# 27/07/2025 Dia chuvoso...

Dr. Sérgio de Paula Ramos enviou-nos hoje pela manhã esta bela imagem de uma Saira-Lagarta verde- amarela, para um grupo de membros da nossa Academia Sul-Riograndense de Medicina, foto recentemente feita na companhia do confrade Jorge Neumann. Parabéns!...

# Dia dos Avós, teria sido ontem

             2025 - Neto                                       1951 - Avô                                    1916 - Bisavô

O mais novo de meus netos, Eduardo, formado pela Universidade de Roma, chegou há dois dias para a formatura pela UFRGS da irmã, Júlia, minha primeira neta. Meu filho, Professor Luiz Eduardo, pai dele, contou-me que este diploma é um de seiscentos mil, da Universidade que tem setecentos anos...

Achei a fisionomia dele, e o olhar, parecidos com o bisavô dele, Bortolo (*28/10/1898+19/11/1977), avô do pai dele, e meu pai (quando tinha 18 anos, serviço militar).

Achei a fisionomia dele, e o olhar, parecidos com o bisavô dele, Bortolo (*28/10/1898+19/11/1977), avô do pai dele, e meu pai (quando tinha 18 anos, serviço militar). Tenho mais dois netos entre os dois já citados: o Pedro Martin na Universidade de Santa Maria e o Antônio na nossa Universidade e nas nossas Orquestras. Em próximas edições eles aparecerão.

#Scientists discover two drugs already 

approvedby the FDA can reverse Alzheimer's 

Two drugs already approved by the FDA for cancer treatment may hold the key to reversing Alzheimer's disease in patients, experts say. 

Researchers from the University of California, San Francisco (UCSF) believe that letrozole, a hormone-based breast cancer drug, and irinotecan, a lung and colon cancer chemotherapy medication, can help reverse brain damage caused by the incurable neurodegenerative disease.   /.../

 3.205 AMICOR

20/07/2025 o dia de hoje é anunciado como o Dia do Amigo, eu não poderia retardar mais a nova edição de nosso AMICOR. Uma grande amiga de nome ZILDA que teve um papel muito importante em nossas vidas há mais de 55 anos, enviou-me uma mensagem com a frase do Mário Quintana que desejo compartilhar com nossos AMICOR. Valderês e eu fomos padrinhos de seu primeiro filho, a quem desejamos incluir no mesmo abraço.

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.
