Nossos cumprimentos ao recém empossado Magnífico Reitor da Universidade Federal de SM (minha terra natal). O avô mencionado por ele -Vitor Francisco Schuch - foi meu amigo no início da década de cinquenta, pouco antes de eu deixa a cidade. Tenho também saudade, e gratas recordações do Chefe Vitor - criador do Clã de Pioneiros Ibitory-Retan (nome indígena do local onde se desenvolveu a cidade) - Hoje, um neto meu - Pedro Martin Achutti Olivé - tem como Reitor, um neto do Chefe Vitor.
Aproveito para agradecer mais uma vez, na pessoa do neto, as belas aventuras que tive com seu avô, e ao mesmo tempo enviar meus votos de sucesso.

Surgeons transplant pig's heart into dying human patient in a first
Doctors have transplanted the heart from a genetically modified pig into the chest of a man from Maryland in a last-ditch effort to save his life. The first-of-its-kind surgery is being hailed as a major step forward in the decades-long effort to successfully transplant animal organs into humans.

Clocking Memories
A new study helps clarify how the brain keeps a record of the timing of events by firing special neurons called “time cells,” as Abdulrahman Olagunju reports for Scientific American. Although scientists have known certain cells time-stamp our memories, they haven’t known how. In 2019 Jordana Cepelewicz wrote for Quanta about one theory: Our brain encodes the information with a mathematical function called a Laplace transform.

Clarified Incompleteness
A logic puzzle from Alex Bellos for The Guardian illustrates a simplified proof for Gödel’s incompleteness theorem. While simple logic puzzles can capture its essence, Gödel’s actual proof is much more involved. Natalie Wolchover explained how it works for Quanta in 2020.

Pizza’s dominance on the international gastronomic stage hinges not on a glorious past rooted in antiquity so much as an anthropological phenomenon that has come to be known as the “pizza effect.”

#The New York Times Book Review

“The most important Cultural Revolution document published in China in the 1990s, this harrowing, stylishly written book’s English-language edition benefits from Chenxin Jiang’s deft translation and Zha Jianying’s superb introduction.”
—Jeffrey Wasserstrom, Financial Times

THE COWSHED
MEMORIES OF THE CHINESE CULTURAL REVOLUTION

Ji Xianlin Translated from the Chinese by Chenxin Jiang. Introduction by Zha Jianying

Ji Xianlin was a professor of Sanskrit at the prestigious Peking University. An early member of the Chinese Communist Party with a working-class background, he was an ideal citizen in communist China. But in 1966 a student-led coalition, the Red Guards, began to call out the supposed elitism of teachers and intellectuals. Thus started the Cultural Revolution, a time of censorship and extreme discipline in the upper reaches of the academy, but also one when millions of people were imprisoned and starved and countless died.

Refusing to go along with the baseless attacks and internal power squabbles at the university, Ji was labeled a counterrevolutionary and was subjected to a year and a half of torture, and finally a year of detainment and physical labor in appalling conditions. His faith in the Communist Party and all it had stood for was shattered. The Cowshed recounts this excruciating experience in a narrative full of sharp irony, empathy, and remarkable insights into a central event in Chinese history.

“At the center of Ji’s account, ably translated by Chenxin Jiang, is the ‘cowshed’ of the title. . . . Ji’s description of this institution, really a kind of mini concentration camp, is unforgettable.”
—Richard Bernstein, 
The New York Times Book Review

Opportunity From Ashes
The introduction of non-native pine trees decades ago has created a wildfire problem in Patagonia today, Guido Bilbao reports for National Geographic. Forest fires aren’t always bad for nature, though. As Carrie Arnold reported for Quanta, fires can create opportunities for diverse plants and animals, forming a patchwork quilt of ecosystems in a single forest.

You Won't Feel a Thing
Asteroid-mass black holes could be roving our solar system, waiting to collide with Earth. But don’t worry, says Matt O’Dowd for PBS Space Time: A black hole so small would pass through Earth “like a bullet through cotton candy.” Some physicists suspect that the 80% of the matter in the universe that’s unaccounted for could be tiny primordial black holes, as Stephen Hawking first proposed. In 2020, Joshua Sokol wrote about this theory for Quanta.
