Sinfonia dos pássaros...

Uma prima da nossa saudosa Dra. Valderês, com o mesmo nome dela, enviou-me o vídeo acima que tenho muito prazer em compartilhar no AMICOR. Pode nos ajudar a descobrir poesia, música e alegria em muito do que vemos todo o dia, e deixamos passar, sem dar importância...Pode contrabalançar tanta mentira e notícia ruim que somos obrigados a engulir todo o dia...

# 18/julho 1976 - Nadia Comaneci (*12/11/1961)

Lembrei-me da primeira pessoa a ganhar dez pontos perfeitos como ginasta nas Olimpíadas, nascida 18 dias antes de nossa filha, Dra. Ana Lúcia.

How Chromosomes Shape Up for Cell Division

Among the many marvels of life is the cell’s ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA – its genome – and segregate it equally into two new daughter cells. To prepare the 46 chromosomes of a human cell for transport to the daughter cells during cell division, each chromosome forms a compact X-shaped structure with two rod-like copies. How the cell achieves this feat remains largely unknown.

As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a combination of DNA looping and stacking. Image Credit: Daniela Velasco Lozano/EMBL

Richard Feynman e John Wheeler revolucionaram o tempo, a realidade e o nosso universo quântico

Elton Wade

Um novo olhar para as vidas entrelaçadas de duas das maiores mentes do século XX.

Uma visualização da QCD ilustra como pares de partícula / antipartícula emergem do vácuo quântico por quantidades muito pequenas de tempo como consequência da incerteza de Heisenberg. Nossa compreensão do universo quântico continua a evoluir com o tempo, e Feynman e Wheeler foram dois dos físicos que empurraram a agulha para frente como nunca antes. Crédito da imagem: Derek A.
