This is the second metallic green insect that I have found in my backyard over the last few days. Chalybion californicum is the scientific name of the Blue Mud Dauber. I was lucky to snap a shot of it because they are lightning fast! They range in darkness and in color from blue to green.
Not only do Blue Mud Daubers prey upon Black Widow spiders, but this beauty was kind enough to pause briefly for a photo. Come back any time little buddy!

The Biology section of The Science Outpost has not yet been developed. Here is a temporary Biology page.
Here are images (DON’T READ THE CAPTIONS YET!) of three important biological macromolecules.
One of them is a nucleic acid.
One of them is a protein (the most abundant protein on Earth!).
One of them is a little bit of both, a ribonucleoprotein.
Can you guess which one is which before you read the captions?
What good is DNA without a ribosome? Considering how the ribosome has changed over the last 4 billion years gives insight to the crucial nature of its role in biology, the unity of all life, and the process of evolution.
In the new study, Williams and Research Scientist Anton Petrov compared three-dimensional structures of ribosomes from a variety of species of varying biological complexity, including humans, yeast, bacteria and archaea. The researchers found distinct fingerprints in the ribosomes where new structures were added to the ribosomal surface without altering the pre-existing ribosomal core from the last universal common ancestor.
