12 Bizarre Facts About Jellyfish That Will Blow Your Mind

March 29, 2014

1. Some have “immortal” properties.

The immortal jellyfish (Turritopsis dohrnii) ages like Benjamin Button—when a crisis like starvation presents itself, the jellyfish’s cells transform and revert to their earliest form, a polyp, making this type of jellyfish potentially immortal. Keep reading for more incredibly bizarre facts about jellyfish!

2. They have no “sides”.

Jellyfish have no right or left side—only a top and bottom—as they are symmetrical around a central axis that runs the length of their bodies.

3. Jellyfish are a boon to cancer research.

Green fluorescent proteins (GFPs) from the Aequorea victoria jellyfish species have transformed bio-medical research. The glow-in-the-dark proteins can illuminate specific proteins within the human body to track microscopic activity (for instance, cancer growth).

The dirty little secret at the heart of nature is the parasite. For every animal we humans regard as noble—your tigers, your dolphins, whatever—there are thousands of these horrifying little monsters. So numerous are these microscopic tyrants that naturalists believe that an actual majority of animals might be parasites. It’s entirely possible that life on Earth exists solely to provide adequate hosts for our many, many parasites. And you thought looking at a starry sky made you feel insignificant.

Here are five of the weirdest that we know of so far.

Human beings can come to terms with some parasitic diseases. Malaria, for example, is refreshingly straightforward. You get bitten by an infected mosquito, you get sick and you (maybe) die. The parasite is just trying to weaken you to the point that you can’t swat the next mosquito that comes to drink your infected blood. It’s nothing personal.

Some parasites, however, despite being harmless to humans, make their living in such a gothic horror show manner that we really can’t be comfortable sharing a planet with them. Meet Cymotha exigua, the marine isopod that thinks it’s a tongue.

Carl Sagan Writes Neil DeGrasse Tyson

This exchange is the stuff of scientific and cultural legend. When Neil DeGrasse Tyson accepted Sagan’s invitation and spent a Saturday touring Cornell University labs with the famed astrophysicist, his life was irrevocably changed.

A 17 year old when he met Sagan for the first time at Cornell University, Tyson later described the encounter in this way:

“At the end of the day, he drove me back to the bus station. The snow was falling harder. He wrote his phone number, his home phone number, on a scrap of paper. And he said, “If the bus can’t get through, call me. Spend the night at my home, with my family.”

Scientific Heroes: Rosalind Franklin

We all know the scientific greats; Darwin and his theory of evolution, Newton and his laws of gravity. But there are droves of unsung heroes of the scientific world whose works deserve much recognition. Rosalind Franklin is one of them. As a molecular biologist, Franklin was responsible for the original research behind the discovery of DNA’s structure.
