Vai sendo, ainda hoje, relativamente frequente a descoberta de novas espécies de animais por todo o mundo. Mas esta eu não estava à espera que fosse possível.
Um investigador da Universidade de Coimbra descobriu duas, (sim… duas) novas espécies de aranhas no Jardim Botânico da Universidade de Coimbra, que é como quem diz no meio da cidade…

Não… esta imagem, ao contrário possam pensar, não foi criada com photoshop nem nenhum desses programas de tratamento de imagem. É mesmo a fotografia de um peixe recentemente descoberto, o qual tem a particularidade de ter uma cabeça transparente.
A história é contada no link apresentado abaixo, de onde foi também retirada a imagem apresentada acima.

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/

INTERNATIONAL SCHOOL OF BIOLOGICAL MAGNETIC RESONANCE
8th Course: Biophysics and the Challenges of Emerging Threats
“This course will provide an overview of biophysical and structural methods in biology. It will present technologies related to pathogen detection and treatment using these methods. Furthermore, it will teach basic principles and demonstrate concrete examples, encouraging technology growth and transfer to partner countries.“

A team of researchers has found a feaseble way of producing universal red blood cells. This is a very important step towards the goal of improving the blood supply while enhancing the safety of clinical transfusions.
In the new study, the researchers found two bacterial glycosidase gene families with enzymes that efficiently remove A and B antigens from red blood cells (RBCs).
The reference to the the work is the following:
“Bacterial glycosidases for the production of universal red blood cells.” Qiyong P Liu, Gerlind Sulzenbacher, Huaiping Yuan, Eric P Bennett, Greg Pietz, Kristen Saunders, Jean Spence, Edward Nudelman, Steven B Levery, Thayer White, John M Neveu, William S Lane, Yves Bourne, Martin L Olsson, Bernard Henrissat & Henrik Clausen.

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

I came across this post on Pharyngula and I was speechless… The picure below, taken from an article in Science magazine [Mazur A (2007) Disbelievers in evolution. Science 315(5809):187] says it all…
Is it possible that only 35% of people with an high school level education, and 40% with a College level education and conservative political ideas believe in evolution?? (I won’t even comment the left side of the graphic…)
Read the post American political conservatism impedes the understanding of science at Pharyngula .
