Feliz Navidad y Próspero Año Nuevo. Happy Holidays!


Sé que es una de las frases más trilladas en estos tiempos, y que muchas veces la decimos sin una verdadera intención y deseo de que se haga realidad para quien se lo deseamos. Así que, sinceramente, les deseo una feliz navidad y un próspero año nuevo. De corazón deseo que sus metas lleguen a cumplirse y que sus deseos sean alcanzados, no por simple intención, sino por su propio esfuerzo y dedicación, por convicción. Así como aprovechar el año que viene para hacer lo que no se hizo o dejar de hacer lo que no fue provechable.
Este será la última entrada de este blog en este año. Nos veremos el próximo con más aventuras.
Espero Grado Reactivo levante y podamos ver nuevas entradas el próximo año, pues creo que tiene mucho que dar nuestro compañero Rotcives.


I know the phrase Merry Christmas and happy new year is a well-known phrase thesedays, but I must say also that many times we don't really say it from the bottom of our heart. So here I come: "Merry Christmas and Happy New Year!". I really wish you the best. This is a time for thinking in things that we did, things that we didn't do but should be done, or things that would be better stop doing. Every year is a new opportunity to take care of the important things and to try to be a better person as well as to enjoy every happy moment, no matter the bad things or the hard situation that we are passing at this moment.

So this will be the last post of my blog within this year. I'll see you next year!
Happy holidays!

Nuestro personaje del Mes: Fredrik Ronquist

Bueno, tarde pero sin sueño, les dejo a continuación una entrada mensual que empieza a ser clásica en este blog, titulada Nuestro personaje del Mes.

Well this post is becoming a tradition in this blog, every month I'll post a special review of a prestigious researcher, writing down some of his/her bibliography, research areas and published papers. Hope you enjoy it. If you have comments or ideas for new researchers let me know about them.

Bueno este post lo dejo en inglés porque sé que mis "asiduos" lectores están capacitados en el idioma inglés y porque además tengo alguno que otro gringo que visita my blog.


Dr. Fredrik Ronquist
Personal data: Born 9/28/1962, married with Eva, three children born 1990 (Ebba), 1992 (Filippa) and 1995 (Axel)
Home address: 3711 Longfellow Road, Tallahassee, FL 32311, USA, (850) 878 0728
Work address: School of Computational Science, Florida State University, Tallahassee, FL 32306-4120, USA, voice (850) 645 1325, fax (850) 644 0098
Email: ronquist@csit.fsu.edu

Dr. Fredrik studied a PhD in Upsala University in Sweden. He studied the comparative morphology, phylogeny, and evolution of cynipoid wasps. Then he spent few years at the Swedish Museum of Natural History in Stockholm. Then He went to Florida State University in 2003 to join the computational evolutionary biology group at the School of Computational Science.

I guess Fredrick has done many stuff related to taxonomy and systematics, but he is well know because of his efforts in computational biology and phylogenetics. He got involved in the development of parsimony methods for the study of coevolution and biogeography (DIVA and TreeFitter) and more recently Bayesian MCMC methods for phylogenetic inference (MrBayes), which is coautor with John Huelsenbeck.

Nowadays he is involved in many research projects, I'll just name few ones:
1.- Extending Bayesian Phylogenetics
2.- Morphbank
3.- HymAToL
4.- PCC
5.- The Swedish Taxonomy Initiative

Also, Fredrick has been involved in teaching courses in entomology, evolutionary biology, phylogenetics and comparative genomics, mostly at the advanced undergraduate or graduate level. There are several lectures online available related to phylogenetics.

His current work address is School of Computational Science, Florida State University, Tallahassee, FL, where he has a lab with some students doing phylogenetic research.

Well, there are many things to say about this experienced researcher in phylogenetics, but I'm about to finish this post writing down some of his published papers, and also the link for the website of Ronquist Lab, just in case you are interested on looking for more information about him and his projects.

I guess Ronquist is our researcher of the month because he's been spent many years working on improving phylogenetic tools for analysis and for the development of software for phylogenetic research. I think MrBayes is one the outstanding tools for phylogenetic analysis, which allows us to analyse and generate hypothesis about how evolution has shaped living organisms' life on earth.


I must say, thanks Dr. Fredrick Ronquist for our efforts on this area of research: Phylogenetics.

Google_Chrome for linux... ahh, finally

Well after a long time of no-posting attitude, now I'm pretty happy to announce that Google has implemented its great web navigator for linux: Google Chrome. I've been using Chrome for a couple of months in Windows Vista and I must say it's a good web browser. So I think would be nice to test it for linux (ubuntu in my case).

I encourage you to give it a chance to Google Chrome.
I attached an image that I took from Google Chrome website just depicting the great effort done to make Chrome available for linux users.

Best regards!

Gaceta Paleogenómica

Bueno sólo quiero dejarles este nuevo documento que distribuye el lab. de DNA antiguo, que parece interesante, pues señalan algunas cosas sobre los proyectos que están realizándose y en particular sobre la aprobación del financiamiento para el proyecto de DNA antiguo sobre restos humanos del
barrio de Teopancazco de la antigua Ciudad de Teotihuacan. "..Con esto se busca dar respuesta a varias interrogantes genéticas de los grupos que poblaron esta metrópoli", dice la gaceta y creo que es interesante en el futuro analizar los resultados que salgan de esta investigación, pues permitiría hacer inferencias sobre el movimiento y dinámica poblacional de dicho lugar en aquellos momentos.

Espero sea igual de interesante para ustedes como lo fue para mi.

Introducing...

Bueno, les dejo en este post una imagen de mi nuevo widget de comentarios, aquí pueden dejar sus sugerencias acerca del blog, ya sea cosas de estética, algo que le falte o simplemente quejas o comentarios ajenos a cualquiera de las entradas que he escrito a la fecha, así no gastarán cartuchos escribiendo comentarios que no se relacionen a las entradas del blog.



Sólo ocupan poner su correo, nombre (o nickname) y si quieren el lugar donde se encuentran, luego ponen su comentario y ponen una clave de letras (la parte más difícil) y listo: los comentarios se van apilando uno tras otro y pueden checar todos allí mismo.

Espero la usen y dejen sus comentarios y sugerencias extra-entradas.

Saludillos!
