Tuesday Ephemera: Chipmunk Revolution

Tonight’s music video is “Rescue, Mister” by TR/ST. This video was selected by Ósk Bät as part of Ósk’s “Daily Earworms” on the social network ello.

I’m on ello too, as @kitoconnell (just like on Twitter and Instagram). I’m finding the new social network a pleasant place to share photos and text without the issues of Facebook’s bothersome algorithm hiding my content.

Scientists believe that fossil remains of Megasphaera may represent one of the earliest animals to live on earth. From Live Science:

A new study finds that these controversial fossils are not likely to be bacteria or single-celled protists; their cells, preserved for more than 600 million years in rock, are too complex and differentiated. Instead, the fossils may be multicellular algae, or even the embryosof ancient animals. “The real value of these fossils is that we now have some direct evidence about how this transition from single-celled organisms to things like animals and plants occurred in the evolutionary past,” said study researcher Shuhai Xiao, a geobiologist at Virginia Tech in Blacksburg.

[…] The bizarre fossils, known as Megasphaera, come from a rock layer in southern China called the Doushantuo Formation. Xiao first studiedMegasphaera specimens in 1998 and suspected that they might beanimal embryos. Each fossil measures a mere 0.03 inches (0.7 millimeters) or so across and comes from what would have been a shallow marine environment at the time. But no adult animals that might have produced these embryos have ever been found, leaving the identity of the fossils open to scrutiny.

[…] By slicing the rocks ultrathin, the researchers were able to shine light through the fossils to see the structures inside, just like stained glass. Using microscopy, they observed multiple cells, cleaved together in spherical clusters. The cells were different from one another in shape and size, suggesting they have developed different tissue types — a process known as cell differentiation — and presumably have different cellular functions, Xiao said.

New On Mint Press News: I filed a report with MyMPN about a recent direct action by Utah Tar Sands Resistance activists dressed as chipmunks.

Activists dressed as chipmunks shut down construction at the first US tar sands mine on September 23. It was the latest in a series of actions by Utah Tar Sands Resistance targeting the 213 acre Book Cliffs tar sands mine.

A video released by the group shows chipmunks spreading rapidly through through the camp site where they block construction equipment with their bodies. Activists shut down construction for part of a day, resulting in five arrests. There have been 27 total arrests since the beginning of the campaign to halt construction.

“This project is a bellweather project,” said Raphael Cordray, an organizer with Utah Tar Sands Resistance. “If they can make this project successful than it will open up the flood gates for a whole lot of other tar sands and oil shale strip mining projects in the area and in America in general. The United States Bureau of Land Management identified 860,000 acres within Utah, Wyoming and Colorado that’s available in the future.”
