Acceso libre a la investigación financiada con fondos públicos


Estimados colegas
En estos tiempos que corren (literal y figuradamente) la evolución de las
pautas de diseminación de los resultados de la investigación parece
encaminarse a un sistema donde sólo unas pocas grandes editoriales dominan
el negocio. Ello lleva a que los resultados de una investigación financiada
con dinero público se publiquen en revistas de alto prestigio, pero que son
inaccesibles para la gran mayoría, por los precios prohibitivos que se cobra
por el acceso.

Existe en estos momentos una iniciativa europea que intenta cambiar esa
política, al menos en la EU. Os invito a leer, y si lo consideráis oportuno,
firmar la declaración disponible en :http://www.ec-petition.eu/

Saludos

Primates may have come along earlier than thought

Article published Jan 16, 2007

Jan 16, 2007



Primates that eventually gave rise to human beings came on the scene shortly after the extinction of dinosaurs, a full 10 million years earlier than the fossil record has ever conclusively illustrated, according to a new paper co-authored by a University of Florida faculty member.

Jonathan Bloch, curator of paleontology at UF's Florida Museum of Natural History, says his team's paper gives the first conclusive evidence that modern-day primates find their roots in mammals that lived 65 million years ago. Prior to this paper, the fossil record has only conclusively shown primates appearing 55 million years ago; what happened before then has been a matter of educated conjecture, Bloch said.

"The question (about primates) has been, where did they come from? What did they evolve from?" he said.

According to Bloch's conclusions, primates evolved from a mammal about the size of a small mouse with a skull no bigger than a grape. Other scientists have previously suggested these tiny archaic primates, called plesiadapiforms, could have been the earliest predecessors of primates. But Bloch was able to add new credibility to that hunch with a fossil discovery he made near Yellowstone National Park.

Accompanied by Doug Boyer, a graduate student in anatomical science at Stony Brook University and a co-author of the paper, Bloch ventured east of Yellowstone to Big Horn Basin near Cody, Wyo. By carefully dissolving freshwater limestone with acid, the crew uncovered the complete skeletons of two new species of plesiadapiforms, giving a holistic picture of the bodies of these animals and their primate features. Before that fossil discovery, scientists had been limited to fossil fragments like teeth, which didn't provide enough evidence for a scientifically acceptable conclusion about whether they were primates, Bloch said.

"(The new fossil) allows us to say these things are much more like primates than you could ever say looking at their teeth," Bloch said.

One of the species, called the Dryomomys szalayi, is the most primitive primate skeleton ever discovered, Bloch said, providing a picture of life tens of millions of years ago.

Bloch's paper, which will be the cover story in the Jan. 23 edition of "Proceedings of the National Academy of Sciences," helps to form a picture about exactly what happened on Earth after the dinosaurs went extinct. Mammals that had formerly kept a "low profile" in order to avoid the tenacious dinosaur literally began to branch out, moving farther along tree limbs to access food.

During a period of some 10 million years after dinosaurs went extinct, the emboldened and evolving plesiadapiforms became more like primates we know today, Bloch said. The early fossils suggest these animals would have initially only been capable of rudimentary grasping like a squirrel. But over time they would take on the characteristics of modern primates, which have grasping hands and feet, nails instead of claws, relatively large brains and an ability to jump from tree to tree, Bloch said.

Bloch's research wouldn't have been possible without the fossil discoveries of the two new species of plesiadapiforms he found in Big Horn Basin. What's fascinating about one of these fossils, Bloch says, is that it so closely resembles a tree shrew. That observation may not mean much at a cocktail party, but for paleontologists it demonstrates something rather remarkable. The tree shrew is a close relative of the primate, and this fossil - not surprisingly - illustrates a common ancestor between tree shrews and primates further down the evolutionary chain.

So what can be learned about humans from this apparent breakthrough?

"Ultimately, what it does is helps us understand where humans fit into the tree of life," Bloch said.

Along with Boyer, Bloch's paper is co-authored by anthropology professors Eric Sargis of Yale University and Mary Silcox of the University of Winnipeg.

Sis persones s'engabien en un zoo australià per estudiar les condicions dels grans simis en captivitat

Un grup de sis homes i dones han reemplaçat avui els orangutans al tancat d'un zoo australià per participar en un projecte d'un mes batejat com el Zoo Humà.

Els nous espècimens del zoo d'Adelaida s'exhibeixen darrere de llargs panells de plexiglàs i són filmats per càmeres. Instal·lats en un recinte que anteriorment estava ocupat per orangutans, els participants faran rotacions d'una setmana en grups de sis, encara que tindran el dret de tornar a casa seva a la nit, quan el zoo tanqui al públic.

Els visitants del zoo són convidats a triar el seu humà preferit i els experts estudiaran el seu comportament, amb l'objectiu de millorar les condicions de vida en captivitat dels grans simis.

Observats per milers de visitants

Carla Litchfield, experta en psicologia animal de la Universitat d'Austràlia Meridional, serà l'única persona que passarà el mes sencer al Zoo Humà.

"Mai he sabut el que era [la captivitat]. Passar un mes en el tancat em donarà una bona idea de les olors, els sons i del que significa ser observada per milers de persones cada dia", ha explicat Litchfield a la ràdio ABC.

L'experiència pretén a més reunir fons per a un nou tancat per a ximpanzés.

Malgrat que el zoo d'Adelaida afirma que es tracta d'una primícia mundial, no es tracta d'un fet inèdit. L'agost del 2005, al zoo de Londres, vuit voluntaris també es van tancar durant alguns dies en una gàbia.

Veterinaris dels EUA recepten Prozac a gossos i gats per corregir el seu comportament

Els veterinaris dels EUA recepten tractaments antidepressius per curar les alteracions del comportament, l'ansietat i l'agressivitat dels animals de companyia.

Si un gat esgarrapa tots els mobles o fa pipí a cada cantonada de la casa és molt possible que estigui deprimit. Per corregir aquests comportaments, els veterinaris nord-americans recomanen que els felins ingereixin mitja pastilla de 10 mil·ligrams de Prozac una vegada al dia.

Aquest tractament s'utilitza en gats i gossos, però també és útil per a cavalls i altres animals que demostrin, a la seva manera, que necessiten ajuda.

Reduir l'agressivitat o estimular la gana

Richard Martin, propietari de la clínica veterinària Brentwood, ha afirmat a la publicació Los Angeles Times que fa cinc anys "s'administraven antidepressius a menys de l'1% dels nostres pacients. "Avui el 5% dels gossos i gats hospitalitzats a la clínica prenen fàrmacs per reequilibrar el seu comportament", ha afegit.

"Es tracta d'una solució a una patologia greu, que si no es resol pot portar els propietaris a abandonar els animals o a acabar amb ells", ha dit el veterinari.

Fàrmacs psicoactius

El 2001 la Universitat de Califòrnia va publicar una investigació que va demostrar que la fluoxetina, un component del Prozac, redueix el pipí compulsiu dels gats. Elyse Kent, directora sanitària de l'hospital per a gats de Los Angeles, assegura que fa 12 anys que cura els felins amb fàrmacs psicoactius perquè no "orinin de manera compulsiva o perquè no siguin agressius amb els propietaris".

Curtis Eng, cap de la unitat de metges del zoo de Los Angeles pensa que els antidepressius a vegades són necessaris per complementar les teràpies tradicionals i posa com a exemple el cas de Minyak, un mascle orangutan que, a causa d'una insuficiència respiratòria, no menjava prou i els antidepressius li van estimular la gana. Gràcies a la teràpia es va recuperar i va tenir un fill el 2005.
