that to the headphone jack since most headsets have an electret mic these days.

This chip is a really nice all-in-one I²S codec: perfect when you want stereo inputs, stereo headphone out, and mono speaker out. Honestly, we’re exploring whether it could be a viable replacement for the now-super-discontinued WM8960, especially since it can be configured not to require an external MCLK.

Do you remember the first time you understood the nature of a Venus flytrap? The very first time you heard that there lives, on this planet, a plant that with teeth and a mouth that eats animals. When you’re a kid, plants are tall and magestic like redwood trees or yucchy like broccoli or benign like the grass you’re suppored to mow. Plants are not, in any way, supposed to have a mouth and teeth and be able to eat living creatures. When you’re a kid, the first time you see a Venus flytrap slowly close its glistening jaws on a squirming ant seems might have felt like an encounter with an alien creature. As it turns out, the botanical worls is rich soil for speculative fiction. Here’s a review of Plants in Science Fiction by Octavia Cade at Strange Horizons:

Let’s start with creepy plants (“Botanical Tentacles in the Chthulucene” by Shelley Saguaro), because creepy plants are awesome and because there’s never any getting away from bloody Lovecraft, it seems, so let’s get shot of him first. Saguaro points out that “Tentacles are most often attributes of animal species, from giant squids and octopuses to microscopic flagellates and ciliates” (p. 56). Transplanting this animal imagery onto plants, then, gives a monstrous hybrid of a creature, one neither fully plant or animal, a creature defined by its boundary-crossing nature. Looking closely at plant tentacles in the works of H. P. Lovecraft, John Wyndham, and John Boyd, Saguaro comments that these “(frightened) men” (p. 73) were looking to navigate a world that increasingly did not centre them. While plant tentacles can represent the threat of a hybrid other, however—and it’s no coincidence that these creatures are often sourced from regions that white men such as the authors were trying to colonise—they can also be interpreted as a “liberating multi-species” flowering that encourages more diverse relationships and ways of living.

Back in December, engineers at Northwestern University successfully demonstrated quantum teleportation over a fiber optic cable already carrying Internet traffic. Check out the study published in Optica.

Only limited by the speed of light, quantum teleportation enables a new, ultra-fast, secure way to share information between distant network users, wherein direct transmission is not necessary. The process works by harnessing quantum entanglement, a technique in which two particles are linked, regardless of the distance between them. Instead of particles physically traveling to deliver information, entangled particles exchange information over great distances — without physically carrying it.

Maybe you never saw the 1982 movie TRON. Maybe you’d only ever seen the remake or maybe not even that because you heard that except for the Daft Punk sound track it wasn’t that good. But maybe you’ve stood inside the legendary TRON arcade game The Discs of TRON, the black light transforming you into a digital creature. Maybe you loved the sound of identity discs banking off glowing blue walls and maybe you felt your stomach fall as your avatar tumbled from the last reamining circular platform, derezzing into the microprocessor void, another victim fo the Master Control Program. Maybe when you finally saw the 1982 masterpiece its unique blend of computer generated images, blacklight animation, genre-defining production design, and live-action convincing abdolutely blew your mind. And maybe you knew in your meatworld bones that if you could ever venture inside TRON you’d absolutely rule at those lightcycles. Here’s an exploration of how the unique 1982 marvel was made, from The Guardian:

Tron’s distinctive glowing circuitry was achieved through a technique called backlight animation, which involves making a negative of each frame and hand-painting the glowing areas. There were 75,000 frames to do; more than half a million pieces of artwork. Nobody knew how it would come together until the last minute, and reshoots were virtually impossible.

Tron’s CGI elements were an entirely separate process. Computer graphics had been used in movies before Tron, but only in brief snippets. In 1973’s Westworld there is a clip of a robot’s-eye pixellated view, for example. Star Wars and Alien both feature 3D wireframe graphics projected on screens. Only a few companies could produce such images, each of which had their own room-sized computer and their own custom-built software. The process was still cumbersome. “We had to figure out how to position and render objects 24 times to make one second of perceived movement on the screen,” says Bill Kroyer, Tron’s head of computer animation. Tron’s animators had to map out the CGI scenes on graph paper, then calculate the coordinates and angles for each element in each frame. Computer engineers would then input all the numbers manually. And there was no way of seeing the results until the images were printed on to 35mm film and projected in the theatre.

NASA shares how astronomers used the Chandra X-ray Observatory and radio telescopes to explain a fracture in a huge cosmic “bone” in the Milky Way galaxy.

The bone appears to have been struck by a fast-moving, rapidly spinning neutron star, or pulsar. Neutron stars are the densest known stars and form from the collapse and explosion of massive stars. They often receive a powerful kick from these explosions, sending them away from the explosion’s location at high speeds.

The public domain is filled with celestial treasures, even in the most unexpected ways. boing boing shares how we always looked up.

“Flowers of the Sky” is a stunning collection of celestial art throughout the ages from the Public Domain Review. The artwork in this collection covers nearly a millennium of illustrations (chronologically) depicting comets, meteors, meteorites, and shooting stars. The earliest work in the collection is a shooting star, drawn in what looks to be pen and ink, from 1493. The latest is a surrealistic painting of space with a skull and large heads floating in the sky from 1910.

With a name that sounds like it belongs in a storybook, the tasselled wobbegong shark is one of the ocean’s most fascinating ambush predators.

If you've ever found a tick clinging to your skin after a hike or a romp in tall grass, you're not alone. These tiny critters are more than just a nuisance — they're also potential carriers of some serious diseases.

In the world of deep-sea exploration and innovation, OceanGate once stood at the crossroads of cutting-edge engineering and daring adventure.

Tortoiseshell cats, often called "torties," are the rebels of the feline world. With their swirls of orange and black, they’ve inspired myths, memes, and plenty of admiration from cat lovers. But there's more to a tortoiseshell cat than just striking looks.

Whether you're a fan of thrilling adventures or just like your horror movies with extra teeth, shark movies have carved out a unique spot in pop culture.

A versatile modular holder designed for dusters or other cylindrical objects that fit within its rings. The system is fully expandable, allowing you to add as many rings as needed. For a standard duster, a setup with two rings and one end piece typically works well.

A nice way to stack away your dusters into a cabinet, or similar.
