Rules:
- Search for and then submit in the comment box below an article which relates to this lab's topic that has both an interesting and exciting story.
- Include with your submission: your name, your section, the title of the article and the URL link to it's source. Additionally, upon submitting the above, I ask that you also include a very brief description. Hint: make your article stand out, in other words, make me want to read what you've found.
- Should you be selected as one of the lucky three, you will be required to write a 200 to 500 word blog post that describes the article you found. The post you write up will be featured on this blog. Your post must include citations and references giving credit to the original source. As an example, see the first post on this blog: HERE, note that the description is 291 words in length.
- Should two students find and post the same article/story, regardless of source, the first student who posted the article/story in the comments will be considered.
- Lastly, this extra credit can only be received once by an individual student.

Sponges have all the genes necessary to have a nervous system, however they do not contain neurons at all. Research done on sponges has led to shocking discoveries of how the nervous system and gene expression are linked.

Anemones and clown fish have a benefitting relationship where the anemone serves as shelter and the clown fish helps the anemone to breath with the "wiggle dance." Previous studies made it blieved to be a one way relationship between the two, but new studies have opened a new look to the two way street.

The gonad is well known for being helpful with reproduction but at the same time it has cut animals life spans down. Planck just recently discovered though that there is a molecular switch that can extend an animals life span using components of a developmental clock. Dafachronic acid activates microRNAs, which work as little molecular switches causing changes in gene expression that promote longer life span.

Evolutionary Biology: Researchers Solve Toll-Receptor Puzzle
Toll-receptors have recently been discovered to identify germs and control the bacterial colony of organisms. Therefore, cnidarians can be a model organism for human immunology research.

Can a Jellyfish Unlock the Secret of Immortality?

Turritopsis dohrnii, or the Immortal Jellyfish, are studied by fascinated biologists. At any stage of development, this species of jellyfish is capable of transforming itself back to the polyp stage, which is the earliest stage of life. Biologists continue to study this creature’s capability of aging in reverse. Afterall, “There’s a shocking amount of genetic similarity between jellyfish and human beings,” said paleobiologist Kevin J. Peterson.
