Biology Clips, Stills & Slides - View Xenopus Development

In summary, the website has some really neat Clips, Stills, and Slides of small life forms. The video illustrate, how perfectly times embyonic development is, since three three eggs were fertilized at the same time and develop at the same speed. It is cool, since it is a time lapse videa which shows the process from first cell division all the way of the hatching of the tadpole. Too bad the resolution is not so nice, I've got in on a CDROM which is 100x better.

Take a look at this website, it has some really neat Clips, Stills, and Slides of small life forms:

http://www.cytographics.com/Especially nice is the video of Xenopus (toad) eggs. The video illustrate, how perfectly times embyonic development is, since three three eggs were fertilized at the same time and develop at the same speed.

It is cool, since it is a time lapse videa which shows the process from first cell division all the way of the hatching of the tadpole. Too bad the resolution is not so nice, I've got in on a CDROM which is 100x better.

Oh, how wonderful!

I especially liked the "Early Phases of Mitosis", and it's even in quicktime format (which I much prefer).

Very nice sites.

Please feel free top post any website which are great resources or have nice animations!

I've got some more

http://www.becominghuman.org

Which is a documentary made by Donald C. Johanson, an Paleoanthropologist. It is really extensive and lenghthy: nicely made :) Definetely worth listening to.

I really enjoyed this site... I thought the Noctiluca Scintillans was kinda cutesy, with its ability to catch prey with its flagella... I don't know when I see things like this I want to reconsider being a biology major...

That is a really nice tutorial AG, if you know more of these I'd like to know that :)!

I just found two cool websites:

Animated Tutorials
This site is actually of the company which is contracted to make the tutorials, but it seems you can access all of the tutorials that they make. They have many biology ones as well as physics, astronomy etc.

Stem Cell Information
This is the NIH's Stem Cell information website. If you have ever wanted to know anything about stem cells, i think this is a good place to start.

I don't know if this will help, but it has a chapter listing, and one of them might be related to what you want. Often if you can just find one site which is related to what you want, check out the links from that site, and you 'surf'[b(] your way to the site you want.

William Calvin has ~10 books (on neuroscience and evolution) online at http://www.williamcalvin.com/index.html#books (Don't be scared away by the horrible web design, though.)

New evolution 101 site. Should be good - - it's by the National Center for Science Education (heavily engaged in the creation-evolution debate).

http://evolution.berkeley.edu

The Understanding Evolution website -- written for teachers but accessible to the general public -- is intended to provide "one-stop shopping" for evolution education. The website is rich in content, with sections on the nature of science, evolution itself, the different lines of evidence supporting evidence, evolution's relevance to everyday life, widespread misconceptions about evolution, and the history of evolutionary thought. There is also an extensive section especially for teachers, giving advice on teaching evolution, ideas for lesson plans, ways to avoid confusing students, and answering common student questions.

And of course, there is the always famous...

Looking for immunology animations

I'm looking for a site with immunology animations that would be appropriate for students that are either non biology majors or have a very basic understanding of biology. I've looked at a few sites you guys have listed (some very cool sites) but haven't found one that gives a good general overview of the immune response cascade. If you know of good site please let me know!
Thanks

Phylologist's Dream Site

The Tree of Life Web Project (ToL) is a collaborative effort of biologists from around the world. On more than 4000 World Wide Web pages, the project provides information about the diversity of organisms on Earth, their evolutionary history (phylogeny), and characteristics. Pictures of literally everything!

If your into phylogeny,systematics, this is the one! -david

Amazing to see: the development of the C. elegans worm (a model organism) from a single cell to a 558-celled worm in about 14 hours. Watch how the single cell gets divided into many units and how a structured worm is formed (with a functioning feeding apparatus, gut, nervous system and muscles) http://www.bio.unc.edu/faculty/goldstein/lab/celdev.mov

More C. elegans movies: http://www.bio.unc.edu/faculty/goldstein/lab/movies.html

This is a collection of some beautifully photographed plants, and has some good examples for studying as well.

And a whole bunch of cactii pictures. The huge variety and colour that you find in cactii is amazing.

Found this on YouTube:

Pretty funny!:rofl:

I'm new, so if this isn't the right place to post this, please move or delete. Thought it was worth sharing for those into DNA
