Whispers from the Sea Tanzelle Oberholster Storm Nature Finding Yourself Survivor Rebirth Transform Willpower Warrior Mind Frame Shift andDNAsci.wordpress

Shouting into the storm

Swallowed by my fury

Spilling onto the floor

All I was no more

 

How can you tell

where the pieces have fell

lost between the cracks

there is no turning back

 

The sound of waves crashing clear

as I leap into my fears

a plunge into the deep

into every essence they seep

 

Something standing so near

but to turn they simply disappear

the void loudly beckoning

yet I have had no reckoning

 

Through the darkness you must wonder

to see the light that shines over yonder

however free of shades I may be

their ghosts still cling to me

 

Scars carved into my soul

filled with water to flow

into the great sea

where I needed to be

at night they will glow

and

lead me to places that only I know

A Cat's Point of View Cat Eyes Perspective Opinion Rat Race Tanzelle Oberholster Mind Frame Shift andDNAsci.wordpress

 

From behind these yellow eyes

I watch humans chase after lies

Back & forth you rush for days

All in your futile little rat-race

You are constantly filled with rage,

since you have not found the keys to your cage

But true freedom can only grace

those who look beyond another’s face

How much more simpler your lives would be

If you only had the insight to see

That the value of life doesn’t solely rest

upon those who can only perform the best

 



Publish or Perish

  They all would deny how they readily rely on egos drenched in pride and that it’s all built on lies   Several tools at their disposal all with which to exact reprisal against those who dare refuse to be hung by their dreadful noose   Bullies, cowards and theives they belittle and steal your … Continue reading Publish or...

They all would deny

how they readily rely

on egos drenched in pride

and that it’s all built on lies

 

Several tools at their disposal

all with which to exact reprisal

against those who dare refuse

to be hung by their dreadful noose

 

Bullies, cowards and theives

they belittle and steal your dreams

then laugh at you foolish beliefs

vehemently refusing reprieve

 

Values and morals it abhors

sick, twisted and corrupted it distorts

not allowing science to thrive and explore

because nobody cares anymore

 

Cannibalistic social tendencies

have become a cultural dependency

yet some hope still clings stubbornly

for education to once again become the priority

 

Purging the scourge

will allow science to reemerge

and reclaim its singular purpose

to lead humanity to its rebirth

POI Persons of Inspiration Encouragement Dreams Enlightenment Tanzelle Oberholster Mind Frame Shift andDNAsci.wordpress

 

Sometimes in life, especially during dark times

someone, be it through a spiritual guide or divine intervention,

sends you a person of inspiration.

 

Their timely arrival may seem serendipitous,

a strange working of synchronicity.

 

They meet you during a chance encounter at the mall

or you happen upon their post in the ‘recommended’ section of your reader.

 

They speak the truth.

 

Words you need to hear,

not what you want to hear.

 

The message is delivered by kind hands

and

accompanied by strong encouragement.

 

To remind us that fulfilling dreams don’t always come easy,

else everyone would already be enlightened.

 


Thank you to all my earthly angels and spiritual messengers who stood with me at the abyss!

Persons of Inspiration: May we find them, may we know them and may we be one of them!

La Sonadora The Dreamer Enya Lyrics Translated English MindFrameShift Tanzelle Oberholster andDNAsci.wordpress

 

I; the autumn
I; the evening star
I have been an echo

I shall be a wave
I shall be the moon
I have been everything, I am myself

I; the summer
I; the ebony
I am the dreamer

 

 

Yo; el otono
Yo; el vespero
He sido un eco.

Sere una ola
Sere la luna
He sido todo, soy yo.

Yo; el verano
Yo; el ebano
Soy la soñadora.

Life after Death? Where Nature, Science and Art meet

The preservation of singular cells has been possible for quite some time. In science, we regularly freeze bacterial cells in the laboratory for long-term storage (at -80oC with some sort of ‘biological’ anti-freeze, like glycerol).

The preservation of singular cells has been possible for quite some time. In science, we regularly freeze bacterial cells in the laboratory for long-term storage (at -80oC with some sort of ‘biological’ anti-freeze, like glycerol). In medicine, the freezing of human cells, such as bone marrow, blood and reproductive cells is common practice. However, our fascination with life after death and the advances in technology has led to the idea of freezing entire human bodies – with the hope to someday revive them.

Cryopreservation Freeze Storage Freezing Cryobiology Neuropreservation Human suspended animation
I couldn’t find free images of cryogenic pods (not even space pods), so I had to make do with what I got – LOL!

 

There are companies specializing in the cryopreservation of human bodies, such as Alcor (REF 1). Members of these companies are placed on a ‘watch-list’ and when their time draws near, a medical team is on stand-by to swoop up your body (or brain) when you are declared legally dead. It is preferable to get your body into deep freeze (-196oC) as quickly as possible to lessen the effect of bodily decay. They pump your body full of a cocktail of chemicals to preserve the tissue and prevent ice crystals forming inside the cells (termed cryoprotectant perfusion). Your body is cooled gradually to prevent thermal stress and fracturing. You can read about the entire procedure on Alcor’s website, including a cryopreservation protocol with a step-by-step explanation. As you can imagine this service is also very expensive.

