A Remarkable Time Lapse Video of Cell Division in a Frog Egg 

No, this isn’t digital. Filmed by documentary filmmaker Francis Chee, this amazing video captures the microscopic view of a frog egg as it begins to divide from two cells into millions over a period of about 33 hours. It’s astounding to think that each and every one of us started off just like this. (via Sploid)

A Captivating Film About People Working Through the Fear of Jumping from a Ten Meter High Dive 

In this documentary short titled Ten Meter Tower, Swedish filmmakers Maximilien Van Aertryck and Axel Danielson paid 67 people $30 to climb to the top of a ten meter (33 foot) high dive for the very first time all while being filmed. Would they decide to jump? Would they be too scared? The resulting footage is surprisingly riveting as people slowly come to terms with their fears and make a decision. It’s one thing to admit defeat in private, but adding the cameras must add a near insurmountable amount of pressure. The filmmakers share with the New York Times:

In our films, which we often call studies, we want to portray human behavior, rather than tell our own stories about it. We hope the result is a series of meaningful references, in the form of moving images. “Ten Meter Tower” may take place in Sweden, but we think it elucidates something essentially human, that transcends culture and origins. Overcoming our most cautious impulses with bravery unites all humankind. It’s something that has shaped us through the ages.

Ten Meter Tower premiered at the 2017 Sundance Film Festival. (via Metafilter)

An Amazing Split View of the Milky Way as If Photographed from Beneath a Frigid German River 

Johannes Holzer / Caters News Agency

Last October, photographer Johannes Holzer braved the winter cold to setup a series of long-exposure shots along the the Isar, a river in Southern Germany. To accomplish the eye-popping view of the Milky Way, a mountainous landscape, and the murky depths of the river he relied on two cameras to shoot three photos from roughly the same perspective, stitched together here in a final image. Holzer says the photo “was done with two cameras, [the] sky with a Sony A7r and Vixen Polarie Startracker, one additional shot for the landscape without [a] Startracker, [and] underwater was done with a Canon 5Dm2 with an EWA Underwater case.”

Holzer specializes in Milky Way photography and landscapes, you can see much more of his work on Karwendelbilder. (via Reddit)

Blooms 2: Extraordinary New Strobe-Animated Sculptures by John Edmark 

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.

The First Dinosaur Tail Found Preserved in Amber is Covered in Feathers

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.

Precisely Stacked Coin Towers That Defy Gravity 

tanu_07

Using common household props, Twitter user @thumb_tani stacks gravity-defying towers that rely on precise and calculated balance. Coins, toothpicks, and silverware are positioned to play off of each others’ weight in ways that might crumble with the slightest of touch. The sculptures go beyond experiments many might have seen before, ranging in shape from thick twirling cylinders to horizontal pieces that balance coins at the very edge of a knife’s blade. You can see more of his feats of balance, and incredible patience, posted to his Twitter. (via My Modern Met)
