biological-immortality

Live water mount of Hydra (left) capturing its Daphnia prey (right).

Fun Fact: Hydra are biologically immortal, meaning they appear not to age or die of old age.

let’s discuss possible endings for rachel duncan.

1. immortal. on the island. her nemeses have been vanquished, she has triumphed. neolution is hers. the experiment continues.

2. joins clone club to fight against neolution. overcomes 20+ years of animosity.

3. tentative ally to clone club, see: point four. 

4. rebels against neolution once she figures out susan was right: she is owned, she is their property, rewriting the laws won’t mean anything. rachel takes neolution down with her.

5. the one known clone not to get the cure. rachel withers away. she dies.

6. imprisonment? 

7. imprisonment after somehow becoming biologically immortal.

8. killed by helena.

9. killed by sarah.

My prediction for the finale is that Jack will kill Aku, but be unable to return to his time, so he instead uses his newfound biological immortality to right the eons of evil Aku caused.

I’ve been feeling like that might be what will happen. The comic touched on this and the message they delivered through that was really important. You can’t change the past, but you can work harder for a better future. Questioning what could have been will just leave you tortured (like Jack is right now).

Attention Sanvers Fanfic readers...

Hey would anyone be interested is reading an sanvers au where Maggie becomes biologically immortal and lives through most of the century, dating Kate Kane, having Jason Todd as a son, before meeting Alex, her final love? Reply or message me if this is something you’d read and I will give it a shot.

Twenty-four going on immortal, biologically woman, sectoral heterochromia (one of my eyes is green, the other is green and brown.), ginger kid. Medical student, future neuroscientist. I'd take you for a whisky and we'd chat about the Byzantine empire..

…are you serious? Truly?

my concentration for my classics major was the Byzantine Empire. I legit own an entire shelf of history books about the Basileion Romaioi

I mean I’m not saying I might be in love, but I might be in love….

Sometimes it seems really strange to me how much of “transhumanism” is focused on biological immortality. For me, transhumanism is almost entirely about trans people and otherkin and tulpas and multiple systems and neurotypes that haven’t yet been named and neurotypes that don’t yet exist and making your body a garden. It’s about all the weird monsters getting to be as weird and monstrous as they want.

And then I see people calling themselves transhumanists who just want to keep doing what they’ve been doing, but for longer. And my gut reaction is, well, I guess that’s a worthy goal. But it’s not very #aesthetic.

I got some hydra polyps in one of my samples from the lake outflow stream. Hydras are super cool. They’re predatory, multicellular organisms that belong to the same class as jellyfish. Back in the late 90s, hydras were the focus of a study that concluded that they were biologically immortal because their cells don’t age and they can regenerate indefinitely if one of their tentacles is lost.

‘Immortal’ Cells:  Is It Biologically Possible For Humans To Live Forever?” from the HuffPostScienceYT Youtube channel.  Host Cara Santa Maria discusses “biological immortality”.  Any creature that is biologically immortal will never die from old age alone.  Is it possible that scientists may soon be able to prolong the life of cells or prevent cellular aging all together?  While some are skeptical, there are those who believe human immortality maybe become a reality within only a few decades.  Would you live forever given the chance?  It may be strange to think that this could become a choice that people are able to make in the near future.

Lengthening telomeres

The phenomenon of limited cellular division was first observed by Leonard Hayflick, and is now referred to as the Hayflick limit. Significant discoveries were made by the team led by Professor Elizabeth Blackburn at the University of California, San Francisco (UCSF).

Advocates of human life extension promote the idea of lengthening the telomeres in certain cells through temporary activation of telomerase (by drugs), or possibly permanently by gene therapy. They reason that this would extend human life because it would extend the Hayflick limit. So far these ideas have not been proven in humans, but it has been demonstrated that telomere extension has successfully reversed some signs of aging in laboratory mice [14][15] and the nematode worm species Caenorhabditis elegans.[16] However, it has been hypothesized that longer telomeres and especially telomerase activation might cause increased cancer (e.g. Weinstein and Ciszek, 2002). However, longer telomeres might also protect against cancer, because short telomeres are associated with cancer. It has also been suggested that longer telomeres might cause increased energy consumption.[13]

Techniques to extend telomeres could be useful for tissue engineering, because they might permit healthy, noncancerous mammalian cells to be cultured in amounts large enough to be engineering materials for biomedical repairs.