The idea behind such a service is that you would freeze your body with the hopes that future technological/biological advances would be able to revive you. It’s the fountain of youth principle in a quest for immortal life… It might sound a bit like science fiction, but there are several cases of freezing and successful resuscitation in the animal kingdom. For example in:

  1. Insects and Invertebrates: Freeze-tolerance has been extensively studied in insects and invertebrates, such as nematodes (Panagrolaimus davidi), inter-tidal molluscs and earthworms. These species rely on build-in cryoprotectants to ensure cellular integrity (REF 2).
  2. Amphibians and Lizards: The Wood Frog, Rana sylvatica synonymous Lithobates sylvaticus, is a freeze-tolerant frog inhabiting areas in Canada, Alaska and the Arctic Circle. Unlike some invertebrates that require ice-nucleation proteins in their haemolymph, the wood frog has gut bacteria that act as cryoprotectants (along with glucose). (REF 3)

However, there are several limitations to the freezing of living animals (Table 1):

  • Generally, the body of the organism needs to be frozen gradually and the larger the animal, the longer the freezing process. Few organisms can tolerate sudden/snap freezing (REF 2 & 3).
  • Few animals can withstand extremely low freezing temperatures, the general limit sits at ~ -2oC, whereas the nematode (P. davidi) has been recorded to survive up to -80oC (REF 2).
  • No organisms can tolerate whole-body freezing, about 50-75% of the body can be frozen at once depending on its size (the larger  the organism, a lesser percentage) (REF 2 & 3).
  • Finally, no living organisms can be frozen indefinitely (the wood frog can go for up to 4 weeks in a semi-frozen state) (REF 2 & 3)

Table 1: The freezing characteristics of some freezing tolerant animals.

 

These limitations are imposed due to the fact that the animals are still alive when frozen. Metabolic processes within the cells do not cease, they just slow down tremendously. These active cells still require oxygen and the expulsion of waste products. When possible, freeze-tolerant animals will increase their metabolism and/or temporarily awaken to flush out toxins. Also, due to the fragile state of the organisms during freezing, they are susceptible to freeze – and mechanical cellular damage. This is one of the reasons why you should remove your E. coli cells from deep freeze storage, re-grow them and then re-freeze them again.  However, organismal revival is possible due to the fact that the organisms were alive before undergoing cryopreservation. Thus, I wonder how exactly one would ‘revive’ a dead body?

I am going to touch upon some macabre topics of bodily decay and putrefaction, but don’t worry I am not going go all CSI with the gory details! As with living cells, which do not cease to be metabolically active, dead cells do not cease undergoing decay. Bodily putrefaction is mainly driven by the gut bacteria in the human body. Hence, why the Ancient Egyptians removed body organs, packed the cavity with sand bags and placed the individually preserved organs in pots, separate from the preserved body, in the sarcophagus. They believed that the deceased person’s soul would still require their body and organs once they reached the afterlife (but apparently the organs needn’t be in the body!). This leads me to the next question(s), if the body has died and you can somehow revive it – would the ‘consciousness’ and/or ‘soul’ of the person still be there?

Time Travel Space Cryopreservation Freeze Storage Freezing Cryobiology Neuropreservation Human Tanzelle Oberholster andDNAsci
I suppose that cryopreservation or cryostasis would be much like time travel…

 

Maybe you would be able to get the body functioning again, but would the person still remain? I mean it’s all fine and dandy to pay away your future earnings, retirement fund and/or children’s inheritance for a life-extension service – it is your business after all… but what if you are not preserved along with your body? I know that some people think that we as a persona are merely electrical signals firing in the brain and that neuropreservation should cover that, but if we are so susceptible to damage while frozen – it is not impossible to predict that you too would be damaged somehow during the process. Also, where did you go or what did you do while you were waiting for your body to reanimate again? Would you simply perceive the process as a very long period of sleep? Or even be trapped in those ‘near-death’ experiences, either good or bad? Would you be able to adapt to the ‘new futuristic world’ once you wake up? Would the futuristic people even want to or allow you to be resurrected? This is what I wonder about when I see these types of services advertised or when they are featured during TV detective stories. These questions would also be especially important if you believe that there is more to life than just our present worldly human experience, or if you at least can acknowledge that we cannot definitively know or not know…

Thus, the preservation of the dead to ensure life for the future would require far more than just fancy science when you go against the tendencies of nature, because preservation of the soul would require a lot more creativity. Therefore, cryopreservation rather becomes more of an Art form than simply pure Science when you take into account the Nature of what it means to be human.
