Avid photographer and retired environmental consultant Alison Pollack documents the fascinating phenotypes of mushrooms and slime molds she encounters on hikes in northern California. Her images show shaggy white Comb Tooth fungus (Hericium coralloides), Stemonitis slime molds that wouldn’t look out of place on the dessert menu of an experimental restaurant, and Comatricha that bear a strong resemblance to urban lamp posts. Recently, the north Bay Area-based photographer shared with the Marin Independent Journal that she has had a longtime interest in hiking and mushrooming, but has grown more focused on fungi photography in the last two years. You can follow along with Pollock’s findings, and help her identify unknown species, on Instagram.

Searing Bands of White Light Mark the Ocean’s Rising Tides in a Coastal Community

Documentation of Installation by Pekka Niittyvirta & Timo Aho

A chilling new installation in the Outer Hebrides shows the impact of climate change and rising tides on the low-lying islands off the west coast of Scotland. Lines (57° 59 ́N, 7° 16 ́W)  was created by Finnish artists Pekka Niittyvirta and Timo Aho for Taigh Chearsabhagh Museum & Arts Centre in Lochmaddy on the island of North Uist. The site-specific installation uses sensors and LED lights to show where the water will flow during storm surges if the Earth’s temperature continues to rise. Searing white lines mark this rising water level on the sides of buildings, hover over bridges, and extend across other susceptible areas across the museum campus and surrounding community.

The installation’s delineations starkly demonstrate the ticking clock that makes the museum’s current location unsustainable unless drastic measures are taken to stop climate change. The video below shows the artists’ installation process. You can see more from Niittyvirta and Aho on their websites. (via designboom)

Upcycled Lobster Shells are Transformed into Functional Planters and Packages

February 22, 2019

Laura Staugaitis

Four designers from the Royal College of Art and Imperial College have found a second life for the lobster tail you might’ve splurged on for Valentine’s Day. The project team, dubbed Shellworks, created a bioplastic by combining vinegar with chitin, a fibrous substance that is the main component of crustacean’s shells, as well as fungi cell walls. Though there is currently a commercially available version of chitin, called chitosan, it is extremely expensive.

The Shellworks team created five of their own machines, named Shelly, Sheety, Vaccy, Dippy and Drippy, to manipulate the chitin-based materials with varying stiffness, flexibility, thickness, and translucence. The resulting range of potential products includes self-fertilizing planters, pill blister packs, and food containers, which can be recycled or composted. By making this process more accessible and affordable, Shellworks hopes that their innovations might allow for larger-scale replacement of the plastic we use every day. You can learn more about the project in the video below, and on the Shellworks website and Instagram. (via dezeen)

Extreme Temperatures Breed Glassy Hollow Forms Called ‘Ghost Apples’

February 15, 2019

You’ve seen the perfect arcs of boiling water solidified mid-throw, and perhaps this frozen speeding sign that duplicated itself over 2019’s Polar Vortex, but have you seen ghost apples? Thanks to a Facebook post by farm manager Andrew Sietsma, the phenomenon has captivated the internet, leaving commenters to marvel at the sight of these glass-like specimens that remain after apples have rotted from their icy exterior. Sietsema told CNN that this winter the weather in western Michigan was “just cold enough that the ice covering the apple hadn’t melted yet, but it was warm enough that the apple inside turned to complete mush (apples have a lower freezing point than water).” Jonagolds are one of Sietsema’s favorite apple varieties, but on the farm they are now referred to as “Jonaghosts.” (via Reddit and Bored Panda)

An Extraordinary Time-Lapse Captures the Microscopic Development of a Single Cell into a Newt

February 7, 2019

Kate Sierzputowski

In Becoming, a time-lapse film by Jan van IJken (previously), a single cell splits. Then it splits again, and again, and again, morphing and quivering as new quadrants continually appear and divide. The cell belongs to an alpine newt, and during most of its transition from a single cell zygote to hatched larva it looks remarkably like a sunny-side up egg. The film’s rapid timeline condenses four weeks of growth into six minutes, presenting a speedy and awe-inspiring glimpse at how we all begin.

“I wanted to capture the origin of life,” van IJken tells Colossal. “What is particularly interesting I think, is that the basics of embryonic development are the same for all animals, including us. I think the way we develop is a true miracle. In my film you can see individual cells move to the place where they belong in the embryo. How is this possible? It is all managed by a precise internal clockwork in each individual cell.”

Van IJken used time-lapse photography and video in combination with a trinocular microscope to precisely observe the details of the newt’s development. You can view more of his work, including a trailer for his first film Facing Animals, on Vimeo.

GPS Map Composed of 68,000 Pinpoints Tracks the Territorial Nature of Minnesota Wolves

January 31, 2019

The Voyageurs Wolf Project is a collaboration between the University of Minnesota and Voyageurs National Park which tracks and studies wolves throughout the warmer months. In 2018, the project studied six northern Minnesota packs, creating a map that showcases the intensely territorial way the animals behave, and how tightly they stick to their packs. The brightly colored line drawings were composed from 68,000 GPS locations of the six packs, with negligible crossover between the data-driven formations.

Not only does the information help researchers track where wolves have been, but also which prey the wolves have killed. “This detailed GPS-data is incredibly valuable for understanding pack boundaries and also for our predation research,” explains a post from the Voyageurs Wolf Project. “We visited every spot these wolves spent more than 20 minutes to determine if the wolves made a kill. This required an estimated 5,000 miles of hiking this past summer from our field crew!!”

After the original map circulated widely, the team decided to bring the information to life, which you can observe in the GIF below. The moving image includes data from April 15, 2018 to the end of October of the same year, with GPS locations taken every 20 minutes. You can follow more data collected by the Minnesota-based team on Facebook. (via Twisted Sifter)

A Gigantic Circular Ice Patch Formed in a River in Westbrook, Maine

January 16, 2019

Earlier this week a peculiar phenomenon was discovered in a section of the Presumpscot River in Westbrook, Maine. In the chilly winter waters a gigantic disk of ice had formed with a diameter just short of the river’s width. The floating patch was recently captured by the city in an aerial video. In the footage a nearby parking garage seems dwarfed by the mammoth proportions of the circular ice patch. According to Westbrook’s marketing and communications manager Tine Radel, the icy island has been spinning in a counterclockwise direction, and does not appear to be moving up or downstream. You can view an aerial tour of the floating ice patch (set to a pretty dramatic soundtrack) in the video produced by the City of Westbrook below. (via Earther)
