The folks over at London-based Little Planet Factory make tiny 3d-printed planets and moons you can sit on your desktop or hold in your hands. Designs include everything from entire solar systems to collections of moons, individual planets, and even science fiction creations like a theoretical terraformed Mars globe. See more in their shop!

This weekend, word spread via Facebook that a large circle of ice was spinning in small river just outside of Seattle. After seeing a quick video of it in her feed, photographer Kaylyn Messer jumped in her car and was fortunate to witness the incredible sight of this gargantuan ice disc as it spun in the current of the Middle Fork Snoqualmie River.
“The ice circle was pretty captivating,” Messer shared with Colossal. “You can hear the sound of the river flowing continuously. Sounds from the ice periodically interjected with very small sharp cracks and groans. Overall, it was a quiet experience to stand along the river watching the ice circle rotate.”
Ice circles are a fairly rare phenomenon that occur mostly in North America and Scandinavia in slow moving rivers during the winter. The discs are formed when a large piece of ice breaks off in the river creating an effect called ‘rotational shear’ where the current slowly grinds away at the free-floating chunk until its smoothed into a perfect circle.
Messer shares more photos and videos of the ice disc on her blog.
As artist John Edmark's sculptures wiggle, wobble, and twist before your eyes like some alien creature, it’s hard to believe that what you’re seeing is a real physical object—but we assure you it is, with a bit of trick photography and some heady mathematics thrown in for good measure. Blooms 2 (a year in the making) is the latest collection of wild strobe-animated sculptures that begin life as computer programs written in Python before being 3D printed and set in motion on a table, but the patterns you see are created, in a sense, by nature itself.
“Blooms are based on the same geometry nature uses in many plant forms, including artichokes, sunflowers, and pinecones, all of which share the same underlying mathematical pattern,” Edmark shares with Colossal. He explains in more detail how each sculpture is designed:
Blooms are 3-D printed sculptures designed to animate when spun under a strobe light. Unlike a 3D zoetrope, which animates a sequence of small changes to objects, a bloom animates as a single self-contained sculpture. The bloom’s animation effect is achieved by progressive rotations of the golden ratio, phi (ϕ), the same ratio that nature employs to generate the spiral patterns we see in pinecones and sunflowers. The rotational speed and strobe rate of the bloom are synchronized so that one flash occurs every time the bloom turns 137.5º (the angular version of phi).
While the strobe is necessary to witness the animation when viewing these pieces in person, for the sake of creating this video filmmaker Charlie Nordstrom set the camera to a short shutter speed that freezes individual “frames” of the spinning sculpture.
Many of Edmark’s pieces are now in galleries and permanent museum collections around the world. You can see several of his sculptures right now at the Exploratorium in San Francisco and the Technorama in Winterthur, Switzerland. You can also see some of his first designs in his original Blooms video, and for what it’s worth, we also carry his amazing Helicone sculpture in the Colossal Shop.
Starting with a recording of raindrops hitting the skylight in his old apartment, this track titled Order from Chaos from London-based artist Max Cooper‘s newest album Emergence is the culmination of three years work merging his interests in science, music and visual arts. French visual effects artist Maxime Causeret was asked to provide the visuals and the result is a mesmerizing blend of biological simulations and music video. Cellular forms appear to collide, merge, and even compete for resources while brain-like structures explode and crash across the screen. Cooper explains a bit of the science behind the art:
Maxime Causeret selected this track to work with, under the brief to map the emergent rhythm to an exploration of emergence in living form. His video shows the raindrops initially, then going into simple cellular forms and then showing the important idea of cooperation between simple cells to form more robust colonies of life. This develops into a visualisation of the idea of endosymbiosis, where simpler smaller organisms can live inside larger cells, each providing a benefit to the other, and eventually forming parts of the same organism as they evolve to be entirely dependent on each other.
Fullscreen, headphones, you know the drill. This is definitely worth getting lost in for a moment. You can listen to Cooper’s full album here.

The first known dinosaur tail preserved in a piece of amber was recently discovered by paleontologist Lida Xing while collection samples in Myanmar last year. Dating back to the mid-Cretaceous Period some 99 million years ago, the roughly apricot-sized piece of amber contains a 1.4-inch appendage of 8 vertebrae unmistakably covered in primitive feathers. Scientists ruled out the possibility of the tail belonging to a bird, and based on its structure believe it came from a juvenile coelurosaur, a group of dinosaurs that includes tyrannosaurs. Via National Geographic:
While individual dinosaur-era feathers have been found in amber, and evidence for feathered dinosaurs is captured in fossil impressions, this is the first time that scientists are able to clearly associate well-preserved feathers with a dinosaur, and in turn gain a better understanding of the evolution and structure of dinosaur feathers.
The findings were first published today in a report co-authored by Ryan McKellar in Current Biology and you can read more on National Geographic.
