Chromophore Formation in the Green Fluorescent Protein

dgurnon — Fri, 22 May 2009 13:53:11 -0700

This animation depicts the reaction of a 3-amino acid sequence within GFP to produce a cyclic chromophore, the source of the protein's fluorescence. The starting conformation and finished cyclic chromophore are representations of actual crystal structures of GFP. Created using UCSF Chimera, Autodesk Maya and Adobe After Effects software.

Regulatin' Genes

tomcfad — Mon, 18 May 2009 15:10:49 -0700

This parody of Jay-Z's "Money Ain't a Thang" explores the wonderful world of developmental biology. Made for Human Biology 3A at Stanford University. Lyrics (shown below) by Tom McFadden, performance by Tom and Derrick Davis, cameo by Bob Siegel, and edited by Jake Wachtel.

Derrick:
In the dorsal or ventral, making proteins,
Top down - secreting out, regulatin’ genes.

Tom:
Here we go in the embryo - asymmetry.
From the egg sac, holler back regulatin' genes.

Jigga I don’t like it if it aint zinc finger
or homeodomain, yo, regulatin’ genes.

Synaptic Cleft

tomcfad — Fri, 15 May 2009 16:43:37 -0700

This parody of Wu-Tang Clan's "Gravel Pit" was made for Human Biology 4A's unit on Neuroscience. The unit is taught by Russ Fernald (who is featured on his bicycle). Lyrics are below, followed by the cast. Video edited by Jake Wachtel.

SARAH TONIN (Chorus): Check out the synaptic cleft.
where, thanks to vesicular trafficking,
a neuronal signal can be transmitted
from electrical to chemical and back again.

METHYL MAN: Ha! Enter into the land if the nerve, where firing of wiring will occur.
Follow me. Neurons gotta be... ready to fire at any opportunity.

Pressure bomb

schulzbu — Thu, 14 May 2009 21:09:28 -0700

This video is a visual 10 step instruction manual how to use a pressure bomb for measuring water pressure in the xylem of transpiring leaves. It is geared towards undergraduate students working in plant physiology labs as well as viewers who are interested in plant biology.
Water in the xylem is under negative pressure. This tension can be measured by a “pressure bomb”. Tension pressure in a non-transpiring leaf is “equivalent” to water potential of cells surrounding the xylem (mesophyll cells), because the xylem’s osmotic potential is negligible.

Aggregation of mouse fetal cells on a NAN nanofiber insert.

Arjumond — Thu, 14 May 2009 11:03:33 -0700

Visualization of the formation of multiple small punctate areas of aggregation across the surface of a NAN nanofiber insert. Early passage mouse fetal cells in suspension were injected into a Sykes-Moore chamber containing a NAN nanofiber insert. The cells attached to the nanofiber insert and were observed for seven days using time-lapse videomicrography.
Cell cultures growing on NAN nanofiber inserts behave differently from such behavior on SAN nanofiber inserts, both of which provide a more in-vivo like nanotopography compared to plastic.

Time lapse videomicrography of the life cycle of Dictostelium

Arjumond — Thu, 14 May 2009 10:47:03 -0700

Distinct stages of Dictyostelium discoideum life cycle can be seen. As the video starts there is a wave of bacterial growth across the agar. From the implantation site of the spores, you can see the myxamoeba migrating out consuming the E.coli. As the E.coli is consumed you can see a clearing in the agar after which the myxamoeba using chemical signaling form multicellular slugs. The slugs can be seen migrating across the field of view, with the formation of a sorocarp in the upper right hand conner of the screen, indicating the end of the life cycle.

Aggregation of mouse fetal cells on a SAN nanofiber insert.

Arjumond — Thu, 14 May 2009 10:31:55 -0700

Visualization of the formation of one large amorphous cell aggregate migrating across the surface of a SAN nanofiber insert.
Early passage mouse fetal cells in suspension were injected into a Sykes-Moore chamber containing a SAN nanofiber insert. The cells attached to the nanofiber insert and were observed for seven days using time-lapse videomicrography. Aggregation of a cell monoloayer into one large globular cell aggregate which migrates across the field of view, as observed with 10X and 40X phase objectives.

The Well Dressed Ape book review

sciencegoddess — Tue, 12 May 2009 10:54:04 -0700

Joanne describes her listening experience of the audio version of life-science-popular-book-writer Hannah Holmes' "The Well Dressed Ape: A Natural History of Myself" as the more comprehensive and funnier updated version of the 1960s "The Naked Ape" by Desmond Morris. Joanne's goal with book reviews is to be positive and intelligent and encourage the reluctant science reader to pick up a book and to let science enthusiasts know what is available on the bookshelves now.

The nature of cell science

Pacho — Thu, 16 Apr 2009 04:31:37 -0700

Certainly it´s irony in the title, because these images never made it to publication status.
Sitting over the microscope, whilst listening to music the idea popped up to combine
microscopic imagery with electronic music. The Scientist will certainly see more than
a carpenter, but both might enjoy the beauty. Concerning the used music, it is
Venetian Snares (oh another biological toppic) "Szamar madar", a masterpiece (in my ear)
in blending classical music with electronic break core music.

enjoy.
