Dear Scientists,

i got to work with some HeLa cells today!

as cool of an experience as this was and as interesting as these things are, it’s always important to acknowledge the bad along with the good. Henrietta Lacks’ cells revolutionized so many areas of research, but she deserved so much better.

working with these cells today just really reminded me of the duality of many scientific developments. many things have come with great cost and harm and i think that’s something important to keep in mind.

if you aren’t familiar with the story of Henrietta Lacks, i highly recommend looking her up. there’s a book about her live (the immortal life of henrietta lacks) that’s very illuminating.

Antibodies are the secreted form of B-lymphocyte receptors and are a part of adaptive immunity, but how are these proteins formed?

Above is a diagram illustrating Paul Ehlrich’s Side Chain Theory of Antibody Formation. Ehlrich proposed that immunoglobulin molecules, a fundamental component of adaptive immunity, served as membrane bound proteins that bound to particular threats, similarly to the former “key in lock” view of enzymes in catalyzing biological reactions. Ehrlich also suggested that the action of binding a pathogenic molecule to the receptor would generate a signal to stimulate the production of more receptors of the same specificity. These “side chains” that were added on would then break off from the cell surface and become what we call antibodies.

 We now know, however, that soluble immunoglobulin receptors are specially manufactured to be secreted as antibody, rather than just “breaking off” of the lymphocyte, even though they have the same specificity as their membrane-bound counterparts.

i found another specimen of a super rare organism yesterday!

this is a rare and remarkable ciliate, a single-celled organism called Metopus verrucosus.

a few neat facts about it:

it’s an anaerobic organism! this means it prefers to live without oxygen

it lives deep in the mud of sulfur- & methane-rich bodies of saltwater. this one was found in the salt marsh estuary on the side of the garden state pkwy in south New Jersey!

it couldn’t survive in these noxious conditions by itself, though! the fuzzyness covering it’s cell is actually a type of bacteria that symbiotically lives on M. verrucosus.

this bacteria has the ability to metabolize sulfur and/or methane, processing these volatile stinky chemicals and turning it into energy, that it then shares with M. verrucosus!

i’m the only known person with this kind of footage of M. verrucosus! the paper The Santa Barbara Basin is an Oasis of Symbiosis has the only other photo i’ve seen of this organism, and it’s actually an HVEM (electron microscope) photo of a cross-section of the cell showing it’s endosymbiotic bacteria.

here are some more photos i took of other specimens:
