Once again, the eyes have it
The Reed College Developmental Biology class from Fall 2022 investigated all kinds of questions this year ranging from how fertilization happens in a variety of species to multiple independent projects examining the formation of facial features, heart development, eye and brain growth and development, and regeneration. We mostly performed experiments with zebrafish (for the optically […]
RETURN OF THE DEV BIO IMAGE CONTEST!
After a two-year hiatus, Developmental Biology (BIO 351L) at Reed College is back — in person and imaging lots of zebrafish embryos. This year’s image contest featured 9 entries from 7 students. Thumbnails of all the entries are below. All images were captured with light microscopy by undergraduates who investigated cell proliferation, the expression of […]
Published!
Elation, excitement, relief, pride. Work that was begun more than 5 years ago has finally seen the light of day! We still have many questions, but our current insights into how two extrinsic signals – Gdf6a and the retinoic acid (RA) – influence the transition from proliferation to differentiation in the vertebrate eye is now published in Development. […]
Cerveny Lab at the Murdock College Science Research Conference
The Cerveny Lab represented Reed College at the annual Murdock College Science Research Conference on Novemember 14-15. Three students – Wilson (Will) Horner, McKenzie Givens and Alison Bryant – presented the results of their summer research. We engaged in great scientific discourse with 34 oral presentations and 221 poster presentations from students at 31 institutions […]
We have EMBRYOS!
I had planned to show off my dissecting microscopes attached to their brand new transmitted light bases in this post, but I have something even better. The first embryos from our facility were born this Thursday morning! Now that the water quality seems to have stabilized with ammonia levels back to zero, I’m hopeful that […]
Science Savvy October 11th, 2012
How do we know when science, or a particular experiment, is right? We all have fallen into to the trap of thinking of science as a static body of knowledge. We all had/have large textbooks, giving the appearance of monolithic science with a capital “S”. Those of us who are scientists, or have friends who […]
Science Savvy October 5th, 2012
Who knew that metaphors for biology could include the likes of The Odessy, babybel cheese AND Angelina Jolie’s lips? Check out the latest Science Savvy, entitled “Brain Origami” and gain a (new) perspective on the processes that generate eyes. Navigate to The Quest, or you directly to the article. And for those who wanted to […]
Science Savvy September 28th, 2012
The third installment of Science Savvy is now in print! If you can’t access a paper copy, you can read the online version on the Quest site. We’ve also reprinted the text below with some external links to cool movies and the original articles. We hope you enjoy this article and will appreciate this example […]
Our First Science Savvy
The first full-length Science Savvy Column is out in this Friday’s Quest! If you want to read the full paper that is discussed, you can download it here. You can also read the first summary of this paper that I wrote while still a post-doc by clicking this link. Hope you enjoy the column. If […]
Specification and Morphogenesis Wnt Together in the Eye Field.
For our Developmental Neurobiology Seminar this week, we discussed regional patterning within the forebrain, focusing on the role of Wnt signaling in eye field and diencephalon specification. We read and talked about a 2005 Neuron paper, entitled “Early Stages of Zebrafish Eye Formation Require the Coordinated Activity of Wnt11, Fz5, and the Wnt/β-Catenin Pathway. The […]
