#Neto novo

Há mais de dez anos, desde quando a Dra. Valderês ficou doente, eu comprava cataventos de jardim, que ela aparentemente gostava de ver. De material muito frágil, com o tempo se deterioravam. Fui procurar e não mais encontrei reposição. Como temos Jardim da Infância nas redondezas, é frequente ver crianças parando para apreciar os ícones. Fiz a reposição agora com um novo de material mais resistente, e o chamei de "neto novo"...Espero que os passantes também gostem do novo modelo...

#Acadêmico Jorge Neumann

Tive o prazer de adquirir o belo livro "A vida entre o céu e a terra" no seu lançamento, em estabelecimento da rua Vigário José Ignácio que, casualmente, no meu tempo de recém chegado a Porto Alegre, chamávamos de Colégio dos Anjos, pensão de moças, dirigida por freiras, bem em frente da Casa da JUC no.1 na qual fiquei hospedado. Já no decorrer de 1953 me mudei para a Casa de no.4, na 24 de Outubro 575, que dirigi até 1957 quando casei.

An extrasolar world covered in water?

An international team of researchers led by Charles Cadieux, a Ph.D. student at the Université de Montréal and member of the Institute for Research on Exoplanets (iREx), has announced the discovery of TOI-1452 b, an exoplanet orbiting one of two small stars in a binary system located in the Draco constellation about 100 light-years from Earth.

Immortal jellyfish genes identified explain their long lives

By performing a DNA comparison of two similar jellyfish species, researchers have found the genes that could stop and reverse ageing in immortal jellyfish

One jellyfish’s regeneration powers seem linked to key genetic changes.

An immortal species of jellyfish has double copies of genes that protect and repair DNA. The finding could provide clues to human ageing and age-related conditions.

Jellyfish start their lives as drifting larvae. They eventually attach to the seafloor and develop into sprout-like polyps. The bottom-dwellers clone themselves, forming stacked, sedentary colonies that bud off into free-swimming umbrella-shaped medusas.

That stage is a dead end for most jellyfish – but the immortal jellyfish (Turritopsis dohrnii) can reverse the cycle. When times get tough, like in harsh environments or after injury, they melt their bodies into amorphous cysts, reattach to the seafloor and regress into polyps. They can restart the cycle indefinitely to skirt death by old age.

Now, researchers have discovered how to unearth clues about when the volcanoes will erupt by analyzing vibrations from the ice, reports Rachel Berkowitz for Scientific American. Scientists are also coming up with new and creative ways to predict earthquakes from mathematical models of the “geological pinball,” as Robin George Andrews covered for Quanta in 2020. Chips on the Brain Using soft and flexible materials, researchers are designing computer chips that mimic the processing capabilities of neurons in our brains. One day, they might even be able to link up directly with biological neurons, reports Kurt Kleiner for Knowable Magazine. Many of these new devices, called neuromorphic chips, aim to match the brain’s ability to perform energy-efficient analog computing. In February, Allison Whitten reported for Quanta on a new technique that allowed researchers to overcome one large hurdle on the way to analog computing.

#Profa. Dra. Maria Helena Cechella Achutti (minha irmã)

A foto é de 2008, quando Lia Maria - que não está mais conosco - completou seus oitenta anos. No dia de hoje (03/09/2022) Maria Helena completa seus 92. Meu grande abraço, e agradecimento por me acompanhar, e votos para que possamos continuar ainda saudáveis daqui por diante, gozando do convívio de nossa família, e do afeto de nossos amigos.
