Science Friday

Reporting in the journal Nature Physics, William Irvine and Dustin Kleckner, physicists at the University of Chicago, describe the knotted fluid vortex they created in the lab -- a scientific first, they say. The knots resemble smoke rings -- except these are made of water, and they're shaped like pretzels, not donuts. Understanding knottiness has extra-large applications, including untangling dynamics of the sun.

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).* Each bloom’s particular form and behavior is determined by a unique parametric seed I call a phi-nome (/fī nōm/). -John Edmark

What do plants know about numbers? A certain spiral pattern commonly seen in sunflowers, pinecones, and many species of cacti contains some surprising numerical properties. In this brisk talk, Paul Dancstep investigates this pattern through several kinetic sculptures by artist John Edmark. These mesmerizing artworks provide a number of insights into the mathematical lives of plants.

overtone singing is a voice technique where it seems like one person sings two notes at the same time. You can sing the overtone scale on one fundamental. Another fundamental has its own overtone scale, so in order to have more overtones to sing nice melodies, you can use different fundamentals and change them while singing.

this video is live, and every human being is capable of learning overtone singing ;)

For USGS wildlife biologist Karyn Rode, tracking and tranquilizing polar bears from a helicopter are just the first thrilling steps in her research. After acquiring various samples from sleeping bears, Dr. Rode's unique understanding of what they eat and how quickly they metabolize nutrients allows her to determine the condition of each bear. Working with a team of scientists from the US Fish and Wildlife Service for nearly a decade, Dr. Rode's monitoring of polar bear health has helped reveal how well populations are adapting to the rapidly warming Arctic.

Biomechanists use many high-tech tools such as MRI or CT scanning to visualize the connective tissues of specimens. But for Dr. Adam Summers of the University of Washington's Friday Harbor Labs - none of these methods provide the inspiration of clearing and staining. Using a cocktail of chemicals, clearing and staining turns soft tissues transparent while tinting bones and cartilage bright red and blue. Preparing gobies, stingrays, and sharks in this manner has revealed to Dr. Adam Summers critical data while allowing him, and us, to appreciate the beauty of each fish's form.

Cuttlefish change the patterns on their body for courtship rituals, when they eat a snack, and most famously when they want to blend in. How they change their skin patterns may tell us something about how they see the world, says Duke biologist Sarah Zylinski. Her work suggests that when cuttlefish see incomplete shapes, they fill in the visual blanks -- much like humans do. Can't get enough saltwater camouflage? Watch: Where's The Octopus?

For centuries, maple syrup producers across New England and Canada harvested sap by drilling into the bark of fully grown wild trees. While commercial syrup producers have adopted vacuum pumps and plastic tubing to aid these efforts, recent experiments at the University of Vermont's Proctor Maple Research Center may further pull the industry from its pastoral roots. By vacuum-sucking sap directly from the cut tops of juvenile trees, the researchers increased syrup production 5 to 6 times per acre compared to the traditional sap collecting methods.

Crawling, swimming, squeezing, jetting—the range of movement available to an octopus is impressive. Yet some species occasionally choose to stand up on two arms and run backwards. Chrissy Huffard, a Senior Researcher at the Monterey Bay Aquarium Research Institute, explains the pros and cons of this seemingly silly behavior and why an octopus might find looking foolish useful.

Did you know that most mammals, from a house cat to an elephant, take roughly the same amount of time to urinate? Researchers at Georgia Tech collected data, streamed via online video and in real life, and discovered that a combination of physiology and gravity enable this feat of fluid dynamics.

With its fanned plumage and bold strut, a male wild turkey's display conjures images of Americana and festive feasts. But this grandstanding isn't intended for human eyes - it's for female turkeys who actually use it to discern a male's genetic prowess. How exactly she parses his performance to pick her suitor can be a fairly complex enterprise but thanks to the research of Dr. Richard Buchholz of the University of Mississippi, we have some clues as to what a female turkey finds hot in a male.

As a choreographer who often collaborates with dancers with disabilities, Merry Lynn Morris has long thought that traditional manual and power wheelchair designs were constraining. Her work in integrative dance, along with her experience growing up with a father who relied on a wheelchair, inspired her to invent a power wheelchair designed for artistic expression. Equipped with omnidirectional movement, a rotating seat, and a hands-free control, the chair enables dancers to explore new movement techniques, and may one day provide greater mobility in everyday life, too.

