Life of the Immortal Jellyfish (Turritopsis nutricula)

The immortal jellyfish is the only confirmed example of an organism that can theoretically live forever. Studies in laboratory conditions have shown that injured adults can transform themselves back into their polyp stage of development. They are not true jellyfish (class Scyphozoa), instead belonging to the related Hydrozoa class. 

Hydrozoan Life Cycle 

When the egg and sperm of an adult meet, they form free-swimming larvae known as a Planula. This searches for a firm substrate to attach itself onto, and develops into a polyp.

During the polyp stage, the hydrozoan reproduces asexually. It forms Medusa buds, which detach from the polyp and develop into free swimming adults that resemble the conventional jellyfish.

Discovery of Immortality

In 1988, a young German marine-biology student, Christian Sommer, was conducting research on hydrozoans in the Italian city of Rapallo. Sommer  gathered wild specimens and grew them in petri dishes to observe their reproductive habits. He observed that one species appeared to refuse to die, instead aging in reverse until it reached its polyp stage, when it started to grow again.

Fascinated by Sommer’s observations, several scientists in Genoa continued to study the species. In 1996, they published a paper titled “Reversing the Life Cycle”. Further studies since have revealed the Immortal Jellyfish’s rejuvenation process.

Reversing the Life Cycle

The process happens when an individual is injured or stressed. The cells of the jellyfish undergo a process known as cellular transdifferation, by which one type of body cell changes directly into another type of body cell.

In the first stage, the jellyfish sinks to the bottom, where its body folds on itself. The tentacles and bell degenerates until it resembles a gelatinous ball.  Over the course of a few days, this ball forms an outer “shell”, continuing to develop stolons (root like structures). These stolons grow and develop into polyps, thus restoring the jellyfish to its early stages of development. The polyp can then continue the life cycle, forming more adult medusae.

This process has only been observed in the laboratory as encountering and capturing the whole process in the field is extremely unlikely. In the wild, an injured adult may be eaten before it can rejuvenate itself. It is also improbable that an individual can avoid predation and disease for successive generations to live forever.

The Intricate, Beautiful Patterns of Civilization Seen From Above

umans love to tease signals from noise. We see a man in the moon, Mother Mary in a piece of toast, Lady Luck in a winning run at the casino. Alex MacLean deftly plays to this tendency in his stunning aerial photos that reveal patterns in seemingly mundane things.

MacLean leans from the window of an airplane to snap tightly arranged photos of urban, industrial and wild environments. The vantage point is low enough to make out the people and places on the ground, but high enough to see their organization within the broader landscape. His photos provide our appetite for patterns several layers of interpretation to chew on, while exploring the impact of things like urban sprawl, pollution and resource extraction.

“Through sort of abstract and engaging patterns, those things will draw people into it, and hopefully think about these issues,” he says. “It really is about combining art and information. Some of it is sort of subliminal–you can’t quite put your finger on it but it sort of draws you in and engages you.”

Quick update re: how my life is falling apart:
One of my essays is now 4 days late because I still don’t understand what it’s about.
My parents are no longer speaking.
The college has a debt collection agency, and I have come into aquaintence with them in the recent past. Obviously not good.
Two of my best friends have respectively decided to up and out of my life. Because, you know, I have committed irreparable wrongs which are SO GRIEVOUS that they won’t take the time to tell me why they’re angry at me.
I had two panic attacks in the space of 10 hours yesterday.
I honestly cannot find any solution to any of the above problems except the essay.

Interesting child abuse poster

A poster made by The Spanish organization ANAR Foundation (Aid to Children and Adolescents at Risk). They started a new street poster campaign that uses the process of lenticular printing to secretly send a message to abused children without alerting their abusers, even if they’re walking together. 

Anyone over 4’5” sees this view, with a caption: “Sometimes, child abuse is only visible to the child suffering it.”

Anyone shorter sees the beaten child version of the poster with another caption saying: “If somebody hurts you, phone us and we’ll help you.” 

I love this. This is brilliant.

Wow
