DNA
Hélice dupla de DNA é fotografada pela primeira vez A cristalografia de raio-X é um processo no qual uma amostra é “iluminada” por raio-X, espalhando o mesmo. Através de uma análise matemática complexa do padrão de espalhamento do raio-X, chega-se à forma da molécula.Em 1953, James D. Watson e Francis Crick, trabalhando com cristalografia de raio-X, descobriram que a estrutura do DNA, a molécula que armazena o código genético de todos os seres vivos, tinha a forma de uma dupla hélice, ou de uma espiral. Agora, uma imagem dessa forma foi feita pela primeira vez, por Enzo di Fabrizio... mais »

"Lettre a un otage" (A.M.R. Siant-Exupèry)
Hoje de tarde conversávamos com Daniella sobre Saint Exupéry e fui rever algumas memórias Lembrei-me que na virada do século háviamos enviado para os AMICOR, e para outros amigos, a mensagem que vai abaixo e que se trata de um fragmento de um outro texto dele mal conhecido, mas que vale a pena reler. Não lembrava que a Valderês havia me lido o texto (o que está documentado na mensagem). Também me dei conta que foi em 1954 que Frei Benvenutti (Dominicano de São Paulo) me apresentou ao Pequeno Príncipe, que passei a divulgar aqui no Estado. Perguntei-me porque naquele ano? e acho que... mais »

The Beginning of Everything
The Beginning of Everything: New Paradigm Shift for the Infant Universe This image is a plot of the power spectra in the cosmic microwave background (CMB) predicted in Loop Quantum Cosmology and in the Standard Inflationary Scenario. The two different spectra are contrasted in this plot, which shows their ratio as a function of k, the inverse of wave length, of fluctuations in the cosmic microwave background. For many of the parameters, observable wave numbers k are greater than 9 and the two predictions are indistinguishable. For a narrow window of parameters, observable k can be sm... mais »

Buraco Negro
VEJA IMAGENS DO BURACO NEGRO DO CENTRO DA VIA LÁCTEA A seguros 27 mil anos-luz de distância da Terra, no centro da nossa galáxia, há um buraco negro com uma massa 4 milhões de vezes maior do que a do sol. Conhecido como Sagittarius A*, esse gigante é, felizmente, menos voraz do que buracos negros do centro de outras galáxias. Apesar disso, de vez em quando ele entra em atividade intensa.