That the role of telomeres is far from being understood is demonstrated by two recent studies on long-lived seabirds. In 2003, scientists observed that the telomeres of Leach’s Storm-petrel (Oceanodroma leucorhoa) seem to lengthen with chronological age, the first observed instance of such behaviour of telomeres.[17] In 2006, Juola et al.[18] reported that in another unrelated, long-lived seabird species, the Great Frigatebird (Fregata minor), telomere length did decrease until at least c.40 years of age (i.e. probably over the entire lifespan), but the speed of decrease slowed down massively with increasing ages, and that rates of telomere length decrease varied strongly between individual birds. They concluded that in this species (and probably in frigatebirds and their relatives in general), telomere length could not be used to determine a bird’s age sufficiently well. Thus, it seems that there is much more variation in the behavior of telomere length than initially believed.

What made me smile this week:

Sunday: We had a family dinner for my mom’s birthday today (everyone say happy birthday Sue!). While we were all sitting around enjoying each other’s company, my baby cousin Luke—who has just recently started walking—began to dance to the beat of a song that was playing on someone’s phone. I say “dance,” but he really just stutter stepped in circles with an enormous grin on his face. It made me smile.

Monday: Today I learned that lobsters are biologically immortal. Now, since I know nothing about science, I’ll probably explain this incorrectly, but basically: Lobsters have some special chemical that revitalizes their DNA, causing them not to age. The only natural reason lobsters ever die is because they grow too big from a lifetime of food consumption and are unable to defend themselves or effectively hunt for food. I thought that was mind-blowing and it made me smile.

Tuesday: I learned something slightly less incredible, but equally as mind-blowing today. While riding along with Sarah to pick up her wedding dress, I learned that brides typically purchase their wedding dresses. I was living under the false assumption that wedding dresses were rented. Sarah found my stupidity hilarious, which made me smile.

Wednesday: For a while, people have been telling me I need to wheel my ass over to Mitzi’s Table in Bethlehem. Well, this morning I finally had an opportunity to grab brunch at Mitzi’s with the almost-not-Burcaw-anymore Sarah. That was about two hours ago and I am still fully immersed in a full-body euphoria unlike anything I have ever experienced. The staff was as welcoming as family (turns out, they are LAMN followers!), the interior was cozy yet wheelchair friendly, and best of all, the food was unbelievable. People often overuse that word, but I literally could not believe how my scallion cheddar biscuit melted in my mouth, or how the zingy pepper hollandaise sauce complemented my perfectly poached eggs Benedict Florentine. It changed my life, and it made me smile.

Thursday: Friends of mine will tell you that I have a weird obsession with blue foods and drinks. Tonight, I ordered a blueberry mojito while out with my friend Michaela, and it was the blue-est blue I’ve ever seen. It made me smile.

Friday: Oh no, all my smiles are about food again. At Sarah’s wedding rehearsal dinner tonight, my brother assisted me in the buffet line. One of the dishes was beef tips over mashed potatoes, and since mashed potatoes are my life-source, I asked Andrew to load up my plate with a heaping mound. I was so excited. When I got back to my seat and took the first bite, I discovered they were grits. Whomp whomp. Oh well, it made me smile.

Saturday: Sarah’s wedding was today. It was an evening full of love and laughter, and I could not be happier for her. During the bridesmaids’ toasts, her sister Becca said something that really stuck out to me. While discussing her idea of love, she said “Love breaks the silent treatment before it is earned.” Such a simple, yet powerful idea! Love conquers all. It made me smile (and possibly tear up a little bit).

What made you smile this week?

One of my recent projects involved illustrating the Lifecycle of Turritopsis dohrnii, commonly known as The Immortal Jellyfish It is the only known species of an animal capable of reverting completely back to polyp stage making it seem biologically immortal. Is it really though?
