Oggi ho scoperto questo bellissimo video che spiega come funziona attualmente il sistema dell’editoria scientifica, e come invece potrebbe diventare se si puntasse di più sull’Open Access. I disegni sono del noto fumettista Jorge Cham (quello di PhD Comics), mentre le voci narranti sono di Nick Shockey (righttoresearch.org) e Jonathan Eisen (phylogenomics.blogspot.it).

Auguri mamma – A Biologist’s Mother’s Day Song
A Biologist’s Mother’s Day
To make one me you just add
Half of mom and half of dad
That is what I once believed
But now I know that I was wrong
You gave so much to me mom
Besides one half a set of genes
You gave me nutrients, transcription factors
Nearly everything that matters
Plus my prenatal environment (transplacental inheritance)
mRNA, mitochondria
That back in the day once belonged to ya (they’re cytoplasmic)
I just wanna thank you for supplying them
Just like two strands of DNA are spirally entwined
Your nature and your nurture inspiringly combine
Scientists remind me and I find that it is true
Slightly more than half of everything I am is thanks to you
Slightly more than half of everything I am is thanks to you
Mitochondria power the cell
And they have DNA as well
Transcription factors modulate transcription
Since they’re in the cytoplasm
The egg’s the only one who has ‘em
And sperm I guess they don’t have the ambition
My sex determination gene means that I’m a guy (I’m a guy)
You gave me one X chromosome, dad gave me one Y
X has over a thousand genes, while Y has less than 92
That’s why slightly more than half of everything I am is thanks to you
Slightly more than half of everything I am is thanks to you
I roomed in your womb for nine months and I’ve never paid the rent
Your glucocorticoids have shaped my hypothalmic development
I’ve took your blood and sucked it dry of every nutrient (it’s gross but true)
Sometimes I wonder where the time went (where did it go?)
Sometimes I wonder where it all went
I know I’ll never understand all you have done for me (I’m not that smart)
But since you paid for college I’ll get my B. S. degree (bachelor of science)
And I have learned it’s not BS but absolutely true
Slightly more than half of everything I am is thanks to you
More than half of everything I am is thanks to you
You gave me nutrients, transcription factors
Nearly everything that matters
mRNA, mitochondria
That back in the day once belonged to ya
Nutrients, transcription factors
Everything that really matters
mRNA, mitochondria
That back in the day once belonged to ya
Singing: Nutrients, transcription factors
Nearly everything that matters
mRNA, mitochondria
That back in the day once belonged to ya
(It’s not an even 50/50 split, you get a disproportionate share of your DNA coming from your mom. Really important)
Just like two strands of DNA are spirally entwined (double helix)
Your nature and your nurture inspiringly combine
Scientists remind me and I find that it is true
Slightly more than half of everything I am is thanks to you (it’s science)
Slightly more than half of everything I am is thanks to you
Slightly more than half of me is thanks to you
Gli alberi di Tania
Oggi voglio fare un po’ di pubblicità a un altro blog, un blog che leggo volentieri e che è scritto da una ragazza bravissima con una grande passione per la divulgazione scientifica. Lei si chiama Tania e il suo blog è Science for Passion. So che Tania ha il pallino della genetica, e anche se alla fine ha scelto di fare l’insegnante di scienze (spaziando quindi in vari settori scientifici), il suo interesse per geni e DNA traspare spesso dalle pagine del suo blog. Nell’ambito della sua ultima iniziativa, Tania ha realizzato una serie di post che aiutano i lettori a capire come funzionano gli alberi geneaologici e come è possibile utilizzarli per studiare la trasmissione delle malattie genetiche. Il suo stile didattico (apprezzatissimo dai suoi lettori) è adatto agli studenti, ma consiglio una visita anche a chi queste cose le ha studiate tanto tempo fa. Un ripasso non fa mai male!
Ieri mattina nella trasmissione Radio 3 Scienza è andata in onda un’
