Jellyfish Central

Jellyfish Central is my ongoing collection of articles, research and thoughts on  jellyfish and invertebrate.

Jellyfish captured my attention and imagination in the mid-1980s, about midway through my fifty-year career in vision research. At the time I was chief of the Laboratory of Molecular and Developmental BiologyNational Eye Institute, National Institutes of Health (NIH) in Bethesda, Maryland. My specialty was gene expression in the eyes of vertebrates.

While reading a new book on invertebrate vision, I learned that complex jellyfish eye looked like a variation of the highly evolved human eye!

It appeared to me that Jellyfish eyes seemed much more than evolutionary stepping-stones to vertebrate eyes; they were small jewels.

I suddenly, impulsively, wanted to study jellyfish eyes. Stepping into the strange universe of jellyfish resonated with the excitement I had in choosing a career in biology many years earlier. But where to start?…

Fiction Earns, Science Reveals

While some might insist that science is strictly factual, I think most would agree that speculation links discrete scientific data – facts – resulting in a narrative that becomes modified with additional data and knowledge. Speculation is not factual. In that sense, I view science as partly fact and partly story, and propose that reality [...]

Do Invertebrates Have Minds?

Recently Ricardo stepped out of Jellyfish Have Eyes looking for tell-tale signs that his troubles with science in the mid- 21st century were sinister developments of earlier times. As he suspected, he found an article in The Washington Post that he believed foreshadowed the demise of ivory-towered basic research. I remember that he looked depressed [...]

Ricardo Pops Up and Speaks

Ricardo’s back and apparently in a talkative mood. I want him to remain at this website for a little while, but he said that there’s a website for Jellyfish Have Eyes (jellyfishhaveeyes.com) where he plans to settle in. That’s his real home. However, he’s happy to speak out in both websites for now so that he [...]

Dead and Alive: Ricardo Plans to Break Loose

Writers are both atypical midwives and partial parents to their characters. As atypical midwives, they deliver babies of every age in the form of words. As partial parents, they give a sliver of themselves to each character, selected genes from the author’s repertoire, not their whole genome. When the book is finished – the story [...]

In his classic The Sense of an Ending (2000), the literary critic Frank Kermode discussed the idea that scientists connect discrete observations as a form of “concord-fiction.” He used Heisenberg’s uncertainty principle – that electrons possess the mutually exclusive properties of waves and particles – as an example. How can we conceptualize an electron as [...]

NEI Scientist Emeritus’s Debut Novel Probes Jellyfish Eyes

By |2020-04-02T21:57:00-04:00July 3rd, 2015|Categories: Blog, Jellyfish Have Eyes!, Joram Piatigorsky Book Reviews|Tags: , |0 Comments

By Kathryn DeMott, NIH Record: NEI scientist emeritus Dr. Joram Piatigorsky remembers the moment he became captivated by jellyfish eyes. He was reading a book about invertebrate vision and there it was—an image of a very familiar-looking eye looking back at him from the most ancient multi-organ animal. The eyes of jellyfish became a focus of his more than four-decade long career at NIH.
