Emoldurada num jardim florido, no velho continente, no século passado...

Dia 15/10/2021 - quatro mêses do falecimento

Dando continuidade às Sessões Culturais da ASRM, o presidente Luiz Lavinsky e eu os convidamos para a próxima reunião, dia 19 de outubro, em formato virtual.

A palestrante da Sessão será a artista Clara Pechansky, bacharel em pintura, licenciada em Desenho e História da Arte, que conta com 70 exposições individuais no Brasil e vários países das Américas e Europa, além de mais de 200 exposições coletivas. Multipremiada, é também Gestora Social e Cultural no Brasil e América Latina. Ela nos falará sobre sua trajetória, inserida em décadas de história da arte visual no Rio Grande do Sul.

A reunião nos oferecerá mais um momento de aprendizado e beleza. Sintam-se à vontade para convidar familiares e amigos, que serão bem-vindos no ambiente da Academia Sul-Rio-Grandense de Medicina.

Este e-mail tem o propósito de "Save the Date". Na véspera da Sessão, os senhores receberão um lembrete da reunião com o link de acesso.

Obrigado e até lá!  

Miriam Oliveira (Diretora Cultural da ASRM)

What if the universe had no beginning? (Shutterstock) In the beginning, there was … well, maybe there was no beginning. Perhaps our universe has always existed — and a new theory of quantum gravity reveals how that could work. "Reality has so many things that most people would associate with sci-fi or even fantasy," said Bruno Bento, a physicist who studies the nature of time at the University of Liverpool in the U.K. In his work, he employed a new theory of quantum gravity, called causal set theory, in which space and time are broken down into discrete chunks of space-time. At some level, there's a fundamental unit of space-time, according to this theory. Bento and his collaborators used this causal-set approach to explore the beginning of the universe. They found that it's possible that the universe had no beginning — that it has always existed into the infinite past and only recently evolved into what we call the Big Bang.  Full Story: Live Science (10/12)

Scientists capture image of bizarre 'electron ice' for the first time

By Ben Turner about 11 hours ago

The crystals show electrons pressed into a honeycomb-like 'material inside a material'

Physicists have taken the first ever image of a Wigner crystal — a strange honeycomb-pattern material inside another material, made entirely out of electrons.

Hungarian physicist Eugene Wigner first theorized this crystal in 1934, but it's taken more than eight decades for scientists to finally get a direct look at the "electron ice." The fascinating first image shows electrons squished together into a tight, repeating pattern — like tiny blue butterfly wings, or pressings of an alien clover.

Scientists Who Unlocked Secrets of Pain Sensation Win Nobel Prize

Physiologist David Julius, PhD, University of California San Francisco, and neuroscientist Ardem Patapoutian, PhD, Scripps Research in La Jolla, California, have jointly been awarded the 2021 Nobel Prize in Physiology or Medicine for their discoveries of receptors for temperature and touch.

Their discoveries paved the way for new treatments for a wide range of disease conditions, including chronic pain.

"Our ability to sense heat, cold, and touch is essential for survival and underpins our interaction with the world around us," the Nobel committee, in Stockholm, Sweden, said in a news release. "In our daily lives we take these sensations for granted, but how are nerve impulses initiated so that temperature and pressure can be perceived? This question has been solved by this year's Nobel Prize laureates."/.../

Não temos nenhuma teoria definitiva sobre origem do universo, nem da vida em nosso mundo. Entretanto o modelo se repete, conforme dizia Valderês: "nada de novo é inventado, pode ser descoberto, mas já aí estava..."

O modelo do ciclo vital deve ser aplicável ao universo: tudo tem um fim e se renova. Tentamos negar a morte, mas ela faz parte da existência. Nosso mundo também deverá ter um fim...
