Stranger Visions: DNA Collected from Found Objects Used to Create 3D Portraits

Stranger Visions: DNA Collected from Found Objects Used to Create 3D Portraits science portraits genetics DNA 3d printing

You’re walking down a street in Brooklyn, gnawing on a piece of gum that’s past the point of flavorful.. In a hurry, you spit it on the ground without a second thought and continue about your day. Hours later, a mysterious woman arrives, surreptitiously collecting the sticky gum from the sidewalk and dropping it into a clear plastic bag which she then carefully labels. Flash forward a month later: you’re walking through an art gallery, and there, mounted on the wall, is a familiar face staring back at you. Astonishingly (or terrifyingly), it’s a 3D print of your face generated from the DNA you left behind on that random piece of gum that now appears in a petri dish just below the portrait. A few years ago this would have seemed like science fiction, the stuff of films like Gattaca, but to information artist Heather Dewey-Hagborg, it’s how she makes her artwork here in 2013.

They say inspiration can strike anywhere. For Dewey-Hagborg, it happened in a therapy session. While staring at a framed print on the wall, she fixated on a tiny crack in the glass into which a small hair had become lodged. As her mind wandered, she imagined who this seemingly insignificant hair belonged to, and, more specifically, what they might look like. After that day, she became keenly aware of the genetic trail left by every person in their daily life, and began to question what physical characteristics could be identified through the DNA left behind on a piece of gum or cigarette butt.

Stranger Visions is the result of her fascinating, if slightly disconcerting, line of questioning and experimentation: 3D printed portraits based on DNA samples taken from objects found on the streets of Brooklyn. Dewey-Hagborg worked with a DIY biology lab called Genspace, where she met a number of biologists who taught her everything she now knows about molecular biology and DNA. Via an interview with the artist:

So I extract the DNA in the lab and then I amplify certain regions of it using a technique called PCR – Polymerase Chain Reaction. This allows me to study certain regions of the genome that tend to vary person to person, what are called SNPs or Single Nucleotide Polymorphisms.

I send the results of my PCR reactions off to a lab for sequencing and what I get back are basically text files filled with sequences of As, Ts, Cs, and Gs, the nucleotides that compose DNA. I align these using a bioinformatics program and determine what allele is present for a particular SNP on each sample.

Then I feed this information into a custom computer program I wrote which takes all these values which code for physical genetic traits and parameterizes a 3d model of a face to represent them. For example gender, ancestry, eye color, hair color, freckles, lighter or darker skin, and certain facial features like nose width and distance between eyes are some of the features I am in the process of studying.

I add some finishing touches to the model in 3d software and then export it for printing on a 3d printer. I use a Zcorp printer which prints in full color using a powder type material, kind of like sand and glue.

The resulting portraits are bizarre approximations of anonymous people who unknowingly left their genetic material on a random city street. So how accurate are the faces created from this genetic experiment? The artist likes to say they have a “family resemblance” and no, unlike the scenario depicted above, a person has never recognized themselves in any of her exhibitions. Yet. There are some things such as age which are virtually impossible to determine from DNA alone, so Dewey-Hagborg casts each portrait as if the person were around 25 years old.

Magnetic putty is just like any other putty in that you can handle it, sculpt it, and squeeze it in a fist as you visualize your enemies. But place it anywhere near a strong magnetic field and it will SPONTANEOUSLY ANIMATE and move to consume anything magnetic in its path like a voracious mutated slug. In fact the putty won’t stop moving until the object has been equally engulfed on all sides. PBS Digital Studios and Shanks FX used the putty in parts of their recent film short SCI-FLY, and just posted this extended cut of special effects shots that explore its heinous capabilities. To be fair, these clips are sped up quite a bit as the actual motion of the putty consuming other objects is only faintly perceptible in real time. Want to experiment with magnetic putty yourself? Get it here.

So this is completely amazing. Destin from Smarter Every Day stopped by Orbix Hot Glass in Fort Payne, Alabama to explore a fascinating phenomenon called a Prince Rupert’s Drop. Apparently when molten hot glass is dropped in cold water it forms an object that’s almost completely impervious to brute force, even a sold hammer strike to the center of the teardrop-like shape won’t break the glass. Yet gently cut or even bump the tip of the drop and suddenly the entire thing shatters in an explosive chain reaction traveling at a speed of over 1 mile PER SECOND. Watch the video above to see the effect in 130,000 fps glory. (via the awesomer)

This is What Happens When You Run Water Through a 24hz Sine Wave

This is What Happens When You Run Water Through a 24hz Sine Wave water sound science

What!? How is this even possible? Because science, my friends. Brusspup’s (previously) latest video explores what happens when a stream of water is exposed to an audio speaker producing a loud 24hz sine wave. If I understand correctly the camera frame rate has been adjusted to the match the vibration of the air (so, 24fps) thus creating … magic zigzagging water. Or something. Here’s a little more detail:

Run the rubber hose down past the speaker so that the hose touches the speaker. Leave about 1 or 2 inches of the hose hanging past the bottom of the speaker. Secure the hose to the speaker with tape or whatever works best for you. The goal is to make sure the hose is touching the actual speaker so that when the speaker produces sound (vibrates) it will vibrate the hose.

