Nobel's Prize Day!

On this day (December 10) in 1901, the first Nobel Prizes were awarded on the anniversary of Alfred Nobel's death: for Physiology, Behring (antitoxin for diptheria); for Peace, Dunant (founding the International Red Cross) and jointly Passy; Physics, Röntgen (x-ray), and for Chemistry, Van't Hoff (chemical thermodynamics).

The Nobel committee admitted that one of it's greatest omissions in the history of awarding the Nobel Prize was Gandhi; in 2006 the Secretary of the Norwegian Nobel Committee said "The greatest omission in our 106 year history is undoubtedly that Mahatma Gandhi never received the Nobel Peace prize. Gandhi could do without the Nobel Peace prize. Whether Nobel Committee can do without Gandhi is the question." Gandhi was nominated twice during two separate awards seasons, the second time the year he died. That year, 1948, the Nobel Committee did not award a peace prize, saying "there was no suitable living candidate".

So... who is YOUR favorite winner of the Nobel Prize?
Or who do you think should've got one, and didn't?
Or should get one next year?!?

Maybe that person is you...

[go look up the histories of the Nobel winners... you could be one of them ;)  ]

...next year.. the history of Nobel and the prize...?

Human Rights Day / Week - a celebration we should make last all year...

The U.N. says it so well...

"   Human Rights Day is observed every year on 10 December. It commemorates the day on which, in 1948, the United Nations General Assembly adopted the Universal Declaration of Human Rights. In 1950, the Assembly passed resolution 423 (V), inviting all States and interested organizations to observe 10 December of each year as Human Rights Day.

This year, Human Rights Day calls on everyone to stand up for someone's rights! Disrespect for basic human rights continues to be wide-spread in all parts of the globe. Extremist movements subject people to horrific violence. Messages of intolerance and hatred prey on our fears. Humane values are under attack.

We must reaffirm our common humanity. Wherever we are, we can make a real difference. In the street, in school, at work, in public transport; in the voting booth, on social media.

The time for this is now. “We the peoples” can take a stand for rights. And together, we can take a stand for more humanity.   "

The Coelenterates, A Scientific Controversy...

 

To coelenterate or not to coelenterate, that is the question...

Whether 'tis Nobler in the nomenclature to correlate
The Threads and Barbs of nematocysts,
With the colloblasts of the ctenophores,
And by opposing end their correlation: to declassify, to reclassify
No more; and by classify, to say we reorganize
The Heart-ache, and the thousand Natural shocks
That gelatinous bodies are heir to? 'Tis a re-classification
Devoutly to be wished. To declassify, to reclassify,
To reclassify, perchance to genetically code; aye, there's the rub,
For in that coding, what truth may come,
Comprehending these evolutionary differences,
Must give us pause. There's the respect
That makes Joy of so long life...

(with deepest apologizes to The Bard)


Science is active, it is about observing, testing, considering, and refining. With Science we learn additional information and refine our perspectives, the case of the cnidarians and the ctenophores is an excellent example; Science utilizes the method of using our best-current-facts to comprehend the world around us. Our ability to *see* the natural world around us changes greatly over time due to advancing technologies (microscopes, telescopes, genetic coding, etc.) and of course the effect of standing-on-the-shoulders-of-those-that-went-before (discovery builds on discovery, comprehension on comprehension... ).

E. Haeckel- Cnidaria

To quote- science is "the intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment"... Anyone can do it, but Science demands from the *researcher/observer* open-ness not only to new ideas but to being able to follow the evidence where it leads and acknowledge changes/updates in information.

So... what does this have to do with our coelenterate controversy?

