Princeton Eggs

Art Bell and Princeton Eggs.As an assistant professor in the University’s Department of Molecular Biology and at the Lewis-Sigler Institute for Integrative Genomics, Princeton Eggs,Murphy wouldn’t be caught dead saying she is doing anything as dreamy as discovering the fountain of youth. She is an award-winning scientist working in the competitive world of molecular biology, and her specialty is hermaphroditic worms.

But her Princeton Eggs work examining the life cycle of roundworms known as C. elegans is taking her into uncharted territory. Understanding the genetic mechanisms controlling the beginning and end of a lifeform’s reproductive capability could lead to learning how to exert control over it. What if reproductive life could be extended indefinitely? Can other signs of aging — memory loss, slackening muscles, even wrinkling skin — be similarly undone?

Wow here is the actual (10 minutes lapse of time) of what is currently happening at each egg site. Boy lots of red in these. Something must be amiss in the world. Lots of activity.Every time I hear Art refer to this, I make a mental note to research this further, but somehow kept forgetting, or ran into roadblocks or something. I've been meaning for YEARS to find this website!

Molecular biology beckoned to her as a field with many mysteries begging to be solved. “There are lots of questions that haven’t yet been asked, and the answers to these are accessible,” she said. “That’s amazing. The idea that you could do this and learn something new was overwhelming to me.”

She also learned to use RNA interference technology, another princeton eggs powerful new technique that worked extraordinarily well in the genome of roundworms. Silencing the function of a gene in this way sometimes can allow a researcher to infer what the function of that gene may be.

This work already has led them to discover a genetic pathway in roundworms that doubles the span of their reproductive lives and produces eggs that lack the genetic problems often seen in the eggs of aging mothers. Such work could ultimately lead to a drug that could help women.

  1. At any rate, I think you will like many of the vadlo biology cartoons!