Set up your camera and switch it to 24 fps. The higher the shutter speed the better the results. But also keep in the mind that the higher your shutter speed, the more light you need. Run an audio cable from your computer to the speaker. Set your tone generating software to 24hz and hit play. Turn on the water. Now look through the camera and watch the magic begin. If you want the water to look like it’s moving backward set the frequency to 23hz. If you want to look like it’s moving forward in slow motion set it to 25hz.

Brusspup did a similar experiment last year where it looked as if the water was flowing in reverse. Can somebody please make a water fountain that does this or would we all be deaf? (via stellar)

Every single day in 2013 San Francisco-based artist Klari Reis is creating an abstract painting inside the confines of the humble petri dish, a cylindrical container used by biologists to culture the growth of cells and algae, something the paintings seem to directly resemble. Called ‘Daily Dish 2013‘ the project is a continuation of a series Reis completed back in 2009, but at a cursory glance I’m already enjoying the 2013 series much more. Despite the limitation of medium and space, it’s amazing to see the variation of color and depth each painting has, for some reason it reminded me of Jason Fried’s 2007 SvN post about the variation of watch faces.

Alan Friedman is a fascinating guy. By day he’s a maker of greeting cards and a lover of hats, but in his spare time he’s a self-proclaimed space cowboy who points a telescope skyward from his backyard in downtown Buffalo, directly into the light of the sun. Using special filters attached to his camera Friedman captures some of the most lovely details of the Sun’s roiling surface. The raw images are colorless and often blurry requiring numerous hours of coloring, adjusting and finessing to tease out the finest details, the results of which hardly resemble what I imagine the 5,500 degree (Celsius) surface of Sun might look like. Instead Friedman’s photos appear almost calm and serene, perhaps an entire planet of fluffy clouds or cotton candy. From his artist statement:

My photographs comprise a solar diary, portraits of a moment in the life of our local star. Most are captured from my backyard in Buffalo, NY. Using a small telescope and narrow band filters I can capture details in high resolution and record movements in the solar atmosphere that change over hours and sometimes minutes. The raw material for my work is black and white and often blurry. As I prepare the pictures, color is applied and tonality is adjusted to better render the features. It is photojournalism of a sort. The portraits are real, not painted. Aesthetic decisions are made with respect for accuracy as well as for the power of the image.

Although the photos above are amazing, Friedman offers extremely high-resolution views of his work on his Tumblr and you can pick up some prints over on Photo-Eye. He also recently gave a TEDx Talk. (via geocentrismo)

These beautiful and other-worldly photographs of ice were taken last year by University of Washington graduate student Jeff Bowman and his professor Jody Deming while they worked on a study combining oceanography, microbiology, and planetary sciences in the central Arctic Ocean as part of the Integrated Graduate Education and Research Training (IGERT) program. Their single focus was the study of frost flowers, a strange phenomenon where frost grows from imperfections in the surface ice amid extreme sub-zero temperatures nearing -22C or -7.6F, forming spiky structures that have been found to house microorganisms. In fact, the bacteria found in the frost flowers is much more dense than in the frozen water below it, meaning each flower is essentially a temporary ecosystem, not unlike a coral reef. Via IGERT:

Around their research icebreaker in the central Arctic Ocean new ice grows on long open cracks that network amongst the thick floes of pack ice. Abruptly the surface of this new ice changes texture. The cold, moist air above the open cracks becomes saturated and frost begins to form wherever an imperfection can be found on the ice surface. From these nucleation points the flower-like frost structures grow vertically, quickly rising to centimeters in height. The hollow tendrils of these “frost flowers” begin to wick moisture from the ice surface, incorporating salt, marine bacteria, and other substances as they grow. The fog dissipates and the Arctic sun lights the surface of the frost flowers, initiating a cascade of chemical reactions. These reactions can produce formaldehyde, deplete ozone, and actually alter the chemical composition of the lower atmosphere. [...] Bowman and Deming have discovered that bacteria are consistently more abundant in frost flowers than in sea ice. Since microscopic pockets in sea ice are known to support an active community of psychrophiles (cold-loving microorganisms), even in the coldest months of the year, these results are encouraging.

Bowman and Deming are currently building an ultra-clean chamber where they can grow artificial frost flowers and hope that their research leads to a better understanding of how life might be able to survive in extreme conditions elsewhere in the universe. Amazing! Photos by Matthias Wietz. (via the daily what)