With their ornately-colored bodies, rhythmic pulsations, and booty-shaking dance moves, male peacock spiders attract the attention of spectating females as well as researchers. One such animal behavior specialist, Madeline Girard, collected more than 30 different peacock spider species from the wilds of Australia and brought them back to her lab at UC Berkeley. Under controlled conditions, she recorded their unique dances in the hopes of deciphering what these displays actual say to a female spider and how standards differ between species.

SCIENCE FRIDAY'S CEPHALOPOD WEEK 2016 BEGINS May 17th!

With thousands of chemically-sensitive suckers, color-changing skin, and a brain that literally stretches when they eat, octopuses seem like aliens living in our oceans. Understanding their physical adaptations and how octopuses might process their own sensations requires a flexible imagination. Thankfully, Frank Grasso of Brooklyn College is up to the task. He reveals some of the small biological and behavioral clues that researchers have uncovered as they try to understand these curious creatures.

Electric eels zap fish and other underwater prey, but what would make them leap out of the water and shock an animal like a horse? Nineteenth-century naturalist and explorer Alexander von Humboldt first described eels emerging from the water to attack horses, and now Kenneth Catania of Vanderbilt University uses some unique props to reveal shocking insights about the behavior.

Behold The Future...Creating The Never-Ending Bloom: John Edmark’s spiral geometries. Artist, designer, inventor, and Stanford professor John Edmark creates sculptures that are driven by precise mathematics, but his interest in spiral geometries is driven by something more enigmatic… “a search for unusual behaviors, things that are non-intuitive, that maybe seem impossible.”

In this SciFri Arts video, Edmark shares the evolution of his exploration, from spiraling Fibonacci puzzles, to Golden Angle towers, to 3D-printed, zoetrope-like shapes that seem to grow endlessly when animated under a strobe light: Creating The Never-Ending Bloom.



---------------------------------------------------------------------------------------------

John Edmark Website Statement

If change is the only constant in nature, it is written in the language of geometry.

Much of my work celebrates the patterns underlying space and growth. Through kinetic sculptures and transformable objects, I strive to give viewers access to the surprising structures hidden within apparently amorphous space.

While art is often a vehicle for fantasy, my work is an invitation to plunge deeper into our own world and discover just how astonishing it can be. In experiencing a surprising behavior, one’s sense of wonder and delight is increased by the recognition that it is occurring within the context of actual physical constraints. The works can be thought of as instruments that amplify our awareness of the sometimes tenuous relationship between facts and perception.

I employ precise mathematics in the design and fabrication of my work. I do this neither out of a desire to exhibit precision per se, nor to exalt the latest technology, but because the questions I’m trying to formulate and answer about spatial relationships can only be addressed with geometrically exacting constructions. Mathematical precision is an essential ally in my goal of achieving clarity.

Nature is generous and inexhaustible, rewarding curiosity with startling insights and an abundance of ever more beautiful mysteries. Through my work I endeavor to share the joy of discovery with others in a continuing pursuit of the timeless patterns of change.

Blooms are 3D 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). Each bloom’s particular form and behavior is determined by a unique parametric seed I call a phi-nome (/fī nōm/).

For this video, rather than using a strobe, the camera was set to a very short shutter speed in order to freeze individual frames of the spinning sculpture.

It could be at least 15 years before NASA lands a mission on Europa, one of Jupiter's moons, to search for signs of life beneath its icy crust. In the mean time, a team led by astrobiologist Kevin Hand of NASA's Jet Propulsion Laboratory is using ultra-chilled vacuum chambers to simulate what Europa's surface might be like. Their work will inform future missions and give scientists clues to how they might detect life on a faraway moon.

In 1977, NASA launched Voyager 1 and 2 to explore and document our solar system and the interstellar space beyond. The craft will drift for billions of years in the emptiness, each carrying a Golden Record inscribed with our message to any intelligent spacefaring civilization that discovers it.

Creating The Never Ending Bloom The Amazing Mathematical Wonders of John Edmark
We’ve long marveled at artist John Edmark's (previously) kinetic objects that function as a medium to express a variety of mathematical formulas and concepts. The spiral-like sculptures often defy description and even when looking at them it’s hard to understand how they work, something he refers to as “instruments that amplify our awareness of the sometimes tenuous relationship between facts and perception.” The folks at SciFri recently visited with Edmark in his studio to learn more about how he works and to catch a glimpse of some rather unusual sculptures he’s created over the last few years.
