Discover8 is a new scientific communications database where registered users can suggest, comment and rate scientific communications. Its also possible to recommend any article with a valid web link (for instance your own articles 
).
A large number of topics related to life sciences are present.
Take a look at it at http://www.discover8.com/
We all know that an important part of the scientific work is related to communicating your findings to your peers. So here are a couple of texts on the subject (from the “Improbable research” site). I hope you find them useful .
“How to write a scientific paper“, by E. Robert Schulman
” How To Make a Scientific Lecture Unbearable” , by Alexander Khon
DISCOVER has presented a list of some of the best/most important scientific writing of all time. I think that the title “25 Greatest Science Books of All Time” is a little bit too much, but still… anyway one can always vote to set the record straight.
To see the list click here.
Just one more thing… did anyone notice that there isn’t any book refered here about chemistry? Or did I miss it?
You can find another post about the list at Blogui-ci.
This post is more a bookmark for myself but I don’t mind sharing with all of you who visit this blog.
Nature magazine has compiled the list of (the most) popular science blogs at the present, based on the Technorati ranking. The list is here.
I imagine that with this “publicity” the traffic in these blogs wil increase exponentially, and next year they will be even more at the top. .
The list is also refered in: http://blogomica.blogspot.com/
The first time the work of Lionel Moura was brought to my attention, my first reaction was: “It is an interesting exercise but is it art?”. Then, as now, I somehow feel that art implies some kind of intelectual process by the creator of the work. One must ask: is a set of totally random lines created by robots a work of art? Or in the same line of thought, when does a broken glass bottle ends being trash and becomes being something worth to be shown in a museum of modern art? Anyway if the artistic community takes him seriously who am I to say his is not art. I’m not arguing “if it is nice to look at”. My doubts are about the process of the artistic creation.
This question is completely put aside on other work of the artist such has in the “section” Voronoi paintings.
Anyway, the best way to get to know his work is to go to his own web page and browse around the site. There you can find the extensive list of examples of the work by the artist (paintings created by robots with some kind of “artificial intelligence”, the paintings based on the work of Voronoi and many other creations.). Texts about his ideas and concepts about art and the cv are also available.
Check it out. It’s worth it.
Just for you to have an idea of what is going to be auctioned tomorow here is a small list with few examples:
