Olympic National Park’s rugged shoreline is rich with life. Invertebrates of countless shapes, sizes, colors and textures inhabit the tide pools along Washington’s coast. Pictured here is a starfish with Giant Green Anemones that opens its tentacles like flower petals in the tidal waters. Photo courtesy of Keith Ladzinski.

Tip for all my student readers: if you’re too lazy to use a bibliography creator like NoodleBib or RefWorks, let Google generate your bibliography entries for you. All you have to do is google the article/book title in Google Scholar, click “cite” at the bottom of the search result, and copy either the MLA, APA, or Chicago cite into your word document. 

I use http://owl.english.purdue.edu/owl/ to figure out how to cite for my papers, and it’s been quite useful for the three years I’ve been at this!

Amazingly cool Keokuk geode! Some of the Keokuk geodes contain oil (bitumen), they are found in an area near Niota in Hancock County, Illinois.  Research indicates that nearby oil deposits from Pennsylvanian-age rocks may somehow be linked to these interesting geodes.   Oil is able to migrate quite readily through certain soils and rock, and the conditions at the oil geode location may indicate a favourable environment for oil to reach the surface as the host rock that contains the geodes at this location is also frequently covered with a slick of oil.   NOTE OF CAUTION TO COLLECTORS:  These geodes, while interesting, are very messy to not only mine but also to have or store in a collection.  Make sure to store any collected geodes in a location that is free of dust and also that has a bottom that will not leak and can get dirty.  The oil has a way of soaking through anything permeable over time.

Don’t use these scare tactics - Chemicals aren’t inherently bad. Literally everything is made up chemicals. Trust me, your body knows what niacin is. It knows how to digest fructose and calcium sulfate. Even if you only consume the most basic and “real” foods that are pulled directly off the vine, you’re still ingesting a series of chemical compounds that you probably can’t pronounce. That’s okay. 

thanks to drhoz for submitting!

I’m pretty sure you can pronounce “arsenic”, but that doesn’t change the fact that arsenic is highly toxic. On the other hand, you couldn’t pronounce “cycloadenosine monophosphate” or “nicotine-amide-dinucleotide-phosphate”, though both of them serve vital roles in human biochemistry and you would die if your body wouldn’t produce them.

It’s more important to know what the chemicals are and why they’re in there.  Anti-intellectualism helps no one.

Males put their bright colors and unusual ornaments to good use when they display for females. Their elaborate dances, poses, and other rituals accentuate their appearance and put on a phenomenal show for both female birds and any humans lucky enough to be in the vicinity. Such displays can last for hours, and in many species they consume a significant part of the male’s time.
