I think this is a Great Tailed Grackle, please comment if you think I am wrong. This is taken in my backyard in Arlington, Virginia.

This shows a cool engineering innovation: canvas-like material that when it is saturated with water will set (over 5+ hours) into hard concrete. In this example a “tent” with regular doors is covered with water and inflated. After setting it hard enough to climb on top of.
The manufacturer’s site has move information.

An Eukaryote that Completely Lacks Mitochondria

If you don’t have any idea what the title means that is ok. I probably wouldn’t have until the last 15 years when I found how interesting biology is thanks to the internet and wonderful resources online making biology interesting. I hope you find learning about biology as interesting as I do.
What they learned is that instead of relying on mitochondria to assemble iron-sulfur clusters, these cells use a different kind of machinery. And it looks like they acquired it from bacteria.
The researchers say this is the first example of any eukaryote that completely lacks mitochondria.
However, the results do not negate the idea that the acquisition of a mitochondrion was an important and perhaps defining event in the evolution of eukaryotic cells, he adds.
That’s because it seems clear that this organism’s ancestors had mitochondria that were then lost after the cells acquired their non-mitochondrial system for making iron-sulfur clusters.
Biology is amazing and mitochondria are one of the many amazing details. I wish so much that my education could have given biology a tiny fraction of the interest I have found it in after school.

Mountain Lion Roams from South Dakota all the way to 30 Miles from Manhattan

Over time he showed up in the Twin Cities of Minnesota and in Wisconsin. He disappeared for a couple months, then shows up almost two years later, 30 miles from Manhattan, in Greenwich, Connecticut. In all he probably traveled 2,000 to 5,000 miles, enough to cross the country twice. He forded all the major rivers of the East, navigated highways and an international boundary. It was one of the most spectacular journeys by an animal ever recorded.