...any excuse for a Haeckel! Ctenophora

Cnidarians (anemones, corals, and jellyfish) and ctenophores (comb jellies) *used to* be categorized in the same Phylum, Coelenterata; both are very simply structured, gelatinous-bodied, and lack a backbone (invertebrate). BUT! research over time (which is *how* research happens : ) has shown that the differences between the cnidarians and the ctenophores are substantial enough to place them in separate phyla: Coelenterata (a.k.a Cnidaria) and Ctenophora; because of some similarities and a history of grouping them together the two phyla are sometimes still colloquially (non-scientifically) grouped together for convenience and called coelenterates (so, be gentle, sometimes change takes time! ;)  ).



So, what are some of those differences which led scientists to go to the lengths of creating a whole new PHYLUM?!?
(and how the heck do you pronounce coelenterate, cnidaria (UK), and ctenophore anyway?!?)

	Cnidarians (Coelenterates)	Ctenophores
Symmetry -body	Radial	Bi-radial
Digestive tract	Incomplete (single) digestive opening, food enters and leaves the body through the same opening	Complete (one way) digestive tract with 2 openings: oral (mouth) and anal.
Prey capture	*Stinging cells- cnidocytes/ nematocysts	Sticky cells- colloblasts
Larval form	Planula	Cydippid
Development	Diploblastic, with true tissue	Triploblastic

(by the way, any terms/words you are uncertain of can easily be found online! I’m in a rush today! : )

*Those stinging cells are key by the way!

It appears that cnidarians are more directly in-line evolutionarily, and that the ctenophores are more of a sibling group to all other animals. Ctenophores have muscle and nervous systems that seem to have evolved independently from other modern animals (google Hox and Homeotic gene contingents!). Where the ctenophores sit in their forms and functions excluded them from being grouped in the Phylum Coelenterata.

So, you see, what some people may think of as a negative, "controversy", Science sees as normal growth and development. We start with basic information, and then, based on observation, testing, and consideration we develop and refine the information. Since our abilities and technologies improve our ability to perceive more of the natural world improves also; consider the path to what we know about genetics ...

Double Helix

...in 1866, the monk, Gregor Mendel published a paper based on his plant experiments (done in the garden of the monastery) that became the basis for the Mendelian laws of inheritance, Meischer published his first paper identifying "nuclein" (now called DNA) in the cell nucleus in 1871 (without the microscope *that* would have been rather impossible), 1900 Mendel's work was rediscovered by several researchers (confirming their work), in 1910 Kossell received the first Physiology/ Medicine Nobel Prize based on the discovery of the 5 nucleotide bases (go google that, it's something you should know!), Hershey and Chase demonstrated that DNA carries our genetic material in 1952, 1953 was the "discovery" of the double helix (yeah, the double helix was always there, but until we could "see" it we couldn't *see* it! ... y'know?), in 1977 Sanger developed a sequencing technique to sequence (read) the first full genome (the complete set of genes in an organism), 1990 saw the launch of The Human Genome Project (yes, that would be the sequencing/reading of ALL of the genes in a human), in 2001 the first draft of the human genome was released with the project completed in 2003 (to 99.99% accuracy and 2 years early), in 2008 due to technological advancements the costs of genetic sequencing drops with the development of next-generation sequencing platforms, the first comprehensive analysis of cancer genomes is published in 2009...


...and one of the RESULTs of all of that scientifically acquired knowledge? Modern medicine that allows targeted treatment of many genetics illnesses.

Science builds on *small* steps...
... ok, sometimes we get lucky and we get a big step, but you know what I mean...

And we *still* have a lot to learn about genetics!

This is how science is supposed to function, always improving on it's self, and how we see our world.

Celebrate Coelenterates Week!

Anemone... not anenome! ... apparently i wasn't fully awake this morning as i sketched this up... but i'm not fixing that pic right now!!! i'm just leaving it there to irritate ALL of us! ;)  )

Coming SOON! The Coelenterate CONTROVERSY!

Get Down and Celebrate Dirt! (aka Happy World SOIL Day!)

"Essentially, all life depends upon the soil... 

There can be no life without soil and no soil without life; 

they have evolved together."
